(Summary description)1. Parting surface: the contact surface between the plastic mold and the convex mold when it is closed. The choice of its location 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 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, related to product life, processing cycle, cost, product quality, etc. Therefore, the design of the complex core structure requires the comprehensive ability of the designer, and strives to pursue a simpler, more durable, and more economical design solution.
3. Mold accuracy: namely avoiding jams, positioning, guide posts, positioning pins, etc. The positioning system is related to the appearance quality of the product, mold quality and mold life. According to the different mold structure, choose different positioning methods. The control of positioning accuracy mainly depends on processing. The positioning of the internal mold is mainly considered by the designer, and a more reasonable and easy-to-adjust positioning method is designed.
4. Pouring system: the feeding channel from the nozzle to the cavity of the injection molding machine, including the main runner, branch runner, gate and cold cavity. In particular, the selection of the gate position should be conducive to filling the cavity with molten plastic in a good flow state, and when the mold is opened (except for the hot runner mold), the solid runner and gate cold material attached to the product can be very effective. Easily eject and remove from the mold.
5. Plastic shrinkage rate and factors affecting product dimensional accuracy: such as plastic mold manufacturing and assembly errors, mold wear, etc. In addition, when designing compression molds and injection molds, the matching of process parameters and structural parameters of the molding machine should also be considered.
