Mold Try Out For Automotive Inlet Tank Mold
First, Matters needing attention before mold trial
1. Understand the relevant information of the mold:
It is best to obtain the design drawing of the mold, analyze it in detail, and ask a mold technician to participate in the trial work.
2. First check the mechanical coordination action on the workbench:
Pay attention to whether there are scratches, missing parts, looseness, etc., whether the movement of the mold toward the slide plate is correct, whether there is leakage in the water channel and air pipe joints, and if there are restrictions on the mold opening, it should also be marked on the mold. If the above actions can be done before hanging the mold, it is possible to avoid the waste of man-hours when the problem is found when hanging the mold, and then to disassemble the mold.
3. When it is determined that each part of the mold moves properly, it is necessary to select a suitable test mold injection machine, and pay attention to the selection
(a) Injection capacity
(b) Width of the guide rod
(c) Maximum departure
(d) Accessories
4. Increase mold temperature:
According to the properties of the raw materials used in the finished product and the size of the mold, an appropriate mold temperature controller is selected to increase the temperature of the mold to the temperature required for production.
After the mold temperature is increased, the movement of each part must be checked again, because the steel may cause a jam phenomenon after thermal expansion, so pay attention to the sliding of each part to avoid strain and vibration.
5. If the experiment plan rule is not implemented in the factory, we suggest that when adjusting the test conditions, only one condition can be adjusted at a time in order to distinguish the impact of a single condition change on the finished product.
6. According to the different raw materials, do a moderate baking of the raw materials used.
7. Try to use the same raw materials as much as possible for mass production in the future.
8. Do not try the mold completely with inferior materials. If there is a color requirement, you can arrange the color test together.
After checking the above steps, lower the mold closing speed and pressure, and set the safety hook and ejection stroke, and then adjust the normal mold closing and closing speed. If the maximum stroke limit switch is involved, the mold opening stroke should be adjusted slightly shorter, and the high-speed mold opening action should be cut before the maximum stroke of the mold opening. This is because the high-speed movement stroke is longer than the low-speed stroke in the entire mold opening stroke during mold loading.
Please check the following items again:
(a) Whether the feeding stroke is too long or insufficient.
(b) Whether the pressure is too high or too low.
(c) Whether the filling speed is too fast or too slow.
(d) Whether the processing cycle is too long or too short.
In order to prevent the finished product from short shot, fracture, deformation, burrs and even damage to the mold.
If the processing cycle is too short, the thimble will penetrate the finished product or squeeze the finished product by peeling the ring. This type of situation may cost you two or three hours to take out the finished product.
If the processing cycle is too long, the weak parts of the mold core may be broken due to the shrinkage of the rubber.
Of course, you can't predict all the problems that may occur in the trial mold process, but full consideration and timely measures can help you avoid serious and expensive losses.
Three, the main steps of the trial parts
In order to avoid unnecessary waste of time and troubles in mass production, it is necessary to pay patience to adjust and control various processing conditions, find the best temperature and pressure conditions, and formulate standard test procedures, which can be used in Establish daily working methods.
