A casting device for making automobile body metal parts using new materials

Abstract

The present invention discloses a casting device for making automobile body metal parts using new materials, which belongs to the field of automobile parts manufacturing technology and includes a main body device, wherein a fixed mold is fixedly installed on the bottom surface of the main body device, and a movable mold capable of moving up and down is connected to the position corresponding to the fixed mold in the upper part of the main body device through a hydraulic telescopic rod, and an auxiliary groove is provided on the bottom of the fixed mold. When the present invention is used, the collision ball collides with the L-shaped paddle, causing the L-shaped paddle to vibrate, and the vibration prompts the liquid molecules and bubbles in the molten metal inside the fixed mold to produce high-frequency reciprocating motion, causing the bubbles to collide and aggregate due to the difference in movement speed, and small bubbles aggregate into large bubbles and float up and are discharged due to the increase in buoyancy. This solves the problem that during the casting process of the existing automobile body metal parts casting device, due to the lack of an effective auxiliary exhaust structure, the bubbles in the molten metal cannot be fully discharged, resulting in defects such as hollowing and bulging in the molded workpiece, affecting the product quality and pass rate.

Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, in particular to a casting device for manufacturing automobile body metal parts using new materials. Background Art

[0002] In the automotive manufacturing industry, the casting quality of metal parts directly impacts a vehicle's safety, durability, and appearance. Casting equipment that utilizes new materials to produce metal parts is critical for ensuring high-quality production. During the casting process, ensuring the adequate removal of gases from the molten metal to avoid defects such as hollowing and bulging in the finished part is crucial for improving product quality.

[0003] At present, the existing casting devices for automobile body metal parts are insufficient in discharging gas from the molten metal. Most traditional casting devices lack an effective exhaust auxiliary structure and rely solely on the molten metal itself to stand still or simply shake to discharge gas. This is because the mold structure design is relatively simple and no linkage mechanism is set specifically for gas discharge. After the molten metal is injected into the mold, due to the lack of vibration driven by external force, the bubbles in the molten metal cannot be quickly aggregated and discharged. Small bubbles find it difficult to collide with each other to form large bubbles, resulting in a large number of small bubbles remaining inside the molten metal, and ultimately forming hollows, bulges and other problems after the workpiece is formed. These defects not only affect the appearance quality of automobile body metal parts, but also reduce the structural strength and stability of the workpiece, seriously affecting the overall performance and service life of the car. At the same time, workpieces with such quality problems need to be reworked or scrapped, which increases production costs and reduces production efficiency. Therefore, the present invention provides a casting device for automobile body metal parts using new materials to solve the above-mentioned problems. Summary of the Invention

[0009] As a further solution of the present invention, the six L-shaped paddles are all L-shaped blocks, and the cross-sections of the horizontal ends of the six L-shaped paddles close to the connecting column are all conical, and the distances between the ends of the six L-shaped paddles close to each other and the connecting column are the same, the distances between the vertical ends of the six L-shaped paddles and the connection points with the top surface inside the auxiliary groove and the connecting column are all different, and the horizontal ends of the six L-shaped paddles are highly staggered, and the distances between the ends of the six L-shaped paddles close to each other and the wall surface of the side of the arc plate away from the connecting column are smaller than the diameter of the collision ball.

[0010] As a further solution of the present invention, the upper ends of the vertical ends of the two L-shaped linkage rods are fixedly connected with a clamping block, and the clamping block is composed of a diamond block and a rectangular block. The diamond block on the clamping block is fixedly connected to the upper wall surface of the rectangular block on the clamping block. The clamping block is an elastic block, and a sleeve hole is opened at the position corresponding to the clamping block on the extrusion block. The internal length of the sleeve hole is smaller than the maximum diameter of the diamond block on the clamping block, and the internal length of the sleeve hole is larger than the length of the rectangular block on the clamping block.

[0011] As a further solution of the present invention, the ejection mechanism includes a U-shaped lifting block, a lifting column and an air pump, and two second movable holes are symmetrically provided on the left and right side walls of the auxiliary groove, and the inside of the two second movable holes are movably connected with a U-shaped lifting block that can move up and down, and the two ends of the U-shaped lifting block extend to the inside of the auxiliary groove and the outside of the fixed mold respectively. The upper wall surface of the U-shaped lifting block at one end of the auxiliary groove is provided with two rotatable lifting columns through bearings, and the two lifting columns correspond to the positions of the two sealing blocks on the same side up and down, and a connecting hole is provided on the inner bottom surface of the embedded groove, and the upper end of the lifting column extends to the inside of the corresponding connecting hole, and the upper end of the lifting column is fixedly connected to the lower wall surface of the corresponding sealing block, and the positions of the two U-shaped lifting blocks on the outside of the main device corresponding to the two U-shaped lifting blocks are fixedly installed with air pumps through the mounting plate, and the upper output end of the air pump is fixedly connected to the lower wall surface of the corresponding U-shaped lifting block.

[0012] As a further solution of the present invention, an auxiliary slide groove is provided on the outer wall surface of the top column, and the auxiliary slide groove is a spiral groove. An auxiliary slider is fixedly installed on the inner wall surface of the connecting hole at the position corresponding to the auxiliary slide groove, and the auxiliary slider is movably clamped in the inside of the corresponding auxiliary slide groove.

[0013] As a further solution of the present invention, two T-shaped slots are symmetrically provided on the inner wall of the second movable hole, and two T-shaped sliders are fixedly connected to the outer wall of the U-shaped lifting block at positions corresponding to the two T-shaped slots, and the T-shaped sliders are movably clamped in the inside of the corresponding T-shaped slots.

[0014] As a further solution of the present invention, a sealing ring is fixedly connected to the upper wall surface of the fixed mold to improve the sealing performance after the fixed mold and the movable mold are closed.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the movable mold moves downward during use of the present invention, the extrusion block squeezes the L-shaped linkage rod, driving the second connecting ring to drag the first connecting ring downward on the connecting column and rotate, thereby causing the connecting rod to drive the arc plate and the collision ball to perform circular motion with the connecting column as the center. During the motion, the collision ball collides and contacts with the L-shaped paddle, causing the L-shaped paddle to vibrate. This vibration prompts the liquid molecules and bubbles in the molten metal inside the fixed mold to produce high-frequency reciprocating motion, causing the bubbles to collide and aggregate due to the difference in motion speed. After the small bubbles aggregate into large bubbles, they float up and are discharged due to the increased buoyancy. This solves the problem that during the casting process of existing automobile body metal parts casting devices, due to the lack of an effective auxiliary exhaust structure, the bubbles in the molten metal cannot be fully discharged, resulting in defects such as hollowing and bulging in the molded workpiece, affecting product quality and pass rate.

[0017] 2. The present invention is equipped with an ejection mechanism consisting of an air pump, a U-shaped lifting block, a ejector column, a sealing block, an auxiliary slider and an auxiliary slide groove. At the same time, the special size design of the sleeve hole and the clamping block is utilized. When the movable mold and the fixed mold are separated, the extrusion block can drive the L-shaped linkage rod to move upward and reset. During this process, the collision ball hits the L-shaped pick again to achieve auxiliary demolding.

[0018] 3. When the ejection mechanism of the present invention is in operation, the air pump drives the U-shaped lifting block upward within the second movable hole. The U-shaped lifting block drives the ejector column upward to lift the sealing block. Due to the cooperation between the auxiliary slider and the auxiliary chute, the ejector column rotates during the upward movement, driving the sealing block to rotate, thereby quickly separating the sealing block from the molded workpiece inside the fixed mold. This solves the problems of the existing casting device, such as the complex and inefficient demolding process, the proneness of workpiece deformation and damage due to uneven force during demolding, and the difficulty in ensuring the integrity of the demolding process. It effectively improves production efficiency and reduces workpiece loss.

[0019] 4. When the present invention is used, six L-shaped picks are distributed in a circular array on the top surface of the auxiliary groove. The cross-section of the horizontal end close to the connecting column is conical, and the distances between the vertical ends and the connection points of the top surface of the auxiliary groove and the connecting column are different. The horizontal ends are highly staggered. During the movement, the collision ball collides and contacts with the L-shaped picks. The conical structure of the horizontal end of the L-shaped pick can produce a stronger vibration effect during the collision, and due to its special distribution arrangement, the contact range with the fixed mold is expanded, which can generate effective vibration for the molten metal at different positions inside the fixed mold.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 7In an embodiment of the present invention, a casting device for making automobile body metal parts using new materials includes a main device 1, a fixed mold 2 is fixedly installed on the bottom surface of the main device 1, and a movable mold 3 that can move up and down is connected to the position corresponding to the fixed mold 2 on the upper part of the main device 1 through a hydraulic telescopic rod. When in use, the molten metal required for casting is first injected into the interior of the fixed mold 2, and then the hydraulic telescopic rod on the movable mold 3 is activated to drive the movable mold 3 to move downward until the movable mold 3 and the fixed mold 2 are closed together. When casting is completed, the movable mold 3 is reset by the hydraulic telescopic rod, and the staff can demold the workpiece inside the fixed mold 2. The bottom of the fixed mold 2 is provided with an auxiliary groove 4. The auxiliary groove 4 is fixedly connected to a connecting column 5 at the center point of the internal top surface, and a limit plate 19 is fixedly connected to the lower wall surface of the connecting column 5. An auxiliary vibration mechanism for assisting in removing gas from the molten metal is provided on the connecting column 5. Four embedded grooves 20 are symmetrically provided inside the fixed mold 2. The insides of the four embedded grooves 20 are all movably connected with sealing blocks 21. The outer wall surface of the sealing block 21 fits tightly with the inner wall surface of the embedded groove 20, thereby ensuring the integrity of the workpiece when the casting of the equipment is completed. An ejection mechanism for assisting in ejecting the forming mold is provided inside the auxiliary groove 4. The outer wall surface of the movable mold 3 is symmetrically fixedly connected with two extrusion blocks 16 that can drive the auxiliary vibration mechanism to operate by extrusion.

[0030] The auxiliary vibration mechanism includes a first connecting ring 7, an arc-shaped embedded block 8, a connecting rod 9, an arc plate 10 and a collision ball 11. A spiral guide groove 6 is provided on the connecting column 5, and the first connecting ring 7 is movably sleeved on the connecting column 5, and the inner wall surface of the first connecting ring 7 is fixedly connected with the arc-shaped embedded block 8. The arc-shaped embedded block 8 is an arc-shaped block, and the shape and size of the arc-shaped embedded block 8 are adapted to the shape and size of the inside of the spiral guide groove 6. The arc-shaped embedded block 8 is movably clamped in the inside of the spiral guide groove 6. Since the arc-shaped embedded block 8 is located inside the spiral guide groove 6, when the first connecting ring 7 moves on the connecting column 5, the first connecting ring 7 will rotate under the influence of the arc-shaped embedded block 8. The outer wall surface of the first connecting ring 7 is fixedly connected with the connecting rod 9, which is an elastic block. The end of the connecting rod 9 away from the first connecting ring 7 is fixedly connected with the arc plate 10, and the side wall of the arc plate 10 away from the connecting rod 9 is fixedly connected with the collision ball 11.

[0031] The auxiliary vibration mechanism also includes a second connecting ring 12, an L-shaped linkage rod 13 and an L-shaped paddle 18. The second connecting ring 12 is movably sleeved on the connecting column 5 below the first connecting ring 7. The upper wall of the second connecting ring 12 is movably connected to the lower wall of the first connecting ring 7 through a bearing. Therefore, when the first connecting ring 7 rotates on the spiral guide groove 6, the second connecting ring 12 can remain in a non-rotating state. The outer wall surface of the second connecting ring 12 is symmetrically fixedly connected with two L-shaped linkage rods 13. Two first movable holes 15 are provided on the outer wall surface of the fixed mold 2 at positions corresponding to the two L-shaped linkage rods 13. The L-shaped linkage rod 13 passes through the interior of the corresponding first movable holes 15 and extends to the outside of the fixed mold 2. The horizontal plane heights of the tops of the vertical ends are higher than the horizontal plane heights of the upper walls of the fixed mold 2, and the vertical ends of the two L-shaped linkage rods 13 correspond to the two extrusion blocks 16 on the movable mold 3 up and down. Therefore, when the extrusion blocks 16 move downward with the movable mold 3, the extrusion blocks 16 will contact the tops of the vertical ends of the corresponding L-shaped linkage rods 13 and squeeze the corresponding L-shaped linkage rods 13 downward. When the L-shaped linkage rods 13 are squeezed downward by the extrusion blocks 16, the second connecting ring 12 will drag the first connecting ring 7 to move downward on the connecting column 5. At this time, the first connecting ring 7 will rotate under the action of the arc-shaped embedded block 8, and the inner top surface of the auxiliary groove 4 is connected with six L-shaped paddles 18 in a circular array with the center point of the inner top surface of the auxiliary groove 4 as the center.

[0032] By setting a limiting plate 19 on the lower wall of the connecting column 5, the position of the second connecting ring 12 can be limited during use, thereby preventing it from separating from the connecting column 5 under the extrusion of the movable mold 3. The limiting plate 19 plays a limiting role on the second connecting ring 12 to ensure the normal operation of the equipment.

[0033] The six L-shaped paddles 18 are all L-shaped blocks. The cross-sections of the horizontal ends of the six L-shaped paddles 18 close to the connecting column 5 are all conical, and the distances between the ends of the six L-shaped paddles 18 close to each other and the connecting column 5 are the same. The distances between the vertical ends of the six L-shaped paddles 18 and the connection points with the top surface inside the auxiliary groove 4 and the connecting column 5 are all different, and the horizontal ends of the six L-shaped paddles 18 are highly staggered. The distance between the ends of the six L-shaped paddles 18 close to each other and the wall surface of the side of the arc plate 10 away from the connecting column 5 is smaller than the diameter of the collision ball 11, as shown in the spiral guide groove 6.

[0034] When in use, first inject the molten metal required for casting into the interior of the fixed mold 2, then start the hydraulic telescopic rod on the movable mold 3 to drive the movable mold 3 to move downward, at this time the extrusion block 16 on the movable mold 3 will first contact the corresponding L-shaped linkage rod 13, and as the movable mold 3 continues to fall, the extrusion block 16 will squeeze the L-shaped linkage rod 13 to move downward, causing the second connecting ring 12 to drag the first connecting ring 7 to move downward on the connecting column 5, at this time the first connecting ring 7 will rotate under the action of the arc embedded block 8, so the connecting rod 9 will drive the arc plate 10 and the collision ball 11 to do a circular motion with the connecting column 5 as the center, during this period, when the arc plate 10 passes through a certain L-shaped paddle 18, since the distance between the end of the six L-shaped paddles 18 that is close to each other and the wall surface of the side of the arc plate 10 away from the connecting column 5 is smaller than the diameter of the collision ball 11, the collision The ball 11 will collide and contact with the side of the L-shaped pick 18 close to the curved plate 10 until the connecting rod 9 is deformed and bent under the force, and the collision ball 11 will separate from the corresponding L-shaped pick 18. Then, as the first connecting ring 7 continues to rotate, it will continue to collide and contact with the L-shaped pick 18 at other positions, so that the L-shaped pick 18 in contact with it will vibrate. The force generated by the vibration of the L-shaped pick 18 will cause the liquid molecules and bubbles in the molten metal inside the fixed mold 2 to produce high-frequency reciprocating motion, causing the bubbles to collide due to the difference in movement speed, resulting in the thinning and rupture of the liquid film on the bubble surface, and the small bubbles aggregate into large bubbles. The buoyancy of the large bubbles is significantly increased, making it easier to float to the liquid surface and discharge, thereby effectively discharging the gas in the metal inside the fixed mold 2, avoiding problems such as hollowing and bulging in the formed workpiece, improving the product qualification rate, and reducing production costs.

[0035] Since the cross-sections of the horizontal ends of the six L-shaped picks 18 close to the connecting column 5 are all conical, a better vibration effect can be generated after the collision ball 11 collides with it. At the same time, the distances between the vertical ends of the six L-shaped picks 18 and the connection points with the top surface inside the auxiliary groove 4 and the connecting column 5 are all different, and the horizontal ends of the six L-shaped picks 18 are highly staggered, which greatly improves the contact range with the fixed mold 2, and thus can effectively achieve the exhaust effect of the metal liquid at different positions inside the fixed mold 2.

[0036] The upper ends of the vertical ends of the two L-shaped linkage rods 13 are fixedly connected with a card block 14, which is composed of a diamond block and a rectangular block. The diamond block on the card block 14 is fixedly connected to the upper wall of the rectangular block on the card block 14. The card block 14 is an elastic block, and a sleeve hole 17 is opened at the position corresponding to the card block 14 on the extrusion block 16. The internal length of the sleeve hole 17 is smaller than the maximum diameter of the diamond block on the card block 14, and the internal length of the sleeve hole 17 is greater than the length of the rectangular block on the card block 14.

[0037] When the movable mold 3 is separated from the fixed mold 2, the extrusion block 14 will be affected by the diamond block on the block 14 and will drive the L-shaped linkage rod 13 to move upward and reset, until the L-shaped linkage rod 13 returns to its initial position and cannot move. At this time, the block 14 can be separated from the hole 17 again after being deformed by the force, thereby facilitating the repeated operation of the device. At the same time, during the upward movement of the L-shaped linkage rod 13, the collision ball 11 will also collide with the L-shaped pick 18 to vibrate it, and the vibration can now play a role in assisting demoulding.

[0038] The ejection mechanism includes a U-shaped lifting block 26, a top column 28 and an air pump 31. Two second movable holes 24 are symmetrically provided on the left and right side walls of the interior of the auxiliary groove 4. The interiors of the two second movable holes 24 are movably connected with U-shaped lifting blocks 26 that can move up and down. The two ends of the U-shaped lifting block 26 extend to the interior of the auxiliary groove 4 and the outside of the fixed mold 2 respectively. The upper wall surface of the U-shaped lifting block 26 at one end of the auxiliary groove 4 is equipped with two rotatable top columns 28 through bearings. The two top columns 28 correspond to the positions of the two sealing blocks 21 on the same side. A connecting hole 22 is provided on the inner bottom surface of the embedded groove 20. The upper end of the top column 28 extends to the interior of the corresponding connecting hole 22. The upper end of the top column 28 is fixedly connected to the lower wall surface of the corresponding sealing block 21. The positions of the two U-shaped lifting blocks 26 on the outside of the main device 1 are fixedly installed with air pumps 31 through the mounting plate 30. The output end of the air pump 31 is fixedly connected to the lower wall surface of the corresponding U-shaped lifting block 26.

[0039] During use, after the casting is completed, the staff starts the air pump 31 to drive the U-shaped lifting block 26 to move upward inside the corresponding second movable hole 24. The upward movement of the U-shaped lifting block 26 will drive the push column 28 to push the sealing block 21 upward, so as to achieve the effect of ejecting the workpiece formed inside the fixed mold 2. Since there are four sealing blocks 21 in total, the integrity of the demolding can be greatly guaranteed by simultaneously lifting them in multiple directions.

[0040] An auxiliary slide 29 is provided on the outer wall of the top column 28. The auxiliary slide 29 is a spiral groove. An auxiliary slider 23 is fixedly installed on the inner wall of the connecting hole 22 at a position corresponding to the auxiliary slide 29. The auxiliary slider 23 is movably connected to the inside of the corresponding auxiliary slide 29. Therefore, when the top column 28 lifts the sealing block 21 upward along with the U-shaped lifting block 26, the top column 28 is affected by the auxiliary slider 23 and the auxiliary slide 29, and will rotate during the rising period, thereby driving the sealing block 21 to rotate. The force generated by the rotation of the sealing block 21 can quickly separate it from the molded workpiece inside the fixed mold 2, thereby further improving the demolding efficiency.

[0041] Two T-shaped slots 25 are symmetrically provided on the inner wall of the second movable hole 24, and two T-shaped sliders 27 are fixedly connected to the outer wall of the U-shaped lifting block 26 at positions corresponding to the two T-shaped slots 25. The T-shaped sliders 27 are movably engaged with the inside of the corresponding T-shaped slots 25. By setting the T-shaped sliders 27 on the U-shaped lifting block 26 and cooperating with the T-shaped slots 25 inside the second movable hole 24, the effect of ensuring that the U-shaped lifting block 26 moves upward stably can be achieved.

[0042] A sealing ring 32 is fixedly connected to the upper wall surface of the fixed mold 2 to improve the sealing performance after the fixed mold 2 and the movable mold 3 are closed.

[0043] The working principle of the present invention is:

[0044] When in use, first inject the molten metal required for casting into the interior of the fixed mold 2, then start the hydraulic telescopic rod on the movable mold 3 to drive the movable mold 3 to move downward, at this time the extrusion block 16 on the movable mold 3 will first contact the corresponding L-shaped linkage rod 13, and as the movable mold 3 continues to fall, the extrusion block 16 will squeeze the L-shaped linkage rod 13 to move downward, causing the second connecting ring 12 to drag the first connecting ring 7 to move downward on the connecting column 5, at this time the first connecting ring 7 will rotate under the action of the arc embedded block 8, so the connecting rod 9 will drive the arc plate 10 and the collision ball 11 to do a circular motion with the connecting column 5 as the center, during this period, when the arc plate 10 passes through a certain L-shaped paddle 18, since the distance between the end of the six L-shaped paddles 18 that is close to each other and the wall surface of the side of the arc plate 10 away from the connecting column 5 is smaller than the diameter of the collision ball 11, the collision The ball 11 will collide and contact with the side of the L-shaped pick 18 close to the curved plate 10 until the connecting rod 9 is deformed and bent under the force, and the collision ball 11 will separate from the corresponding L-shaped pick 18. Then, as the first connecting ring 7 continues to rotate, it will continue to collide and contact with the L-shaped pick 18 at other positions, so that the L-shaped pick 18 in contact with it will vibrate. The force generated by the vibration of the L-shaped pick 18 will cause the liquid molecules and bubbles in the molten metal inside the fixed mold 2 to produce high-frequency reciprocating motion, causing the bubbles to collide due to the difference in movement speed, resulting in the thinning and rupture of the liquid film on the bubble surface, and the small bubbles aggregate into large bubbles. The buoyancy of the large bubbles is significantly increased, making it easier to float to the liquid surface and discharge, thereby effectively discharging the gas in the metal inside the fixed mold 2, avoiding problems such as hollowing and bulging in the formed workpiece, improving the product qualification rate, and reducing production costs.

[0045] When the movable mold 3 is separated from the fixed mold 2, the extrusion block 14 will be affected by the diamond block on the block 14 and will drive the L-shaped linkage rod 13 to move upward and reset, until the L-shaped linkage rod 13 returns to its initial position and cannot move. At this time, the block 14 can be separated from the hole 17 again after being deformed by the force, thereby facilitating the repeated operation of the device. At the same time, during the upward movement of the L-shaped linkage rod 13, the collision ball 11 will also collide with the L-shaped pick 18 to vibrate it, and the vibration can now play a role in assisting demoulding.

[0046] When in use, after the casting is completed, the staff drives the U-shaped lifting block 26 to move upward inside the corresponding second movable hole 24 by starting the air pump 31. The upward movement of the U-shaped lifting block 26 will drive the push column 28 to push the sealing block 21 upward, so that the workpiece formed inside the fixed mold 2 can be ejected. And since a total of four sealing blocks 21 are provided, the integrity of the demoulding can be greatly guaranteed by pushing up in multiple directions at the same time. The auxiliary slider 23 is movably connected to the inside of the corresponding auxiliary slide groove 29. Therefore, when the push column 28 pushes the sealing block 21 upward along with the U-shaped lifting block 26, the push column 28 is affected by the auxiliary slider 23 and the auxiliary slide groove 29, and will rotate during the rising period, thereby driving the sealing block 21 to rotate. The force generated by the rotation of the sealing block 21 can quickly separate it from the molded workpiece inside the fixed mold 2, thereby further improving the demoulding efficiency.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
