Description

Technical Field

[0001] The invention relates to the technical field of metal casting, and in particular to a cooling device for a metal casting mold. Background Art

[0002] Metal casting molds are special molds used for metal casting production. They are usually made of high-strength metal materials and can withstand the impact and pressure of high-temperature molten metal. The shape and size of the mold are designed according to the shape and size of the required casting parts to ensure that the metal parts can be accurately formed. During the casting process, the molten metal is injected into the mold cavity, and after cooling and solidification, a metal part with the same shape as the mold cavity is formed;

[0003] In the metal casting process, in order to improve processing efficiency, it is often necessary to cool the mold to speed up the cooling and solidification during casting. In water cooling, the heat of the mold is transferred to the cooling water, causing its temperature to change frequently. The temperature change will cause the solubility of calcium and magnesium ions to change, which is easy to cause calcium and magnesium ions to precipitate, thereby forming scale and affecting the water cooling effect. Therefore, we proposed a cooling device for metal casting molds. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a cooling device for a metal casting mold, comprising:

[0005] A mold, the mold having grooves on both upper and lower sides, and a bottom plate arranged at the bottom of the mold;

[0011] A filter assembly having an adsorption structure for adsorbing scale in the cooling water in the groove at the bottom of the mold;

[0012] The outer side surface of the cooling pipe is fixedly connected to the outer side surface of the mold, the inner side surface of the shell is fixedly connected to the outer side surface of the mold, and the cooling pipe is arranged at the interval between the shell and the mold, the surface of the water-drawing component is fixedly connected to the top of the groove at the bottom of the mold, the filter component is fixedly connected to the top of the bottom plate by bolts, and the filter component is arranged inside the groove at the bottom of the mold, the water-drawing component is started, the water-drawing component draws cooling water from the groove at the bottom of the mold, the cooling water enters the cooling pipe, cools down the surrounding of the mold, the temperature of the cooling water rises, and finally returns to the groove at the bottom of the mold, and then is filtered by the filter component and drawn by the water-drawing component again to realize circulating cooling, the cooling water inside the cooling pipe is always flowing, and can It can effectively reduce the adhesion of calcium and magnesium ions after precipitation, and avoid the adhesion of scale inside the cooling pipe due to the heating of cooling water. The spirally arranged cooling pipe can increase the circulation area of ​​cooling water in a limited space and enhance the cooling effect. Compared with the pipeline formed by connecting multiple pipes, the integrated structure of the cooling pipe spiral has a smooth and step-free inner wall, which can effectively reduce the adhesion of scale. After the cooling water is heated, the solubility of calcium and magnesium ions in it is reduced, and they are precipitated inside the groove at the bottom of the mold and adsorbed by the filter component, thereby reducing the content of calcium and magnesium ions circulating into the cooling pipe, avoiding the formation of scale on the inner wall of the cooling pipe, avoiding the blockage of the cooling pipe, and ensuring that the inner diameter of the cooling pipe will not be reduced due to the adhesion of scale, thereby maintaining the cooling effect for a long time.

[0013] Furthermore, the two ends of the cooling pipe are respectively fixedly connected with a first guide pipe and a second guide pipe, and the end surface of the first guide pipe is fixedly connected to the end of the cooling pipe away from the bottom plate, and the end surface of the second guide pipe is fixedly connected to the end of the cooling pipe close to the bottom plate, the end of the first guide pipe away from the cooling pipe extends to the inside of the groove at the bottom of the mold, and the end of the second guide pipe away from the cooling pipe extends to the inside of the groove at the bottom of the mold, and the first guide pipe and the second guide pipe are arranged opposite to each other at one end away from the cooling pipe, and the outer side surfaces of the first guide pipe and the second guide pipe are fixedly connected to the mold, cooling water circulates through the first guide pipe and the second guide pipe, and accumulates in the groove at the bottom of the mold, which can cool the bottom of the mold, and at the same time, the cooling water circulates in the groove at the bottom of the mold driven by the first guide pipe and the second guide pipe, which can effectively avoid the adhesion of scale.

[0014] Furthermore, a partition is fixedly connected to the top of the inner side of the groove at the bottom of the mold, and a filter plate is fixedly connected to the side of the partition close to the bottom plate, and the side of the filter plate away from the partition is flush with the top of the bottom plate. The partition divides the groove at the bottom of the mold into two parts of different sizes, and the larger part is used to accommodate a water pumping component and a filtering component. The cooling water returns to the groove at the bottom of the mold through the second guide pipe, and enters the filtering component after being filtered by the filter plate. The filter plate is arranged to filter larger impurities in the cooling water, such as scale blocks attached to the inner wall of the cooling pipe and washed by cooling water after long-term use. The setting of the filter plate can prevent larger impurities from returning to the cooling pipe and causing blockage. The second guide pipe is directly opposite to the partition, and a section of non-porous partition is arranged instead of a whole porous filter plate. When the cooling water enters the inside of the groove at the bottom of the mold, it can be sprayed onto the surface of the partition and collide with the partition, forming a turbulent water flow in the part without the filtering component, ensuring that the calcium and magnesium ions will not be attached after precipitation, thereby avoiding blockage.

When the pump body is started, the pump body drives the cooling water to flow, and the cooling water passes through the suction pipe, the pump body, the first guide pipe, the cooling pipe, and the second guide pipe in turn, and finally returns to the inside of the groove at the bottom of the mold to achieve circulating cooling. The nozzle of the suction pipe is set upward, and when drawing, the cooling water above is sucked in, which can prevent the sediment at the bottom from being sucked in by the suction pipe.

[0017] Furthermore, a curved plate is slidably connected to one end of the dip tube away from the pump body, and a ring body is fixedly connected to one side of the curved plate close to the dip tube. The surface of the ring body is slidably limited to the end of the dip tube away from the pump body. A plurality of curved plates are provided, and the plurality of curved plates are evenly distributed along the circumference of the ring body. The gaps between the plurality of curved plates can filter the cooling water, and the cooling water enters the dip tube through the gaps between the curved plates, which can speed up the flow rate of the cooling water entering the dip tube, thereby preventing calcium and magnesium ions in the cooling water after cooling from precipitating and adhering to the pipe mouth of the dip tube, avoiding blockage, and maintaining the suction effect.

[0018] Furthermore, a tongue plate is fixedly connected to the inner side surface of the curved plate, and a plurality of tongue plates are arranged along the circumference of the suction tube. A bent plate is fixedly connected to the side of the tongue plate away from the curved plate.

In addition, the arrangement of the tongue plate can further increase the stirring area and improve the disturbance effect on the water flow.

[0019] Furthermore, a stirring plate is fixedly connected to a side of the bent plate away from the tongue plate, and the stirring plate extends to the interior of the suction tube.

The stirring plate can further improve the disturbance effect on the water inlet end of the suction tube to avoid the adhesion of scale. The support frame is provided to limit the rotation of the rotating shaft, making its rotation more stable, thereby ensuring the stable rotation of the ring body and avoiding shaking and wear of the ring body during rotation.

[0020] Furthermore, the filter assembly includes a groove plate, which is fixedly connected to the top of the base plate by bolts, and the side of the groove plate away from the base plate is rigidly clamped with the top of the groove at the bottom of the mold, and the inner side of the groove plate is fixedly connected with a baffle, and the baffles are provided in two groups, the two groups of baffles are arranged in opposite directions, and the two groups of baffles are arranged at intervals with each other, and there are several baffles.

[0021] Furthermore, filter grooves are provided on both sides of several of the baffles, and the filter grooves are arranged in a frame shape, and several filter grooves are evenly distributed on both sides of the baffles. When replacing cooling water, first unscrew the bolts between the outer shell and the bottom plate, remove the outer shell, mold, cooling pipe, first guide pipe, second guide pipe, and water pumping assembly, then drain the cooling water, start the pump body, discharge the cooling water inside the pipeline, then unscrew the bolts between the groove plate and the bottom plate, remove the groove plate and the baffle for cleaning. When assembling, invert the outer shell, mold, cooling pipe, first guide pipe, second guide pipe, and water pumping assembly, then install the groove plate on the top of the bottom plate, and finally install the bottom plate and the groove plate to the bottom of the outer shell. The setting of the filter groove can increase the surface roughness of the baffle, so that scale can adhere to the surface of the baffle more smoothly, thereby enhancing the removal effect of scale entering the next cycle, and the filter groove arranged in a frame shape does not have too many bends and corners. When cleaning, only horizontal and vertical scrubbing is required to remove most of the scale, which is convenient for cleaning.

The surface of the water-drawing component 35 is fixedly connected to the top of the groove at the bottom of the mold 2. The filter component 36 is fixedly connected to the top of the bottom plate 1 by bolts, and the filter component 36 is arranged inside the groove at the bottom of the mold 2. The water-drawing component 35 is started, and the water-drawing component 35 draws cooling water from the groove at the bottom of the mold 2. The cooling water enters the cooling pipe 32 to cool the surrounding of the mold 2. The cooling water temperature rises and finally returns to the groove at the bottom of the mold 2. Then, it is filtered by the filter component 36 and drawn by the water-drawing component 35 again to achieve circulating cooling. The cooling water inside the cooling pipe 32 always flows. The spiral cooling tube 32 can increase the circulation area of ​​cooling water in a limited space and enhance the cooling effect. The spiral integrated structure of the cooling tube 32 has a smooth inner wall without steps compared to the pipeline formed by connecting multiple pipes, which can effectively reduce the adhesion of scale. After the cooling water is heated, the solubility of calcium and magnesium ions therein is reduced, and they are precipitated inside the groove at the bottom of the mold 2 and adsorbed by the filter component 36, thereby reducing the content of calcium and magnesium ions circulating into the cooling tube 32, avoiding the formation of scale on the inner wall of the cooling tube 32, avoiding the blockage of the cooling tube 32, and ensuring that the inner diameter of the cooling tube 32 will not be reduced due to the adhesion of scale, thereby maintaining the cooling effect for a long time.

[0046] The two ends of the cooling pipe 32 are respectively fixedly connected with the first guide pipe 33 and the second guide pipe 34, and the end surface of the first guide pipe 33 is fixedly connected to the end of the cooling pipe 32 away from the bottom plate 1, and the end surface of the second guide pipe 34 is fixedly connected to the end of the cooling pipe 32 close to the bottom plate 1.

The filter plate 38 is set to filter larger impurities in the cooling water. Filter, such as scale blocks attached to the inner wall of the cooling pipe 32 washed by cooling water for a long time, the setting of the filter plate 38 can prevent larger impurities from returning to the cooling pipe 32 and causing blockage. The second guide pipe 34 is directly opposite to the partition 37. A section of non-porous partition 37 is set instead of a whole porous filter plate 38. When the cooling water enters the bottom groove of the mold 2, it can be sprayed onto the surface of the partition 37 and collide with the partition 37, forming a turbulent water flow in the part without the filter component 36, ensuring that the calcium and magnesium ions will not be attached after precipitation, avoiding blockage.

[0048] A filter hole 39 is provided on the surface of the filter plate 38. The filter hole 39 is arranged in a narrow and long ellipse shape. There are a plurality of filter holes 39, which are evenly distributed on the surface of the filter plate 38.

[0051] A tongue plate 356 is fixedly connected to the inner side surface of the curved plate 354. Several tongue plates 356 are arranged along the circumference of the suction tube 352. A bent plate 357 is fixedly connected to the side of the tongue plate 356 away from the curved plate 354. When cooling water passes through the gap of the curved plate 354, the high-speed water flow contacts the bent plate 357, driving the bent plate 357 to move, thereby driving the tongue plate 356 to move, driving the curved plate 354 and the ring body 355 to rotate, thereby stirring the cooling water outside the end of the suction tube 352 to avoid the adhesion of scale. The arrangement of the tongue plate 356 can further increase the stirring area and improve the disturbance effect on the water flow.

[0052] A stirring plate 358 is fixedly connected to the side of the bent plate 357 away from the tongue plate 356, and the stirring plate 358 extends to the inside of the suction tube 352. A rotating shaft 359 is fixedly connected to the side of the stirring plate 358 away from the bent plate 357. The surface of the rotating shaft 359 is rotatably connected to a support frame 3510.

When the baffles 362 are set, the cooling water flows along the inclined direction of the baffles 362 when flowing. Several staggered baffles 362 allow the cooling water to flow along a zigzag waterway, which can fully mix the upper cooling water and the lower cooling water, accelerate the cooling of the cooling water after heating, and ensure that the calcium and magnesium ions in the cooling water can be quickly precipitated at the bottom of the groove plate 361, thereby filtering out scale in the cooling water and preventing the precipitated calcium and magnesium ions from entering the next cycle.

When assembling, the shell 31 is reversed. 1. Mold 2, cooling pipe 32, first guide pipe 33, second guide pipe 34, water-drawing assembly 35, then install the groove plate 361 on the top of the bottom plate 1, and finally install the bottom plate 1 and the groove plate 361 to the bottom of the shell 31. The setting of the filter tank 363 can increase the surface roughness of the baffle plate 362, so that the scale can be more smoothly attached to the surface of the baffle plate 362, thereby enhancing the removal effect of the scale entering the next cycle, and the frame-shaped filter tank 363 does not have too many bends and corners. When cleaning, only horizontal and vertical scrubbing is required to remove most of the scale, which is convenient for cleaning.

[0055] When in use, the pump body 351 is started, and the pump body 351 drives the cooling water to flow. The cooling water passes through the suction tube 352, the pump body 351, the first guide tube 33, the cooling tube 32, and the second guide tube 34 in sequence, and finally returns to the bottom groove of the mold 2 to achieve circulating cooling. The cooling water returns to the bottom groove of the mold 2 through the second guide tube 34, and enters the filter assembly 36 after being filtered by the filter plate 38. When the cooling water flows, it flows along the inclined direction of the baffle plate 362. A plurality of staggered baffle plates 362 make the cooling water flow along the baffle plate 362. The linear water channel flows, and scale adheres smoothly to the surface of the baffle 362. The cooling water passes through the gap of the curved plate 354, and the high-speed water flow contacts the curved plate 357, driving the curved plate 357 to move, thereby driving the tongue plate 356 to move, driving the curved plate 354 and the ring body 355 to rotate, and the curved plate 357 rotates, driving the stirring plate 358 to rotate, and driving the rotating shaft 359 to rotate, disturbing the water inlet end of the suction tube 352 to avoid the adhesion of scale. Then the cooling water enters the cooling tube again through the first guide tube 33 to achieve circulating cooling.
