Porous extrusion mold for aluminum profile

Abstract

The invention relates to a porous extrusion mold for an aluminum profile. The porous extrusion mold comprises a flow guide mold; the upper surface of the flow guide mold is provided with first feedingopenings; the lower surface of the flow guide mold is provided with second feeding openings; the first feeding openings and the second feeding openings penetrate through the flow guide mold; center shafts of the first feeding openings and the second feeding openings are overlapped with each other; the inner diameter of each first feeding opening is smaller than that of each second feeding opening; a main body of the flow guide mold and a main body of the extrusion mold are correspondingly internally provided with four bolt holes which are in central symmetry with respect to the center shaftsof the flow guide mold and the extrusion mold; a plurality of first feeding openings and second feeding openings are formed; and at least two groups of first feeding openings and second feeding openings are formed. The porous extrusion mold for the aluminum profile can conveniently change an extrusion type feeding mode into an independent feeding mode of the aluminum profile by virtue of the firstfeeding openings and the second feeding openings which are each of a horn-shaped structure, greatly reduces horizontal flowing of the aluminum profile in an extrusion process and effectively guarantees that the discharging speed of the aluminum profile is kept the same in the extrusion process.

Description

technical field [0001] The invention relates to the technical field of extrusion dies for aluminum profiles, in particular to a porous extrusion die for aluminum profiles. Background technique [0002] Many car body structure frames are made of industrial aluminum profiles, whether it is more or less body structures such as cars and trucks, all use industrial aluminum profiles. Because industrial aluminum profiles are used in the automotive industry, in terms of manufacturing process, as alloy materials, the metal elements added to aluminum alloys are all used in cutting-edge industries, whether it is strength, stiffness, wear resistance, etc. There are relatively high requirements. [0003] In the existing aluminum profile extrusion die, because the feeding mode is in the state of simultaneous feeding, lateral flow will occur during the extrusion process of the aluminum profile, so that the extrusion speed of the aluminum profile during the extrusion process is inconsisten...
