Abstract
The utility model relates to an automobile cooling pipe aluminum profile heat extrusion die which is mainly used for heat extrusion of automobile fittings aluminum alloy profiles and consists of an upper die (1) and a lower die (2) which are assembled. The utility model is characterized in that a bridge site (5) is arranged in the middle of a feeding end of the upper die (1); two shunting holes (6) are arranged on two sides of the bridge site (5) and the shunting holes (6) expand towards two sides to form shunting hole expansion sites (7). A die core (4) is arranged in the middle of a discharging end of the upper die (1), and the die core (4) is equally and obliquely bridged and connected with the bridge site (5) to form an inversed bridge site, and the bridge site inverse-angle Alpha is between 7 and 12 degrees. The middle part of the feeding end of the lower die (2) is depressed to be provided with a seaming chamber (3) with a height between 3 and 4mm. The automobile cooling pipe aluminum profile heat extrusion die can result in equal metal flow and a stable die core, not only satisfying the feeding requirement by middle inner teeth of profile but also guaranteeing the accuracy of size and quality of inner and outer surfaces of the profile.
Description
Technical field
The utility model relates to a kind of automobile cooling pipe aluminium section hot-extrusion die.Be mainly used in the hot extrusion of auto parts machinery aluminium alloy extrusions.Belong to the mold machining technology field.
Background technology
Along with the growth requirement of Hyundai Motor industry, aluminium alloy extrusions is used more and more widely in automobile industry, thereby more and more higher to the quality requirement of aluminium alloy extrusions, as: the surface quality of aluminium alloy extrusions, dimensional accuracy, hardness etc.But there are many weak points in the mould of such section bar of processing (as Fig. 7) at present, as:
1, metal flow is unbalanced, and the section bar endoporus profile of tooth of production is unintelligible, section bar band muscle surface of position injustice;
2, core rod instability, the easy beat of patrix core rod, fracture;
3, mould production pressure is big, yielding, the cracking of mould.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of feed that makes metal flow equilibrium, core rod stablize, can satisfy the middle internal tooth of section bar to require, can guarantee again the automobile cooling pipe aluminium section hot-extrusion die of section bar surfaces externally and internally quality and dimensional accuracy.
The purpose of this utility model is achieved in that a kind of automobile cooling pipe aluminium section hot-extrusion die, is combined by upper die and lower die, it is characterized in that:
Be provided with a bridge location in the middle of the described patrix feed end, the bridge location both sides are furnished with two tap holes, and expansion forms tap hole expansion place to tap hole to both sides; Be provided with a core rod in the middle of the patrix discharge end, core rod and bridge location evenly tiltedly the transition formation bridge location that links to each other fall bridge, the bridge location angle of falling bridge α gets 7 °～12 °,
Be concaved with the seam chamber downwards in the middle of the described counterdie feed end, seam chamber height is got 3～4mm.
The utility model automobile cooling pipe aluminium section hot-extrusion die, the drainage trough at the little tooth of described core rod position is machined directly to the position, and intermediate ribs is processed empty cutter, does not process drainage trough.
Compare with existing similar mould, the utlity model has following advantage:
1, patrix core rod and bridge location even transition, the bridge location angle of falling the bridge are got 7 °～12 °, are 1/3rd (common die is generally 30 °～45 °) of common die, have so just guaranteed the feed of core rod, have also reduced the extruding force to mould simultaneously.
2, counterdie seam chamber height is got 3～4mm, (is generally 10～13mm), has so just strengthened the intensity and the stability of core rod than common die is much lower.
3, the drainage trough at the little tooth of core rod position is directly put in place by the line cutting processing, and intermediate ribs is not processed drainage trough by the empty cutter of line cutting processing, so both can guarantee the feed of core rod, has increased the intensity of core rod simultaneously.
By above-mentioned improvement, the utility model can make the metal flow equilibrium, and core rod is stable, can satisfy the feed requirement of the middle internal tooth of section bar, can guarantee section bar surfaces externally and internally quality and dimensional accuracy again.

The specific embodiment
Referring to Fig. 1～2, the utility model is a kind of automobile cooling pipe aluminium section hot-extrusion die, is combined by patrix 1 and counterdie 2.
Referring to Fig. 3～4, be provided with a bridge location 5 in the middle of described patrix 1 feed end, bridge location 5 both sides are furnished with two tap holes 6, and expansion forms tap hole expansion place 7 to tap hole 6 to both sides; Be provided with a core rod 4 in the middle of patrix 1 discharge end, core rod 4 and bridge location 5 evenly tiltedly the transition formation bridge location that links to each other fall bridge, the bridge location angle of falling bridge α gets 7 °～12 °, the drainage trough at the little tooth of core rod position is directly put in place by the line cutting processing, intermediate ribs is by the empty cutter of line cutting processing, do not process drainage trough, so both can guarantee the feed of core rod, increased the intensity of core rod simultaneously.
Referring to Fig. 5～6, be concaved with seam chamber 3 downwards in the middle of described counterdie 2 feed ends, 3～4mm is highly got in seam chamber 3.
