Description

A kind of aluminium section bar multi-hole extrusion die

Technical field

Technical field of mold is the utility model is related to, more specifically, more particularly to a kind of aluminium section bar multi-hole extrusion die.

Background technology

The design of mould occupies extremely important status with manufacture in Extrusion Process of Aluminum Alloy Profile industry, the production to aluminium profile product Amount, quality, production efficiency and economic benefit of enterprise etc. suffer from important effect.All the time, square flat tube aluminium section bar Production all carried out on single hole mould, i.e., can only once extrude production a piece product forms, this mode of production efficiency It is low, production capacity is low, in actual production, for ensure yield, mould dosage need to be increased, shared board number also accordingly increases, energy consumption Greatly, production cost is high.

Utility model content

The purpose of this utility model is to be directed to above-mentioned the deficiencies in the prior art, there is provided a kind of aluminium section bar porous extrusion die Tool, more product forms of production can be once extruded, improve production efficiency, reduce energy consumption of unit product and production cost.

To achieve the above object, the technical solution adopted in the utility model is：A kind of aluminium section bar multi-hole extrusion die, including The upper die and lower die of interconnection, 12 tap holes are provided with altogether on the feed end of the upper mould, 12 tap holes are pressed Four, mould center hole, the mode in peripheral eight holes of mould arrange, wherein, four tap holes at the mould center are public charging hole, It is made up of symmetrically arranged No. I tap hole and No. II tap hole two-by-two, eight tap holes of the mould periphery are independent charging hole, It is made up of four symmetrically arranged No. III tap holes and four symmetrically arranged No. IV tap holes；I~No. IV tap hole Section configuration is different, and the upper mould sets four shunting bridges and one between every four different I~No. IV tap hole Center die bridge, each center die pars basilaris pontis are equipped with a core rod；The feed end of the lower mould is provided with by interlaced horizontal stroke Four main bonding containers being separated to partition wall and withe, each main weldering close interior and are equipped with a two level bonding container, The empty knife that each two level bonding container bottom is equipped with a nib corresponding with core rod and connected with nib.

Produced using the utility model porous mold, once charging can extrude more aluminium profile products simultaneously, greatly It is big to improve extruding production efficiency and mould utilization factor, the extruding force of extrusion process is reduced, while also more fully make use of The extrusion capability of extrusion equipment, reduce the energy consumption of unit product.

Embodiment

The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but does not form to this reality With new any restrictions.

As depicted in figs. 1 and 2, a kind of aluminium section bar multi-hole extrusion die provided by the utility model, including interconnection Upper mould 1 and lower mould 2,12 tap holes 11 are provided with the feed end of the upper mould 1 altogether, and 12 tap holes 11 are pressed in mould Four holes of the heart, the mode in peripheral eight holes of mould arrange, wherein, four tap holes at the mould center are public charging hole, by two Two symmetrically arranged No. I tap holes 111 and No. II tap hole 112 form, and described two No. I tap holes 111 are located at the horizontal stroke of upper mould 1 To center line（That is the X-axis line in Fig. 2）The upper, longitudinal centre line on upper mould 1（That is the Y-axis line in Fig. 2）It is symmetrical arranged, it is described Two No. II tap holes 112 are symmetrical arranged on the longitudinal centre line of upper mould 1, on the cross central line of upper mould 1；The mould Eight tap holes of periphery are independent charging hole, by four symmetrically arranged No. III tap holes 113 and four symmetrically arranged IV Number tap hole 114 forms, the longitudinal and transverse center of described four No. III tap holes 113 and four No. IV tap holes 114 on upper mould 1 Line is symmetrical arranged.

In the utility model, the section configuration of I~No. IV tap hole 111~114 is different, specifically, No. I Tap hole 111 is similar to No. II section configuration of tap hole 112, is similar to rhombus, but compared with No. I shunting of No. II tap hole 112 The width of hole 111 is smaller, length is longer, and No. III section configuration of tap hole 113 is similar to triangle, No. IV section shape of tap hole 114 Shape is similar to sector.In addition, the upper mould 1 sets four points between every four different I~No. IV tap hole 111~114 Stream bridge 12 and a center die bridge 13, each bottom of center die bridge 13 are equipped with a core rod 14.
