Abstract

The invention discloses a forming mold for a rectangular aluminum alloy provided with a convex part. The forming mold comprises an upper mold body and a lower mold body. The upper mold body is provided with common distribution holes, a decelerating distribution hole and a mold core. The lower mold body is provided with a mold cavity which is matched with the to-be-formed aluminum alloy provided with the convex part. The mold cavity comprises a rectangular forming part and a convex forming part. The decelerating distribution hole comprises a feeding port located above the convex forming part, adischarging port connected with the convex forming part, and a passage connected with the feeding port and the discharging port, wherein the passage gradually inclines outwards in the radial direction from the feeding port to the discharging port. According to the forming mold for the rectangular aluminum alloy provided with the convex part, the common distribution holes are used for feeding forthe common wall-thickness portions of the rectangular aluminum alloy in the mold cavity, and the decelerating distribution hole is used for feeding for the portion, provided with the convex part, of the rectangular aluminum alloy in the mold cavity so that the flow rate of melt can be controlled under the same extrusion system, it is ensured that the discharging speed of the common wall-thicknessportions and the discharging speed of the portion provided with the convex part are consistent, the internal stress is reduced, and the precision of finished products is improved.

Description

technical field [0001] The invention relates to a mold, in particular to a rectangular aluminum alloy forming mold with a protruding part. Background technique [0002] In modern material processing, aluminum alloy extrusion molding technology has been widely used. It uses an extruder to press aluminum rods heated to a certain temperature into a mold to form different shapes. The biggest difficulty in extrusion molding is to ensure that the extrusion speed of each part of the aluminum material is basically the same. Under these conditions, the uniform internal stress can be ensured and the size and shape of the profile can be stabilized only after the aluminum material is extruded. Existing molds generally control the extrusion speed of the profile through the length of the working belt, but this method has a strict scope of application and a narrow adjustment range. Especially for aluminum with asymmetric structure or uneven wall thickness, the adjustment ability is limi...
