A double-drive riding wheel horizontal centrifugal casting machine. The casting machine comprises a base fixed on the ground, and two supporting seats are arranged on one side, deviating from the ground, of the base along the length direction. A pair of riding wheels for supporting the casting mould are arranged on the two supporting seats, and the riding wheels are symmetrically arranged along the central line of the width direction of the positioning seat. Meanwhile, a driving motor is arranged on the base and connected with one of the supporting wheels through a chain, a rotating shaft penetrates through the supporting wheel, chain wheels are sleeved on the rotating shaft and the output shaft of the driving motor, and the chain is sleeved on the two chain wheels simultaneously. In the process of casting a casting, an operator places the casting mold between the two riding wheels of the same pair through a hoisting device, and the outer side wall of the casting mold is tangent to the four riding wheels simultaneously. At the moment, an operator starts the driving motor to drive the riding wheel to rotate through the chain so as to realize the purpose of driving the casting mould to rotate, and the operator can cast liquid metal conveniently. The base is equipped with the positioning seat between two supporting seats, is equipped with buffer gear on the positioning seat, and buffer gear deviates from the backing roll of base one side including setting up at the positioning seat, and the backing roll sets up along the length direction of positioning seat, and the axis of backing roll is parallel with the axis of casting mould. The backing roll all rotates along length direction's both ends and is connected with a bracing piece, and gag lever post of fixedly connected with is simultaneously on two bracing pieces, and the gag lever post setting is kept away from the one end of backing roll at the bracing piece. And the axis symmetry of backing roll along the casting mould is equipped with two, and the positioning seat is seted up two waist shape holes that run through the positioning seat along length direction's one end, and one side that the base was kept away from in two waist shape holes all inclines to the one side that faces earlier and is the splayed. One of the limiting rods penetrates through one of the waist-shaped holes, the other limiting rod penetrates through the other waist-shaped hole, and the limiting rods are arranged in the waist-shaped holes in a sliding mode. A locating lever is simultaneously penetrated and arranged on two supporting rods at the same end of the locating seat, and the two supporting rods are both connected with the locating lever in a sliding manner. Two sliding parts are arranged at two ends of the base along the length direction of the positioning rod, and one ends, far away from the base, of the sliding parts are fixed on the positioning rod. And the locating lever is equipped with first spring in the cover between bracing piece and slider, and the one end of first spring is fixed in on the bracing piece, and the other end is fixed in on the slider, and first spring is in partial compression state for a long time. And in the process of dropping the casting mold, an operator simultaneously pushes the casting mold against the two supporting rollers, so that the casting mold applies pressure to the two supporting rollers under the action of gravity. The backing roll promotes the gag lever post through the bracing piece and slides along waist shape hole length direction this moment to the gag lever post overlaps between two bracing pieces and is equipped with the live-rollers, has the clearance between live-rollers and the waist shape hole, with the gliding fluency of promotion gag lever post in waist shape hole. Meanwhile, the waist-shaped hole limits the moving direction of the limiting rod, so that the supporting rod drives the positioning rod to be close to the base, and the positioning rod is limited through the sliding piece. The supporting rod is enabled to gradually approach the sliding piece, the supporting rod compresses the first spring, and the first spring has elastic restoring force after being compressed. And under the effect of elastic restoring force, the first spring buffers the energy absorption to the bracing piece to reach the effect of buffering the casting mould. The support rollers can support the mould during rotation of the mould, so that the stability of the mould during rotation is improved. Meanwhile, the outer side wall of the supporting roller is sleeved with a rubber pad, the rubber pad is made of rubber, the rubber pad is soft and elastic, so that the rubber pad can buffer and absorb energy for the rotary casting mold, the casting mold is damped, and the stability of the casting mold during rotation is improved. The sliding part comprises a guide cylinder fixedly connected to the base, a guide rod is arranged in the guide cylinder in a sliding mode, the inner walls of the guide cylinder on the side wall of the guide rod are attached to each other, and the guide rod is fixed to the positioning rod. The guide cylinder is provided with air holes on the side wall close to the base, and when the guide rod slides along the guide cylinder, the guide rod compresses air in the guide cylinder. At the moment, the air is slowly discharged through the air holes, so that the sliding degree of the guide rod is slowed down, and the casting mold is further buffered. Meanwhile, a sealing ring is embedded in one end, away from the positioning rod, of the positioning rod along the peripheral direction, the sealing ring is made of rubber, and the rubber is softer and has elasticity, so that the sealing ring seals a gap between the guide rod and the guide cylinder, the gas discharge speed is further reduced, and the buffering performance of the sliding part is guaranteed. Two bracing pieces on same locating lever all are equipped with a joint spare in relative one side, and the joint spare includes locating plate, pull rod, fixture block and second spring, and on the locating plate was fixed in the bracing piece, the pull rod was worn to locate on the locating plate, and the pull rod slides and sets up on the locating plate. The fixture block is fixedly connected to one end, close to the positioning rod, of the pull rod, and an inclined plane is arranged on one side, close to the supporting rod and far away from the pull rod, of the fixture block. One side of the positioning plate close to the clamping block is provided with a plurality of clamping grooves matched with the clamping block along the length direction, and the clamping block is inserted in the clamping grooves. The second spring is sleeved on the pull rod between the positioning plate and the clamping block, one end of the second spring is fixed on the positioning plate, and the other end of the second spring is fixed on the clamping block. When the supporting rod approaches the guide rod, the supporting rod drives the pull rod to move along the length direction of the positioning plate through the positioning plate. The edge and the inclined plane of draw-in groove are inconsistent this moment to produce the inclined thrust to the fixture block, make the fixture block break away from and compress the second spring in following the draw-in groove, the second spring has elastic restoring force by the compression. And in the moving process of the supporting rod, the second spring pushes the clamping block to be inserted into the other clamping groove and the clamping blocks are sequentially circulated. The draw-in groove is spacing to the fixture block simultaneously to reach the effect of spacing bracing piece, thereby reduce first spring and appear kick-backing, lead to the bracing piece to take place the ejecting condition of casting mould from the casting machine. The implementation principle of the embodiment of the application is as follows: an operator lifts the casting mould by the lifting device and places the casting mould between the two supporting rolls. The operator drops the mould so that the support roll abuts against the mould. Under the action of self gravity, the casting mold applies pressure to the two supporting rollers, so that the supporting rollers push the limiting rod to slide along the length direction of the waist-shaped hole through the supporting rod. At the moment, the supporting rod compresses the first spring, so that the first spring buffers and absorbs energy to the supporting rod, and the effect of buffering the casting mold is achieved.
