An adjusting mechanism 7 for adjusting the tilt angle of the casting dish 6 is also provided on the bracket 5. The mold to be cast is placed in the positioning groove 2 for positioning, the sealing cover 9 on the casting dish 6 is opened, and the molten high-temperature molten iron or other melt is poured into the casting dish 6, the sealing cover 9 is closed, and the casting dish 6 is driven to move by the sliding component 4. After moving to the appropriate position, the casting dish 6 is adjusted in angle by the adjusting mechanism 7 so that the casting dish 6 can be tilted for casting. At the same time, the feeding mechanism 3 can work to assist the molten liquid to quickly and accurately enter the casting port of the mold and guide the solution at the casting port, thereby accelerating the molten liquid to enter the mold, and at the same time, the mold can vibrate slightly to further accelerate the molten liquid to enter the mold.

[0031] See also Figure 1 and Figure 2 The sliding assembly 4 includes two ear plates 401 fixedly arranged on the side wall of the casting table 1 and symmetrically arranged in front and back. A guide rod 402 is fixedly connected between the opposite side walls of the front and rear ear plates 401. A slide seat 403 with a moving wheel at the bottom is slidably arranged on the guide rod 402. The upper side of the slide seat 403 is connected to the bracket 5. The bracket 5 includes two columns 501. The lower ends of the columns 501 are fixedly connected to the upper side of the slide seat 403. An angle plate 502 is fixedly connected between the upper ends of the two columns 501. A handle with a U-shaped structure is fixedly arranged on the outer side wall of the upper end of the column 501. The casting dish 6 is supported by the bracket 5 in cooperation with the adjustment mechanism 7. There is no need for the staff to lift it. At the same time, the staff can push the bracket 5 to move to the designated position along the casting table 1 for casting with the cooperation of the slide seat 403 by the handle.

[0032] See also Figure 1 , Figure 2 , Figure 7 , Figure 8The adjusting mechanism 7 includes a rotating shaft rotatably arranged between the front sides of the upper ends of the two columns 501, a guide wheel 701 is fixedly arranged on the rotating shaft, a pulley assembly 702 is connected to the lower side of the angle plate 502, a first traction rope 703 is wound between the pulley assembly 702 and the guide wheel 701, a second traction rope 704 is also connected to the pulley assembly 702, the end of the second traction rope 704 away from the pulley assembly 702 is fixedly connected to the casting dish 6, a worm gear 705 is fixedly arranged on the end of the rotating shaft close to the handle, a worm 706 meshing with the worm gear 705 is rotatably arranged on the left side wall of the left column 501, and a rotating wheel 707 is fixedly connected to the rear end of the worm gear 706. The pulley assembly 702 includes two pulley seats, both of which are rotatably provided with two pulleys, and the upper pulley seat is fixedly connected to the angle plate 502, and the lower pulley seat is movably connected to the upper pulley seat through the first traction rope 703, one end of the first traction rope 703 close to the pulley assembly 702 is fixedly connected to any pulley, and the other end of the first traction rope 703 is fixedly connected to the guide wheel 701, and the end of the second traction rope 704 away from the casting dish 6 is fixedly connected to the lower side of the lower pulley seat.

[0033] In order to reduce the difficulty of casting, after the casting dish 6 is moved to the specified position through the sliding assembly 4, the staff only needs to control the rotation of the rotating wheel 707, and cooperate with the worm gear 705 and worm 706 to rotate the guide wheel 701, so as to drive the first traction rope 703 to be wound up. The cooperation of the upper and lower four pulleys in the pulley assembly 702 can save more effort. The pulley assembly 702 cooperates with the second traction rope 704 to more easily pull one end of the casting dish 6 to lift up, so that the liquid outlet of the casting dish 6 can gradually rotate downward to cast the mold, and in the process of continuously pouring the molten liquid, due to the locking effect of the worm gear 705 and worm 706, the staff does not need to continuously apply driving force to the rotating wheel 707. When the casting is nearing the end, it only needs to control the rotating wheel 707 to slowly reverse so that the liquid outlet of the casting dish 6 can be slowly lifted. Only one person is required to operate the whole process, and the operation is more labor-saving and safer.

[0034] See also Figure 1 and Figure 4The feeding mechanism 3 has two L-shaped vertical plates 301, which are fixedly arranged on the left and right side walls of the casting platform 1 respectively. A slide 302 is movably arranged on the upper side of the two vertical plates 301. A liquid injection pipe 303 is arranged on the slide 302. A drainage rack 304 is fixedly arranged at the lower end of the liquid injection pipe 303. The drainage rack 304 includes a connecting shaft fixedly connected to the liquid injection pipe 303. A plurality of drainage rods uniformly distributed along its circumferential direction are fixedly arranged on the side wall of the connecting shaft near the lower end. A receiving dish 305 with a funnel structure is fixedly connected to the upper end of the liquid injection pipe 303. A through hole is opened on the lower side wall of the positioning groove 2. A flat-structured toggle plate 306 for toggling the mold vibration is rotatably arranged in the through hole. A driving assembly 307 is arranged on the toggle plate 306. A driving seat 8 is arranged on the bracket 5 to cooperate with the slide 302 to drive the drainage rack 304 to insert into the casting port of the mold.

[0035] In order to improve the efficiency of mold casting, when the sliding component 4 drives the casting dish 6 to move toward the mold, the driving seat 8 can drive the slide 302 to move downward, and the slide 302 can drive the drainage rack 304 at the lower end of the injection tube 303 to be inserted into the casting port on the upper side of the mold. When the casting dish 6 is casting, the molten liquid enters the injection tube 303 through the receiving dish 305, and then enters the casting port on the upper side of the mold along the drainage rack 304. The driving component 307 can drive the toggle plate 306 to rotate. The rotation of the toggle plate 306 can cyclically touch the lower side of the mold to cause a slight vibration of the mold, thereby accelerating the movement of the molten liquid in the mold. At the same time, the molten liquid in the injection tube 303 can be diverted into the inner cavity of the mold along the drainage rack 304 to avoid the molten liquid instantly filling the casting port and hindering the discharge of air inside the mold.

[0036] See also Figure 3 , Figure 4 , Figure 5 and Figure 6The slide 302 includes two slide posts 3021 with an inverted T-shaped structure. A slide hole is opened on the surface of the vertical section of the vertical plate 301 near the upper side. The lower end of the slide post 3021 is slidably set in the slide hole, and a spring 3022 is fixedly connected between the lower inner wall of the slide hole and the lower end of the slide post 3021. The upper ends of the two slide posts 3021 both pass through the corresponding slide holes and are fixedly connected to a connecting seat 3023 with a triangular structure. The injection tube 303 is fixedly set on the connecting seat 3023, and the left and right sides of the connecting seat 3023 are fixedly connected to guide seats 3024 with a triangular structure. A plurality of first guide rollers are rotatably provided on the lower side of the driving seat 8. The first guide rollers roll against the sloped surface of the guiding seat 3024 to reduce the friction when the two are in contact. A front-to-back symmetrical diagonal support column 3025 is fixedly provided on the lower side of the guiding seat 3024. A second guide roller is rotatably provided on one end of the diagonal support column 3025 close to the vertical plate 301. The second guide roller rolls against the side close to the corresponding vertical plate 301. While supporting the guiding seat 3024, the friction between the diagonal support column 3025 and the side wall of the vertical plate 301 can be reduced. Before casting, the driving seat 8 moves synchronously with the casting dish 6, and the driving seat 8 will come into contact with the sloped surface of the guiding seat 3024 in advance, so that the guiding seat 3024 is gradually moved downward under pressure, and the drainage rack 304 originally located above the casting port of the mold is gradually inserted into the casting port, which plays a role in guiding the molten liquid.

[0037] See also Figure 5 and Figure 6 The driving assembly 307 includes a driving shaft 3072 rotatably arranged on the horizontal section of the left vertical plate 301. The surface of the driving shaft 3072 near the lower end is connected to the left end of the toggle plate 306 through a bevel gear set 3073. A driving motor 3071 is fixedly arranged on the left wall of the casting table 1. The output shaft of the driving motor 3071 is fixedly connected to the lower end of the driving shaft 3072. The driving motor 3071 controls the driving shaft 3072 to rotate, and the toggle plate 306 rotates under the cooperation of the bevel gear set 3073.

[0038] During the specific operation, the mold to be cast is placed in the positioning groove 2 for positioning, the sealing cover 9 on the casting dish 6 is opened, and the high-temperature molten iron or other molten liquid after the steel is melted is poured into the casting dish 6 through the external melting equipment, and the sealing cover 9 is closed. The staff pushes the bracket 5 to move, and then drives the casting dish 6 to move through the sliding assembly 4. After moving to the appropriate position, the driving seat 8 will cooperate with the guide seat 3024 to move the slide 302 downward, so that the drainage frame 304 is inserted into the casting port on the upper side of the mold, and then the rotating wheel 707 is controlled to rotate, and the sliding assembly 4 and the guide wheel 4 are moved. With the cooperation of 701, the casting dish 6 is rotated to a suitable angle, so that the molten iron flows out from the liquid outlet of the casting dish 6 and pours into the receiving dish 305 below. The molten liquid flows into the injection pipe 303 along the receiving dish 305 and finally flows into the casting port and enters the mold. At the same time, the driving component 307 in the feeding mechanism 3 can work to drive the toggle plate 306 to rotate. The rotating toggle plate 306 contacts the lower side of the mold in a cycle, so that the mold can vibrate slightly, further accelerating the molten liquid to enter the mold. When the casting is about to end, the rotating wheel 707 is controlled to slowly reverse, so that the liquid outlet of the casting dish 6 is slowly lifted. In this way, multiple molds on the casting table 1 are cast in a cycle.
