Abstract
A kind of porous aluminium section die of the utility model, comprising punch-pin and matching cavity plate, the discharge pedestal of protrusion is set, discharge pedestal sets some muscle discharge openings corresponding with muscle among punch-pin, muscle discharge opening is two or more, and each muscle discharge opening corresponds to an inlet.The beneficial effects of the utility model are.Adopt the structure, each corresponding muscle discharge opening of inlet so that feed is more uniformly distributed, and, for different demands, each inlet can be separately provided, for example, the size in hole, the gradient at hole edge, so as to control the flow velocity of extruding, so that extrusion is better, the muscle smoothness and rigidity of aluminium section bar are more preferable, aluminium section bar high yield rate.
Description
Technical field
A kind of section bar mold is the utility model is related to, more particularly to a kind of porous aluminium section die.
Background technology
Aluminium section die is divided into punch-pin and cavity plate（Also known as male model, master mold）, after punch-pin and cavity plate coordinate, squeezed by extruder
Jewelling rod obtains the aluminium section bar of Structure of need by mould.Punch-pin is provided with some feed orifices, cavity plate shape and shape needed for section bar
Shape matches, and mould is used by punch-pin and die set, and aluminium bar is squeezed into mould by extruder from feed orifice, and by cavity plate
Section bar needed for the section bar of discharging opening basis.
It is as shown in figure 1, be a kind of aluminium section bar of specific structure, the characteristics of this aluminium section bar, middle part has more
Bar muscle A, the width of muscle is smaller, and the both sides of muscle are hole B.
This section bar difficulty in extruding is larger, and cavity plate matches with section bar profile.As shown in Fig. 2 set among punch-pin
The discharge pedestal 1 of protrusion, discharge pedestal 1 set some muscle discharge openings 2 corresponding with muscle, and each muscle discharge opening 2 extrudes a muscle.It is existing
In some punch-pin, muscle discharge opening 2 connects a big inlet（Do not mark overleaf）, discharged by this big inlet for muscle
Hole 2 is fed.
Although such a structure can complete the extrusion forming of such a section bar with muscle, the big mouth structure that is fed causes
The discharging uniformity of each muscle discharge opening is not easy to ensure, the muscle squeezed out is all less desirable in smoothness, rigidity etc. so that type
Material yield rate is not high, the space that this technology is still improved.
Utility model content
The technical problem that the utility model solves is to provide a kind of porous aluminium section die, dedicated for production band muscle
Aluminium section bar so that the aluminium section bar high yield rate squeezed out, the muscle smoothness of aluminium section bar and rigidity are more preferable.
Technological means is as described below used by the utility model.A kind of porous aluminium section die, comprising punch-pin and therewith
The cavity plate of matching, punch-pin centre set the discharge pedestal of protrusion, and discharge pedestal sets some muscle discharge openings corresponding with muscle, muscle discharging
Hole is two or more, the corresponding inlet of each muscle discharge opening.
The beneficial effects of the utility model are.Adopt the structure, the corresponding muscle discharge opening of each inlet so that supply
Material is more uniformly distributed, also, is directed to different demands, and each inlet can be separately provided, such as the size in hole, hole edge
The gradient, so as to control the flow velocity of extruding so that extrusion is better, and the muscle smoothness of aluminium section bar and rigidity are more preferable, aluminium section bar
High yield rate.
Brief description of the drawings
Fig. 1 is a kind of aluminium section bar with muscle.
Fig. 2 is existing punch structure stereogram.
Fig. 3 is punch-pin discharge pedestal side structural representation of the present utility model.
Fig. 4 is punch-pin inlet side structural representation of the present utility model.
Embodiment
First, refer to shown in Fig. 3 and Fig. 4, a kind of porous aluminium section die, comprising punch-pin and matching cavity plate,
Cavity plate is identical with prior art, and punch-pin is only provided in figure.The same discharge pedestal 1 that protrusion is set among punch-pin, if discharge pedestal 1 is set
The dry muscle discharge opening 2 corresponding with muscle, it focuses on, and muscle discharge opening 2 is two or more, and each muscle discharge opening 2 corresponds to one
Individual inlet 3.
Adopting the structure, the corresponding muscle discharge opening of each inlet so that feed is more uniformly distributed, also, for not
Same demand, each inlet can be separately provided, for example, the size in hole, the gradient at hole edge, so as to control extruding
Flow velocity so that extrusion is better, and the muscle smoothness and rigidity of aluminium section bar are more preferable, aluminium section bar high yield rate.
Claims (1)
1. a kind of porous aluminium section die, comprising punch-pin and matching cavity plate, the discharge pedestal of protrusion is set among punch-pin, gone out
Expect that platform sets some muscle discharge openings corresponding with muscle, it is characterised in that muscle discharge opening is two or more, each muscle discharge opening
A corresponding inlet.
