Abstract
The utility model relates to a prevent vacuum hot -pressing sintering mould of carburization, including graphite external mold, metal inner skleeve, layering metal sheet, metal inner skleeve suit is in the graphite external mold to laminate with the graphite external mold, lay the layering metal sheet in the metal inner skleeve, during the use, metal product and the successive layer setting in turn of layering metal sheet carry out the punching press by the drift. The utility model discloses be suitable for vacuum hotpressing method production metal class product, the graphite external mold plays the effect of hot pressing process holding capacity, and the metal inner skleeve adopts the concatenation of multistage formula, is favorable to carrying on in the graphite external mold automatic fine tuning behind the atress, can not take place the reaction with metal product simultaneously. The terminal surface of the section of thick bamboo wall of metal inner skleeve sets up 2~4 chamfer, does benefit to the concatenation of equipment of a whole set of mould and metal inner skleeve. The utility model discloses during implementation, a mould can go out the polylith product, and the middle layering metal sheet that adopts separates metal product in the metal inner skleeve layer upon layer, and the yields is guaranteed simultaneously to the increase of production.
Description
Technical field
The utility model relates to a kind of mould for the forging of large-sized forging hydraulic machinery, more particularly, relates to a kind of vacuum heating-press sintering mould preventing carburizing.
Background technology
At present, the material for vacuum hotpressing mould is generally only graphite type material, and when vacuum hot-pressing produces metal group material, Chang Huiyu conventional graphite mold wall contacts, and carburizing occurs, causes finished product rate low, and even the situation of non-defective unit does not occur.
And there is the problem of dismounting inconvenience, poor durability in the mould for vacuum hot-pressing of prior art.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide that a kind of yield rate is high, easy disassembly, good endurance the vacuum heating-press sintering mould preventing carburizing.
The technical solution of the utility model is as follows:
Prevent a vacuum heating-press sintering mould for carburizing, comprise graphite external mold, inner metal sleeve cylinder, layered metal plate, inner metal sleeve jacket casing is contained in graphite external mold, and fits with graphite external mold; Layered metal plate is laid in inner metal sleeve cylinder; During use, metallic article and layered metal plate are alternately successively arranged, and carry out punching press by drift.
As preferably, inner metal sleeve cylinder comprises at least three sections of barrels, and barrel surrounds inner metal sleeve cylinder.
As preferably, the end face of barrel arranges the chamfering of 2 ° ~ 4 °.
As preferably, during use, metallic article and layered metal plate are alternately successively arranged, and most top layer is layered metal plate.
As preferably, the shape of layered metal plate and the shape of metallic article are coincide.
The beneficial effects of the utility model are as follows:
The utility model is suitable for vacuum hot-pressing production metal species product, graphite external mold plays the effect of hot pressing holding capacity, inner metal sleeve cylinder adopts multisection type splicing, be conducive to stressed in graphite external mold after carry out automatic fine tuning, can not react with metallic article simultaneously.The end face of the barrel of inner metal sleeve cylinder arranges the chamfering of 2 ° ~ 4 °, is beneficial to the splicing of whole set of die assembling and inner metal sleeve cylinder.
When the utility model is implemented, a mould can go out polylith product, and metallic article, in inner metal sleeve cylinder, separates, improves output, ensure yields simultaneously by the middle layered metal plate that adopts layer by layer.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The utility model provides a kind of vacuum heating-press sintering mould preventing carburizing, and as shown in Figures 1 to 5, comprise graphite external mold 11, inner metal sleeve cylinder 12, layered metal plate 13, inner metal sleeve cylinder 12 is sleeved in graphite external mold 11, and fits with graphite external mold 11; Layered metal plate 13 is laid in inner metal sleeve cylinder 12.During use, metallic article 15 and layered metal plate 13 are alternately successively arranged, and carry out punching press by drift 14.Preferably, most top layer is layered metal plate 13, ensures the quality of most top-level metallic goods 15.The utility model is applicable to vacuum hot-pressing production metal species product, and graphite external mold 11 plays the effect of hot pressing holding capacity.And adopt layered metal plate 13 to separate layer by layer between polylith product, a mould can go out polylith product, improve output.
Inner metal sleeve cylinder 12 comprises at least three sections of barrels 121, and barrel 121 surrounds inner metal sleeve cylinder 12.Multisection type splicing be conducive to mould inside stressed after finely tune voluntarily, can not react with metallic article 15 simultaneously.The end face of barrel 121 arranges the chamfering 122 of 2 ° ~ 4 °, is conducive to the splicing of whole set of die assembling and inner metal sleeve cylinder 12.
In order to make layered metal plate 13 support metallic article 15 better, the shape of layered metal plate 13 and the shape of metallic article 15 are coincide.
In the present embodiment, graphite external mold 11 adopts density > 1.87g/cm
3the isostatic pressing formed graphite overall processing of d is shaped.Inner metal sleeve cylinder 12 adopts density > 10.00g/cm
3molybdenum board material roll bending makes molybdenum sleeve 12, and then use laser cutting machine to be all divided into three sections, wherein there is the chamfering 122 of 2 ° ~ 4 ° every section of junction.Layered metal plate 13 adopts density > 10.00g/cm
3molybdenum plate make molybdenum dividing plate, and use laser cutting machine to be cut to the size of metallic article 15.Inner metal sleeve cylinder 12, layered metal plate 13 also can adopt tungsten.
Above-described embodiment is only used to the utility model is described, and is not used as restriction of the present utility model.As long as according to technical spirit of the present utility model, change above-described embodiment, modification etc. all will be dropped in the scope of claim of the present utility model.
