Product Description

Plastic injection molding equipment, also known as plastic injection molding machine, is a device that makes various types of plastic raw materials into desired products or preforms.

Plastic Injection Molding Equipment

What problems will occur in the adjustment part of plastic injection molding equipment? How should the problem be handled?


1. Plastic injection molding equipment cannot be adjusted

①. The mechanical level and parallelism are out of tolerance. Check with a spirit level angle ruler. Adjust the parallelism and level. (against

Large models, small models have little effect)

②. The gap between the pressure plate and the die-adjusting nut is too small. Measure with feeler gauge. Adjust the gap between the pressure plate and the nut, adjust the mold nut

Clearance with pressure plate (clearance≤0.05mm).

③. Burning the nut: Check whether the nut can be turned to generate heat and iron powder is coming out. Replace the nut.

④. Adjust the upper and lower support plates. Remove the lock nut of the expense board to check. Adjust the adjusting nut.

⑤. The I/O board is broken. Check whether there is a signal at the output point on the computer page. Repair the electronic board.

⑥. The mold adjustment spool is stuck. Remove the valve and check. Clean the valve.

⑦. Die adjustment motor is broken: check the oil motor. Replace or repair the oil motor.


In addition, when the plastic injection molding equipment is taking parts for injection molding, the safety door switch may not be closed smoothly, and the semi-automatic operation of the plastic injection molding equipment may fail.

Plastic Injection Molding Equipment

The principle of semi-automatic operation is: when the safety door is opened, the travel switch is closed, the machine sends a signal to start the semi-automatic action, and then the mold is closed. After the travel switch is touched, the mold is closed and the injection starts at the same time; the injection time relay starts timing and the injection time is up After that, the pre-molding starts, and when it touches the limit switch that has finished pre-molding, it starts to prevent flow. When it touches the anti-flow limit switch, the cooling time relay starts timing, and when the time is up, it will open the mold; After the mold terminates the stroke switch, perform the ejection action. After the ejection termination stroke switch is touched, the ejection action is performed. After the ejection termination stroke is encountered, the safety door is waited for opening.


In this way, work over and over again. It can be seen from the above that if the manual operation is normal, it is usually caused by the trip switch and time relay not sending a signal. According to the failure of the semi-automatic action in the mechanical cycle, compare the electrical appliances and hydraulic schematic diagrams to find out the corresponding control components, and check to solve them.

In short, more than 70% of the problems that occur in the production process of plastic injection molding equipment are generally caused by the injection molding process and the adjustment and control of the plastic machine. As long as the technical level of the plastic injection equipment production operators continues to improve, the With a deeper understanding of performance, many problems can be solved.
