The two ducts 504 are located between the lower mold 403 and the upper mold 408. ;

[0043] The use steps of the present invention are as follows: when casting the water pump housing of an automobile engine, the operation of the first motor 110 can drive the first gear 112 to rotate accordingly. When the first gear 112 rotates, it can drive the turntable 401 to rotate accordingly by meshing with the gear ring 402. When the turntable 401 rotates, it can drive multiple groups of molds to switch positions in a circular rotation state. After one group of lower molds 403 and upper molds 408 are moved to the position below the pressure plate 303, the second motor 205 is started to drive the support shaft 202 to rotate accordingly. The rotation of the support shaft 202 drives the furnace 203 to rotate accordingly. After the furnace 203 tilts and rotates toward the casting bucket 418, the aluminum liquid will flow into the casting bucket 418 through the casting port 204. , the aluminum liquid will flow into the cylinder 412 along the side pipe 417, and the hydraulic cylinder 302 can drive the pressure plate 303 to move downward after it is operated. After the pressure plate 303 moves downward, it fits with the connecting plate 414 and can push the connecting plate 414 to move downward. After being pushed by the force, the connecting plate 414 can drive the push plate 416 to move downward through the connection of the push rod 415. At this time, the push plate 416 moves downward to generate pressure, and the aluminum liquid is quickly pressed into the cavity between the lower mold 403 and the upper mold 408. The aluminum liquid is in the cavity and quickly solidifies and forms under high pressure, that is, the casting process of the automobile engine water pump housing is completed. After the casting of a set of molds is completed, the first motor 110 continues to operate, and the roller 411 will move upward along the upward inclined surface of the guide seat 108. The roller 411 can pass through the support 41 0 and the side frame 409 drive the upper mold 408 to move up with it. After the upper mold 408 moves up, it is separated from the lower mold 403. The setting of the guide rod 407 plays a supporting and limiting role for the upper mold 408. With the continuous operation of the first motor 110, the mold continues to move to the supply rack 201 and the bracket 301 for die-casting. The lower mold 403 and the upper mold 408 that have completed the die-casting will rotate with the turntable 401. After the demoulding is completed at the tooth plate 109 position, it will subsequently pass through the positions of multiple cooling components 5 to complete efficient heat dissipation of the lower mold 403, the upper mold 408 and the water pump housing. With the continuous operation of the turntable 401, the lower mold 403 and the upper mold 408 will move to a position close to the side plate 106. By using the robot arm 107, after the vacuum suction cup is connected to the output end of the robot arm 107, the processed automobile engine water pump housing can be automatically taken out from the lower mold 403. The lower mold 403 and the upper mold 408 that have completed the workpiece removal continue to move to the supply rack 201 and the bracket 301 position after the next start-up stroke of the first motor 110. The lower mold 403 and the upper mold 408 are continued to be die-cast through the coordinated use of the supply component 2 and the die-casting component 3. By arranging multiple groups of molds above the turntable 401, the first motor 110, the furnace 203, the second motor 205, the hydraulic cylinder 302, the first fan 503 and the second fan 505 can be used to realize the sequential processing of multiple groups of molds.

[0044] Embodiment 2: Figure 3 , Figure 4 and Fig.10 As shown, the number of lower molds 403 and upper molds 408 is the same, and sliding rods 404 are fixedly connected at the bottom corners of the lower mold 403. The sliding rods 404 slide through and extend to the lower side with the turntable 401. A bottom plate 405 is fixedly connected between the lower end surfaces of the plurality of sliding rods 404. A tooth block 406 is fixedly connected to the bottom of the bottom plate 405. A tooth plate 109 is fixedly connected to the top of the support plate 102. The positions of the tooth plate 109 and the tooth block 406 match each other. A rubber pad is fixedly connected to the bottom of the lower mold 403, and the rubber pad is located on the inner side of the sliding rod 404.

[0045] The use steps of the present invention are as follows: in the process of moving the lower mold 403 and the upper mold 408 that have completed casting to the next stroke position through the operation of the first motor 110, the lower mold 403 that has completed casting will pass through the position of the tooth plate 109 during the displacement process. When the tooth block 406 is displaced to the position of the tooth plate 109, the tooth block 406 will contact the inclined surface of the tooth plate 109 surface. At this time, the tooth block 406 can be slightly lifted up. As the lower mold 403 continues to displace, the tooth block 406 repeatedly contacts the inclined surface of the tooth plate 109 surface. The lower mold 403 will maintain a high frequency and repeatedly maintain a small amplitude of being lifted up and dropped. The lower mold 403 is repeatedly displaced up and down, so that the lower mold 403 vibrates. Under the action of the vibration force, the formed water pump housing can be separated from the lower mold 403, that is, through the coordinated use of the slide bar 404, the bottom plate 405, the tooth block 406 and the tooth plate 109, the purpose of automatic demoulding during the operation of the device is achieved, and the degree of automation of the device is improved.

[0046] Embodiment 3: Figure 3 and Fig.11 As shown, a mounting plate 502 is fixedly connected to the top of the fixing frame 501, a first fan 503 is symmetrically fixedly connected to the inner surface of the mounting plate 502, an air duct 504 is symmetrically fixedly connected to the outer surface of the mounting plate 502, a plurality of second fans 505 are fixedly connected to the inner surface of the air duct 504, the air duct 504 is in a connected state with the mounting plate 502, and the two air ducts 504 are located between the lower mold 403 and the upper mold 408.

[0047] The use steps of the present invention are as follows: the first fan 503 and the second fan 505 are started in coordination to cool down the lower mold 403 and the upper mold 408; through the setting of two air ducts 504, the two second fans 505 are operated to suck air, and the air sucked in from the upper and lower sides can be discharged from the mounting plate 502. Therefore, through the use of the two air ducts 504, the surfaces of the lower mold 403 and the upper mold 408 can be respectively faced to absorb air and dissipate heat; the hot air entering the air duct 504 will be discharged from the mounting plate 502 through the operation of the first fan 503, thereby achieving the purpose of cooling down the lower mold 403 and the upper mold 408; through the use of the cooling component 5, the lower mold 403 and the upper mold 408 can be separated, and then the surfaces of the lower mold 403 and the upper mold 408 can be simultaneously faced to exhaust air and dissipate heat, which has a good heat dissipation effect on the mold and a high heat dissipation efficiency.

[0048] The effect and working principle of the whole mechanism are as follows: when casting the water pump housing of the automobile engine, the multiple sets of molds can be die-casted in sequence by using multiple sets of lower molds 403 and upper molds 408. When starting the processing, the operation of the first motor 110 can drive the first shaft 111 to rotate, and the rotation of the first shaft 111 can drive the first gear 112 to rotate. When the first gear 112 rotates, it can drive the turntable 401 to rotate by meshing with the gear ring 402. The turntable 401 slides in the slide rail 103 through the connection of the extension rod 105 and the pulley 104. When the turntable 401 rotates, it can drive multiple sets of molds to switch positions in a circular rotation state. In one set of lower molds 403, the upper mold 408 is rotated. After the upper mold 408 and the upper mold 403 are moved to the position below the pressure plate 303, the aluminum is heated in the furnace 203 to become molten aluminum. At this time, the casting port 204 is above the casting bucket 418. When casting begins, the second motor 205 is controlled to start in coordination with the hydraulic cylinder 302. After the second motor 205 is started, the second rotating shaft 206 can be driven to rotate accordingly. The rotation of the second rotating shaft 206 can drive the second gear 207 to rotate accordingly. The second gear 207 can drive the support shaft 202 to rotate accordingly by meshing with the third gear 208. At this time, the rotation of the support shaft 202 drives the furnace 203 to rotate accordingly. After the furnace 203 tilts and rotates toward the casting bucket 418, the molten aluminum will flow into the casting bucket 418 through the casting port 204. The machine 205 operates to control the melting furnace 203 to reset to the initial position, and the aluminum liquid will flow into the cylinder 412 along the side pipe 417. At this time, the hydraulic cylinder 302 operates. After the hydraulic cylinder 302 operates, it can drive the pressure plate 303 to move downward. After the pressure plate 303 moves downward, it fits with the connecting plate 414 and can push the connecting plate 414 to move downward. After being pushed by the force, the connecting plate 414 can drive the push plate 416 to move downward through the connection of the push rod 415. At this time, the push plate 416 moves downward to generate pressure, and the aluminum liquid is quickly pressed into the cavity between the lower mold 403 and the upper mold 408. The aluminum liquid is in the cavity and quickly solidifies and forms under high pressure, that is, the casting process of the automobile engine water pump housing is completed. After completing the casting of a set of molds, the first motor 110 is started to continue to run. At this time, the turntable 40 The rotation drives the group of molds to rotate toward the fixed frame 501. When the upper mold 408 rotates with the turntable 401, the upper mold 408 drives the side frame 409, the support 410 and the roller 411 to move. The roller 411 contacts the guide seat 108 during the circumferential displacement. At this time, the roller 411 moves upward along the upward slope of the guide seat 108. The roller 411 can drive the upper mold 408 to move upward through the connection between the support 410 and the side frame 409. After the upper mold 408 moves upward, it is separated from the lower mold 403. At this time, the automobile engine water pump housing that has been die-cast will stay in the lower mold 403. When the upper mold 408 moves upward, the setting of the guide rod 407 plays a role in supporting and limiting the upper mold 408.Ensure that the upper mold 408 and the lower mold 403 always maintain a corresponding position state up and down. After the upper mold 408 moves up, there will be a large gap between it and the lower mold 403, and the height of the air duct 504 and the mounting plate 502 corresponds to the spacing position between the upper mold 408 and the lower mold 403. With the operation of the first motor 110, the next group of molds will move to the supply rack 201 and the bracket 301. At this time, the first motor 110 stops running, and the second motor 205 and the hydraulic cylinder 302 cooperate to operate to cast the next group of molds. At this time, the lower mold 403 and the upper mold 408 that have completed casting and separation are located between the two air ducts 504. The first fan 503 and the second fan 505 are started to cast the lower mold 403 and the upper mold 4 08 for cooling. By setting two air ducts 504, two second fans 505 are operated to suck air. The air sucked in from the upper and lower sides can be discharged from the mounting plate 502. Therefore, by using the two air ducts 504, the surfaces of the lower mold 403 and the upper mold 408 can be respectively faced to absorb air and dissipate heat. The hot air entering the air duct 504 will be discharged from the mounting plate 502 through the operation of the first fan 503, so as to achieve the purpose of cooling the lower mold 403 and the upper mold 408. By using the cooling component 5, the lower mold 403 and the upper mold 408 can be separated, and then the surfaces of the lower mold 403 and the upper mold 408 can be simultaneously faced to exhaust air and dissipate heat, which has a good heat dissipation effect on the mold. The efficiency is high. In the process of moving the lower mold 403 and the upper mold 408 that have completed casting to the next stroke position through the operation of the first motor 110, the lower mold 403 that has completed casting will pass through the position of the tooth plate 109 during the displacement process. The surface shape of the tooth plate 109 is a small inclined block with an inclined surface facing the side of the lower mold 403. When the lower mold 403 rotates, the tooth block 406 can be driven to follow the movement through the connection between the slide bar 404 and the bottom plate 405. The bottom of the tooth block 406 is at the same height as the plane of the tooth plate 109. When the tooth block 406 is displaced to the position of the tooth plate 109, the tooth block 406 will contact the inclined surface of the tooth plate 109 surface. At this time, the tooth block 406 can be slightly lifted up, that is, through the connection between the tooth block 406, the bottom plate 405 and the slide bar 404 The lower mold 403 can be driven to move slightly upward, and then the tooth block 406 passes one of the inclined positions, and the other side of the inclined surface is a straight surface. At this time, the tooth block 406 moves through the inclined position and loses the support of the jacking state, so the tooth block 406 will fall to the state of fitting the plane of the tooth plate 109. With the continuous displacement of the lower mold 403, the tooth block 406 repeatedly contacts the inclined surface of the tooth plate 109 surface, and the lower mold 403 will maintain a high frequency and repeatedly maintain a small amplitude of being jacked up and falling. When the lower mold 403 falls and contacts the surface of the turntable 401, the setting of the rubber pad can reduce the impact force on the lower mold 403 when it falls. The lower mold 403 is repeatedly displaced up and down, causing the lower mold 403 to vibrate. Under the action of the vibration force,The formed water pump shell can be separated from the lower mold 403, that is, through the coordinated use of the sliding rod 404, the bottom plate 405, the tooth block 406 and the tooth plate 109, the purpose of automatic demoulding during the operation of the device is achieved, and the degree of automation of the device is improved. With the continuous operation of the first motor 110, the mold continues to move to the supply rack 201 and the bracket 301 position for die-casting. The lower mold 403 and the upper mold 408 that have completed the die-casting process will rotate with the turntable 401. After the demoulding is completed at the tooth plate 109 position, it will subsequently pass through the positions of multiple cooling components 5 to complete efficient heat dissipation of the lower mold 403, the upper mold 408 and the water pump shell. With the continued operation of the turntable 401, the lower mold 403 and the upper mold 408 will move to a position close to the side plate 106. Through the use of the mechanical arm 107, after the vacuum suction cup is connected to the output end of the mechanical arm 107, it can be automatically removed from the lower mold 403. The finished automobile engine water pump housing is taken out, and the lower mold 403 and the upper mold 408 that have completed the workpiece removal continue to move to the supply rack 201 and the bracket 301 position after the next start stroke of the first motor 110. The lower mold 403 and the upper mold 408 are continued to be die-cast through the cooperation of the supply component 2 and the die-casting component 3. By setting multiple sets of molds above the turntable 401, the first motor 110, the furnace 203, the second motor 205, the hydraulic cylinder 302, the first fan 503 and the second fan 505 can be used to realize the sequential processing of multiple sets of molds. The furnace 203 can work continuously, and a single furnace 203 can be simultaneously adapted to multiple sets of molds for casting at a fixed position, ensuring the stable supply of aluminum liquid under the automatic operation state, effectively avoiding the safety risks of manual handling of aluminum liquid, and improving the safety of engine water pump housing casting.
