Description

A kind of aluminium alloy hot-extrusion die

Technical field

It the utility model is related to aluminium alloy extrusion mould field, more particularly to a kind of aluminium alloy hot-extrusion die.

Background technology

It is current known, since aluminium alloy hot-extrusion die needs to excavate heat on the mold base come is bought back when production The trough of belt and work band of extruding；But due to when trough of belt and work band is excavated, easily occurring excavating error, causing monoblock Hot-extrusion mold is unqualified, then it is unqualified to may result in the product squeezed out, so this aluminium alloy hot-extrusion die is Can be adopted；But comparatively, it is higher to manufacture the mold base cost price of mould, so will result in production cost increasing Add；Need, by the aluminium alloy extruded into shaping of high temperature, to be molded by work band, touching height as well as hot-extrusion mold After the aluminium alloy of temperature, and power is squeezed at the same time, so trough of belt and work band are easily deformed, cause mould to make again With, it is necessary to more mold exchange；And each replace all is to need to remove on whole one piece of mould, thus need the mold materials that consume compared with It is more, add the cost of production.

Therefore, the prior art has yet to be improved and developed.

Utility model content

The utility model aim is to provide a kind of aluminium alloy hot-extrusion die, it is intended to solves existing aluminum alloy heat extrusion die Tool bears extruding force due to contacting high temperature when work, is easily deformed, to ensure the qualification rate of product, it is necessary to often more Whole aluminium alloy hot-extrusion die is changed, causes that the production cost increases；And somewhat there is mistake in manufacture aluminium alloy hot-extrusion die It will result in whole block processing mold base damage, it is difficult to the technical problem reused.

The technical solution of the utility model is as follows：A kind of aluminium alloy hot-extrusion die, it includes die sleeve body and digs mould mould Body；The die cavity being detachably connected corresponding with digging mould die body is provided with the die sleeve body, mould die body is dug and is nested in die cavity；Institute State to dig on mould die body and be carved with the trough of belt of work band, and the work band for hot extrusion is provided with trough of belt；Dig the nested peace of mould die body It is fixed in die cavity, then by heating by mould volume expansion is dug in die cavity.

The aluminium alloy hot-extrusion die, wherein, the work band is arranged on the bottom of trough of belt.

The aluminium alloy hot-extrusion die, wherein, the outer circumference of the die sleeve body is additionally provided with for installation Screens platform.

The aluminium alloy hot-extrusion die, wherein, it is described to dig the digging mould die body that mould die body is stainless steel making.

The aluminium alloy hot-extrusion die, wherein, the digging mould die body is cylinder either round estrade or four side columns Body or pentagon cylinder.

The beneficial effects of the utility model：The utility model is by being divided into die sleeve body by hot-extrusion mold and digging mould die body Two parts, and die cavity is set on die sleeve body so that digging mould die body can be embedded in die cavity；So in engraved die work band When, it is only necessary to dig mould die body on be carved with can, be then fitted on die sleeve body；So while engraving is unqualified Or service failure, and need replacing dig mould die body this part can, it is not necessary to replace whole extrusion die, so Comparatively, original mold manufacturing material of more than half is saved.

Brief description of the drawings

Fig. 1 is a kind of schematic diagram of the utility model.

Fig. 2 is the structure diagram of die sleeve body in the utility model.

Fig. 3 is the structure diagram that mould die body is dug in the utility model.

Embodiment

To make the purpose of this utility model, technical solution and advantage clearer, clear and definite, develop simultaneously implementation referring to the drawings The utility model is further described in example.

As shown in Figs. 1-3, the utility model discloses a kind of aluminium alloy hot-extrusion die, it includes die sleeve body 1 and digs Mould die body 2；The die cavity 11 of nested installation corresponding with digging mould die body 2 is provided with the die sleeve body 1；On the digging mould die body 2 The trough of belt 21 of work band is carved with, and the work band 3 for hot extrusion is provided with trough of belt 21；Dig the nesting of mould die body 2 and be installed on mould In groove 11, then by heating by dig mould volume expansion be fixed in die cavity 11.

With the above structure, hot-extrusion mold is arranged to two parts by the utility model, and a part is die sleeve body, separately One is the digging mould die body for incised work band, is damaged so while digging mould die body when incised work band, Die sleeve body is not interfered with；So even if mould is damaged during production also without whole mould is replaced, only need The intrinsic mould die body that digs of die sleeve is replaced, can be reused；Save the cost for replacing die sleeve body；Simultaneously because Material is somewhat expensive used by die sleeve body, and the utility model is used as using stainless steel and digs mould die body, then cheaper.

Specifically, the work band 3 of the utility model is arranged on the bottom of trough of belt 21；Pass through the work band 3, it is seen that by aluminium Alloy bar, which is squeezed into, to be needed to set shape, and then the purpose produced.

Specifically, the outer circumference of the die sleeve body 1 of the utility model is additionally provided with the screens platform 12 for installation；It is logical Crossing the screens platform 12 can be installed on hot-extrusion mold on die holder.

In specific production, the digging mould die body of the utility model selects stainless steel to be fabricated to stainless steel as making material Dig mould die body；The utility model selects stainless steel to dig mould die body to make, and is because the price of stainless steel is more cheap, carves Digging mould die body be installed in die cavity, then after being heated to 3000 DEG C, the digging mould die body that stainless steel makes can expand, then Tensioner is realized and fixed in die cavity.

In specific production, the digging mould die body 2 of the utility model is cylinder either round estrade or four side column bodies or five Side shape cylinder.

The utility model is by being divided into die sleeve body by hot-extrusion mold and digging mould die body two parts, and on die sleeve body Die cavity is set so that digging mould die body can be embedded in die cavity；So when engraved die works band, it is only necessary to digging mould mould Be carved with body can, be then fitted on die sleeve body；So while carving unqualified or service failure, and need Replace dig mould die body this part can, it is not necessary to whole extrusion die is replaced, so comparatively, saving original half Mold manufacturing material above.

It should be appreciated that the application of the utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come Say, can according to the above description be improved or converted, all these modifications and variations should all belong to the appended power of the utility model The protection domain that profit requires.
