Problems solved by technology

The main reason is that the two ends of the feeding surface of a split hole in the middle of the upper mold are the same size, and the split hole deviates from the groove of the lower mold cavity by a certain distance, so that the material in the groove of the lower mold cavity is sufficient. During the extrusion process, the profile will be deformed due to insufficient material supply in the groove or uneven speed when the aluminum material is extruded from the cavity; It is better to cause problems such as hand feeling or welding lines on the surface of the profile

Embodiment Construction

[0018] Referring to Fig. 1~2, the novel railing handrail aluminum profile hot extrusion mold that the present invention relates to is formed by superimposing upper die 1 and lower die 2 before and after, and assembling (tight fit) with two screws and two pins in the middle.

[0019] Referring to Figures 3 to 4, five splitter bridges 1.2 are arranged on the feed surface of the upper die 1, and five splitter holes 1.1 are formed between the five splitter bridges 1.2, among which the middle splitter hole shrinks gradually from large to small to form a large , small head, and the big end is placed in the center of the feed surface of the upper die 1, which is called the straight flushing groove splitter hole 1.1.1, and the center of the discharge face of the upper die 1 is provided with a core 1.3, the core The outer edge of 1.3 is provided with a mold core empty knife 1.4.

[0020] Referring to Figures 5-6, the feed surface of the lower die 2 is provided with a welding chamber 2....

Abstract

The invention relates to a novel aluminum profile hot extrusion mould for a hand rail, which is mainly used for the hot extrusion of building hand rail profile. The mould comprises an upper mold (1) and a lower mold (2) which are overlaid front and rear, the feeding surface of the upper mold (1) is provided with five flow-dividing bridges (1.2), five flow-dividing holes (1.1) are formed among the five flow-dividing bridges (1.2), the middle flow-dividing hole shrinks from large to small, thus forming a large head and a small head, furthermore, the large head is arranged in the center of the feeding surface of the upper mold (1), and the hole is called a direct impact groove flow-dividing hole (1.1.1). The feeding surface of the lower mold (2) is provided with a welding chamber (2.1), the rear of which is provided with a mold cavity (2.3), and the middle of the mold cavity (2.3) is provided with a groove position (2.3.1) which is arranged directly below the large head end of the direct impact groove flow-separating hole (1.1.1). The bottom of the welding chamber (2.1) is provided with an arc-shaped flow-blocking plate (2.3) in an upward convex way along the cavity wall of the mold cavity (2.2). The mould ensures adequate feeding at the groove part of the mold cavity of the lower cavity and the uniform discharging of the extruded aluminum profile, without the problems of hand feeling and welding strips, etc.

Description

(1) Technical field [0001] The invention relates to an aluminum profile hot extrusion die. It is mainly used for hot extrusion of building railing handrail profiles. It belongs to the technical field of mold processing. (2) Background technology [0002] Aluminum products have a series of excellent characteristics, such as good strength, good weather resistance, low density, easy extrusion and so on. Therefore, aluminum profiles are widely used in construction and industry. At present, the handrails of building railings are not only required to have good shape and beautiful appearance, but also to be durable. The shape of the railing is: a large semicircle with a groove in the middle with a width of 12.7mm and a depth of 20.5mm, as shown in Figure 7. At present, the production of such products often has poor surface quality, no shape, difficulty in ensuring the opening size, and inconsistency between the front and back of the profile. Thereby, the production time and pr...
