The third gear 31 is fixedly sleeved on the end of the output shaft of the motor 27 and is meshed with the second gear 30 located on the upper side.

[0044] The vibration mechanism includes a support frame 32, a support rod 33, a second tension spring 34, a hammer 35 and a roller 36. The support frame 32 is vertically fixedly installed on the upper side of the bottom of the base 1. The hammer 35 is rotatably installed in the support frame 32 through the support rod 33. The second tension spring 34 is vertically arranged, and the upper and lower ends are respectively fixedly connected to the bottom side of the tail end of the hammer 35 and the upper side of the bottom of the base 1.

A plurality of first inclined platforms 37 are fixedly installed on the bottom surface of the bottom mold 3, and the plurality of first inclined platforms 37 are evenly distributed in a ring shape.

[0045] The limiting mechanism includes a bracket 38, a screw 39, a screw sleeve 40, a spring rod 41 and a ball 42. The bracket 38 is vertically fixed on the upper side of the base 1, the screw 39 is horizontally slidably sleeved in the bracket 38, the screw sleeve 40 is threadedly sleeved on the outer end of the screw 39, and is rotatably connected to the bracket 38, the spring rod 41 is vertically fixed on the end of the screw 39, and the ball 42 is rollingly embedded in the bottom end of the spring rod 41. A plurality of second inclined platforms 43 are fixedly installed on the upper side of the cover mold 2, and the plurality of second inclined platforms 43 are evenly distributed in a ring shape. After buckling, the upper surface of the cover mold 2 is located in the semicircular area at the bottom end of the ball 42. After the ball 42 contacts the cover mold 2, the spring rod 41 is compressed and shrinks upward, so that the cover mold 2 is pressurized and tightly buckled on the bottom mold 3.

[0046] When using this equipment for operation, the cover mold 2 is clamped on the upper side of the bottom mold 3, and the cover mold 2 and the bottom mold 3 are sealed and sleeved. After the cover mold 2 and the bottom mold 3 are installed, the screw sleeve 40 is screwed. Under the interference of the thread, the screw sleeve 40 drives the screw rod 39 to slide, driving the spring rod 41 to move to the upper side of the cover mold 2, and the ball 42 rolls in contact with the cover mold 2. At the same time, the spring rod 41 is compressed, and the cover mold 2 is tightly buckled on the upper side of the bottom mold 3.

[0047] After the cover mold 2 is buckled, a ladle is used to pour a preset volume of molten metal into the equipment. During the pouring, the motor 27 is started, and the motor 27 drives the second gear 30 located on the upper side to rotate through the third gear 31, thereby rotating the transmission shaft 29 and the second gear ring 26. The transmission shaft 29 drives the second gear 30 located on the bottom side to rotate, thereby causing the first gear ring 25 to rotate synchronously, thereby realizing the synchronous reverse rotation of the cover mold 2 and the bottom mold 3.

[0048] When pouring molten metal, the output end of the ladle is buckled on the rotating tube 9, pressing the rotating tube 9 downward, and the sliding tube 8 moves downward synchronously, driving the impeller 10, the sliding rod 14 and the retaining ring 17 to move downward, stretching the first tension spring 15, and the retaining ring 17 moves downward. The two push rods 22 are pulled close to each other through the two rocker rods 24, so that the two sealing blocks 23 are close to each other, blocking the top input end of the guide tube 13, and at the same time making the guide cavity 11 and the casting cavity conductive, the sliding rod 14 moves downward, driving the multiple connecting rods 18 to move downward, so that the rack 19 moves downward, and the rack 19 drives the first gear 20 to drive the rotating shaft 5 to rotate, and the rotating shaft 5 drives the push block 4 to deflect, so that the push block 4 protrudes out of the placement groove 6, which has the function of guiding upward.

[0049] When the bottom mold 3 rotates, it drives multiple push blocks 4 to deflect. Due to the guiding effect of the push blocks 4, the molten metal is pushed upward and squeezed by the cover mold 2, thereby causing the bubbles inside the molten metal to burst, allowing the gas to flow out and eventually remain in the air cavity 7, making the interior of the molten metal full and avoiding the presence of bubbles inside after solidification, thereby ensuring the casting quality.

[0050] The bottom mold 3 rotates, driving the slide pipe 8 to rotate, and the slide pipe 8 drives the impeller 10 to rotate, guiding the molten metal downward to enter the casting cavity.

[0051] After the molten metal pouring is completed, the motor 27 stops rotating, the ladle is separated from the upper side of the rotating tube 9, and the pouring is stopped.

[0052] After the pouring stops, the pressure on the slide tube 8 is released, the first tension spring 15 recovers, and the retaining ring 17 moves upward, so that the two push rods 22 move away from each other, and the two sealing blocks 23 move away from each other, thereby making the two sealing blocks 23 move away from each other, cutting off the diversion cavity 11 and the casting cavity, and at the same time making the top of the diversion tube 13 connected to the diversion cavity 11, and the excess molten metal flows from the drain pipe 12 into the external recovery equipment.

[0053] The first tension spring 15 is reset, the slide rod 14 moves upward, and drives the rack 19 to move upward, thereby causing the first gear 20 to reverse, and the first gear 20 drives the rotating shaft 5 to reverse, thereby causing the push block 4 to reverse and hide in the placement groove 6, so that the internal upper surface of the bottom mold 3 is flush, forming a complete casting cavity. At this time, the molten metal fills the entire casting cavity under the action of gravity, and the gas generated after the bubble bursts remains in the air cavity 7.

[0054] After a period of cooling and standing, the molten metal solidifies and solidifies to form a brake disc. Then, the screw sleeve 40 is rotated in the opposite direction, the spring rod 41 is separated from the upper side of the cover mold 2, the pressure is released, and the cover mold 2 is lifted by the handle 44. The cover mold 2 is separated from the bottom mold 3, and then the rotating tube 9 is pressed to deflect the push block 4, pushing the solidified brake disc upward and separating it from the bottom mold 3, achieving rapid demoulding and facilitating removal.

[0055] During the metal liquid pouring process, the motor 27 runs, causing the bottom mold 3 to drive multiple first inclined platforms 37 to rotate, and the cover mold 2 to drive multiple second inclined platforms 43 to rotate. After the first inclined platform 37 contacts the roller 36, the hammer 35 is pushed downward, pulling the second tension spring 34. After the first inclined platform 37 is separated from the roller 36, the second tension spring 34 is reset, driving the hammer 35 to deflect rapidly, hammering the bottom mold 3, and the second inclined platform 43 contacts the ball 42, lifting the spring rod 41. The spring rod 41 is compressed. After the ball 42 is separated from the second inclined platform 43, the spring rod 41 returns to its original length, causing the ball 42 to quickly collide with the cover mold 2, thereby shocking the cover mold 2.

[0056] When the cover mold 2 and the bottom mold 3 rotate, the first inclined platform 37 and the second inclined platform 43 rotate at the same time, so that the hammer 35 and the ball 42 intermittently hit the bottom mold 3 and the cover mold 2 respectively, causing them to vibrate, thereby vibrating the molten metal inside the casting cavity, further causing the bubbles to fully burst, facilitating the discharge of gas, and further ensuring the casting quality.

[0057] Under the disturbance of the multiple push blocks 4 and the vibration of the hammer 35 and the ball 42, the molten metal can more fully fill the casting cavity, thereby ensuring that the casting cavity is enriched and further ensuring the casting quality.

[0058] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
