Automobile damping fixing piece sectional material die

Abstract

The invention discloses an automobile damping fixing piece sectional material die. The automobile damping fixing piece sectional material die comprises an upper die body and a lower die body which aremutually stacked. The feeding face of the upper die body is provided with eight peripheral flow dividing holes and eight flow dividing bridges. The peripheral flow dividing holes and the flow dividing bridges are evenly arranged in the circumferential direction, and a middle flow dividing hole is formed in the center. A large inner die core and a small inner die core are arranged on the discharging face of the upper die body, outer die cores are arranged on the two sides of the inner die cores, and a die core bridge is arranged between the two inner die cores. The lower die body is internallyprovided with a first-level welding-on chamber, a second-level welding-on chamber, a cavity and a product outlet in sequence, and the second-level welding-on chamber and a sectional material are consistent in outline. According to the automobile damping fixing piece sectional material die, it is guaranteed that the surface of the sectional material is smooth, the density and mechanical performance are perfect, the size is accurate, and using is excellent and perfect. The cost is reduced, and the machine feeding circulation time of the die is shortened; and the production efficiency of the sectional material is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a hot extrusion die, in particular to an automobile shock absorbing fixture profile die, which belongs to the technical field of aluminum alloy high-precision industrial material dies. Background technique [0002] Because aluminum has good extrusion formability, fast heat dissipation, light weight, good rigidity, certain corrosion resistance and dimensional stability, impact resistance, wear resistance, good attenuation performance, easy recycling, high thermal conductivity and electrical conductivity High performance, non-magnetic, good shielding and non-toxic. Therefore, aluminum alloy profiles are widely used in technical fields such as automobiles, LED lighting, ships, and aerospace. But in the automotive shock absorber profile (attached figure 1 ), there are the following technical difficulties. One: Because the extrusion ratio of the automotive shock absorbing fixture is small, the surface of the extruded profile is v...

AI Technical Summary

Problems solved by technology

One: Because the extrusion ratio of the profile of the automobile shock absorbing fixture is small, the surface of the extruded profile is very rough, and due to the high size requirements of the special-shaped multi-cavity shape, the filling of the middle rib is insufficient and the welding is poor, which directly causes this product to be unqualified

Second: the mold design structure is complex, the processing is difficult and takes a long time; profile products are difficult to form, the wall thickness of the cavity body is prone to deflection, dimensional deviation occurs, and the yield rate is low.
