Description

Big cross section multi-mould core hot extrusion die

Technical field

The utility model relates to a kind of hot-extrusion mold, and especially a kind of big cross section multi-mould core hot extrusion die, belongs to industrial materials technical field of mold.

Background technology

Because aluminium has good extrusion molding, and there is a meter heavy and light, the advantages such as intensity is good, so aluminium is widely used in industry, the technical fields such as decoration.But in big cross section multimode core pattern material because aluminium bar is little, section material section again large, need large expansion, have multiple core rod, considerably increase the shaping difficulty of section bar like this.Bring very large difficulty with the production of section bar therefore to manufacturing and designing of mould! One: section material section is large, during tap hole many extruding, frictional force is large, crowded motionlessly causes vexed car normally to produce; The easy beat of core rod, makes the profile wall thickness ununiformity extruded.Its two: cantilever beat, directly cause mould to scrap.This just makes the cost producing this big cross section multimode core pattern material improve widely, reduce costs, and only starts with from optimization Design of Dies aspect.

Summary of the invention

The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of big cross section multi-mould core hot extrusion die, the aluminium section bar of energy High-efficient Production big cross section multimode core.

According to the technical scheme that the utility model provides, described big cross section multi-mould core hot extrusion die, comprise the upper die and lower die set gradually from A-P, it is characterized in that: described counterdie sets gradually one-level bonding container, secondary bonding container, die cavity and discharge opening from feed end to discharge end; The discharge end of described patrix is provided with multiple core rod; Described patrix is provided with multiple tap hole, and the discharge end of each tap hole is separated into 4 tap holes outlets, forms shunting bridge between the feed end of described tap hole, shunting bridge respectively with core rod one_to_one corresponding, shunting bridge shelters from core rod; 4 tap hole outlets lay respectively at the both sides of core rod.

Further, described secondary bonding container is consistent with the outline of section bar.

Further, the import exported relative to tap hole of described tap hole is offset laterally by the center of patrix and forms outer reaming.

Further, described upper die and lower die are by screw and pin close-fitting.

Big cross section multi-mould core hot extrusion die described in the utility model, by blocking of shunting bridge, and the symmetrical balance design that of tap hole enters to have more, and the stabilization of counterdie secondary profiling bonding container, controls the beat of core rod, problem that section big mould core is many well.Therefore thoroughly solve bad, the inclined wall of this type of mould molding and yield poorly, the problems such as production efficiency is not high.

Detailed description of the invention

Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.

As shown in Fig. 1 ~ Fig. 6: as described in big cross section multi-mould core hot extrusion die comprise patrix 1, core rod 1-1, tap hole 1-2, tap hole outlet 1-3, outer reaming 1-4, shunting bridge 1-5, counterdie 2, one-level bonding container 2-1, secondary bonding container 2-2, die cavity 2-3, discharge opening 2-4 etc.

As shown in Figure 1 and Figure 2, the utility model comprises the patrix 1 and counterdie 2 that set gradually from A-P, and patrix 1 and counterdie 2 are by two screws and two pin close-fittings.

As shown in Figure 5, Figure 6, described counterdie 2 sets gradually one-level bonding container 2-1, secondary bonding container 2-2, die cavity 2-3 and discharge opening 2-4 from feed end to discharge end, secondary bonding container 2-2 is consistent with the outline of section bar, ensure that the stable of aluminum flux and balance, mould product moulding when extruding is stablized.

As shown in Figure 3, Figure 4, the discharge end of described patrix 1 is provided with multiple core rod 1-1; Described patrix 1 is provided with multiple tap hole 1-2, and the discharge end of each tap hole 1-2 is separated into 4 tap hole outlet 1-3, and tap hole described in the utility model adopts one to enter to have more, and can reduce friction; Described tap hole outlet 1-3 to be offset laterally by the center of patrix 1 relative to the import of tap hole 1-2 and forms outer reaming 1-4.Form shunting bridge 1-5 between the feed end of described tap hole 1-2, shunting bridge 1-5 respectively with core rod 1-1 one_to_one corresponding, thus shunting bridge 1-5 directly shelters from core rod 1-1, effectively avoids aluminium stream to the direct impulsive force of core rod 1-1; 4 tap hole outlet 1-3 lay respectively at the both sides of core rod 1-1, thus the symmetrical flow equilibrium of core rod 1-1 both sides tap hole, fundamentally ensure that the stability of core rod, thoroughly solve a difficult problem for core rod beat and arm thickness ununiformity.

The utility model is in extrusion process, and after the shunting of shunting bridge, aluminium stream is avoided core rod and to be gone directly one-level bonding container, ensure that the stability of core rod.The most important thing is, tap hole of the present utility model have employed a hole and enters the porous design that porous goes out, the layout of tap hole symmetry, make the flow equilibrium on core rod both sides, the pressure be subject to is equal, controls the beat of core rod part well, alleviates again the problem that porous entrance pressure power is large; Can say, very ideally solve the problem that mould core part beat pressure is large.And aluminium flows to the seam into counterdie secondary bonding container, enable mould stable squeeze out qualified section bar, what add every mold greatly goes out material output, ensure that cross-section size of section, improve the production efficiency of section bar, reduce the die cost of producing similar section bar and consuming.
