Abstract

The invention discloses an injection mold ejection mechanism. The ejection mechanism is mounted on an injection mold and comprises a connecting plate, a large inclined ejector, a small inclined ejector, a return ejector rod and a nitrogen spring, wherein the connecting plate is positioned in a first groove, and the thickness of the connecting plate is smaller than the depth of the first groove; the upper end of the large inclined ejector is fixed at one end of the connecting plate, and the large inclined ejector penetrates through a cavity insert; the upper end of the small inclined ejector isfixed at the other end of the connecting plate, and the small inclined ejector penetrates through the cavity insert; the upper end of the return ejector rod is fixed in the middle of the connecting plate, and the return ejector rod penetrates through the cavity insert; and the upper end of the nitrogen spring is fixed in a second groove, and the lower end of the nitrogen spring is propped againstthe upper end of the large inclined ejector. Compared with the prior art, the connecting plate is arranged in a cavity plate, a cavity ejection plate is not required to be added between the cavity plate and a hot runner plate, the overall thickness of the injection mold is reduced, the overall weight is reduced, and the manufacturing cost is saved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold ejection mechanism. Background technique [0002] Injection molding machine is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using injection molds. After the plastic part is produced by the injection mold, it is necessary to use an ejector mechanism to demould the produced plastic part. In the prior art, a cavity top plate is arranged between the hot runner plate and the cavity plate, and the upper ends of the retraction rod, the large inclined top and the small inclined top are fixed on the cavity top plate. The disadvantage of this ejection mechanism is that it will increase the overall thickness of the injection mold and increase the overall weight. Therefore, how to provide an injection mold ejection mechanism for reducing the overall thickness and overall weight of the inject...
