Description

Technical Field

[0001] The invention relates to the technical field of low-temperature casting, in particular to a low-temperature casting device for an automobile aluminum alloy wheel hub. Background Art

[0002] The wheel hub, also known as the rim, is a cylindrical component that is centrally mounted on the axle and used to support the inner contour of the tire. Common automobile wheel hubs include steel wheel hubs and aluminum alloy wheel hubs. Steel wheel hubs have high strength and are often used in large trucks. However, steel wheel hubs are heavy and have a simple appearance, which does not conform to today's low-carbon and fashionable concepts. They are gradually being replaced by aluminum alloy wheel hubs. Low-temperature casting generally refers to the process of injecting liquid into a sealed container, then filling the container with compressed air to make the liquid rise and fill the entire container, and then waiting for cooling and forming before demolding. This method is suitable for casting large, thin-walled, complex castings, and has a high metal recovery rate. Existing technologies cannot quickly install and replace molds, and have low applicability.

The patent includes an operating table, fixedly connected to the four corners of the top of the operating table with fixed rods, fixedly connected to the top of the fixed rods with a fixed plate, fixedly mounted on the top of the fixed plate with a first cylinder, fixedly connected to the output shaft of the first cylinder with a slide, and the slide slidably engaged between the four fixed rods. A clamping mechanism is provided at the bottom of the slide, and an injection molding mechanism is provided at the bottom of the operating table. A mold removal mechanism is provided on the side of the slide near the clamping mechanism at the top of the operating table, and an ejection mechanism is provided inside the slide. By providing the mold removal mechanism, the receiving tray rotates to a suitable position as the slide moves vertically, and the injection molded parts of the automobile wheel are received and transported to the next process, thereby improving the continuity of work and the efficiency of sending the automobile wheel molded parts to the next processing procedure. Although the patent solves the above problems, there are still problems such as the inability to quickly install and replace the mold, only being able to process a single wheel hub, and low applicability. Therefore, a low-temperature casting device for automobile aluminum alloy wheels is proposed to solve the above problems. Summary of the Invention

The output end of the die-casting machine passes through the lower surface of the top of the support frame from the upper surface of the support frame. The movable clamping block passes through the upper surface of the pressing plate from the lower surface of the pressing plate, and the upper surface of the movable lower template and the lower surface of the side mold seat contact each other, and the linear motor is started, and the linear motor drives the left and right side mold seats to approach each other and merge. After the side mold seats are merged, the die-casting machine is started, and the die-casting machine drives the pressing plate to press down, and the pressing plate drives the upper mold seat to press down. When the pressing plate supports the top of the side mold seat, the aluminum liquid is injected into the mold through the injection port, and the casting of the wheel hub embryo is completed after the aluminum liquid cools down. When it is necessary to cast wheels with different inner diameters, the pin is pulled to disengage the pin from the movable clamping block, and the movable clamping block cannot be fixed after losing the locking of the pin. On the pressure plate, after the top surface of the upper die seat is fitted with the lower surface of the pressure plate, the movable clamp is inserted into the pressure plate and aligned with the fixed clamp. At this time, push the pin so that the pin is inserted into the movable clamp to quickly install the upper die seat on the pressure plate. During demoulding, the die-casting machine drives the pressure plate and the upper die seat to rise, and the wheel hub embryo is first driven by the upper die seat to separate from the side die seat and the movable lower template. Pulling the movable lower template out of the clamp frame in advance can avoid the wheel hub embryo from sticking to the movable lower template. During casting, first fit the left and right movable lower templates together, and press the pressure plate downward to drive the positioning rod to move down and insert it into the positioning hole.

The slight friction generated by the contact between the roller and the inner wall of the side die seat causes the roller and the rotating rod to rotate in the sleeve ring. The die-casting machine drives the pressure plate and the upper die seat to move downward. After the upper die seat contacts the transmission sleeve, it pushes it to move downward. When the transmission sleeve moves downward, it drives the sleeve downward through the connecting ring and the connecting rod. The sleeve then drives the rotating rod and the roller downward through the limit clamp ring, and finally moves to the outside of the mold. When the die-casting machine drives the pressure plate and the upper die seat to move upward, the elastic return action of the spring lifts the transmission sleeve, and at this time the movable lower template is pulled out of the clamping frame.

[0007] Preferably, the oscillation device includes a movable slide, a slide rod, an upper resistance ring, a lower resistance ring, an oscillation plate, a screw, and a nut. The movable slide is opened on both sides of the casting table, the slide rod is slidably connected to the inner surface of the movable slide, the upper resistance ring is fixedly connected to the circumferential surface of the slide rod, the lower resistance ring is fixedly connected to the circumferential surface of the slide rod, the oscillation plate is clamped on the circumferential surface of the slide rod, the screw is fixedly connected to the top end of the slide rod, and the nut is threadedly connected to the circumferential surface of the screw.

[0008] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0009] 1. In the low-temperature casting device for automobile aluminum alloy wheels, the movable clamping block cannot be fixed to the pressure plate after losing the locking pin, so that the upper die seat can be quickly disassembled, and then the upper die seat of different diameters can be replaced according to the inner diameter of the wheel hub to be cast. The upper die seat can be quickly installed on the pressure plate by pushing the pin so that the pin is inserted into the movable clamping block, which not only improves the applicability of the device, but also improves the convenience of use. Pulling the movable lower template out of the clamping frame in advance can avoid the wheel embryo and the movable lower template from sticking, resulting in the upper die seat being unable to lift the wheel embryo and reducing the processing efficiency. The movable lower template is locked by the positioning rod and cannot move, which avoids the displacement of the movable lower template during casting and causing leakage.

[0010] 2. In the low-temperature casting device for automobile aluminum alloy wheels, the release agent adhered to the inner wall of the side mold seat can prevent the wheel embryo from sticking to the side mold seat, resulting in difficulty in demolding, or damage to the wheel embryo due to forced demolding. After the roller contacts the inner wall of the side mold seat, the release agent is evenly applied, further improving the demolding effect. The roller and the rotating rod rotate in the ring to prevent only one side of the roller from contacting the inner wall of the side mold seat to wipe off the release agent, promoting the effect of uniform application. The movable lower template is pulled out of the card frame, and the application device can be moved between the two side mold seats without manual disassembly or movement, thereby improving ease of use.

[0011] 3. The low-temperature casting device for automobile aluminum alloy wheels uses an oscillation plate to knock on the side mold base to break the bubbles generated when the aluminum liquid cools, avoiding the formation of air holes on the wheel embryo after cooling, thereby improving the quality of wheel casting. The oscillation plate can be lifted up and quickly removed from the slide bar. Conversely, the oscillation plate can be quickly installed on the slide bar, allowing staff to quickly replace the oscillation plate, thereby improving ease of use. The oscillation plate moves back and forth left and right to knock on the side mold base, allowing the device to automatically knock on the side mold base at a uniform speed, thereby improving ease of use and the effect of eliminating bubbles, thereby further improving the quality of the wheel embryo after molding.

[0022] See also Figures 1-8One embodiment of the present invention is: a low-temperature casting device for an automobile aluminum alloy wheel hub, comprising a casting table 1, a support frame 2 is fixedly connected to the upper surface of the casting table 1, a die-casting machine 3 is fixedly connected to the upper surface of the support frame 2, a linear motor 4 is fixedly connected to the upper surface of the casting table 1, a clamping frame 66 is fixedly connected to the movable end of the linear motor 4, a side die holder 5 is fixedly connected to the upper surface of the clamping frame 66, a pressure plate 6 is fixedly connected to the output end of the die-casting machine 3, a liquid injection port 61 is opened on the inner side of the pressure plate 6, and the upper surface of the pressure plate 6 is fixedly connected to the upper surface of the pressure plate 6. There is a fixed block 62, the inner surface of the fixed block 62 is slidably connected with a latch 65, the circumferential surface of the latch 65 is clamped with a movable block 64, the lower surface of the movable block 64 is fixedly connected with an upper mold base 63, the inner surface of the card frame 66 is slidably connected with a movable lower template 67, the inner side of the movable lower template 67 is provided with an adjustment groove 68, the inner side of the movable lower template 67 is provided with a positioning hole 69, the lower surface of the pressure plate 6 is fixedly connected with a positioning rod 610, and the movable block 64 cannot continue to be fixed on the pressure plate 6 after losing the locking of the latch 65. , so that the upper die seat 63 can be quickly disassembled, and then the upper die seat 63 of different diameters can be replaced according to the inner diameter of the wheel hub to be cast, and the latch 65 is pushed to insert the latch 65 into the movable block 64, so that the upper die seat 63 can be quickly installed on the pressing plate 6, which not only improves the applicability of the device, but also improves the convenience of use. A coating device 7 for coating the inner wall of the mold with a release agent is provided below the support frame 2, and an oscillation device 8 is provided below the support frame 2 to prevent bubbles from being generated during the cooling process of the aluminum liquid. The output end of the die casting machine 3 is connected to the die casting machine 3. The upper surface of the support frame 2 passes through the lower surface of the top of the support frame 2, and the movable clamping block 64 passes through the upper surface of the pressure plate 6 from the lower surface of the pressure plate 6. The upper surface of the movable lower template 67 and the lower surface of the side mold base 5 are in contact with each other. Pulling the movable lower template 67 out of the clamping frame 66 in advance can avoid the hub embryo from sticking to the movable lower template 67, resulting in the upper mold base 63 being unable to lift the hub embryo and reducing the processing efficiency. The movable lower template 67 is locked by the positioning rod 610 and cannot move, which avoids the displacement of the movable lower template 67 during casting and causes leakage.

[0023] Working principle: Start the linear motor 4, which drives the left and right side mold seats 5 to approach each other and merge. After the side mold seats 5 merge, start the die-casting machine 3, which drives the pressure plate 6 to press down, and the pressure plate 6 drives the upper mold seat 63 to press down. When the pressure plate 6 is against the top of the side mold seat 5, the aluminum liquid is injected into the mold through the injection port 61, and the casting of the wheel hub embryo is completed after the aluminum liquid cools down. When it is necessary to cast wheels with different inner diameters, pull the pin 65 to disengage the pin 65 from the movable block 64. The movable block 64 cannot continue to be fixed on the pressure plate 6 after losing the lock of the pin 65, so that the upper mold seat 63 can be quickly disassembled, and then the upper mold seat 63 of different diameters is replaced according to the inner diameter of the wheel hub that needs to be cast. After the top surface of the upper mold seat 63 is fitted with the lower surface of the pressure plate 6, the movable block 64 is inserted into the pressure plate 6 and fixed. The block 62 is aligned, and at this time, the pin 65 is pushed so that the pin 65 is inserted into the movable block 64, so that the upper die seat 63 can be quickly installed on the pressure plate 6, which not only improves the applicability of the device, but also improves the convenience of use. During demolding, the die-casting machine 3 drives the pressure plate 6 and the upper die seat 63 to rise, and the wheel hub embryo is first driven by the upper die seat 63 to separate from the side die seat 5 and the movable lower template 67. Pulling the movable lower template 67 out of the card frame 66 in advance can avoid the wheel hub embryo and the movable lower template 67 from sticking, resulting in the upper die seat 63 being unable to lift the wheel hub embryo and reducing the processing efficiency. During casting, the left and right movable lower templates 67 are first fitted together, and the pressure plate 6 is pressed down to drive the positioning rod 610 to move down and insert it into the positioning hole 69. At this time, the movable lower template 67 is locked by the positioning rod 610 and cannot move, which avoids the displacement of the movable lower template 67 during casting and causes leakage.

[0024] See also Figures 1-8The present invention also has the advantages that the present invention can realize the demoulding of the wheel hub by the support frame 71 of the present invention, and the support frame 71 of the present invention can realize the demoulding of the wheel hub by the support frame 71 of the present invention. The locking cam 77 is locked, and locking cam 771 is locked, so that locking cam 772 and locking cam 771 can be locked together, thereby guaranteeing that locking cam 77 can be locked together.

[0025] Working principle: Before starting casting, spray the release agent onto the inner wall of the side mold seat 5, and then start the linear motor 4. The linear motor 4 drives the left and right side mold seats 5 to separate, so that the wheel hub embryo is separated from the side mold seat 5. The release agent adhered to the inner wall of the side mold seat 5 can prevent the wheel hub embryo from sticking to the side mold seat 5, which makes demoulding difficult, or forced demoulding causes damage to the wheel hub embryo. Start the motor, and the motor drives the slide shaft 75 to rotate through the output shaft. The slide shaft 75 drives the transmission sleeve 76 to rotate through the spline. The transmission sleeve 76 drives the connecting ring 77 to rotate. The connecting ring 77 drives the connecting rod 78 to rotate along the axis of the transmission sleeve 76. The connecting rod 78 then drives the rotating rod 72 to rotate circumferentially through the collar 79. The rotating rod 72 drives the circumferential surface of the roller 71 to rotate. After the roller 71 contacts the inner wall of the side mold seat 5, the release agent is evenly applied, which further improves the demoulding effect. The roller 71 and the side mold seat 5 are connected. The slight friction force generated by the contact of the inner wall of the die base 5 causes the roller 71 and the rotating rod 72 to rotate in the sleeve ring 79, preventing only one side of the roller 71 from contacting the inner wall of the side die base 5 to wipe off the mold release agent, thereby promoting the uniform coating effect. The die-casting machine 3 drives the pressure plate 6 and the upper die base 63 to move downward. After the upper die base 63 contacts the transmission sleeve 76, it pushes it to move downward. When the transmission sleeve 76 moves downward, it drives the sleeve 79 downward through the connecting ring 77 and the connecting rod 78. The sleeve 79 then drives the rotating rod 72 and the roller 71 downward through the limiting clamping ring 73, and finally moves to the outside of the mold. After the die-casting machine 3 drives the pressure plate 6 and the upper die base 63 to move upward, the elastic return action of the spring lifts the transmission sleeve 76. At this time, the movable lower template 67 is pulled out of the card frame 66, and the smearing device 7 can be moved between the two side die bases 5 without manual disassembly or movement, thereby improving the convenience of use.

[0026] See also Figures 1-8On the basis of the above embodiment, in another embodiment of the present invention, the oscillation device 8 includes a movable chute 81, a slide rod 82, an upper contact ring 83, a lower contact ring 84, an oscillation plate 85, a screw 86, and a nut 87.

The circumferential surface of the wheel hub 85 is struck by the oscillation plate 85 on the side mold base 5 to break the bubbles generated when the aluminum liquid is cooled, thereby avoiding the generation of pores on the wheel hub embryo after cooling, thereby improving the quality of wheel hub casting. The oscillation plate 85 is lifted up and quickly removed from the slide bar 82. Conversely, the oscillation plate 85 can be quickly installed on the slide bar 82, so that the staff can quickly replace the oscillation plate 85, thereby improving the convenience of use. The oscillation device 8 also includes an L-shaped connecting plate 88, an elastic telescopic rod 89, a connecting slide 810, a transmission push rod 811, a transmission arc plate 812, a cam 813, and an L-shaped connecting plate. The connecting plate 88 is fixedly connected to both sides of the inner surface of the casting table 1, the elastic telescopic rod 89 is fixedly connected to the side of the L-shaped connecting plate 88 close to the chute shaft 75, the connecting slide 810 is fixedly connected to the end of the elastic telescopic rod 89 close to the chute shaft 75, the transmission push rod 811 is fixedly connected to the side of the connecting slide 810 away from the elastic telescopic rod 89, the transmission arc plate 812 is fixedly connected to the end of the transmission push rod 811 away from the connecting slide 810, the cam 813 is fixedly connected to the circumferential surface of the transmission sleeve 76, the screw 86 passes through the inner wall of the oscillation plate 85 and the top surface of the oscillation plate 85, and the nut 8 The bottom surface of 7 and the top surface of the oscillation plate 85 are in contact with each other, the top surface of the upper contact ring 83 and the bottom surface of the oscillation plate 85 are in contact with each other, the bottom surface of the lower contact ring 84 and the upper surface of the casting table 1 are in contact with each other, the bottom surface of the connecting slide 810 and the bottom upper surface of the L-shaped connecting plate 88 are in contact with each other, the upper surface of the transmission push rod 811 and the bottom end of the slide bar 82 are fixedly connected, and the oscillation plate 85 moves back and forth left and right to knock on the side mold base 5, so that the device can automatically knock on the side mold base 5 at a uniform speed, which improves the convenience of use and the effect of eliminating bubbles, and further improves the quality of the wheel hub embryo after molding.

[0027] Working principle: During the cooling process of the aluminum liquid, the slide bar 82 is pushed to slide back and forth in the movable slide groove 81, and the slide bar 82 drives the oscillation plate 85 to move back and forth, so that the oscillation plate 85 knocks the side mold base 5, and the bubbles generated when the aluminum liquid is cooled are broken, so as to avoid the generation of air holes on the wheel hub embryo after the cooling is completed, thereby improving the quality of the wheel hub casting. The nut 87 is twisted to disengage the nut 87 from the screw rod 86, and then the oscillation plate 85 is disengaged from the limit of the nut 87. At this time, the oscillation plate 85 can be lifted up and quickly removed from the slide bar 82. Conversely, the oscillation plate 85 can be quickly installed on the slide bar 82, so that the staff can quickly replace the oscillation plate 85, which improves the convenience of use. The upper mold base 63 pushes the transmission sleeve 76 to move downward, and the transmission sleeve 76 drives the cam 813 to move downward, so that the cam 813 moves between the left and right transmission arc plates 812. At the same time, the rotation of the transmission sleeve 76 can drive the cam 813 to rotate. When the cam 813 rotates, it pushes the transmission arc plate 812 to move to the side away from the transmission sleeve 76. The transmission arc plate 812 drives the transmission push rod 811 to move. The transmission push rod 811 drives the slide bar 82 to move. The slide bar 82 then drives the oscillation plate 85 to move to the side away from the side mold base 5. Then the elastic reset effect of the elastic telescopic rod 89 pushes the connecting slide 810 to move to the side close to the transmission sleeve 76. The connecting slide 810 drives the transmission push rod 811 to approach the transmission sleeve 76. The transmission push rod 811 then drives the oscillation plate 85 to approach the side mold base 5 through the slide bar 82, so that the oscillation plate 85 moves back and forth left and right to knock the side mold base 5, so that the device can automatically knock the side mold base 5 at a uniform speed, thereby improving the convenience of use and the effect of eliminating bubbles, and further improving the quality of the wheel hub embryo after molding.
