2024-06-27


Injection molds can be divided into parting surfaces, structural parts, mold accuracy, mold accuracy, gating system, plastic shrinkage and factors affecting product dimensional accuracy, let's take a look!
1. Parting surface: that is, the contact surface between the injection mold and the punch when it is closed. The choice of its position and form is influenced by factors such as product shape and appearance, wall thickness, forming method, post-treatment process, mold type and structure, demoulding method and forming machine structure.
2. Structural parts: that is, the slider, inclined top and straight top of the complex mold. The design of structural parts is very critical, which is related to the life of the product, processing cycle, cost, product quality, etc. Therefore, the design of complex mold core structure requires the comprehensive ability of the designer, and tries his best to pursue a simpler, more durable and more economical design scheme.
3. Mold accuracy: i.e., card avoidance, precision positioning, guide pillar, positioning pin, etc. The positioning system is related to the appearance quality of the product, the quality of the mold and the life of the mold. According to the different mold structure, different positioning methods are selected. The control of positioning accuracy depends mainly on the handling. The positioning of the inner mold is mainly considered by the designer, and a more reasonable and easy-to-adjust positioning method is designed.
