Specific implementation
[0019] Please refer to Figures 1-4A rapid prototyping mold for manufacturing cast steel parts includes a support frame 1 and a mold body 4. Circulation transfer components 2 are installed on both the left and right sides of the support frame 1. Each circulation transfer component 2 includes a pump 203. The inlet end of the pump 203 is connected to a suction pipe 201. By setting the suction pipe 201, the inlet end of the pump 203 can be connected to the heat transfer oil inside the support frame 1, allowing the oil to enter through the suction pipe 201 when the pump 203 is working. A branch pipe 204 is installed at the outlet end of the pump 203, and the other end of the branch pipe 204 is connected to a second telescopic hose 205. A hollow horizontal pipe 11 is provided on the outer ring of the mold body 4. A spray hole 12 is opened at the bottom of the hollow horizontal pipe 11. By setting the hollow horizontal pipe 11 and the spray hole 12, multiple... A spray nozzle 12 is distributed on the hollow horizontal tube 11, so that the surface of the mold body 4 can be uniformly sprayed with heat conduction treatment when the heat conduction oil is transferred. A first telescopic hose 10 is connected between two adjacent hollow horizontal tubes 11. By setting the first telescopic hose 10, the two hollow horizontal tubes 11 can still be connected when the distance between two adjacent hollow horizontal tubes 11 changes, so that the heat conduction oil can be uniformly transferred to multiple hollow horizontal tubes 11. A heat dissipation fin plate 3 is fixedly embedded at the bottom of the inner cavity of the support frame 1. By setting the heat dissipation fin plate 3, the heat conduction oil with residual heat in the support frame 1 can be dissipated, which is conducive to reducing the temperature of the heat conduction oil. A heat conduction thin plate 6 is installed on both the front and back surfaces of the support frame 1. A heat exchange bend 7 is fixedly installed on the outer side of the heat conduction thin plate 6.
[0020] Please see Figure 1 and Figure 3 The infusion pump 203 is bolted to the support frame 1, and the end of the suction tube 201 away from the infusion pump 203 extends to the bottom of the inner cavity of the support frame 1;
[0021] Please see Figure 1 and Figure 3 The outlet end of the infusion pump 203 is connected to a three-way pipe 202, and there are two branch pipes 204, both of which are connected to the three-way pipe 202. By setting the three-way pipe 202, the connection between the two branch pipes 204 and the outlet end of the infusion pump 203 can be met at the same time.
[0022] Please see Figure 1 and Figure 3 The end of the second telescopic hose 205 away from the branch pipe 204 is connected to the inner cavity of the hollow horizontal pipe 11. By setting the second telescopic hose 205, the requirement for the branch pipe 204 to connect with the hollow horizontal pipe 11 can still be met when the hollow horizontal pipe 11 is displaced. There are four hollow horizontal pipes 11 and four first telescopic hoses 10.
[0023] Please see Figure 1 and Figure 3 The bottom of the hollow horizontal tube 11 is fixedly connected to a guide frame 8, and one end of the guide frame 8 extends through to the outside of the support frame 1.
[0024] Please see Figure 1 and Figure 3 The guide frame 8 and the load-bearing frame 1 are connected to slide and sealed. By setting the guide frame 8, the displacement of the hollow horizontal tube 11 can be guided to ensure the stability of the hollow horizontal tube 11. The top of the guide frame 8 is fixedly embedded with a damping pad 9. By setting the damping pad 9, the contact friction between the guide frame 8 and the hollow horizontal tube 11 can be increased, thereby preventing the guide frame 8 from moving randomly.
[0025] Please see Figure 1 and Figure 4 The end of the heat dissipation fin 3 away from the support frame 1 extends to the outside of the support frame 1, and one end of the heat exchange bend 7 is connected to the cold water source through an external water pump.
[0026] Please see Figure 3 The surface of the support frame 1 is provided with an installation groove 5 for use with the heat-conducting thin plate 6. By setting the installation groove 5, the installation space requirements of the heat-conducting thin plate 6 and the heat exchange bend 7 can be met.
[0027] In practical applications, to prevent impurities in the heat transfer oil from entering the infusion pump 203, a filter screen is fixedly installed at the bottom of the suction pipe 201.
[0028] In practical applications, in order to increase the contact area between the heat exchanger bend 7 and the heat-conducting thin plate 6, the heat exchanger bend 7 can be partially embedded in the heat-conducting thin plate 6.
[0029] In practical applications, in order to reduce the natural evaporation of the oil and prevent external dust and impurities from entering the heat transfer oil, and to prevent high-temperature molten metal from coming into contact with the heat transfer oil, baffles can be placed on the top of the support frame 1 and the outside of the mold body 4 to achieve the protective effect.
[0030] In use, all components are in their initial state. First, according to the specifications of the mold body 4, the hollow horizontal tube 11 at the corresponding position is flexibly driven to move. With the assistance of the guide frame 8 and the damping pad 9, the hollow horizontal tube 11 is kept stationary in a suitable position. The first telescopic hose 10 is stretched or compressed, and the second telescopic hose 205 is stretched or compressed. Then, the mold body 4 is lowered and placed into the support frame 1, with its lower end immersed in the heat transfer oil in the support frame 1. When cooling is required after pouring, the infusion pump 203 is controlled to work, so that the oil in the support frame 1 is transferred through the suction pipe 201 and the three-way pipe 20 2. The oil is transmitted through the branch pipe 204, the second telescopic hose 205, the hollow horizontal pipe 11, the first telescopic hose 10, and the spray hole 12. Finally, it is evenly sprayed onto the mold body 4 through the spray hole 12. Under the action of gravity, the oil will absorb the surface temperature of the mold body 4 and gradually move downward, achieving the purpose of circulating and uniform cooling. At the same time, the heat dissipation fins 3 dissipate the heat in the oil to the outside, while the cold water from the outside circulates through the heat exchange bend 7 and exchanges heat with the oil through the heat-conducting thin plate 6, which can also achieve the purpose of auxiliary cooling. Moreover, the heat-conducting oil has a high boiling point and a low freezing point, making it difficult to boil at high temperatures and difficult to solidify at low temperatures, thus having a wider range of applications.
[0031] In summary, this rapid prototyping mold for manufacturing cast steel parts, by incorporating a circulating transmission component 2, heat dissipation fins 3, heat-conducting thin plates 6, heat exchange bends 7, first telescopic hoses 10, hollow horizontal pipes 11, and nozzles 12, solves the problems of the generally poor heat dissipation effect and uniformity of air-cooled systems in existing molding molds, while water-cooled systems have high wiring costs and a large user base, are prone to boiling at high temperatures and condensation at low temperatures, and have a limited overall applicability and certain limitations.
