Description

Technical Field

[0001] This invention relates to the field of mold technology for producing automotive parts with cooling structures, specifically to a mold for producing automotive parts with cooling structures and a cooling method. Background Technology

[0002] A mold is a set of molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects; this tool is composed of various parts, and different molds are composed of different parts. It primarily achieves the shaping of objects by changing the physical state of the material being molded.

[0003] The most important component of existing automotive molds is the body panel mold. These molds are mainly cold stamping dies. In a broad sense, "automotive molds" is a general term for molds used to manufacture all parts of an automobile. The processing of molds is generally carried out in the form of stamping. Stamping is a pressure processing method in which pressure is applied to the material at room temperature using a mold mounted on a press, causing it to separate or plastically deform, thereby obtaining the desired part.

[0004] However, in actual use, the above-mentioned equipment will cause the temperature of the mold to rise rapidly due to the violent extrusion between the upper and lower molds, which will make the mold prone to deformation, severely shorten its service life and affect the quality stability of the product parts. In view of this, we propose a mold for the production of automotive parts with a cooling structure and a cooling method. Summary of the Invention

[0018] A method for cooling a mold used in the production of automotive parts with a cooling structure includes the following steps:

[0019] S1. Start the water tank, so that the coolant in the water tank can be cooled by the inlet pipe, threaded cooling pipe and drain pipe.

[0020] S2. Start the refrigeration unit and introduce refrigerant gas into the base;

[0021] S3. Start the motor to enable the fan to work with the spoiler to accelerate the output of cooling gas inside the base;

[0022] S4. The cold air inside the base flows into the area around the fixed mold through the vent plate;

[0023] S5. Start the cylinder to generate the part through the cooperation of the moving mold and the fixed mold;

[0024] S6. By using the pressure ring and the lower mold frame, the pressure environment around the fixed mold is changed during the processing of the fixed mold;

[0025] S7. During the process of the moving mold and the fixed mold working together, the temperature environment around the fixed mold is compensated by changing the state of the pressure port.

[0026] Compared with the prior art, the present invention provides a mold and cooling method for producing automotive parts with a cooling structure, which has the following beneficial effects:

[0027] 1. The mold for producing automotive parts with a cooling structure and its cooling method involve starting a cylinder, causing the cylinder output end to move downwards, which in turn moves the mounting plate downwards. The downward movement of the mounting plate moves the moving mold downwards, which, in conjunction with the fixed mold, generates the part. During the downward movement of the moving mold, the water tank is activated, and the coolant in the water tank enters the spiral cooling pipe through the inlet pipe. The temperature is transferred between the spiral cooling pipe and the outer wall of the fixed mold, thereby cooling the fixed mold and improving its cooling effect. At the same time, the coolant, after completing the temperature transfer, flows back to the water tank through the drain pipe, completing the recycling of the coolant in the water tank and improving the resource recycling rate of the coolant in the water tank, thus promoting the cooling effect of the processing mold.

[0028] 2. The automotive parts production mold with a cooling structure and its cooling method, in order to improve the cooling effect of the mold, involves starting the motor, the refrigeration unit, and the fan. The refrigeration unit converts outside air into refrigerated gas through the air inlet pipe and inputs it into the base. The movement of the moving block drives the fan to move, realizing the reciprocating motion of the fan in the horizontal direction. The reciprocating motion of the fan in the horizontal direction increases the air blowing area of ​​the fan and increases the air flow rate in the base, causing the refrigerated gas in the base to be quickly sprayed out from the vent plate and act on the area around the fixed mold, creating a cooling environment around the fixed mold. This prevents the fixed mold from rapidly dissipating cold air due to excessive temperature differences with the environment, thus promoting the cooling effect on the processing mold.

[0029] 3. The automotive parts production mold with a cooling structure and the cooling method thereof, wherein the reciprocating lead screw rotates and drives the rotating column to rotate through the pulley, the rotating column rotates and drives the spoiler to rotate, the rotating spoiler cuts the air generated by the fan, thereby converting the upward airflow generated inside the base into a disordered upward airflow, thereby making the cooling effect of the cooling gas on the mold more uniform, and further promoting the cooling effect on the processing mold.

[0030] 4. The automotive parts production mold and cooling method with a cooling structure, during the downward movement of the moving mold, firstly, the air is sealed by the pressure ring and the lower mold frame. Secondly, as the moving mold continues to move downward, the air wrapped in the pressure ring is rapidly compressed, increasing the air pressure in the lower mold frame. The compressed air passes through the pressure port, causing the side door to detach from the magnetic block 2 under the action of the rotating shaft, thus opening the side door. The compressed pressurized gas quickly carries away the high heat during metal stretching through the opening of the side door, improving the cooling effect on the processing mold.

[0031] 5. The mold for producing automotive parts with a cooling structure and the cooling method: After the compressed gas in the lower mold frame is discharged, the side door is closed again by magnetic block one and magnetic block two. When the moving mold impacts into place, the moving mold moves upward, and a negative pressure is generated in the pressure ring. The negative pressure value in the negative pressure environment increases, causing the side door to open again, allowing cold air outside the fixed mold to quickly enter the mold. Combined with the cooling gas generated by the base through the vent plate, the mold is cooled, which further promotes the cooling effect on the processing mold.

[0032] 6. The mold for producing automotive parts with a cooling structure and the cooling method wherein the cooling airflow generated by the base acts on the drain pipe after the coolant has finished circulating, so that the coolant in the drain pipe is rapidly cooled down, the temperature difference of the coolant circulating to the water tank is reduced, the loss of the water tank in the process of changing the coolant temperature is reduced, and the heat exchange efficiency of the water tank for the coolant is improved.

[0041] like Figures 1-7 As shown, the present invention provides a technical solution: a mold for producing automotive parts with a cooling structure and a cooling method, comprising a base 1, a workbench 2 fixedly connected to the upper surface of the base 1, a vent plate 21 fixedly connected to the axial center of the upper surface of the workbench 2, an isolation plate 3 fixedly connected to the outer side of the upper surface of the workbench 2 near the vent plate 21, a lower mold frame 9 fixedly connected to the inner side of the upper surface of the workbench 2 near the isolation plate 3, a fixed mold 10 disposed at the axial center of the upper surface of the vent plate 21, and a parts production device disposed on the upper surface of the workbench 2. The parts production device includes a support column 4 fixedly connected to the right side of the upper surface of the workbench 2 near the isolation plate 3, and the top of the support column 4... A top plate 5 is fixedly connected. A cylinder 6 is installed at the center of the upper surface of the top plate 5. The output shaft of the cylinder 6 is fixedly connected to one end of the clamping rod 61. The other end of the clamping rod 61 is fixedly connected to the mounting plate 7. An auxiliary rod 51 is installed on the right side of the lower surface of the top plate 5 near the clamping rod 61. A moving mold 62 is installed at the center of the lower surface of the mounting plate 7. A pressure ring 63 is movably connected to the outer wall of the moving mold 62. A water tank 8 is fixedly connected to the right end of the upper surface of the workbench 2 near the support column 4. One end of the water inlet pipe 81 is fixedly connected to the output end of the water tank 8. The other end of the water inlet pipe 81 is fixedly connected to one end of the spiral cooling pipe 82. The other end of the spiral cooling pipe 82 is fixedly connected to the drain pipe 83.

[0042] In one embodiment of the present invention, the cylinder 6 is activated, causing the output end of the cylinder 6 to move downward, thereby driving the mounting plate 7 to move downward. The upper surface of the mounting plate 7 begins to have a strip groove, and the cross-sectional area of ​​the strip groove is adapted to the cross-sectional area of ​​the support column 4. The support column 4 passes through and connects to the strip groove. The downward movement of the mounting plate 7 drives the moving mold 62 to move downward. The downward movement of the moving mold 62 cooperates with the fixed mold 10 to realize the generation of the part. The central axis of the top plate 5 in the horizontal direction coincides with the central axis of the base 1 in the horizontal direction and the central axis of the worktable 2 in the horizontal direction. The stability of the workbench 2 is improved. During the downward movement of the moving mold 62, the water tank 8 is activated. The coolant in the water tank 8 enters the spiral cooling pipe 82 through the water inlet pipe 81. The temperature of the fixed mold 10 is transferred through the spiral cooling pipe 82 to the outer wall of the fixed mold 10, thereby cooling the fixed mold 10 and improving the cooling effect of the fixed mold 10. At the same time, the coolant after the temperature transfer is completed flows back to the water tank 8 through the drain pipe 83, completing the recycling of the coolant in the water tank 8 and improving the resource recycling rate of the coolant in the water tank 8, thereby promoting the cooling effect of the processing mold.

[0043] In addition, to improve the cooling effect of the mold, a motor 11 is provided on the right surface of the base 1. The output shaft of the motor 11 is fixedly connected to a reciprocating lead screw 111. A moving block 112 is threadedly connected to the outer wall of the reciprocating lead screw 111. A fan 113 is provided on the upper surface of the moving block 112. One end of a pulley 114 is movably connected to the right end of the outer wall of the reciprocating lead screw 111 near the inner wall of the base 1. The other end of the pulley 114 is movably connected to a rotating column 115. A baffle 116 is fixedly connected to the left end of the rotating column 115. A chiller 12 is provided on the back of the base 1. An air inlet pipe 121 is fixedly connected to the input end of the chiller 12. Starting the motor 11 starts the chiller. 12. Start the fan 113. The refrigerator 12 converts outside air into refrigerant gas through the air inlet pipe 121 and inputs it into the base 1. The output shaft of the motor 11 rotates, driving the reciprocating screw 111 to rotate. The vertical axis of the reciprocating screw 111 coincides with the vertical axis of the moving block 112, improving the stability of the moving block 112. The rotation of the reciprocating screw 111 drives the moving block 112 to perform reciprocating motion in the horizontal direction. The movement of the moving block 112 drives the fan 113 to move, realizing the horizontal reciprocating motion of the fan 113. The horizontal reciprocating motion of the fan 113 increases the... The increased airflow area of ​​fan 113 improves the airflow rate in base 1, allowing the cooling gas in base 1 to be rapidly ejected from the vent plate 21 and applied to the area around the fixed mold 10. This creates a cooling environment around the fixed mold 10, preventing the rapid dissipation of cool air due to large temperature differences in the environment, thus promoting the cooling effect on the processing mold. Furthermore, the rotation of the reciprocating screw 111, via the pulley 114, drives the rotating column 115 to rotate. The rotation of the rotating column 115 drives the baffle 116 to rotate. The horizontal central axis of base 1 coincides with the horizontal central axis of baffle 116, improving the cooling effect of the base 1. The stability of base 1 is improved by the rotation of the baffle 116, which cuts the air generated by the fan 113, thereby converting the upward airflow generated inside base 1 into a disordered upward airflow. This makes the cooling effect of the cooling gas on the mold more uniform, further promoting the cooling effect on the processing mold. At the same time, the cooling airflow generated by base 1 acts on the drain pipe 83 after the coolant has finished circulating, so that the coolant in the drain pipe 83 is rapidly cooled down. This reduces the temperature difference of the coolant circulating to the water tank 8, reduces the loss of the water tank 8 in converting the coolant temperature, and improves the heat exchange efficiency of the water tank 8 for the coolant in the future.

[0044] In an embodiment of the present invention, a pressure-regulating port 91 is fixedly connected to the front surface of the isolation plate 3, a rotating shaft 92 is rotatably connected to the right surface of the pressure-regulating port 91, a side door 93 is fixedly connected to the outer wall of the rotating shaft 92, a magnetic block 94 is fixedly connected to the bottom of the side door 93, and a magnetic block 95 is fixedly connected to the bottom of the inner wall of the pressure-regulating port 91. During the downward movement of the moving mold 62, the cross-sectional area of ​​the outer wall of the pressure ring 63 matches the cross-sectional area of ​​the inner wall of the lower mold frame 9. First, the pressure ring 63, in conjunction with the lower mold frame 9, seals the air. Second, as the moving mold 62 continues to move downward, the air enclosed in the pressure ring 63 is rapidly compressed, increasing the air pressure inside the lower mold frame 9. This causes the compressed air to pass through the pressure-regulating port 91, allowing the side door 93 to pass through the rotating shaft 92. Under the action of the magnetic block 95, the side door 93 is opened, allowing the compressed pressurized gas to quickly remove the high heat from the metal during stretching, thus improving the cooling effect on the processing mold. After the compressed gas is discharged, the magnetic properties of the magnetic block 94 are opposite to those of the magnetic block 95. The magnetic block 94, in conjunction with the magnetic block 95, closes the side door 93 again. When the moving mold 62 impacts into place, it moves upward, generating a negative pressure inside the pressure ring 63. The negative pressure value in the negative pressure environment increases, causing the side door 93 to open again, allowing the cold air outside the fixed mold 10 to quickly enter the mold. Combined with the cooling gas generated by the vent plate 21 through the base 1, the mold is cooled, further promoting the cooling effect on the processing mold.

[0045] In this invention, during use, cylinder 6 is activated, causing its output end to move downwards, which in turn moves mounting plate 7 downwards. The downward movement of mounting plate 7 then moves moving mold 62 downwards. The downward movement of moving mold 62, in conjunction with fixed mold 10, generates the part. During the downward movement of moving mold 62, water tank 8 is activated. Coolant in water tank 8 enters spiral cooling pipe 82 through inlet pipe 81. Temperature transfer between spiral cooling pipe 82 and the outer wall of fixed mold 10 completes the cooling of fixed mold 10. After temperature transfer, the coolant flows back to water tank 8 through drain pipe 83, completing the recycling of coolant in water tank 8. Motor 11 is activated, refrigerator 12 is activated, and fan 113 is activated. Refrigeration unit 12 cools the part through air inlet pipe 121. Outside air is converted into cooling gas and input into the base 1. The output shaft of the motor 11 rotates, driving the reciprocating screw 111 to rotate. The rotation of the reciprocating screw 111 drives the moving block 112 to reciprocate horizontally. The movement of the moving block 112 drives the fan 113 to move, realizing the horizontal reciprocating motion of the fan 113. The horizontal reciprocating motion of the fan 113 increases the air blowing area of ​​the fan 113, causing the cooling gas in the base 1 to be quickly ejected from the vent plate 21 and act on the area around the fixed mold 10, creating a cooling environment around the fixed mold 10. This prevents the fixed mold 10 from rapidly dissipating cool air due to excessive temperature differences with the environment, thus promoting the cooling effect on the processing mold. The rotation of the reciprocating screw 111 is transmitted through the pulley 114. The rotating column 115 rotates, which in turn rotates the baffle 116. The baffle 116 cuts the air generated by the fan 113, thus converting the upward airflow generated inside the base 1 into a disordered upward airflow. This makes the cooling effect of the cooling gas on the mold more uniform. The cooling airflow generated by the base 1 acts on the drain pipe 83 after the coolant has finished circulating, which rapidly cools the coolant in the drain pipe 83. This reduces the temperature difference between the coolant circulating to the water tank 8 and reduces the loss of coolant temperature in the water tank 8. As the moving mold 62 moves downward, the pressure ring 63 first seals the air with the lower mold frame 9. Then, as the moving mold 62 continues to move downward, the pressure ring 63 wraps around the mold frame 9. The air is rapidly compressed, increasing the air pressure inside the lower mold frame 9. The compressed air passes through the pressure port 91, causing the side door 93 to open under the action of the rotating shaft 92, disengaging from the magnetic block 2 95. The compressed pressurized gas quickly carries away the high heat during metal stretching through the opening of the side door 93, improving the cooling effect on the processing mold. After the compressed gas is discharged, the side door 93 is closed again by the cooperation of the magnetic block 1 94 and the magnetic block 2 95. When the moving mold 62 impacts into place, the moving mold 62 moves upward, generating a negative pressure inside the pressure ring 63. The negative pressure value in the negative pressure environment increases, causing the side door 93 to open again, allowing the cold air outside the fixed mold 10 to quickly enter the mold. This, combined with the cooling gas generated by the base 1 through the vent plate 21, cools the mold.

[0046] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
