Description

Technical Field

[0001] This utility model relates to the field of material extrusion die technology, specifically an extrusion die for an automotive anti-collision beam profile. Background Technology

[0002] The aluminum profile extrusion dies used in current automotive crash beam reinforcement frames are subject to high-temperature impacts during the extrusion molding process, which can easily lead to deformation of the extrusion die and thus affect the quality of the aluminum profile forming.

[0003] The existing publication number CN217289844U discloses an aluminum profile extrusion die for an automotive anti-collision beam reinforcement frame, including a die base, a discharge surface, and a discharge port. The discharge surface is provided on the outside of the die base, and the discharge port is opened inside the discharge surface for extruding aluminum rods. Cooling water tanks and cooling air tanks are sequentially opened inside the die base. This utility model designs cooling water tanks and cooling air tanks sequentially from the inside to the outside of the die base. A heat-conducting plate arranged in a ring array is connected between the cooling water tanks and cooling air tanks. One end of the heat-conducting plate protrudes from the die base. The cooling water tanks circulate water to cool the die base, and the cooling air tanks introduce air. The air is discharged through the air vents and holes of the heat-conducting plate to carry away heat. At the same time, the heat-conducting plate conducts heat outward from the die base. Thus, the multi-stage heat dissipation design in the overall structure improves the impact of high temperature on the extrusion die and reduces the quality problems of extruded workpieces caused by high temperature deformation of the extrusion die.

[0004] Existing technologies can reduce the quality problems of extruded workpieces caused by high-temperature deformation of extrusion dies to a certain extent. However, the material feeding of existing profile extrusion dies is uneven and not smooth, which affects the quality of product extrusion molding. Therefore, we propose an extrusion die for automotive anti-collision beam profiles. Utility Model Content

[0005] The purpose of this utility model is to provide an extrusion mold for automotive anti-collision beam profiles to solve the problem of uneven and unsmooth material feeding in the prior art, which affects the quality of product extrusion molding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extrusion die for automotive anti-collision beam profiles, comprising an upper die and a lower die, the upper die and the lower die cooperating with each other, the upper die comprising an upper die body, the upper die body having a feed hole, the upper die body having a central flow divider at the feed hole, the two sides of the central flow divider being connected to the upper die body via flow divider bridges respectively, the central flow divider and the two flow divider bridges dividing the feed hole into multiple flow dividers, the flow divider bridges having an arc-shaped structure, and the central flow divider having an upper die core at one end of the lower die.

[0007] Preferably, the upper mold core has flow channels at equal intervals, and the outer side of the upper mold core is provided with protrusions.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
