The gas inside the die-casting tank 18 is discharged along the air hole 15 under the action of pressure, so as to realize continuous and efficient die-casting of the workpiece, and at the same time, defects such as air holes 15 in the workpiece can be avoided.

[0031] When the movable mold 11 moves downward, it drives the connecting rod 29 and the vertical rod 30 to move downward, so that the latch tooth 36 moves downward, and drives the gear 31 meshing with the latch tooth 36 to start rotating, thereby driving the horizontal shaft 19 to start rotating. When the vertical rod 30 moves downward, it drives the horizontal rod 33 to move downward until the other end of the horizontal rod 33 squeezes the spray trigger at the top of the sprayer 34, so that the sprayer 34 is started, and the demoulding liquid is sprayed along the nozzle 35 at the bottom of the sprayer 34. When the horizontal shaft 19 rotates, it drives the sprayer 34 threadedly connected to the threaded portion 20 to the right along the second guide rod 37, so that the nozzle 35 moves accordingly. When the sprayer 34 moves to the rightmost end of the threaded portion 20, the spray closing switch on its right side wall contacts the block 21 and is squeezed, so that the sprayer 34 is closed. Through the above steps, it can be moved to the right before die casting. A layer of demoulding liquid is evenly sprayed on the inside of the die-casting tank 18 to prevent the surface of the workpiece from being damaged during demoulding. The sprayer 34 drives the friction rod 38 to move rightward during the movement. When the friction rod 38 moves to the right, it drives the friction block 39 to move to the right, so that the baffle connected to the friction block 39 moves accordingly, and the bottom hole 23 is sealed, thereby ensuring the sealing of the die-casting tank 18. When the die-casting is completed, the vertical shaft 9 moves upward, so that the movable mold 11 moves upward, and drives the vertical rod 30 to move upward accordingly, so that the gear 31 rotates in the opposite direction, driving the sprayer 34 and the baffle to reset. When the vertical rod 30 moves upward, it drives the slider 25 at the bottom to move upward along the third guide rod 24, so that the top rod 26 at the top of the slider 25 moves upward along the bottom hole 23, thereby lifting the workpiece in the die-casting tank 18, which is convenient for collecting the workpiece.

[0032] When the movable mold 11 moves downward, it drives the feeding trigger 49 to move downward. When the movable mold 11 moves downward until it is completely closed with the fixed mold 17, the feeding trigger 49 at the bottom of the movable mold 11 is squeezed by the fixed mold 17, so that the air pump is started, and the material flows into the vertical cylinder 40 and the connecting cylinder 43 along the feeding pipe 41. The one-way valve 42 can prevent the material from flowing back. When feeding, the gas enters the cylinder 46 along the right air inlet, pushing the second piston to move leftward, so that the piston rod 45 moves leftward, driving the first piston to move toward the left end of the conveying cylinder 44, generating pressure on the material in the connecting cylinder 43, so that The material flows out along the feed pipe 14 at the bottom of the vertical cylinder 40. After one loading is completed, the air pump pumps gas into the left air inlet, causing the second piston to move in the opposite direction, driving the piston rod 45 and the first piston to move in the opposite direction, so that negative pressure is generated inside the vertical cylinder 40. Under the action of negative pressure, the material flows into the vertical cylinder 40 again, thereby realizing continuous loading. When the piston rod 45 moves, it drives the movable block 47 to move between the blocks 48. The blocks 48 can make the movement distance of the piston rod 45 consistent, so that the output of the material remains stable. The output of the material can be controlled by adjusting the spacing between the blocks 48.

Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
