Description

Ejector pin structure of injection mold Technical Field The utility model belongs to the technical field of injection molds, and relates to a thimble structure of an injection mold. Background The injection mold is used for injecting molten plastic into a mold cavity, cooling and solidifying to obtain a finished product, and is suitable for mass production of plastic parts with complex geometric shapes and high precision requirements. After injection molding, when demolding is needed, ejection is carried out through the ejector pins, but the existing ejector pins have the following problems in assembly: Usually, tens or even hundreds of ejector pin pieces are required to be installed on an ejector pin plate of a mold, and types of ejector pins in different areas are different, so that the ejector pins are very complicated in assembly, and errors are easy to occur, and therefore, an ejector pin structure capable of improving assembly efficiency and accuracy is required to be arranged. Disclosure of Invention The utility model aims to provide a thimble structure of an injection mold, so as to solve the problems in the prior art. The aim of the utility model can be achieved by the following technical scheme: The utility model provides an injection mold's thimble structure, includes thimble board body, loading frame, telescopic link and removes the seat, two inside grooves have been seted up to the inside of thimble board body, the inside activity of inside groove is provided with removes the seat, the outside of removing the seat is provided with the mount pad, the internally mounted of mount pad has the fixed block, the one end of fixed block is connected with the round pin axle seat through the swing arm axle, just the one end activity of swing arm axle sets up in the inside of round pin axle seat, the bottom of round pin axle seat is connected with the support arm, the bottom of support arm is connected with the telescopic link, the bottom swing joint of telescopic link has the loading frame. In the ejector pin structure of the injection mold, the middle part in the inner groove is provided with the supporting wheel groove, the middle part of the movable seat is provided with the supporting roller, and the supporting roller slides in the supporting wheel groove. In the ejector pin structure of the injection mold, a plurality of ejector pin grooves are formed in two sides of the loading frame from top to bottom, and a magnetic attraction ring is arranged in each ejector pin groove. In the ejector pin structure of the injection mold, two fixing holes are formed in the fixing block, a positioning bolt is connected to the top end of the mounting seat in a threaded mode, and the bottom end of the positioning bolt is connected to the inside of the fixing hole in a threaded mode.
