Inquire

Pre-inspection of injection mold

Before the mold is installed in the injection molding machine, it should be inspected to detect quality problems in time. Then modify the injection mold to avoid disassembly after installation. When inspecting the injection mold fixing plate and movable platen separately, pay attention to the direction marks to avoid errors when clamping the mold.

Installation of inclined guide die

When installing the mold, the two should cooperate closely and safely. If there is a mold for the lateral separation mechanism, the slider should be installed in a horizontal position, that is, the movable block is moved left and right.

Injection mold fixing

After the mold positioning ring is installed in the positioning ring seat of the injection molding machine fixed template, the mold is closed at a very slow speed so that the movable platen presses the mold gently, and then the platen is used. The pressure plate must be equipped with a backing plate, and four must be installed up and down. When using the pressure plate, be sure to adjust the height of the screw to the same height as the die foot, that is, the pressure plate should be flat. If the pressure plate is inclined, the die foot cannot be pressed tightly. The side of the platen will not be close to the mold to avoid damage to the mold due to friction.

Correct ejection distance of ejector

After fixing the injection mold, slowly start the mold until the movable platen stops and retracts. At this time, the position of the ejector should be adjusted to the position between the ejector plate and the movable platen on the mold. The gap is not less than 5mm. It is to prevent damage to the injection mold and to eject the injection molded part.

Adjustment of closed mold tightness

In order to prevent overflow, and also to ensure that the cavity is properly ventilated, when adjusting the clamping mechanism of the hydraulic injection, it is mainly based on visual observation and experience, that is, when the mold is closed, the elbow is fast first and then slow. This is not very natural, and it is not too reluctant to straighten out. The tightness of the mold is just right. For molds with mold temperature requirements, the mold tightness should be corrected after increasing the mold temperature.

Get cooling water

After connecting the cooling water, check whether the cooling water is free or leaking.
