Lifting structure for extrusion tool
The invention provides a lifting structure for an extrusion tool. The lifting structure comprises the extrusion tool and a lifting block, wherein an arc slot and a square slot are formed in the upper surface of the extrusion tool; the depth of the arc slot at an intersection with the square slot is larger than that of the square slot; the lifting block is arranged in the square slot and is fixedly connected to the extrusion tool. The lifting structure for the extrusion tool, which is provided by the invention, has the advantages and the beneficial effects the lifting block is convenient to mount; an extruder is not required to be dismounted in a product extrusion process, so that the trouble that a worker mounts and dismounts a lifting ring screw at a position close to the high-temperature extrusion tool is avoided; compared with the conventional screw tightening method, the steel wire rope threading method is more convenient. 1. An extrusion tool lifting structure, characterized in that comprises an extrusion tool (1) and a lifting block (2), the extrusion tool (1) has on the upper surface of arc groove (11) and tube (12), said groove (11) in the square groove (12) is greater than the depth of the junction of the square groove (12) of the depth, the lifting block (2) is arranged in the square groove (12) in, and fixing the connected to the extruding tool (1). 2. The extruding tool lifting structure according to Claim 1, characterized in that the stated arc chute (11) and the square grooves (12) perpendicular to the extending direction. 3. The extruding tool lifting structure according to Claim 1, characterized in that the said square slot (12) located in the groove (11) of the bottom surface of the two sides is provided with a 1st threaded hole (13), and the states the hoisting up block (2) includes two 2nd threaded hole (21) and the screw (22), the two 2nd threaded hole (21) corresponding to the two 1st threaded hole (13), and the screw (22) to extend into the threaded holes 1st (13) and the 2nd screw thread hole (21) in order to fixing the extrusion tool (1) and the lifting block (2). 4. The extruding tool lifting structure according to Claim 3, characterized in that the lifting block (2) includes two ends of the connecting part (23) and in the middle of the lifting part (24), the two 2nd threaded holes (21) arranged in the two connecting parts (23), in the lifting block (2) is mounted in the square groove (12) after the, said lifting part (24) corresponding to the arc the position of the (11). 5. The extruding tool lifting structure according to Claim 4, characterized in that the lifting part (24) of the lower surface is a cambered surface. 6. The extruding tool lifting structure according to Claim 4, characterized in that the lifting part (24) is cylindrical. 7. An extrusion tool lifting method, characterized in that comprises: Steps (A): in the extrusion tool (1) is provided on the upper surface of arc groove (11) and tube (12), said groove (11) in the square groove (12) is greater than the depth of the junction of the square groove (12) the depth; Steps (B): the lifting block (2) is arranged in the square groove (12) in, and fixing the connected to the extruding tool (1); Steps (C): the steel wire extends into the said groove (11) and from the lower passes through the lifting block (2); Steps (D): the hoisting up states upwards through the extrusion tool (1) and the lifting block (2). 8. The extruding tool lifting method according to Claim 7, characterized in that the stated arc chute (11) and the square grooves (12) perpendicular to the extending direction. 9. The extruding tool lifting method according to Claim 7, characterized in that the lifting block (2) includes two ends of the connecting part (23) and in the middle of the cylindrical lifting part (24).
