Abstract
The invention relates to a solid aluminum hot extrusion mould with greatly different wall thickness and provided with a cantilever and is mainly used for the hot extrusion of solid aluminum profile. The mould is formed by the assembly and combination of a fronting diversion mold (1) and a section mold (2), a front feeding chamber (1.1) of the fronting diversion mold (1) is convexly provided with acantilever type bridge (1.2) which extends out of the inner edge of the front feeding chamber (1.1) from the middle of the front feeding chamber (1.1), the ends of the cantilever type bridge (1.2) exceed the middle position of the front feeding chamber (1.1), the end surface of the cantilever type bridge (1.2) close to the feeding position of the fronting diversion mold (1) is an inclined plane,the end surface close to the discharge position of the fronting diversion mold is provided with a convex plate (1.3) towards the discharging direction, the bottom end surface of the mold cavity (2.2)of the section mold (2) is convexly provided with a flow-blocking plate (2.1) towards the feeding direction of the section mold, and the flow-blocking platform (2.1) is arranged outside the cantilever(2.4) of the section mold. The mould can extrude the solid aluminum with greatly different wall thickness and provided with the cantilever.
Description
(1) technical field
The present invention relates to a kind of hot-extrusion mold.Be mainly used in the hot extrusion of solid aluminium.Belong to the mold machining technology field.
(2) background technology
Along with current socioeconomic developing rapidly, the advantage of aluminum alloy materials is generally acknowledged that by the world its application is more and more widely, and much other material is all progressively substituted by it, and is also more and more higher to the requirement of its product quality certainly.The user of alloy product is in order constantly to reduce cost, and a lot of aluminium products all require directly extruding to come out, and do not need through follow-up deep-processing process, have brought unprecedented challenge so just for aluminium section bar manufacturer.Wherein extrusion process is an important link, but the still Mould design and the manufacture level of most critical, the success or not of its quality decision aluminium product.The size that present most product has does not also reach requirement, the shape instability that has, have in addition can't be shaped.Various schemes are all being groped by many producers on these problems, but immature.
The mould that is used for the solid aluminium of hot extrusion at present mainly has the following disadvantages: mould does not adopt preposition water conservancy diversion mould, and the water conservancy diversion of mould and die cavity are one, has reduced the feed of die cavity.Therefore can not squeeze out the solid aluminium that wall thickness differs greatly and is with cantilever.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of and can squeeze out the hot-extrusion mold that wall thickness differs greatly and is with the solid aluminium of cantilever.
The object of the present invention is achieved like this: a kind of wall thickness differs greatly and is with the solid aluminum material hot-extrusion mold of cantilever, it is characterized in that described mould is formed by preposition water conservancy diversion mould and pattern assembly,
The indoor protrusion of preceding charging of described preposition water conservancy diversion mould is provided with Cantilever Bridges, these Cantilever Bridges are stretched out by the advance center of material chamber of the interior cause of feed space before described, the end of these Cantilever Bridges exceeds the center of described preceding feed space, these Cantilever Bridges take the form of inclined plane near the end face of preposition water conservancy diversion mould charging place, end face near discharging place of preposition water conservancy diversion mould is write out a prescription to being provided with a boss to described discharging
Be provided with a choked flow platform to pattern feedstock direction protrusion on the die cavity bottom face of described pattern, this choked flow platform is arranged at the outside, cantilever place of described pattern.
Compare with existing similar mould, mould of the present invention has following characteristics:
1, mould adopts preposition water conservancy diversion mould, and water diversion part and typing are partly separated, and changing mould water conservancy diversion and die cavity is the conventional structure of one, increases the feed of die cavity.
2, the water conservancy diversion mould adopts outrigger formula structural design, and a boss is stayed at the place at the section bar heavy wall, can better control the feed at section bar heavy wall place like this, nor can resemble the bridge type structure aluminium product is produced the seam seam.
3, arranged outside one choked flow platform in pattern cantilever place causes the cantilever beat with the side that prevents aluminium water.

(5) specific embodiment
Referring to Fig. 1～2, the wall thickness that the present invention relates to differs greatly and is with the solid aluminum material hot-extrusion mold of cantilever, is formed by preposition water conservancy diversion mould 1 and pattern 2 usefulness pins 3 and screw 4 assemblies.
Referring to Fig. 3～4, the preceding feed space 1.1 projecting inward Cantilever Bridges 1.2 that are provided with of described preposition water conservancy diversion mould 1, these Cantilever Bridges 1.2 are stretched out by the advance center of material chamber 1.1 of the interior cause of feed space 1.1 before described, the end of these Cantilever Bridges 1.2 exceeds the center of described preceding feed space 1.1, these Cantilever Bridges 1.2 take the form of inclined plane near the end face of preposition water conservancy diversion mould charging place, write out a prescription to being provided with a boss 1.3 to described discharging near the end face of preposition water conservancy diversion mould discharging place.
Referring to Fig. 5～6, be provided with a choked flow platform 2.1 to pattern feedstock direction protrusion on die cavity 2.2 bottom faces of described pattern 2, this choked flow platform 2.1 is arranged at 2.4 outsides, cantilever place of described pattern 2.Make the section bar extrusion modling by die cavity 2.2, send by discharging opening 2.3.
