Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0026] Combine Figure 1 The utility model is an injection mold for producing a computer shell, comprising a fixing mechanism 1, an injection driving mechanism 2 is fixedly provided on the upper end of the fixing mechanism 1, an injection mold plate 3 is movably engaged in the injection driving mechanism 2, and the injection mold plate 3 is provided with multiple groups, the injection driving mechanism 2 comprises a first fixing frame 22 and a second fixing frame 23 fixedly provided on the upper end of the fixing mechanism 1, a driving cylinder 21 is connected to one side of the first fixing frame 22, and a push plate 25 is provided at the output end of the driving cylinder 21, and the first fixing frame 22 is provided with a push plate 25. The frame 22 and the second fixed frame 23 are connected with four sets of rectangular guide rails 24. The injection mold plate 3 includes a template block 31. Vertical sliding grooves 34 are provided on both sides of the template block 31 corresponding to the rectangular guide rails 24. Engaging grooves 311 are provided on both sides of the template block 31. Engaging components 32 are inserted into the engaging grooves 311. The engaging components 32 include an insert block 324 that is slidably engaged in the engaging groove 311. A spring 322 is connected to one end of the insert block 324. A triangular opening 3241 is provided on one side of the insert block 324.

[0027] Specifically, the first fixing frame 22 and the second fixing frame 23 are fixed to each other with the fixing mechanism 1, and the driving cylinder 21 can drive the push plate 25 to move along the rectangular guide rail 24 to extrude multiple groups of injection mold plates 3. The raw material is driven to be injected into the injection mold plate 3 through the injection assembly 13 on one side of the second fixing frame 23. The vertical slide groove 34 is equal to the width of the rectangular guide rail 24, so that the sizes of the template block 31 fit each other when inserted into the rectangular guide rail 24 from top to bottom. The setting of the triangular opening 3241 enables the rectangular guide rail 24 to squeeze the insert block 324 toward both ends when the template block 31 is pressed down to prevent the engagement from being blocked. The spring 322 provides elastic force for the insert block 324. At the same time, the engagement height of the upper end of the insert block 324 is aligned with the lowest height of the two sets of rectangular guide rails 24 at the lower end, so that the injection mold plate 3 can be fixed within the range surrounded by the four sets of rectangular guide rails 24. The push plate 25 is horizontally shifted left and right, which can push the multiple sets of injection mold plates 3 sleeved on the rectangular guide rails 24 to fit together to complete the injection molding of the computer shell. This structural setting makes the fixing mechanism 1 and the injection driving mechanism 2 universal, and the injection mold plate 3 can be disassembled and replaced vertically to adapt to the design of computer shells of different sizes, realizing multiple uses of one device.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Combine Figure 2-Figure 4 The fixing mechanism 1 includes a fixing frame 11, a receiving box 12 slidably arranged inside the fixing frame 11, and an injection assembly 13 fixedly arranged on one side of the upper end of the fixing frame 11. The receiving box 12 and the injection mold plate 3 are arranged correspondingly up and down. The output end of the injection assembly 13 is inserted into the second fixing frame 23. The fixing frame 11 plays a fixing role. The receiving box 12 is used to receive the injection molded parts, and the injection assembly 13 inputs raw materials into the second fixing frame 23.

[0031] The material injection assembly 13 includes a material box 132 fixedly arranged at the upper end of the fixed frame 11, a hopper 131 is arranged at the upper end of the material box 132, the lower end of the hopper 131 is connected to a built-in spiral tube 134, one end of the built-in spiral tube 134 is connected to a spiral conveying motor 133, the hopper 131 feeds material into the interior of the built-in spiral tube 134, the spiral conveying motor 133 drives the spiral rotation inside the built-in spiral tube 134 to transport raw materials to the side of the second fixed frame 23, and the second fixed frame 23 and the output end of the built-in spiral tube 134 are fixedly arranged.

[0032] The second fixing frame 23 includes a positioning plate 231 connected to the built-in spiral tube 134, and an injection molding side plate 232 is connected to one side of the positioning plate 231. The positioning plate 231 fits with the side of the injection mold plate 3. The positioning plate 231 plays a fixing role, and the mutual fit between the injection molding side plate 232 and the injection mold plate 3 increases the fit of the injection molding.

[0033] Example 2:

[0034] Combine Figure 4-Figure 6 The template block 31 is aligned with the output end of the built-in spiral tube 134 and is provided with an injection port 33. The injection ports 33 on the multiple groups of injection mold plates 3 are arranged in a collinear manner for feeding.

[0035] The injection port 33 is connected to the surrounding area with a semicircular injection groove 312, and the outer end of the semicircular injection groove 312 is connected to the computer shell groove 313. The semicircular injection groove 312 and the computer shell groove 313 are connected to each other. The injection mold plate 3 placed in the middle is provided with a semicircular injection groove 312 and a computer shell groove 313 on both sides.
