At the same time, the output end of the hydraulic cylinder will rise to squeeze the top block. At this time, the valve that has been fixed in the mold will be demoulded by the squeezing force of the top block and separated from the mold, which improves the demoulding efficiency of the device. The pushing force of the hydraulic rod is directly used to make the top block contact with the mold, which reduces the use time of the device and makes the mold that needs to be separated be demoulded more quickly.

When started, the electric telescopic rod 2 will move downward, and the electric telescopic rod 2 will drive the connecting L block to move downward, and the connecting L block will drive the upper mold to move. When the upper mold moves a certain distance, the upper mold will contact and match with the lower mold. The lower pressing circular plate and the upper mold cannot drive the lower pressing circular plate to rotate together through their own gravity when the electric telescopic rod 1 rotates, so there will be relative rotation between the two. At this time, the poured liquid will enter the interior of the mold through the injection hole on the upper mold. , pouring is completed, at this time the motor will start, the output end of the motor will drive the electric telescopic rod to rotate, at this time the electric telescopic rod will rotate and move downward, the electric telescopic rod will drive the downward pressing circular plate to move downward, after moving a certain distance, the spring block will contact the upper mold, at this time the electric telescopic rod will stop moving downward, the rotation of the electric telescopic rod will drive the rotating plate to rotate, during the rotation process the rotating plate will contact the top of the spring block and squeeze the spring block, so that the spring block is squeezed downward to hit the top of the upper mold, which will reduce the bubbles generated inside the mold during pouring, and avoid bubbles inside the mold during pouring and casting that will affect the quality of valve parts, bubbles It will change the flow characteristics of the molten metal, which may lead to insufficient or uneven filling of the mold, affecting the dimensional accuracy and shape accuracy of the parts, thereby reducing the bubbles inside the mold, improving the reliability and service life of the product, and increasing the strength of the casting. At the same time, during the rotation of the rotating plate, the rotating plate will drive the scraper to rotate, and the scraper will rotate and scrape around the injection hole to make the pouring liquid dripping out during pouring leave the surface of the opening, avoiding the cooling and solidification of the pouring liquid due to long-term adhesion near the injection hole, thereby affecting the use of the device, reducing the blockage of the injection hole, and further affecting subsequent use.

[0008] Preferably, the stirring mechanism includes a second support seat, a stirring drum, a rotating plate, a reciprocating screw, a third connecting column, an arc plate, a fixed column, a stirring column, a limit block, and a slot. The second support seat is fixedly connected to the top of the box body, the stirring drum is fixedly connected to the top of the second support seat, the reciprocating screw is rotatably connected to the inner wall of the stirring drum, the rotating plate is fixedly connected to the circumferential surface of the reciprocating screw, the third connecting column is fixedly connected to the circumferential surface of the reciprocating screw, the arc plate is fixedly connected to the circumferential surface of the third connecting column, the fixed column is movably connected to the circumferential surface of the reciprocating screw, the stirring column is fixedly connected to the circumferential surface of the fixed column, and the limit block is fixedly connected to the circumference of the fixed column. The groove is provided on the inner wall of the mixing drum, and the mixing mechanism also includes a rotating column 1, a pushing pressure block, a rotating long block, a rotating long column, and a nozzle. The rotating column 1 is fixedly connected to the circumferential surface of the reciprocating screw rod, the pushing pressure block is fixedly connected to the circumferential surface of the rotating column 1, the rotating long column is rotatably connected to the inner wall of the mixing drum through a torsion spring, the rotating long block is fixedly connected to the circumferential surface of the rotating long column, the nozzle is fixedly connected to the circumferential surface of the rotating long column, the limit block is slidably connected to the inner wall of the mixing drum, the arc plate contacts the inner wall of the mixing drum, the pushing pressure block contacts the rotating long block, the nozzle and the rotating long column are connected to each other, and at the same time, on the electric telescopic rod 2 During the downward movement, the electric telescopic rod 2 drives the up and down movement. During the movement, the L plate will contact and squeeze the rotating plate to make it rotate, and the rotating plate drives the reciprocating screw to rotate. The rotation of the reciprocating screw drives the connecting column 3 to rotate, and the connecting column 3 drives the arc plate to rotate. At the same time, the rotation of the reciprocating screw will drive the fixed column to rotate and move, but the limit block slides on the inner wall of the slot. At this time, the stirring column and the fixed column can only move back and forth through the reciprocating groove on the reciprocating screw, which can stir the release agent inside the mixing drum, make the release agent fully integrated, and improve the use effect of the release agent. The scraping of the arc plate can make the release agent adhered to the inner walls of both sides of the mixing drum fall off to avoid demolding. The agent stays on the inner wall of the mixing drum for a long time, which increases the difficulty of cleaning the mixing drum. When the reciprocating screw rotates, the reciprocating screw will drive the rotating column to rotate, and the rotating column will drive the push block to rotate. In the process of pushing the block to rotate, the push block will contact the rotating long block and push the rotating long block. The rotating long block will drive the rotating long column to rotate. The rotating long column drives the nozzle to rotate the angle, so that when the upper mold is opened, the release agent can be sprayed at different angles on the surface of the valve parts after casting, making it more convenient and easy to demold the parts. The use of release agent can reduce defects on the surface of the casting, such as scratches and dents, thereby improving the appearance and quality of the final product.

[0009] A method for using a casting production device for valve casting comprises the following steps: Step 1: When the device is started, the motor will start to drive the electric telescopic rod to rotate and rise, so that the lower mold is separated from the upper mold, and at the same time the output end of the hydraulic cylinder will rise to squeeze the top block; Step 2: When the output end of the hydraulic cylinder rises, the output end of the hydraulic cylinder drives the connecting column 1 to rise, the connecting column 1 drives the connecting rod to rise, the connecting rod drives the connecting column 2 to move, and the connecting column 2 drives the hinge block 1 to rise; Step 3: The hinge block 1 drives the push rod to move, and the push rod slides horizontally on the inner wall of the box body. The push rod drives the hinge block 2 to move, and the hinge block 2 drives the push plate to move. However, the push plate is limited by the sliding groove plate and can only move horizontally through the inner wall of the sliding groove plate. Step 4: The push rod is hinged on the circumferential surface of hinge block 2 through a torsion spring, and the other end of the push rod is also hinged on the circumferential surface of hinge block 1 through a torsion spring. At this time, during the rising process of connecting column 2, the push rod will push hinge block 2 to move, and hinge block 2 will drive the push plate to move. The push rod will change its angle during the rising process to enable the push plate to slide along the inner wall of the sliding groove plate.

The bubbles will change the flow characteristics of the molten metal, which may cause insufficient or uneven filling of the mold, affecting the dimensional accuracy and shape accuracy of the parts, thereby reducing the bubbles inside the mold, improving the reliability and service life of the product, and improving the strength of the casting.

[0020] A method for using a casting production device for valve casting comprises the following steps: Step 1: When the device is started, the motor 3 will start to drive the electric telescopic rod 4 to rotate and rise, so that the lower mold 510 is separated from the upper mold 605, and at the same time the output end of the hydraulic cylinder 8 will rise to squeeze the top block 509; Step 2: When the output end of the hydraulic cylinder 8 rises, the output end of the hydraulic cylinder 8 drives the connecting column 1 501 to rise, the connecting column 1 501 drives the connecting rod 502 to rise, the connecting rod 502 drives the connecting column 2 503 to move, and the connecting column 2 503 drives the hinge block 1 504 to rise; Step 3: The hinge block 1 504 drives the push rod 505 to move, and the push rod 505 slides horizontally on the inner wall of the box body 1, and the push rod 505 drives the hinge block 2 506 to move, and the hinge block 2 506 drives the push plate 508 to move, but the push plate 508 is limited by the sliding groove plate 507 and can only move horizontally through the inner wall of the sliding groove plate 507; Step 4: The push rod 505 is hinged on the circumferential surface of the hinge block 2 506 through a torsion spring, and the other end of the push rod 505 is also hinged on the circumferential surface of the hinge block 1 504 through a torsion spring. At this time, during the rising process of the connecting column 2 503, the push rod 505 will push the hinge block 2 506 to move, and the hinge block 2 506 will drive the push plate 508 to move. The push rod 505 will change its angle during the rising process to enable the push plate 508 to slide with the inner wall of the sliding groove plate 507.

[0021] Working principle: When starting, the electric telescopic rod 601 will move down, the electric telescopic rod 601 will drive the connection L block 603 to move down, and the connection L block 603 will drive the upper mold 605 to move. When the upper mold 605 moves a certain distance, the upper mold 605 will contact and fit with the lower mold 510. The lower pressing circular plate 604 and the upper mold 605 will not be able to drive the lower pressing circular plate 604 to rotate together due to their own gravity. Therefore, there will be relative rotation between the two. At this time, the poured The liquid enters the interior of the mold through the injection hole 610 on the upper mold 605 to complete the pouring. At this time, the motor 3 will start, and the output end of the motor 3 will drive the electric telescopic rod 4 to rotate. At this time, the electric telescopic rod 4 will rotate and move downward, and the electric telescopic rod 4 will drive the downward pressing circular plate 604 to move downward. After moving a certain distance, the spring block 607 will contact the upper mold 605. At this time, the electric telescopic rod 4 stops moving downward, and the rotation of the electric telescopic rod 4 drives the rotating plate 608 to rotate. The rotating plate 60 During the rotation, the top of the spring block 607 will be contacted and squeezed, so that the spring block 607 is squeezed downward to hit the top of the upper mold 605, which will reduce the bubbles generated inside the mold during pouring, and avoid the bubbles inside the mold affecting the quality of the valve parts during pouring and casting. The bubbles will change the flow characteristics of the molten metal, which may cause insufficient or uneven filling of the mold, affecting the dimensional accuracy and shape accuracy of the parts. Reducing the bubbles inside the mold can improve the reliability and service life of the product and improve the strength of the casting. At the same time, during the rotation of the rotating plate 608, the rotating plate 608 will drive the scraper 609 to rotate, and the scraper 609 will rotate around the injection hole 610 to scrape away the pouring liquid dripping out during pouring, so that the pouring liquid is prevented from cooling and solidifying due to long-term adhesion near the injection hole 610, thereby affecting the use of the device, reducing the blockage of the injection hole 610, and further affecting the subsequent use.

[0022] At the same time, in the process of the electric telescopic rod 2 601 moving up and down, the electric telescopic rod 2 601 drives the L plate 602 to move up and down. In the process of moving, the L plate 602 will contact and squeeze the rotating plate 703 to make the rotating plate 703 rotate, and the rotating plate 703 drives the reciprocating screw rod 704 to rotate. The rotation of the reciprocating screw rod 704 drives the connecting column three 705 to rotate, and the connecting column three 705 drives the arc plate 706 to rotate. At the same time, the rotation of the reciprocating screw rod 704 will drive the fixed column 707 to rotate and move, but the limit block 709 slides on the inner wall of the slot 710. At this time, the stirring column 708 and the fixed column 707 can only perform reciprocating transverse movement through the reciprocating groove on the reciprocating screw rod 704, which can stir the release agent inside the stirring drum 702, make the release agent fully integrated, and improve the use effect of the release agent. The scraping of the arc plate 706 can make the two sides of the stirring drum 702 The release agent adhered to the inner wall of the side falls off, so as to prevent the release agent from stagnating on the inner wall of the mixing drum 702 for a long time, thereby increasing the difficulty of cleaning the mixing drum 702. When the reciprocating screw 704 rotates, the reciprocating screw 704 will drive the rotating column 711 to rotate, and the rotating column 711 will drive the pushing block 712 to rotate. In the process of pushing the pressing block 712 to rotate, the pushing pressing block 712 will contact the rotating long block 713 and push the rotating long block 713. The rotating long block 713 will drive the rotating long column 714 to rotate. The rotating long column 714 drives the nozzle 715 to rotate at an angle, so that when the upper mold 605 is opened, the release agent can be sprayed at different angles on the surface of the valve parts after casting, making it more convenient and easy to demold the parts. The use of the release agent can reduce defects on the surface of the casting, such as scratches and dents, thereby improving the appearance and quality of the final product.
