Description
Technical field:
The invention belongs to the mould class, particularly relate to a kind of frequency hopping radio station aluminum alloy shell extrusion molding dies of an extrusion modling.
Background technology:
As everyone knows, be used to load the FM radio station aluminum alloy casing of communication line plate on the transmiter, because its section configuration complexity, inner passage size and gusset gauge do not wait, gusset thickness 0.8-1.5mm only especially, and asymmetric, therefore the traditional precision casting process of many employings, but it need overlap sand mo(u)ld with three molds preparation one, and the service life of a cover sand mo(u)ld is short, and it can only cast a product, so productivity ratio is low, in addition, the defective that casting technique itself is intrinsic has a strong impact on the serviceability of product, simultaneously, the product of at every turn casting, its size can not be in full accord, so interchangeability is poor.
Summary of the invention:
Main purpose of the present invention is to overcome above deficiency and provides a kind of product precision height, the frequency hopping radio station aluminum alloy shell extrusion molding dies of the multichannel enclosed construction that interchangeability is good.
The technical solution adopted for the present invention to solve the technical problems is: it is by die sleeve, patrix, core rod, middle mould and support mould are formed, it is characterized in that: patrix 1 and core rod 2 are one, patrix 1 center is near locating to have external shunt hole 3 around the core rod, the center at patrix 1 back side and shielding gusset 5 corresponding sections on the core rod 2 have rectangular interior tap hole 4, external shunt hole 3 is continuous circular shape band 6 and has the gradient with core rod 2 junctions, aim at shielding gusset 5 places on this surface, endless belt and have guiding gutter 7, core rod 2 is divided into 11 shielding gussets 5 and 12 guide rail dovetail grooves 8 that passage is interior of 12 passages, center positions have seam chamber 10 in the middle mould 9, its inner lane is fixed with and hinders wall 11, flowing velocity and inside and outside tap hole 4 for balance shield gusset 5 places, the flow velocity unanimity of 3 place's metals, as shown in the figure: hinder the height difference of wall 11, side is work zone 12 within it.
The present invention can also adopt following technical measures: described external shunt hole 3 is the gradient and has drainage circular arc 13 in the middle of the adjacent external shunt hole 3 for wing.
Advantage and good effect that the present invention has are: simple in structure, realized mass and serialization production, and product precision height, fitted position has interchangeability, has improved lumber recovery, prevents public hazards, has improved environment, has reduced labour intensity, and cost is low.

The specific embodiment:
For further understanding summary of the invention characteristics of the present invention and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1-Fig. 7.
As shown in Figure 1: the present invention is 12 corridor diversion combination dies, aluminium alloy bars base after the heating produces product is finished in plastic flow again after the seam of seam chamber pressure moulding by tap hole, this mould is by patrix 1, core rod 2, middle mould 9 constitutes, patrix 1 and core rod 2 are one, patrix 1 center is near locating to have wing external shunt hole 3 around the core rod 2, be the gradient and have drainage circular arc 13 in the middle of per two adjacent holes, flow direction during with the guide wire flow, more helping metal fully fills, as Fig. 2, it is shown in Figure 3: because core rod 2 is divided into the guide rail dovetail groove 8 on 11 of 12 passages shielding gussets 5 and 12 passages, shielding gusset 5 is 0.8-1.5mm, 11 shielding gusset 5 thickness size differences because of 12 passages, asymmetric again, dovetail groove 8 thickness sizes in 12 passages are also different, so, the center at patrix 1 back side and shielding gusset 5 corresponding sections on the core rod 2 have rectangular interior tap hole 4, external shunt hole 3 is the continuous circular shape band 6 that has the gradient with core rod 2 junctions, aim at shielding gusset 5 places on the surface of this endless belt 6 and have guiding gutter 7, interior tap hole 4 and guiding gutter 7 all can guarantee to shield the feed of gusset 5 and the dimensional accuracy after the moulding, and can avoid this place's metal fracture fully, as Fig. 4-shown in Figure 6: center positions have seam chamber 10 in the middle mould 9, its inner lane is fixed with and hinders wall 11, hinder the height difference of wall 11, to guarantee the do not exist together uniformity of metal flow speed of product thickness, hindering wall 11 inboard exits is work zone 12, and the product that comes out of extruding is 12 passage enclosed construction extrudates 17 as shown in Figure 7 from here.
In use, with the die sleeve in the mold assemblies 14, go up film 1, middle mould 9 and a hold mode 15 and pack into successively and be fixed in the extruder, last film 1 and 16 pairs of mutatis mutandis screws of middle mould 9 usefulness alignment pins are fixed, rods and bars of aluminium alloy after the heating is pressed into from die sleeve 14 rear arrows, is squeezed into the section bar 17 that dimensional accuracy meets the requirements on the process behind film 1 and the middle mould 9.Because this mould uses on 5500 tons of extruders, mould should have the pressure that very high intensity could be carried 260N/mm, could under 450 ℃ of uses of high temperature, satisfy higher rigidity requirement, particularly the alternate stress when continuously extruded is to the alternate load of mould generation, in addition, inside and outside frictional force in the time of also will overcoming rods and bars of aluminium alloy and in recipient, move, so require mould should have higher red hardness, the present invention has selected Austrian 8402 trade mark import mould steel for use, material is heat-treated, make the structure refinement of mould steel, thoroughly eliminate the structural stress and the temperature stress of mould, the service life of improving mould by tempering repeatedly.
Advantage of the present invention is: simple in structure, realized mass and serialization production, and the Product Precision height, Fitted position has interchangeability, has improved lumber recovery, prevents public hazards, has improved environment, has reduced work Intensity, cost is low.
