Abstract
The present invention relates to hot extruding mold for aluminum profile of fin inserting heat radiator. The hot extruding mold consists of front guide plate, guide plate and mold face. The front guide plate has two inclined expanding guide ports, the guide plate has expanding guide port in the material feeding end and straight guide port in the discharge end, and the mold face has guide notch in the same shape as the straight guide port in the discharge end of the guide plate. The present invention can perform three pre-deformations of different properties to facilitate the production of aluminum profile of fin inserting heat radiator.
Description
Technical field:
The present invention relates to a kind of hot-extrusion mold, especially relate to a kind of hot-extrusion mold of gear shaping sheet heat radiator aluminium profile.Belong to the radiator technical field of mold.
Background technology:
As everyone knows, radiator class hot-extrusion mold is a big difficult point of die industry.Particularly excessive, the tongue of wall thickness great disparity than excessive, circumscribed circle is excessive, factor such as complex-shaped causes the mould molding difficulty, instability, problem such as output is few makes radiator class hot-extrusion mold scrappage be higher than common die far away.And gear shaping sheet heat radiator section bar (seeing Figure 12) trends towards that wall thickness great disparity is big, tooth is close, the shape prolate, exceed the big four major problem of aluminium bar scope.Improve the prouctiveness of this aluminium section bar, must not solve this four major problem from mould earlier.
According to known to, because of not solving the strength problem of flat recipient well, all be circular when the employed recipient of aluminium section bar plant is most, gear shaping sheet section material section then is the prolate type, this is that predeformation has caused many difficulties for the first time, and also bigger to the pressure of mould.
Because predeformation, pressurized precompressed, flow control are all improved on preposition deflector, so the design of preposition deflector is the key of mould.We know that under same condition, the areal pressure away from the extrusion die center is more little more, and flow is more little, and particularly the zone beyond the aluminium bar is difficult to charging especially.The design of described preposition deflector must be adjusted the charging area according to different zones.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, a kind of hot-extrusion mold of the gear shaping sheet heat radiator aluminium profile that can grasp the predeformation first time well, more effectively reduce pressure, process more easily is provided.
The object of the present invention is achieved like this: a kind of hot-extrusion mold of gear shaping sheet heat radiator aluminium profile, it is characterized in that it is formed by stacking by preposition deflector, deflector and die face front and back,
Described preposition deflector, its flow-guiding mouth both sides are inclined push type expansion flow-guiding mouth,
Described deflector, the feed end of its flow-guiding mouth are the expanded type flow-guiding mouth, and discharge end is for directly leading the type flow-guiding mouth,
Described die face, the water conservancy diversion hole shape of its feed end is consistent with the shape of the flow-guiding mouth of deflector discharge end.
The hot-extrusion mold of gear shaping sheet heat radiator aluminium profile of the present invention, described preposition deflector, its flow-guiding mouth central authorities are the taper flow-guiding mouth.
The hot-extrusion mold of gear shaping sheet heat radiator aluminium profile of the present invention, addition has die-cushion after the described die face.
The inclined push type of the preposition deflector of the present invention expansion flow-guiding mouth partly flows to the aluminium section bar of flow path in it by axially changing into radially with feed demand that both sides are provided to accelerate the charging rate at section bar two ends, again by the type of directly the leading flow-guiding mouth that goes out charge level of deflector partly radial flow to making axial flow into to alleviate the side pressure of fluid, at last by the partly excessive regional transition adjustment of flow great disparity of gradual-enlargement type water conservancy diversion hole, both sides of die face to the little tooth of die face.
The present invention is the addition deflector between preposition deflector and die face, has alleviated the burden of preposition deflector like this, and mould of the same type can exchange guide plate easily.Die face water conservancy diversion hole adopts the flaring mode to enlarge the right and left not only to have slowed down the local excessive pressure of die face but also easily processing and attractive in appearance.
The present invention in the water conservancy diversion process through three predeformation of different nature, solve that gear shaping sheet heat radiator aluminium profile wall thickness great disparity is big, tooth is close, the shape prolate, exceed the big four problems of aluminium bar scope, thoroughly solved the difficulty of gear shaping sheet heat radiator aluminium profile on producing.

The specific embodiment:
Referring to Fig. 1,2, the hot-extrusion mold of gear shaping sheet heat radiator aluminium profile of the present invention is formed by stacking by preposition deflector 1, deflector 2, die face 3 and die-cushion 4 successively from A-P.Preposition deflector 1 links to each other with deflector 2 usefulness screws 5, pin 9, and deflector 2 links to each other with die face 3 usefulness screws 7, pin 8, and die face 3 is connected with die-cushion 4 usefulness pins 6,
Referring to Fig. 3,4,5, described preposition deflector 1, its flow-guiding mouth 11 central authorities are taper flow-guiding mouth 111, both sides are inclined push type expansion flow-guiding mouth 112.
Referring to Fig. 6,7, described deflector 2, the feed end of its flow-guiding mouth 21 are expanded type flow-guiding mouth 211, and discharge end is for directly leading type flow-guiding mouth 212.
Referring to Fig. 8,9, described die face 3, it is consistent with the shape of the flow-guiding mouth 212 of deflector 2 discharge ends that the water conservancy diversion of its feed end is cheated 31 shapes.Die face discharge opening 32 among the figure, die cavity 33.
Referring to Figure 10,11, described die-cushion 4, addition is in die face 3 rear sides.Among the figure: die-cushion discharge opening 41.
