Aluminium profile extrusion device

Abstract

The invention provides an aluminium profile extrusion device which comprises an extrusion rod and an aluminium profile extrusion chamber matched with the extrusion rod, wherein the aluminium profile extrusion chamber is defined by a first mould base, a second mould base, a first material liner and a second material liner together; a discharge hole for molding a product is formed between the first mould base and the second mould base; mold inserts are fixed in the first mould base and the second mould base; first matching parts are arranged on the first material liner and the second material liner; second matching parts are arranged on the first mould base and the second mould base; the first matching parts and the second matching parts are respectively formed on contact surfaces between the material liners and the mould bases. The mould bases and the material liners are respectively provided with concave parts and convex parts which are matched with each other, so that the relative location between the mould bases and the material liners can be realized, the mould bases and the material liners are prevented from being staggered from each other along the vertical direction, and furthermore, the extrusion effect of aluminium profiles and the long-term operation of the extrusion device are guaranteed.

Description

technical field [0001] The invention relates to the field of alloy manufacturing, in particular to an aluminum extrusion device. Background technique [0002] The aluminum profile extrusion machine is the most critical equipment in the aluminum profile production industry. The aluminum ingot is extruded through the joint action of the main oil cylinder and the partial oil cylinder. The extrusion machine has a simple structure, high production efficiency and low cost, and is widely used in In the aluminum profile production industry. [0003] In the prior art, the extrusion chamber of the aluminum profile is surrounded by separate mold bases and material bladders, and the separation and closing of the mold bases and material bladders are controlled by corresponding oil cylinders, thereby realizing the forming of aluminum profiles. Among them, because the liner and the mold base are approached by plane contact, during the extrusion process of the aluminum profile, the aluminu...

AI Technical Summary

Problems solved by technology

Among them, because the liner and the mold base are approached by plane contact, during the extrusion process of the aluminum profile, the aluminum profile may be extruded from the gap left between the liner and the mold base. On the other hand, the plane The contact method is prone to misalignment of the material liner and the mold base, resulting in the malfunction of the aluminum profile extrusion device
