Abstract

The utility model relates to an aluminum profile die with a front guide hole. The aluminum profile die comprises an upper die, a lower die, a guide hole, a die core, a working tape, a feeding hole and a discharge opening, wherein the guide hole is formed in the feeding hole; the upper die and the lower die are connected through a screw; the aluminum profile die is characterized by also comprising a front guide hole; the front guide hole is a concave hole; the concave hole is recessed into the rear side of the die from the front end of the upper die; the surface of an inner side wall of the front guide hole which corresponds to the front of the guide hole is gradually enlarged from the front end to the rear outer side and is in smooth communication with an outer side wall of each guide hole. The pressure in an extrusion die is greatly reduced, and because the hole section is gradually enlarged after an extruded material enters the die, the pressure of the extruded material in the die is reduced. Compared with a traditional die, the aluminum profile die has the advantages that the pressure in the die is generally reduced by over 30 percent, the die is durable due to reduction of the pressure of the die, the production cost is reduced, and high-quality profile products are easily extruded.

Description

A kind of aluminium section die with front guide hole

Technical field

The utility model relates to a kind of section bar mold, particularly relates to a kind of aluminium section die with front guide hole.

Background technology

The charging aperture of each guide hole of traditional extruding die for aluminum shaped material is in the plane of mould front end, this mould is generally used for the small-sized aluminium section bar of extruding, for large-scale aluminium section bar, adopt this mould to increase difficulty, require to be equipped with larger extrusion equipment, with larger pressure extrusion, just can embark on journey, by reason of heavy pressure, mould easily damages, and service life is short.

Summary of the invention

The purpose of this utility model is exactly for the problems referred to above, and a kind of aluminium section die with front guide hole is provided.

For achieving the above object, the utility model adopts following technical scheme:

A kind of aluminium section die with front guide hole, comprise: upper die and lower die, guide hole, core rod, work band, charging aperture and discharging opening, in charging aperture, be provided with guide hole, between described patrix and counterdie, be connected by screw, it is characterized in that: also comprise a front guide hole, described front guide hole is a shrinkage pool, this shrinkage pool is recessed to mould rear by the front end of patrix, and front guide hole interior sidewall surface corresponding to guide hole the place ahead expands gradually from the rearward outside of front end, and is smoothly communicated with the lateral wall of each guide hole.

The angle of the front guide hole lateral wall that described guide hole lateral wall is corresponding with guide hole the place ahead is between 15 degree to 42 degree.

The degree of depth of described front guide hole be the guide hole degree of depth 1/3rd to 1/5th between.

The angle of the front guide hole outer side surface that between described guide hole, the anterior face of sidewall is corresponding is 90 degree.

The beneficial effects of the utility model: because the front portion of patrix is provided with front guide hole, and front guide hole madial wall corresponding to guide hole the place ahead expands and is smoothly communicated with the lateral wall of each guide hole laterally gradually backward from front end, pressure in extrusion die is significantly reduced, because entering mould metapore cross section, pressing material progressively increases, the pressure of pressing material in mould reduces, compare general attenuating mould inner pressure with traditional moulds more than 30%, due to reducing of die pressure, mould is more durable, reduced production cost, more easily extrude the section bar product of good quality, this mould is specially adapted to the extruding of large aluminum profile, and can squeeze out the section bar product of thin-walled, because front guide hole is a shrinkage pool, the area of section of front guide hole is progressively expanded, in extrudate, the pressure of mould medium section, by progressively reducing to enter in the guide hole in mould greatly, makes the material operation of extruding more smooth steadily, more easily guarantees product quality, because the angle of the guide hole lateral wall front guide hole lateral wall corresponding with guide hole the place ahead is between 15 degree to 42 degree, can select suitable front guide hole reaming angle according to the size of extrudate and extrusion equipment situation, make the easier moulding of extruding of large scale section bar, and lowered difficulty, because traditional moulds needs larger extruding force just can accomplish, and the required pressure decreased of the utility model mould, because front guide hole and patrix are connected as a single entity, make seamless link between front guide hole and guide hole, connect more easily level and smooth, reduce crush resistance, before and after mould, size is shorter simultaneously, saves mold materials, reduce mold weight, reduce Mold Making difficulty, installing/dismounting is more convenient, because the angle of front guide hole outer side surface corresponding to the anterior face of sidewall between guide hole is 90 degree, make front guide hole be difficult for distortion, guaranteed the intensity of mould.

Number description: 1. patrix; 2. counterdie; 11. front guide holes; 12, guide hole; 13 core rods; 14. guide hole sidewalls; The angle of the front guide hole outer side surface that the anterior face of 15. sidewalls is corresponding; The angle of the front guide hole lateral wall that 16. guide hole lateral walls are corresponding with guide hole the place ahead; 21. discharging openings; 22.. the band of working; 23 pressing material hybrid chambers.

The specific embodiment

As shown in Figures 1 to 5, the utility model comprises: patrix 1, counterdie 2, guide hole 12, core rod 13, work are with 22, charging aperture 111, discharging opening 21 and front guide hole 11, in charging aperture, be provided with guide hole, between described patrix and counterdie, be connected by screw, described front guide hole 11 is a shrinkage pool, this shrinkage pool is recessed to mould rear by the front end of patrix, and front guide hole interior sidewall surface corresponding to guide hole the place ahead expand gradually from the rearward outside of front end, and is smoothly communicated with the lateral wall of each guide hole 12.The front end of front guide hole is charging aperture 111.

The angle 16 of the front guide hole lateral wall that described guide hole 12 lateral walls are corresponding with guide hole the place ahead is between 15 degree to 42 degree, before, guide hole is only provided with angle with the sidewall of the junction of guide hole, this angle instruct hole sidewall extended line forward with corresponding before the angle of guide hole sidewall, namely by charging aperture, to guide hole lateral wall place, progressively expanded gradually, the face of institute's reaming is exactly the side wall surface of front guide hole corresponding to guide hole the place ahead, as shown in Fig. 2, Fig. 5, this side wall surface 17 sees that from cross section the section line of reaming can be straight line or curve.The degree of depth of described front guide hole 11 is exactly the size that charging aperture is recessed to mould, this degree of depth be the guide hole degree of depth 1/3rd to 1/5th between.Between described guide hole, the angle 15 of the front guide hole outer side surface 18 of anterior face 14 correspondences of sidewall is 90 degree, and this design can guarantee the intensity at charging aperture place, also makes pressing material enter more smoothly mould simultaneously.
