The surface of the pulley 83 is fixed with a latch 84, which meshes with the gear 82. The inner wall of the base 1 is rotatably connected to a pulley 85. The inner wall of the base 1 is rotatably connected to a reciprocating screw rod 86. The reciprocating screw rod 86 passes through a slider 87.

When the motor 81 rotates forward, the movable plate 2 950 drives the fixed plate 2 953 to rotate, and then drives the reciprocating The screw rod 2 91 rotates synchronously, and at this time, the movable plate 96 can reciprocate on the surface of the base 1, driving the clamping rod 92 to move synchronously. When the clamping rod 92 passes through the clamping holes of the clamping plate 1 93 and the clamping plate 2 94, the motor 81 is turned off, and the clamping rod 92 limits the clamping plate 1 93 and the clamping plate 2 94 to complete the mold locking, which can prevent the upper mold 6 and the lower mold 7 from being expanded and affecting the molding during processing. When the mold needs to be taken out, the motor 81 is continued to be turned on to rotate forward, and the reciprocating screw rod 2 91 drives the movable plate 96 to reset, and the clamping rod 92 is now separated from the clamping plate.

When the surface of the movable plate 890 contacts the surface of the fixed plate 893, the movable plate 890 rotates and contacts the surface of the fixed plate 893 through the limit plate 892, driving the reciprocating screw rod 86 to rotate, thereby driving the slider 87 to move inward synchronously, and driving the ejector column 800 and the connecting plate 801 to rise through the linkage plate 88, thereby ejecting the formed mold. The motor 81 is continuously turned on and reversed, and the slider 87 is turned on and reversed. Blocks 87 move away from each other synchronously, and drive the top column 800 and the connecting plate 801 to move down and reset through the linkage plate 88. When the motor 81 rotates forward, the pulley 85 drives the movable plate 890 to rotate, and the surface of the movable plate 890 conflicts with the surface of the fixed plate 893, and the movable plate 890 flips over. The movable plate 890 does not conflict with the surface of the fixed plate 893, and the torsion spring 891 drives the movable plate 890 to reset.
