A plurality of air holes 31 are provided in a rectangular distribution on the support plate 3, and a first one-way valve 311 is provided in each air hole 31; a closing component 15 is provided inside the connecting pipe 12, which can open and block the connecting pipe 12 as the supporting plate 3 moves; the shifting mechanism 5 is provided in the cooling box 2 The interior can rotate the mounting column 11 as the supporting plate 3 moves; a plurality of drainage holes 32 are arranged in a matrix on the supporting plate 3, the opening and closing mechanism 6 is arranged at the bottom of the supporting plate 3 and can seal and open the air holes 31 and the drainage holes 32 as the supporting plate 3 moves; conveyor belts 24 for transporting cylinder head blanks are arranged on the outer walls on both sides of the cooling box 2, and rectangular notches 25 for avoiding the cylinder head blanks are arranged on the outer walls on both sides of the cooling box 2, and the transport mechanism 7 is arranged on the cooling box 2 and is used to push the cylinder head blank to move.

[0046] The staff places the cylinder head blank to be cooled on the corresponding conveyor belt 24, and then the conveyor belt 24 drives the cylinder head blank to be cooled to move. When it moves to the rectangular notch 25 of the cooling box 2, the top plane of the supporting plate 3 is parallel to the rectangular notch 25. The multiple groups of cylinder head blanks are pushed to move onto the supporting plate 3 by the conveying mechanism 7. Then, the air supply mechanism 4 delivers gas to the inside of the cooling box 2 and the inside of the water exchange tank 1 through the air supply pipe 23 and the air intake pipe 221 respectively. At this time, the closing component 15 blocks the connecting pipe 12, the opening and closing mechanism 6 opens the air vent 31, and the drain hole 32 is in a blocked state. (As the air supply pipe 23 and the air intake pipe 221 are connected, the air supply pipe 23 and the air intake pipe 221 are connected.) Fig.10The gas can be blown in multiple directions to the cylinder head blank placed on the support plate 3 through the sprinkler head 211 on the cooling pipe 21 and the air holes 31 on the support plate 3, and the first one-way valve 311 is set to increase the ejection speed of the gas from the air holes 31, so as to initially cool the cylinder head blank placed on the support plate 3; then, the support plate 3 moves, the closing assembly 15 opens the connecting pipe 12, and the opening and closing mechanism 6 blocks the air holes 31 and the drain holes 32 (as shown in FIG. Fig.11 As shown), at this time, the gas entering the cooling box 2 can only enter the water change tank 1 through the connecting pipe 12, and the drain pipe 13 and the connecting pipe 12 are located on the same side. At this time, the gas is located between the two adjacent partition plates 111 and the water change tank 1, so that the coolant inside the water change tank 1 can be pushed into the main through pipe 22 through the drain pipe 13 and the connecting hose 14, and in this process, the air supply mechanism 4 is also transporting gas to the main through pipe 22 through the air intake pipe 221, so that the coolant can be mixed with the gas and then sprayed out through the sprinkler nozzle 211, thereby contacting the cylinder head blank on the support plate 3, and performing secondary cooling on the cylinder head blank; the coolant located between the two partition plates 111 completely enters the top of the support plate 3, so that the cylinder head blank can be completely immersed in the coolant, thereby further improving the cooling effect; then, the support plate 3 moves, the closing component 15 opens the connecting pipe 12, and the opening and closing mechanism 6 makes the drain hole 32 in an open state (as shown in FIG. Fig.12 As shown), the coolant on the support plate 3 can return to the inside of the water exchange tank 1 through the drain hole 32 and the connecting pipe 12, which can not only complete the recovery of the coolant, but also enable the coolant to flow, so as to drive the heat on the cylinder head blank more quickly; when the recovery is completed, with the cooperation of the transposition mechanism 5, the mounting column 11 can be rotated to adjust the position of the recovered coolant, so that the new coolant is moved to the drain pipe 13, thereby ensuring the subsequent cooling effect of the cylinder head blank; and in the recovery process, when sending Under the action of the gas mechanism 4, the gas blows the cylinder head blank through the sprinkler nozzle 211, which can not only reduce the residual coolant on its surface, but also cool the cylinder head blank again, further ensuring its cooling effect; when the cooling is completed, the support plate 3 moves upward to the rectangular notch 25, and the cooled cylinder head blank is pushed to the conveyor belt 24 on the other side through the conveying mechanism 7 and the subsequent cylinder head blank to be cooled is pushed onto the support plate 3, so that multiple groups of cylinder head blanks can be cooled continuously, thereby improving the cooling efficiency.

[0047] See also Figures 10 to 12As shown, the opening and closing mechanism 6 includes a sealing plate 61 and a movable screw rod 62; the sealing plate 61 is slidably arranged at the bottom of the supporting plate 3, and a plurality of air supply channels 611 and drainage channels 612 cooperating with the air holes 31 and the drainage holes 32 are arranged on the sealing plate 61; there are two movable screw rods 62, and the two movable screw rods 62 are mirror-imaged and rotatably arranged at the bottom of the supporting plate 3, and the length direction of the movable screw rods 62 is perpendicular to the length direction of the supporting plate 3, and a winding wheel 621 is arranged at one end of each movable screw rod 62 along the length direction, and each winding wheel 621 is connected to the inner wall of the bottom of the cooling box 2 through a traction rope 622, and a first reset torsion spring 623 is arranged on each movable screw rod 62; two synchronization blocks 613 are mirror-imaged at the bottom of the sealing plate 61, and the synchronization blocks 613 are respectively threadedly connected to the corresponding movable screw rods 62.

[0048] In the initial state, the supporting plate 3 is located at the rectangular notch 25, and the traction rope 622 overcomes the torsion of the first reset torsion spring 623 and is in a taut state. At this time, the air supply channel 611 corresponds to the air vent 31 one by one, and the drainage channel 612 and the drainage hole 32 are in a staggered state, so that the gas can only be discharged through the air vent 31; as the supporting plate 3 moves, the distance between the winding wheel 621 and the bottom inner wall of the cooling box 2 is reduced. Under the torsion of the first reset torsion spring 623, the movable screw rod 62 can be rotated, thereby moving the sealing plate 61. At this time, the air supply channel 611 is staggered with the air vent 31, and the drainage channel 612 is staggered with the drainage hole 32. The water holes 32 are still in a staggered state, so that the air holes 31 and the drainage holes 32 are both in a blocked state, so that the coolant can accumulate on the support plate 3, so that the cylinder head blank can be completely covered by the coolant; then, the support plate 3 continues to move, and the drainage channel 612 corresponds to the drainage holes 32 one by one, so that the coolant can enter the cooling box 2 through the drainage holes 32, and return to the water change tank 1 through the connecting pipe 12, thereby completing the recovery of the coolant. After the recovery is completed, the shifting mechanism 5 can rotate the mounting column 11, so that the unused coolant in the water change tank 1 can be utilized, thereby ensuring the cooling effect of the subsequent cylinder head.

[0049] See also Figures 5 to 9As shown, the shifting mechanism 5 includes a lower pressure cylinder 51 and a return spring 52; a rotating rod 112 extending vertically upward and passing through the water exchange tank 1 and the cooling box 2 is arranged on the top of the mounting column 11, and a one-way bearing 113 is arranged at one end of the rotating rod 112 extending into the cooling box 2, and a sliding column 114 is arranged on the outer wall of the one-way bearing 113 in a mirror image, and an arc-shaped guide groove 511 is arranged on the inner wall of the lower pressure cylinder 51 in a mirror image, and the sliding column 114 can be slidably arranged in the corresponding guide groove, and a fixing plate 512 is arranged on the outer wall of the top of the lower pressure cylinder 51 in a mirror image, and each fixing plate 512 is provided with a positioning hole 513, and two fixing rods 26 are arranged on the inner wall of the bottom of the cooling box 2, and the fixing rods 26 can be slidably arranged in the corresponding positioning holes 513, and a limiting disk 261 is arranged on the top of each fixing rod 26, and there are two return springs 52, which are sleeved on the corresponding fixing rods 26 and are located between the corresponding fixing plates 512 and the inner wall of the bottom of the cooling box 2.

[0050] Under the elastic force of the return spring 52, the pressure cylinder 51 can be located away from the bottom inner wall of the cooling box 2. The position of the pressure cylinder 51 can be limited by the setting of the limit plate 261 to prevent it from being ejected by the elastic force of the return spring 52. As the supporting plate 3 moves, when the supporting plate 3 contacts the pressure cylinder 51, the pressure cylinder 51 overcomes the elastic force of the corresponding return spring 52 and moves toward the bottom inner wall of the cooling box 2. At this time, the sliding column 114 on the outer wall of the one-way bearing 113 can move along The corresponding arc-shaped guide groove 511 moves, so that the sliding column 114 can rotate along its axis, so as to adjust the position of the coolant inside the water change tank 1. When the support plate 3 is separated from the lower pressure cylinder 51, the lower pressure cylinder 51 can be reset under the elastic force of the reset spring 52. Under the action of the one-way bearing 113, the rotating rod 112 can be prevented from reversing, so that the mounting column 11 can only rotate along a fixed direction, so that the coolant in the water change tank 1 can be used in turn, ensuring the overall cooling effect.

[0051] See also Figure 1 and Figure 2 As shown, the air supply mechanism 4 includes an air pump 41; the air pump 41 is arranged on the outer wall of one side of the cooling box 2 close to the main through pipe 22, and the output end of the air pump 41 is connected to the air supply pipe 23 and the air intake pipe 221 through the three-way pipe 42 respectively.

[0052] By providing an air pump 41, the air pump 41 can deliver gas to the air supply pipe 23 and the air intake pipe 221 respectively through the three-way pipe 42. During the movement of the support plate 3, the gas can not only blow and cool the cylinder head blank placed thereon, but also push the coolant in the water exchange tank 1, so that the coolant sprays and soaks the cylinder head blank, thereby accelerating the cooling of the cylinder head blank.

[0053] See also Figure 2 and Fig.13 As shown, the closing component 15 includes a flip plate 151; the connecting tube 12 is arranged in a vertical state, and two rotating holes 121 are mirror-imaged on the outer wall of the connecting tube 12, and two rotating shafts 152 are mirror-imaged on the outer wall of the flip plate 151, and the rotating shafts 152 are rotatably arranged in the corresponding rotating holes 121, and the flip plate 151 is located inside the connecting tube 12, and each rotating shaft 152 is provided with a second reset torsion spring 153 at one end extending out of the connecting tube 12; an L-shaped mounting plate 33 is provided at the bottom of the supporting plate 3, and an elastic telescopic rod 34 for pushing the flip plate 151 is provided at the end of the L-shaped mounting plate 33 away from the supporting plate 3, and an intercepting plate 122 is provided at the bottom of the connecting tube 12 for preventing the elastic telescopic rod 34 from extending into the water exchange tank 1.

[0054] Under the torsion of the second reset torsion spring 153, the flip disk 151 can be set in a horizontal state, thereby sealing the inside of the connecting pipe 12. As the supporting plate 3 moves, the elastic telescopic rod 34 arranged on the L-shaped mounting plate 33 can contact the edge of the flip disk 151, so that the flip disk 151 can overcome the torsion corresponding to the second reset torsion spring 153 and rotate, so that the connecting pipe 12 is in an open state, thereby facilitating the gas to push the coolant in the water exchange tank 1, and through the setting of the intercepting plate 122, the moving distance of the elastic telescopic rod 34 can be limited to avoid its influence on the rotation of the partition plate 111.

[0055] See also Figure 1 and Fig.14 As shown, the transport mechanism 7 includes a guide rod 71, a sliding plate 72 and an adjusting screw 73; a vertical plate 241 is provided on the opposite sides of the two conveyor belts 24, the guide rod 71 is horizontally arranged between the two vertical plates 241, there are two sliding plates 72, each of which is provided with a sliding hole 721, the guide rod 71 is slidably arranged in the corresponding sliding hole 721, the adjusting screw 73 is rotatably arranged between the two vertical plates 241, the sliding plate 72 is threadedly connected to the adjusting screw 73, and a strip-shaped groove 722 is provided at the bottom of each sliding plate 72, and a resistance plate 723 is hinged in each strip-shaped groove 722.

[0056] There is a space for placing the cylinder head blank between the two sliding plates 72. An adjusting motor for driving the adjusting screw 73 to rotate is also provided on one of the vertical plates 241. As the adjusting motor rotates, the contact plate 723 can push the cylinder head blank to be cooled to move, so that the cylinder head blank on the corresponding conveyor belt 24 can be moved to the supporting plate 3. At this time, the cylinder head blank is located between the two contact plates 723, so that the gas and liquid sprayed from the sprinkler head 211 can be intercepted and guided, so that the gas can be more The contact plate 723 contacts the cylinder head blank, so that the contact plate 723 rotates to avoid volume collision between the contact plate 723 and the cylinder head blank. Subsequently, the screw rod 73 is adjusted to rotate in the opposite direction so that the cylinder head blank to be cooled can be pushed onto the supporting plate 3. The cylinder head blank that has been cooled can be moved to another conveyor belt 24, thereby realizing continuous cooling of the cylinder head blank.

[0057] See also Figures 10 to 12 As shown, the air supply channel 611 and the drainage channel 612 are both elliptical in shape.

[0058] The air supply channel 611 and the drainage channel 612 are set to be elliptical in shape, so as to increase the blowing time of the gas and the recovery time of the coolant, thereby ensuring the cooling effect of the cylinder head blank and enabling the coolant to be completely recovered.
