Description

Technical Field

[0001] This application relates to the field of injection molds, and more particularly to a high-precision injection mold that facilitates demolding. Background Art

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

[0003] In each cycle of injection molding of injection molded parts, the plastic part must be removed from the mold cavity. However, due to the large number of undercut structures in the products produced by our company, it is extremely inconvenient to demold, resulting in inconvenient operation and reduced production efficiency. Therefore, a high-precision injection mold that facilitates demolding is provided. Summary of the Utility Model

[0004] A high-precision injection mold that facilitates demolding provided by this application adopts the following technical solutions:

[0005] A high-precision injection mold that facilitates demolding includes a male mold and a female mold. The female mold is provided with a mold core and a push plate. The push plate is provided with a groove and a plurality of chutes. A bottom plate is provided in the groove. The mold core extends into the groove. The bottom plate is sleeved on the mold core. Sliders are provided in the chutes. The male mold is provided with a plurality of inclined undercuts. The number of the plurality of inclined undercuts is the same as the number of the sliders. The sliders are provided with limit holes. The inclined undercuts are clamped in the limit holes.

[0006] A high-precision injection mold that facilitates demolding provided by an embodiment of the present disclosure can achieve the following technical effects:

[0007] When the mold is opened, the male mold moves away from the female mold. At this time, due to the inclination of the inclined undercut structure itself, the sliders can move along the chutes, that is, when the mold acts to open, the plurality of sliders are synchronously withdrawn, so as to demold, and the operation is simple. In actual operation, the push plate can be detached from the female mold, so that the push plate drives the bottom plate to move. At this time, the bottom plate drives the product to be detached from the mold core, and the operation is simple. By adopting the above structure, while ensuring the mold accuracy, the product can be quickly demolded when the mold is opened, the operation is simple, and it helps to improve the production efficiency.

[0008] The above general description and the following description are only exemplary and explanatory, and are not used to limit this application. Brief Description of the Drawings

[0012] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be 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 utility model and are not used to limit the present utility model.

[0013] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, in the description of the present utility model, the meaning of "a plurality of" is two or more unless otherwise specifically defined.

[0014] The following is further described in detail with reference to the attached Figure 1-2 This application is further described in detail.

[0015] A high-precision injection mold that is easy to demold includes a male mold 1 and a female mold 2. The female mold 2 is provided with a mold core 3 and a push plate 4. The push plate 4 is provided with a groove 5 and a plurality of chutes 6. A bottom plate 7 is provided in the groove 5. The mold core 3 extends into the groove 5. The bottom plate 7 is sleeved on the mold core 3. A slider 8 is provided in the chute 6. The male mold 1 is provided with a plurality of inclined undercuts 9. The number of the plurality of inclined undercuts 9 is the same as the number of the sliders 8. The slider 8 is provided with a limit hole 10. The inclined undercut 9 is clamped in the limit hole 10.

[0016] In this embodiment, the product has an annular structure. When producing the product, the annular structure is formed by the columnar mold core 3. A plurality of sliders 8 are spliced into the side wall structure of the product. The bottom plate 7 and the male mold 1 are used to form the upper and lower walls of the product. Among them, the structure of the side wall of the slider 8 determines the structure of the side wall of the product; the side wall structures of the bottom plate 7 and the male mold 1 determine the structures of the upper and lower walls of the product. After the male mold 1 and the female mold 2 are closed, the inclined undercut 9 is clamped into the limit hole 10 to limit the position of the slider 8 and prevent the slider 8 from sliding in the chute 6. The inclined undercut 9 and the limit hole 10 are provided with corresponding slopes.

[0017] When the mold is opened, the male mold 1 is away from the female mold 2. At this time, the inclination of the undercut 9 structure allows the slider 8 to move along the slide groove 6 due to its own inclination, that is, the mold movement opens the mold so that multiple sliders 8 are synchronously withdrawn, thereby demoulding, which is easy to operate. In actual operation, the push plate 4 can be separated from the female mold 2, so that the push plate 4 drives the bottom plate 7 to move. At this time, the bottom plate 7 drives the product to separate from the mold core 3, which is easy to operate. By adopting the above structure, while ensuring the mold accuracy, the product can be demoulded quickly when the mold is opened, which is easy to operate and helps to improve production efficiency.

[0018] In one embodiment, the mold is provided with two sets of the above-mentioned mold structures for forming the external structure of the product, which are composed of the mold core 3, the bottom plate 7, a plurality of sliders 8, a plurality of sloped undercuts 9, etc. The number of sliders 8 in one set of mold structures is 6, for example, and the six sliders 8 are arranged at equal intervals in the circumference of the circular product.

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