Abstract

The invention discloses a secondary ejection mechanism. The mechanism comprises a fixing plate, an upper ejector plate, a lower ejector plate, a moving mould core, a connection rod fixedly arranged between the upper ejector plate and the lower ejector plate, and an ejector pin fixed on the lower ejector plate; the bottom of the connection rod is a connection rod seat, a plunger is arranged in the connection rod seat to radically fix the connection rod, the upper end of the connection rod is connected to an ejector block; a slide cavity is arranged in the moving mould core, a positioning mechanism is arranged on the ejector block, and the positioning mechanism can position the ejector block after the ejector block is ejected to slide in the slide cavity for the first time. Compared to the conventional secondary ejection mechanism, the secondary ejection mechanism has the advantages of simple structure, space saving, low cost, and strong reliability. Moreover, the secondary ejection mechanism well solves the problem of inadequate space, thus greatly enlarge the application range of the secondary ejection mechanism in plastic moulds, and the reliability and continuous production ability of mould are greatly improved.

Description

technical field [0001] The invention relates to a mold, in particular to a simple and space-saving secondary ejection mechanism. Background technique [0002] For plastic injection molds, the secondary ejection mechanism is widely used in many occasions. Most of the secondary ejection mechanisms have complex structures, and many auxiliary parts need to be added on the basis of the standard mold structure, which increases the cost of the mold. [0003] At the same time, limited by product size and structure, in many occasions, the secondary ejection mechanism cannot be implemented due to insufficient space. Therefore, it is necessary to design a simple and space-saving secondary ejection mechanism to solve this problem. Contents of the invention [0004] The technical problem to be solved by the present invention is to solve the problem of complex structure of the secondary top mechanism of the existing mold, and provide a simple secondary ejection mechanism. [0005] In ...
