Safety ejection mechanism for injection mould

Abstract

The invention discloses a safety ejection mechanism for an injection mould; the safety ejection mechanism for the injection mould comprises an ejector pin plate, an ejector pin fixing plate, an ejector pin, a safety ejector pin and a lateral core pulling mechanism arranged at the upper end of the safety ejector pin; the ejector pin fixing plate is arranged on the upper surface of the ejector pin plate; the ejector pin and the safety ejector pin are fixed on the upper surface of the ejector pin plate by the ejector pin fixing plate; the lateral core pulling mechanism comprises a lateral pulled core, a reset spring and a pressure block, wherein the reset spring is arranged at one end of the lateral pulled core; the pressure block is arranged at the upper side of the lateral pulled core and mutually matched with the lateral pulled core; and a safety hole matched with the safety ejector pin is formed in the lateral pulled core. The safety ejection mechanism for the injection mould, disclosed by the invention, has the specific advantages of being reasonable in design, simple in structure, high in safety performance, low in cost and long in service life; in addition, after injection molding, the ejector pin and the lateral pulled core cannot be interfered with each other when an injection product is ejected by the ejector pin.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a safety ejection mechanism for injection molds. [0002] Background technique [0003] At present, during the injection molding process of injection molded products, after the injection molding of the injection molded product is completed, an ejector pin is required to push the injection molded product out of the male mold, and because some injection molded products have undercuts, side pumping is required during the injection molding process core mechanism to complete. [0004] However, in the prior art, the side core-pulling mechanism and the ejection mechanism often interfere with each other. For example, when the side core-pulling has not been completely drawn out of the injection molded product, the ejection mechanism starts to eject the injection molded product, and in this process, it is extremely difficult. It is easy to break the thimble and damage the side co...

[0004] However, the side core-pulling mechanism and the ejection mechanism of the prior art often interfere with each other. For example, when the side core-pulling has not been completely drawn out from the injection molded product, the ejection mechanism starts to eject the injection molded product, and in this process, it is extremely difficult. It is easy to break the thimble and damage the side core, thus increasing the incidence of safety accidents in the injection mold production process
