According to the diamond compact mold, the metal shielding layers are arranged outside the dolomite ring, pyrophyllite is effectively prevented from permeating into the synthetic cavity at high temperature, and the qualified rate of the products is improved.
Description
Technical field
The utility model belongs to mould applications, relates in particular to a kind of wire-drawing die of producing polycrystalline diamond.
Background technology
The Diamond dies of auto parts and components processing use generally adopts polycrystalline diamond wire drawing die, Glomerocryst adamas legging mould is in sintering process, the mould using is under high-temperature high-pressure state, so the design of mould must meet following principle: pressure transmission characteristic is good, heat-insulating property is strong, good airproof performance.In order effectively to utilize HTHP space, improve performance and the yield rate of composite sheet, must overcome existing mold difficult point.These defects are: axial temperature difference is large, and synthetic rod two ends and middle axial temperature difference are too large, synthesis technique cannot be adjusted to make them can be well sintered combined, serious waste limited synthetic cavity.And the high-temperature phase-change of pyrophyllite is easily penetrated in synthetic cavity, synthetic cavity is polluted, cause product qualified rate low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of auto parts and components processing diamond compact mould is provided, can make the hollow synthetic rod two ends and the middle axial temperature difference that by pressure transfer, zone of heating and white clouds stone ring, are formed reduce, composite polycrystal-diamond two ends are heated evenly, and can effectively prevent the infiltration of pyrophyllite, improved the qualification rate of finished product.
For achieving the above object, the utility model is by the following technical solutions:
A kind of auto parts and components processing diamond compact mould, comprise overcoat and synthetic cavity, synthetic cavity is arranged in overcoat, between synthetic cavity and overcoat, be provided with pyrophillite pressure transfer, upper and lower side at synthetic cavity is respectively arranged with conductive steel cap, between conductive steel cap and synthetic cavity, be also provided with conducting strip, between the synthetic cavity between upper and lower conducting strip and pyrophillite layer, be also provided with hollow synthetic rod, it is characterized in that: hollow synthetic rod has interior pressure transfer from inside to outside successively, zone of heating, outer pressure transfer, impervious barrier and white clouds stone ring form, in described, outer pressure transfer is all salt layers, between conducting strip and steel cap, be also provided with additional backing, in steel cap, be provided with and add core, two metal screen layers are at least set between white clouds stone ring and pyrophyllite layer, between adjacent two metal screen layers, mutually overlap.
Above-mentioned auto parts and components processing diamond compact mould, described screen layer is three layers, respectively internal shield, middle screen layer and external shielding layer, internal shield and external shielding layer are arranged on the lower shoe of overcoat, middle screen layer is arranged on the upper plate of overcoat, and middle screen layer is plugged between interior external shielding layer.
Above-mentioned auto parts and components processing diamond compact mould, described in to add core be that organic resistance powder is compressed on the powder pressure forming in steel cap and adds core.
Diamond compact mould is used in above-mentioned auto parts and components processing, between conducting strip and the end of hollow synthetic rod, is also provided with interior heating plate.
Above-mentioned auto parts and components processing diamond compact mould, described inside and outside heating plate is all the heating plates that formed by heat conduction powder compaction.
It is that thickness is the magnesium oxide layer of 1mm that diamond compact mould, described impervious barrier are used in above-mentioned auto parts and components processing.
Adopt technique scheme, the utility model has following advantage: owing to being provided with additional backing between conducting strip and steel cap, between hollow synthetic rod and conducting strip, be also provided with interior heating plate, thereby make hollow synthetic rod two ends and jackshaft to having a narrow range of temperature, synthetic cavity is under the effect of conductive layer and inside and outside heating plate like this, all directions are heated evenly, and have improved yield rate.On the other hand, owing to being also provided with impervious barrier in zone of heating outside, in white clouds stone ring outside, be also arranged with at least double layer of metal screen layer, at high temperature can effectively prevent that pyrophyllite is penetrated in synthetic cavity, has improved the qualification rate of product.
