Description

Technical Field

[0001] The utility model relates to the field of injection molds, in particular to an automobile injection mold containing sheet metal parts. Background Art

[0002] An injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to the high-pressure injection of heated and melted plastic into the mold cavity by an injection molding machine, and after cooling and solidification, a molded product is obtained. The injection mold mainly includes a front mold and a rear mold. The front mold is installed on the fixed base plate of the injection molding machine, and the rear mold is installed on the movable base plate of the injection molding machine. During injection molding, the front and rear molds are closed, and the plastic enters the mold cavity through the nozzle. When opening the mold, the front and rear molds are separated, and then the ejector mechanism is activated to eject the injection molded part.

[0003] There are many injection molded products containing sheet metal parts in automobile parts. When injecting, the sheet metal parts need to be pre-set on the core before the mold is closed for injection molding. Since the limiting effect of the sheet metal parts in the mold is limited, the sheet metal parts may shift or tilt when the mold is closed, which not only leads to unstable product quality, but also may crush the sheet metal parts or even damage the mold, making the mold very unstable to use.
