Abstract

The invention discloses an injection mold and a manufacturing method of the injection mold, and belongs to the technical field of injection molds, the injection mold comprises an upper mold base and a lower mold base, the upper mold base and the lower mold base are oppositely arranged, a base is fixedly mounted at the bottom of the lower mold base, and an ejector pin assembly mechanism is movably mounted in an inner cavity of the lower mold base; and a filling mechanism is movably mounted at the top of the ejector pin assembling mechanism. According to the invention, the outer side abutting block of the second assembly block can support the inner cavity of the second assembly groove after abutting against the inner cavity of the second assembly groove by means of the elastic force of the second assembly block, modular assembly of the ejector pin main body is realized through the ejector pin seat, and meanwhile, the ejector pin main body can be quickly adjusted at the relative axial position at the top of the ejector pin seat by cooperating with the second assembly block on the bottom side; adjustment and adaptation of ejection positions of injection mold cores in different shapes are met, injection molding discharging of products of different specifications is facilitated, the injection mold ejector pin replacement adjustment and maintenance difficulty can be effectively reduced, and the use requirement is met.

Description

technical field [0001] The invention belongs to the technical field of injection molds, in particular to an injection mold and a manufacturing method of the injection mold. Background technique [0002] In the injection molding of plastic products, it is necessary to use the injection mold for shaping and ejection cooling. The ejection of the transmission injection mold is generally realized through the ejector structure. The strength and installation position of the ejector pin determine the appearance of the joint with the product. aesthetics. [0003] Chinese patent document CN113021796A discloses an ejection device for an injection mold, including a workbench, four diagonal corners of the workbench are fixedly connected with support legs, and the tops of the four support legs are fixedly connected with the same top plate, the A drive motor is fixedly connected to the bottom of the workbench, a drive shaft is fixedly connected to the output end of the drive motor, and th...
