[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1 and Figure 2The utility model provides an embodiment: a die-casting device for producing metal parts, including a casing 1, a top plate 2 is fixedly connected to the top of the casing 1, a hydraulic rod 3 is fixedly connected inside the top plate 2, an upper mold 4 is fixedly connected to the output end of the hydraulic rod 3, a lower mold 5 is fixedly connected to the top of the casing 1, a limiting column 8 is fixedly connected inside the casing 1, an electric push rod 6 is fixedly connected inside the casing 1, a support plate 7 is fixedly connected to the output end of the electric push rod 6, the support plate 7 is slidably connected to the outer wall of the limiting column 8, and a reset component is provided on the outer wall of the limiting column 8, and the reset component is used to reset the support plate 7 to the inside of the casing 1 , the top of the support plate 17 is rotatably connected with a connecting rod 10, the top of the support plate 17 is fixedly connected with a top column 11, the outer wall of the top column 11 is slidably connected with a support plate 2 12, the top of the support plate 2 12 is fixedly connected with a top column 2 13, the outer wall of the top column 11 is sleeved with a second spring 14, the reset assembly includes a first spring 9, the first spring 9 is sleeved on the outer wall of the limit column 8, one end of the first spring 9 is fixedly connected to the inside of the casing 1, the other end of the first spring 9 is fixedly connected to the top of the support plate 17, one end of the second spring 14 is fixedly connected to the inside of the casing 1, and the other end of the second spring 14 is fixedly connected to the top of the support plate 2 12;
[0032] Specifically, the metal is heated at a high temperature to make it fluid, and then injected into the mold. The mold usually consists of two parts, the lower mold 5 provides a shape for the metal, and the upper mold 4 is used to compact the metal so that it can tightly fill the mold space. After the metal is injected, the role of the hydraulic rod 3 becomes particularly important. It extends through the output end to drive the upper mold 4 to move downward and fit tightly with the lower mold 5. This process ensures that the metal can be fully compacted inside the mold to form the required part shape. When the metal is cooled and solidified in the mold, the next key step is to use the electric push rod 6. The output end of the electric push rod 6 extends to drive the support plate 1 7 to rise. This support plate 1 7 is connected between the upper mold 4 and the top column 2 13. Its rising movement will push the top column 2 13 out. Subsequently, as the support plate 1 7 continues to rise, one end of the connecting rod 10 will contact the casing 1, which causes the other end of the connecting rod 10 to lift up. This lifting action will further drive the support plate 2 12 to rise. The movement of these two support plates cooperates, so that the top column 11 can push the part out of the mold.
[0033] Reference Figure 3 and Figure 4A box body 15 is fixedly connected to one side of the casing 1, a sealing cover 16 is provided on the top of the box body 15, a cooling fan 20 is provided inside the box body 15, a heat dissipation port 21 is provided inside the box body 15, a water outlet pipe 17 is fixedly connected to the inside of the box body 15, one end of the water outlet pipe 17 is fixedly connected to a water pump 18, an output end of the water pump 18 is fixedly connected to one end of the water outlet pipe 17, a coil 19 is fixedly connected to the output end of the water pump 18, an outer wall of the coil 19 is passed through the inside of the lower mold 5, and the other end of the coil 19 is fixedly connected to the inside of the box body 15, a partition 22 is fixedly connected to the inside of the box body 15, a semiconductor refrigeration plate 23 is fixedly connected to one side of the partition 22, a temperature conduction plate 24 is fixedly connected to one side of the semiconductor refrigeration plate 23, and a heat dissipation column 25 is fixedly connected to the other side of the semiconductor refrigeration plate 23;
[0034] Specifically, first, the water pump 18, as the core component of the cooling system, is responsible for driving the flow of cooling water. The input end of the water pump 18 is connected to the inside of the box 15 through the outlet pipe 17 to extract the cooling water in the box 15. Then, the water pump 18 pumps the cooling water into the coil 19 to achieve the recycling of the cooling water. Next, when the cooling water passes through the lower mold 5 inside the coil 19, it dissipates heat and cools it. This process helps to maintain the stable operation of the production equipment and prevent the equipment from overheating. After passing through the other end of the coil 19, the cooling water returns to the inside of the box 15 to achieve recycling. In addition, the semiconductor refrigeration plate 23 plays an important role in the cooling process. The cooling surface transfers the cold to the cooling water through the heat conduction plate 24 to achieve cooling of the cooling water. At the same time, the heat dissipation surface of the semiconductor refrigeration plate 23 increases the contact area with the air through the conduction of the heat dissipation column 25, thereby improving the heat dissipation effect. Finally, the heat dissipation fan 20 inhales external air and blows the air through the heat dissipation column 25 for heat dissipation. The hot air after heat dissipation is discharged through the heat dissipation port 21 to ensure the stability of the internal temperature of the equipment.
[0035] Working principle: When the die-casting device for producing metal parts is used, the molten metal is first injected into the lower mold 5, and then the output end of the hydraulic rod 3 extends to drive the upper mold 4 to press down and snap into the lower mold 5. Then the input end of the water pump 18 draws out the cooling water inside the box 15 through the outlet pipe 17, and then pumps it into the coil 19 through the output end of the water pump 18, so that the cooling water passes through the lower mold 5 to dissipate heat and cool it. Then the cooling water returns to the box 15 through the other end of the coil 19 to circulate the cooling water. At the same time, the cooling surface of the semiconductor refrigeration plate 23 is cooled and conducted to the cooling water through the temperature conduction plate 24. The heat dissipation surface of the semiconductor refrigeration plate 23 increases its contact area with the air through the conduction of the heat dissipation column 25, and then the heat dissipation fan 20 draws in external air, allowing the air to blow through the heat dissipation column 25 for heat dissipation, and then the hot air is discharged through the heat dissipation port 21. When the metal is cooled, the output end of the electric push rod 6 extends to drive the support plate 1 7 to rise, and the support plate 1 7 drives the support plate 2 12 to push out the top column 2 13, and then in the process of the support plate 1 7 continuing to rise, one end of the connecting rod 10 contacts the casing 1 to lift the other end of the connecting rod 10, thereby driving the support plate 2 12 to continue to lift and further push the parts out through the top column 11.
