DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 7 As shown, an automobile parts rapid cooling mold according to an embodiment of the present invention comprises a workbench 1, a lower mold base 11 is arranged at the top of the workbench 1, and an upper mold base 12 is arranged at the top of the lower mold base 11; a cooling through hole 13 is opened on the side of the lower mold base 11, and a water inlet pipe 14 is arranged at the water inlet end of the cooling through hole 13;

[0034] A rectangular hole 15 connected to the cooling through hole 13 is provided on the side of the lower die base 11, and a detection plate 2 is slidably connected inside the rectangular hole 15. A guide rod 21 is provided on the side of the detection plate 2 away from the cooling through hole 13, and an air plate 22 is provided on the end of the guide rod 21 away from the detection plate 2. An air cylinder 23 is provided on the outer side of the air plate 22, and the air plate 22 is slidably connected inside the air cylinder 23; a pressure relief valve 24 is provided at the air outlet end of the air cylinder 23;

[0035] When cooling the mold, due to the extremely high temperature of the mold when in use, when the cooling water enters the cooling cavity of the mold, the cooling water will be evaporated instantly, generating a large amount of water vapor, resulting in an instantaneous high pressure in the cooling cavity; the high pressure can easily cause the mold to be cracked by impact; to solve the above problems, the embodiment of the present invention is provided with a detection plate 2, an air cylinder 23 and other structures; the specific use process is as follows; when cooling the mold, the staff injects external cooling water into the cooling through hole 13 in the lower mold base 11 through the water inlet pipe 14, and the cooling water flows in the cooling through hole 13 and is discharged to cool the mold; in this process, the cooling water evaporates rapidly in the cooling through hole 13, and due to the extremely high temperature of the mold, a large amount of water vapor will be generated instantly, resulting in a rapid increase in the pressure in the cooling through hole 13, and the pressure effect To the side of the detection plate 2 inside the rectangular hole 15, the detection plate 2 drives the guide rod 21 to move inside the air cylinder 23. When the gas in the air cylinder 23 is compressed to a certain extent, it is discharged through the pressure relief valve 24. The detection plate 2 further moves in the rectangular hole 15, so that the pressure relief space of the cooling through hole 13 is increased, and the instantaneous pressure in the cooling through hole 13 is prevented from being excessive, causing the mold to crack and damage; it should be pointed out that high-boiling point coolant can be used to further alleviate the above-mentioned problem, but it still cannot be avoided, because the boiling point of high-quality high-boiling point coolant is 100℃-200℃; and the temperature of the mold during the metal pouring process can reach above 500℃; therefore, the technical solution of the present invention is practical; in addition, the price of high-boiling point coolant is relatively expensive, so large-scale use will increase the cost, so general coolant can be used in the technical solution of the present invention.

[0036] An air pump 25 is provided at the top of the workbench 1 and on one side of the lower mold base 11. The output end of the air pump 25 is connected to the air cylinder 23 and an inflation tube 26 is provided. When in use, the air pump 25 is started to continuously inflate the air cylinder 23 through the inflation tube 26 to ensure that the detection plate 2 is reset to the initial position after the mold is cooled, so as to facilitate continued use thereafter.

[0037] A pair of connecting rods 3 are arranged on the side of the guide rod 21 outside the rectangular hole 15. A blocking plate 42 is arranged on the end of the connecting rod 3 away from the guide rod 21. A water outlet pipe 41 is arranged on the outside of the blocking plate 42. Initially, the blocking plate 42 blocks the water outlet pipe 41. The top of the water outlet pipe 41 is connected to a water tank 4, and the water tank 4 stores heated liquid water. The side of the water outlet pipe 41 is connected to a water outlet assembly. The water outlet assembly penetrates into the interior of the cooling through hole 13. When the guide rod 21 moves, The guide rod 21 drives the sealing plate 42 to move through the connecting rod 3, so that the blocked part of the water outlet pipe 41 is unblocked, and the water outlet pipe 41 discharges the liquid water in the water tank 4 into the cooling through hole 13 through the water outlet assembly. Since the water tank 4 stores heated liquid water, the cooling water entering the cooling through hole 13 is heated, and the cooling water temperature increases, which reduces the heat absorption capacity, thereby reducing the generation of water vapor, further reducing the pressure inside the cooling through hole 13, and protecting the mold.

[0038] The water outlet assembly includes a water storage head 43 and a through pipe 44. The water storage head 43 is connected to the water outlet pipe 41 and is located below the sealing plate 42. The water outlet pipe 41 is provided with multiple ends and one end is connected to the water storage head 43, and the other end passes through the interior of the cooling through hole 13. The liquid water entering the cooling through hole 13 is sprayed to different positions through the water outlet pipe 41, so that the liquid water in the water tank 4 is evenly mixed with the liquid water in the cooling through hole 13, which is beneficial to improve the protection effect of the mold.

[0039] A rotating shaft 5 is inserted through the side of the lower mold base 11, and the rotating shaft 5 passes through the interior of the cooling through hole 13; a plurality of inclined baffles 51 are provided on the axial surface of the rotating shaft 5, and a plurality of stirring blocks 52 are provided on the axial surface of the rotating shaft 5 and on both sides of the inclined baffles 51; when in use, cooling water flows in the cooling through hole 13, and the generated steam flow acts on the inclined baffles 51 on the rotating shaft 5, so that the inclined baffles 51 drive the rotating shaft 5 to rotate, and the rotating shaft 5 drives the stirring blocks 52 to rotate in the cooling through hole 13, and the liquid water entering the cooling through hole 13 is further stirred and mixed, thereby further making the liquid water in the water tank 4 evenly mixed with the liquid water in the cooling through hole 13.

[0040] A heating block 62 is inserted through the top of the water tank 4, and the side of the heating block 62 is slidably connected to the side of the lower mold base 11; a hydraulic cylinder 6 is provided on the side of the heating block 62 away from the lower mold base 11, and the hydraulic cylinder 6 is installed on the top of the workbench 1; a connecting frame 61 is provided between the output end of the hydraulic cylinder 6 and the heating block 62; when the mold is in use, the temperature of the mold surface will rise rapidly; the heating block 62 attached to the side of the lower mold base 11 is heated, and at this time the hydraulic cylinder 6 is controlled to start, and the hydraulic cylinder 6 drives the heating block 62 to move downward through the connecting frame 61, so that the bottom end of the heating block 62 is inserted into the liquid water in the water tank 4, and the liquid water is heated, so that the liquid water in the water tank 4 continues to maintain a high temperature, which is convenient to use.

[0041] like Figures 7 to 10 As shown, a temperature sensor 40 is installed on the side of the water tank 4. The temperature sensor 40 is used to monitor the temperature of the liquid water in the water tank 4, and the temperature sensor 40 is connected to the external early warning device through an electrical signal; the temperature sensor 40 monitors the temperature of the liquid water in the water tank 4 in real time, so that the staff can control the hydraulic cylinder 6 to drive the heating block 62 to move upward in time when the liquid water in the water tank 4 is overheated, so as to stop the heating of the liquid water and avoid the liquid water in the water tank 4 being overheated and affecting the use effect.

[0042] The temperature sensor 40 is connected to the controller of the hydraulic cylinder 6 through an electrical signal; the temperature sensor 40 monitors the temperature of the liquid water in the water tank 4 in real time, and automatically controls the hydraulic cylinder 6 to drive the heating block 62 to move upward when the liquid water in the water tank 4 is overheated, thereby stopping the heating of the liquid water and improving the automation effect.

[0043] A floating tube 7 is inserted through the top of the water tank 4, and the bottom of the floating tube 7 is inserted into the liquid water inside the water tank 4. A water adding cylinder 71 is arranged at the top of the floating tube 7, and the water adding cylinder 71 is suspended above the floating tube 7 through a support frame; the water adding cylinder 71 is located directly above the floating tube 7 and has a water leakage opening; a rotating plate 72 is arranged inside the water leakage opening, and a rotating shaft 73 is arranged on the side of the rotating plate 72, and the rotating shaft 73 is rotatably connected to the inside of the water leakage opening; initially, the top of the floating tube 7 supports the rotating plate 72 so that the rotating plate 72 remains horizontal to block the water leakage opening; During use, the liquid water in the water tank 4 gradually decreases, and the float tube 7 gradually moves downward. When the float tube 7 moves downward, the rotating plate 72 loses its support and deflects with the action of the rotating shaft 73, so that the leakage port at the bottom of the water adding cylinder 71 opens; then the leakage port adds the internal liquid water into the water tank 4 through the float tube 7. When the liquid water level in the water tank 4 rises, the float tube 7 moves upward synchronously under the action of buoyancy to lift and reset the rotating plate 72, and then the leakage port is blocked again, thereby realizing the process of automatically adding water to the water tank 4 and improving the automation effect of use.

[0044] A flexible diaphragm is provided between the top of the rotating plate 72 and the inner wall of the water adding cylinder 71 , and the flexible diaphragm blocks the gap between the rotating shaft 73 and the water leakage port, thereby preventing liquid water from leaking out through the gap between the rotating shaft 73 and the water leakage port.
