Abstract

The invention discloses a double ejection mechanism. The double ejection mechanism comprises at least two ejector pin plates, an ejection mechanism and a spacing mechanism; the at least two ejector pin plates comprise an upper ejector pin plate group and a lower ejector pin plate group which are respectively fixed together; the ejection mechanism is connected below the upper ejector pin plate group; the spacing mechanism comprises a spacing column; the upper end of the spacing column is fixed on the lower ejector pin plate group, and slides upward so as to penetrate through the upper ejector pin plate group; the upper end of the spacing column is provided with a clamping table; an elastic element is arranged between the clamping table and the upper ejector pin plate group. The double ejection mechanism provided by the invention has the characteristics of high reliability, low assembling requirement, easiness in assembling and regulating and shortened acting time. The double ejection mechanism provided by the invention can be used for a large mold.

Description

technical field [0001] The invention relates to a secondary ejection mechanism applied to a mold. Background technique [0002] At present, when designing some products, it is necessary to use the mold to eject twice to facilitate demoulding. The existing secondary ejection mechanism uses the force of the shutter to keep the four top plates ejected together. When a certain distance is ejected, the limit column hits the male formwork to prevent the next two top plates from continuing to eject. However, the existing secondary ejection mechanism of the shutter has disadvantages such as easy wear, easy failure of ejection, and short ejection stroke. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] In order to solve the above problems, the present invention proposes a secondary ejector mechanism, comprising: at least two ejector plates, the at least two ejector plates are divided ...
