Description

Technical Field

[0001] This utility model belongs to the field of die casting mold technology, and specifically relates to a die casting mold with good cooling effect. Background Technology

[0002] Die casting molds are a method of casting liquid forging, a process completed on a dedicated die casting and forging machine. Its basic process is as follows: the molten metal is first cast and filled into the cavity of the mold at low or high speed. The mold has a movable cavity surface. As the molten metal cools, it is pressurized and forged, which not only eliminates shrinkage cavities and porosity defects in the blank, but also makes the internal structure of the blank reach the forged state of broken grains.

[0003] Currently, in order to improve the cooling speed of die-casting molds, most methods involve spraying cooling water onto the die-casting mold to accelerate the dissipation of heat. For example, a die-casting mold for an LED street light housing heat sink is disclosed in Chinese Patent Publication No. CN214133916U. However, since the sprayed cooling water only contacts the surface of the die-casting mold, the heat inside the die-casting mold does not dissipate quickly, resulting in poor cooling effect. Utility Model Content

[0004] The purpose of this invention is to provide a die-casting mold with good cooling effect, which solves the problem that the heat inside the die-casting mold does not dissipate quickly because the sprayed cooling water only comes into contact with the surface of the die-casting mold, resulting in poor cooling effect.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A die-casting mold with good cooling effect includes a water tank. A first column is fixedly connected to the bottom of the inner wall of the water tank. A lower mold is fixedly connected to the upper surface of the first column. An upper mold is fitted onto the upper surface of the lower mold. Through holes are opened inside the lower mold and the upper mold. A heat-conducting column is fixedly connected to the inner wall of the through hole. Heat-conducting plates are fixedly connected to the left and right sides of the heat-conducting column, the left and right sides of the lower mold, and the left and right sides of the upper mold.

[0008] The present invention is further configured such that the water spraying mechanism includes an inlet pipe, a water pump, an outlet pipe, an annular pipe, a distribution pipe, a connecting pipe, and a nozzle. The surface of the inlet pipe is fixedly connected to the inner wall of the circular hole. The bottom of the water pump is fixedly connected to the upper surface of the support plate.

[0009] The present invention is further configured such that filter screens are fixedly connected to the side of the support plate, the upper surface of the water tank, and the surface of the lower mold. The filter screens are stainless steel wire mesh with a mesh size of 0.5 mm.

[0010] The present invention is further configured such that mounting holes are provided on both the left and right sides of the water tank, and copper pillars are fixedly connected to the inner walls of the mounting holes. Water-cooling plates are fixedly connected to one end of the copper pillars and both the left and right sides of the water tank.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figures 1 to 13 As shown, a die-casting mold with good cooling effect includes a water tank 1. A first column 2 is fixedly connected to the bottom of the inner wall of the water tank 1. A lower mold 3 is fixedly connected to the upper surface of the first column 2. An upper mold 4 is fitted onto the upper surface of the lower mold 3. Through holes 5 are opened inside the lower mold 3 and the upper mold 4. Heat-conducting columns 6 are fixedly connected to the inner walls of the through holes 5. Heat-conducting plates 7 are fixedly connected to the left and right sides of the heat-conducting columns 6, the left and right sides of the lower mold 3, and the left and right sides of the upper mold 4. 7. A groove 8 is provided on the side. A heat insulation plate 9 is fixedly connected to the upper surface of the upper mold 4. A blower mechanism 10 is fixedly connected to the upper surface of the heat insulation plate 9. An air outlet 11 is provided inside the heat insulation plate 9. A support plate 12 is fixedly connected to the upper surface of the water tank 1. A round hole 13 is provided inside the support plate 12. A water spraying mechanism 14 is fixedly connected to the inner wall of the round hole 13 and the upper surface of the support plate 12. A second column 15 is fixedly connected to the bottom of the water spraying mechanism 14 and the upper surface of the support plate 12.

[0033] The blower mechanism 10 includes a three-way pipe 101, an air intake shroud 102, a housing 103, and a cooling fan 104. The top end of the three-way pipe 101 is fixedly connected to the bottom end of the air intake shroud 102. The inner wall of the air intake shroud 102 is fixedly connected to the surface of the cooling fan 104. Both the left and right ends of the three-way pipe 101 are fixedly connected to the sides of the housing 103. The upper surface of the heat insulation plate 9 is fixedly connected to the bottom of the housing 103.

[0034] The water spraying mechanism 14 includes an inlet pipe 141, a water pump 142, an outlet pipe 143, an annular pipe 144, a distribution pipe 145, a connecting pipe 146, and a nozzle 147. The surface of the inlet pipe 141 is fixedly connected to the inner wall of the circular hole 13. The bottom of the water pump 142 is fixedly connected to the upper surface of the support plate 12. The inlet end of the water pump 142 is fixedly connected to one end of the inlet pipe 141, and the outlet end of the water pump 142 is fixedly connected to one end of the outlet pipe 143. The other end of 3 is fixedly connected to the side of the annular pipe 144. The upper and lower ends of the water distribution pipe 145 are fixedly connected to the inner wall of the annular pipe 144. The side of the water distribution pipe 145 and the side of the annular pipe 144 are fixedly connected to one end of the connecting pipe 146. The other end of the connecting pipe 146 is fixedly connected to the water inlet end of the nozzle 147. The upper surface of the second column 15 is fixedly connected to the bottom of the annular pipe 144. The nozzle 147 is located between the heat-conducting plate 7 and the connecting pipe 146.

[0035] A filter screen 16 is fixedly connected to the side of the support plate 12, the upper surface of the water tank 1, and the surface of the lower mold 3. The filter screen 16 is a stainless steel wire mesh with a pore size of 0.5mm.

[0036] It should be noted that both the heat-conducting pillar 6 and the heat-conducting plate 7 are made of aluminum alloy. The heat-conducting pillar 6 can quickly transfer the heat in the lower mold 3 and the upper mold 4 to the heat-conducting plate 7. At the same time, by setting the groove 8 on the heat-conducting plate 7, the contact surface between the heat-conducting plate 7 and the cooling water and air can be increased. Thus, when the heat-conducting plate 7 is cooled by air and water spray, the heat in the heat-conducting plate 7 can be quickly dissipated.

[0037] The heat insulation plate 9 is made of graphite-based composite material. The heat insulation plate 9 can prevent the heat in the upper mold 4 from being transferred to the box 103, so that the air in the box 103 will not be heated by the upper mold 4. When the cooling fan 104 in the air inlet shroud 102 is turned on, the cooling fan 104 generates a downward airflow at the air outlet 11 and performs air cooling on the heat conduction plate 7.

[0038] When the water pump 142 is turned on, the cooling water in the water tank 1 is sprayed out through the nozzle 147 by the water pump 142, and the cooling water sprayed out by the nozzle 147 sprays water to cool the heat conduction plate 7. At the same time, the cooling water dripping from the heat conduction plate 7 will be filtered through the filter screen 16 and then directly enter the water tank 1 for reuse. The filter screen 16 filters impurities in the cooling water and can effectively prevent foreign objects from entering the water tank 1.

[0039] like Figures 1 to 4 As shown, mounting holes 17 are provided on both the left and right sides of the water tank 1. Copper pillars 18 are fixedly connected to the inner walls of the mounting holes 17. Water cooling plates 19 are fixedly connected to one end of the copper pillars 18 and both the left and right sides of the water tank 1.

[0040] It should be noted that the flow channels inside the water-cooled plate 19 are connected to the radiator and the circulation pump respectively. The radiator cools the cooling water, and the circulation pump makes the low-temperature cooling water after being cooled by the radiator circulate in the water-cooled plate 19. At this time, the temperature of the copper pillar 18 can be reduced through the water-cooled plate 19, and the low-temperature copper pillar 18 can cool the cooling water in the water tank 1. In this way, the recovered cooling water will not be too hot, which will reduce the cooling effect of the water spray mechanism 14 on the heat conduction plate 7.

[0041] The working principle of this utility model is as follows: When cooling the upper mold 4 and the lower mold 3, the heat can be quickly transferred from the lower mold 3 and the upper mold 4 to the heat-conducting plate 7 through the heat-conducting column 6. Then, by opening the cooling fan 104 in the air inlet shroud 102, a downward airflow is generated at the air outlet 11, which cools the heat-conducting plate 7. At the same time, by turning on the water pump 142, the cooling water in the water tank 1 is sprayed out through the nozzle 147, and the cooling water sprayed out by the nozzle 147 cools the heat-conducting plate 7. At this time, through air cooling and water cooling, the heat inside the heat-conducting plate 7 is cooled. The heat can be dissipated quickly, and the heat-conducting plate 7 can continuously and efficiently absorb the heat in the lower mold 3 and the upper mold 4, thereby allowing the heat in the lower mold 3 and the upper mold 4 to dissipate quickly. At the same time, the cooling water dripping from the heat-conducting plate 7 will be filtered through the filter screen 16 and directly enter the water tank 1 for reuse. Then, the low temperature cooling water circulating in the water-cooling plate 19 can lower the temperature of the copper pillar 18, and the low temperature copper pillar 18 can cool the cooling water in the water tank 1. At this time, the recovered cooling water will not be too hot, which will reduce the cooling effect of the water spray mechanism 14 on the heat-conducting plate 7.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
