Description

Technical Field

[0001] The present application relates to the technical field of wheel hub casting, and in particular to a wheel hub casting device that is easy to demould. Background Art

[0002] With the rapid development of the automotive industry, the demand for wheel hubs continues to grow. The main manufacturing methods for automotive wheels are forging, casting, and spinning. Traditional mechanical demoulding uses a built-in ejector rod or hydraulic cylinder to drive the ejection mechanism to push the solidified wheel hub out of the cavity.

[0003] During the traditional mechanical demoulding process, the demoulding may become stuck, which requires increasing the mechanical ejection force to push the wheel hub out. However, using a greater force will cause an impact force after the wheel hub breaks away from the sticking point, causing a greater impact after the wheel hub falls, thereby causing damage to the wheel hub.

[0004] Based on this, there is an urgent need for a device that can buffer the speed of the wheel hub demoulding and moving downward to prevent the wheel hub from falling and causing damage due to impact, and to improve the demoulding effect. Summary of the Invention

[0005] This application aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] To this end, the present application provides a wheel hub casting device that is easy to demold, which can buffer the speed of the wheel hub being demolded and moved downward, prevent the wheel hub from falling and causing impact and damage, and improve the demolding effect.

[0007] This application provides a wheel hub casting device that facilitates demolding, comprising a lower mold assembly, an upper mold assembly, a movable assembly, a force storage assembly, and a speed control assembly. The upper mold assembly is mounted on the lower mold assembly; two movable assemblies are located on either side of the lower mold assembly; two force storage assemblies are mounted on each movable assembly to assist in demolding the wheel hub; and two speed control assemblies are mounted on each movable assembly to buffer the wheel hub's downward movement speed.

[0008] In some embodiments, the lower mold assembly includes: a base; a lower mold base, disposed on the base; a lower mold core, disposed on the lower mold base; multiple hydraulic boxes, each disposed on the base; and multiple side mold bases connected to each hydraulic box.

[0009] In this embodiment, the lower mold assembly cooperates with the upper mold assembly to complete the casting of the wheel hub.

[0010] In some embodiments, the upper mold assembly includes: a support frame, arranged on the base; a first oil cylinder, arranged on the support frame; an upper mold base, connected to the first oil cylinder; a plurality of first guide columns, respectively arranged on the upper mold base; and an upper mold core, arranged at the bottom of the upper mold base.

[0011] In this embodiment, the first oil cylinder pushes the upper die base downward, and a plurality of first guide columns are distributed circumferentially along the upper die base to form a stable constraint, ensuring that the upper die base moves only in the vertical direction, eliminating the risk of deviation or tilting.

[0012] In some embodiments, each moving component includes: a first fixed frame, fixed on the inner side of the support frame; a second oil cylinder, arranged on the first fixed frame; a telescopic column, connected to the second oil cylinder; a second guide column, arranged at the bottom of the first fixed frame; a movable rod, connected to the second guide column; a mounting seat, arranged at the end of the movable rod away from the second guide column; a first spring, arranged on the outside of the movable rod; a mounting frame, rotatably connected to the mounting seat, a convex groove being provided on the mounting frame, and the convex groove being matched with the mounting seat; two rubber blocks, arranged on the mounting frame.

[0013] In this embodiment, the second oil cylinder and the telescopic column push the rubber block to move so that the rubber block contacts the surface of the wheel hub. The second guide column is used to guide the movement of the mounting seat to move linearly to prevent deviation.

[0014] In some embodiments, each force storage assembly includes: a fixed block connected to the telescopic column; a connecting rod rotatably connected to the fixed block; a rotating member rotatably connected to the connecting rod, and the rotating member is rotatably connected to the mounting bracket; a torsion spring, one end of which is connected to the rotating member, and the other end of the torsion spring is connected to the mounting bracket.

[0015] In this embodiment, the connecting rod serves as a connecting member between the fixed block and the rotating member, and both are rotating connections. When the position of the rotating member is relatively fixed, the fixed block moves forward again, which will drive the connecting rod to rotate. The torsion spring is arranged between the rotating member and the mounting frame, and is used to be twisted and store force, so that the rotating member has the force to rotate downward.

[0016] In some embodiments, each speed control assembly includes: a vertical frame fixed on the telescopic column; an extrusion frame arranged on the vertical frame, and the vertical frame is movably connected to the extrusion frame; a second spring arranged on the extrusion frame; and a rubber wheel arranged at one end of the extrusion frame away from the second spring.

[0017] In this embodiment, the rubber wheel contacts the surface of the hub. When the hub moves downward due to gravity, the rubber wheel rubs against its surface, which buffers the downward movement speed of the hub and prevents the downward movement speed from being too fast and causing impact, which may cause the hub surface to bump and cause damage.

[0018] In some embodiments, each speed control assembly further includes: a rotating frame connected to the rotating member; a fixed seat fixedly connected to the vertical frame; a lifting frame arranged on the fixed seat; a third spring arranged on the fixed seat, the third spring being connected to the lifting frame; a locking block fixed on the lifting frame, and a groove is provided in the extrusion frame, the groove being used to accommodate the locking block.

[0019] In this embodiment, the cooperation between the locking block and the groove allows the lifting frame to be quickly raised or lowered to achieve locking or releasing when needed, thereby improving the response speed.

[0020] In some embodiments, the wheel hub casting device further includes: two interception assemblies for storing force on the second spring, each interception assembly including: a hanger fixed on the side of the support frame close to the first fixing frame; a blocker provided on the hanger, the blocker being in contact with the extrusion frame.

[0021] In this embodiment, the blocker limits the extrusion frame. When the wheel hub is buffered and decelerated, the blocker cancels the limit on the extrusion frame, and the second spring restores its elastic performance, so that the extrusion frame moves, allowing the extrusion frame to respond quickly, thereby increasing the corresponding speed and shortening the corresponding time.

[0022] In some embodiments, the wheel hub casting device also includes: a demolding assembly for demolding the wheel hub, the demolding assembly including: two second fixed frames, arranged on the upper mold base; two third oil cylinders, arranged on each second fixed frame; a push plate, arranged at the bottom end of the third oil cylinder; and multiple push rods, respectively arranged at the bottom of the push plate.

[0023] In this embodiment, the third oil cylinder controls the push rod to apply pressure to the wheel hub for demolding. Uniform force is applied to the wheel hub by multiple push rods. The uniform force can prevent the wheel hub from being deformed due to excessive local force, and can prevent the wheel hub from being stuck or deformed due to uneven local force.

[0024] In some embodiments, the wheel hub casting device further includes: a material receiving assembly for receiving the demolded wheel hub, the material receiving assembly including: a support platform disposed on the base; an angle controller disposed on the support platform; and a material receiving plate rotatably connected to the angle controller.

[0025] In this embodiment, the support table is used to support and fix the receiving tray, and the angle controller is set between the support table and the receiving tray. The transfer controller controls the rotation of the support table to adjust the support table for receiving the material.

[0053] In order to more clearly understand the above objectives, features and advantages of the present application, the following further specifically describes the present application with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0054] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, however, the present application can also be implemented in other manners different from those described herein, and therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0055] The following refers to Figures 1 to 14 A wheel hub casting device facilitating demolding is provided according to some embodiments of the present application.

[0056] As Figure 1 shown, the wheel hub casting device facilitating demolding provided according to some embodiments of the present application includes a lower mold assembly 100, an upper mold assembly 200, a moving assembly 300, a force storage assembly 400 and a speed control assembly 500. The upper mold assembly 200 is arranged on the lower mold assembly 100; two moving assemblies 300 are arranged on the two sides of the upper mold assembly 200; two force storage assemblies 400 are arranged on each moving assembly 300 for assisting in demolding of the wheel hub; and two speed control assemblies 500 are arranged on each moving assembly 300 for buffering the downward speed of the wheel hub.

[0057] In this embodiment, the lower mold assembly 100 serves as a basic support structure for wheel hub casting and is fixed on a casting station to provide an installation reference for the upper mold assembly 200; the upper mold assembly 200 is installed above the lower mold assembly 100 and cooperates with the lower mold assembly 100 to enclose a forming cavity of the wheel hub to perform wheel hub casting work; the moving assembly 300 enables the force storage assembly 400 and the speed control assembly 500 to move flexibly to adapt to the demolding requirements of wheel hubs of different specifications; the force storage assembly 400 provides additional auxiliary power during demolding of the wheel hub, so that the wheel hub is more easily separated from the upper mold assembly 200, and the time and manpower required for demolding are reduced; and the speed control assembly 500 buffers the downward speed of the wheel hub through resistance friction to ensure that the wheel hub moves stably downward during demolding and avoids damage to the wheel hub or affecting the demolding quality due to excessively fast downward speed.

[0058] In some possible embodiments, as Figure 2As shown, the lower mold assembly 100 includes: a base 110; a lower mold base 120, which is arranged on the base 110; a lower mold core 130, which is arranged on the lower mold base 120; a plurality of hydraulic boxes 140, which are respectively arranged on the base 110; and a plurality of side mold bases 150, which are connected to each hydraulic box 140.

[0059] In this embodiment, the base 110 serves as the supporting foundation of the lower mold assembly 100; the lower mold base 120 is fixed to the base 110, providing an installation foundation for the lower mold core 130; the lower mold core 130 is embedded in the groove of the lower mold base 120; the hydraulic box 140 is arranged around the base 110, and each hydraulic box 140 independently controls a side mold base 150 to realize the lateral mold closing action; the surface of the side mold base 150 is in contact with the edge of the lower mold core 130.

[0060] When the lower mold assembly 100 is working, the side mold base 150 is in the demolding position in the initial state, the piston rod of the hydraulic box 140 contracts, the hydraulic system supplies oil to the hydraulic box 140, and the piston rod pushes the side mold base 150 to move toward the center. After the side mold base 150 contacts the edge of the lower mold core 130, the hydraulic system ensures that the pressure is stable, so that the upper mold assembly 200 is pressed down, and together with the lower mold core 130 and the side mold base 150, the workpiece is formed. After forming, the pressure is released through the hydraulic box 140, and the upper mold assembly 200 drives the formed wheel hub to rise and demold.

[0061] In some possible embodiments, such as Figure 3 As shown, the upper mold assembly 200 includes: a support frame 210, which is arranged on the base 110; a first oil cylinder 220, which is arranged on the support frame 210; an upper mold base 230, which is connected to the first oil cylinder 220; a plurality of first guide columns 240, which are respectively arranged on the upper mold base 230; and an upper mold core 250, which is arranged at the bottom of the upper mold base 230.

[0062] In this embodiment, the support frame 210 supports the upper mold assembly 200; the first oil cylinder 220 controls the upward and downward movement of the upper mold base 230 and the upper mold core 250; a total of four first guide columns 240 are provided, which cooperate with the upper mold base 230 in a straight line to eliminate the risk of offset and ensure that the upper mold core 250 is pressed down vertically.

[0063] In some possible embodiments, such as Figure 4-7As shown, each moving component 300 includes: a first fixed frame 310, fixed on the inner side of the support frame 210; a second oil cylinder 320, arranged on the first fixed frame 310; a telescopic column 330, connected to the second oil cylinder 320; a second guide column 340, arranged at the bottom of the first fixed frame 310; a movable rod 350, connected to the second guide column 340; a mounting seat 360, arranged at one end of the movable rod 350 away from the second guide column 340; a first spring 370, arranged on the outside of the movable rod 350; a mounting frame 380, rotatably connected to the mounting seat 360, and a convex groove is provided on the mounting frame 380, which cooperates with the mounting seat 360; two rubber blocks 390, arranged on the mounting frame 380.

[0064] In this embodiment, the first fixed frame 310 is fixed to the inner side of the support frame 210; the second oil cylinder 320 is horizontally installed inside the first fixed frame 310, and the end of the piston rod is connected to the telescopic column 330; the second guide column 340 cooperates with the telescopic column 330 in a linear manner to ensure that the telescopic column 330 moves horizontally; the movable rod 350 is arranged inside the telescopic column 330 for cooperating with the force storage assembly 400; the mounting seat 360 is fixed to the end of the movable rod 350; the first spring 370 is sleeved on the outside of the movable rod 350, and its two ends are respectively in contact with the telescopic column 330 and the mounting seat 360 to provide pre-tightening force; the mounting frame 380 is rotatably connected to the mounting seat 360, and a convex groove is provided on the surface of the mounting frame 380, which cooperates with the mounting seat 360 to limit the mounting frame 380 to only allow downward rotation; two rubber blocks 390 are fixed on both sides of the mounting frame 380.

[0065] When the moving assembly 300 is working, the second oil cylinder 320 is initially contracted and the first spring 370 is in a non-deformed state. When the wheel hub needs to be assisted in demolding, oil is supplied through the second oil cylinder 320, and the piston rod pushes the telescopic column 330 and the movable rod 350 to move toward the wheel hub position, so that the rubber block 390 of the mounting frame 380 contacts the wheel hub surface. Since the rubber block 390 has already contacted the wheel hub surface, when the second oil cylinder 320 pushes the mounting frame 380 to move, the mounting seat 360 and the mounting frame 380 will not move anymore, so that the movable rod 350 will be contracted into the inside of the telescopic column 330, and the telescopic column 330 continues to move forward, so that the first spring 370 contracts, thereby triggering the storage assembly 400.

[0066] In some possible embodiments, such as Figure 5-7 As shown, each force storage assembly 400 includes: a fixed block 410, connected to the telescopic column 330; a connecting rod 420, rotatably connected to the fixed block 410; a rotating member 430, rotatably connected to the connecting rod 420, and the rotating member 430 is rotatably connected to the mounting bracket 380; a torsion spring 440, one end of which is connected to the rotating member 430, and the other end of the torsion spring 440 is connected to the mounting bracket 380.

[0067] When the second oil cylinder 320 further pushes the telescopic column 330, the mounting frame 380 and the mounting seat 360 are resisted by the wheel hub and will not move anymore. When the telescopic column 330 is driven to move, the movable rod 350 will retract into the telescopic column 330, and only the telescopic column 330 will continue to move forward. The fixed block 410 pushes the connecting rod 420 forward, so that the connecting rod 420 will push the rotating member 430 to rotate in the mounting seat 360. Since the rubber block 390 of the mounting frame 380 contacts the wheel hub and cannot rotate, the torsion spring 440 is twisted and stored, so that the mounting frame 380 has a downward rotation force, that is, the mounting frame 380 and the rubber block 390 generate a downward force on the wheel hub to assist the wheel hub demolding.

[0068] In some possible embodiments, such as Figure 8-10 As shown, each speed control assembly 500 includes: a vertical frame 510, fixed on the telescopic column 330; an extrusion frame 520, arranged on the vertical frame 510, and the vertical frame 510 is movably connected to the extrusion frame 520; a second spring 530, arranged on the extrusion frame 520; and a rubber wheel 540, arranged at one end of the extrusion frame 520 away from the second spring 530.

[0069] In this embodiment, the vertical frame 510 is fixed on the telescopic column 330. As the telescopic column 330 moves, the extrusion frame 520 and the second spring 530 are in a compressed state. The extrusion frame 520 is unrestricted and the second spring 530 releases energy. The extrusion frame 520 and the rubber wheel 540 move rapidly along the vertical frame 510, so that the rubber wheel 540 contacts the wheel hub and generates an instantaneous impact. The instantaneous friction between the rubber wheel 540 and the wheel hub increases sharply, offsetting the impact generated after the wheel hub breaks away from the stuck point, providing stable friction for the subsequent smooth descent of the wheel hub, and buffering the speed of the wheel hub during the downward movement to prevent damage caused by impact caused by excessive downward movement.

[0070] In some possible embodiments, such as Figure 8-10 As shown, each speed control assembly 500 also includes: a rotating frame 550, connected to the rotating member 430; a fixed seat 560, fixedly connected to the vertical frame 510; a lifting frame 570, arranged on the fixed seat 560; a third spring 580, arranged on the fixed seat 560, and the third spring 580 is connected to the lifting frame 570; a locking block 590, fixed on the lifting frame 570, and a groove is provided in the extrusion frame 520, and the groove is used to accommodate the locking block 590.

[0071] In this embodiment, when the mounting frame 380 rotates as the wheel hub is demolded and falls, the rotating frame 550 rotates accordingly, thereby pushing the lifting frame 570 upward, causing the third spring 580 to be stretched, and the lifting frame 570 drives the locking block 590 to move upward, so that the locking block 590 disengages from the groove of the extrusion frame 520, and the extrusion frame 520 is unrestricted.

[0072] In some possible embodiments, such as Figure 11 As shown, the wheel hub casting device also includes: two interception assemblies 600, which are used to store force on the second spring 530, and each interception assembly 600 includes: a hanger 610, which is fixed to the side of the support frame 210 close to the first fixing frame 310; a blocker 620, which is arranged on the hanger 610, and the blocker 620 is in contact with the extrusion frame 520.

[0073] In this embodiment, the blocker 620 contacts the extrusion frame 520. When the extrusion frame 520 moves toward the wheel hub along with the moving assembly 300, the protruding end of the blocker 620 intercepts the extrusion frame 520 to stretch and store force for the second spring 530 until the locking block 590 locks the slot of the extrusion frame 520. The protruding end of the blocker 620 then releases the interception of the extrusion frame 520, completing the force storage action of the second spring 530.

[0074] In some possible embodiments, such as Figure 12 、 Figure 13 As shown, the wheel hub casting device also includes: a demolding assembly 700 for demolding the wheel hub, and the demolding assembly 700 includes: two second fixing frames 710, which are arranged on the upper mold base 230; two third oil cylinders 720, which are arranged on each second fixing frame 710; a push plate 730, which is arranged at the bottom end of the third oil cylinder 720; and a plurality of push rods 731, which are respectively arranged at the bottom of the push plate 730.

[0075] In this embodiment, in the initial state, the third oil cylinder 720 is in a compressed state. When the tire is cast, the tire is still adhered to the upper mold core 250. The third oil cylinder 720 pushes the push plate 730 and the push rod 731 downward. The push rod 731 contacts the surface of the workpiece, applies a uniform demolding force, and pushes the workpiece out of the upper mold core 250.

[0076] In some possible embodiments, such as Figure 14 As shown, the hub casting device also includes: a material receiving assembly 800 for receiving the demolded hub, and the material receiving assembly 800 includes: a support platform 810, which is arranged on the base 110; an angle controller 820, which is arranged on the support platform 810; and a material receiving tray 830, which is rotatably connected to the angle controller 820.

[0077] In this embodiment, after the upper mold core 250 moves up, the receiving tray 830 is controlled by the angle controller 820 to move above the lower mold base 120, so that the wheel hub is completely separated from the upper mold core 250 and then falls onto the receiving tray 830. The receiving tray 830 can absorb the impact of the wheel hub through the polyurethane buffer layer to prevent the wheel hub from rebounding or being damaged.

[0078] When the wheel hub casting device is working, the hydraulic system supplies oil to the hydraulic tank 140, the piston rod pushes the side mold base 150 to move to the center and fit with the edge of the lower mold core 130, so that the piston rod of the first oil cylinder 220 extends and pushes the upper mold core 250 to press down, which together with the lower mold core 130 and the side mold base 150 forms a cavity. The metal liquid is injected into the cavity through the casting system to form a wheel hub. After the wheel hub is formed, the piston rod of the first oil cylinder 220 is retracted to drive the upper mold base 230 and the upper mold core 250 to rise. At this time, the wheel hub is adhered to the upper mold core 250. The push plate 730 and the push rod 731 are pushed downward by the third oil cylinder 720, the push rod 731 contacts the surface of the wheel hub, and a uniform demolding force is applied to push the wheel hub out of the upper mold core 250. When the demolding is stuck, the second oil cylinder 320 is started to supply oil, which drives the telescopic column 330 and the movable rod 350 to move to the position of the wheel hub. The rubber block 390 of the mounting bracket 380 contacts the surface of the wheel hub. Since the rubber block 390 has contacted the surface of the wheel hub, the mounting bracket 380 will not move when it is pushed again, so that the first spring 370 is retracted, the movable rod 350 is shortened, the fixed block 410 moves with the telescopic column 330 to drive the connecting rod 420 to rotate the rotating member 430. At this time, the torsional spring 440 is compressed, the mounting bracket 380 is rotated downward, the rubber block 390 generates a downward force on the wheel hub to assist the demolding of the wheel hub. When the mounting bracket 380 rotates, the rotating bracket 550 pushes the lifting bracket 570 upward, the third spring 580 is stretched, the locking block 590 is separated from the groove of the extrusion bracket 520, and the blocker 620 cancels the limiting of the extrusion bracket 520 at this time. The second spring 530 releases energy, the extrusion bracket 520 and the rubber wheel 540 move rapidly, contact the wheel hub, and make the wheel hub descend stably. The angle controller 820 drives the receiving tray 830 to move above the lower mold base 120, the wheel hub falls onto the receiving tray 830 after being separated from the upper mold core 250, and the polyurethane buffer layer absorbs the impact energy to prevent the wheel hub from being damaged after falling off.
