Plastic mold design elements

- May 25, 2018 -

Mold design and manufacturing are closely related to plastics processing. The success or failure of plastics processing largely depends on the design of the mold and the quality of the mold. The plastic mold design is based on the correct design of plastic products.


The structural elements to be considered in plastic mold design are:

1 parting surface, that is, the contact surface where the die and punch cooperate with each other when the mold is closed. The choice of its position and form is influenced by factors such as the shape and appearance of the product, the wall thickness, the molding method, the post-processing technology, the type and structure of the mold, the demolding method, and the structure of the molding machine.


2 structural parts, that is, the complex mold slider, inclined roof, straight top block and so on. The design of structural parts is very critical, and it is related to the life of the mold, processing cycle, cost, product quality, etc. Therefore, designing a complex mold core structure has a higher requirement for the designer's comprehensive capabilities, and the pursuit of simpler, more durable, and more economical Design.
