[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] Example: See Figure 1 - Figure 6 A quenching cooling device for mold processing includes a cooling box 1, a cooling pipe can be installed inside the cooling box 1 to cool the coolant, a liquid inlet pipe 2 is installed on the outer wall of one side of the cooling box 1, and a plurality of liquid discharge pipes 3 are installed at the bottom of the cooling box 1, and also includes:

[0046] The sinking mechanism is arranged inside the cooling box 1 and is used to drive the quenched mold to sink into the coolant. The sinking mechanism includes two transmission shafts 4 arranged inside the cooling box 1, two first reciprocating screws 5 respectively fixedly sleeved on the outside of the two transmission shafts 4, and two connecting blocks 6 respectively screwed on the outside of the two first reciprocating screws 5; a ring 7 is fixedly connected between the two connecting blocks 6, and a plurality of supporting blocks 8 are fixedly connected to the bottom of the inner side of the ring 7, and the mold mouth is placed downward on the top of the plurality of supporting blocks 8;

[0047] By driving the two transmission shafts 4 to rotate synchronously, the two first reciprocating screws 5 rotate synchronously, thereby driving the connecting block 6 to move downward from the top end of the first reciprocating screw 5 to its bottom end, thereby driving the ring 7 to move downward synchronously, and then driving the mold on the top of the inner support block 8 of the ring 7 to move downward synchronously, and immerse it in the coolant to cool the quenched mold. After the mold is cooled, by continuing to drive the transmission shaft 4 and the first reciprocating screw 5 to rotate, the ring 7 and the mold are driven to move upward and reset.

[0048] The active positioning mechanism is connected to the sinking mechanism and is used to automatically fix the mold when it sinks and to automatically release the mold when it moves up. The active positioning mechanism is provided with two and is respectively installed on both sides of the ring 7; the active positioning mechanism includes a through groove 9 opened inside the ring 7, a screw sleeve 10 rotatably connected inside the through groove 9, a one-way screw 11 screwed inside the screw sleeve 10 and a linkage component for driving the screw sleeve 10 to rotate; one end of the one-way screw 11 extends to the inside of the ring 7 and is fixed A clamping block 12 is connected, a telescopic rod 13 is fixedly connected to the outer wall of one side of the clamping block 12, and the other end of the telescopic rod 13 is fixedly connected to the inner wall of the ring 7. The linkage assembly includes a slider 14 rotatably sleeved on the outside of the transmission shaft 4, a first rack 15 fixedly connected to the bottom of the slider 14, and a first gear 16 fixedly sleeved on the outside of the screw sleeve 10; the first rack 15 is meshed with the first gear 16; a slide groove 17 of an annular structure is opened on the inner wall of the cooling box 1, and one end of the slider 14 is slidably connected to the inside of the slide groove 17 along the annular track;

[0049] When the ring 7 moves downward, the screw sleeve 10 and the first gear 16 outside it are driven to move downward synchronously, and the first rack 15 remains stationary. The screw sleeve 10 is driven to rotate through the meshing effect between the first gear 16 and the first rack 15. Through the limiting effect of the telescopic rod 13, the one-way screw 11 is driven to move toward the inside of the ring 7, thereby driving the clamping block 12 to move synchronously to clamp the mold. The first gear 16 and the first rack 15 lose meshing at the same time, so that when the ring 7 rotates, the mold is driven to rotate synchronously;

[0050] When the two transmission shafts 4 make a revolution around the first driving shaft 19, the slider 14 is driven to slide synchronously along the inner wall of the slide groove 17. Therefore, the slider 14 will not rotate with the rotation of the transmission shaft 4, but will only slide along the annular track of the slide groove 17, and the first rack 15 will slide synchronously therewith.

[0051] When the ring 7 moves upward, the screw sleeve 10 and the first gear 16 outside it are driven to move upward synchronously. When the first gear 16 re-engages with the first rack 15, the screw sleeve 10 is driven to rotate in the opposite direction, thereby driving the one-way screw 11 to move toward the inside of the screw sleeve 10, and then driving the clamping block 12 away from the mold, thereby releasing the fixation of the mold, making it easier for the staff to remove the cooled mold.

[0052] The steam exhaust mechanism is connected to the sinking mechanism and is used to drive the fixed mold to rotate when the mold sinks to exhaust the steam inside the mold. The steam exhaust mechanism includes a bracket 18 installed on the top of the cooling box 1, a first driving shaft 19 rotatably connected to the top of the bracket 18, a driving bar 20 fixedly sleeved on the outside of the first driving shaft 19, and a gear ring 21 fixedly connected to the inner wall of the top of the bracket 18; the two ends of the driving bar 20 are respectively rotatably sleeved on the outside of the two transmission shafts 4; the outside of the two transmission shafts 4 are fixedly sleeved with a second gear 22, and the second gear 22 is meshed with the gear ring 21; the first driving shaft 19 is connected to the driving mechanism;

[0053] The first drive shaft 19 is driven to rotate by the driving mechanism, and the drive bar 20 rotates synchronously therewith, thereby driving the two transmission shafts 4 to perform orbital motion with the first drive shaft 19 as the center. In this process, the first drive shaft 19 is driven to rotate by the meshing effect between the second gear 22 and the gear ring 21, and the first reciprocating screw 5 rotates therewith, thereby driving the ring 7 to rotate and move downward, and then driving the mold to rotate and move downward in the coolant. In this process, the steam generated by cooling inside the mold is quickly discharged, avoiding the problem of large difference in cooling effect inside and outside the mold due to the obstruction of steam discharge due to the complex internal structure of the mold. At the same time, it can accelerate the flow speed of the coolant inside the mold to prevent the coolant from not flowing inside the complex mold, resulting in the problem of poor cooling effect inside the mold. When the ring 7 is driven to rotate and move upward, the coolant inside the cooling box 1 is discharged, and the mold is driven to rotate and move upward at the same time. In this process, the coolant remaining in the mold is thrown out by centrifugal force, avoiding the problem of easy to carry coolant and inconvenient discharge due to the complex internal structure of the mold.

[0054] An active liquid replacement mechanism is installed on the cooling box 1 and is used to automatically replace the coolant inside the cooling box 1 after the current mold is cooled. The active liquid replacement mechanism includes a second driving shaft 23 rotatably connected to the inside of the bracket 18, a second reciprocating screw 24 fixedly sleeved on the outside of the second driving shaft 23, and a driven shaft 25 rotatably connected to the inner wall of the cooling box 1; a lifting block 26 is screwed to the outside of the second reciprocating screw 24, and a second rack 27 is fixedly connected to the bottom of the lifting block 26; a guide rod 28 is also fixedly connected to the bottom of the bracket 18, and the lifting block 26 is also slidably sleeved on the outside of the guide rod 28; a sealing disk 29 is fixedly sleeved on the outside of the driven shaft 25, one end of the driven shaft 25 extends to the outside of the cooling box 1, and a one-way gear 30 is installed, and the one-way gear 30 is meshed with the second rack 27; the second driving shaft 23 is connected to the driving mechanism;

[0055] The second drive shaft 23 is driven to rotate by the driving mechanism, and the second reciprocating screw 24 is synchronously rotated accordingly, driving the lifting block 26 to move downward from the top end of the second reciprocating screw 24 to the bottom end thereof. In this process, the second rack 27 is driven to move downward synchronously, and the one-way gear 30 is synchronously rotated accordingly, but the driven shaft 25 does not rotate accordingly, and the sealing disk 29 does not rotate either;

[0056] After the mold is cooled, the second drive shaft 23 continues to rotate through the driving mechanism, and the second reciprocating screw 24 rotates synchronously therewith, driving the lifting block 26 to move from the bottom end of the second reciprocating screw 24 to its top end. In this process, the second rack 27 is driven to move upward synchronously. At this time, the driven shaft 25 is driven to rotate 360° through the meshing effect between the second rack 27 and the one-way gear 30, thereby driving the sealing disk 29 to flip a circle, so that the coolant inside the cooling box 1 is completely discharged through the drain pipe 3. After the sealing disk 29 is reset, new coolant is added to the cooling box 1 through the liquid inlet pipe 2, thereby realizing automatic replacement of the coolant.

[0057] A driving mechanism, which is installed above the cooling box 1, is used to drive the exhaust mechanism and the active liquid exchange mechanism to operate respectively, and the driving mechanism includes a motor 31 and two transmission members 32 installed on the top of the bracket 18; one of the transmission members 32 is transmission-connected between the output shaft of the motor 31 and the first drive shaft 19, and the other transmission member 32 is transmission-connected between the output shaft of the motor 31 and the second drive shaft 23. The transmission member 32 includes two synchronous wheels and a synchronous belt transmission-connected between the two synchronous wheels, wherein the two synchronous wheels in one of the transmission members 32 are respectively fixedly sleeved on the output shaft of the motor 31 and the outside of the first drive shaft 19, and the two synchronous wheels in the other transmission member 32 are respectively fixedly sleeved on the output shaft of the motor 31 and the outside of the second drive shaft 23;

[0058] The output shaft of the control motor 31 is driven to rotate, and the first drive shaft 19 and the second drive shaft 23 are driven to rotate through the transmission connection of the two transmission members 32 .

[0059] Working principle: When in use, the staff places the quenched mold mouth downward on the top of multiple support blocks 8, and drives the first drive shaft 19 to rotate through the driving mechanism, and the drive bar 20 rotates synchronously, thereby driving the two transmission shafts 4 to revolve around the first drive shaft 19. In this process, the first drive shaft 19 is driven to rotate by the meshing effect between the second gear 22 and the gear ring 21, and the first reciprocating screw 5 rotates accordingly, thereby driving the ring 7 to rotate and move downward. When the ring 7 moves downward, the screw sleeve 10 and the first gear 16 outside it are driven to move downward synchronously, and the first rack 15 remains stationary. The screw sleeve 10 is driven to rotate by the meshing effect between the first gear 16 and the first rack 15. The one-way screw 11 is driven to move toward the inside of the circular ring 7 through the limiting effect of the telescopic rod 13, thereby driving the clamping block 12 to move synchronously to clamp the mold. As the circular ring 7 rotates and moves downward, the mold is driven to rotate and move downward in the coolant. In this process, the steam generated by cooling inside the mold is quickly discharged, avoiding the problem of large difference in cooling effect inside and outside the mold due to obstruction of steam discharge due to the complex internal structure of the mold. At the same time, the flow speed of the coolant inside the mold can be accelerated to prevent the coolant from not flowing inside the complex mold, which leads to the problem of poor cooling effect inside the mold. When the circular ring 7 is driven to rotate and move upward, the coolant inside the cooling box 1 is discharged. The mold is driven out while rotating and moving upward. In this process, the coolant remaining in the mold is thrown out by centrifugal force, avoiding the problem that the coolant is not easy to discharge due to the complex internal structure of the mold. After the mold is cooled, the first drive shaft 19 and the second drive shaft 23 are continued to be driven to rotate by the driving mechanism. When the second drive shaft 23 rotates, the second reciprocating screw 24 rotates synchronously, driving the lifting block 26 to move from the bottom end of the second reciprocating screw 24 to its top end. In this process, the second rack 27 is driven to move upward synchronously. At this time, the second rack 27 is meshed with the one-way gear 30 to drive the driven shaft 25 to rotate 360°, thereby driving the sealing disk 29 to flip a circle, thereby The coolant inside the cooling box 1 is completely discharged through the drain pipe 3. When the first drive shaft 19 rotates, it drives the ring 7 and the mold to rotate and move upward. In this process, the coolant remaining in the mold is thrown out by centrifugal force, avoiding the problem that the coolant is easy to carry and is inconvenient to discharge due to the complex internal structure of the mold. At the same time, when the ring 7 moves upward, it drives the screw sleeve 10 and the first gear 16 outside it to move upward synchronously. When the first gear 16 re-engages with the first rack 15, it drives the screw sleeve 10 to rotate in the opposite direction, thereby driving the one-way screw 11 to move toward the inside of the screw sleeve 10, and then driving the clamping block 12 away from the mold, thereby releasing the fixation of the mold, and making it convenient for the staff to remove the cooled mold.
