Description

Technical Field

[0001] This utility model relates to the field of metal casting mold technology, and in particular to a metal casting mold with high-efficiency cooling. Background Technology

[0002] High-efficiency cooling metal casting molds are casting tooling designed around the core requirement of "rapid and uniform heat dissipation". Essentially, they are special molds that achieve rapid and uniform solidification of molten metal after it is injected into the mold cavity by optimizing the mechanical structure and heat transfer path.

[0003] The traditional basic cooling methods for metal casting molds are mainly water cooling, air cooling, and oil cooling. Cooling water, air, or heat transfer oil are introduced through simple straight holes in the mold to achieve heat dissipation.

[0004] Current cooling technologies still have limitations: traditional water cooling absorbs heat only through contact between the coolant and the mold cavity, resulting in low cooling efficiency and leading to problems such as long solidification cycles and porous internal structures in castings; the integrated design of the cooling channels and cavity structure of the mold requires replacing the entire mold when processing metal castings of different specifications and shapes. Therefore, it is necessary to develop a highly efficient cooling metal casting mold to address the shortcomings of existing technologies. Utility Model Content

[0020] Reference Figure 1-3This utility model provides an embodiment of a high-efficiency cooling metal casting mold, comprising a base 1, a lower mold 2 fixedly connected to the top of the base 1, an upper mold 3 slidably connected to the top of the lower mold 2, a pouring hole on the top of the upper mold 3 for injecting high-temperature molten metal into the lower mold cavity 4, a lower mold cavity 4 slidably connected to the inner wall of the lower mold 2, a high-temperature resistant sealing ring fixedly connected to the middle of the outer wall of the lower mold cavity 4 to prevent coolant leakage, uniformly distributed first heat sinks 5 fixedly connected to the bottom of the four sides of the lower mold cavity 4, and uniformly distributed second heat sinks 6 fixedly connected to the bottom of the lower mold cavity 4. The heat sinks can increase the contact area between the lower mold cavity 4 and the coolant. Uniformly distributed turbulence holes 7 are opened on one side of the first heat sink 5 and the second heat sink 6, with a diameter of 2-5mm, and are distributed in a matrix on the heat sink. When the coolant passes through the turbulence holes 7, the coolant is forced to turbulent, further improving the heat exchange effect. Limiting grooves 8 are opened on both sides of the lower mold cavity 4, and a connecting pipe 9 is passed through and fixedly connected to one side of the lower mold 2. A return pipe 10 is connected and fixedly connected to a water tank 11 at one end. A valve 12 is installed on the outer ring of the return pipe 10.

One end of the transmission pipe is connected and fixedly connected to the water tank 11. Coolant is drawn from the water tank 11 through the transmission pipe. After heat is collected, the coolant returns to the water tank 11 through the return pipe. When the circulation pump 33 is started, the valve 12 needs to be closed to fill the lower mold 2 with coolant. When the circulation pump 33 is stopped, the coolant inside the lower mold 2 will return to the water tank 11 through the return pipe 10 under the influence of gravity. The coolant does not remain inside the lower mold 2, which affects the replacement of the lower mold cavity 4. The lower mold 2 is fixedly connected to both ends of the fixed frame 14. The fixed frame 14 is equipped with quick-release components on both sides of one end, and the fixed plate 13 is equipped with a transmission component on the other side of the top.

The other end of the limiting post 15 is fixedly connected to a sliding rod 17, one end of which is slidably connected to the fixing frame 14. A spring 16 is sleeved on the outer ring of the sliding rod 17. When the sliding rod 17 is pulled outward, so that the limiting post 15 slides completely out of the limiting groove 8, the limiting on the lower mold cavity 4 is released. The transmission assembly includes a support frame 19, the bottom of which is connected to the fixing plate 1. 3. Fixed connection: A first frame 22 is fixedly connected to the top center of the fixed plate 13. A first fan blade rod 21 is rotatably connected through one side of the first frame 22. One end of the first fan blade rod 21 is fixedly connected to the output end of the servo motor 20. A first bevel gear 23 is rotatably connected through the outer ring of the first fan blade rod 21. When the servo motor 20 starts, its output end drives the first fan blade rod 21 and the first bevel gear 23 to rotate synchronously. The rotation of the first fan blade rod 21 blows cold air toward the water tank 11, cooling the coolant in the water tank 11 and preventing the water that has absorbed heat from flowing back into the water tank 11, thus keeping the coolant circulating smoothly. As the body temperature rises, the cooling effect is affected. A fixing block 32 is fixedly connected to one side of the inner wall of the support frame 19. A connecting column 25 is rotatably connected through the top of the fixing block 32. A second bevel gear 24 is fixedly connected to both ends of the connecting column 25. The bottom second bevel gear 24 meshes with a first bevel gear 23. The rotation of the first bevel gear 23 drives the connecting column 25 and the second bevel gear 24 to rotate. A rotating column 26 is rotatably connected through both ends of the support frame 19. A third bevel gear 27 is fixedly connected to one end of each rotating column 26. The third bevel gear 27 meshes with the top second bevel gear 24. The rotation of the second bevel gear 24 drives the rotation of the rotating column 26. Both ends of the base 1 are fixedly connected to the support platform 18. The top of the support platform 18 is fixedly connected to the second frame 31. One end of the second frame 31 is rotatably connected to the second fan blade rod 29. One end of the second fan blade rod 29 and the other end of the rotating column 26 are fixedly connected to the synchronous pulley 28. A synchronous belt 30 is provided between the synchronous pulleys 28 at the same end. The rotation of the rotating column 26 drives the second fan blade rod 29 to rotate through the synchronous pulley 28 and the synchronous belt 30, blowing out cold air from both sides to cool the mold with air cooling, combined with water cooling for efficient cooling.

[0022] Working principle: Close valve 12 and start circulating pump 33; circulating pump 33 draws low-temperature coolant from water tank 11 through the transmission pipe at the input end, delivers it to connecting pipe 9 through the output end, and continuously injects it into the sealed cavity formed by lower mold 2 and lower mold cavity 4; until the coolant completely covers the first heat sink 5, the second heat sink 6, and the turbulence holes 7 on the four sides of the lower mold cavity 4, valve 12 is opened to allow the coolant to enter circulation. High-temperature molten metal is injected into the lower mold cavity 4 through the pouring hole at the top of upper mold 3; after absorbing the heat from the molten metal, the lower mold cavity 4 quickly transfers the heat to the first heat sink 5 and the second heat sink 6 through the cavity wall, using the expanded contact area of ​​the heat sinks to accelerate heat conduction; circulating pump 33 continuously drives the coolant flow, and when the coolant flows through the turbulence holes 7, the turbulence holes... 7. The forced change of the liquid flow direction creates a violent disturbance, enhancing the heat exchange effect. The high-temperature coolant, after absorbing heat, flows back to the water tank 11 through the return pipe 10. Simultaneously, the servo motor 20 on the fixed plate 13 is started, and its output end drives the first fan blade rod 21 and the first bevel gear 23 fixed on the outer ring to rotate synchronously. When the first fan blade rod 21 rotates, it blows cold air into the water tank 11 to quickly cool the returning high-temperature coolant. The rotation of the first bevel gear 23 drives the connecting column 25 and the top second bevel gear 24 to rotate synchronously. The rotation of the top second bevel gear 24 drives the two rotating columns 26 to rotate synchronously. The rotation of the rotating columns 26 is transmitted through the synchronous pulley 28 and the synchronous belt 30, driving the second fan blade rod 29 to rotate, blowing cold air from both sides of the mold to cool the outer wall of the mold, forming a "water cooling + The cooling system uses a combination of air and air to dissipate heat. When processing castings of different specifications, the circulating pump 33 is turned off first, allowing all the coolant to flow back to the water tank 11. The sliding rod 17 is then manually pulled outwards, causing the limiting post 15 to slide outwards from the fixed frame 14. At this time, the spring 16 on the outer ring of the sliding rod 17 is compressed. When the limiting post 15 has completely slid out of the limiting grooves 8 at both ends of the lower mold cavity 4, the limiting of the lower mold cavity 4 is released, and the old lower mold cavity 4 is removed. After replacing the old lower mold cavity 4, the sliding rod 17 is released, and the spring 16 returns to its original position, pushing the limiting post 15 into the limiting groove 8 of the new lower mold cavity 4, thus completing the rapid locking.
