Description

Technical Field

[0001] The utility model relates to the technical field of injection mold cores, in particular to an anti-stripping injection mold core mechanism. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and complex-shaped products and other molding and processing fields.

[0003] At present, in the injection molding manufacturing of the cooling fan housing, the cooling fan housing includes hardware and plastic parts. During the injection molding process, it is necessary to open the mold first, place the hardware in the mold core, and then close the mold. However, during the mold closing process, due to the vibration during mold closing and the influence of the moving speed, the hardware is easy to separate from the mold core or fall off, which in turn affects the subsequent plastic injection molding process, reduces the injection molding quality of the product, and increases the defective rate. For this reason, we propose an anti-demolding injection mold core mechanism. Utility Model Content

[0007] Furthermore, the positioning column is in a rectangular shape, which is compatible with the rectangular hole of the hardware product.

[0008] Furthermore, the number of the positioning posts is three and they are arranged in a circle.

[0009] Furthermore, the baffle is a rectangular structure.

[0010] Furthermore, an insert is installed at one end of the female mold core away from the male mold core.

[0011] The beneficial effects of the utility model are:

[0012] Compared with the prior art, the utility model is provided with a positioning column and a baffle, and the space for connecting the rectangular positioning column with the rectangular hole of the hardware is larger, which can effectively clamp the hardware in the forming hole. In addition, a rectangular baffle is also provided to form abutment with the hardware and further clamp the hardware, so that the installation of the hardware at the forming hole is more secure. During the mold closing process, it can effectively prevent the hardware from falling off or detaching, achieve the effect of anti-demolding, and then ensure the quality of plastic injection molding after mold closing, and has strong practicality.

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0018] like Figure 1-3 As shown,

[0019] An anti-demolding injection mold core mechanism comprises a mold core body 1, wherein the mold core body 1 is composed of a male mold core 2 and a female mold core 3; the male mold core 2 and the female mold core 3 are fixedly connected; the female mold core 3 is respectively provided with a positioning column 4 and a baffle 5, and the male mold core 2 is provided with a molding hole 6, and the other ends of the positioning column 4 and the baffle 5 extend to the molding hole 6, and the positioning column 4 is used to be inserted into the rectangular hole of the hardware product, and the baffle 5 is used to abut against the side of the hardware product; in this embodiment, the hardware is mainly clamped and limited by the positioning column 4 and the baffle 5, so that when the mold is moved during mold closing, it is not easy to be demolded under the influence of vibration or speed, and the injection molding quality is effectively ensured; in addition, four molding holes 6 are provided in the present application, and four hardware parts can be injection molded at the same time, and the production efficiency is relatively high;

[0020] It should be pointed out that hardware of different types (or specifications) can be replaced with corresponding positioning posts 4 and baffles 5, as long as the positioning posts 4 are compatible with the rectangular holes of the hardware.

[0021] As a preferred embodiment, the positioning column 4 is rectangular in shape, which is adapted to the rectangular hole of the hardware product. The purpose of this design is that after the rectangular positioning column 4 is connected to the hardware, the clamping position space is larger, thereby enhancing the firmness of the hardware after connection and preventing demolding.

[0022] As a preferred embodiment, the number of the positioning posts 4 is three and they are arranged in a circle. The structural arrangement of the positioning posts 4 can form a snap connection with the hardware in a circumferential direction, which can further improve the firmness of the hardware after installation.

[0023] As a preferred embodiment, the baffle 5 is a rectangular structure. It can be understood that one side of the hardware is a planar structure, and after the baffle 5 is set to a rectangular structure, it can better fit the hardware, not only can it further clamp and fix the hardware, but also can block the hardware (during the mold closing process, the mold moves in the horizontal direction), and it is not easy to fall off.

[0024] As a preferred embodiment; the end of the female mold core 3 away from the male mold core 2 is connected with an insert 7, and the insert 7 can improve the hardness and durability of the male mold core 2, the female mold core 3 or the entire mold, prevent the mold from wear and deformation during use, and thus extend the service life of the mold.

[0025] The anti-stripping principle of the utility model is: after the mold is opened, the hardware is installed in the forming hole 6, the positioning column 4 will be stuck in the rectangular hole of the hardware, and the baffle 5 just abuts on the side of the hardware, which has the function of limiting and resisting the hardware, so that the hardware is not easy to fall off;

[0026] It is worth mentioning that the main problems in the prior art are: during the mold closing process, due to the vibration during mold closing and the influence of the moving speed, the hardware is easily separated from the mold core or the hardware falls off, which in turn affects the subsequent plastic injection molding process, reduces the injection molding quality of the product, and increases the defective rate;

[0027] Therefore, after the improvement of the present application, by providing the positioning column 4 and the baffle 5, the space for connecting the rectangular positioning column 4 with the rectangular hole of the hardware is larger, which can effectively clamp the hardware in the forming hole 6. In addition, a rectangular baffle 5 is also provided to form abutment with the hardware and further clamp the hardware, so that the installation of the hardware at the forming hole 6 is more secure. During the mold closing process, it can effectively prevent the hardware from falling off or detaching, thereby achieving an anti-demolding effect, thereby ensuring the quality of plastic injection molding after mold closing.

[0028] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
