Description

Technical Field

[0001] This invention belongs to the field of copper casting technology, specifically relating to a pouring device for casting special copper castings. Background Technology

[0002] Special copper castings are objects with specific shapes, sizes, and properties obtained by pouring, injecting, sucking, or other casting methods into a pre-prepared sand core mold after smelting liquid metal, cooling, and subsequent processing such as grinding.

[0003] Patent CN212734128U describes a casting device for special copper castings. It uses a liftable inner cylinder installed inside an outer cylinder to pour raw materials into the mold while keeping the diversion hopper stationary. It has the advantage of adjusting the casting process according to the specific specifications and volume of the mold. However, the height of its discharge port is fixed and cannot adapt to casting molds of different heights, so the equipment needs further improvement. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a casting device for casting special copper castings, which has the advantages of being able to adapt to molds of different heights, automatic sealing and fixed moving wheels.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a casting device for casting special copper castings, comprising an outer cylinder and a ground, the outer cylinder comprising a barrel body, the outer wall of the barrel body being connected to a first inlet, a second inlet, and a third inlet, a counterweight base being fixedly connected to the bottom outer wall of the barrel body, a sliding groove being provided on the inner wall of the barrel body, an inner cylinder being slidably connected to the inner wall of the outer cylinder, the inner cylinder comprising a casting barrel, a sliding block being fixedly connected to the outer wall of the casting barrel, a convex surface being fixedly connected to the bottom of the inner wall of the casting barrel, a discharge port being provided on the inner wall of the casting barrel, the outer wall of the inner cylinder being slidably connected to the inner wall of a lifting device, a first sealing machine being fixedly connected to the outer wall of the outer cylinder, a second sealing machine being fixedly connected to the outer wall of the outer cylinder, and a third sealing machine being fixedly connected to the outer wall of the outer cylinder.

[0006] Through the above technical solution, the inner cylinder can slide and rise on the inner wall of the outer cylinder, thus changing the height of the inner cylinder. The inner wall at the bottom of the inner cylinder has three discharge ports, which correspond to the first, second, and third inlet ports, respectively, and the heights of the three ports are different. The raw material can only be discharged when the discharge ports correspond one-to-one with the three outlets. This can adapt to different sizes and heights of casting molds. The bottom of the casting barrel is convex, which can improve the discharge effect.

[0007] Preferably, the inner wall of the ground is rotatably connected to a rotating base, the top outer wall of the rotating base is fixedly connected to a fixing frame, the inner wall of the fixing frame is provided with a clamp, the inner wall of the clamp is provided with a table frame, and the outer wall of the table frame is fixedly connected to a mounting base.

[0008] Through the above technical solution, the table frame is a mobile frame. The mounting base on the top of the table frame is used to install the casting mold, and the casting mold can be replaced. When the table frame moves onto the fixed frame, it will press the clamp, thereby fixing the moving wheels at the bottom of the table frame and preventing the table frame from moving. By rotating the base, it can move along the limiting groove opened on the ground, so that it can be aligned with the first, second, and third drainage ports at different positions.

[0009] Preferably, the first sealing machine includes a limiting slider and a fixing block. A motor is fixedly connected to the outer wall of the fixing block, and a screw is fixedly connected to the output end of the motor. The inner wall of the screw is slidably connected to the inner wall of the limiting slider. A connecting bearing is threadedly connected to the outer wall of the screw, and a sealing plate is fixedly connected to the outer wall of the connecting bearing.

[0010] Through the above technical solution, the first sealing machine, the second sealing machine, and the third sealing machine are used to seal the first inlet, the second inlet, and the third inlet, respectively, thereby preventing raw material leakage. The motor can rotate the screw, and the connecting bearing connected to it will drive the sealing plate to move up and down. The sealing plate is a baffle used to block the outlet.

[0011] Preferably, the clamp includes a force-bearing plate and a hydraulic rod. Two clamps are rotatably connected to the inner wall of the force-bearing plate. A connecting rod is fixedly connected to the bottom outer wall of the force-bearing plate. A locking block is fixedly connected to one end of the connecting rod. A second spring is provided on the outer wall of the connecting rod. A locking block is fixedly connected to one end of the hydraulic rod. A first spring is provided on the outer wall of the hydraulic rod.

[0012] With the above technical solution, after the moving wheel presses on the force plate, the force plate moves down, and then the two clamps installed on the force plate will clamp the moving wheel, and the locking block at the bottom of the force plate will insert between the locking blocks set by the hydraulic rod. This can restrict the position of the table frame and prevent the table frame from moving randomly. Activating the hydraulic rod to separate the locking block and the locking block will allow the locking block to move upward without restriction. Pushing the table frame can push the table frame out of the clamp.

[0013] Preferably, the rotating base includes a base plate, and a motor is fixedly connected to the top outer wall of the base plate, and a rotating wheel is fixedly connected to the output end of the motor.

[0014] With the above technical solution, the motor is installed on the base plate. After the motor rotates the wheel, the wheel will move on the limiting groove on the ground.

[0015] Preferably, the fixing frame includes a first connecting frame, an inclined plate is fixedly connected to the outer wall of the first connecting frame, and a second connecting frame is fixedly connected to the outer wall of the inclined plate.

[0016] Through the above technical solution, the fixing frame is used to install the clamps, and the inclined plate can facilitate the movement of the table frame.

[0017] Preferably, the table frame includes a support leg, a wheel block is fixedly connected to the bottom outer wall of the support leg, a movable wheel is fixedly connected to the bottom outer wall of the wheel block, a contact block is fixedly connected to the outer wall of the support leg, and a contact wheel is provided on the inner wall of the contact block.

[0018] With the above technical solution, the table frame moves by means of casters. When the contact block comes into contact with the outer cylinder, the contact wheel will reduce the stability and friction of the table frame during rotation.

[0019] Preferably, the ground surface includes a cement floor, and a limiting groove is formed in the inner wall of the cement floor.

[0020] With the above technical solution, the limiting groove is circular and concentric with the outer cylinder, so that the distance between the table frame and the outer cylinder will not change when the table frame rotates.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The inner cylinder can slide and rise on the inner wall of the outer cylinder, thus changing the height of the inner cylinder. The inner wall at the bottom of the inner cylinder has three discharge ports, which correspond to the first, second, and third inlet ports, respectively. The heights of the three ports are different. The raw material can only be discharged when the discharge ports correspond to the three outlets one by one. This can adapt to different sizes and heights of casting molds. The bottom of the casting barrel is convex, which can improve the discharge effect.

[0023] 2. The table frame is a mobile frame. The mounting base on the top of the table frame is used to install the casting mold, and the casting mold can be replaced. When the table frame is moved to the fixed frame, it will press the clamp, thereby fixing the moving wheels at the bottom of the table frame and preventing the table frame from moving. By rotating the base, it can move along the limiting groove opened on the ground, so that it can be aligned with the first, second and third drainage ports at different positions.

[0024] 3. The first, second, and third sealing machines are used to seal the first, second, and third inlet ports, respectively, to prevent raw material leakage. The motor can rotate the screw, which in turn causes the connecting bearing to move the sealing plate up and down. The sealing plate is used to block the outlet. Attached Figure Description

[0039] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-13 This invention provides a technical solution: a casting device for casting special copper castings, comprising an outer cylinder 1 and a ground 12. The outer cylinder 1 includes a barrel body 100, with a first inlet 101, a second inlet 102, and a third inlet 103 connected to the outer wall of the barrel body 100. A counterweight base 104 is fixedly connected to the bottom outer wall of the barrel body 100. A groove 105 is formed on the inner wall of the barrel body 100. An inner cylinder 2 is slidably connected to the inner wall of the outer cylinder 1. The inner cylinder 2 includes a casting tank 200. A sliding block 201 is fixedly connected to the outer wall of the casting barrel 200. A convex surface 202 is fixedly connected to the bottom of the inner wall of the casting barrel 200. A discharge port 203 is opened on the inner wall of the casting barrel 200. The outer wall of the inner cylinder 2 is slidably connected to the inner wall of the lifting equipment 3. A first sealing machine 4 is fixedly connected to the outer wall of the outer cylinder 1. A second sealing machine 5 is fixedly connected to the outer wall of the outer cylinder 1. A third sealing machine 6 is fixedly connected to the outer wall of the outer cylinder 1.

[0041] In this embodiment, the inner cylinder 2 can slide and rise on the inner wall of the outer cylinder 1, thereby changing the height of the inner cylinder 2. The inner wall at the bottom of the inner cylinder 2 has three discharge ports 203, which correspond to the first inlet 101, the second inlet 102 and the third inlet 103 respectively, and the heights of the three are different. The raw material can only be discharged when the discharge ports 203 correspond to the three outlets one by one. This can adapt to the size and height of different casting molds. The bottom of the casting barrel 200 is a convex surface 202, which can improve the discharge effect.

[0042] Specifically, a rotating base 7 is rotatably connected to the inner wall of the ground 12, a fixed frame 8 is fixedly connected to the top outer wall of the rotating base 7, a clamp 9 is provided on the inner wall of the fixed frame 8, a table frame 10 is provided on the inner wall of the clamp 9, and an installation base 11 is fixedly connected to the outer wall of the table frame 10.

[0043] In this embodiment, the table frame 10 is a movable frame. The mounting base 11 on the top of the table frame 10 is used to install the casting mold, and the casting mold can be replaced. When the table frame 10 moves onto the fixed frame 8, it will press the clamp 9, thereby fixing the moving wheel 1002 at the bottom of the table frame 10, thus preventing the table frame 10 from moving. By rotating the base 7, it can move along the limiting groove 1201 opened on the ground 12, so that it can be aligned with the first drain port 101, the second drain port 102 and the third drain port 103 at different positions.

[0044] Specifically, the first sealing machine 4 includes a limiting slider 400 and a fixing block 401. A motor 403 is fixedly connected to the outer wall of the fixing block 401. A screw 404 is fixedly connected to the output end of the motor 403. The inner wall of the screw 404 is slidably connected to the inner wall of the limiting slider 400. A connecting bearing 402 is threadedly connected to the outer wall of the screw 404. A sealing plate 405 is fixedly connected to the outer wall of the connecting bearing 402.

[0045] In this embodiment, the first sealing machine 4, the second sealing machine 5, and the third sealing machine 6 are used to seal the first outlet 101, the second outlet 102, and the third outlet 103, respectively, to prevent raw material leakage. The motor 403 can rotate the screw 404, so that the connecting bearing 402 connected to it will drive the sealing plate 405 to move up and down. The sealing plate 405 is a baffle used to block the outlet 203.

[0046] Specifically, the clamp 9 includes a force plate 900 and a hydraulic rod 904. Two clamps 901 are rotatably connected to the inner wall of the force plate 900. A connecting rod 902 is fixedly connected to the bottom outer wall of the force plate 900. A locking block 903 is fixedly connected to one end of the connecting rod 902. A second spring 907 is provided on the outer wall of the connecting rod 902. A locking block 906 is fixedly connected to one end of the hydraulic rod 904. A first spring 905 is provided on the outer wall of the hydraulic rod 904.

[0047] In this embodiment, after the moving wheel 1002 presses against the force plate 900, the force plate 900 moves downward. Then, the two clamps 901 installed on the force plate 900 will clamp the moving wheel 1002, and the locking block 903 at the bottom of the force plate 900 will be inserted between the locking blocks 906 set on the hydraulic rod 904. This can restrict the position of the table frame 10 and prevent the table frame 10 from moving arbitrarily. Activating the hydraulic rod 904 will separate the locking blocks 906 and the locking blocks 903, so that the upward movement of the locking blocks 903 will be unrestricted. Pushing the table frame 10 can push the table frame 10 out of the clamp 9.

[0048] Specifically, the rotating base 7 includes a base plate 700, a motor 701 is fixedly connected to the top outer wall of the base plate 700, and a rotating wheel 702 is fixedly connected to the output end of the motor 701.

[0049] In this embodiment, the motor 701 is mounted on the base plate 700. After the motor 701 rotates the wheel 702, the wheel 702 will move on the limiting groove 1201 on the ground 12.

[0050] Specifically, the fixing frame 8 includes a first connecting frame 800, an inclined plate 801 is fixedly connected to the outer wall of the first connecting frame 800, and a second connecting frame 802 is fixedly connected to the outer wall of the inclined plate 801.

[0051] In this embodiment, the fixing frame 8 is used to install the clamp 9, and the inclined plate 801 can facilitate the movement of the table frame 10.

[0052] Specifically, the table frame 10 includes a support leg 1000, a wheel block 1001 is fixedly connected to the bottom outer wall of the support leg 1000, a movable wheel 1002 is fixedly connected to the bottom outer wall of the wheel block 1001, a contact block 1003 is fixedly connected to the outer wall of the support leg 1000, and a contact wheel 1004 is provided on the inner wall of the contact block 1003.

[0053] In this embodiment, the table frame 10 is moved by the moving wheel 1002, and the contact wheel 1004 will reduce the stability and friction of the table frame 10 when it rotates when the contact block 1003 contacts the outer cylinder 1.

[0054] Specifically, the ground 12 includes a cement floor 1200, and the inner wall of the cement floor 1200 is provided with a limiting groove 1201.

[0055] In this embodiment, the limiting groove 1201 is circular and concentric with the outer cylinder 1, so that the distance between the table frame 10 and the outer cylinder 1 will not change when the table frame 10 rotates.

[0056] The working principle and usage process of this invention: The inner cylinder 2 can slide and rise on the inner wall of the outer cylinder 1, thus changing the height of the inner cylinder 2. Three discharge ports 203 are provided on the inner wall at the bottom of the inner cylinder 2. These three discharge ports 203 correspond to the first inlet 101, the second inlet 102, and the third inlet 103, respectively, and their heights are different. Raw materials can only be discharged when each discharge port 203 corresponds to one of these three outlets, thus adapting to different sizes and heights of casting molds. The bottom of the casting barrel 200 is a convex surface 202, which improves the discharge effect. The table frame 10 is a movable frame. The mounting base 11 on the top of the table frame 10 is used to mount the casting mold, and the casting mold can be replaced. When the table frame 10 moves onto the fixed frame 8, it presses down on the clamp 9, thereby fixing the moving wheels 1002 at the bottom of the table frame 10, preventing the table frame 10 from moving. By rotating the base 7... It can move along the limiting groove 1201 opened on the ground 12, so that it can be aligned with the first drain port 101, the second drain port 102, and the third drain port 103 at different positions. The first sealing machine 4, the second sealing machine 5, and the third sealing machine 6 are used to seal the first drain port 101, the second drain port 102, and the third drain port 103 respectively, thereby preventing raw material leakage. The motor 403 can rotate the screw 404, so that the connecting bearing 402 connected to it will drive the sealing plate 405. The sealing plate 405 is used to block the discharge port 203 during vertical movement. When the moving wheel 1002 presses against the force plate 900, the force plate 900 moves downward. Then, the two clamps 901 installed on the force plate 900 will clamp the moving wheel 1002, and the locking block 903 at the bottom of the force plate 900 will insert between the locking blocks 906 set on the hydraulic rod 904. This restricts the position of the table frame 10 and prevents it from moving arbitrarily. Activating the hydraulic rod 904 separates the locking blocks 906 and 903, allowing the locking blocks 903 to move upward without restriction. Pushing the table frame 10 will then move the table frame. Table 10 is pushed out from clamp 9. Motor 701 is mounted on base plate 700. After motor 701 rotates wheel 702, wheel 702 will move on limiting groove 1201 on ground 12. Fixture 8 is used to install clamp 9. Inclined plate 801 can facilitate the movement of table frame 10. Table frame 10 moves by moving wheel 1002. Contact wheel 1004 will reduce the stability and friction of table frame 10 when contact block 1003 contacts outer cylinder 1. Limiting groove 1201 is circular and concentric with outer cylinder 1, so that the distance between table frame 10 and outer cylinder 1 will not change when table frame 10 rotates.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
