Embodiment Construction

[0040] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through a complete specific embodiment.

[0041] The injection mold of the tool internal thread disclosed by the present invention, such as Figure 1-6 As shown, it includes a first mold 1, a second mold 2 and a shaft 3, the second mold 2 is provided with a first through hole 21 matching the shaft 3, and the shaft 3 can rotate and slide through the Located in the first through hole 21, it can be set by a bearing. One end of the shaft 3 passes through the second mold 2 and is provided with a threaded core 31. The threaded core 31 is connected with the first mold 1 and the second mold. The molds 2 are combined to form the injection cavity 4 of the injection molded part. The first mold 1 or the second mold 2 is provided with an injection hole 5 leading to the injection cavity 4 , which is arranged on the first mold 1 in the figure. Let me ex...

Abstract

The invention discloses an injection mold with internal thread, which comprises a first mold, a second mold and a shaft, the second mold is provided with a first through hole matched with the shaft, and the shaft can rotate and Slidingly penetrated in the first through hole, one end of the shaft passes through the second mold and is provided with a threaded core, and the threaded core is combined with the first mold and the second mold to form the injection cavity of the injection molded part , the first mold or the second mold is provided with an injection hole leading to the injection molding cavity, the demoulding method of the mold can realize the automatic core pulling of the threaded core, and the first mold includes a first outer plate , a convex module and a stripping module, a separation structure is provided between the first outer plate and the stripping module, through which the automatic demoulding of injection molded parts can be realized, and the demoulding efficiency of injection molded parts with internal threads can be greatly improved.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an injection mold with internal threads and a demoulding method thereof. Background technique [0002] The mold used for injection molding injection molded parts with internal threads has internal threads, and the cavity of the mold has a core that forms threads. The demoulding of the injection molded parts after injection molding of the existing mold is time-consuming and laborious, and the demoulding efficiency is low. It is extremely low, and automatic demoulding effect cannot be realized. These are also one of the factors affecting production efficiency, and the demoulding efficiency is also difficult to improve. For this problem, the inventor of the present case made improvements on the injection mold and this case came into being. Contents of the invention [0003] The purpose of the present invention is to provide a kind of injection mold with internal thread that can be a...
