Plastic trash can mold wheel connecting hole core-pulling mechanism, mainly including the upper plate and the lower plate of the mold, the fixed template is connected under the upper plate, the cavity insert is installed under the fixed template, and the movable template is installed on the lower plate. The upper mounting core insert, the core insert and the cavity insert form a cavity for forming the trash can. In order to form the caster hole at the bottom of the trash can, the core is installed on each of the outer walls of the cavity insert. The oil cylinder, the piston rod of each core cylinder is connected with the core rod, and the core rod is matched with the caster hole. Although the core rod structure can realize the formation of the caster hole, the large trash can has a large volume, in order to ensure the structure. Intensity, the injection molding at the caster hole is relatively thick. At this time, the inner wall of the hole is farther away from the cooling pipe, so the cooling speed is slower. When the core pulling rod is pulled out, the plastic is not completely cooled and easily adheres to the core pulling rod. Destruction in the hole, resulting in drawing, burrs and other phenomena.
