Abstract

The invention relates to a large angle ejection mechanism for injection molding. The large angle ejection mechanism comprises an angle ejection body, wherein an ejector rod is arranged at the bottom end of the angle ejection body; a sliding chute is formed in the bottom end of the angle ejection body; a sliding block is arranged at the top end of the ejector rod, and is arranged in the sliding chute of the angle ejection body in a sliding mode; the bottom end of the ejector rod is fixedly connected with a mounting seat; the extension direction of the sliding chute is the horizontal direction, and the ejector rod is perpendicular to the extension direction of the sliding chute. A large angle ejection is divided into two parts, so that a large amount of manufacturing materials can be saved and thus the manufacturing cost is reduced. The large angle ejection mechanism is good in force transmission effect and smooth and steady in movement.

Description

Technical field [0001] The invention relates to an ejector mechanism in the field of injection molding, in particular to a large inclined ejector mechanism for injection molding. Background technique [0002] The inclined top of the mold is a mechanism used to form the internal barbs of the product in the mold design. When manufacturing some large injection molded parts with internal barbs, some large inclined roof mechanisms with relatively large volumes are required. Generally, the inclined roof is manufactured as a whole, so the material cost is very high when manufacturing the large inclined roof mechanism. And when making matching templates, oblique holes with a long stroke must be processed to adapt to large oblique tops. The above factors all lead to the high manufacturing cost of the large inclined roof mechanism. Summary of the invention [0003] The purpose of the present invention is to provide a large inclined top mechanism for injection molding with less manufactur...
