[0032] A specific application of this embodiment is as follows: When it is necessary to replace and repair the lower mold 22, the electric telescopic rod 24 is driven to drive the positioning block 25 to move. When the positioning block 25 moves, it returns to the inside of the chute 23 away from the positioning groove 26, thereby rendering the first-layer installation component ineffective. Then, the pull rod 214 is pulled. The pull rod 214 drives the moving plate 213 to move. The second spring 215 facilitates the reset of the pull rod 214 when the lower mold 22 is reinstalled. When the moving plate 213 moves, it drives the sliding plate 211 to move on the fixed rod 210 through the connecting plate 212. When the sliding plate 211 moves, it drives the positioning rod 28 to move, thereby causing the positioning rod 28 to disengage from the positioning groove 26 and the positioning block 25. The first spring 29 exerts an elastic force on the positioning rod 28 to prevent the positioning rod 28 from disengaging from the positioning groove 26 and the positioning block 25 without human intervention. When the positioning rod 28 disengages from the positioning block 25 and the positioning groove 26, the lower mold 22 can be disengaged from between the positioning shells 21, and then replaced and repaired.

[0033] The motor 37 is started. The motor 37 drives the threaded rod 38 to rotate. When the threaded rod 38 rotates, it drives the upper mold 39 to move on the limiting rods 310, thereby approaching the lower mold 22, and then forming work is carried out. After forming, the upper mold 39 moves away from the lower mold 22. The sliders 32 move in the electric slide rails 31. When the sliders 32 move, they drive the support plate 33 to move. After the support plate 33 moves, the hydraulic cylinder 34 is started. The hydraulic cylinder 34 drives the top plate 35 to move, and then drives the ejector rods 36 through the top plate 35 to eject the formed material for collection.
