[0022] The impact mechanism includes a support frame 32, a support rod 33, a second tension spring 34, a hammer 35 and a roller 36.

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

[0023] The limiting mechanism includes a clamping frame 38, a screw rod 39, a nut sleeve 40, a spring rod 41 and a ball 42. The clamping frame 38 is vertically and fixedly installed on the upper side of the base 1. The screw rod 39 is horizontally slidably sleeved in the clamping frame 38. The nut sleeve 40 is threadedly sleeved on the outer end of the screw rod 39 and is rotatably connected to the clamping frame 38. The spring rod 41 is vertically and fixedly installed at the end of the screw rod 39. The ball 42 is rotatably embedded at 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 die 2, and the plurality of second inclined platforms 43 are evenly distributed in a ring shape. After being buckled, the upper surface of the cover die 2 is located within the semi-circular area at the bottom end of the ball 42. After the ball 42 contacts the cover die 2, the spring rod 41 is compressed and contracts upward, so that the cover die 2 is pressed and tightly buckled on the bottom die 3.

[0024] When using this device for operation, the cover die 2 is clamped on the upper side of the bottom die 3, and the cover die 2 and the bottom die 3 are hermetically sleeved. After the cover die 2 and the bottom die 3 are installed, the nut sleeve 40 is rotated. Under the interference of the thread, the nut sleeve 40 drives the screw rod 39 to slide, driving the spring rod 41 to move to the upper side of the cover die 2. The ball 42 is in rolling contact with the cover die 2. At the same time, the spring rod 41 is compressed, and the cover die 2 is tightly buckled on the upper side of the bottom die 3.

[0025] After the cover die 2 is buckled, a ladle is used to pour a preset volume of molten metal into the device. During pouring, the motor 27 is started. The motor 27 drives the second gear 30 located on the upper side to rotate through the third gear 31, so that the transmission shaft 29 and the second gear ring 26 rotate. The transmission shaft 29 drives the second gear 30 located on the lower side to rotate, so that the first gear ring 25 rotates synchronously, and then the cover die 2 and the bottom die 3 rotate synchronously and in opposite directions.

[0026] During the pouring of molten metal, the output end of the ladle is buckled on the rotating pipe 9, and the rotating pipe 9 is pressed down. The sliding pipe 8 moves down synchronously, driving the impeller 10, the sliding rod 14 and the clamping ring 17 to move down, stretching the first tension spring 15. The clamping ring 17 moves down, pulling the two push rods 22 to approach each other through the two swing rods 24, so that the two sealing blocks 23 approach each other, blocking the top input end of the diversion pipe 13, and at the same time making the diversion cavity 11 communicate with the casting cavity. The sliding rod 14 moves down, driving the plurality of connecting rods 18 to move down, so that the rack 19 moves down. The rack 19 drives the first gear 20 to drive the rotating shaft 5 to rotate. The rotating shaft 5 drives the push block 4 to deflect, so that the push block 4 protrudes from the placement groove 6, having an upward diversion function.

[0027] 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 extruded by the cover mold 2. As a result, the bubbles inside the molten metal burst, allowing the gas to flow out and finally remain in the air cavity 7, making the inside of the molten metal full and avoiding the existence of bubbles after solidification, thus ensuring the casting quality.

[0028] The bottom mold 3 rotates, driving the sliding pipe 8 to rotate. The sliding pipe 8 drives the impeller 10 to rotate, guiding the molten metal downward and making it enter the casting cavity.

[0029] After the molten metal is poured, the motor 27 stops rotating, the ladle is disengaged from the upper side of the rotating pipe 9, and the pouring stops.

[0030] After the pouring stops, the pressure on the sliding pipe 8 is released, the first tension spring 15 resumes its original state, driving the snap ring 17 to move upward, causing the two push rods 22 to move away from each other, driving the two sealing blocks 23 to move away from each other. As a result, the two sealing blocks 23 move away from each other, cutting off the guiding cavity 11 from the casting cavity. At the same time, the top of the guiding pipe 13 is in communication with the guiding cavity 11, and the excess molten metal flows into the external recycling equipment through the discharge pipe 12.

[0031] The first tension spring 15 resets, the sliding rod 14 moves upward, driving the rack 19 to move upward. As a result, the first gear 20 rotates in reverse, the first gear 20 drives the rotating shaft 5 to rotate in reverse, and thus the push block 4 rotates in reverse and hides in the placement groove 6, making the upper surface of the inside of the bottom mold 3 flat, forming a complete casting cavity. At this time, under the action of gravity, the molten metal fills the entire casting cavity, and the gas generated after the bubbles burst remains in the air cavity 7.

[0032] After a period of cooling and standing, the molten metal solidifies to form a brake disc. Then, the screw sleeve 40 is rotated in the reverse direction, the spring rod 41 is disengaged from the upper side of the cover mold 2, the pressure is released, the cover mold 2 is lifted by the handle 44, the cover mold 2 is disengaged from the bottom mold 3, and then the rotating pipe 9 is pressed, so that the push block 4 deflects, pushing the solidified brake disc upward and disengaging it from the bottom mold 3, realizing rapid demolding and facilitating taking out.

[0033] During the pouring of the molten metal, the motor 27 operates, 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, it pushes the hammer 35 downward, pulling the second tension spring 34. After the first inclined platform 37 is disengaged from the roller 36, the second tension spring 34 resets, driving the hammer 35 to deflect rapidly and hammer the bottom mold 3. The second inclined platform 43 contacts the ball 42, lifting the spring rod 41, and the spring rod 41 is compressed. After the ball 42 is disengaged 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, exerting a shock effect on the cover mold 2.

[0034] When the cover die 2 and the bottom die 3 rotate, the first inclined platform 37 and the second inclined platform 43 rotate simultaneously, causing the hammer 35 and the ball 42 to intermittently strike the bottom die 3 and the cover die 2 respectively, making them vibrate, so that the molten metal inside the casting cavity is vibrated, further causing the bubbles to fully burst, facilitating the discharge of gas, and thus further ensuring the casting quality.

[0035] Under the disturbance of 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, thus ensuring that the casting cavity is filled and further ensuring the casting quality.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
