Injection molding method for middle sundries box

Abstract

The invention discloses an injection molding method for a middle sundries box. The method is characterized by comprising the following specific steps that (1) injection molding equipment is checked firstly; (2) mold mounting is conducted, and after mold mounting is finished, the two-time adjustment process is further conducted to enable the injection molding equipment to enter an automatic mold adjusting state; (3) injection is conducted; (4) injection is finished, cooling molding is conducted, a product is made to be in a pressure maintaining stage, the pressure is maintained to be 60-80 bar, the time is 1-3 S, then the product is cooled, and the cooling time is 1-4 S; and (5) a mold is opened, and after cooling, only the mold needs to be opened to take out the product. The invention provides the complete plastic injection using method. The method is detailed in step and comprehensive in consideration; meanwhile after molding mounting is finished, the two-time adjustment process is further conducted to enable the injection molding equipment to enter the automatic mold adjusting state; and specific steps are given, operation errors are reduced, the product quality is indirectly ensured, and the product qualification rate is increased.

[0002] The central glove box of the car is installed in the cab of the car. It is mainly used to provide the people in the car with some items that are not easy to carry, small and must be used. Generally, most of them are directly molded by plastic; injection molding machines are made of plastic machinery. One, referred to as injection machine or injection molding machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Injection molding is achieved through injection molding machines and molds. The quality of the product, the steps of mold loading are very important. In the existing technology, most of the molds are directly loaded. After the mold loading is completed, the positions, pressures and speeds of the switch molds are set, and no adjustments are made again, and the automatic mold adjustment state is entered. , and there are many precautions in the entire injection molding process, which are often not noticed, resulting in certain errors and resulting in waste products
