Abstract
The present invention relates to an injection molding method of a door lock component, which includes the following steps: providing a primer with adhesive force above 90 kg/cm2 and heat resistance temperature above 200 degrees Celsius; dipping at least a portion of the surface of an electromagnet with the primer and then placing into a mold; thermally melting a predetermined insulation plastic encapsulation material and then injecting the melted plastic into the mold cavity by controlling the melted plastic injection temperature between 200 to 250 degrees Celsius; providing the mold with at least four runners, that is front, rear, left and right, and a gate, so that the melted plastic is injected into the mold cavity from the top peripheral of the electromagnet; and, controlling the injection pressure and time during the injection stage, so that the injection time is within 6 seconds, and the injection pressure is first set to be high, and lowered along various stages. The door lock component made by the injection molding method will have the bonding surface between metal and plastic not easily forming pores to provide a solid bonding without stripping or deformation, so as to improve the product reliability and economic benefits.
