When processing plastic molds, precautions should be taken: 1. The shrinkage coefficient of each material is different, and the plastic mold should have a reasonable shrinkage force. The plastic mold should have sufficient stiffness, otherwise during mold closing and pressure maintaining, the product will deform or cause burrs during mold release. If the product is pressed against the top needle page of the injection molding machine while opening the mold, it can be set, but some injection molding machines do not have this function. Choose a reasonable multimode method, choose a reasonable top position, and ensure that the product is not damaged during the ejection process based on the quantity. The cooling time in the plastic mold is related to factors such as product size, shape, and plastic properties, as well as the holding time.
The plastic mold should choose a reasonable exhaust position and control the amount, otherwise it may cause dissatisfaction during plastic injection molding, resulting in product shortage of glue. The plastic mold and injection molding machine should be fixed in a reasonable and reliable manner to prevent accidents caused by displacement during mold closing. The above are the precautions to be taken in the production of plastic mold processing.
