Description

Technical Field

[0001] The present invention relates to the field of injection molds, and in particular to a high-precision injection mold with automatic demoulding. Background Art

[0002] Injection molded parts refer to various injection molded products produced by injection molding machines, including various packaging, parts, etc. They are mainly made of materials such as polyethylene or polypropylene and added with various organic solvents. Injection molded parts need to be cooled before they can be used.

[0003] During each injection molding cycle, the molded part must be ejected from the mold cavity. However, due to the high number of undercuts in our products, demolding is extremely difficult, resulting in operational difficulties and reduced production efficiency. Therefore, we need to provide a high-precision injection mold that facilitates demolding. Utility Model Content

[0004] The present application provides a high-precision injection mold with automatic demoulding, which adopts the following technical solutions:

[0005] A high-precision injection mold with automatic demolding includes a male mold and a female mold, the female mold is provided with multiple first slide grooves and multiple second slide grooves, the first slide groove is provided with a first slider, the first slider is used to form the circumferential structure of the product, the male mold is provided with multiple slope undercuts and multiple second sliders, the number of the slope undercuts is the same as the number of sliders, the number of the second sliders is the same as the second slide grooves, the first slider is provided with a limiting hole, the slope undercut is clamped in the limiting hole, and the second slider is provided in the second slide groove.

[0006] The embodiment of the present disclosure provides a high-precision injection mold with automatic demoulding, which can achieve the following technical effects:

[0007] The use of sliders can solve complex mold structures and mold opening actions. At the same time, the 6 sliders can be synchronized to exit when the mold is opened, solving the problem of product demoulding. It is easy to operate and helps to improve production efficiency.

[0008] The above general description and the following description are exemplary and explanatory only and are not intended to limit the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0013] In the description of the present invention, it should be understood that the terms "length," "width," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," and the like, indicating positions or location relationships, are based on the positions or location relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, in the description of the present invention, "plurality" means two or more, unless otherwise expressly and specifically defined.

[0014] The following is combined with Figure 1-2 This application is described in further detail.

[0015] A high-precision injection mold with automatic demoulding includes a male mold 1 and a female mold 2. The female mold 2 is provided with multiple first slide grooves 3 and multiple second slide grooves 4. A first slider 5 is provided in the first slide groove 3. The first slider 5 is used to form the side wall structure of the product. The male mold 1 is provided with multiple slope undercuts 6 and multiple second sliders 7. The number of slope undercuts 6 is the same as the number of sliders, and the number of second sliders 7 is the same as the number of second slide grooves 4. The first slider 5 is provided with a limiting hole 8. The slope undercut 6 is clamped in the limiting hole 8. The second slider 7 is provided in the second slide groove 4.

[0016] In this embodiment, the product shape is a square. The number of first sliders 5 and the number of sloped undercuts 6 are both four. The four first sliders 5 are evenly divided into two groups, i.e., two first sliders 5 are used to construct the structure of the opposite side walls of a product. This mold can produce two products simultaneously.

[0017] Taking two second sliding blocks 7 as an example, the two second sliding blocks 7 are arranged on the side wall of the male mold 1 facing the female mold 2 and are arranged opposite to each other along the length direction of the male mold 1 .

[0018] During mold opening, the mold-opening force pushes out the second slider 7 on the side wall of the male mold 1, which then releases the oblique undercut 6 structure of the male mold 1. The sliders can solve complex mold structures and mold opening movements. Simultaneously, the six sliders move out during mold opening, solving product demoulding problems. This is easy to operate and helps improve production efficiency.

[0019] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
