Plastic Injection Food Box Mould The basic structure of the plastic lunch box mold: Plastic parts are produced by injection molding. Therefore, the designed mold must have higher injection molding. The product is designed for mass production efficiency, and the pouring system must be able to automatically demould, and the point gate automatic demoulding structure can be adopted. Because the shape of the plastic part is relatively simple and the quality is small, mass production is required. The gate type adopts point gate feeding, so that the mold size is small, the manufacturing and processing are convenient, and it is conducive to filling the cavity, the quality of the plastic part is high, and the production efficiency is high. , The cost of plastic parts is low. Points for Attention in Mold Manufacturing: Need to choose the appropriate product specifications and shapes: the current shapes on the market include round and rectangular shapes, and the conventional capacities are 500ml, 750ml, and 1000ml. The rounded products are slightly lighter than the square ones. Mold material selection: Because the product wall thickness of thin-walled molds is only 0.4-0.8mm, the mold needs to withstand high pressure, so thin-walled molds need high-hardness steel materials to prevent mold deformation under long-term high-speed and high-pressure, resulting in flashing of the product , Increase costs and other issues. Mold design: product parting surface, product wall thickness design, mold exhaust design, mold waterway design, mold blowing position and direction design, these issues directly determine the success or failure of a thin-walled mold.
