Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for die casting molds, and specifically to a rapid cooling device for die casting molds. Background Technology

[0002] During the die-casting production process, the die-casting mold accumulates a large amount of heat after continuous operation. If it cannot be cooled effectively in time, the mold temperature will become too high. Excessive temperature will not only affect the molding quality of the die-cast products, causing problems such as deformation and substandard dimensional accuracy, but will also shorten the service life of the mold and increase production costs.

[0003] Currently, the common cooling methods for die-casting molds on the market are usually either water cooling or air cooling. In practice, water cooling typically involves opening cooling water channels inside the mold and circulating cooling water for heat exchange. However, this method suffers from slow cooling speed and poor cooling uniformity. Furthermore, when the cooling water channels become blocked, it is difficult to quickly troubleshoot and clean them, affecting the cooling effect. Air cooling, on the other hand, uses a fan to blow air onto the mold surface for cooling. However, its cooling efficiency is low, especially for the core areas inside the mold, where the cooling effect is poor and cannot meet the needs of high-efficiency production. Utility Model Content

[0004] The purpose of this invention is to provide a rapid cooling device for die-casting molds to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a rapid cooling device for die casting molds, including a die casting platform body, a fixed mold body, and a moving mold body. The die casting platform body is arranged horizontally, the fixed mold body is fixed in the middle of the top surface of the die casting platform body, and the moving mold body is pressed against the top of the fixed mold body, so as to form a complete die casting mold structure with the help of the moving mold body and the fixed mold body.

[0007] The moving mold body and the fixed mold body are covered with heat conduction and heat dissipation components, which are used to conduct heat to the outside and dissipate it by means of the heat conduction and heat dissipation components covering the outside.

[0008] The top of the heat-conducting and heat-dissipating component is equipped with a blower cooling component, and the blower cooling component is connected to a cold air supply component, so as to achieve efficient blowing cooling of the heat-conducting and heat-dissipating component and direct blowing cooling of the top of the moving mold body.

[0009] Preferably, the heat conduction and heat dissipation assembly includes a heat conduction cover and heat dissipation fins. The heat conduction cover is a rectangular cover that is open at the top and bottom. The top of the heat conduction cover is equipped with the air blowing heat dissipation assembly. The heat conduction cover covers the outside of the moving mold body and the fixed mold body in a vertically spaced manner. A heat conduction liner is attached and fixed to the inner wall of the heat conduction cover. The heat conduction liner is in close contact with the outside of the moving mold body and the fixed mold body. Multiple heat dissipation fins are evenly distributed and fixed on the outer peripheral end face of the heat conduction cover.

[0010] Preferably, the heat-conducting cover is a metal cover, and the top surface of the heat-conducting cover is higher than the highest point of the top of the moving mold body.

[0011] Preferably, the heat dissipation fins are all vertically arranged rectangular strip fins, and the heat dissipation fins are integrally formed with the heat conduction cover.

[0012] Preferably, the thermally conductive liner is a thermally conductive silicone patch.

[0013] Preferably, the air-blowing heat dissipation assembly includes a cold air distribution box and a distribution pipe. The cold air distribution box is a hollow box in the shape of a rectangular frame, and the cold air distribution box is fixedly and horizontally on the top surface of the heat conduction cover. A cold air inlet pipe is fixedly and horizontally connected to the outer side of the cold air distribution box, and the cold air inlet pipe is connected to the cold air supply assembly. Air-blowing openings are provided around the bottom surface of the cold air distribution box, and the air-blowing openings are aligned vertically with the heat dissipation fins on the corresponding sides. Multiple horizontally placed cold air distribution pipes are fixedly connected between the two sides of the inner periphery of the cold air distribution box. Air-blowing holes are evenly distributed on the bottom periphery of the cold air distribution pipes, and the air-blowing holes are suspended above the top of the moving mold body.

[0014] Preferably, all the air blowing openings are rectangular openings, and all the air blowing holes are circular holes with their axes arranged vertically.

[0015] Preferably, the top surface of the cold air distribution box is fixedly installed with inverted U-shaped handles on both sides, and the horizontal part of the handles is coaxially fitted with a buffer sleeve.

[0016] Preferably, the cold air supply assembly includes an industrial air cooler body and a cold air delivery pipe. A cold air exhaust pipe for discharging supplied cold air is provided on one side of the industrial air cooler body, and the cold air exhaust pipe and the cold air inlet pipe are connected together through the cold air delivery pipe.

[0017] Preferably, the outer ends of the cold air exhaust pipe and the cold air inlet pipe, as well as both ends of the cold air conveying pipe, are all fixedly equipped with pipe flanges, and the cold air conveying pipe is connected to the cold air exhaust pipe and the cold air inlet pipe by means of bolts after the pipe flanges are aligned.

[0018] In practical application, the aforementioned rapid cooling device for die-casting molds, due to the inclusion of the heat-conducting and heat-dissipating components, allows heat to be conducted to the heat dissipation fins for dissipation after the moving mold body and the fixed mold body are closed. The heat-conducting cover of the heat-conducting and heat-dissipating components covers the moving mold body and the fixed mold body from top to bottom, and the heat-conducting liner is in close contact with the exterior of the moving mold body and the fixed mold body. This allows heat to be conducted to the heat dissipation fins for dissipation by increasing the heat dissipation area through the heat dissipation fins. The cooling efficiency of the moving mold body and the fixed mold body is improved by the fact that the top of the heat dissipation assembly is equipped with the air blowing assembly, which is connected to the cold air supply assembly. Furthermore, by utilizing the air blowing openings on all four sides of the bottom surface of the cold air distribution box, which are aligned vertically with the corresponding heat dissipation fins, cold air can be blown from top to bottom through the air blowing openings and flow stably along the gaps between the heat dissipation fins. This achieves efficient air blowing and cooling of the heat dissipation fins, improving the cooling efficiency of the moving mold body. The cooling efficiency of the moving mold body and the fixed mold body is improved by blowing air from top to bottom onto the top of the moving mold body through the air holes at the bottom of the cold air distribution pipe between the inner walls of the cold air distribution box. This achieves efficient airflow cooling of the moving mold body directly, further improving the cooling efficiency of both the moving mold body and the fixed mold body. Furthermore, after cooling the moving mold body and the fixed mold body, simply raising the heat-conducting cover of the heat-dissipating component from bottom to top until it is higher than the moving mold body allows the heat-conducting component and the fixed mold body to be cooled. The heat dissipation and cooling components are detached from the exterior of the moving mold body and the fixed mold body. The combination and separation of the heat dissipation and cooling components outside the moving mold body and the fixed mold body is simple and easy to implement. This facilitates the heat dissipation and cooling of the moving mold body and the fixed mold body after they are combined outside the moving mold body and the fixed mold body. It also facilitates the timely separation of the heat dissipation and cooling components after the heat dissipation and cooling are completed so that the moving mold body and the fixed mold body can be opened smoothly.

[0019] The beneficial effects are as follows: 1. This utility model is equipped with a heat conduction and heat dissipation component. After the moving mold body and the fixed mold body are closed, the heat conduction cover of the heat conduction and heat dissipation component covers the outside of the moving mold body and the fixed mold body from top to bottom. The heat conduction inner liner is in close contact with the outside of the moving mold body and the fixed mold body. The heat can be conducted to the heat dissipation fins by means of the heat conduction inner liner and the heat conduction cover. This realizes the improvement of the cooling efficiency of the moving mold body and the fixed mold body by increasing the heat dissipation area through the heat dissipation fins.

[0020] 2. The top of the heat conduction and heat dissipation assembly is equipped with a blower heat dissipation assembly, which is connected to the cold air supply assembly. By opening blower openings around the bottom of the cold air distribution box and aligning them with the corresponding heat dissipation fins, cold air can be blown from top to bottom through the blower openings and flow stably along the gaps between the heat dissipation fins. This achieves efficient cooling of the heat dissipation fins and improves the cooling efficiency of the heat conduction and heat dissipation assembly for the moving mold body and the fixed mold body. At the same time, by blowing air from top to bottom to the top of the moving mold body through the blower holes at the bottom of the cold air distribution pipe between the inner walls of the cold air distribution box, efficient cooling of the moving mold body can be achieved directly, further improving the cooling efficiency of the moving mold body and the fixed mold body.

[0021] 3. After the moving mold body and the fixed mold body have cooled down, simply raise the heat conduction cover of the heat conduction and heat dissipation component from bottom to top until it is higher than the moving mold body. Then, the heat conduction and heat dissipation component and the air blowing heat dissipation component can be removed from the outside of the moving mold body and the fixed mold body. The combination and separation of the heat conduction and heat dissipation component and the air blowing heat dissipation component outside the moving mold body and the fixed mold body is simple and easy to implement. It is convenient to combine the heat conduction and heat dissipation component and the air blowing heat dissipation component together outside the moving mold body and the fixed mold body for heat dissipation and cooling. At the same time, it is convenient to remove the heat conduction and heat dissipation component and the air blowing heat dissipation component in time after the heat dissipation and cooling is completed so that the moving mold body and the fixed mold body can be opened smoothly.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] See Figures 1-6As shown, this utility model provides a rapid cooling device for die casting molds, including a die casting platform body 2, a fixed mold body 6, and a moving mold body 3. The die casting platform body 2 is arranged horizontally, the fixed mold body 6 is fixed in the middle of the top surface of the die casting platform body 2, and the moving mold body 3 is pressed against the top of the fixed mold body 6, so as to form a complete die casting mold structure with the help of the moving mold body 3 and the fixed mold body 6. The moving mold body 3 and the fixed mold body 6 are covered with a heat-conducting and heat-dissipating component 7. This component 7 is used to conduct heat to the outside for dissipation. Specifically, the heat-conducting and heat-dissipating component 7 includes a heat-conducting cover 702 and heat dissipation fins 701. The heat-conducting cover 702 is a rectangular cover that is open at the top and bottom. A blower heat dissipation component 1 is assembled on the top of the heat-conducting cover 702. The heat-conducting cover 702 covers the moving mold body 3 and the fixed mold body 6 with a vertical clearance fit. A heat-conducting liner 703 is attached and fixed to the inner wall of the heat-conducting cover 702, and the heat-conducting liner 703 is in close contact with the moving mold body 3 and the fixed mold body 6. On the outside, multiple heat dissipation fins 701 are evenly distributed and fixed on the outer periphery of the heat conduction cover 702. The purpose of this arrangement is that after the moving mold body 3 and the fixed mold body 6 are closed, the heat conduction cover 702 of the heat conduction heat dissipation component 7 covers the outside of the moving mold body 3 and the fixed mold body 6 from top to bottom, and the heat conduction inner liner 703 is in contact with the outside of the moving mold body 3 and the fixed mold body 6. The heat can be conducted to the heat dissipation fins 701 for dissipation by means of the heat conduction inner liner 703 and the heat conduction cover 702. This realizes the improvement of the cooling efficiency of the moving mold body 3 and the fixed mold body 6 by increasing the heat dissipation area by the heat dissipation fins 701.

[0033] See Figures 1-6As shown, a blower cooling component 1 is assembled on the top of the heat conduction and heat dissipation component 7, and the blower cooling component 1 is connected to a cold air supply component 5. This allows for efficient blowing cooling of the heat conduction and heat dissipation component 7 and direct blowing cooling of the top of the moving mold body 3. Specifically, the blower cooling component 1 includes a cold air distribution box 102 and a distribution pipe. The cold air distribution box 102 is a hollow box in the shape of a rectangular frame, and it is horizontally fixed to the top surface of the heat conduction cover 702. A horizontal connection is made to the outer side of the cold air distribution box 102. Cold air enters through pipe 101, which is connected to the cold air supply assembly 5. Air outlets 106 are provided around the bottom of the cold air distribution box 102, and these outlets 106 are aligned vertically with the corresponding heat dissipation fins 701. Multiple horizontally arranged cold air distribution pipes 103 are fixedly connected between the inner circumference of the cold air distribution box 102. Air holes 107 are evenly distributed around the bottom periphery of each cold air distribution pipe 103, and these air holes 107 are suspended above the top of the moving mold body 3. The cold air supply assembly 5 includes an industrial air cooler body 501 and... A cold air delivery duct 503 is provided on one side of the industrial air cooler body 501, for discharging supplied cold air. The cold air discharge duct 502 and the cold air inlet duct 101 are connected by the cold air delivery duct 503. This arrangement allows cold air to be blown from top to bottom through the air outlets 106 on all four sides of the bottom surface of the cold air distribution box 102, which are aligned vertically with the corresponding heat dissipation fins 701. The cold air flows stably along the gaps between the heat dissipation fins 701, thereby achieving… The efficient airflow cooling of the heat dissipation fins 701 improves the cooling efficiency of the heat conduction and heat dissipation components 7 for the moving mold body 3 and the fixed mold body 6. At the same time, by using the airflow holes 107 at the bottom of the cold air distribution pipe 103 between the inner walls of the cold air distribution box 102 to blow air from top to bottom to the top of the moving mold body 3, efficient airflow cooling of the moving mold body 3 can be achieved directly, further improving the cooling efficiency of the moving mold body 3 and the fixed mold body 6. Moreover, it is convenient to use the industrial air cooler body 501 to efficiently and stably supply the cold air required for cooling into the cold air distribution box 102.

[0034] See Figures 1-4As shown, the following optimizations have been made to this application: the heat-conducting cover 702 is a metal cover, and the top surface of the heat-conducting cover 702 is higher than the highest point of the top of the moving mold body 3. This configuration firstly facilitates the heat-conducting cover 702 to have stable heat conduction and dissipation capabilities, and also ensures that the heat-conducting cover 702 can completely cover the moving mold body 3 and the fixed mold body 6, and also ensures that the air-blowing heat dissipation assembly 1 does not interfere with the top of the moving mold body 3. Further optionally, the heat dissipation fins 701 are all vertically arranged rectangular strip fins, and the heat dissipation fins 701 are integrally formed with the heat-conducting cover 702, so as to ensure that when the air blowing opening 106 blows downward, the cold air can flow efficiently along the gaps between the heat dissipation fins 701.

[0035] See Figures 1-6 As shown, the thermally conductive liner 703 is a thermally conductive silicone patch, which ensures stable thermal conductivity. Optionally, the air outlets 106 are rectangular openings, and the air holes 107 are vertically oriented circular holes. This design ensures that the air outlets 106 can cover the corresponding heat dissipation fins 701, and that the air holes 107 can stably blow air downwards. Further optionally, inverted U-shaped handles 105 are fixedly installed on both sides of the top surface of the cold air distribution box 102, and the horizontal parts of the handles 105 are coaxially fitted with buffer sleeves 104, facilitating the operator to grip the handles 105 to lift and lower the thermally conductive heat dissipation assembly 7 and the air-blowing heat dissipation assembly 1. Furthermore, pipe flanges 4 are fixedly installed at the outer ends of the cold air exhaust pipe 502 and the cold air inlet pipe 101, as well as at both ends of the cold air delivery pipe 503. The cold air delivery pipe 503 is connected to the cold air exhaust pipe 502 and the cold air inlet pipe 101 by bolts after the pipe flanges 4 are aligned. This method ensures that the cold air delivery pipe 503 is stably connected to the cold air exhaust pipe 502 and the cold air inlet pipe 101. Preferably, a sealing rubber gasket can be added between the pipe flanges 4 to improve the sealing effect.

[0036] With the above structure, in practical use, due to the presence of the heat-conducting and heat-dissipating component 7, after the moving mold body 3 and the fixed mold body 6 are closed, the heat-conducting cover 702 of the heat-conducting and heat-dissipating component 7 covers the outside of the moving mold body 3 and the fixed mold body 6 from top to bottom, and is in contact with the outside of the moving mold body 3 and the fixed mold body 6 by the heat-conducting inner liner 703. The heat can be conducted to the heat dissipation fins 701 for dissipation by the heat-conducting inner liner 703 and the heat-conducting cover 702, thereby increasing the heat dissipation area of ​​the moving mold body by the heat dissipation fins 701. The cooling efficiency of body 3 and fixed mold body 6 is improved by the fact that the top of the heat conduction and heat dissipation component 7 is equipped with a blower heat dissipation component 1, which is connected to the cold air supply component 5. Furthermore, by utilizing the method of opening blower openings 106 around the bottom surface of the cold air distribution box 102, which are aligned vertically with the corresponding heat dissipation fins 701, cold air can be blown from top to bottom through the blower openings 106 and flow stably along the gaps between the heat dissipation fins 701. This achieves efficient cooling of the heat dissipation fins 701, improving the cooling efficiency of the heat conduction and heat dissipation component 7 for moving parts. The cooling efficiency of the mold body 3 and the fixed mold body 6 is improved by using the air blowing holes 107 at the bottom of the cold air distribution pipe 103 between the inner walls of the cold air distribution box 102 to blow air from top to bottom towards the top of the moving mold body 3. This achieves efficient air blowing and cooling of the moving mold body 3 directly, further improving the cooling efficiency of the moving mold body 3 and the fixed mold body 6. After the moving mold body 3 and the fixed mold body 6 have been cooled, it is only necessary to raise the heat conduction cover 702 of the heat conduction and heat dissipation component 7 from bottom to top until it is higher than the moving mold body 3 to dissipate the heat. Component 7 and the heat dissipation component 1 are detached from the outside of the moving mold body 3 and the fixed mold body 6. The combination and separation of the heat dissipation component 7 and the heat dissipation component 1 outside the moving mold body 3 and the fixed mold body 6 is simple and easy to implement. It is convenient to combine the heat dissipation component 7 and the heat dissipation component 1 together outside the moving mold body 3 and the fixed mold body 6 for heat dissipation and cooling. It is also convenient to detach the heat dissipation component 7 and the heat dissipation component 1 together in time after the heat dissipation and cooling is completed so that the moving mold body 3 and the fixed mold body 6 can be opened smoothly.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
