Mold plates are crucial components of various molds. An important issue in mold manufacturing is how to manufacture plate-type parts to meet the requirements of mold structure, shape, and molding functions, achieve the required manufacturing precision and performance, and obtain higher economic benefits.
The shape, size, and precision grade of mold plate – type parts have different requirements, but their roles can be summarized in the following aspects.
(1) Connection Function
The moving and fixed mold plates in injection molds serve to connect other parts of the mold, ensuring that the injection mold has the correct relative position during operation. At the same time, they also play a role in connecting with the equipment used.
(2) Positioning Function
The moving and fixed mold clamping plates in injection molds are used to position the relative positions of the moving and fixed molds, ensuring the accuracy of their relative positions during the injection molding process.
(3) Guiding Function
Mold plate – type parts cooperate with guide pillars and guide bushes. During the operation of the injection mold, they move back and forth in a straight line along the mold opening and closing direction. They guide the movement direction of all parts in the injection mold.
(4) Ejecting and Unloading Functions
After the injection mold completes a molding process, the stripper plate, ejector plate, and ejector pin retaining plate promptly eject the molded plastic products or unload the blank materials with the help of the equipment’s power, so that the injection mold can smoothly proceed with the next product molding.
