Abstract

The invention discloses an injection mould. The injection mould comprises an ejection system, a rear template and a rear mould insert arranged in the rear template and also comprises a base plate, wherein the base plate is fixedly arranged on the ejection system, the rear mould insert is fixed at the base plate, the rear template is arranged on the base plate, and a control member used for controlling the rear template to move far away from the base plate when the mould is opened is arranged between the rear template and the base plate. According to the injection mould disclosed by the invention, the base plate is additionally arranged, and the rear template is changed into a float plate form, so that a deep rib circle glue position of an injection part is drawn out firstly before a product is ejected, the ejection is smooth by utilizing the action, the quality of the injection part is stable, and the injection part can be ensured to be intactly separated from a rear mould assembly.

Description

Technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an injection mold. Background technique [0002] In modern mechanical transmission, a pressure lubrication system is often used to provide the necessary lubrication conditions for the transmission mechanism to ensure the normal operation of the transmission mechanism. [0003] The injection molded parts are left in the back mold too high and the circumference has deep ribs, and the packing force is large. During the reproduction process, the product is prone to deformation and damage when the product is ejected. [0004] Therefore, how to ensure that the injection molded part is completely separated from the rear mold assembly is a technical problem that needs to be solved by those skilled in the art. Summary of the invention [0005] In view of this, the purpose of the present invention is to provide an injection mold that can ensure that the injection molded part is comple...
