[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Example 1

[0020] Please see Figures 1-4 This utility model provides a technical solution: an injection mold, including an operating table 1, a cooling box 2 at the upper end of the operating table 1, a lower template 3 inside the cooling box 2, connecting plates 4 fixedly connected to both sides of the lower template 3, a connecting ring 5 fixedly connected to the lower end of the connecting plate 4, a connecting ring 6 movably connected inside the connecting ring 5, a short rod 7 fixedly connected to the lower end of the connecting ring 6, a threaded sleeve 8 fixedly connected to the other end of the short rod 7, a threaded column 9 fixedly connected to the upper end of the operating table 1 near the cooling box 2, and the threaded sleeve 8 movably connected to the connecting plate 4 through a retaining ring and retaining ring.

[0021] Specifically, rotating the threaded sleeve 8 causes it to slide along the outside of the threaded column 9 under the action of its internal threads and the external threads of the threaded column 9, thus separating the threaded sleeve 8 and the threaded column 9. Pulling the lower template 3 upward causes it to slide out along the inside of the cooling box 2, thus disassembling the lower template 3. Similarly, during installation, the lower template 3 is slid along the inner wall of the cooling box 2, and the threaded sleeve 8 is rotated in the opposite direction, allowing the threaded column 9 to enter the threaded sleeve 8, thus installing the lower template 3. The connecting ring 5 and the connecting ring 6 prevent the threaded sleeve 8 from rotating and shifting, which would affect the installation effect. The lower template 3 can be disassembled by the connecting ring 6, the connecting ring 5, the threaded sleeve 8, and the threaded column 9, allowing for replacement after long-term use. Compared with the traditional fixing method, this fixing method can reduce the time spent on replacement and improve work efficiency.

[0022] Example 2

[0023] Please see Figures 1-4This utility model provides a technical solution: an injection mold, wherein a support rod 10 is fixedly connected to the upper edge of the operating table 1, an electric push rod 11 is provided on one side of the support rod 10, an upper template 12 is fixedly connected to the other end of the electric push rod 11, and arc plates 14 are fixedly connected to both sides of the upper template 12. A water inlet pipe 13 is provided on one side of the cooling box 2. A buffer groove 15 is provided inside the operating table 1, a buffer block 16 is provided inside the buffer groove 15, a sliding groove 17 is provided inside the buffer block 16, a slider 18 is slidably connected inside the sliding groove 17, a retaining plate 19 is fixedly connected to the left side of the slider 18, a telescopic rod 20 is provided at the lower end of the retaining plate 19, a spring 21 is sleeved on the outside of the telescopic rod 20, and a connecting block 22 is fixedly connected to the upper end of the retaining plate 19. The slider 18 slides in the sliding groove 17 through the retaining plate 19 in cooperation with the telescopic rod 20 and the spring 21. There are multiple sets of retaining plates 19, and they are symmetrically arranged about the center line of the operating table 1.

[0024] Specifically, when the electric push rod 11 is activated, the upper template 12 moves to the lower template 3 under the action of the electric push rod 11. The arc plate 14 enters the interior of the buffer groove 15 and squeezes the connecting block 22. The connecting block 22 causes the clamping plate 19 to compress the telescopic rod 20 and the spring 21. The spring 21 absorbs the pressure of the arc plate 14 and converts it into the potential energy of the spring 21. The spring 21 rebounds and causes the telescopic rod 20 to push the clamping plate 19 and the connecting block 22 upward. Under the action of the arc plate 14, the upper template 12 moves upward, realizing the separation of the upper template 12 and the lower template 3. Through the telescopic rod 20, the spring 21, the clamping plate 19, the connecting block 22 and the arc plate 14, the upper template 12 and the lower template 3 can be separated quickly, thereby achieving the purpose of rapid demolding.

[0025] Working Principle: When using this injection mold, firstly, the water inlet pipe 13 is connected to an external water supply pipe, allowing water to enter the cooling tank 2 and circulate through another set of water inlet pipes 13, thereby accelerating the rapid molding of the mold. Finally, the molten material is poured into the lower mold plate 3 and the electric push rod 11 is activated. Under the action of the electric push rod 11, the upper mold plate 12 moves to the lower mold plate 3, and the arc plate 14 enters the interior of the buffer groove 15 and squeezes the connecting block 22. The connecting block 22 causes the clamping plate 19 to compress the telescopic rod 20 and the spring 21. The spring 21 absorbs the pressure of the arc plate 14 and converts it into the spring 21's potential energy. The spring 21 rebounds, causing the telescopic rod 20 to push the clamping plate 19 and the connecting block 22 upward. Under the action of the arc plate 14, the upper mold plate 12 moves upward, realizing the separation of the upper mold plate 12 and the lower mold plate 3. Through the telescopic rod 20, the spring 21, the clamping plate 19, the connecting block 22, and the arc plate 14, the upper mold plate 12 and the lower mold plate 3 can be separated quickly. This achieves rapid demolding. When the lower mold plate 3 needs to be replaced after long-term use, the threaded sleeve 8 is rotated. Under the action of its internal thread and the external thread of the threaded column 9, the threaded sleeve 8 slides along the outside of the threaded column 9, realizing the separation of the threaded sleeve 8 and the threaded column 9. The lower mold plate 3 is pulled upward, and the lower mold plate 3 slides out along the inside of the cooling box 2, realizing the disassembly of the lower mold plate 3. Similarly, during installation, the lower mold plate 3 is slid along the inner wall of the cooling box 2, and the threaded sleeve 8 is rotated in the opposite direction. The threaded column 9 enters the threaded sleeve 8, realizing the installation of the lower mold plate 3. Under the action of the connecting ring 5 and the connecting ring 6, the threaded sleeve 8 can be prevented from rotating and shifting, which would affect the installation effect. The lower mold plate 3 can be disassembled by the connecting ring 6, the connecting ring 5, the threaded sleeve 8 and the threaded column 9, so that it can be replaced after long-term use. Compared with the traditional fixing method, this fixing method can reduce the time spent on replacement and improve the efficiency of work.
