[0025] Based on the above structure, the extrusion rod pad 2 of the butterfly head assembly of extruder can slide along the up-down direction instead of horizontal direction, and correspondingly, the sliding slot also extends along the up-down direction. In this way, the degree of wear of the sliding slot is consistent when the extrusion rod pad 2 slides, and the situation that the bottom side sliding slot is severely worn while the top side sliding slot is slightly worn in the prior art does not occur. Therefore, the maintenance frequency of the equipment is much lower, and the components in the sliding slot do not need to be frequently replaced, thus reducing the maintenance cost. In addition, the butterfly head assembly of the utility model further comprises a hydraulic abutting structure 7 arranged on the connecting block 4. The hydraulic abutting structure 7 can quickly change the abutting force. When the extrusion rod pad 2 needs to slide, the hydraulic abutting structure 7 reduces or removes the abutting force, so that the extrusion rod pad 2 can slide in the sliding slot with low resistance. When the extrusion rod pad 2 slides to the extrusion station, in order to ensure the accurate position of the extrusion rod pad 2, the hydraulic abutting structure 7 increases the abutting force to tightly abut the extrusion rod pad 2, so that the displacement of the extrusion rod pad 2 is not easy to occur, thereby ensuring the normal production.
