Abstract

The invention relates to a large-scale solid profile hot extrusion mould of a medium extruder, formed by orderly laying up a front guide plate (1), a secondary guide plate (2) and a mould surface (3)from front to back. The front guide plate (1) comprises a first center material inlet hole (11), and the upper hole wall and the lower hole wall of the first center material inlet hole (11) consist ofa front straight hole wall (111) and a back inclined hole wall (112), the back inclined hole wall (112) is gradually extended from front to back, the left hole wall (113) and the right hole wall (113) form an inclined hole wall shape, and the inclined hole wall is gradually extended. The secondary guide plate (2) comprises a second center material inlet hole (21), and the second center material inlet hole (21) is in a dumbbell shape. The center part of the second center material inlet hole (2) is adjacent to a mould cavity of the mould surface, and the left end and the right end are extended.The mould surface (3) comprises a guide pit (31) and the mould cavity (32), the upper pit wall (311) and the lower pit wall (311) form an inclined surface shape, and the inclined surface is tapered.The invention can guarantee the sufficient material supply of large-scale solid profile angle positions, can effectively increase extruding force, and guarantee the density and the strength of profiles.

Description

Large-scale solid profile hot extrusion mould on the medium-sized extruder

(1) technical field

The present invention relates to a kind of mould, be specifically related to the large-scale solid profile hot extrusion mould on a kind of medium-sized extruder.Belong to aluminum alloy extrusion section bar mold machining technology field.

(2) background technology

Because to have density little for aluminum alloy extrusion section bar, the intensity height, processing easily, maintenance and maintenance property are simple, and have many advantages such as good and economic, the feature of environmental protection and recuperability, so aluminum alloy extrusion section bar is in the application of every field more and more widely.Originally many large-scale primary structure members also replace steel with aluminium alloy gradually.Because at present domestic large-size extruder is also few, many large-scale solid profiles are just had to be placed on the medium-sized extruder and are pushed.Because this large-scale solid profile sectional area is big, the rice of section bar is heavy very heavy, on medium-sized extruder, push, extrusion ratio is very little, have only 3-4 under a lot of situations, as shown in Figure 1, make position, the angle feed difficulty of section bar, the angle of collapsing, the position, section bar angle that extruding is come out, even big circular arc is come out to become in the position, angle.Because extrusion ratio is little, extruding force is not enough, and section bar density and intensity that extruding is come out are difficult to reach requirement, and the section bar of extruding all is cast sturcture rather than extrusion tissue.

(3) summary of the invention

The objective of the invention is to overcome above-mentioned deficiency, provide a kind of and can guarantee position, large-scale solid profile angle feed abundance, having effectively to increase extruding force, the large-scale solid profile hot extrusion mould on the density of assurance section bar and the medium-sized extruder of intensity.

The present invention solves the technical scheme that its technical barrier adopts: the large-scale solid profile hot extrusion mould on a kind of medium-sized extruder is formed by stacking by preposition deflector, secondary deflector and die face successively from A-P;

Described preposition deflector, comprise first central well, this first central well two hole walls up and down is made up of leading portion straight hole wall and back segment inclined hole wall two parts, and back segment inclined hole wall is the flaring shape from A-P, two hole walls are inclined hole wall shape about this first central well, and this inclined hole wall is the flaring shape;

Described secondary deflector comprises second central well, and this second central well is dumbbell shaped, and the die cavity of die face is pressed close in the centre of this second central well, and two ends, the left and right sides enlarge;

Described die face comprises water conservancy diversion hole and die cavity, and the wall of hole up and down in this water conservancy diversion hole takes the form of inclined plane, and this inclined-plane is gradually-reducing shape, the obstruction angle of formation die cavity work zone.

The invention has the beneficial effects as follows:

The present invention adopts two deflectors, has increased aluminium alloy and has arrived the distance that the die face water conservancy diversion is cheated, and has increased extruding force.Preposition deflector adopts core to block the feeding manner of formula, reduces the area of central well, strengthens the charging area at two ends.Flow velocity in the middle of so just helping controlling, the feed of increasing two ends and position, angle guarantees the size that the position, angle is pushed out.Simultaneously can also effectively increase extruding force, the density and the intensity of the section bar that assurance pushes out.The secondary deflector adopts the feeding manner of dumb-bell shape, and the die cavity of die face is pressed close in the centre, and two ends enlarge, the flow velocity of the core that further slowed down and the feed abundance that has guaranteed two ends and position, angle.Adopt the mode of deepening the water conservancy diversion hole to increase the extruding force of mould on the die face; The mid portion work zone of section bar increases the slow down flow velocity of core of the mode that hinders the angle.Solve large-scale solid profile to occur the position, angle on medium-sized extruder easily under feeding thereby reach, circle of position angle, section bar angle, the purpose of density and undercapacity.
