Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0027] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0028] In one embodiment of the present invention, Figures 1 to 4 As shown, a mouse button automatic positioning and demolding mold is provided, comprising an upper mold base 10 and a lower mold base 20. The upper mold base 10 is provided with an upper mold core 11. The lower mold base 20 is provided below the upper mold base 10 and connected to the upper mold base 10. The lower mold base 20 is provided with a lower mold core 21 corresponding to the upper mold core 11.

[0029] The upper die base 10 is equipped with four sets of guide posts 12. These four sets of guide posts 12 are arranged circumferentially around the upper die base 10. They serve to guide the upper die base 10 and the lower die base 20. The upper die base 10 is also equipped with positioning blocks 13 and four sets of positioning posts 14. The positioning posts 14 are located inside the guide posts 12, while the positioning blocks 13 are located on one side of the upper die base 10.

[0030] The lower die base 20 is provided with four sets of positioning holes 22 corresponding to the positioning posts 14. A first positioning seat 23 corresponding to the positioning block 13 is provided on one side of the lower die base 20. The positioning posts 14 and the positioning holes 22, and the positioning block 13 and the first positioning seat 23 are all used for the mold closing and positioning of the upper die base 10 and the lower die base 20.

[0031] When the upper mold base 10 and the lower mold base 20 are closed, the guide column 12 plays a guiding role to prevent the upper mold base 10 and the lower mold base 20 from having position deviation. At the same time, the positioning column 14 and the positioning block 13, and the positioning block 13 and the first positioning seat 23 cooperate to further perform a positioning function on the upper mold base 10 and the lower mold base 20 when the mold is closed, thereby preventing a small position deviation between the upper mold base 10 and the lower mold base 20, thereby realizing the positioning of the upper mold base 10 and the lower mold base 20, improving the production quality of the product, and improving production efficiency.

[0032] Furthermore, a second positioning seat 15 is provided on both sides of the upper mold base 10. Positioning pins 24 corresponding to the second positioning seat 15 are provided on both sides of the lower mold base 20, and the positioning pins 24 can enter or exit the second positioning seat 15. The second positioning seat 15 and the positioning pins 24 are used for the mold closing positioning of the upper mold base 10 and the lower mold base 20. When closing the mold, the positioning pins 24 and the second positioning seat 15 are mutually engaged, thereby positioning the upper mold base 10 and the lower mold base 20, further improving the position accuracy of the mold closing. At the same time, when producing different types of mouse buttons, the corresponding positioning pins 24 and second positioning seat 15 can be replaced, so that the mold can adapt to different types of products and improve its own practicality.

[0033] Furthermore, the lower die base 20 is provided with four sets of guide sleeves 25 corresponding to the guide posts 12. The guide posts 12 can enter or exit the guide sleeves 25. The cooperation between the guide sleeves 25 and the guide posts 12 guides the upper die base 10 and the lower die base 20 when closing or opening the mold, preventing large position deviation between the upper die base 10 and the lower die base 20, thereby improving production quality.

[0034] Furthermore, the upper die base 10 includes a top plate 101 and an upper die plate 102. The upper die plate 102 is located below the top plate 101, and the upper die core 11 is located in the center of the upper die plate 102. The lower die base 20 includes a bottom plate 201, a lower die plate 202, and two sets of support blocks 204. The two sets of support blocks 204 are symmetrically arranged on the bottom plate 201, the lower die plate 202 is arranged on the support blocks 204, and the lower die core 21 is located in the center of the lower die plate 202. The lower die base 20 also includes an ejector plate 203, which is arranged between the lower die plate 202 and the bottom plate 201 and within the two sets of support blocks 204. The ejector plate 203 is provided with several sets of springs 26, which are arranged between the lower die plate 202 and the ejector plate 203. The ejector plate 203 is provided with several sets of ejector pins 27. One end of the ejector pin 27 passes through the spring 26 and extends through the lower mold plate 202 to the lower mold core 21. When the mold is opened, the ejector plate 203 is pushed upward by the external push rod, so that the ejector pin 27 moves and the molded product is lifted from the lower mold core 21, making it easier for the staff to take the material.

[0035] Furthermore, the upper die base 10 is provided with a first insert 16 and a second insert 17. Both inserts 16 and 17 are located within the upper die base 10 and are circumferentially distributed around the upper die core 11. Wear-resistant blocks 18 are provided on either side of the first insert 16. These blocks are connected to the upper die base 10 and serve to protect the upper die base 10 from damage. The wear-resistant blocks 18 reduce wear on the upper die base 10 at the first insert 16 during mold closing, thereby increasing the service life of the first insert 16.

[0036] Furthermore, a first water inlet 19a and a first water outlet 19b are provided on one side of the upper mold base 10, and the first water inlet 19a is provided on one side of the first water outlet 19b. A second water inlet 28a and a second water outlet 28b are provided on one side of the lower mold base, and the second water inlet 28a is provided on one side of the second water outlet 28b. The first water inlet 19a and the second water inlet 28a are respectively connected to an external water inlet pipe, and the first water outlet 19b and the second water outlet 28b are respectively connected to an external water outlet pipe. When the mold is closed, the coolant flows from the first water inlet 19a and the second water inlet 28a into the upper mold base 10 and the lower mold base 20, respectively, to cool the upper mold core 11 and the lower mold core 21, so that the molded product can be cooled quickly, preventing product deformation and improving product production quality.

[0037] By setting the guide column 12, the positioning column 14, the positioning hole 22, the positioning block 13 and the first positioning seat 23, when the upper mold base 10 and the lower mold base 20 are closed, the guide column 12 plays a guiding role to prevent the upper mold base 10 and the lower mold base 20 from having position deviation. At the same time, through the cooperation of the positioning column 14 and the positioning block 13, and the positioning block 13 and the first positioning seat 23, the upper mold base 10 and the lower mold base 20 are further positioned when the mold is closed to prevent a small position deviation between the upper mold base 10 and the lower mold base 20, thereby realizing the positioning of the upper mold base 10 and the lower mold base 20, improving the production quality of the product, and improving the production efficiency.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
