A demolding and ejection structure for box-shaped products

Abstract

This utility model discloses a demolding and ejection structure for box-shaped products, including a rear mold B plate with a rear mold core in the middle area; a push plate disposed on the rear mold B plate, the push plate having a hollowed-out area in the middle, the rear mold core being located within the hollowed-out area and abutting against the peripheral wall of the hollowed-out area; and a hydraulic cylinder having a cylinder body and a drive end, the cylinder body being fixedly mounted on the rear mold B plate, and the drive end being connected to the push plate; after the box-shaped product is formed, the folded edge at the bottom of the box-shaped product abuts against the upper surface of the push plate; during demolding, the hydraulic cylinder drives the push plate to act on the folded edge of the box-shaped product, ejecting the box-shaped product from the rear mold core; by using a hydraulic cylinder to drive a whole push plate to perform lifting and lowering movements, the box-shaped product is ejected from the rear mold core in a balanced manner during demolding, effectively solving the problem of damage caused by uneven ejection of the box-shaped product.
