Pre-pressing device for automobile interior injection molding part machining

The utility model relates to the technical field of injection molding part processing, in particular to a pre-pressing device for processing an automobile interior injection molding part, and solves the problems that in the prior art, the injection molding part is extruded from one direction in processing and pre-pressing, so that the extrusion force is not enough, the pre-pressing of a material is not in place, the subsequent processing speed is influenced, and the production cost is reduced. And inconvenience is caused. A pre-pressing device for automobile interior injection molding part machining comprises a box body, the upper portion and the lower portion of the inner side of the box body are both slidably connected with pressing plates, the upper portion and the lower portion of one side of the outer wall of the box body are both fixedly connected with side plates, and the top of one of the two side plates is fixedly connected with a driving motor through a bolt; and a two-way screw rod is rotationally
