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 automobile industry, the demand for wheel hubs continues to grow. The main manufacturing methods for automobile wheels are forging, casting and spinning. Traditional mechanical demoulding uses a built-in ejector or hydraulic cylinder to drive the ejection mechanism to push the solidified wheel hub out of the cavity. In the traditional mechanical demoulding process, the demoulding may get 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 is separated from the sticking point, resulting in a greater impact after the wheel hub falls, causing damage to the wheel hub.

[0003] Based on this, there is an urgent need for a device that can buffer the demoulding and downward movement speed of the wheel hub, prevent the wheel hub from falling and causing impact and damage, and improve the demoulding effect. Summary of the invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, the present application provides a hub casting device that is easy to demold, which can buffer the hub's demolding and downward movement speed, prevent the hub from falling and causing impact and damage, and improve the demolding effect.

[0006] The present application provides a wheel hub casting device that facilitates demoulding, comprising a lower mold assembly, an upper mold assembly, a moving assembly, a force storage assembly, and a speed control assembly. The upper mold assembly is arranged on the lower mold assembly; two moving assemblies are arranged on both sides of the lower mold assembly; two force storage assemblies are arranged on each moving assembly to assist the wheel hub in demoulding; and two speed control assemblies are arranged on each moving assembly to buffer the speed at which the wheel hub moves downward.

[0007] In some embodiments, the lower mold assembly includes: a base; a lower mold base, which is disposed on the base; a lower mold core, which is disposed on the lower mold base; a plurality of hydraulic boxes, which are separately disposed on the base; and a plurality of side mold bases, which are connected to each hydraulic box.

[0008] In this embodiment, the lower mold assembly cooperates with the upper mold assembly to complete the casting of the wheel hub.

[0009] In some embodiments, the upper mold assembly includes: a support frame, arranged on a 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, arranged on the upper mold base; and an upper mold core, arranged at the bottom of the upper mold base.

[0010] In this embodiment, the first oil cylinder pushes the upper die base downward. A plurality of first guide columns are circumferentially distributed along the upper die base to form a stable constraint, ensuring that the upper die base moves only in the vertical direction and eliminating the risk of offset or tilt.

[0011] In some embodiments, each moving component includes: a first fixing frame fixed inside the support frame; a second oil cylinder disposed on the first fixing frame; a telescopic column connected to the second oil cylinder; a second guide column disposed at the bottom of the first fixing frame; a movable rod connected to the second guide column; a mounting seat disposed at one end of the movable rod away from the second guide column; a first spring disposed outside the movable rod; a mounting frame rotatably connected to the mounting seat, with a convex groove provided on the mounting frame, and the convex groove cooperating with the mounting seat; and two rubber blocks disposed on the mounting frame.

[0012] 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 hub. The second guide column is used to guide the movement of the mounting seat in a straight line to prevent offset.

[0013] In some embodiments, each energy storage component includes: a fixing block connected to the telescopic column; a connecting rod rotatably connected to the fixing block; a rotating member rotatably connected to the connecting rod, and the rotating member rotatably connected to the mounting frame; and 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 frame.

[0014] In this embodiment, the connecting rod serves as a connecting member between the fixing block and the rotating member, and both are rotatably connected. When the position of the rotating member is relatively fixed, if the fixing block moves forward again, it will drive the connecting rod to rotate. The torsion spring is disposed between the rotating member and the mounting frame and is used to be twisted and store energy, so that the rotating member has a force to rotate downward.

[0015] In some embodiments, each speed control component includes: an upright frame fixed on the telescopic column; a pressing frame disposed on the upright frame, and the upright frame is movably connected to the pressing frame; a second spring disposed on the pressing frame; and a rubber wheel disposed at one end of the pressing frame away from the second spring.

[0016] In this embodiment, the rubber wheel contacts the surface of the hub. When the hub moves downward under the action of gravity, friction is generated between the rubber wheel and its surface, thereby buffering the downward movement speed of the hub, preventing the downward movement speed from being too fast and causing an impact, and preventing damage to the surface of the hub due to knocking.

[0017] In some embodiments, each speed control component further includes: a rotating frame connected to the rotating member; a fixed seat fixedly connected to the upright frame; a lifting frame disposed on the fixed seat; a third spring disposed on the fixed seat, and the third spring is connected to the lifting frame; a locking block fixed on the lifting frame, and a groove is provided in the pressing frame for accommodating the locking block.

[0018] In this embodiment, the cooperation between the locking block and the groove allows for the quick lifting and lowering of the lifting frame when needed, achieving locking or releasing, and improving the response speed.

[0019] In some embodiments, the hub casting device further includes: two intercepting components for storing energy of the second spring. Each intercepting component includes: a hanging bracket fixed to one side of the support frame close to the first fixed frame; a stopper disposed on the hanging bracket, and the stopper contacts the extrusion frame.

[0020] In this embodiment, the stopper limits the extrusion frame. When buffering and decelerating the hub, the limit on the extrusion frame is cancelled by the stopper, and the second spring restores its elastic performance, then the extrusion frame moves, enabling the extrusion frame to respond quickly, improving the response speed and shortening the response time.

[0021] In some embodiments, the hub casting device further includes: a demoulding component for demoulding the hub. The demoulding component includes: two second fixed frames disposed on the upper die base; two third oil cylinders disposed on each second fixed frame; a push plate disposed at the bottom end of the third oil cylinder; and a plurality of push rods respectively disposed at the bottom of the push plate.

[0022] In this embodiment, the third oil cylinder controls the push rods to apply pressure to the hub for demoulding. Uniform force is applied to the hub through the plurality of push rods. Uniform force application can prevent the hub from deforming due to excessive local force, and can also prevent the hub from getting stuck or deformed due to uneven local force.

[0023] In some embodiments, the hub casting device further includes: a receiving component for receiving the demoulded hub. The receiving component includes: a support table disposed on the base; a corner controller disposed on the support table; and a receiving tray rotatably connected to the corner controller.

[0024] In this embodiment, the support table is used to support and fix the receiving tray. The corner controller is disposed between the support table and the receiving tray, and the corner controller controls the rotation of the support table to adjust the receiving of the support table.

[0025] Compared with the prior art, the above technical solutions provided by the present application at least include the following technical effects: A hub casting device facilitating demolding provided by the present application can buffer the downward movement speed of the hub during demolding, prevent damage caused by the impact of the falling hub, and improve the demolding effect.

[0029] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0030] In the following description, many specific details are set forth in order to fully understand the present application. However, the present application can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0031] Refer to the following Figures 1 to 14 A wheel hub casting device that facilitates demolding is described according to some embodiments of the present application.

[0032] like Figure 1 As shown, the wheel hub casting device for easy demoulding provided in 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. Among them, the upper mold assembly 200 is arranged on the lower mold assembly 100; two moving assemblies 300 are arranged on both sides of the upper mold assembly 200; two force storage assemblies 400 are arranged on each moving assembly 300 to assist the wheel hub in demoulding; two speed control assemblies 500 are arranged on each moving assembly 300 to buffer the downward movement speed of the wheel hub.

[0033] In this embodiment, the lower mold assembly 100 serves as the basic support structure for wheel hub casting and is fixed on the 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 together with the lower mold assembly 100, it forms a molding cavity of the wheel hub for wheel hub casting; the moving assembly 300 enables the power storage assembly 400 and the speed control assembly 500 to move flexibly to meet the demolding requirements of wheel hubs of different specifications; the power storage assembly 400 provides additional auxiliary power during the demolding process of the wheel hub, making it easier for the wheel hub to detach from the upper mold assembly 200, reducing the time and manpower required for demolding; the speed control assembly 500 buffers the speed of the wheel hub's downward movement through resistance friction, ensuring that the wheel hub moves downward smoothly during the demolding process, and avoiding damage to the wheel hub or affecting the demolding quality due to excessive downward movement.

[0034] In some possible embodiments, Figure 2 As 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 separately arranged on the base 110; and a plurality of side mold bases 150, which are connected to each hydraulic box 140.

[0035] In this embodiment, the base 110 serves as the bearing foundation of the lower mold assembly 100; the lower mold base 120 is fixed to the base 110 to provide 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 boxes 140 are 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.

[0036] When the lower die assembly 100 is working, in the initial state, the side die base 150 is in the die-removing position. The piston rod of the hydraulic tank 140 contracts. The hydraulic system supplies oil to the hydraulic tank 140, and the piston rod pushes the side die base 150 to move towards the center. After the side die base 150 contacts the edge of the lower die core 130, the hydraulic system ensures stable pressure. Then, the upper die assembly 200 presses down to jointly complete the workpiece forming with the lower die core 130 and the side die base 150. After forming, the hydraulic pressure in the hydraulic tank 140 is released, and the upper die assembly 200 drives the formed hub to rise and demold.

[0037] In some possible embodiments, as Figure 3 shown, the upper die assembly 200 includes: a support frame 210 disposed on the base 110; a first oil cylinder 220 disposed on the support frame 210; an upper die base 230 connected to the first oil cylinder 220; a plurality of first guide columns 240 separately disposed on the upper die base 230; and an upper die core 250 disposed at the bottom of the upper die base 230.

[0038] In this embodiment, the support frame 210 supports the upper die assembly 200; the first oil cylinder 220 controls the upward and downward movement of the upper die base 230 and the upper die core 250; a total of four first guide columns 240 are provided, which are linearly matched with the upper die base 230 to eliminate the risk of offset and ensure that the upper die core 250 presses down vertically.

[0039] In some possible embodiments, as Figures 4 - 7 shown, each moving assembly 300 includes: a first fixing frame 310 fixed to the inner side of the support frame 210; a second oil cylinder 320 disposed on the first fixing frame 310; a telescopic column 330 connected to the second oil cylinder 320; a second guide column 340 disposed at the bottom of the first fixing frame 310; a movable rod 350 connected to the second guide column 340; a mounting seat 360 disposed at one end of the movable rod 350 away from the second guide column 340; a first spring 370 disposed outside the movable rod 350; a mounting frame 380 rotatably connected to the mounting seat 360, with a convex groove provided on the mounting frame 380, and the convex groove is matched with the mounting seat 360; and two rubber blocks 390 disposed on the mounting frame 380.

[0040] In this embodiment, the first fixing frame 310 is fixed to the inner side of the support frame 210; the second oil cylinder 320 is horizontally installed inside the first fixing frame 310, and the end of the piston rod is connected to the telescopic column 330; the second guide column 340 is in linear cooperation with the telescopic column 330 to ensure the horizontal movement of the telescopic column 330; the movable rod 350 is arranged inside the telescopic column 330 and is used to cooperate with the energy storage assembly 400; the mounting seat 360 is fixed to the end of the movable rod 350; the first spring 370 is sleeved outside the movable rod 350, and both ends are in contact with the telescopic column 330 and the mounting seat 360 respectively to provide a pre-tightening force; the mounting frame 380 is rotatably connected to the mounting seat 360, and the surface of the mounting frame 380 is provided with a convex groove, which cooperates with the mounting seat 360 to limit the mounting frame 380 to only allow downward rotation; two rubber blocks 390 are fixed to both sides of the mounting frame 380.

[0041] When the moving assembly 300 works, in the initial state, the second oil cylinder 320 contracts, and the first spring 370 is in a non-deformed state. When it is necessary to assist in demolding the wheel hub, the second oil cylinder 320 is supplied with oil, and the piston rod pushes the telescopic column 330 and the movable rod 350 to move towards the wheel hub position. As a result, the rubber block 390 of the mounting frame 380 contacts the surface of the wheel hub. Since the rubber block 390 has already contacted the surface of the wheel hub, when the second oil cylinder 320 pushes the mounting frame 380 to move again, the mounting seat 360 and the mounting frame 380 will no longer move. As a result, the movable rod 350 will be retracted into the telescopic column 330, and then the telescopic column 330 continues to move forward, so that the first spring 370 contracts and triggers the energy storage assembly 400.

[0042] In some possible embodiments, as Figures 5 - 7 shown, each energy storage assembly 400 includes: a fixed block 410, which is connected to the telescopic column 330; a connecting rod 420, which is rotatably connected to the fixed block 410; a rotating member 430, which is rotatably connected to the connecting rod 420, and the rotating member 430 is rotatably connected to the mounting frame 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 frame 380.

[0043] In this embodiment, the fixed block 410 is fixed on the telescopic column 330. The fixed block 410 and the rotating member 430 are arranged on both sides of the connecting rod 420 and are both rotatably connected. The rotating member 430 and the mounting bracket 380 are installed in the mounting seat 360. Then, when the second oil cylinder 320 further pushes the telescopic column 330, the mounting bracket 380 and the mounting seat 360 will no longer move due to the resistance of the wheel hub. The telescopic column 330 is driven to move, and the movable rod 350 will contract into the telescopic column 330. Only when the telescopic column 330 continues 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 bracket 380 contacts the wheel hub and cannot rotate, the torsion spring 440 is twisted and stores energy, so that the mounting bracket 380 has a downward turning force, that is, the mounting bracket 380 and the rubber block 390 generate a downward force on the wheel hub to assist in demolding the wheel hub.

[0044] In some possible embodiments, as Figures 8 - 10 shown, each speed control component 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.

[0045] In this embodiment, the vertical frame 510 is fixed on the telescopic column 330 and moves together with the telescopic column 330. The extrusion frame 520 and the second spring 530 are in a compressed state. The extrusion frame 520 is released from the limit, and the second spring 530 releases energy. The extrusion frame 520 and the rubber wheel 540 quickly move along the vertical frame 510, so that the rubber wheel 540 contacts the wheel hub and generates an instantaneous impact. Then, the instantaneous friction force 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 a stable friction force for the subsequent smooth descent of the wheel hub, buffering the speed during the downward movement of the wheel hub, and preventing damage caused by too fast downward movement speed and generating impact.

[0046] In some possible embodiments, as Figures 8 - 10 shown, each speed control component 500 further 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 arranged in the extrusion frame 520 for accommodating the locking block 590.

[0047] 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, so that the third spring 580 is 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 unlimited.

[0048] In some possible embodiments, 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.

[0049] 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.

[0050] In some possible embodiments, Figure 12 , Figure 13 As shown, the wheel hub casting device also includes: a demolding assembly 700, which is used for demolding the wheel hub. 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 arranged at the bottom of the push plate 730.

[0051] 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 to move downward. The push rod 731 contacts the surface of the workpiece, applies a uniform demoulding force, and pushes the workpiece out of the upper mold core 250.

[0052] In some possible embodiments, Figure 14 As shown, the wheel hub casting device also includes: a material receiving assembly 800 for receiving the demoulded wheel 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 plate 830, which is rotatably connected to the angle controller 820.

[0053] In this embodiment, after the upper mold core 250 moves the wheel hub tooling upward, the angle controller 820 controls the receiving tray 830 to move to above the lower mold base 120. Then, after the wheel hub is completely detached from the upper mold core 250, it falls onto the receiving tray 830. The receiving tray 830 absorbs the impact of the wheel hub through the polyurethane buffer layer to prevent the wheel hub from rebounding or being damaged.

[0054] When the wheel hub casting device that is easy to demould is working, 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 and fit with the edge of the lower mold core 130, so that the piston rod of the first oil cylinder 220 extends, pushing the upper mold core 250 downward, and together with the lower mold core 130 and the side mold base 150, a cavity is formed. The molten metal is injected into the cavity through the casting system and cooled to form a wheel hub. After the wheel hub is formed, the piston rod of the first oil cylinder 220 contracts, driving the upper mold base 230 and the upper mold core 250 to rise. At this time, the wheel hub adheres to the upper mold core 250, and 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 applies a uniform demoulding force to push the wheel hub out of the upper mold core 250. When the demoulding is stuck, the second oil cylinder 320 is started to supply oil, and the telescopic column 330 and the movable rod 350 are pushed toward the wheel hub position. The rubber block 390 of the mounting frame 380 contacts the surface of the wheel hub. Since the rubber block 390 has already contacted the surface of the wheel hub, the mounting frame 380 is pushed again. When moving, the mounting frame 380 will not move anymore, so the first spring 370 contracts, the movable rod 350 shortens, the fixed block 410 moves with the telescopic column 330 so that the connecting rod 420 drives the rotating member 430 to rotate, at this time the torsion spring 440 is compressed, the mounting frame 380 rotates downward, so that the rubber block 390 generates a downward force on the wheel hub to assist the wheel hub demoulding, when the mounting frame 380 rotates, the rotating frame 550 pushes the lifting frame 570 upward, the third spring 580 stretches, and the locking block 59 0 is separated from the groove of the extrusion frame 520. At this time, the blocker 620 cancels the limit on the extrusion frame 520, and the second spring 530 releases energy. The extrusion frame 520 and the rubber wheel 540 move quickly and contact the wheel hub, so that the wheel hub drops steadily. The angle controller 820 drives the receiving plate 830 to move to the top of the lower die seat 120. The wheel hub is separated from the upper mold core 250 and falls to the receiving plate 830. The polyurethane buffer layer absorbs the impact energy to prevent the wheel hub from falling after separation and generating a large impact force, thereby causing damage.
