Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The lateral ejection mechanism of the injection mold comprises a bottom plate 8 and is characterized in that two mold feet 7 are symmetrically arranged on two sides above the bottom plate 8.

A lower ejector plate 10 is arranged between the two mould feet 7, an upper ejector plate 9 is arranged above the lower ejector plate 10, and the lower ejector plate 10 is fixed with the upper ejector plate 9 through bolts.

A step hole is formed in the lower ejector plate 10, a first through hole is formed in the upper ejector plate 9, and the center line of the first through hole is overlapped with the center line of the step hole.

A rotating shaft 5 and a base 4 are arranged in the lower ejector plate 10, one end of the rotating shaft 5 and one end of the base 4 are arranged in the step hole, and the other end of the rotating shaft 5 and the base 4 are arranged in the first through hole.

The rotating shaft 5 is arranged in the base 4 of the rotating shaft 5, the second through hole is arranged in the middle of the bottom plate 8, the bottom of the base 4 of the rotating shaft 5 is provided with three through holes, and the second through hole corresponds to the third through hole.

The rotating shaft 5 is fixedly provided with the elastic ejector 3, the top of the elastic ejector 3 is matched with the bottom surface of the plastic part, and the bolt penetrates through the third through hole to be connected with the elastic ejector 3.
