For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] A quick cooling mold base for a sand box casting wax injection machine, such as Figures 1 to 4As shown, it includes a base body 1, a plurality of special-shaped protrusion structures 2 are provided on one side of the base body, and a platform structure 3 is provided on the other side. A cooling water inlet 4 is provided on one side of the base body, and a platform side cooling water outlet 5 and a special-shaped protrusion side cooling water outlet 6 are provided on the other side. At least one platform side cooling water channel 7 and at least one special-shaped protrusion side cooling water channel 8 are provided in the base body, one side of the platform side cooling water channel is connected to the cooling water inlet, and the other side is connected to the platform side cooling water outlet, and one side of the special-shaped protrusion side cooling water channel is connected to the cooling water inlet, and the other side is connected to the special-shaped protrusion side cooling water outlet.

[0028] The cooling water channel on the platform side is parallel to the platform surface, and the cooling water channel on the special-shaped protrusion side matches the shape of the special-shaped protrusion structure, that is, the distance between the cooling water channel on the special-shaped protrusion side, which is located on the inner side of the special-shaped protrusion structure, and the outer surface of the special-shaped protrusion structure is consistent. At the same time, the distance between the cooling water channel on the special-shaped protrusion side, which is not located on the inner side of the special-shaped protrusion structure, and the surface on the side of the seat where the special-shaped protrusion structure is located, is consistent. The cooling water inlet is provided with an inlet pipe 9, and the cooling water outlet on the platform side and the cooling water outlet on the special-shaped protrusion side are both provided with outlet pipes 10. Under normal circumstances, plugs are installed on the inlet pipe and each outlet pipe. When needed, the plugs are removed and the water pipes are connected. Usually, the inlet pipe and the outlet pipe are provided with connecting flanges or connectors to facilitate connection with external water pipes.

[0029] When the quick cooling mold base is used, according to actual needs, the platform structure side can be selected to face the mold side, or the special-shaped protrusion structure side can be selected to face the mold side. The water inlet pipe is connected to the water supply pipe, and the circulating cooling water enters the seat body through the water inlet pipe. When the platform structure side is selected to face the mold, the return pipe is connected to the outlet pipe of the cold water outlet on the platform side, so that the circulating cooling water can effectively cool the platform structure part at a position close to the platform structure. When the special-shaped protrusion structure side is selected to face the mold, the return pipe is connected to the outlet pipe of the cooling water outlet on the special-shaped protrusion side, so that the circulating cooling water can effectively cool the special-shaped protrusion structure part at a position close to the special-shaped protrusion structure. For the production of large workpieces, the mold and mold base structure are relatively large in size. This cooling method can greatly shorten the cooling time and effectively improve production efficiency.

[0030] Preferably, the distance h1 between the portion of the cooling water channel on the side of the special-shaped protrusion located on the inner side of the special-shaped protrusion structure and the outer surface of the special-shaped protrusion structure is consistent with the distance h2 between the portion of the cooling water channel on the side of the special-shaped protrusion located not on the inner side of the special-shaped protrusion structure and the surface of the seat body on the side where the special-shaped protrusion structure is located. That is, when the values ​​of h1 and h2 are the same, the cooling effect of the cooling water on the side of the special-shaped protrusion tends to be uniform, so that the mold can be cooled evenly and quickly.

[0031] To further improve the uniformity of cooling performance, in an optional embodiment, the cooling water channels on the side of each special-shaped protrusion are arranged at equal intervals in the horizontal direction within the cross-sectional range of the base body. The cooling water channels on the side of each platform are arranged at equal intervals in the horizontal direction within the cross-sectional range of the base body. Both ends of each channel converge at the corresponding water inlet and outlet, respectively. In another optional embodiment, the cooling water channel on the side of the special-shaped protrusion can be designed as a meandering structure, so that the cooling water covers more positions of the cross-sectional area where the channel is located, thereby improving the cooling effect. Similarly, the cooling water channel on the platform side can also be designed as a meandering structure.

[0032] In an optional embodiment, each of the special-shaped protrusion structures can be detachably mounted on the base. Specifically, the special-shaped protrusion structure includes a main body 11 and connecting wings 12 on both sides of the main body. The base is provided with a mounting groove 13 for mounting the special-shaped protrusion structure, and the connecting wings are fixed to the base by a detachable connecting piece. Usually, the outer surface of the connecting wing is flush with the surface of the side of the base (the side where the mounting groove on the base is located). When the special-shaped protrusion structure is fixed to the mounting groove, the connecting wing is immersed in the mounting groove, and the liquid passage 15 in the special-shaped protrusion structure is connected with the special-shaped protrusion side cooling water channel on the base, that is, the special-shaped protrusion side cooling water channel is designed with two interfaces 16 on the bottom surface of the mounting groove, and the two ports 17 of the liquid passage channel in the special-shaped protrusion structure are respectively connected with the above interfaces, that is, the special-shaped protrusion side cooling water channel is connected. In order to improve the sealing between the special-shaped protrusion structure and the base and prevent the cooling water from overflowing, a sealing member 14 can be provided between the special-shaped protrusion structure and the base. As an example, the sealing member can be a sealing ring. A special-shaped protrusion structure of required specifications can be installed in the corresponding installation groove as needed (for example, a special-shaped protrusion structure of corresponding shape or corresponding thickness can be selected as needed), which has a higher matching degree with the applied mold, has fewer limitations in use, and further improves versatility.

[0033] The invention can adapt to different application needs by designing different structural forms on both sides of the seat body, reducing the limitation of use and improving the versatility. In addition, by providing a platform side cooling water channel and a special-shaped protrusion side cooling water channel in the seat body, the two channels for cooling water circulation can cool the platform structure side and the special-shaped protrusion structure side respectively, shortening the cooling time, especially for large molds, the cooling operation efficiency can be significantly improved.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
