Description

Technical Field

[0001] The invention relates to the technical field of stamping metals, in particular to an automobile parts processing die capable of preventing overheating. Background Art

[0002] Auto parts processing molds are precision tools used to manufacture auto parts. They use stamping technology to process metal sheets or plastic materials into parts that meet design requirements. These molds have high precision, high durability and complex structures, and can achieve large-scale production, ensuring the dimensional accuracy and surface quality of parts, and meeting the automotive industry's strict requirements for part quality and production efficiency.

[0003] However, during long-term and frequent stamping processes, especially during hot stamping processes, the temperature of existing automobile parts processing molds will continue to rise. Overheating will cause the mold to expand and deform, and even cause the rod channel of the mold to shrink, thereby affecting the normal ejection action of the ejector mechanism and possibly causing the rod to get stuck. The current mold cooling methods mainly include air cooling and water cooling. The heat dissipation efficiency of air cooling is low and usually only the heat dissipation of the mold surface can be achieved. Although water cooling has high heat dissipation efficiency, in order to improve the heat dissipation efficiency inside the mold, a refrigerant liquid channel needs to be opened in the mold, which may reduce the strength of the mold. Therefore, based on the above problems, a mold for automobile parts processing that prevents overheating is proposed. Summary of the Invention

[0013] Compared with the prior art, the present application has the following advantages: 1. In the present invention, by providing the base portion, the partitioning guide portion, the heat conducting portion, the ejection portion and the lower mold, the base portion can, on the one hand, carry the partitioning guide portion, the heat conducting portion, the ejection portion and the lower mold, and on the other hand, store the refrigerant liquid. The main frame can drive the ejection portion to move when in motion. The displacement of the ejection portion can, on the one hand, perform the ejection and demoulding operation, and on the other hand, compress the stored refrigerant liquid, so that after the respective bag sleeves of the partitioning guide portion receive the refrigerant liquid, they expand and expand to cool the respective rods. Subsequently, the refrigerant liquid will reset in the next stamping operation and conduct the heat to the heat conducting portion, and be ejected through the gas transmission portion. The airflow dissipates heat from the heat-conducting part. This operation can keep the refrigerant liquid at a low temperature, providing good cooling conditions for the subsequent continuous cooling of the lower mold. The automotive parts processing mold automatically cools itself through dual cooling measures during the stamping process without increasing power consumption or affecting mold strength.

In the present invention, by providing structures such as a partitioning guide part and a lubricating part, the control box can control the operation of the two-way liquid pump at a regular time, draw lubricating oil from the liquid tank through the connecting pipe, and send it to the sleeve through the infusion pipe and the shunt pipe. After the lubricating oil reaches the sleeve, it will be smeared on the outer surface of the bag sleeve contracted by the partitioning guide part. Then the control box controls the two-way liquid pump to run in the reverse direction, draws the lubricating oil back through the through pipe, the shunt pipe and the infusion pipe, and returns it to the liquid tank through the connecting pipe to complete the cycle. This reciprocating process regularly oils the surface of the bag sleeve. During ejection and demoulding, the expansion of the bag sleeve can smear the lubricating oil on the inner wall of the rod channel. This process not only improves the smoothness of the ejection and demoulding operation, but also greatly reduces the rod jamming phenomenon caused by insufficient lubrication, avoids damage to the mold and parts due to rod jamming, thereby extending the service life of the mold, improving production efficiency, and reducing production costs.

The inner sides of the guide holes 62 are fixedly connected with liquid guides 63, and the upper sides of the liquid guides 63 are fixedly connected with bag sleeves 64, and the upper ends of the bag sleeves 64 are located on the inner sides of the connection holes 33. The upper sides of the bag sleeves 64 are fixedly connected with sealing rings 65 located in the rod channel 43. The inner side of the partition plate 61 is provided with a plurality of gate openings 67. Through this arrangement, the partition guide portion 6 can guide the refrigerant liquid flowing out of the lower liquid shell 31. The base portion 3 is installed. There is an ejection part 5, which includes a flow-pushing plate 51 slidably connected to the inner wall of the lower liquid shell 31. The upper left and right sides of the flow-pushing plate 51 are fixedly connected with a connecting rod 52. The upper end of the connecting rod 52 passes through the lower liquid shell 31 and is fixedly connected with a connecting bar 53. The connecting bar 53 is slidably connected to the guide groove 16 on the front and rear sides. The inner side of the middle hole of the liquid guide 63 is slidably connected with a ejector rod 54 whose lower end is fixedly connected to the flow-pushing plate 51, and the upper end of the ejector rod 54 passes through the bag sleeve 64 and the connecting hole 33 is on the inner side of the rod channel 43. The upper end of the ejector rod 54 is fixedly connected with a ejector block 55. Through this arrangement, the ejection part 5 can be ejected on the one hand. The demoulding operation is carried out. On the other hand, the stored refrigerant liquid can be compressed so that the bag sleeves 64 of the separating guide part 6 receive the refrigerant liquid and expand to cool the rod channels 43. A spring 66 is provided between the top block 55 and the sealing ring 65 and is sleeved on the outside of the top rod 54. Through this arrangement, the spring 66 can be used to reset the expanded bag sleeve 64. A pair of heat conducting parts 7 are installed on the inner side of the base part 3; the heat conducting part 7 includes a heat conducting plate 71 fixed on the inner side of the contact port 34, and the upper end surface of the heat conducting plate 71 is in contact with the lower end surface of the mold body 41, and the lower side of the heat conducting plate 71 is fixedly connected with a plurality of equidistant The heat dissipation fins 72 are arranged in an array, and some of the heat dissipation fins 72 are provided with a plurality of vent holes 73 that are arranged through them. The inner side of the grid opening 67 is slidably connected to a heat conducting sheet 74 whose lower end is fixedly connected to the push plate 51, and the heat conducting sheet 74 is arranged between each heat dissipation fin 72 in a close-fitting arrangement. Through this arrangement, the refrigerant liquid will be reset and flow back into the lower liquid shell 31 during the stamping operation, and the heat will be transferred to the heat conducting part 7. The air flow ejected by the air delivery part 13 dissipates heat from the heat conducting part 7. This operation can keep the refrigerant liquid at a low temperature at all times, providing good cooling conditions for the subsequent continuous cooling of the lower mold 4.The left and right notches at the lower part of the guide groove 16 are fixedly connected with elastic resistance members 17. The elastic resistance member 17 is an elastic metal member with a protrusion. Through this setting, the elastic resistance member 17 can immediately push the ejection part 5 downward to reset when the punching operation guide tube 14 moves downward, so that the ejection part 5 is reset in time. The inner side of the liquid guide 63 is provided with a middle hole and a plurality of liquid holes outside the middle hole. The bag sleeve 64 is a folding ring structure provided with a lower opening. The bag sleeve 64 is connected to the liquid guide 63. The holes are connected. By this arrangement, when the refrigerant liquid stored in the lower liquid shell 31 is compressed, it can only enter the bag sleeve 64 through the liquid hole of the liquid guide 63. The diameter of the ejector pin 54 is the same as the inner diameter of the middle hole of the liquid guide 63. The outer end surface of the heat conducting plate 74 fits with the inner wall of the gate opening 67. By this arrangement, the refrigerant liquid in the lower liquid shell 31 is prevented from leaking from the gate opening 67 and the middle hole of the liquid guide 63. The upper mold 2 and the lower mold 4 are arranged in a top-to-bottom manner. The upper end of the ejector block 55 is The surface is smoothly transitioned with the inner wall of the mold cavity 42. The inlet valve pipe 132 is composed of a one-way valve and an inlet pipe. The exhaust valve pipe 133 is composed of an inner one-way valve and an outer extendable pipe. This setting determines the inlet and exhaust directions of the gas transmission part 13. The exhaust heads 134 are arranged on the left and right sides of the heat conducting part 7. The exhaust heads 134 and the heat conducting part 7 are aligned horizontally. The heat dissipation fins 72 away from the exhaust port 35 do not have a vent 73. The exhaust port 35 is front and back to the vent 73. The alignment ensures that the air discharged from the exhaust head 134 into the upper expansion shell 32 is blown directly onto the heat sink fins 72. The airflow enters between the heat sink fins 72 from both sides, removes the heat, and is then discharged from the vents 73. It is then discharged from the exhaust port 35 directly opposite the vents 73, thereby dissipating heat from the heat sink fins 72. This operation ensures that the refrigerant liquid maintains a low temperature, providing good cooling conditions for the subsequent continued cooling of the lower mold 4.

[0017] like Figure 1 、 Figure 3 、 Figure 9 、 Figure 10 、 Figure 17As shown, the base part 3 is provided with a lubricating part 8, which includes a liquid tank 81 fixed on the upper side of the lower seat plate 11, a connecting pipe 82 communicated with the right side of the liquid tank 81, a bidirectional liquid pump 83 communicated with the right end of the connecting pipe 82, a liquid delivery pipe 84 communicated with the right side of the bidirectional liquid pump 83, a meter 85 installed on the liquid delivery pipe 84, a shunt pipe 86 communicated with the other end of the liquid delivery pipe 84 and located on the upper side of the lower liquid shell 31, a plurality of through pipes 87 communicated with the left side interface of the shunt pipe 86, a plurality of sleeve pipes 88 installed on the inner side of the upper expansion shell 32 and sleeved on the outer side of each capsule sleeve 64, a control box 89 installed on the front side of the liquid tank 81, and the control box 89 can control the operation of the bidirectional liquid pump 83 in a timed manner through the above arrangement. The lubricating oil is pumped from the liquid tank 81 through the connecting pipe 82, and then sent to the sleeve pipe 88 through the liquid delivery pipe 84, the shunt pipe 86 and the through pipe 87. After the lubricating oil reaches the sleeve pipe 88, it will be applied to the outer surface of the capsule sleeve 64. Then, the control box 89 controls the bidirectional liquid pump 83 to operate in reverse, and the lubricating oil is pumped back through the through pipe 87, the shunt pipe 86 and the liquid delivery pipe 84, and then flows back to the liquid tank 81 through the connecting pipe 82, completing the circulation. In this way, the surface of the capsule sleeve 64 is coated with oil at regular intervals, and the expansion of the capsule sleeve 64 can apply lubricating oil to the inner wall of the rod channel 43 during ejection and demolding. This process not only improves the smoothness of the ejection and demolding operation, but also greatly reduces the phenomenon of rod jamming caused by insufficient lubrication. The control box 89 is electrically connected with the meter 85 and the bidirectional liquid pump 83, the liquid tank 81 is composed of a lower tank body and an upper tank cover, and the staff can supplement the lubricating oil of the liquid tank 81 through the above arrangement.

The outer curved surface of the sealing ring 65 is in close contact with the inner wall of the rod channel 43, and the inner curved surface of the sealing ring 65 is in close contact with the outer curved surface of the ejector rod 54. Through the above arrangement, the lubricating oil in the sleeve pipe 88 can be prevented from leaking to the outside of the sleeve pipe 88.

[0018] Work flow: the heat dissipation cooling operation of the automobile parts processing die to prevent overheating is as follows, note one: the equipment is powered by external power supply, and is controlled through the control box 89; note two: the lower protruding part of the upper die 2 and the die cavity 42 of the lower die 4 are matched with each other, and the lower protruding part of the upper die 2 and the die cavity 42 of the lower die 4 can be adaptively adjusted and modified according to the shape of the automobile parts to be processed; note three: the inside of the lower liquid shell 31 is provided with refrigerant liquid, and the refrigerant liquid is on the upper side of the push flow plate 51, and the capsule sleeve 64 is in a contracted state; note four: the equipment is installed on the external punch machine, and the control of the external punch machine is realized through the controller on the body of the punch machine; note five: the lubricating oil is pre-stored in the liquid tank 81; stamping operation: the equipment needs to be used in cooperation with the external punch machine, and the lower seat plate 11 needs to be fixed on the workbench of the punch machine in advance, and the upper seat plate 12 is fixed on the punch head of the punch machine, and then the material plate is placed between the upper die 2 and the lower die 4, at this time, the downward movement of the punch head of the punch machine can drive the upper seat plate 12 and the upper die 2 to displace downward to perform the stamping operation on the workpiece, so that the material plate is pressed into the die cavity 42 of the lower die 4, and the automobile sheet metal part with the required shape is obtained, and the stamping operation is completed; ejection demolding operation: first, the punch head of the punch machine needs to be controlled to move upward, this action can drive the upper seat plate 12 to move upward and reset, with the displacement of the upper seat plate 12, the upper die 2 will also move upward, so as to separate from the matching state with the lower die 4, at this time, the upper die 2 no longer extrudes the automobile sheet metal part formed by stamping, so that the sheet metal part can be exposed from the die cavity 42 of the lower die 4, which fully prepares for the subsequent sheet metal demolding operation and the safety of the staff taking the plate; at the same time, the upward movement of the upper seat plate 12 also drives the air inlet frame tube 131 of the air inlet part 13 and each conduit 14 to move upward, the upward displacement of each conduit 14 will cause the relative displacement of the piston guide column 15, so as to draw air outside through the air inlet frame tube 131 and each air inlet valve tube 132, and store the gas in the inside of the conduit 14, which prepares for the exhaust in the subsequent next stamping operation; when each conduit 14 moves up to be limited by the piston guide column 15, it indicates that the conduit 14 has been displaced to the maximum value, and the guide groove 16 moving upward with the conduit 14 will lift the linkage bar 53 of the ejection part 5, in this process, the linkage bar 53 will pass through a group of elastic resistance members 17, and be located on the lower side of the elastic resistance members 17 (such as Figure 20The upper movement of the linkage bar 53 will drive the push flow plate 51 to move up through the linkage rod 52, and then drive each top rod 54 and top block 55 to move upward, and finally the top block 55 is pushed out from the upper part of the rod channel 43, and the automobile sheet metal part in the mold cavity 42 is pushed out from the lower mold 4, and the ejection demolding operation is completed; the heat dissipation cooling operation: during the ejection demolding operation, the upward movement of the push flow plate 51 will produce a squeezing effect on the refrigerant liquid located on its upper side, and this squeezing effect will force the refrigerant liquid in the lower liquid shell 31 to flow into each bladder sleeve 64 through each liquid guide 63. With the gradual increase of the refrigerant liquid in the bladder sleeve 64, the bladder sleeve 64 will expand and unfold upward under the guidance of the sealing ring 65 and the top rod 54, and the unfolded bladder sleeve 64 will pass through and fill the entire rod channel 43, and force the spring 66 to contract; at this time, the refrigerant liquid in the bladder sleeve 64 can effectively exchange heat with the rod channel 43 and the top rod 54, and this heat exchange process can cool each rod channel 43 in the lower mold 4, thereby avoiding the rod jamming in the subsequent ejection demolding operation. Through the above operation, the cooling treatment of the inside of the lower mold 4 is completed, so the device can cool the inside of the lower mold 4 through the original rod channel 43 without needing to open a new refrigerant liquid passage; at the same time, the heat of the mold body 41 of the lower mold 4 can also be transmitted to the heat conduction part 7 through conduction, and then dissipated through the heat conduction part 7, realizing the heat dissipation and cooling of the surface of the lower mold 4. Through this double cooling measure, the overheat of the automobile part processing die during use can be effectively avoided, and the normal operation of the die and the quality of part processing are ensured; the heat dissipation operation in the next stamping action: after the formed and demolded automobile part is taken down, a new material plate needs to be placed between the upper mold 2 and the lower mold 4, and then the stamping machine equipment is controlled to start the stamping action again. At this time, the upper seat plate 12 will move downward together with the upper mold 2 to perform the stamping operation on the newly placed material plate, so that it is pressed into the mold cavity 42 of the lower mold 4, thereby obtaining a new automobile sheet metal part with the required shape; at the same time, the downward movement of the upper seat plate 12 will drive each conduit 14 to move downward through the air passage frame tube 131, and the downward movement of the conduit 14 will be limited by the elastic resistance piece 17, directly pushing the linkage bar 53 and the linkage rod 52 to move downward and reset. This process will further push the push flow plate 51, the top rod 54, the top block 55, and the heat conduction fin 74 to move downward and reset. The downward reset of the push flow plate 51 will increase the distance between it and the partition plate 61, thereby making the lower liquid shell 31 regain the liquid storage capacity. At this time, each spring 66 will reset and expand to squeeze the previously expanded bladder sleeve 64, so that the refrigerant liquid in the bladder sleeve 64 flows back to the lower liquid shell 31 with the heat of the lower mold 4, and the refrigerant liquid in the lower liquid shell 31 will contact the heat conduction fin 74 to conduct heat to the heat dissipation fin 72 through the heat conduction fin 74;With the continuous downward movement of the guide pipe 14, the linkage strip 53 will be forced to extrude the elastic resistance 17, and then the linkage strip 53 will displace upward in the guide groove 16 beyond the elastic resistance 17, at this time, the downward movement of the guide pipe 14 will cause the relative displacement of the piston guide column 15, so that the gas stored in the guide pipe 14 is discharged into the upper expansion shell 32 through the venting frame pipe 131, the exhaust valve pipe 133 and the exhaust head 134, which will directly blow on each heat dissipation fin 72, and the airflow will enter between the heat dissipation fins 72 from both sides, and then be discharged from the exhaust port 35 after taking away the heat; in this way, the heat dissipation fin 72 can be cooled once for each stamping operation of the equipment, which can keep the refrigerant liquid at a low temperature all the time, providing good cooling conditions for the continuous cooling of the lower die 4, which realizes the automatic cooling of the automobile part processing die during the stamping process through double cooling measures, without increasing power consumption and affecting the strength of the die, which effectively solves the problem that the existing automobile part processing die is prone to overheating during long-time and frequent stamping, thereby affecting the demolding operation, and the existing cooling method has limited cooling performance, affects the strength of the die, and usually needs to increase the power consumption for cooling; lubrication operation: the control box 89 can control the operation of the bidirectional liquid pump 83 at regular intervals, after the bidirectional liquid pump 83 is started, the lubricating oil is extracted from the liquid tank 81 through the connecting pipe 82, and then is delivered to each sleeve pipe 88 through the liquid delivery pipe 84 and the shunt pipe 86, in the delivery process, the amount of lubricating oil can be accurately controlled by the meter 85 to ensure that the amount of lubricating oil delivered each time is consistent; when the lubricating oil reaches each sleeve pipe 88, it will come into contact with the capsule 64 in the contracted state and be applied to the outer surface of the capsule 64, at this time, the control box 89 controls the bidirectional liquid pump 83 to operate in reverse again, and the lubricating oil in the sleeve pipe 88 is pumped back through the pipe 87, the shunt pipe 86 and the liquid delivery pipe 84, and then is returned to the liquid tank 81 through the connecting pipe 82, completing a cycle; through the reciprocating circulation of the lubricating oil, the surface of the contracted capsule 64 can be coated with lubricating oil at regular intervals, so that the lubricating oil can be applied to the inner wall of the rod way 43 every time the capsule 64 expands and unfolds during the ejection and demolding operation, which not only improves the smoothness of the ejection and demolding operation, but also greatly reduces the phenomenon of rod jamming caused by insufficient lubrication, avoids damage to the die and parts caused by rod jamming, thereby prolonging the service life of the die, improving the production efficiency and reducing the production cost.
