What is a plastic mold? How to avoid plastic mold compression?

2022/11/04

Main uses of plastic molds: compression molding, extrusion molding, injection molding, blow molding

Plastic mold junction: concave mold combination substrate

Features of plastic mold: can process plastic parts of different shapes

Plastic mold is the abbreviation of a combined mold for compression molding, extrusion molding, injection molding, blow molding and low foam molding. The coordinated changes of the mold convex, concave mold and auxiliary molding system can process a series of plastic parts of different shapes and sizes.

Plastic molds are the mother of the industry, and now new product releases will involve plastics.

It mainly includes a concave die with variable cavity composed of a concave die combination substrate, a concave die assembly and a concave die combination card plate. A punch with a variable core composed of side-cut composite panels.

In order to improve the performance of plastics, various auxiliary materials, such as fillers, plasticizers, lubricants, stabilizers, colorants, etc., must be added to the polymer to become a plastic with good performance.

Install the equalizing mold protector to prevent the plastic mold from being pressed:

Mold protector, also known as mold monitor and electronic eye, is mainly a mold protection system that monitors, controls and detects the operation of various injection molding machines in real time.

It can effectively protect the expensive mold, can effectively detect whether the product is qualified, and check whether there is any residue before the mold is closed to prevent the mold from being pinched.

Working principle: When the injection molding machine opens the mold in place, the output signal triggers the mold protector, which continuously takes images of the mold cavity and monitors whether the ejector pin pushes out and falls the molded workpiece. When the workpiece is completely dropped, the mold monitor sends a confirmation signal back to the injection molding machine to start the next cycle.

If the workpiece does not fall or there is debris between the molds within the set time, the mold protector will send an abnormal signal to stop the injection molding machine and alarm.
