Abstract

The utility model discloses a hot extrusion combined mold, relating to the technical field of metal extrusion molding tools. The hot extrusion combined mold disclosed by the utility model comprises an outer mold and an inner mold which are arranged in a split manner, wherein the outer mold and the inner mold are of annular structures, and the inner wall of the outer mold is in conical surface fit with the outer wall of the inner mold. The hot extrusion combined mold disclosed by the utility model has the advantages of light weight and convenience in assembly, disassembly and usage, and can effectively prolong the service life of the mold, improve the utilization rate of the mold, reduce the waste of materials and reduce the production cost.

Description

Hot-extrusion composite mould
Technical field
The utility model relates to extruding metal shaping jig technical field.
Background technology
At present, the mould adopted in extruding metal processing is all unitary mould, and in the moulding process of the high-end tubing such as nickel-base alloy, mostly adopt mould to carry out hot extrusion, in hot extrusion process, extrusion die need to bear high temperature, high pressure, strong water-cooled and the swiftly flowing severe operating environment of deformable metal, the defects such as the inner surface of extrusion die often can cave in, crackle, distortion, have a strong impact on the dimensional accuracy of product, and a kind of corresponding a series of products that match with the extruding die holder of die holder that push, and each series all has 5-6 kind product specification, but each part product has uniqueness, therefore the design of the monolithic extruded mould of each part is all one to one with respect to the extruding die holder, the extrusion die corresponding to extruding die holder of each specification is unique, therefore, extruding die holder with respect to a kind of specification, to the extrusion die that the 5-6 kind is different should be arranged, due to the distortion due to mould inner surface in hot extrusion process of monolithic extruded mould, can have a strong impact on the service life of mould, therefore need integral replacing, cause the waste of material, also strengthened production cost, monolithic extruded mould is heavier, and mounting or dismounting are inconvenient.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of hot-extrusion composite mould, lightweight, mounting or dismounting are easy to use, can effectively improve service life and the utilization rate of mould, reduce the waste of material, reduces production costs.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of hot-extrusion composite mould, comprise external mold and internal mold that split arranges, described external mold and internal mold are circulus, are cone match between the inwall of described external mold and the outer wall of internal mold.
Preferably, the outer wall of described external mold and the outer wall of internal mold are the conical surface, all with the conical surface of the die holder inwall matched, have identical tapering.
Preferably, the endoporus of described internal mold is forming hole, and its two ends all arrange chamfering.
The beneficial effect that adopts technique scheme to produce is: the utility model is divided into internal mold and external mold, can only change internal mold when changing, and has alleviated the weight of mould, has saved material; The mating surface of internal mold and external mold is the conical surface, and internal mold is not only played to the guide-localization effect, and the internal mold outer wall has identical tapering with serial die holder endoporus, can match with corresponding die holder, can make internal mold become separately a kind of extrusion die; External mold and internal mold can be independent use, become a kind of extrusion die, adapt to the needs of different die holders series and different train, improved the utilization rate of mould, reduced cost; At the internal mold two ends, chamfering is set, can facilitates the taking-up of product.The utility model is lightweight, mounting or dismounting are easy to use, can effectively improve service life and the utilization rate of mould, reduces the waste of material, has reduced production cost.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1-external mold; The 2-internal mold.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, hot-extrusion composite mould, comprise external mold 1 and internal mold 2 that split arranges, and described external mold 1 and internal mold 2 are circulus, are cone match between the outer wall of the inwall of described external mold 1 and internal mold 2.
Preferably, the outer wall of the outer wall of described external mold 1 and internal mold 2 is the conical surface, has identical tapering with the conical surface of the die holder inwall matched; The endoporus of described internal mold 2 is forming hole, and its two ends all arrange chamfering.
The utility model is split as external mold 1 and 2 two moulds of internal mold to monolithic extruded mould, the outer wall of the outer wall of described external mold 1 and inwall, internal mold 2 is taper seat, and with the inwall of die holder, have identical tapering, external mold 1, internal mold 2 all can be used in combination with serial die holder like this.Due to the corresponding a series of product of a kind of extruding die holder, therefore for a kind of die holder, external mold 1 uses separately corresponding a kind of product; External mold 1 and internal mold 2 are used in conjunction with, corresponding a series of product; Internal mold 2 coordinates with corresponding die holder, uses separately corresponding a kind of product, and the utility model just can corresponding a series of product like this.The two ends of internal mold 2 arrange chamfering, facilitate the taking-up of product.
When the utility model external mold 1 and internal mold 2 are used in conjunction with, the distortion on internal mold 2 surfaces, can only change internal mold 2 gets final product, not only alleviated the weight of mould, mounting or dismounting are convenient, more saved material, greatly reduced production cost, internal mold 2 and external mold 1 can use as mould separately again simultaneously, have greatly improved the utilization rate of mould.
External mold 1 first is installed during use, and external mold 1 closely cooperates with die holder, rear installation internal mold 2, and external mold 1 and internal mold 2 utilize retainer plate to position, and finally utilize mould supporting handle external mold 1 and internal mold 2 to compress.
The utility model mounting or dismounting are easy to use, lightweight, can effectively improve service life and the utilization rate of mould, reduce the waste of material, reduced production cost.
