        塑料模具制造需要注意什么 ?

        Jinan injection molding plastic mold manufacturing should pay attention to the following elements:
        1. Parting surface, that is, the contact surface between the female die and the male die when the die is closed. The selection of its position and form is affected by factors such as product shape and appearance, wall thickness, forming method, post-processing technology, mold type and structure, demoulding method and molding machine structure.
        2. Structural parts, i.e. sliding block, inclined top, straight top block, etc. of complex mold. The design of structural parts is very critical, which is related to the service life, processing cycle, cost and product quality of the die. Therefore, the design of complex die core structure requires higher comprehensive ability of the designer, and pursues a simpler, more durable and more economical design scheme as far as possible.
        3. Die accuracy, i.e. card avoidance, fine positioning, guide post, positioning pin, etc. The positioning system is related to the appearance quality of products, mold quality and service life. Different positioning methods are selected according to different mold structures. The positioning accuracy control mainly depends on processing, and the internal mold positioning is mainly considered by the designer to design a more reasonable and easy to adjust positioning method.
        4. Gating system, that is, the feeding channel from the nozzle of the injection molding machine to the mold cavity, including main flow channel, shunt channel, gate and cold material cavity. In particular, the selection of gate position should be conducive to filling the mold cavity with molten plastic under good flow state, and the solid runner and gate cold material attached to the product are easy to be ejected from the mold and removed during mold opening (except hot runner mold).
        5. Plastic shrinkage and various factors affecting the dimensional accuracy of products, such as mold manufacturing and assembly errors, mold wear, etc. In addition, the structure and molding parameters of the injection molding machine should be considered in the design of the injection molding machine. Computer aided design technology has been widely used in plastic mold design.
