Abstract

The utility model relates to a one-die-multi-core extrusion die comprising an upper die, a lower die and a glut. The upper die comprises a deflector and a melding chamber; the deflector is provided with a plurality of shunt holes; the melding chamber is arranged at the lower part of the shunt holes; the lower die and the glut are tightly embedded together; the glut is provided with a deflector pit which is communicated with the melding chamber and provided with a forming hole with a cross section in the same shape with the cross section of an aluminum alloy profile; and the lower part of the forming hole is communicated with a working tape. A plurality of gluts can be arranged on one die according to the requirement of different wall thicknesses so as to be replaced as required. The utility model effectively shortens the production period of the die and decreases the economic cost.

Description

One mould multicore extrusion die

One, technical field: the utility model relates to a kind of mould, is specifically related to the employed mould multicore extrusion die of a kind of production extrudate.

Two, background technology: the existing mould of producing aluminium alloy extrusions mainly is made of patrix and die-cushion two parts, and different wall thickness need be developed many molds, and after a whole set of mould was scrapped, special steel utilized low, when needing the making new die cycle long, the expense height.

Three, summary of the invention: the purpose of this utility model just provides a kind of extrusion die of more timing-saving and economic.

This mould multicore extrusion die comprises upper die and lower die and three parts of inserting, and patrix is made of deflector, seam chamber.Have several tap holes on the described deflector, the seam chamber is arranged on the bottom of tap hole; Described counterdie closely is embedded in inserting, and inserts to be provided with the water conservancy diversion hole, and the water conservancy diversion hole communicates with the seam chamber; Water conservancy diversion is processed with the shaped hole identical with the aluminium alloy extrusions cross sectional shape in the hole, and the shaped hole bottom is connected with the work zone; One mold can require a plurality of the inserting of configuration according to different wall, so that change at any time.

Described tap hole can be provided with 2-10.

The shape of the described shaped hole of going up processing inserted can be respectively with banding, that horizontal, flat any section bar cross sectional shape sliding, in gliding, closing up identical admittedly, thereby form mould series.

Described inserting can be changed according to the section bar wall thickness of any section bar cross sectional shape or needs, not only fast but also economical.

The utility model compared with prior art has following characteristics: 1. because the part of inserting has been arranged, the production cycle that has shortened mould effectively can be changed after the damage at any time 2. because the part of inserting has been arranged, and has reduced economic cost effectively.

Four, description of drawings:

Fig. 1 is a normal cross-section structural representation of the present utility model;

Fig. 2 be among Fig. 1 A-A to the sectional structure schematic diagram;

Fig. 3 be among Fig. 1 B-B to the sectional structure schematic diagram;

Fig. 4 is the insert structure schematic diagram identical with the banding cross sectional shape;

Fig. 5 is the insert structure schematic diagram identical with going up shape of cross section admittedly;

Fig. 6 is and the flat identical insert structure schematic diagram of sliding cross sectional shape of;

Fig. 7 is the insert structure schematic diagram identical with the downslide cross sectional shape;

Fig. 8 is the insert structure schematic diagram identical with the closing in cross sectional shape;

Five, the specific embodiment:

Embodiment 1: referring to Fig. 1, Fig. 2, Fig. 3, the utility model is made of patrix 1,

counterdie

2 and 3 three parts of inserting.Patrix is made of deflector 4 and seam chamber 5, have four tap holes 6 as shown in Figure 2 on the described deflector, the tap hole bottom is connected to the seam chamber, counterdie closely is embedded in inserting, inserting is provided with water conservancy diversion hole 7, and water conservancy diversion is processed with the shaped hole 8 identical with the aluminium alloy extrusions cross sectional shape on the hole, and liquid aluminium enters the seam chamber by tap hole, enter the water conservancy diversion hole again, after shaped hole enters work zone 9.Therefore, can require to select the difform mould of inserting for use according to difference, thereby make the section bar of different cross section shape.Described upper and lower mould is fixed into one by screw 10; Described insert and counterdie is fixed into one by screw 11.

Embodiment 2: lifted among prepared aluminium alloy extrusions cross sectional shape and Fig. 4-Fig. 8 in the present embodiment insert in shaped hole identical.

Claims

1. a mould multicore extrusion die comprises upper die and lower die and inserts, and it is characterized in that: patrix is made of deflector, seam chamber; Have several tap holes on the described deflector, the seam chamber is arranged on the bottom of tap hole; Described counterdie closely is embedded in inserting, and inserts to be provided with the water conservancy diversion hole, and the water conservancy diversion hole communicates with the seam chamber; Water conservancy diversion is processed with the shaped hole identical with the aluminium alloy extrusions cross sectional shape on the hole, and the shaped hole bottom is connected with the work zone.

2. a mould multicore extrusion die according to claim 1 is characterized in that: 2-10 tap hole can be set on the described deflector.

3. a mould multicore extrusion die according to claim 1 is characterized in that: the shape of the described shaped hole of going up processing inserted can be respectively with banding, that horizontal, flat any section bar cross sectional shape sliding, in gliding, closing up identical admittedly.
