Problems solved by technology

[0003] Existing molds generally use inclined guide rods to demould the fixed and movable modules, but for plastic parts with threads such as pipe joints, it is easy to demould the plastic parts only by moving the inclined guide rods. Causes damage to the internal thread of the molded plastic part, reduces the pass rate of the plastic part, and makes it difficult to demould the molded plastic part

Embodiment 1

[0038] like figure 1 As shown, the automatic demoulding injection mold includes a fixed module 1 and a moving module 2, and a molding cavity 3 is formed between the fixed module 1 and the moving module 2.

[0039] Specifically, if Figure 1-4 As shown, the injection mold also includes setting a demoulding pipe one 4, a slider core one 41, a demoulding pipe two 5 and a slider core two 51, and the demoulding pipe one 4 and the slider core one 41 are all arranged on At the two ends of the moving module 2, one end of the slide block core-41 passes through the demoulding pipe-4, and this end is connected with a demoulding slide block 42, and the stripping slide block 42 is provided with the slide block core-41 to move along the Axially moving reset piece, the demoulding slider 42 is provided with a mounting groove 43, and the mounting groove 43 is provided with a slave gear 1 45 and a master gear 44 that mesh with each other, and one end of the demoulding pipe 4 is sleeved on the ...

Embodiment 2

[0052] The injection mold for automatic demoulding of the present embodiment is basically the same as that of Embodiment 1, the difference being that the reset part is an elastic reset pull rod, one end of the elastic reset pull rod is connected with the demoulding slider 42, and the other end of the elastic reset pull rod is connected with The moving module 2 is connected.

[0053] The setting of this structure, after the mold demoulding is completed, by moving the inclined guide column 9, and closing the movable module 2 and the fixed module 1, the elastic force of the elastic reset rod can drive the demoulding slider 42 to move towards the movable module 2 , to realize the rapid reset of the mold, so that the demoulding efficiency of the mold is improved during the production process of the whole mold.

Abstract

The invention provides an injection mold capable of achieving automatic demolding, and belongs to the technical field of molds. The injection mold solves the problems that an existing pipe connector is difficult to demold, the demolding efficiency is low. The injection mold capable of achieving automatic demolding comprises a fixed module and a movable module, and further comprises a first demolding pipe, a first sliding block core, a second demolding pipe and a second sliding block core; a forming cavity is formed between the fixed module and the movable module; one end of the first sliding block core penetrates out of the first demolding pipe and is connected with a demolding sliding block; a mounting groove is formed in the demolding sliding block; a first slave gear and a second main gear which mesh with each other are arranged in the mounting groove; one end of the first demolding pipe is connected to the first slave gear in a sleeving mode; one end of the second demolding pipe and one end of the second sliding block core are connected to a gear fixing plate; a second slave gear and a second main gear which mesh with each other are arranged in the gear fixing plate; one end of the second demolding pipe is connected to the second slave gear in a sleeved mode; and a chain wheel capable of driving the main gears to rotate is connected to the second main gear. According to the injection mold capable of demolding automatically, stable demolding of the pipe connector can be realized.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to an injection mold for automatic demoulding. Background technique [0002] Injection mold is a tool for producing plastic products. Generally, injection mold is composed of a moving module and a fixed module. A molding cavity and a plastic runner system are formed between the fixed module and the moving module. During injection molding, the moving module and the fixed module are combined. The mold is clamped on the injection molding machine. At this time, the molten plastic flows into the runner system from the injection port and into the molding cavity, and is cooled and formed in the cavity. At the same time, the molten plastic is also cooled into a flow in the runner system. After the plastic part is formed, the movable module and the fixed module are opened and the plastic part is ejected from the cavity through the ejector system to leave the mold. When it needs to be injected a...
