Mold design and manufacturing are closely related to plastic processing. The success or failure of plastic processing depends to a large extent on the mold design effect and mold manufacturing quality, while the plastic mold design is based on the correct plastic product design.
The structural elements to be considered in the design of plastic molds are:
(1) Parting surface, that is, the contact surface where the die and the punch cooperate with each other when the mold is closed. The choice of its position and form is influenced by factors such as product shape and appearance, wall thickness, forming method, post-processing process, mold type and structure, demolding method and molding machine structure.
(2) Structural parts, that is, sliders, inclined tops, straight top blocks, etc. of complex molds. The design of the structural parts is very critical, related to the life of the mold, processing cycle, cost, product quality and so on. Therefore, designing a complex mold core structure requires a higher level of comprehensive ability of the designer, and pursues a design that is simpler, more durable, and more economical.
