Injection mold with adjustable mold cores and application method thereof

Abstract

The invention discloses an injection mold with adjustable mold cores. The injection mold with the adjustable mold cores comprises a rear mold base plate, a front mold base plate, the front mold core,the rear mold core and movable connecting plates. The rear mold base plate is fixedly installed at the bottom of the front mold base plate, and two sets of square supporting iron are fixedly installedon the outer surface of the upper end of the rear mold base plate. A front mold frame is fixedly installed on the outer surface of the lower end of the front mold base plate, and a rear mold frame isfixedly installed on the outer surface of the lower end of the front mold frame. The square supporting iron and the rear mold frame are connected in a butt joint mode and fixed through four ejector pin guide columns, and four locating guide columns are installed on the inner side of the front mold frame in a penetration mode. According to the injection mold with the adjustable mold cores, the injection mold can comprise a mold core adjusting structure, the separation distance between the two mold cores of the injection mold can be flexibly adjusted, the injection mold can be more flexible touse and operate, the operating service life of each mold core is prolonged, the guide column butt joint operation of the injection mold can be more convenient and faster, a user conveniently conductsinsertion and pull fixing operation on the injection mold, and the injection mold is relatively practical.

Description

technical field [0001] The invention belongs to the field of injection molds, and in particular relates to an adjustable injection mold, more specifically an injection mold with an adjustable core and a method for using the same. Background technique [0002] Injection molding is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] An injection mold disclosed in the reference document CN207789608U includes an upper mold and a lower mold; the upper mold is provided with a cylindrical upper mold core, and the upper mold core includes a core body and a support sleeved outside the core tu...

AI Technical Summary

Problems solved by technology

[0004] Existing injection molds have certain disadvantages in the use process. The core of the traditional injection mold adopts an integrated fixed structure design, which makes it impossible for users to adjust the use height of the core according to their own needs, which reduces the use of injection molds. The flexibility makes the shape of the module blank processed by the injection mold single, without the adjustment structure of the mold core; at the same time, the traditional injection mold does not have an auxiliary fixing structure, and it is impossible to limit and fix the mold core under the adjustment state, and it cannot be reduced. The friction force generated during the mold core adjustment operation; at the same time, traditional injection molds use traditional positioning guide pillars for docking and fixing operations, which increases the difficulty of positioning guide pillar installation and removal operations, and brings certain adverse effects to users.
