Description

Technical Field

[0001] This utility model relates to the field of molds, specifically a casting mold with a cooling structure. Background Technology

[0002] Casting molds are the core tools used in the casting process to form the shape of castings. They are essentially hollow cavity structures that contain liquid materials and control their cooling process to ultimately obtain parts that conform to the geometry of the mold cavity.

[0003] To improve the cooling rate of castings, most existing casting molds incorporate cooling structures. For example, utility model patent application number 2024209350404 discloses a casting mold with a cooling structure. This mold transfers heat from the mold liquid in the mold body through the cooperation of heat-conducting pillar two and heat-conducting pillar one. At the same time, a water pump and a fan are activated to quickly cool the mold body. The cooling liquid in the cooling tank is sprayed onto the inner wall of the cooling tank through atomizing nozzles by the water pump. The atomized cooling liquid greatly increases the contact area with the inner wall of the cooling tank, thereby more effectively removing heat from the mold body and the heat-conducting pillar one.

[0004] However, this mold can only cool the lower mold, which can easily cause uneven cooling of the casting and a large temperature difference in the casting, which can easily cause cracking or deformation. Improvement is needed. Utility Model Content

The sides of the upper water distribution trough and the upper water collection trough are respectively provided with water inlets and water outlets, and the water inlets and water outlets are respectively connected to the upper water supply pipe and the upper water return pipe through connecting pipes.

[0011] Furthermore, the upper mold base has upper grooves at both ends on the outer side of the upper core, and one end of the upper water supply pipe and the upper water return pipe is located in the upper groove.

[0012] Furthermore, the second water cooling mechanism includes a lower water distribution trough and a lower water collection trough disposed inside both ends of the lower core. Multiple water guide pipes are connected between the lower water distribution trough and the lower water collection trough. The water guide pipes are close to the inner top surface of the cavity. The sides of the lower water distribution trough and the lower water collection trough are respectively provided with water inlets and water outlets, and the water inlets and water outlets are respectively connected to the lower water supply pipe and the lower water return pipe through connecting pipes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, a casting mold with a cooling structure includes an upper mold base 1 and a lower mold base 2. An upper core 3 and a lower core 4 are respectively installed inside the upper mold base 1 and the lower mold base 2, and a cavity is formed between the upper core 3 and the lower core 4.

[0024] The upper mold base 1 has an upper water supply pipe 5 and an upper water return pipe 6 at its two ends respectively. The upper core 3 has a water cooling mechanism 1 inside. The two ends of the water cooling mechanism 1 are connected to the upper water supply pipe 5 and the upper water return pipe 6 respectively. The water cooling mechanism 1 includes an upper water distribution groove 11 and an upper water collection groove 12 located in the upper part of both ends of the upper core 3. The bottom of the upper water distribution groove 11 is connected to a plurality of water distribution pipes 13 of different lengths. The bottom of the water distribution pipes 13 is symmetrically connected to two branch pipes 14 that are wound around the outside of the cavity. The ends of the branch pipes 14 are connected to the upper water collection groove 12. The sides of the upper water distribution groove 11 and the upper water collection groove 12 are respectively provided with water inlets and water outlets, and the water inlets and water outlets are respectively connected to the upper water supply pipe 5 and the upper water return pipe 6 through connecting pipes. The upper mold base 1 has upper grooves on the outside of the upper core 3 at both ends. One end of the upper water supply pipe 5 and the upper water return pipe 6 is located in the upper groove.

[0025] Connecting the upper water supply pipe 5 and the upper water return pipe 6 to the cold water circulation system can achieve cooling of the sides of the cavity.

[0026] The lower mold base 2 is provided with a lower water supply pipe 7 and a lower water return pipe 8 at both ends. The lower core 4 is provided with a water cooling mechanism II. The two ends of the water cooling mechanism II are connected to the lower water supply pipe 7 and the lower water return pipe 8, respectively. The water cooling mechanism II includes a lower water distribution groove 15 and a lower water collection groove 16 disposed inside both ends of the lower core 4. A plurality of water guide pipes 17 are connected between the lower water distribution groove 15 and the lower water collection groove 16. The water guide pipes 17 are close to the inner top surface of the cavity. The sides of the lower water distribution groove 15 and the lower water collection groove 16 are provided with water inlets and water outlets, respectively. The water inlets and water outlets are connected to the lower water supply pipe 7 and the lower water return pipe 8 through connecting pipes, respectively. The lower mold base 2 is provided with a lower groove on the outside of the lower core 4 at both ends. One end of the lower water supply pipe 7 and the lower water return pipe 8 is located in the lower groove.

[0027] Connecting the lower water supply pipe 7 and the lower water return pipe 8 to the cold water circulation system can achieve cooling of the top surface of the cavity.

[0028] The lower core 4 has a fixing groove on its top surface. A push plate 18 is provided inside the fixing groove. A push rod 19 is fixed at the bottom center of the push plate 18, passing through the lower core 4 and the lower mold base 2. A temperature sensor 20 is installed on the bottom surface of the push plate 18. The push rod 19 is a hollow rod.

[0029] The push plate 18 increases the contact area with the casting product. The casting product directly contacts the push plate 18, and heat is transferred to the push plate 18. By installing a temperature sensor 20 at the bottom of the push plate 18, the temperature of the casting product can be indirectly measured. The push rod 19 is a hollow rod, and the wiring of the temperature sensor 20 can be hidden inside the push rod 19.

[0030] The ends of the upper water supply pipe 5 and the lower water supply pipe 7 are both connected to heating pipes 9, and multiple sets of electric heating tubes 10 are installed inside the heating pipes 9.

[0031] By setting heating tube 9 to heat the water entering the upper water tank 11 and the lower water tank 15, the risk of increased internal stress and cracks caused by excessive temperature difference can be prevented in the early stage of casting. By gradually turning off the number of heating tubes 10, the water temperature entering the upper water tank 11 and the lower water tank 15 can be gradually reduced, thereby making the cooling of the casting product relatively uniform and improving the product quality.

[0032] In practical use, the temperature sensor 20 and the heating tube 9 are connected to an external power supply and a PLC controller. In the early stage of casting, multiple sets of electric heating tubes 10 heat the cold water to a warm water temperature of about 50°C. By circulating the warm water, the casting product is cooled, reducing internal stress, preventing cracking or deformation, and improving physical properties and durability. Through the cooperation of water cooling mechanism one and water cooling mechanism two, the uniformity and efficiency of casting cooling can be improved. As the product temperature decreases, the number of electric heating tubes 10 is gradually turned off, so that the cooling of the casting product is relatively uniform and the product quality is improved.
