Abstract
The invention discloses an aluminum alloy hot extrusion mold for producing a hooked rabbet section. The mold consists of an upper mold and a lower mold abutting each other. An indented welding chamber is arranged in the middle of a feed surface of the lower mold. A cavity and a discharge hole are formed between the welding chamber and the discharge end of the lower mold. The cavity comprises a cavity hook body and a cavity body. A cantilever is formed between the cavity hook body and the cavity body. A raised choke block is arranged in the welding chamber. The choke block is arranged on the top of the cavity hook body. Four bridge locations are radially formed in the middle of the feed surface of the upper mold. Four diffluent holes are formed between the bridge locations. A mold core stretching into the cavity of the lower mold is mounted at the intersection of the four bridge locations. The mold can enable the cantilever to avoid directly suffering from the pressure from molten aluminum in the extrusion press and being flushed away by the molten aluminum. Meanwhile, the speed of the molten aluminum entering the cavity hook body can be slowed down, such that the speed of the molten aluminum entering the cavity hook body is consistent with that of the molten aluminum entering the cavity body. The quality of the produced section is good. The mold has long service life and is mainly used for producing a hooked rabbet section of aluminum alloy door and window.
Description
Technical field
The present invention relates to aluminium alloy hot-extrusion die technical field, especially a kind of aluminium alloy hot-extrusion die for the production of Hooked rabbet profile.
Background technology
At present, the hot-extrusion mold of producing aluminum alloy tongue-and-groove section bar is made up of upper die and lower die docking, in the middle of the charging face of counterdie, be provided with the seam chamber of indent, seam chamber is provided with die cavity and discharge opening between counterdie discharge end, die cavity includes die cavity and hooks body and die cavity main body, and die cavity hooks between body and die cavity main body and is formed with cantilever; The charging face intermediate radial of patrix is provided with four bridge locations, forms four tap holes between bridge location, and the intersection of four bridge locations is provided with the core rod that stretches into counterdie die cavity.There is following defect in the hot-extrusion mold of this traditional structure: it is poor that (1) die cavity hooks the cantilever bearing capacity forming between body place and die cavity main body, easily occurs squeeze partially or subside while directly impacted by aluminium water, causes mould to scrap too early; (2) the hook body thickness on hook frame body sectional material is greater than the thickness of section bar main body, and in the process of extrusion molding, the aluminium water that enters die cavity hook body is faster than the aluminium water speed that enters die cavity main body, easily causes the wall unevenness of section bar even.Therefore, designing a kind of aluminium alloy hot-extrusion die that can address the above problem well is extremely necessary.
Summary of the invention
Object of the present invention is improved for the deficiencies in the prior art exactly, provides one to protect preferably cantilever, guarantees all even accurate in size aluminium alloy hot-extrusion dies of aluminium section bar wall thickness.
Concrete scheme of the present invention is: the aluminium alloy hot-extrusion die for traditional mode of production Hooked rabbet profile improves, it is made up of upper die and lower die docking, in the middle of the charging face of counterdie, be provided with the seam chamber of indent, seam chamber is provided with die cavity and discharge opening between counterdie discharge end, die cavity includes die cavity and hooks body and die cavity main body, and die cavity hooks between body and die cavity main body and is formed with cantilever; The charging face intermediate radial of patrix is provided with four bridge locations, forms four tap holes between bridge location, and the intersection of four bridge locations is provided with the core rod that stretches into counterdie die cavity; It is characterized in that: described seam is indoor is provided with protruding choker bar, this choker bar is arranged at die cavity and hooks the top at body place.
Described in the present invention, the inner hole surface of four tap holes is the bell mouth shape expanding outwardly.
Described in the present invention, discharge opening is stepped.
The cross section of choker bar described in the present invention is at right angles trapezoidal, and the oblique waist of right-angled trapezium is upper, right angle waist under; The upper base a of right-angled trapezium is 4mm, and high h is 2.5mm.
The present invention arranges a choker bar seam is indoor, bring following benefit: (1) choker bar can change the flow direction of aluminium water, avoid the direct impact mold cavity of aluminium water to hook the cantilever between body place and die cavity main body, can effectively stop cantilever squeezed partially or the hidden danger of subsiding, greatly extend the service life of mould; (2) choker bar can slow down the aluminium water speed that enters die cavity hook body, and the aluminium water speed that enters die cavity hook body is reached unanimity with the aluminium water speed that enters die cavity main body, and the section bar wall thickness of producing is like this even, and quality is comparatively desirable.
