[0002] In the field of plastic injection molding, the design and performance of the mold play a crucial role in the quality, production efficiency, and cost control of plastic products. The forming mold is usually composed of a male die and a female die. Through the opening and closing of the two and the coordinated operation of the internal structure, molten plastic is injected into the cavity, and the desired plastic product is obtained after cooling and solidification.
[0003] Traditional forming molds often face the problem of unbalanced ejection during the ejection of plastic products. After the plastic product is formed, it needs to be ejected from the mold cavity with the help of an ejection mechanism. However, due to the complexity of the mold structure and the diversity of product shapes, uneven force distribution often occurs during ejection. For example, for some plastic products with irregular shapes, uneven wall thickness, or internal undercut structures, if the resistance of each part of the mold is not consistent during ejection, some areas will be ejected first, while other areas will still be attached to the mold, causing product deformation, scratches, or even damage, which seriously affects the product's pass rate.
