Embodiment Construction
[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0029] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

The invention relates to an aluminum profile extrusion die and an extrusion forming method and manufacturing method thereof. The aluminum profile extrusion die comprises an upper die and a lower die,the lower die comprises a lower die base and a first hard mosaic block, an installing groove is formed in the lower die base, a plurality of installing holes are formed in the first hard mosaic block,the first hard mosaic block penetrates the installing holes through multiple first fastening pieces to be fixed into the installing groove, the first fastening pieces are in interference fit with theinstalling holes, and the magnitude of interference is 0.005 mm-0.012 mm; and the lower die is provided with a die hole penetrating the lower die base and the first hard mosaic block, a lower die working zone is formed in the position, corresponding to the die hole, of the first hard mosaic block, and the multiple first fastening pieces are distributed in a central symmetry manner with the central axis of the die hole as the center. According to the aluminum profile extrusion die, the abrasive resistance is obviously improved, the effective service life is obviously prolonged, and meanwhile,the surface quality of a proximate matter product is greatly improved. The manufacturing method of the aluminum profile extrusion die has the beneficial effects that the process is simple, the manufacturing period is short, and cost is low.
Description
technical field [0001] The invention relates to the field of moulds, in particular to an aluminum profile extrusion die, an extrusion molding method and a manufacturing method thereof. Background technique [0002] Hollow aluminum profiles generally adopt forward extrusion, the aluminum rod and the main cylinder of the extrusion machine move in the same direction, and the hollow aluminum profiles are extruded after splitting and welding of the splitting combination die. The shunt combination mold is divided into upper mold and lower mold, and the core head of the upper mold is generally made of 4Cr5MoSiV1 hot work mold steel. The working belt of the core head of the upper die is in contact with the hot aluminum rod, and the working belt of the core head bears a large frictional stress. The working belt of the core head is easy to wear, and the thickness and meter weight of the hollow aluminum profile will increase after the wear, and the increased thickness will lead to poor...
