They use pressure, temperature, or mechanical action to shape metal materials into predetermined shapes and sizes, offering high precision, high efficiency, and long service life.

[0003] Existing metal molds typically have a removable and replaceable inner casting mold. However, in practice, removing the inner casting mold requires time to unscrew or bolts used to fix it. Similarly, reassembling the inner casting mold also requires time to fix it with screws or bolts. To reduce the difficulty of disassembling and assembling the inner casting mold, we propose a metal mold that is easy to disassemble and assemble. Utility Model Content

[0026] Please see Figure 1-7This utility model provides a technical solution: a metal mold that is easy to assemble and disassemble, including a supporting mold frame 1, an inner mold 3 installed inside the supporting mold frame 1, two sets of limiting components 4 and two sets of positioning components 5 fixedly installed on the side of the supporting mold frame 1, and four sets of auxiliary components 6 fixedly installed at the bottom of the supporting mold frame 1. The positioning component 5 includes a hollow block 17, which is fixedly installed on the supporting mold frame 1. A limiting post 18 is slidably installed inside the hollow block 17, and a limiting block 19 is fixedly installed on the limiting post 18. Two sets of mating slots are opened inside the supporting mold frame 1, and the limiting block 19 is slidably connected to the corresponding mating slot. A limiting spring 20 is fitted inside the portion of the limiting post 18 inside the hollow block 17, and a limiting hole 23 is opened on the limiting post 18. A limiting pin 24 is installed, which cooperates with the limiting hole 23. Two sets of positioning slots 11 are opened on the inner mold 3, and the positioning slots 11 cooperate with the corresponding limiting blocks 19. The auxiliary component 6 includes a hollow column 25, which is fixedly connected to the support mold frame 1. A round block 26 is slidably installed inside the hollow column 25. An auxiliary column 27 is fixedly installed above the round block 26 and is slidably connected to the support mold frame 1. A connecting column 28 is fixedly connected below the round block 26. An auxiliary spring 29 is fitted on the connecting column 28 and its bottom contacts the hollow column 25. A limiting plate 21 is fixedly installed on the limiting column 18, and a handle 22 is fixedly installed on the limiting plate 21. An anti-slip pad 30 is fixedly installed at the bottom of the hollow column 25.

[0027] In use, the inner mold 3 is installed into the support mold frame 1, and the inner mold 3 is pressed downwards with force. Then, the limiting pin 24 on the hollow block 17 is pulled upwards, allowing it to leave the limiting hole 23 of the limiting post 18, thereby releasing the restriction on the limiting post 18. Subsequently, under the action of the limiting spring 20 and the cooperation of the hollow block 17, the limiting block 19 on the limiting post 18 is pressed against the positioning groove 11 on the inner mold 3, thereby restricting the inner mold 3. Then, the downward pressure on the inner mold 3 can be removed. When the inner mold 3 needs to be removed, the limiting post 18 is pulled out by the handle 22, so that the limiting block 19 leaves the positioning slot 11. Then the limiting pin 24 is inserted into the limiting hole 23 to limit the limiting post 18. Subsequently, under the action of multiple sets of auxiliary springs 29, the inner mold 3 is pushed up, so as to facilitate the removal of the inner mold 3 from the support mold frame 1. The limiting circular plate 21 on the limiting post 18 plays the role of limiting the position of the limiting post 18, and the anti-slip pad 30 can improve the stability of the device.

[0028] An outer mold 2 is installed above the inner mold 3. Several protruding pillars 10 are fixedly installed above the inner mold 3. Several concave holes 9 are opened below the outer mold 2. The concave holes 9 cooperate with the corresponding protruding pillars 10. A feed hole 7 is opened in the middle of the outer mold 2. Several air vents 8 are opened on the outer mold 2. The limiting component 4 includes a connecting block 13. The connecting block 13 is fixedly connected to the support mold frame 1. A threaded pillar 12 is fixedly connected to the connecting block 13. A limiting plate 14 is fitted on the threaded pillar 12. A lower rotating block 15 is provided below the limiting plate 14. An upper rotating block 16 is provided on the limiting plate 14. Both the lower rotating block 15 and the upper rotating block 16 are threadedly connected to the threaded pillar 12.

[0029] In use, the outer mold 2 is installed on the inner mold 3 by cooperating with the concave hole 9 and the corresponding protrusion 10. Then, the position of the limiting plate 14 is adjusted by rotating the lower rotating block 15 so that it can rotate above the outer mold 2. Then, the limiting plate 14 is rotated above the outer mold 2. Next, the lower rotating block 15 and the upper rotating block 16 are adjusted so that the limiting plate 14 locks the outer mold 2. Then, the molten metal is introduced into the space between the outer mold and the inner mold 3 through the feed hole 7. The vent hole 8 is used to prevent air holes or defects from appearing on the surface of the workpiece.

[0030] Working principle: In use, the inner mold 3 is installed into the support mold frame 1, and the inner mold 3 is pressed downwards with force. Then, the limiting pin 24 on the hollow block 17 is pulled upwards, allowing it to move away from the limiting hole 23 of the limiting post 18, thereby releasing the restriction on the limiting post 18. Subsequently, under the action of the limiting spring 20 and the cooperation of the hollow block 17, the limiting block 19 on the limiting post 18 is pressed against the positioning groove 11 on the inner mold 3, thereby restricting the inner mold 3. Then, the downward pressure on the inner mold 3 can be removed. Pressure; When it is necessary to remove the inner mold 3, the limit post 18 is pulled out by the handle 22, so that the limit block 19 leaves the positioning slot 11. Then the limit pin 24 is inserted into the limit hole 23 to limit the limit post 18. Subsequently, under the action of multiple sets of auxiliary springs 29, the inner mold 3 is pushed up, so as to facilitate the removal of the inner mold 3 from the support mold frame 1. The limit circular plate 21 on the limit post 18 plays the role of limiting the position of the limit post 18, and the anti-slip pad 30 can improve the stability of the device.

[0031] The outer mold 2 is installed onto the inner mold 3 by the cooperation of the concave hole 9 and the corresponding protrusion 10. Then, the position of the limiting plate 14 is adjusted by rotating the lower rotating block 15 so that it can rotate above the outer mold 2. The limiting plate 14 is then rotated above the outer mold 2. Next, the lower rotating block 15 and the upper rotating block 16 are adjusted so that the limiting plate 14 locks the outer mold 2. Then, the molten metal is fed into the space between the outer mold and the inner mold 3 through the feed hole 7. The vent hole 8 is used to prevent air holes or defects from appearing on the surface of the workpiece. This design is simple and reduces the difficulty of disassembling and assembling the inner mold 3.
