Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of artificial joint production equipment, and specifically relate to an artificial joint casting device. Background Art

[0002] An artificial joint is a substitute for a damaged joint in the human body. It is usually formed by casting in a rapid melting furnace and then performing fine processing. For example, the artificial joint casting device disclosed in Chinese Patent Application No. CN202020506593.X has the following specific content: The centrifugal turntable is of ferromagnetic structure, and the fixing component further includes a magnet. The magnet is arranged on the support plate and is used to adsorb the support plate on the centrifugal turntable to facilitate the installation, disassembly and replacement of the fixing cylinder. It has the following technical problems:

[0003] The fixing cylinder is limited by the magnetic attraction generated between the magnet and the centrifugal turntable. When the driving component drives the centrifugal turntable to rotate, it is difficult for the fixing cylinder to be firmly fixed on the centrifugal turntable, so that when the centrifugal turntable rotates, the fixing cylinder is likely to fall off the centrifugal turntable. Summary of the Utility Model

[0004] Therefore, the embodiments of the present utility model provide an artificial joint casting device to solve the problem that the fixing cylinder in the prior art is likely to fall off the centrifugal turntable.

[0005] In order to achieve the above purpose, the embodiments of the present utility model provide the following technical solutions:

[0006] An artificial joint casting device includes a fixing cylinder and a protective cylinder for limiting the fixing cylinder.

[0007] The fixing cylinder includes a casting cylinder for casting an artificial joint. A cross key is installed at the bottom end of the casting cylinder, and a locking component for facilitating the locking of the casting cylinder is installed at the lower end of the casting cylinder.

[0008] The protective cylinder includes a cylinder body. A limiting turntable for supporting the casting cylinder is installed inside the cylinder body, and a motor for controlling the rotation of the limiting turntable is installed at the lower end of the limiting turntable.

[0009] The limiting turntable includes a limiting pipe column and an arc-shaped elastic piece for cooperating with the locking component to lock the casting cylinder.

[0010] Further, a pouring port for pouring liquid material into the inside of the casting cylinder is installed at the upper end of the casting cylinder. A fixing ring is installed in the middle of the fixing cylinder. A plurality of vertical grooves for limiting the locking component are opened at the lower end of the fixing cylinder. A spring for pushing the locking component downward is installed at the lower end of the fixing ring.

[0011] Further, insertion holes are formed in the edges of the cross key for limiting the casting cylinder in cooperation with the limiting pipe column and the arc-shaped elastic sheet.

[0012] Further, the locking assembly includes a limiting ring, and a plurality of sliders for limiting the limiting ring in cooperation with the vertical grooves are installed on the inner wall of the limiting ring.

[0013] Further, a plurality of conical pressing blocks for controlling the deformation of the arc-shaped elastic sheet are installed at the bottom end of the limiting ring, and a handle for easily lifting the limiting ring upward is installed on the outer wall of the limiting ring.

[0014] Further, a sealing cover is installed at the top end of the cylinder body, an air inlet interface is installed at the upper end of the cylinder body, and an air outlet interface is installed at the lower end of the cylinder body.

[0015] Further, a key groove for placing the cross key is formed in the middle of the limiting turntable.

[0016] The embodiments of the present invention have the following advantages:

[0017] Through the arc-shaped elastic sheet fixedly installed on the limiting pipe column, when the cross key is inserted into the cavity of the key groove, the limiting pipe column and the arc-shaped elastic sheet synchronously pass through the cavity of the insertion hole, and the spring pushes the locking assembly, so that the limiting ring drives the conical pressing block to insert into the middle of the plurality of conical pressing blocks. The conical pressing block squeezes the upper end of the arc-shaped elastic sheet, causing the upper end of the arc-shaped elastic sheet to deform. The outer wall of the arc-shaped elastic sheet is in tight contact with the inner wall of the cavity of the insertion hole, avoiding loosening of the casting cylinder when the motor drives the limiting turntable to rotate, so that when the limiting turntable rotates, the casting cylinder rotates synchronously.

[0029] Please refer to Figures 1 - 5 , the present utility model provides an artificial joint casting device, including a fixed cylinder 100 and a protective cylinder 200 for limiting the fixed cylinder 100.

[0030] The fixed cylinder 100 includes a casting cylinder 110 for casting an artificial joint. A pouring port 111 for pouring liquid material into the interior of the casting cylinder 110 is fixedly installed at the upper end of the casting cylinder 110. A fixing ring 112 is fixedly installed in the middle of the fixed cylinder 100. The fixing ring 112 is used to limit the spring 140, so that the spring 140 pushes the locking assembly 130 downward. A plurality of vertical grooves 113 for limiting the locking assembly 130 are formed at the lower end of the fixed cylinder 100, and the slider 132 slides in the cavity of the vertical groove 113.

[0031] A cross key 120 is fixedly installed at the bottom end of the casting cylinder 110. A jack 121 for cooperating with the limiting pipe column 222 and the arc-shaped elastic piece 223 to limit the casting cylinder 110 is formed at the edge of the cross key 120. When the casting cylinder 110 is placed on the upper end of the limiting turntable 220, the cross key 120 is placed in the cavity of the key groove 221, so that the limiting pipe column 222 and the arc-shaped elastic piece 223 are inserted into the cavity of the jack 121, thereby limiting the casting cylinder 110. When the limiting turntable 220 rotates, the casting cylinder 110 can be driven to rotate synchronously.

[0032] A locking assembly 130 for facilitating the locking of the casting cylinder 110 is movably installed at the lower end of the casting cylinder 110. The locking assembly 130 includes a limiting ring 131. A plurality of sliders 132 for cooperating with the vertical groove 113 to limit the limiting ring 131 are fixedly installed on the inner wall of the limiting ring 131, so that the limiting ring 131 can only slide up and down at the lower end of the casting cylinder 110.

[0033] A plurality of conical pressing blocks 133 for controlling the deformation of the arc-shaped elastic piece 223 are fixedly installed at the bottom end of the limiting ring 131. A plurality of arc-shaped elastic pieces 223 are installed at the upper end of the limiting pipe column 222. When the limiting ring 131 approaches the cross key 120, the conical pressing blocks 133 are inserted into the middle of the plurality of arc-shaped elastic pieces 223, driving the upper end of the arc-shaped elastic piece 223 to expand outward, so that the expanded arc-shaped elastic piece 223 is not easily separated from the cavity of the jack 121. A handle 134 for facilitating the upward lifting of the limiting ring 131 is fixedly installed on the outer wall of the limiting ring 131. A spring 140 for pushing the locking assembly 130 downward is installed at the lower end of the fixing ring 112, and the spring 140 is located at the lower end of the fixing ring 112 and the upper end of the locking assembly 130.

[0034] The protective cylinder 200 includes a cylinder body 210. A sealing cover 211 for closing the cylinder body 210 is installed at the top end of the cylinder body 210. An air inlet interface 212 is fixedly installed at the upper end of the cylinder body 210. An air outlet interface 213 is fixedly installed at the lower end of the cylinder body 210.

[0035] Inside the cylinder body 210, a limit turntable 220 for supporting the casting cylinder 110 is installed. A keyway 221 for placing the cross key 120 is provided in the middle of the limit turntable 220. The limit turntable 220 includes a limit pipe column 222 and an arc-shaped elastic piece 223 for cooperating with the locking assembly 130 to lock the casting cylinder 110, and the limit pipe column 222 and the arc-shaped elastic piece 223 are located at the four sides of the cavity of the keyway 221.

[0036] A motor 230 for controlling the rotation of the limit turntable 220 is installed at the lower end of the limit turntable 220. After the motor 230 is started, it drives the limit turntable 220 to rotate synchronously. The limit turntable 220 drives the casting cylinder 110 to rotate. A melting ladle 240 for feeding liquid materials into the casting cylinder 110 is installed inside the cylinder body 210.

[0037] The limit pipe column 222 is fixedly installed at the bottom of the cavity of the keyway 221. The arc-shaped elastic piece 223 is fixedly installed at the upper end of the limit pipe column 222, and a plurality of arc-shaped elastic pieces 223 are fixedly installed at the upper end of each limit pipe column 222. The plurality of arc-shaped elastic pieces 223 are assembled into a pipe body. When the conical pressing block 133 is inserted into the middle of the plurality of arc-shaped elastic pieces 223, the conical pressing block 133 squeezes the upper end of the arc-shaped elastic piece 223, causing the upper end of the arc-shaped elastic piece 223 to deform. The outer wall of the arc-shaped elastic piece 223 is in tight contact with the inner wall of the hole cavity of the jack 121, preventing the casting cylinder 110 from loosening when the limit turntable 220 rotates, so that the casting cylinder 110 rotates synchronously when the limit turntable 220 rotates.

[0038] Although the present invention has been described in detail with general descriptions and specific embodiments above, on the basis of the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
