[0030] The present invention will be described in further detail below with reference to the accompanying drawings. Like components are denoted by like reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0031] Example 1

[0032] This embodiment discloses a bottom shell processing mold, referring to Figures 1 to 3 The upper mold 1 and the lower mold 2 are composed of two major parts: an upper mold 1 and a lower mold 2. An injection port 10 is designed at the top of the upper mold 1, which is located in the center of the upper mold base 3. This design allows the injection head of the injection molding machine to be easily docked, improving injection efficiency. The upper mold 1 consists of an upper mold base 3, an upper mold plate 4, and multiple upper mold inserts 5 of various shapes, while the lower mold 2 correspondingly includes a lower mold base 6, a lower mold plate 7, and multiple lower mold inserts 8. Among them, the upper mold inserts 5 and the lower mold inserts 8 are carefully provided with a wear-resistant layer 11 on the surfaces in contact with each other. The wear-resistant layer 11 is made of a cemented carbide layer, and a ceramic coating can also be used. The ceramic coating also has excellent wear resistance and corrosion resistance, and may show better performance in certain application scenarios. This ensures that excellent wear resistance and corrosion resistance can be maintained during long-term use.

[0033] A guide assembly 9 is located between the upper die base 3 and the lower die base 6. This ingenious design comprises a guide post 91 and a guide hole 92. The guide post 91 is mounted on the upper die base 3, while the guide hole 92 is located in the lower die base 6. To ensure precise positioning during mold closing, a guide sleeve 93 is positioned within the guide hole 92, allowing the guide post 91 and the guide sleeve 93 to fit perfectly together for precise guidance. Furthermore, the upper die base 3 is equipped with multiple locating pins 15, which mate with locating holes 16 in the lower die base 6, further enhancing the mold's positioning accuracy.

[0034] In order to further improve production efficiency and product quality, a cooling system 17 is provided in the mold. The cooling system 17 includes cooling channels provided in the upper mold base 3 and the lower mold base 6. These channels are connected to external cooling equipment through inlets and outlets. During the bottom shell molding process, the coolant enters the cooling channel through the inlet, circulates to take away the heat generated by the mold, and finally flows out through the outlet.

[0035] Finally, in order to facilitate the transportation and installation of the mold, lifting holes 18 are set on the upper template 4 and the lower template 7.

[0036] The working principle of Example 1 is as follows: During the bottom shell processing, the upper mold 1 and the lower mold 2 are precisely clamped together by the guide assembly 9 to form a mold cavity. The injection molding machine injects plastic material into the mold cavity through the injection port 10. After cooling by the cooling system 17, the bottom shell is formed. The circulating cooling effect of the cooling system 17 effectively reduces the temperature generated by the mold during the processing, thereby shortening the cooling time of the bottom shell and improving production efficiency. At the same time, the provision of the wear-resistant layer 11 extends the service life of the mold and reduces maintenance costs.

[0037] Example 2

[0038] Reference Figure 2 and Figure 3 The difference in this embodiment lies in the design of the upper mold insert 5 and the lower mold insert 8. In this embodiment, the inserts adopt a modular design and are detachably connected to the upper mold base 3 and the lower mold base 6. To achieve this design, the upper mold base 3 and the lower mold base 6 are each machined with mounting grooves 12, which are used to mount the upper mold insert 5 and the lower mold insert 8. Furthermore, the mounting grooves 12 are machined with multiple mounting holes 13, and bolts 14 are also provided on the upper mold insert 5 and the lower mold insert 8. These bolts 14 ensure that the upper mold insert 5 and the lower mold insert 8 are securely and detachably connected within the mounting grooves 12.

[0039] 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.
