Abstract
The utility model relates to a split type hot extrusion die mainly used for the hot extrusion of high cantilever decorating aluminum profile of windows and doors. The hot extrusion die comprises an upper die (1) and a lower die(2), wherein, two relief-holes (1.1) are symmetrically arranged on the feed surface of the upper die (1), and a relief-bridge (1.2) is formed between the two relief-holes (1.1); a die core (1.3) which is protruded downwards is arranged in the middle of the discharge surface of the upper die (1), and a die core split inclined plane (1.3.1) is arranged at the juncture of one side of the die core (1.3) and the top end surface; a welding chamber (2.1) is arranged on the feed surface of the lower die (2), and a die cavity (2.2) is arranged at the back of the welding chamber (2.1); a die cavity inclined plane (2.2.1) is arranged on the cavity wall part corresponding to the die core split inclined plane (1.3.1) of the upper die and the die cavity (2.2); and the die cavity inclined plane (2.2.1) is matched with the die core split inclined plane (1.3.1) of the upper die in a seamless way to form an inclined split opening; and a gap which is one wall wide is respectively reserved on the other matching surfaces between the die cavity (2.2) and the die core (1.3) of the upper die. The utility model can overcome the deflection and fracture problems of the cantilever part of the lower die of the hot extrusion die.
Description
(1) technical field
The utility model relates to a kind of aluminium section hot-extrusion die.Be mainly used in the high cantilever of door-window kind and decorate the hot extrusion of using aluminium section bar.Belong to the mold machining technology field.
(2) background technology
Along with the development of Modern Decorative industry, also more and more higher to the requirement of ornament materials.The quick shaping of aluminium alloy under extruding, and aluminium alloy just highlights the advantage of aluminium alloy when using as ornament materials in these characteristics that can obtain high intensity after the heat treatment.But in Decorative door and window class material, some tops, below class sash stuff arm length, opening little (as Fig. 7).When this class aluminium alloy extrusions of extruding,, its intrinsic profile nature (arm length, opening is little) in use is easy to damage because of making extrusion die.Analyzing its reason is mould lifting surface area big (arm length), support strength little (opening is little).Bearing powerful extruding force bed die bracketed part beat even rupturing from opening part.The beat of bracketed part causes the wall unevenness of section bar and fracture and the mould that causes is scrapped, and has improved the production cost and the production cycle of this class ornament materials widely.Trace it to its cause, be because: the patrix core rod of mould and counterdie die cavity cooperation place all are open type, the design of opening will on be molded as flat-die type powdered.The support force of section bar opening portion is reduced greatly.Aluminium enters counterdie through the shunting of patrix tap hole, acts directly on the counterdie bracketed part and forms powerful extruding force, and is very big to the impact of bracketed part, causes the beat and the fracture of counterdie bracketed part.
(3) summary of the invention
The purpose of this utility model is to overcome the beat of lower mould bracketed part and the problem of fracture, and the assembly mouth formula hot-extrusion mold of the aluminium section bar of the high cantilever ratio of a kind of energy High-efficient Production is provided.
The purpose of this utility model is achieved in that a kind of assembly mouthful formula hot-extrusion mold, comprise upper die and lower die, described patrix charging is in the face of claiming to be furnished with two tap holes, form a shunting bridge between two tap holes, the downward protrusion was provided with a core rod in the middle of patrix went out charge level, one side of this core rod and the design of top end face intersection have core rod to piece together a mouthful inclined-plane, described counterdie charging face is provided with the seam chamber, seam is provided with die cavity behind the chamber, described die cavity is pieced together the corresponding chamber wall part design in mouthful inclined-plane with the core rod of patrix has die cavity to piece together a mouthful inclined-plane, this die cavity assembly mouthful inclined-plane is seamless cooperation when cooperating with the core rod assembly mouthful inclined-plane of patrix, form and tiltedly piece together mouth, other mating surface of described die cavity and patrix core rod all leaves a wall thickness gap.
The oblique assembly mouth of the utility model design has changed mould structure effectively, original opening part is changed into piece together a mouthful place, and the support force of opening portion is improved greatly; The design of piecing together mouth partly changes original flat-die into the divergent die part, and aluminium is through the shunting of patrix mould bridge and enter mould, has therefore changed the acting surface of power.Originally the powerful extruding force that acted directly on the counterdie bracketed part is affacted above the patrix.Avoided the impact of extruding force effectively to bracketed part.Flat-die as compared with the past designs and prevents that cotter pin nail design advantage is obvious.Because changed mould structure, the characteristics that the long cantilever of aluminium section bar and opening are little have not just existed on mould, just can not cause the beat and the fracture of bracketed part.Improve the section bar output of single mold widely, thereby reduced die cost; Beat and the profile size problem that causes have not just existed yet, and have improved the yield rate of section bar, have reduced waste product.

Among the figure: patrix 1, counterdie 2; Tap hole 1.1, shunting bridge 1.2, core rod 1.3, core rod are pieced together a mouthful inclined-plane 1.3.1, seam chamber 2.1, die cavity 2.2, a die cavity assembly mouthful inclined-plane 2.2.1.
(5) specific embodiment
Referring to Fig. 1～2, the assembly mouth formula hot-extrusion mold that the utility model relates to is formed by stacking by patrix 1 and counterdie 2 front and back, and is middle with two screws and two pin assemblings (close-fitting).
Referring to Fig. 3～4, described patrix 1 charging is in the face of claiming to be furnished with two tap holes 1.1, form a shunting bridge 1.2 between two tap holes 1.1, the downward protrusion was provided with a core rod 1.3 in the middle of patrix 1 went out charge level, and a side of this core rod 1.3 and the design of top end face intersection have core rod to piece together a mouthful inclined-plane 1.3.1.This inclined-plane is best for 30 °.
Referring to Fig. 5～6, described counterdie 2 charging faces are provided with seam chamber 2.1, be provided with die cavity 2.2 behind the seam chamber 2.1, described die cavity 2.2 is pieced together the corresponding chamber wall part design of mouthful inclined-plane 1.3.1 with the core rod of patrix has die cavity to piece together a mouthful inclined-plane 2.2.1, this die cavity assembly mouthful inclined-plane 2.2.1 is seamless cooperation when cooperating with the core rod assembly mouthful inclined-plane 1.3.1 of patrix, form and tiltedly piece together mouth, described die cavity 2.2 all leaves a wall thickness gap with other mating surface of patrix core rod 1.3.
