Abstract

The invention relates to the technical field of injection molds, and relates to a secondary ejection structure and method of a crank slider of an injection mold, including a crank slider mechanism, a push plate for pushing a movable mold upward to eject a product to a first distance, Shifting block and thimble block; the slider crank mechanism includes a first connecting rod and a second connecting rod, one end of the first connecting rod is hinged with the base, the other end is hinged with one end of the second connecting rod through a hinge, and the other end of the second connecting rod is hinged. One end is hinged with the push plate; the hinge is slidable and located in the semi-crescent chute of the shifting block, the shifting block is fixedly connected with the thimble block, and the thimble block is fixed with a thimble for ejecting the product to the second distance. When the plastic product has a deep glue position on the movable mold side, the secondary ejection structure is simple and easy to realize product demoulding, and it has low cost, simple maintenance and high versatility. Achieve secondary ejection with fewer parts added. The processing and assembly of the added parts are easier. So as to achieve the effect of saving mold cost.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a secondary ejection structure of a crank slider of an injection mold. Background technique [0002] With the wide application of insert injection molds, the disadvantages of the original mode of manually placing inserts are becoming more and more prominent. In the industry, there are mold structures suitable for automatic placement of inserts, and the mold ejection system is to realize automation. The key is that in the technology of the same industry, after the injection mold ejects the insert product, the insert product remains in contact with the ejector pin in the ejection structure. Then, when the product moves horizontally with the material belt, it often The product is scratched or the thimble is broken, which greatly reduces the qualified rate of the product and increases the cost of mold maintenance. [0003] Due to the shape of the plastic part itself, the pro...
