Abstract
The invention discloses the die casting mold technology for making that a kind of three-dimensional piles up shaping gradient-structure, utilize proprietary software to carry out mould modeling and sunykatuib analysis is carried out to press casting procedure, after the three-dimensional gradient structure determining mould and coating material, strict test is carried out to coating sample, finally carries out Making mold and be covered with coating.This die casting mold technology for making adopts three-dimensional special welding forming technique and TD powder Landfill to form resistant to elevated temperatures gradient function structure coating on complex profile compression mod surface, realize less, the processing of chipless, complex-curved three-dimensional special welding be shaped, make to improve 3-5 the service life of compression mod doubly, expand the scope of application of compression mod.This manufacturing technology does not produce the three wastes, on environment without impact.
Description
Technical field
The present invention relates to a kind of manufacturing technology of compression mod.
Background technology
In press casting procedure, can use compression mod, the condition of work of compression mod is extremely severe.During compression mod work and the industry situation Metal Contact of high temperature, not only heated time is long, and heating temperature is higher than hot-forging die, bear very high pressure simultaneously, the high speed being subject to the right effect of heating and cooling repeatedly and metal liquid stream is in addition washed away, under the effect of completely reserved stress, the structure property on mold materials especially top layer progressively changes, and finally causes losing efficacy.In prior art, used pottery as coating, but ceramic coating can cause the getting up early of coating to ftracture with not mating of mould steel matrix in expansion character.The nitridation technique that Japanese uses at first improves the intensity on mould top layer to a certain extent, and make mould top layer in answering pressure state, but nitriding also has its unfavorable, one is the linear expansion coefficient that improve mould top layer, two are reduction of mould just toughness once, the former is by the stress amplitude in aggravation Thermal Cycling, and the latter will speed up the expansion of crackle.
Summary of the invention
The technical problem to be solved in the present invention is to provide the die casting mold technology for making that a kind of three-dimensional piles up shaping gradient-structure.
In order to solve the problems of the technologies described above, the invention provides the die casting mold technology for making that a kind of three-dimensional piles up shaping gradient-structure, adopting following steps to carry out:
(1) professional software, is utilized to carry out modeling to part;

(3), utilize professional software to carry out numerical simulation analysis to die casting process, determine mould inside temperature and thermal stress distribution rule;
(4) the mould inside temperature, obtained according to previous step and the function gradient structure of thermal stress distribution rule determination mould and coating material;
(5), to mould coating sample test, if by test, can use;
(6), mfg. moulding die be covered with coating, come into operation.
As a further improvement on the present invention, the professional software in described step (1) is UG or Pro/e.
As a further improvement on the present invention, the professional software in described step (2) is ProCAST.
As a further improvement on the present invention, the professional software in described step (3) is ProCAST.
As a further improvement on the present invention, in described step (5), XRD x ray diffraction analysis x, microhardness detection, wear-resisting test and thermal shock test are comprised to the test of mould coating sample.
As a further improvement on the present invention, the method for the applying coating of described step (6) can be three-dimensional welding technology, laser melting and coating technique or TD powder landfill implantation technique.
Adopt above-mentioned technical method and step, its beneficial effect is: adopt three-dimensional special welding forming technique and TD powder Landfill to form resistant to elevated temperatures function gradient structure coating on complex profile compression mod surface, realize less, the processing of chipless, complex-curved three-dimensional special welding be shaped, make to improve 3-5 the service life of compression mod doubly, expand the scope of application of compression mod.This manufacturing technology does not produce the three wastes, on environment without impact.
