Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing, and more specifically, to an injection mold. Background Art

[0002] When injection molding a relatively small injection molded part, the method of "one out of four", "one out of eight" or "one out of sixteen" is often used. However, the demoulded product will be connected with the waste material. If the waste material is removed manually, it will be difficult to cut down due to the small product and small adjacent gap, and the overall effect is not good. Based on this, the utility model proposes an injection mold. Utility Model Content

[0006] The utility model is further configured as follows: the core column is provided with a limiting groove which is opened on the mold body and extends circumferentially, the limiting groove is slidably connected with a limiting block, and the limiting block is arranged on the core column.

[0007] The utility model is further configured as follows: the extension angle of the limiting groove is 15° to 45°.

[0008] The utility model is further configured as follows: the extension angle of the limit groove is 25°.

[0009] In summary, the utility model has the following beneficial effects: the injection mold involved in the utility model drives the core column to rotate appropriately before the product is demolded, so that the waste solidified in the injection branch channel is cut off, which is convenient for cleaning the waste on the demolded product. The overall function is perfect and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0013] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See also Figure 1 and Figure 2 As shown, an injection mold involved in this embodiment includes a mold body 1, on which an injection main channel 2 is opened, and a plurality of molding cavities 3 opened on the mold body are arranged around the periphery of the injection main channel 2, and an injection branch channel 4 also opened on the mold body 1 is connected between each of the molding cavities 3 and the injection main channel 2, and a core column 5 surrounded by all the molding cavities in the center is rotatably connected to the mold body 1, and the injection main channel 2 is opened on the core column 5, and the injection branch channel 4 consists of a movable channel 41 opened on the core column and a fixed channel 42 opened on the mold body, and a power assembly for controlling the rotation is provided on the core column 5, and the power assembly is arranged on the mold body 1.

[0016] Furthermore, the power assembly includes a driving plate 6 arranged at the rear end of the core column 5, and a driving arm 7 extending radially is provided on the driving plate 6. The power assembly also includes a push rod cylinder 8 with one end hinged to the driving arm and the other end hinged to the mold body.

[0017] In this embodiment, when the product is completed by injection molding and is ready for demolding, the push rod cylinder 8 is extended and retracted to control the swing of the drive arm, so that the drive plate 6 and the core column 5 rotate, causing the movable channel 41 and the fixed channel 42 on the same injection branch channel 4 to be misaligned, cutting off the waste solidified in the injection branch channel 4, making it easier to clean the waste on the product after demolding.
