[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a wax mold cooling device for lost-wax casting;

[0027] Example 1:

[0028] To facilitate the disassembly and maintenance of the cooling components, guide pillars 19 are fixedly installed on the side surface of the fixed mold core 1, and guide holes 28 are provided on the side surface of the movable mold core 2. Cooling cavities 17 are formed on the inner surfaces of the fixed mold core 1 and the movable mold core 2. A frame 9 is slidably connected to the inner surface of the cooling cavity 17, and a cooling component is fixedly installed on the inner surface of the frame 9. Mold cavities 3 are formed on the side surfaces of the fixed mold core 1 and the movable mold core 2. A locking assembly is fixedly installed on the upper surfaces of the fixed mold core 1 and the movable mold core 2. The locking assembly includes: a fixed seat 6, an installation groove 7 on the upper surface of the fixed seat 6, and a through groove 8 on the side surface of the fixed seat 6. An installation block 10 is fixedly installed on the upper surface of the frame 9, and slots 11 are formed on both sides of the installation block 10. A movable rod 23 is slidably connected to the inner surface of the through groove 8. A pull plate 27 is fixedly installed on the side surface of the movable rod 23. A pressing block 25 is fixedly installed at the end of the movable rod 23 away from the pull plate 27. A return spring 24 is sleeved on the outer surface of the movable rod 23. A locking block 26 is fixedly installed at the end of the movable rod 23 near the pressing block 25. The guide post 19 is engaged with the guide hole 28. The locking block 26 is engaged with the slot 11. By pulling the pull plates 27 on both sides outward, the pressing block 25 on the movable rod 23 is moved outward to compress the return spring 24. This further causes the locking block 26 to disengage from the slots 11 on both sides of the mounting block 10, thereby disassembling and maintaining the cooling components inside the frame 9. This improves installation stability and makes cleaning, inspection and maintenance of the internal components of the cooling components simpler. When the cooling components need to be replaced, the entire module can be replaced quickly, thereby reducing downtime and improving work efficiency.

[0029] Example 2:

[0030] Based on Embodiment 1, to achieve continuous cooling within the cooling chamber 17, several fixing grooves 13 are provided on the side surface of the fixing plate 12. A condenser pipe 16 is engaged on the inner surface of each fixing groove 13. The fixing plate 12 is mounted on the bottom surface of the frame 9. Sliding grooves 14 are provided on both sides of the frame 9. Three wedge-shaped blocks 15 are fixedly installed on the lower surface of the frame 9. The wedge-shaped blocks 15 are trapezoidal in shape. A sliding rod 22 is fixedly installed on the inner side of the cooling chamber 17. Three dovetail grooves 21 are provided on the bottom surface of the cooling chamber 17. The sliding rod 22 is slidably connected to the sliding grooves 14, and the dovetail grooves 21 are engaged with the wedge-shaped blocks 15. A wax injection port 4 is provided at the connection between the lower surfaces of the fixed mold core 1 and the movable mold core 2. A liquid inlet pipe 5 is fixedly installed on the side surfaces of the fixed mold core 1 and the movable mold core 2. Two buffer spring seats 18 are fixedly installed on the bottom surface, and the buffer spring seats 18 are in contact with the bottom surface of the cooling cavity 17. A sealing rubber gasket 20 is provided at the connection between the condenser pipe 16 and the frame 9. Coolant is injected into the cooling cavity 17 through the injection pipe 5 to cool and solidify the wax mold in the mold cavity 3. When the coolant in the cooling cavity 17 cools the mold cavity 3 for a long time, the temperature of the coolant will rise with the use time. By connecting the condenser pipe 16 fixedly installed in the frame 9 with the wedge block 15 through the dovetail groove 21 and the slide rod 22 with the slide groove 14 into the cooling cavity 17, the coolant in the cooling cavity 17 is continuously cooled, so that the wax mold in the mold cavity 3 can be cooled evenly to achieve a faster curing effect and improve the demolding efficiency of the wax mold.

[0031] Working Principle: To ensure continuous cooling of the wax mold in the mold cavity 3 by the coolant in the cooling chamber 17, coolant is injected into the cooling chamber 17 through the injection pipe 5 to cool and solidify the wax mold in the mold cavity 3. During prolonged cooling of the mold cavity 3 by the coolant in the cooling chamber 17, the temperature of the coolant will rise over time. The condenser pipe 16, fixedly installed within the frame 9, is engaged with the wedge block 15 via the dovetail groove 21 and the slide rod 22 via the slide groove 14 within the cooling chamber 17, continuously cooling the coolant in the cooling chamber 17. This ensures uniform cooling of the wax mold in the mold cavity 3. The wax mold is cooled to achieve a faster curing effect and improve the demolding efficiency of the wax mold. In order to facilitate the disassembly and maintenance of the cooling component, by pulling the pull plates 27 on both sides outward, the pressing block 25 on the movable rod 23 is moved outward to compress the return spring 24, which further drives the locking block 26 to disengage from the slots 11 on both sides of the mounting block 10, thereby disassembling and maintaining the cooling component in the frame 9, improving installation stability, and making the cleaning, inspection and maintenance of the cooling component inside simpler. When the cooling component needs to be replaced, the entire module can be replaced quickly, thereby reducing downtime and improving work efficiency.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
