Plastic mold design issues to be considered

Plastic mould, plastic processing industry and plastic molding machine supporting, giving plastic products in order to complete configuration and the exact size of the tool. Because many plastic varieties and processing methods, structural plastic moulding machine and plastic products and Traditional and Simplified different, so the type and structure of the plastic mould is varied. Plastic mould is a tool for the production of plastic products which parts parts by several groups, this combination successful mold cavity. When injection moulding, the injection moulding machine mold clamping, the molten plastic is injected into the mold cavity, and cooled in the cavity shape, and then the upper and lower split mold through the top of the article from the mold will leave the top of the mold cavity, the mold is closed again and finally for the next injection, the whole cycle of the injection molding process is carried out. Precision plastic mold design needs to consider the following questions:
1 understand the plastic melt flow behavior, consider the plastic resistance in the flow channel and the cavity of each flow, flow rate, parity maximum flow length. According to plastic flow direction in the mould (ie filling the order), consider the plastic in the mould re-fusing the inner cavity of the original air and export problems.
2 Consider plastic shrink during cooling and feeding problems.
Adoption of plastic mould design to control crystallization in the mold. Orientation and improve internal stress products.
4 Select the problems pouring into parting
Lateral type 5 and the top parts of the core pulling out of the question.
Cooling or heating problems 6. mold.
7 related to the size of the relationship between mold injection machine with the relationship, including the maximum injection volume and injection machines. Clamping force. Dimensions Die parts, etc..
8 Die overall structure and shape of the part to be simple and reasonable, the mold should have the appropriate accuracy. Finish. Strength and stiffness, easy to manufacture and assemble
With the rapid development of plastics and plastic moulding industry, plastic mould also emerged at this time, and now for the quality requirements of the plastic moulds are also increasing, which is the development of plastic mould industry offers tremendous momentum. Restructuring plastic mold industry continues to accelerate, market-oriented professional manufacturer of plastic mould number and ability to grow very fast. According to the production, sales, market conditions, industry structure, product import and export, etc. plastic mold manufacturing industry analysis, reference plastic mold-related industry trends, future development of plastic mould manufacturing industry is very broad.
