Injection mold with adjustable mold core and using method thereof

Abstract

The invention discloses an injection mold with an adjustable core, which comprises a back mold bottom plate, a front mold bottom plate, a front mold core, a rear mold core and a movable connecting plate, the rear mold bottom plate is fixedly installed on the lower part of the front mold bottom plate, and the rear Two sets of supporting square irons are fixedly installed on the outer surface of the upper end of the mold bottom plate, a front formwork is fixedly installed on the outer surface of the lower end of the front mold base, and a rear formwork is fixedly installed on the outer surface of the lower end of the front mold base. The square iron and the rear formwork are docked and fixed by four sets of thimble guide pillars, and four sets of positioning guide pillars are installed through the inner side of the front formwork; an injection mold with an adjustable core of the present invention makes the injection mold have The mold core adjustment structure can flexibly adjust the distance between the two sets of mold cores, making its use and operation more flexible, and at the same time prolonging the service life of the mold core operation, making the butt joint operation of the guide post of the injection mold more convenient, and convenient for users to carry out. It is more practical to plug and unplug the fixed operation.

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.
