Abstract
The invention relates to a large thin-wall square tube extrusion mold, which comprises an upper mold, a lower mold, a guide hole, a mold core, a shunting bridge, a working tape and a discharge opening, wherein the upper mold is connected with the lower mold through bolts; a bridge site at a feeding opening of the guide hole sinks downwards; a plush copper which protrudes outwards is arranged at the upper end of the mold core; and the height of the top end of the plush copper is equal to or lower than the upper plane of the upper mold. The bridge site at the feeding opening of the guide hole sinks downwards, so that the height of the bridge site is reduced; the resistance is reduced; and compatible application of a high-speed extruder can be meet. The bridge site obliquely sinks downward from the outer side to the inner side, so that the strength of the bridge site is not affected. Compared with the working tape of a traditional mold, the short working tape provided by the invention is shortened by over 1/3; the stroke that an aluminum material enters the working tape is reduced; the time of the aluminum material in the working tape is shortened; the resistance is reduced; and the large thin-wall square tube extrusion mold adapts to the high-speed extruder to produce proximate matters.
Description
Technical field
The present invention relates to a kind of section bar mold, particularly relate to a kind of large thin-wall square tube extrusion die.
Background technology
Traditional its bridge location of large thin-wall square tube extrusion die is concordant with the upper side of patrix, make the height of bridge location large, the large therefore resistance of contact area of extruded aluminum and bridge location is just large, and this mould can only use, therefore under production efficiency in the low speed extruder of stub.
Object of the present invention is exactly for the problems referred to above, provides a kind of large thin-wall square tube extrusion die.
For achieving the above object, the present invention adopts following technical scheme:
A kind of large thin-wall square tube extrusion die, comprise: upper die and lower die, guide hole, core rod, shunting bridge, work strip and discharging opening, described patrix and counterdie are connected by screw, the bridge location of the feeding mouth end of described guide hole sinks downwards, the upper end of its core rod is provided with the plush copper protruded laterally, and the height on plush copper top is equal to or less than the upper plane of patrix.
Described bridge location tilts by inside lateral.
Its length of described work strip is between 5 to 10 millimeters.
Described plush copper is a part that is circular or streamlined curved surface.
The cross section of described shunting bridge is streamlined.
Guide hole is the introduction channel of charging; Shunting bridge is the dowel between guide hole, and the aluminium material entered shunting is entered die cavity by main rising.
Beneficial effect of the present invention: because the bridge location of the feeding mouth end of guide hole sinks downwards, shorten the height of bridge location, because the aluminium material of extruding and the rubbing surface of bridge location reduce, reduce resistance, supporting the use of high-speed extrusion machine can be met, because bridge location tilts by inside lateral, this design, because the upper side of bridge location is high outside and low outside inclined-plane, can not affect the intensity of bridge location, can not only meet the use of the high-speed extrusion machine that section bar is produced, mould strength is large simultaneously, not fragile; Because short work strip of the present invention shortens more than 1/3rd than traditional die working length, reduce the stroke that aluminium material enters work strip, shorten the time of aluminium material in work strip, reduce resistance, adapt to the production section bar of high-speed extrusion machine; The cross section that is streamlined and shunting bridge of up-small and down-big tapered, the plush copper of core rod is streamlinedly all considerably reduce the resistance of aluminium material by die cavity, and the high speed being conducive to aluminium material is passed through, and further increases production efficiency.

Detailed description of the invention
As shown in Figure 1 to Figure 3, the present invention includes: patrix 1, counterdie 2, guide hole 13, core rod 12, shunting bridge 11, work strip 123 and discharging opening 21, guide hole is the introduction channel of charging, and the present embodiment is provided with four guide holes; Shunting bridge is the dowel between guide hole, the aluminium material entered shunting is entered die cavity by main rising, shunting bridge cross section of the present invention is streamlined, namely cross section is that circular or close to water droplet streamlined curved surface is level and smooth, upper end can be water-drop-shaped curved surface, or a part for oval curved surface, bottom narrows in streamlined gradually, as shown in Figure 3; The bridge location of the feeding mouth end of guide hole sinks downwards, and the heavy height shortening bridge location, decreases the rubbing surface of aluminium material downwards, is conducive to improving aluminium stream speed; The upper end of core rod is provided with the plush copper 121 protruded laterally, this plush copper is a part of part on circular, taper or streamlined curved surface wherein top, feeding end resistance can be reduced like this, improve pan feeding flow velocity, the height on this plush copper top is equal to or less than the upper plane of patrix, arranges the raising that plush copper is beneficial to mould strength.
As shown in Figures 4 to 6, described bridge location tilts by inside lateral.This mould is circular, and circular periphery is outside, and be inner side by center of circle part, namely the outside of bridge location is high, at the bottom of inner side, as Figure 1 and Figure 4; Described its length of work strip 123 is between 5 to 10 millimeters.Work strip and calibrating strap, namely shaping working region, this region determines actual size and the shape of section bar, and it is consistent with the cross sectional shape of section bar.The length of traditional die working length is thick 3 to 4 times of product, land length of the present invention be product 3(as shown in Figure 6) 2.2-2.6 of thickness doubly between.Because the shortening of work strip, aluminium stream dynamic resistance reduces, and flow velocity can increase, and this mould adapts to the use of high speed profile extruder.
