Abstract

This invention discloses an integrated die-casting machine for aluminum alloy vehicle frames, relating to the field of die-casting equipment technology. It includes a die-casting machine body, with a vibration mechanism for assisting demolding installed on the side of the lower mold body. A lifting mechanism for assisting casting demolding is installed at the bottom of the die-casting machine body. A translation mechanism for pushing the casting away from the mold is installed on the side of the lifting mechanism. A release mechanism for assisting casting lifting is also installed inside the lifting mechanism. By setting up the vibration mechanism, a hammer periodically impacts the side of the lower mold body of the die-casting machine body. High-frequency mechanical vibration reduces the static friction and adhesion between the casting and the mold cavity.

Description

Technical Field

[0001] This invention relates to the field of die-casting equipment technology, specifically to an integrated die-casting machine for aluminum alloy vehicle frames. Background Technology

[0002] In traditional automotive manufacturing, the chassis is one of the most critical structural components of a vehicle. It provides the basic load-bearing structure for the entire vehicle and, while ensuring stability and load-bearing capacity, also needs to be lightweight enough to adapt to various vehicle designs, meet fuel compatibility requirements, and accommodate passenger or cargo transportation needs. Currently, aluminum alloy subframes are primarily manufactured using die casting, which involves injecting molten metal under high pressure into a mold cavity to obtain a high-precision, high-strength casting of complex structures.

[0003] Currently, the unloading of high-temperature castings in the industry mostly relies on manual operation or simple robotic arms. However, in the traditional die-casting production process, due to the high temperature and high pressure environment involved in the die-casting process, the castings often generate large shrinkage stress after cooling and solidification, causing them to adhere tightly to the inside of the mold and making demolding difficult.

[0004] Therefore, this invention proposes an integrated die-casting machine for aluminum alloy vehicle frames to compensate for and improve the deficiencies of existing technologies. Summary of the Invention

[0005] In view of the above problems, the present invention provides an integrated die-casting machine for aluminum alloy vehicle frames, which can effectively solve the problem of difficult demolding caused by the cooling and solidification of castings in the prior art. To achieve the above objective, the embodiments of this application provide the following technical solutions: This invention discloses an integrated die-casting machine for aluminum alloy vehicle frames, including a die-casting machine body.

[0007] Furthermore, a first torsion spring is symmetrically sleeved on the outside of the rotating rod. One end of the first torsion spring is fixedly connected to the outside of the round rod, and the other end of the first torsion spring is fixedly connected to the side of the mounting plate.

[0008] Furthermore, the lifting mechanism includes a push rod that is slidably connected to the lower mold body of the die-casting machine body, and the push rod extends into the interior of the lower mold body of the die-casting machine body. A mounting base is fixedly connected to the bottom of the push rod, and a first spring is sleeved on the outside of the push rod, with the first spring located between the mounting base and the die-casting machine body.

[0009] Furthermore, a first lever is rotatably connected to the bottom of the mounting base, a bracket is rotatably connected to the middle of the first lever, the bracket is fixedly connected to the bottom of the die-casting machine body, and a connecting rod is rotatably connected to the end of the first lever away from the mounting base.

[0010] Furthermore, a second lever is rotatably connected to the end of the connecting rod away from the first lever, and a crossbar is rotatably connected to the middle of the second lever. Both ends of the crossbar are fixedly connected to the die-casting machine body, and the end of the second lever away from the connecting rod extends to the top of the mold body on the die-casting machine body.

[0011] Furthermore, the translation mechanism includes a support plate fixedly connected to the middle of the die-casting machine body, a slide rod slidably connected to the support plate, a push plate for pushing the casting to translate is fixedly connected to one end of the slide rod, a limit block is fixedly connected to the other end of the slide rod, and a second spring is sleeved on the outside of the slide rod, with the second spring located between the support plate and the push plate.

[0012] Furthermore, a pivot is rotatably connected to the top of the push plate, and a hook is fixedly connected to the outside of the pivot. The hook is engaged with the top of the support plate. A second torsion spring is also sleeved on the outside of the pivot. One end of the second torsion spring is fixedly connected to the side of the hook, and the other end of the second torsion spring is fixedly connected to the top of the push plate. An L-shaped rod for preventing the hook from sagging is also fixedly connected to the side of the push plate.

[0013] Furthermore, the translation mechanism also includes a lever fixedly connected to the side of the connecting rod. The upper part of the lever near the hook has a groove, and a deflection rod for pushing the hook to rotate upward is rotatably connected inside the groove.

[0014] Furthermore, the release mechanism includes a receiving cavity inside the top rod, with a gas supply pipe fixedly connected to the bottom of the receiving cavity, and the end of the gas supply pipe away from the receiving cavity connected to an external gas supply device. A movable block is symmetrically slidably connected in the cavity on the side of the receiving cavity, and an inclined surface is opened on the outer side of the movable block near the bottom. A third spring is symmetrically fixedly connected on the side of the movable block away from the inclined surface, and the end of the third spring away from the movable block is fixedly connected to the side wall of the receiving cavity. A vent hole is opened in the side wall of the receiving cavity, and a blocking block for sealing the vent hole is fixedly connected on the side of the movable block near the center of the receiving cavity. A connecting hole for conveying airflow to the lower mold cavity of the die-casting machine body is also provided in the cavity on the side of the receiving cavity.

[0015] The beneficial effects of this invention are as follows: 1. This device is equipped with a vibration mechanism that uses a hammer to periodically strike the side of the lower mold body of the die-casting machine. The high-frequency mechanical vibration reduces the static friction and adhesion between the casting and the mold cavity. The vibration can cause a small displacement of the metal lattice, eliminate stress concentration, and thus improve the fluidity of the casting. This not only reduces the mechanical damage to the mold and casting caused by forced ejection, but also reduces the demolding resistance, creating conditions for subsequent ejection actions.

[0016] 2. This device is equipped with a lifting mechanism that utilizes the lever principle. Through the linkage of the first lever, connecting rod and second lever, the force of the power source is transmitted to the ejector rod, which pushes the casting to slide and rise along the mold cavity. This not only provides a stable vertical ejection force, avoiding casting deformation or ejection defects caused by uneven force on a traditional single ejector rod, but also the first spring inside provides a buffering and reset function after the ejection action is completed.

[0017] 3. This device is equipped with a translation mechanism. Through the cooperation of the lever and the deflection rod, and the hook engagement and unlocking mechanism, the push plate can push the casting away from directly above the mold to a safe area after the ejection action is completed. This achieves seamless connection between demolding and unloading, avoids the risk of secondary adhesion or burns caused by the high-temperature casting staying above the mold for too long, and enables the casting to be demolded smoothly.

[0018] 4. This device, equipped with a release mechanism, employs pneumatic-assisted demolding. A receiving cavity and vent holes are incorporated within the ejector pin. High-pressure gas is supplied to the bottom of the mold cavity via an external air supply device. The gas flow enters the interface gap between the mold and the casting through a connecting hole. An air film is formed between the casting and the mold, reducing the coefficient of sliding friction. When the casting has a complex shape, deep cavities, or undercut structures, the permeation of air pressure can fill tiny gaps, balancing internal and external pressures and assisting the ejector pin in easily completing demolding. This effectively solves the demolding dead zone problem caused by vacuum adsorption or complex surfaces, further aiding in casting demolding. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] The present invention will be further described below with reference to embodiments.

[0031] See Figures 1 to 8 This embodiment of an aluminum alloy frame integrated die casting machine includes a die casting machine body 10. The lower mold body of the die casting machine body 10 is provided with a vibration mechanism 20 for assisting demolding. The bottom of the die casting machine body 10 is provided with a lifting mechanism 30 for assisting casting demolding. The side of the lifting mechanism 30 is provided with a translation mechanism 40 for pushing the casting away from the mold. The lifting mechanism 30 is also provided with a release mechanism 50 for assisting the casting to rise.

[0032] See Figure 1 , Figure 2 and Figure 3 The vibration mechanism 20 includes mounting plates 201 symmetrically fixedly connected to the surface of the die-casting machine body 10. A round rod 202 is rotatably connected between the two mounting plates 201. Multiple rotating rods 203 are fixedly connected to the outside of the round rod 202. A hammer 204 for impacting the lower mold body is fixedly connected to the top of each rotating rod 203 near the side of the lower mold body of the die-casting machine body 10.

[0033] The bottom of the two mounting plates 201 are also rotatably connected to rotating rods 205. The rotating rods 205 are fixedly connected to the outside of protrusions 206. Each protruding end of the protrusions 206 is rotatably connected to a roller 207. The rollers 207 are in rolling connection with the side of the rotating rods 203. A motor 209 is fixedly connected to the side of the mounting plate 201. The output end of the motor 209 is fixedly connected to one end of the rotating rods 205.

[0034] The rotating rod 203 is also symmetrically fitted with a first torsion spring 208. One end of the first torsion spring 208 is fixedly connected to the outside of the round rod 202, and the other end of the first torsion spring 208 is fixedly connected to the side of the mounting plate 201.

[0035] In actual operation, when the demolding operation begins, the motor 209 on the side of the mounting plate 201 starts, driving the rotating rod 205 to rotate. The protrusion 206 on the outside of the rotating rod 205 rotates accordingly. The protruding end of the protrusion 206 presses the side of the rotating rod 203 through the roller 207, overcoming the elastic force of the first torsion spring 208, causing the rotating rod 203 to swing around the axis of the round rod 202. When the protrusion 206 rotates past the highest point, the first torsion spring 208 resets, causing the rotating rod 203 to rebound quickly, causing the hammer 204 at the top of the rotating rod 203 to violently strike the side of the lower mold body of the die-casting machine body 10. As the rotating rod 205 continues to rotate, the hammer 204 periodically strikes the mold, generating high-frequency mechanical vibration. High-frequency vibration causes minute displacements in the metal lattice, reducing static friction and adhesion between the casting and the mold cavity. Vibration helps eliminate shrinkage stress concentration during casting cooling and solidification, improves stress release performance, and creates conditions for subsequent ejection. Compared with forced ejection, vibration-assisted ejection reduces mechanical damage to the mold and casting.

[0036] See Figure 1 , Figure 2 and Figure 4 The lifting mechanism 30 includes a push rod 301 that is slidably connected to the lower mold body of the die casting machine body 10, and the push rod 301 extends into the lower mold body of the die casting machine body 10. The bottom of the push rod 301 is fixedly connected to a mounting base 306, and a first spring 303 is sleeved on the outside of the push rod 301, and the first spring 303 is located between the mounting base 306 and the die casting machine body 10.

[0037] The bottom of the mounting base 306 is rotatably connected to a first lever 302, and the middle of the first lever 302 is rotatably connected to a bracket 307. The bracket 307 is fixedly connected to the bottom of the die-casting machine body 10, and the end of the first lever 302 away from the mounting base 306 is rotatably connected to a connecting rod 304.

[0038] The end of the connecting rod 304 away from the first lever 302 is rotatably connected to the second lever 305. The middle of the second lever 305 is rotatably connected to the crossbar 308. The two ends of the crossbar 308 are fixedly connected to the die-casting machine body 10. The end of the second lever 305 away from the connecting rod 304 extends to the top of the mold on the die-casting machine body 10.

[0039] In operation, when the hydraulic cylinder of the die-casting machine body 10 moves the upper mold body upward, the upper mold body moves the end of the second lever 305 away from the connecting rod 304 upward, causing the second lever 305 to swing around the crossbar 308. The end of the second lever 305 near the connecting rod 304 rotates downward, transmitting force to the first lever 302 through the connecting rod 304. The first lever 302 rotates around the bracket 307 in its middle, and the end of the first lever 302 away from the connecting rod 304 lifts upward, thereby pushing the mounting seat 306, which is rotatably connected to the first lever 302, to rise. The mounting seat 306 drives the ejector rod 301 to slide along the lower mold body of the die-casting machine body 10, ejecting the casting upward from the cavity. At the same time, the mounting seat 306 compresses and stores force on the first spring 303. After the ejection action is completed, the first spring 303 rebounds, providing cushioning and assisting the mechanism in resetting. By utilizing the lever principle to transmit power, the casting deformation or puncture defects caused by uneven force distribution in the traditional single ejector rod 301 are avoided, providing a stable vertical ejection force and ensuring smooth demolding of large vehicle frame castings.

[0040] See Figure 1 , Figure 2 , Figure 5 and Figure 6 The translation mechanism 40 includes a support plate 401 fixedly connected to the middle of the die-casting machine body 10. The support plate 401 is slidably connected to a slide rod 403. One end of the slide rod 403 is fixedly connected to a push plate 402 for pushing the casting to translate. The other end of the slide rod 403 is fixedly connected to a limit block 404. A second spring 405 is sleeved on the outside of the slide rod 403, and the second spring 405 is located between the support plate 401 and the push plate 402.

[0041] A rotating shaft 409 is rotatably connected to the top of the push plate 402. A hook 406 is fixedly connected to the outside of the rotating shaft 409. The hook 406 engages with the top of the support plate 401. A second torsion spring 408 is also sleeved on the outside of the rotating shaft 409. One end of the second torsion spring 408 is fixedly connected to the side of the hook 406, and the other end is fixedly connected to the top of the push plate 402. An L-shaped rod 407 is also fixedly connected to the side of the push plate 402 to prevent the hook 406 from sagging. The vertical end of the L-shaped rod 407 is placed on the bottom surface below the hook 406 and maintains sliding contact with it. In the non-working state, the L-shaped rod 407 physically supports the hook 406 from the bottom, counteracting the downward force applied by the second torsion spring 408 and preventing the hook 406 from sagging excessively and failing to engage precisely with the support plate 401 during reset.

[0042] The translation mechanism 40 also includes a lever 410 fixedly connected to the side of the connecting rod 304. A groove 411 is provided on the upper part of the lever 410 near the hook 406. A deflection rod 412 for pushing the hook 406 to rotate upward is rotatably connected inside the groove 411.

[0043] In operation, when not in use, the hook 406 on the top of the push plate 402 engages with the top of the support plate 401. At this time, the second spring 405 is compressed and stores energy, and the L-shaped rod 407 restricts the hook 406 from drooping. During die casting, the deflection rod 412 is positioned above the hook 406. In this case, the deflection rod 412 cannot push the hook 406, thus preventing the push plate 402 from translating and pushing the casting.

[0044] When the hydraulic cylinder of the die-casting machine body 10 moves the upper mold body upward, the connecting rod 304 drives the lever 410 and the deflecting rod 412 to enter below the hook 406. At this time, the casting is pushed out of the mold cavity by the push rod 301. Simultaneously, as the lever 410 and the deflecting rod 412 enter below the hook 406, when the deflecting rod 412 contacts the hook 406, the deflecting rod 412 rotates upward, preventing the deflecting rod 412 from moving the hook 406. As the lifting mechanism 30 pushes the casting out of the lower mold body, the hydraulic cylinder of the die-casting machine body 10 moves the upper mold body downward a certain distance. At this time, under the elastic force of the first spring 303, the lever 410 fixed on the connecting rod 304 moves downward. As the connecting rod 304 moves upward, the deflecting rod 412 on the upper part of the lever 410 is blocked by the groove 411, preventing it from rotating downward. This deflecting rod 412 then lifts one end of the hook 406, causing the hook 406 to rotate around the pivot 409 and disengage from the locking point of the support plate 401. At the moment the hook 406 unlocks, the compressed second spring 405 releases its elasticity, pushing the slide rod 403 to rapidly move the push plate 402 horizontally. The push plate 402 pushes the ejected casting away from directly above the mold to a safe area. After the push plate 402 reaches the end of its stroke, it is manually reset, and the hook 406, under the action of the second torsion spring 408, re-locks into the support plate 401. This prevents the high-temperature casting from remaining above the mold for too long, thus avoiding secondary adhesion due to residual heat. It quickly moves the high-temperature casting to a safe area, reducing the risk of burns to operators.

[0045] See Figure 1 , Figure 2 , Figure 7 and Figure 8The release mechanism 50 includes a receiving cavity 501 inside the top rod 301. A gas supply pipe 502 is fixedly connected to the bottom of the receiving cavity 501, and the end of the gas supply pipe 502 away from the receiving cavity 501 is connected to an external gas supply device. A moving block 504 is symmetrically slidably connected in the cavity on the side of the receiving cavity 501. An inclined surface 505 is provided on the outer side of the moving block 504 near the bottom. A third spring 506 is symmetrically fixedly connected on the side of the moving block 504 away from the inclined surface 505. The end of the third spring 506 away from the moving block 504 is fixedly connected to the side wall of the receiving cavity 501. A vent hole 503 is provided on the side wall of the receiving cavity 501. A blocking block 507 for sealing the vent hole 503 is fixedly connected on the side of the moving block 504 near the center of the receiving cavity 501. A connecting hole 508 for conveying airflow to the lower mold cavity of the die-casting machine body 10 is also provided in the cavity on the side of the receiving cavity 501.

[0046] In practice, when the top of the ejector pin 301 rises and enters the mold cavity, the moving block 504 moves outward under the force of the third spring 506. At this time, the blocking block 507 disengages from the vent hole 503. Then, the external air supply device delivers high-pressure gas to the receiving cavity 501 inside the ejector pin 301 through the air supply pipe 502. The high-pressure gas enters the interface gap between the mold and the casting through the vent hole 503 and the connecting hole 508, forming a thin air film on the contact surface. The air film reduces the sliding friction coefficient and balances the pressure inside and outside the cavity, assisting the ejector pin 301 in easily completing demolding. The air film technology reduces the sliding friction coefficient between the casting and the mold. At the same time, for frames with complex shapes, deep cavities, or undercut structures, air pressure can penetrate and fill tiny gaps, solving the problems of vacuum adsorption or demolding dead corners. It also avoids scratches on the surface of the casting caused by excessive friction, improving the surface quality of the product.

[0047] When the ejector pin 301 descends and resets, the inclined surface 505 on the side of the moving block 504 is squeezed by the mold, and the moving block 504 retracts into the cavity on the side of the ejector pin 301, causing the blocking block 507 to re-seal the vent hole 503.

[0048] To ensure successful demolding of the casting, the air pressure P required for airflow must strictly satisfy the critical dynamic equilibrium formula for demolding:

[0049] in, This refers to the effective force-bearing area at the bottom of the casting after the gas overflows through the connecting hole 508. It is the static friction coefficient between the metal lattice and the mold cavity. This is the normal pressure on the side wall. To account for the weight of the casting. Preferably, the initial air pressure threshold Pmin output by the external air supply device is set to 0.6-0.8MPa, and the pore diameter of the vent 503 is in the range of 1.5-2.5mm, so as to establish a stable high-pressure demolding air film.

[0050] Working principle: After die casting, the casting is first assisted in detaching from the mold by a vibration mechanism 20. Then, the casting is ejected from the mold cavity by a lifting mechanism 30. During ejection, a high-speed airflow is blown into the mold cavity by a release mechanism 50 to reduce the sliding friction coefficient between the casting and the mold, which helps the casting to be demolded. Finally, the ejected casting is pushed away from the mold by a translation mechanism 40, which avoids the high-temperature casting from staying above the mold for too long and causing secondary adhesion due to residual heat.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
