[0002] In the production process of alloy rods, various metal elements or non-metallic materials are placed in a smelting furnace to be smelted into a metal liquid.

[0034] (4) The degassing mechanism is arranged, when the rotating disc moves to the upper region of the molten metal liquid, the degassing mechanism can control the plug plate to extend into the graphite rotor, at this time, the inert gas can only enter the graphite rotor through the through hole on the plug plate, so that the gas output of the rotating disc is reduced; on the one hand, the splashing of the metal liquid due to the excessive gas output can be avoided, and on the other hand, the waste of the inert gas can be reduced; when the rotating disc moves downward to the lower region of the metal liquid, the plug plate is controlled to retract into the adapter pipe, so that the gas output of the rotating disc is increased;

DETAILED DESCRIPTION

[0050] In order to make the objects, features and advantages of the present application more clear, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing specific embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0052] Referring to Figure 1 and Figure 2 The present application provides an alloy rod casting forming device, comprising a smelting mechanism 1 for heating and melting metal or non-metal. The smelting mechanism 1 comprises a smelting furnace 101 and a first linear actuator 104. The smelting furnace 101 can be an intermediate frequency furnace, and the first linear actuator 104 can be a pneumatic cylinder or an oil cylinder. The smelting furnace 101 is provided with a nozzle 102, and the outer wall of the smelting furnace 101 is rotatably connected to the upper end of a support frame 106 through a rotating plate 105. The output end of the first linear actuator 104 is rotatably connected to the rotating plate 105. The end of the first linear actuator 104 away from the rotating plate 105 is rotatably connected to a bottom plate 103. The bottom end of the support frame 106 is also mounted on the bottom plate 103, and the bottom of the smelting furnace 101 is a certain distance from the bottom plate 103. It should be noted that the support frame 106 and the first linear actuator 104 are in pairs, and are symmetrically arranged on both sides of the smelting furnace 101. When the output end of the first linear actuator 104 is extended, the smelting furnace 101 can be driven to change from a vertical state to an inclined state, so that the molten metal in the smelting furnace 101 is discharged through the nozzle 102.

[0053] In the present embodiment, the number of smelting furnaces 101 is two, and the two smelting furnaces 101 work simultaneously, which is beneficial to improve the production efficiency.

[0054] Referring to Figure 1 and Figure 3The present application further provides a covering mechanism 2, which comprises a rotary smoke cover base 201 designed in a rectangular frame shape. A first linear guide rail 205 is mounted on the inner side of the rotary smoke cover base 201, and a first sliding block 204 is slidingly fitted on the first linear guide rail 205. The first sliding block 204 is mounted on the side of a smoke cover connecting base 203. A second linear driver 202 is mounted on the bottom of the rotary smoke cover base 201, and the output end of the second linear driver 202 is connected with the smoke cover connecting base 203. A speed reducer is further mounted on the smoke cover connecting base 203, the input end of the speed reducer is connected with a first rotary motor 206, the output end of the speed reducer is connected with a smoke cover rotary shaft 207, and the end of the smoke cover rotary shaft 207 away from the speed reducer is connected with a smoke cover 208. In addition, a pipeline for passing nitrogen or argon is arranged on the smoke cover 208. The second linear driver 202 can be a pneumatic cylinder, an oil cylinder, an electric telescopic rod or an electric push rod, preferably an electric telescopic rod. When the first rotary motor 206 drives the smoke cover 208 to rotate to the top of the smelting furnace 101, the rotary smoke cover base 201 is driven to move up and down by the second linear driver 202, so that the smoke cover 208 is covered on the smelting furnace 101. At this time, the pipeline on the smoke cover 208 is used to fill nitrogen or argon into the smelting furnace 101, so that the oxygen in the smelting furnace 101 is discharged, and oxidation of the material during melting is prevented.

[0055] It should be noted that the covering mechanism 2 corresponds to the smelting furnace 101 one by one. During the process of filling nitrogen or argon into the smelting furnace 101 through the pipeline on the smoke cover 208, the gas in the smelting furnace 101 is continuously discharged outward through the tuyere 102. In addition, the present application further provides a smoke collection cover located above the alloy bar casting forming device of the present application, which plays a role in collecting smoke and avoiding workers working in a smoke environment.

[0056] Please refer to Figure 1 and Figure 4The application also provides a degassing mechanism 3, which comprises a degassing mechanism suspension arm 309, a graphite rotor 313 is rotatably connected to the degassing mechanism suspension arm 309, and a rotating disc 314 is arranged at the bottom end of the graphite rotor 313, and the bottom or side of the rotating disc 314 is provided with a gas outlet hole or a gas outlet channel. The degassing mechanism suspension arm 309 can move up and down and reciprocate under the action of an external force, so that the rotating disc 314 extends into or out of the corresponding molten metal of the smelting mechanism 1. Specifically, the degassing mechanism 3 further comprises a degassing mechanism base 301, and the degassing mechanism base 301 is rotatably connected with a degassing mechanism vertical seat 302. A degassing mechanism top plate 303 is arranged at the top end of the degassing mechanism vertical seat 302, a second rotary motor 304 is arranged on the side wall of the degassing mechanism vertical seat 302, and the degassing mechanism suspension arm 309 is slidingly fitted on the side wall of the degassing mechanism vertical seat 302. The second rotary motor 304 is used to drive a first synchronous wheel 305 to rotate, the first synchronous wheel 305 drives a second synchronous wheel 307 to rotate through a synchronous belt 306, and the synchronous belt 306 is connected with one end of the degassing mechanism suspension arm 309. Therefore, when the first synchronous wheel 305 is in driving connection with the second synchronous wheel 307 through the synchronous belt 306, the degassing mechanism suspension arm 309 will move up and down along the height direction of the degassing mechanism base 301. In addition, in order to realize the reciprocating swing of the degassing mechanism suspension arm 309 within a certain angle range, so as to realize the movement of the degassing mechanism 3 to the directly above of the smelting furnace 101, the degassing mechanism vertical seat 302 can be driven to rotate through a power mechanism, and the power mechanism can be a driving motor directly connected with the bottom end of the degassing mechanism vertical seat 302, or the driving motor drives the degassing mechanism vertical seat 302 to rotate through a transmission mechanism, which can be determined by the person skilled in the art according to the actual situation, and the application does not make specific limitation; wherein the power mechanism is not shown in the figure.

[0057] Please refer to Figure 5 and Figure 6, graphite rotor 313 top end extends into the degassing machine cantilever 309 after the installation of the second sealing block 322, the degassing machine cantilever 309 is also installed with the adapter pipe 317. The bottom end of the adapter pipe 317 is slidingly fitted with the first sealing block 320 abutting the second sealing block 322, and the inner circle of the first sealing block 320 is provided with a sealing ring 321, and the inner circle of the sealing ring 321 is in contact with the outer surface of the adapter pipe 317. The first sealing block 320 and the second sealing block 322 can be made of silicon carbide, and the sealing ring 321 can be made of O-shaped rubber sealing ring. Silicon carbide has the characteristics of wear resistance and small friction. The outer surface of the adapter pipe 317 is sleeved with a spring 319 and clamped with a clamping ring 318, and the two ends of the spring 319 are respectively abutted with the clamping ring 318 and the first sealing block 320. Under the action of the elastic force of the spring 319, the first sealing block 320 and the second sealing block 322 are tightly fitted, which plays a good sealing effect, and at the same time, the second sealing block 322 can rotate relative to the first sealing block 320, so that the graphite rotor 313 can rotate relative to the adapter pipe 317. In order to realize the rotation of the graphite rotor 313, the third rotary motor 310 is installed on the top wall of the degassing machine cantilever 309, and the third rotary motor 310 drives the graphite rotor 313 to rotate through a transmission mechanism.

[0058] Optionally, the side wall of the adapter pipe 317 is connected with the gas conveying pipe 323, and the other end of the gas conveying pipe 323 is connected with the gas source. The gas source can be a nitrogen source or an argon source, preferably an argon source. As described above, the power mechanism can move the degassing mechanism 3 directly above the smelting furnace 101, at this time, the second rotary motor 304 is started, the degassing machine cantilever 309 is driven to move downward through the synchronous belt 306, so that the rotating disc 314 enters the molten metal of the smelting furnace 101, and then drives the rotating disc 314 to reciprocate up and down in the molten metal. On the one hand, it can pass nitrogen or argon to the molten metal, on the other hand, the rotating disc 314 stirs the molten metal, breaks the inert gas bubbles into very fine small bubbles, and makes them uniformly dispersed in the molten metal. By reducing the bubble diameter, the total surface area of these bubbles increases sharply, which makes more inert bubble surfaces contact with the oxygen in the molten metal to carry the oxygen in the molten metal to the liquid surface, thereby achieving the purpose of further removing oxygen.

[0059] Preferably, the top wall of the degassing machine cantilever 309 is provided with a third linear actuator 315, and the output end of the third linear actuator 315 is provided with a baffle plate 316, and a plurality of through holes 3161 are formed in the baffle plate 316. When the rotating disc 314 moves to the upper region of the molten metal corresponding to the smelting furnace 101, the third linear actuator 315 drives the baffle plate 316 to extend into the graphite rotor 313, and the outer surface of the baffle plate 316 is attached to the inner wall of the graphite rotor 313. When the baffle plate 316 extends into the graphite rotor 313, the inert gas can only enter the graphite rotor 313 through the through holes 3161 on the baffle plate 316, thereby reducing the gas output of the rotating disc 314. Since the gas output of the rotating disc 314 is reduced when the rotating disc 314 moves to the upper region of the molten metal, on the one hand, it can avoid the molten metal from splashing due to excessive gas output, and on the other hand, it can reduce the waste of inert gas. Conversely, when the rotating disc 314 moves to the lower region of the molten metal, the baffle plate 316 is retracted into the adapter pipe 317 at this time, thereby increasing the gas output of the rotating disc 314. The lower surface of the degassing machine top plate 303 is provided with a distance sensor 308, preferably an ultrasonic distance sensor, and the distance sensor 308 is used to monitor the distance from the degassing machine cantilever 309; when the distance sensor 308 monitors that the distance from the degassing machine cantilever 309 is greater than the preset distance, the third linear actuator 315 is controlled to retract the baffle plate 316 into the adapter pipe 317; otherwise, when the distance sensor 308 monitors that the distance from the degassing machine cantilever 309 is less than the preset distance, the third linear actuator 315 is controlled to extend the baffle plate 316 into the graphite rotor 313.

[0060] Optionally, the lower surface of the degassing machine cantilever 309 is fixedly connected with a baffle plate 312 through a first connecting plate 311, and the middle part of the graphite rotor 313 is rotatably connected with the baffle plate 312. The baffle plate 312 can make the graphite rotor 313 rotate more stably, and can further prevent the molten metal from splashing.

[0061] Please refer to Figure 1 and Figure 7 The present application also provides a transfer mechanism 4, which comprises a casting crucible 421 and an electronic scale 413. The electronic scale 413 is used to accurately measure the weight of the molten metal received by the casting crucible 421, so as to control the quality of the finished alloy rod. The transfer mechanism 4 is used to transfer the casting crucible 421 to the corresponding casting position of the casting mechanism 5, and pour the received molten metal into the mold 510.

[0062] The transfer mechanism 4 comprises a first moving mechanism, a second moving mechanism, a lifting mechanism and a tilting mechanism. The first moving mechanism comprises a fixed track 401 extending from the smelting furnace 101 to the casting mechanism 5. The fixed track 401 is rollingly fitted with first driving wheels 405, two of which are installed on the same transversely rotating shaft 404, and the corresponding transversely rotating shaft 404 of the first driving wheels 405 is rotationally connected to a moving track 406. The corresponding transversely rotating shaft 404 of one set of the first driving wheels 405 is connected to the output end of a fourth rotating motor 402 through a first transmission mechanism 403. The first transmission mechanism 403 can be a bevel gear transmission structure or a worm gear transmission structure, preferably a worm gear transmission mechanism. Thus, when the fourth rotating motor 402 is started, the fourth rotating motor 402 will drive the first driving wheels 405 to rotate, thereby moving the moving track 406 along the fixed track 401. The second moving mechanism comprises two transverse guide rails 407 installed on the moving track 406, and the transverse guide rails 407 are rollingly fitted with second driving wheels 411 installed on a longitudinal driving shaft 410. The longitudinal driving shaft 410 is connected to the output end of a fifth rotating motor 409 at one end, and the longitudinal driving shaft 410 is rotationally connected to a weighing base 408. Thus, when the fifth rotating motor 409 is started, the second driving wheels 411 will be driven to rotate, so that the weighing base 408 moves along the transverse guide rails 407. The weighing base 408 is provided with an electronic scale 413, and the electronic scale 413 is provided with an electronic scale guard 412 outside.

[0063] Further, the lifting mechanism comprises two lifting rail frames 423 arranged at intervals, the bottom end of the lifting rail frame 423 is mounted on the electronic scale 413, the lifting rail frame 423 is slidably connected with the ladle support frame 419 through the second linear guide rail 422, and the pouring mechanism is arranged on the two ladle support frames 419. One of the ladle support frames 419 is threadedly connected with the lead screw 417, and the other ladle support frame 419 is slidably connected with the sliding rod 418. The bottom end of the lead screw 417 is connected with the lifting machine linkage shaft 416 through the second transmission mechanism 415, and the lifting machine linkage shaft 416 is connected with the output end of the sixth rotary motor 414. Therefore, after the sixth rotary motor 414 is started, the ladle support frame 419 will slide up and down along the second linear guide rail 422, thereby driving the pouring mechanism to slide up and down along the second linear guide rail 422. The second transmission mechanism 415 at the bottom end of the lead screw 417 can be a bevel gear transmission structure or a worm gear transmission structure; preferably, the second transmission mechanism 415 at the bottom end of the lead screw 417 is a worm gear transmission structure. In addition, the pouring mechanism comprises a seventh rotary motor 420, and the output shaft of the seventh rotary motor 420 is provided with a casting crucible 421 in the middle, which is used to receive the molten metal liquid poured out of the smelting furnace 101. Therefore, the first moving mechanism can drive the casting crucible 421 to move and transfer between the smelting mechanism 1 and the casting mechanism 5, and the molten metal liquid melted by the smelting mechanism 1 is transferred to the casting mechanism 5 for casting and forming; the second moving mechanism can drive the casting crucible 421 to approach or move away from the smelting furnace 101 to adapt to the discharge of the smelting furnace 101. Since the pouring angle of the smelting furnace 101 changes during the pouring process, the falling point of the metal liquid in the casting crucible 421 will change, and the second moving mechanism can ensure that the metal liquid falls into the casting crucible 421; the lifting mechanism is used to drive the casting crucible 421 to move up and down, thereby reducing the difference and reducing the splashing of the alloy liquid.

[0064] Please refer to Figure 1 、 Figure 8 and Figure 9The casting mechanism 5 comprises a rotating frame and a mold opening and closing mechanism. The rotating frame comprises a slewing bearing 502, the inner ring of which is driven to rotate by an external force, a mold mounting cylinder 503 is mounted on the inner ring of the slewing bearing 502, and the outer ring of the slewing bearing 502 is mounted on a disc base 501. The mold mounting cylinder 503 is mounted with a mold mounting disc 504. The mold opening and closing mechanism comprises a fourth linear actuator 506, which is rotationally connected to the outer wall of the mold mounting cylinder 503. A fixed column one 505 is mounted on the lower surface of the mold mounting disc 504. The output end of the fourth linear actuator 506 is rotationally connected to one end of a connecting rod one 507. The middle part of the connecting rod one 507 is rotationally connected to the fixed column one 505. The end of the connecting rod one 507 away from the fourth linear actuator 506 is connected to a mold cover 509. It should be noted that the fourth linear actuator 506 can be a pneumatic cylinder or an oil cylinder or an electric telescopic rod. Preferably, the fourth linear actuator 506 is a pneumatic cylinder. By controlling the extension and retraction of the fourth linear actuator 506, the mold cover 509 can be driven to approach or move away from the bottom of the mold 510, thereby achieving the closing and separation of the mold cover 509 and the mold 510, and making the mold opening and closing operation convenient.

[0065] Preferably, the mold cover 509 is rotationally connected to one end of the connecting rod one 507 through a fixed seat. The end of the connecting rod one 507 close to the mold cover 509 and the side close to the mold cover 509 are provided with a stepped portion 5071. The stepped portion 5071 is inclinedly arranged so that the surface of the stepped portion 5071 gradually moves away from the mold cover 509. A jackscrew 508 is screwed at the end of the stepped portion 5071 away from the mold cover 509. The extension length of the jackscrew 508 can be adjusted by rotating the jackscrew 508. It should be noted that the end of the jackscrew 508 is a certain distance away from the surface of the mold cover 509, and the surface of the stepped portion 5071 away from the end of the jackscrew 508 is also a certain distance away from the surface of the mold cover 509, so that the mold cover 509 has a certain rotational freedom relative to the connecting rod one 507. Therefore, even if the bottom of the mold 510 is not in a horizontal state, the mold cover 509 can be automatically aligned with the bottom surface of the mold 510 during the closing process due to the certain rotational freedom of the mold cover 509. After the mold is opened, the mold cover 509 will be rotated to an approximately vertical state. The mold cover 509 not only does not interfere with the downward falling of the cast alloy bar, but also rotates to a vertical state when the alloy bar falls on the mold cover 509, so that the mold cover 509 also plays a certain guiding role.

[0066] In order to avoid the adhesion between the cast alloy bar and the mold 510 after casting, please refer to Figure 1 and Figure 10The present application is provided with a spray release agent mechanism 6 for spraying release agent into the mold 510 after the mold is closed, so that the release agent forms a release layer under the action of the poured high-temperature metal liquid, thereby facilitating smooth release of the alloy bar; the release agent can be liquid grease. Specifically, the spray release agent mechanism 6 includes a spray release agent support 601, a fifth linear actuator 603 and a liquid storage barrel 602 are installed on the spray release agent support 601, the liquid storage barrel 602 is used to store release agent, and the liquid storage barrel 602 is connected with the spray head 608 through the liquid delivery pipe 604. The output end of the fifth linear actuator 603 is fixedly connected with the second connecting plate 605, one end of the second connecting plate 605 is fixedly connected with the connecting rod 606, the bottom end of the connecting rod 606 is connected with the mounting plate 607, and the spray head 608 is mounted on the mounting plate 607. Therefore, when the output end of the fifth linear actuator 603 is telescopic, the spray head 608 can be brought into or out of the mold 510, and the liquid grease stored in the liquid storage barrel 602 can be sprayed on the inner surface of the mold 510 by the spray head 608.

[0067] It should be noted that during the process of spraying release agent on the inner surface of the mold 510, a small amount of release agent will penetrate into the mold surface between the bottom of the mold 510 and the mold cover 509, and under the action of the high-temperature metal liquid, the release agent cannot be completely burned, resulting in the formation of mud on the mold surface; the mud formed by the release agent that has not completely burned will cause the mold surface to not fit tightly enough during the subsequent mold closing process, thereby causing the alloy bar surface to produce burrs, and further affecting the product yield. Therefore, please refer to Figure 1 and Figure 11The mold closing surface polishing mechanism 7 is used for polishing the bottom of the mold 510 and the surface of the mold cover 509 to clean the mud formed by the incomplete combustion of the release agent.

[0068] It should be noted that the steel wire brush has a thin steel wire with certain elasticity, so as to adapt to the bottom of each mold 510.

[0069] In some preferred embodiments, as shown in Figure 12 The seventh linear driver 709 is rotatably connected to the mold closing surface cleaning connecting frame 706, the second fixed column 711 is fixedly connected to the mold closing surface cleaning connecting frame 706, the bottom end of the second fixed column 711 is rotatably connected to the middle part of the second connecting rod 710, the output end of the seventh linear driver 709 is rotatably connected to one end of the second connecting rod 710, and the other end of the second connecting rod 710 is connected to the outer surface of the eighth rotary motor 707. In this way, by controlling the extension and retraction of the output end of the seventh linear driver 709, the steel wire brush on the same polishing disc 708 can be sequentially in contact with the surface of the mold 510 and the mold cover 509, so that the eighth rotary motor 707 and the polishing disc 708 corresponding to the mold 510 and the mold cover 509 do not need to be set.

[0070] Please refer to Figure 1 and Figure 13In order to eject the solidified alloy bar from the mold 510 after the mold opening operation is completed, and catch the alloy bar after the mold opening, the present application is provided with a mold opening and catching mechanism 8. The mold opening and catching mechanism 8 includes a hammering mechanism and a catching mechanism. The hammering mechanism includes a hammering support 801, and the hammering support 801 is provided with an eighth linear actuator 802, and the output end of the eighth linear actuator 802 is fixedly connected with a hammering head. The catching mechanism includes a catching support 803, and the catching support 803 is provided with a catching channel 804 in the middle, and the front end of the catching channel 804 is an inclined material receiving pipe, and the rear end of the catching channel 804 is a material receiving groove, and the two sides of the material receiving groove are provided with ninth linear actuators 805, and the output end of the ninth linear actuator 805 is fixedly connected with a catching baffle 806, and the spacing between the catching baffles 806 on the two sides of the material receiving groove gradually narrows. When the mold mounting disc 504 drives the mold 510 to rotate to the mold opening position, the fourth linear actuator 506 rotates the mold cover 509 to an approximately vertical state, at this time the eighth linear actuator 802 drives the hammering head to move downward, and the hammering head ejects the cast alloy bar, under the guidance of the mold cover 509, the alloy bar falls into the material receiving pipe, and then under the guidance of the catching baffle 806, the alloy bar slides to the end of the material receiving groove; since the material receiving groove is open, it is convenient for the corresponding mechanical arm in the subsequent process to grasp the alloy bar.

[0071] The present application also provides a molding method of an alloy bar casting molding device, which is realized by the above-mentioned device,

[0072] The method comprises the following steps:

[0073] Step S101, heating and melting metal or non-metal by the melting mechanism 1 to obtain molten metal liquid;

[0074] Step S102, pouring the molten metal liquid into the casting crucible 421 of the transfer mechanism 4, and accurately measuring the weight of the metal liquid received by the casting crucible 421 by the electronic scale 413;

[0075] It should be noted that during the pouring of the molten metal liquid, the second moving mechanism drives the casting crucible 421 to approach or move away from the melting furnace 101 to adapt to the change of the inclination angle of the melting furnace 101 during the pouring process, so that when the falling point of the metal liquid into the casting crucible 421 changes, the metal liquid can still fall into the casting crucible 421; the lifting mechanism drives the casting crucible 421 to move up and down to reduce the difference and reduce the splashing of the alloy liquid.

[0076] Step S103, transferring the casting crucible 421 to a position corresponding to the casting position of the casting mechanism 5 by the transfer mechanism 4;

[0077] Similarly, by driving the pouring crucible 421 to approach or move away from the mold 510 through the second moving mechanism, the change of the falling point of the metal liquid in the mold 510 can be adapted to the change of the pouring angle of the pouring crucible 421 during the pouring process, so that the metal liquid can still fall into the mold 510.

[0078] Step S104, the mold cover 509 and the bottom end of the mold 510 are driven to be folded to each other by the mold opening and closing mechanism.

[0079] It should be noted that the mold opening and closing mechanism includes a fourth linear driver 506, and the output end of the fourth linear driver 506 is rotationally connected to one end of a connecting rod 507, the middle part of the connecting rod 507 is rotationally connected to a fixed column 505, and the end of the connecting rod 507 away from the fourth linear driver 506 is connected to the mold cover 509. The mold cover 509 has a certain rotational freedom relative to the connecting rod 507; therefore, even if the bottom of the mold 510 is not in a horizontal state, during the mold closing process, the mold cover 509 can also be automatically aligned with the bottom surface of the mold 510 due to the certain rotational freedom.

[0080] Step S105, the mold 510 after being closed is sprayed with a mold release agent by the mold release agent spraying mechanism 6; wherein the mold release agent can be a liquid grease, and the mold release agent forms a mold release layer under the action of the high-temperature metal liquid poured in, so as to facilitate the smooth demolding of the alloy bar.

[0081] Step S106, each mold 510 after being closed is sequentially rotated to a pouring position;

[0082] Step S107, the metal liquid in the pouring crucible 421 is transferred to the mold 510, and the mold release agent is changed into a mold release layer under the action of the metal liquid;

[0083] Step S108, each mold 510 after being closed is sequentially rotated to a demolding position, the solidified alloy bar is ejected from the mold 510 after being opened by the demolding spool mechanism 8, and the alloy bar after being demolded is caught;

[0084] Step S109, the mold 510 after being opened and the surface of the mold cover 509 are polished by the mold surface polishing mechanism 7, so as to clean the dirt formed by the mold release agent which is not completely combusted.

[0085] It should be noted that in the process of spraying the release agent on the inner surface of the mold 510, a small amount of release agent will penetrate into the mold closing surface between the bottom of the mold 510 and the mold cover 509. Under the action of high-temperature molten metal, the release agent cannot be completely burned, resulting in the formation of mud on the mold closing surface. The mud formed by the incomplete combustion of the release agent will cause the mold closing surface to not fit tightly enough during the subsequent mold closing process, thereby causing the formation of burrs on the surface of the alloy bar, and further affecting the qualification rate of the product. Therefore, cleaning the mud formed by the incomplete combustion of the release agent by the mold closing surface polishing mechanism 7 can ensure that the bottom of the mold 510 and the surface of the mold cover 509 fit tightly.
