Abstract

The present application discloses a mold for molding car door trims, which includes a fixed template and a movable template. There is a cavity for molding car door trims between the fixed template and the movable template. A combined core-pulling mechanism is provided on the rear side, and the combined core-pulling mechanism includes a forming slider, a first core-pulling assembly, a second core-pulling assembly and a third core-pulling assembly; On the movable template, the front end of the molding slider extends to the cavity, and the movable template is provided with a first linear drive device for driving the sliding of the molding slider; the first core-pulling assembly is arranged on the In the molding slider, the first core-pulling component passes through the molding slider and is suitable for forming an installation cavity and a slot. When the mold is opened, the fixed plate is suitable for driving the first core-pulling component to move and from The core is pulled in the card slot. It has the advantages of compact structure, smooth demoulding and low cost.

Description

technical field [0001] The application relates to the field of moulds, in particular to molding molds for automotive trims. Background technique [0002] Such as figure 1 Shown is a door trim 100, which is molded by injection molding. The difficulty of injection molding lies in the demoulding of multiple cavities with different orientations and deep holes on the trim. Specifically: the door trim 100 has an installation cavity 101 for installing the window button, and both sides of the bottom of the installation cavity 101 are also provided with draw-in slots 102; Mounting holes 103 and second mounting holes 104; the side of the door trim 100 is recessed toward the inside and provided with a plurality of relief through holes 105; the side of the door trim 100 is also protrudingly provided with two mounting posts for fixing 106 , the mounting column 106 is provided with a fixing hole 107 . Since the orientations of the above parts are not completely consistent, the mold can...
