Injection mold with deformed mold core

Abstract

The invention discloses an injection mold with deformed mold core. A hydraulic stress plate is connected to the side end of a supporting sliding column, one end of the hydraulic stress plate is connected to a movable mold through a connecting screw rod, a fixed mold is installed at the side end of the supporting sliding column, an inner mold core penetrates through one end of the movable mold, anouter mold core penetrates through one end of the movable mold, a lower rack is welded to one end of the inner mold core, an upper rack is welded to one end of the outer mold core, a connecting gear is arranged between the lower rack and the upper rack in a meshed mode, a heat exchange box is connected to one end of the inner mold core, a push rod is welded to one end of the heat exchange box, theouter side of the push rod is sleeved with a reset spring, the mold core is driven by the rack to move, a size of an inner cavity is changed by changing the inner mold core, when injection molding needs to be conducted on a sleeve part, production can be conducted through a single mold, repeated operation by personnel is not needed, meanwhile, the production time of the sleeve part is shortened,and meanwhile the labor intensity of workers is relieved while the production efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an injection mold with deformed mold core. Background technique [0002] Mold refers to various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. It mainly realizes the object by changing the physical state of the formed material Shape processing, injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die-casting method. [0003] But at present, when casting kits, it is generally to make small internal parts through one mold and place them on another mold to produce large parts. During the production process, manpower is required to take and fix them, which greatly affects th...

Problems solved by technology

[0004] The present invention provides an injection mold with mold core deformation, which can effectively solve the above-mentioned background technology. At present, when casting a kit, generally a small internal part is made by one mold and then placed on another mold to produce a large one. Manpower is required to pick and fix the kit during the process, which greatly affects the production efficiency of the kit. At the same time, when some kits are produced, the inside and outside need to be bonded and fixed, so the kit needs to be reheated, which is easy to cause the kit product quality problems
