A mold opening auxiliary ejection structure

Abstract

The invention discloses a mold opening auxiliary ejection structure which comprises a mold body, an ejector pin plate and a bottom plate. The ejector pin plate and the bottom plate are sequentially arranged on one side of the mold body, a through groove is formed in the ejector pin plate, a swing block is arranged in the through groove, one end of the bottom of the swing block extends downwards toform a first supporting foot, the other end of the bottom of the swing block extends downwards to form a second supporting foot, a first cushion block is arranged in the ejector pin plate, a second cushion block is arranged on the bottom plate, the swing block is rotationally installed on the ejector pin plate and tends to overturn towards the second cushion block, a straight ejector pin and an inclined ejector pin are arranged in the mold body, the bottom of the straight ejector pin is connected with the upper end of the swing block, the straight ejector pin and the first cushion block are located at the same end of the swing block, and the bottom of the inclined ejector pin is connected with the ejector pin plate. The mold opening auxiliary ejection structure provided by the invention is simple in structure, can eject out and demould a product and facilitates object taking by a manipulator.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a mold opening auxiliary ejection structure. Background technique [0002] Undercut refers to the structure of flanges, hooks or ribs in which the direction of core pulling and demoulding intersects with the opening and closing direction of the mold in injection molded products; The other side is called the inner side; according to the position, the undercut is divided into two types: the outer undercut and the inner undercut. An undercut whose depth or length is greater than three times the wall thickness of the product is called a deep undercut, and a deep undercut located inside the product is referred to as an inner deep undercut. [0003] In the actual mass production of injection molded parts with inner deep undercuts and high appearance requirements, since the product has to be held on the inclined roof, if the product is picked up directly by the robot, it will cause damag...

AI Technical Summary

Problems solved by technology

[0003] In the actual mass production of injection molded parts with inner deep undercuts and high appearance requirements, since the product has to be held on the inclined roof, if the product is picked up directly by the robot, it will cause damage to the product, and the defective rate of the product is 40%. Above, it must be picked up manually, which leads to time-consuming and labor-intensive processing, and also increases the cost
