After the well body steel mold is opened, the demoulding mechanism composed of the ejector pin and the ejector tube pushes out the plastic part from the driven model core. When the mold is closed, the movable mold moves forward and the reset rod resets the ejector mechanism to complete an injection molding cycle. In order to ensure the injection Molding quality must control the temperature of the hot runner plate and the temperature of the mold. Otherwise, if the temperature of the hot runner plate is too high, it will cause the plastic melt to decompose and affect the quality of the plastic parts. The gating system of the well body steel mold adopts a hot runner plate, which greatly improves the fluidity of the material, reduces the injection pressure required for injection molding, and ensures the quality of the product. In addition, the molding cycle has been shortened, a large amount of plastic raw materials have been saved, recycled materials have been reduced, and the automated production control process has been fully realized. The mold has been operating normally since it was put into production, creating considerable economic benefits for the company.
