Ejection structure of bumper unhooking cover plate in injection mold

Abstract

According to the technical scheme, the ejection structure of the bumper unhooking cover plate in the injection mold comprises a mold core plate, an ejection rod panel, an ejection rod bottom plate, an ejection oil cylinder and a movable mold fixing plate, the ejection rod panel and the ejection rod bottom plate are connected together, the ejection oil cylinder is connected to the ejection rod panel through an oil cylinder rod, and the movable mold fixing plate is connected to the ejection rod panel through an oil cylinder rod. An inclined ejector block and a straight ejector block are arranged at the positions, corresponding to a small arrowhead of a product, of the core plate, the inclined ejector block is located on the upper surface of the small arrowhead of the product, the straight ejector block is located on the lower surface of the small arrowhead of the product, and the lower portion of the inclined ejector block penetrates through the core plate through an inclined ejector rod and then is connected to the ejector rod face plate and the ejector rod bottom plate. The lower portion of the straight ejector block penetrates through the core plate through a straight ejector rod and then is connected to the ejector rod face plate and the ejector rod bottom plate, the ejector rod face plate and the ejector rod bottom plate are further provided with an ejector rod and a flat ejector rod, and the ejector rod and the flat ejector rod penetrate out of the core plate and then are located on the lower surface of a product. The straight ejection block and the inclined ejection block are matched at the small arrow of the product for ejection, so that the small arrow is prevented from being deformed when the product is ejected.

Description

technical field [0001] The invention relates to an injection mold, in particular to an ejection structure of a bumper decoupling cover plate in the injection mold. Background technique [0002] The product features of the bumper decoupling cover are simple, and the product structure is as follows: figure 1 As shown, but the side of the product contains a small arrow-shaped structure, and the width of the small arrow is about 2mm. Conventionally, the small arrow part is designed with a ejector pin for ejection and demoulding, but because the small arrow is small, the size of the ejector pin is very small (Φ1. 5mm), so the ejection force is small and the small arrow is easily deformed when it is demoulded. Contents of the invention [0003] In order to solve the above problems, the present invention provides an ejection structure for a bumper decoupling cover plate in an injection mold. [0004] The technical solution of the present invention is a bumper decoupling cover p...
