The Plastic Machine Can't Open The Mold Again, There Is Pressure, There Is Speed, There Is Oil To The Cylinder, The Pressure Is 125kg, Why Is It Often Unable To Open The Mold?

The plastic machine can't open the mold again, there is pressure, there is speed, there is oil to the cylinder, the pressure is 125kg, why is it often unable to open the mold?

1. Whether the skeleton seal of the mold-opening cylinder is damaged.

2. Whether the clamping mechanism is partially stuck.

3. Check the mold opening valve; see if the valve core is not timely.

4. Are the speed and pressure, the main parameters of the site appropriate?

5. Whether the mold opening part has arrived. Look at the interface to check the electronic ruler or the mold opening stop limit switch. 6 If such problems often occur, first check the part of the oil passage, but the mechanical equipment part should be mainly checked to see if there is wood The crankshaft connecting rod is worn or unstable.

When the mold is opened manually, everything is normal. But in the semi/automatic mode, when the mold is opened to the setting position, it stops for a while without stopping, and then the information is displayed at a slow speed. Quickly set the P and F values. To make the mold opening exceed Process cannot be produced.

Basic Clear:

①P, F are set too large; there will be no problem of inertia force of mold opening.

②The electronic ruler has been replaced.

③The program flow check that everything is normal.

1. There is no setting for the mold-opening condensing type or common faults in the oil passage related to this.

2. The setting of the change point of the mold opening speed and slow speed is unscientific.

3. Check the valve core of the mold opening relay.

4. Check the P.Q valve to see if the valve core moves linearly.

5 Whether there is a signal termination lag in the output on the computer.

6 The mold opening pressure and flow setting are very large.

There is a Taiwan Strait Sky 240 aircraft, which has been in active service for less than ten years. More than a year ago, because the mold was often not opened, the whole set of machine hinges was replaced before. In July 2020, the machine could not be opened after locking the mold again, and it had to be ringed by human resources. In August, everyone replaced the whole set of the machine hinge steam insulation pipe, but the problem was not completely eliminated, and the old problem often occurred. Details: 1. When the mold was clamped to the bottom to press the maintenance part, the two cross pendulum rods were lifted upwards. There is a sign of being pressed down when the mold is opened. The reason why the mold cannot be opened is precisely because the cross cannot pass which point ※, so a knock is equivalent to adding a little external force. The mold has been opened; 2. It has already been used Countermeasures: In addition to replacing the hinged steam insulation pipe, the cross bushing was replaced, and the balance was adjusted after suspecting that the Colin column was unbalanced, but the common faults remained!

1. Replace the 2 guide rods of the cross head! Suspected deformation.

2. It is possible to adjust the feet of a mobile board, and raise the mobile board a little bit, and the equipment will be used for too long, and the mobile board will move down due to wear and other reasons.

3. It is determined that the common fault is caused by the inconsistency of the left and right bending arms due to the fact that each process is not repaired according to the origin when the mobile phone hinge steam insulation pipe is first disassembled and replaced. It should be included in the list of replacement machines of the enterprise. When the machine is turned off, it is absolutely not allowed to press and lock the mold.

There is a plastic machine that has this kind of situation 4 times. Before, it used to expand the system software pressure and total flow; hit the flex arm with a hammer; use a hydraulic jack to open it with the driver's back. And this time, the above methods are used It can't be opened after passing, and the 4 positioning pin screw caps can't be loosened. Is there any other way to open this device.

1. Loosen the nut connecting the hydraulic cylinder of the clamping cylinder and the cross by one centimeter up and down, and then open the mold, using its inertia force should be opened by 70%

2. Set the slow-speed mold opening part to 0, and the rapid mold-opening pressure and speed to be larger. Try

3. Check the flexion arm, there must be wear (replace)

4. The pendulum rods on both sides of the clamping cross are loose. It can be opened immediately. In addition, the equipment should adjust the interval of the four columns, or it will continue to fail to open.

5. The first thing to distinguish is the power circuit problem or the oil passage problem. When the mold is not opened, check whether the 24V power is applied to the relay and whether the system software is under pressure.

6. There is also a problem with the electronic ruler. Check whether the data of the electronic ruler is appropriate when the mold is not opened.

7. Put the hydraulic jack in the middle of the flex arm cross and the injection cylinder to make it tight, and then use a little mechanical equipment to open the mold.

8. Evenly clamp and fix the screw around the mold, (ensure the symmetry of the 8 screws). After confirming that the mold installation is correct, adjust the mold opening buffer, reduce the mold opening speed, and then successively Increase mold opening pressure.

The front protective door is opened during automatic operation, and the mold is automatically opened. I don't know where is the problem?

1. The program flow setting requires that the protective door (imported product) cannot be opened before the injection posture is performed during fully automatic operation.

2. Check the protective door limit switch!

3. Check whether the mode locking stops the I/O observation

4. The program flow is unsuccessful (everything is normal in China)

After the mold is opened, why does it continue to bounce back up to 20mm?

1. The setting of the mold opening stroke is unscientific, the pressure of the cache rate is high, and the parts are small.

2. If there is gas in the mold cylinder, there is also this phenomenon.

3. It should be gradually crawling 20mm during injection. If so, check the clamping valve.

4. The negative correlation of the hydraulic reversing valve and the hydraulic seal of the oil cylinder should be checked. There is also a tangent slope of the pressure.

5. Adjust the opening and closing according to the countersunk head screw to adjust the hydraulic reversing valve of the opening and closing mold. The internal guide oil Xiaomenzi (X, Y) can reduce the

6. It is also possible that the air filter of the car fuel tank blocks the exhaust pipe and the exhaust pipe is not smooth! 7 Unlock the inner leakage of the mold cylinder. Check the inner leakage of the piston rod sealing ring and the outer thread between the piston rod and the hydraulic cylinder.

Just after the injection of the plastic machine, there was a sudden power failure. After 4 hours of dialing the phone and starting the equipment, it was found that the mold opening could not be opened. What should I do?

1. Check if something is burned in part of the open-die power supply circuit (in the case of no output)

2. It's a matter of the mold. Due to the power outage for a long time, and there are goods in it, it has been swelled at once.

3. It may be that the relay of the power switch mode is stuck. Add one more pressure to open the mold and try it

4. Open the mold after adjusting the PQ. Then repair it. 5 If it is not good, you can only use the hydraulic jack to open the mold.

When the 150T shooting table is in the position or the plastic injection position, the mold will gradually open, and the hydraulic reversing valve for opening and closing the mold has also been changed many times, but the problem cannot be solved.

1. Have you checked the hydraulic control valve under the power switch mold valve to see if one of the two sides is broken.

2. If the mold clamping is too tight, adjust it again (when fully automatic)

3. Clamping cylinder skeleton seal internal leakage inspection (when fully automatic)

4. The pressure of the limit switch at the end of the clamping mode is too forward (when fully automatic)

The equipment that is usually produced and manufactured normally, after a restart, a strange inertial force suddenly appeared. Press the open mold in the manual mode, and then release it immediately, the mold will continue to follow the original path without stopping. After exercising for a certain distance, closing the mold, and the Sagittarius all have this kind of situation. I don't know the reason.

There is a small plastic machine here, and the common faults are as follows: the pressure gauge displays information to 140 when the mold is clamped and the front, rear, left, and right shooting tables are closed (the mold clamping high pressure bar has not reached the stop power switch), but there is no pressure in the mold opening, and it is When the mold is opened, the steam pressure of the mold will be displayed at once, but the mold cannot be opened.

1. Is the mold opening valve stuck?

2. Check whether there is no pressure in the clamping pressure?

3. Check the opening and closing of the mold cylinder, and you can exchange the two oil pipes and try to determine whether there is internal leakage.

4. The inner skeleton seal of the opening and closing mold cylinder is damaged.

There is a Haitian injection molding machine, the computer is from Japan Boshi, in the whole process of production, the mold opening has not reached the precise positioning, (the part is set to 800, while the site part is on 801.9), an alarm always appears, and the mold opening rate It has been slow for a long time, and it is still not good. Check the electronic ruler and it is not loose. I want to ask what is the reason.

The difference is that the value setting of the reasonable area of the mold opening is too small! Change the allowable error value of the reasonable part to a larger value. Look at the main parameters, set a number above ten and see!

The plastic machine is closed after the production is completed, and the mold cannot be opened when it is gradually completed the next day. What's the matter?

1. It must be in the case of mold clamping when the machine is turned off, and the mold clamping part is under high pressure, and a vacuum pump and suction force are generated in the mold.

2. The parts of the opening and closing mold are moved and damaged, and the oil is less. 3. There is gas in the oil passage of the opening and closing mold.

After the equipment closes the mold, the mold cannot be opened. In the manual mode, pressing the mold opening does not respond at all, and the mold opening pressure also displays a message of 0. Pressing the mold closing key pressure displays a message of 35, which is the normal standard value. . i want to ask what is going on

1. Increase the pressure and speed to open the mold and take a look!

2. The pressure pre-adjustment means that the total pressure of the system software is increased before opening.

3. Check the seal of the piston rod skeleton of the opening and closing die cylinder

4. Whether the two proportional ammeters are working, you can also increase the current to turn on

5. The data signal of manual mold opening is not sent to the inside of the control panel on the computer. First, check whether the pressure gauge of other posture gauges, the pressure and the total flow ammeter are all normal. Adjust and increase the pressure and try it! If the equipment is all normal If it still can't be opened, check the oil passages, mold opening parts, etc.!

After the injection molding process of the product during the processing, the mold cannot be opened under the fully automatic condition

1. First determine whether there are commodities in the mold, and then there are differences

2. Then determine the operating conditions of manual and fully automatic situations.

3. Mold opening signal, mold opening relay, total pressure flow status

4. Check whether the pressure is released under the automatic condition.
