[0037] The heat dissipation module 3 is installed on the die base body 1 and provides air flow contacting with the automobile parts; the heat dissipation module 3 provides heat dissipation for the automobile parts and the cutter module 2; the heat dissipation module 3 does not need to use wet materials such as cooling liquid and lubricating liquid; the heat dissipation module 3 utilizes heat conduction and heat exchange to cooperate with air flow to accelerate the air flow speed on the surface of the cutter module 2 and the automobile parts to physically dissipate heat for the cutter module 2 and the automobile parts.

[0038] The lower die seat 12 is provided with a driving structure 14, the driving end of the driving structure 14 is connected with a clamping structure 15 for fixing the automobile parts, and the driving structure 14 drives the clamping structure 15 to rotate with the automobile parts to realize cutting; the driving structure 14 can adopt a driving motor, and the driving end is the rotating shaft connected with the driving motor; the clamping structure 15 can adopt a fixed clamp seat or a fixed clamp jaw, and the side of the fixed clamp seat or the fixed clamp jaw away from the driving structure 14 is further provided with a fixed-point pivoting ring; the automobile parts are inserted into the fixed-point pivoting ring and clamped and fixed by the fixed clamp seat or the fixed clamp jaw; the fixed-point pivoting ring can prevent the automobile parts from deviating.

[0039] The chip removal module 4 is arranged on the lower die seat 12 and below the cutter module 2 to provide discharge of the cutting chips; the chip removal module 4 can adopt an inclined groove or a spiral groove, and the end is connected with a negative pressure suction device such as an air suction pump; the negative pressure suction device is used to suck the air and the chips above the lower die seat 12 into the chip removal module 4 to cooperate with the heat dissipation structure to accelerate the air flow speed at the lower die seat 12, improve the cooling efficiency, and facilitate the discharge of the chips; a recycling box can be arranged beside the negative pressure suction device to facilitate the unified recycling of the chips.

[0040] Specifically, after the upper die seat 11 and the lower die seat 12 are opened, the accessory to be cut is clamped by the clamping structure 15, then the upper die seat 11 covers the lower die seat 12, and the upper die seat 11 and the lower die seat 12 are locked and fixed by the locking structure 13, the driving structure 14 drives the accessory to rotate at high speed along the cutter structure to realize cutting, and the heat dissipation structure accelerates the air flow speed around the cutter module 2 and the accessory to provide physical cooling, and at the same time, the cuttings are discharged and collected by the airflow and the chip removal module 4, so as to provide the cooling and temperature reduction of the accessory and the cutter module 2 without cooling liquid.

[0041] Further, referring to Figure 2 As shown in the figure, the heat dissipation cavity 16 is provided in the mold base, and the upper die seat 11 and the lower die seat 12 are provided with a plurality of heat dissipation holes 17, and the heat dissipation structure is installed in the heat dissipation cavity 16. The heat dissipation cavity 16 is used to provide the installation of the accessory and the driving structure 14, and when a part of the accessory is in the heat dissipation cavity 16, the air flow speed in the heat dissipation cavity 16 is increased, which can realize heat exchange more quickly, and the heat is discharged quickly through the heat dissipation holes 17.

[0042] In some embodiments, referring to Figure 2 As shown in the figure, the heat dissipation module 3 includes a cutter heat dissipation structure 33, an accessory heat dissipation structure 31 and an airflow heat dissipation structure 32; the accessory heat dissipation structure 31 is installed in the heat dissipation cavity 16, and the accessory heat dissipation structure 31 is mainly used to provide heat dissipation for the accessory located in the heat dissipation cavity 16, and mainly for the accessory that stops rotating. The accessory heat dissipation structure 31 contacts the accessory after the accessory stops rotating, thereby quickly absorbing the heat on the accessory to realize heat conduction and heat exchange, so as to quickly reduce the high temperature and high heat on the accessory.

[0043] The cutter heat dissipation structure 33 is connected with the cutter module 2 and the accessory heat dissipation structure 31, and the cutter heat dissipation structure 33 is similar to the accessory heat dissipation structure 31, but the cutter heat dissipation structure 33 can also be connected with the accessory heat dissipation structure 31. Part of the heat of the cutter heat dissipation structure 33 is exchanged with the external air, and the other part is transmitted to the accessory heat dissipation structure 31 for heat exchange, thereby increasing the heat exchange rate.

[0044] The airflow heat dissipation structure 32 is installed in the upper die seat 11 to provide heat dissipation airflow. The airflow heat dissipation structure 32 can generate airflow, and the air cooling effect of the airflow directly cools the cutter module 2 and the accessory, which further increases the cooling efficiency in cooperation with the accessory heat dissipation structure 31 and the cutter heat dissipation structure 33.

[0045] Specifically, part of the heat of the accessory is quickly exchanged through the accessory heat dissipation structure 31, the tool heat dissipation structure 33 exchanges heat with the tool module 2 and at the same time transmits part of the heat of the tool module 2 to the accessory heat dissipation module 3 for heat dissipation, and the air cooling flow generated by the air flow heat dissipation structure 32, so as to accelerate the heat exchange rate of the tool heat dissipation structure 33 and the accessory heat dissipation structure 31, and further increase the cooling effect.

[0046] In some embodiments, with reference to Figure 2 As shown, the accessory heat dissipation structure 31 is composed of an array of metal heat dissipation pipes, which are divided into upper and lower arrays. The upper array 311 is connected with the upper die holder 11, and the lower array 312 is connected with the lower die holder 12, so that when the upper and lower die holders 12 are separated or combined, the upper and lower arrays are separated or closely attached.

[0047] The upper array 311 is provided with an upper half contact pipe 313, and the lower array 312 is provided with a lower half contact pipe 314. The upper half contact pipe 313 wraps the upper half surface of the accessory, and the lower half contact pipe 314 wraps the lower half surface of the accessory. When the upper half contact pipe 313 and the lower half contact pipe 314 wrap the accessory at the same time, the heat of the surface of the accessory is quickly transmitted to the upper half contact pipe 313 and the lower half contact pipe 314. The upper half contact pipe 313 and the lower half contact pipe 314 then transmit the heat to the metal heat dissipation pipes of the upper array 311 and the lower array 312 respectively, thereby expanding the heat dissipation area and accelerating the heat dissipation efficiency.

[0048] With reference to Figure 2 and Figure 3 As shown, the heat dissipation cavity 16 is provided with a sliding groove 315. The upper array 311 and the lower array 312 are both slidingly connected with the heat dissipation cavity 16 through the sliding groove 315. The sliding groove 315 of the upper die holder 11 and the lower die holder 12 is a half sliding groove 315. When the upper die holder 11 and the lower die holder 12 are combined, the two half sliding grooves 315 are attached to form a complete sliding groove 315. The metal heat dissipation pipes of the upper array 311 and the lower array 312 can slide through the sliding groove 315, avoiding the position deviation of the upper array 311 and the lower array 312, and ensuring that the upper half contact pipe 313 and the lower half contact pipe 314 can accurately wrap the accessory.

[0049] The inner side wall of the mold base is also provided with an air flow cavity 316. The air flow cavity 316 is also divided into two halves, which are located on the upper die holder 11 and the lower die holder 12 respectively. When the upper die holder 11 and the lower die holder 12 are combined, the air flow cavity 316 is attached completely. The air flow cavity 316 of the upper die holder 11 and the lower die holder 12 is also provided with a sealing rubber at the attached position, so that after the two are attached, it is ensured that there is no air leakage.

[0050] The airflow cavity 316 is provided with a communication port between the sliding groove 315, and the communication port is provided with two, which are respectively located in the upper die seat 11 and the lower die seat 12, so that the airflow can flow into the corresponding sliding groove 315 of the upper die seat 11 and the lower die seat 12 through the communication port.

[0051] The upper die seat 11 and the lower die seat 12 are respectively provided with a closing plug 317 and an elastic part 318 in the corresponding sliding groove 315, the closing plug 317 slides along the sliding groove 315, one end of the elastic part 318 is connected with the closing plug 317, and the other end is connected with the groove wall of the sliding groove 315, and the elastic part 318 provides the elastic force of the closing plug 317, and the upper array 311 or the lower array 312 is connected with the corresponding closing plug 317, that is, the upper array 311 is connected with the closing plug 317 in the corresponding sliding groove 315 of the upper die seat 11, and the lower array 312 is connected with the closing plug 317 in the corresponding sliding groove 315 of the lower die seat 12.

[0052] Specifically, when the airflow cooling structure 32 provides air pressure and airflow supply to the airflow cavity 316, the airflow enters the sliding groove 315 from the communication port, at this time, the air pressure is generated in the sliding groove 315, so as to provide the air pressure for the closing plug 317, after the closing plug 317 is supplied by the air pressure, it moves along the sliding groove 315, and drives the upper array 311 or the lower array 312 to move to the accessory, so as to wrap the accessory and exchange heat with the accessory, and quickly reduce the heat generated by the accessory, when the airflow cooling structure 32 does not provide airflow and air pressure, the closing plug 317 is reset by the elastic force of the elastic part 318, so that the upper array 311 and the lower array 312 are separated from the accessory.

[0053] Wherein, when the closing plug 317 moves to the slot opening of the sliding groove 315 connected with the upper array 311 or the lower array 312, the airflow can flow into the heat dissipation cavity 16 through the slot opening of the sliding groove 315, so that the airflow can cool the upper array 311 and the lower array 312 in the heat dissipation cavity 16.

[0054] Wherein, with reference to Figure 3As shown, the air pressure sensor 319 can also be arranged in the sliding groove 315, and the air pressure sensor 319 is electrically connected with the air flow heat dissipation structure 32. The air flow heat dissipation structure 32 is pre-set with a rated air pressure. When the closing plug 317 moves to the slot opening of the sliding groove 315, the air flow will flow from the sliding groove 315 to the heat dissipation cavity 16, so that the air pressure in the sliding groove 315 changes and is lower than the rated air pressure. The air pressure sensor 319 transmits feedback information to the air flow heat dissipation structure 32 through an electrical signal. The air flow heat dissipation structure 32 increases the power and the air flow and air pressure, so that the rated air pressure in the sliding groove 315 can be maintained to ensure the stable position of the closing plug 317, avoid the resetting of the closing plug 317 due to the elastic force of the elastic part 318 when the air pressure is low, and increase the air pressure to increase the air flow speed and the air flow speed in the heat dissipation cavity 16 to speed up the heat dissipation efficiency.

[0055] In the formula, the reference Figure 4 As shown, when the number of metal heat dissipation pipes of the upper array 311 or the lower array 312 is too large, an additional sliding rail 19 can be arranged to provide auxiliary guidance to avoid the deviation of the metal heat dissipation pipes of the upper array 311 or the lower array 312. The sliding rail 19 can also be provided with an elastic part 318 to provide resetting to ensure the stability of the resetting effect when there is no air pressure supply. The sliding rail 19, the accessory and the clamping structure 15 in the figure are staggered.

[0056] In the formula, the reference

[0057] Further, as shown in the formula Figure 3 As shown, the closing plug 317 is provided with a suction accessory 34 near one end of the communication port. The suction accessory 34 can be made of a material with magnetic attraction effect, such as an iron sheet. The sliding groove 315 is provided with an electromagnet 35. The connection mode of the electromagnet 35 can be embedded in the groove wall of the sliding groove 315 to ensure that the closing plug 317 will not be blocked and ensure smooth movement. The electromagnet 35 is electrically connected with the driving structure 14. The electrical connection can be a signal connection. When the electromagnet 35 is powered, the electromagnet 35 generates magnetism to fix the closing plug 317 together with the suction accessory 34, so that even if the air pressure in the sliding groove 315 is increased, the closing plug 317 will not move. This way is to ensure that the closing plug 317 will not move when the driving structure 14 drives the accessory to rotate, so as not to cause damage to the upper array 311 or the lower array 312 moving to the wrapped accessory.

[0058] Specifically, when the driving structure 14 drives the accessory to rotate, the electromagnet 35 is opened synchronously through the electrical connection, the electromagnet 35 generates magnetism to attract the suction accessory 34, so that the closing plug 317 cannot move, ensuring that the upper array 311 and the lower array 312 cannot move to the accessory, ensuring that the accessory can normally perform cutting.

[0059] Further, referring to Figure 2 or Figure 4 It is shown that the mold base away from the driving structure 14 one end is also provided with a flow guide groove 18, and the upper mold base 11 is also provided with a gas supply channel 111, the gas supply channel 111 is communicated with the top of the flow guide groove 18, the airflow cooling structure 32 is installed on the upper mold base 11 and communicated with the gas supply channel 111, the flow guide groove 18 is used to align the airflow generated by the airflow cooling structure 32 to the accessory, thereby avoiding the loss of airflow, and the gas supply channel 111 provides the airflow generated by the airflow cooling structure 32 with transportation, the flow guide groove 18 is a circular groove, and the upper mold base 11 and the lower mold base 12 are each provided with a half, and the two are combined to form a complete flow guide groove 18.

[0060] The tool structure is located in the flow guide groove 18, so that after the flow guide groove 18 is complete, it not only provides the guidance of airflow and debris, but also provides the anti-splashing effect, avoiding the random splashing of debris generated during cutting, making the processing environment dangerous.

[0061] The bottom of the flow guide groove 18 is provided with a chip removal port 41 of the chip removal module 4, that is, the bottom of the flow guide groove 18 of the lower mold base 12, the chip removal port 41 is communicated with the flow guide groove 18, when the airflow cooling structure 32 transports the airflow to the flow guide groove 18 through the gas supply channel 111, the airflow flows along the groove wall of the flow guide groove 18 to the chip removal port 41 after contacting the accessory, and the negative pressure suction device of the chip removal structure discharges the debris and the airflow with heat from the chip removal port 41.

[0062] Specifically, the airflow of the airflow cooling structure 32 is transported to the flow guide groove 18 by the gas supply channel 111, the accessory is located in the flow guide groove 18 for cutting, the airflow contacts the accessory after entering the flow guide groove 18, thereby reducing the heat generated by the accessory, and the airflow is guided to the chip removal port 41 by the flow guide groove 18, and the debris is discharged into the chip removal structure, to realize the air cooling effect of the airflow cooling structure 32 during and after cutting.

[0063] Further, referring to Figure 2 or Figure 4As shown, the air flow cavity 316 is in communication with the air supply channel 111, so that when the air flow heat dissipation structure 32 provides air flow supply, it not only delivers air flow to the air supply channel 111, but also to the air flow cavity 316, so that the cooling in the heat dissipation cavity 16 is achieved without affecting the air cooling heat dissipation in the flow guide groove 18. After the closure plug 317 is fixed by the magnetic force of the electromagnet 35, the air supply channel 111 still provides air cooling heat dissipation, realizing multi-directional air cooling heat dissipation.

[0064] Further, the air flow heat dissipation structure 32 includes air pumps, which are installed on the top of the upper mold base 11 and in communication with the air flow cavity 316, which is in communication with the air supply channel 111, so that when the air pump provides air flow and air pressure supply, it provides bidirectional supply. Multiple air pumps are provided to ensure stable supply of air pressure and air flow.

[0065] In some embodiments, referring to Figure 5 As shown, the tool heat dissipation structure 33 includes a metal heat dissipation frame 331, which is connected with the tool structure. The connection mode can be fixed connection or embedded connection, which is determined by the requirement and is not limited herein. The metal heat dissipation frame 331 extends into the heat dissipation cavity 16 and is in contact with the accessory heat dissipation structure 31. The heat generated during cutting of the tool module 2 is exchanged by the metal heat dissipation frame 331. Part of the heat exchanged metal heat dissipation frame 331 is in contact with the external air, and the air flow blown from the air flow heat dissipation structure 32 through the air passage to accelerate the cooling efficiency. The other part extends into the heat dissipation cavity 16 and is in contact with the accessory heat dissipation structure 31, so that the heat is transferred to the accessory heat dissipation structure 31. Since the heat dissipation area of the accessory heat dissipation structure 31 is large, it can provide faster and more effective heat dissipation effect. At the same time, the internal heat dissipation cavity 16 is also supplied with air flow by the air flow heat dissipation structure 32, so that the heat dissipation efficiency is higher.

[0066] Since the upper array 311 and the lower array 312 move along the sliding groove 315, the connection mode of the metal heat dissipation frame 331 with the upper array 311 or the lower array 312 is contact connection, so that the upper array 311 or the lower array 312 can slide up and down along the surface of the metal heat dissipation frame 331, and the contact is not disconnected, thereby providing heat exchange without affecting the movement of the upper array 311 and the lower array 312.

[0067] The part of the metal heat dissipation frame 331 located in the flow guide groove 18 is provided with a support block to stabilize the tool structure in case of vibration during cutting. The top surface of the part located in the flow guide groove 18 is also provided with a "herringbone" inclined surface to ensure that the debris falling on the metal heat dissipation frame 331 can fall into the chip discharge port 41 along with the air flow and the inclined surface.

[0068] In some embodiments, referring to Figure 6As shown, the clamping structure 15 is provided with air flow fan blades 151, and the clamping structure 15 rotates synchronously with the driving end of the driving structure 14, so that the clamping structure 15 rotates to drive the air flow fan blades 151 to rotate. At this time, there are two different ways of forming air flow in the heat dissipation cavity 16. One is the air flow transported by the air flow dissipation structure 32 through the air flow cavity 316, the communication port and the sliding groove 315. The second is the air flow formed by the air flow fan blades 151 rotating through the clamping structure 15 when the driving structure 14 rotates. These two ways can provide heat dissipation air flow in different situations.

[0069] The first way is that after cutting is completed, the driving structure 14 stops rotating, the electromagnet 35 is powered off, and the closing plug 317 is driven to wrap the upper array 311 and the lower array 312 around the accessory to provide heat exchange, and the air flow is simultaneously transported through the slot of the sliding groove 315 to accelerate the heat exchange rate. The second way is that during cutting, the electromagnet 35 generates a magnetic force to fix the position of the closing plug 317, and at this time, the air flow fan blades 151 rotate with the driving structure 14 to generate heat dissipation air flow. Therefore, the heat dissipation cavity 16 can generate heat dissipation air flow from different structures according to the cutting process to ensure the stability of heat dissipation.

[0070] In the first way, the slot of the sliding groove 315 can also be made deeper, and the closing plug 317 will not move after being fixed by the electromagnet 35, and the air flow can also be transported through the slot of the sliding groove 315. This way can also make up for the insufficient air flow generated by the air flow fan blades 151, and the air pressure sensor 319 can adjust the air pressure at any time to ensure the transportation of air flow.

[0071] When the air flow fan blades 151 are provided, the metal heat dissipation pipes of the upper array 311 and the lower array 312 need to be spaced apart to provide a space for the rotation of the air flow fan blades 151, so as to avoid contact and damage.

[0072] The embodiments of the specific implementation are the preferred embodiments of the present application, and are not limited to the protection scope of the present application. The same parts are indicated by the same reference numerals. Therefore, equivalent changes made according to the structure, shape and principle of the present application should be covered by the protection scope of the present application.
