Abstract

The invention relates to the technical field of demolding of injection molded products and provides an ejection mechanism and an injection mold with the ejection mechanism. The ejection mechanism comprises a slide way arranged on a moving mold, a sliding seat arranged on a fixed mold and an ejector pin. The sliding way is provided with a boss. The sliding seat is provided with an insert pin and athrough hole parallel to the insert pin. The bottom end of the insert pin extends out of the through hole, and the top end of the ejector pin abuts against the molded surface of the formed product. The sliding seat is opposite to the front face of the slide way. The sliding seat can drive the bottom of the ejector pint to move along the slide way to the upper side of the boss. The ejection mechanism is applied to the injection mold, the sliding seat is used for driving the bottom of the ejector pin to move along the slide way to the upper side of the boss, the boss lifts up the ejector pin, the ejector pin ejects upwards the molded surface of the formed product, the formed product is disengaged from the insert pin, and the quality of a threaded rod and injection molded holes such an exhaust hole is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ejection of injection molded products, and more specifically relates to an ejection mechanism and an injection mold with the ejection mechanism. Background technique [0002] When injection molded products are opened, ejector pins are usually used to eject them. The automobile bumper housing is generally provided with screw posts, and the position of the screw posts is arranged relatively deep in the housing. It is inconvenient to directly place an ejector pin at the position of the screw column on the mold, so that the screw column on the housing cannot be ejected by the ejector pin. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ejector mechanism, in which an ejector pin is set in the mold for the position of the screw post, and the ejector device is used to drive the ejector pin to eject the screw post. [0004] The technical solution...
