The first electromagnet can adsorb the collar 551 and make the excess material push rod 550 movable relative to the collar 551, when the second electromagnet is powered on, the first electromagnet is powered off, so that the collar 551 can be adsorbed on the excess material push rod 550 and move together with the excess material push rod 550, and the extrusion die 210 with the excess material stripped is pushed onto the conveyor belt 110 from the clamping mechanism 520, so as to transfer the extrusion die 210 through the conveyor belt 110.

The extruder further includes a die transfer apparatus 700, the extrusion die 210 from which the excess material is removed is conveyed toward the die housing 200 by the conveyor 110 and the extrusion die 210 is nipped by the die transfer apparatus 700 onto a die storage table 710 to be assembled,

the mold storage table 710 is disposed at a side of the clamping device 410, and when the extrusion mold 210 is pushed onto the mold base 200, the mold transfer apparatus 700 clamps the extrusion mold 210 on the mold storage table 710 onto the clamping device 410, and after the extrusion mold 210 with the excess removed is pushed onto the clamping device 410 by the columnar pushing head 402, the mold transfer apparatus 700 clamps the extrusion mold 210 onto the mold storage table 710. When the extrusion die 210 with the excess material on the die base 200 is disassembled, a new extrusion die 210 needs to be installed on the die base 200 to perform extrusion molding of the next round, the hook-shaped push head 403 can push the extrusion die 210 towards the direction of the conveyor belt 110, and in the process of replacing the die, the new extrusion die 210 is clamped onto the clamping device 410 by the die transfer device 700, and kept stable and not to topple under the action of the clamping device 410, and the extrusion die 210 is pushed onto the die base 200 to complete assembly under the pushing of the hook-shaped push head 403.

The mold transferring apparatus 700 includes a transferring base 720 and a jaw assembly 730 translatable in a length direction of a driving belt, and the jaw assembly 730 includes a clamping lifter 740 liftable with respect to the transferring base 720 and a jaw 750 disposed at an end of the clamping lifter 740. The jaw assembly 730 is movable along the length of the belt to move between the clamping device 410 and the die magazine to transfer the extrusion die 210, and the clamping lifter 740 can adjust the height position of the jaws 750 to lift and transfer the extrusion die 210 after the jaws 750 clamp the extrusion die 210.

While the utility model has been described in terms of embodiments, it will be appreciated by those skilled in the art that the utility model is not limited thereto but rather includes the drawings and the description of the embodiments above. Any modifications which do not depart from the functional and structural principles of the present utility model are intended to be included within the scope of the appended claims.
