Embodiment approach
[0028] As an embodiment of the present invention, the cross-section of the splitter rod 32 and the splitter ring 31 in the No. 1 splitter mold 3 is triangular, and the tip of the triangle faces the left fixed ring 2; the triangular tip surface of the splitter ring 31 and the splitter rod 32 The diamond 34 is fixedly connected; when working, the aluminum ingot enters the No. 1 splitter mold 3 under the action of extrusion force, and the triangular tip of the splitter rod 32 and the splitter ring 31 with the diamond 34 fixedly connected with the aluminum ingot first contacts the aluminum ingot, and the aluminum ingot Cutting; Diverting rod 32 and Diverting ring 31 use a triangular slope design to avoid the pressure that Diverting rod 32 and Diverting ring 31 bear when cutting the aluminum ingot, so that the force is more balanced, reducing the number of Diverting rods 32 and Diverting ring 31 The occurrence of cracks and fractures significantly improves the service life of the mo...

The invention belongs to the technical field of aluminum profile manufacturing and processing, and particularly relates to an extrusion forming die for an aluminum profile. The extrusion forming die comprises an outer die, fixing rings, a divergent die I, a divergent die II and an inner die, wherein the outer die is of a cylindrical structure, and the fixing rings are arranged on the two ends of the outer die; fixed blocks are symmetrically arranged on the outer surface of the side wall of the outer die, a cavity is arranged in one end, close to the side wall of the outer die, of each fixed block, and a gear I is arranged in the cavity; push rods are arranged above and below the gear I; a flow dividing ring is arranged at the center of the center of the divergent die I; uniformly distributed flow dividing rods are fixedly connected to the outer surface of the flow dividing ring; uniformly distributed flow dividing holes are arranged in the divergent die II, and the flow dividing holesare of a funnel-shaped design; and an air inlet is arranged in the side wall of the outer die. According to the extrusion forming die, the extrusion force is reduced, the machine loss is reduced, anda situation that the formed aluminum profile is broken, deformed and the like due to direct extrusion is avoided.
