Abstract
The invention discloses a method for manufacturing a gypsum silicon rubber precision cast turbocharger diffuser. The method comprises the main processes of: 1, establishing a three-dimensional mold model according to the design data of a vane diffuser, wherein a casting system is taken into consideration in the mold design; 2, manufacturing an integrated metal mold by using a numerical control processing method; 3, casting an integrated silicon rubber male mold in the metal female mold; 4, manufacturing a gypsum female mold shell by using the silicon rubber male mold; 5, baking the gypsum mold to remove moisture therein; 6, completing the casting of the gypsum shell to obtain a diffuser precision cast piece; and 7, cleaning the cast piece, and then thermally treating the cast piece to obtain the cast vane diffuser with finished surface and qualified size. By the method, production process is simple and convenient and the production cost is low; moreover, the method can be used for the batch production of diffusers.
Description
Technical field:
The invention belongs to casting turbocharger diffuser technical field, be specifically related to the preparation method of gypsum silicon rubber hot investment casting turbocharger diffuser.
Background technology
Turbocharger is that modern engine improves power, fuel-economizing and improvement and discharges requisite parts, and diffuser is the critical component that influences the compressor aeroperformance, and its pattern has two kinds of vaneless diffuser and vaned diffusers.That the blade profile of vaned diffuser mainly contains is flat, triangle, thin-walled circular arc type, parabola are carved patterns such as type.
The manufacture method of vane diffuser is for adopting numerical control milling processing at present.Because blade is numerous, processing time consuming is taken a lot of work, and manufacturing cost is very high, is difficult to adapt to the demand of batch process.By the design feature of serious analysis vane diffuser, propose to use the process of hot investment casting to make vane diffuser, parameter control Milling Process part is the hot investment casting part.
Summary of the invention:
The invention provides the preparation method of gypsum silicon rubber hot investment casting turbocharger diffuser, have now in the process of processing vane diffuser in order to solve, because blade is numerous, processing time consuming is taken a lot of work, manufacturing cost is very high, is difficult to adapt to the problem of the demand of batch process.
The present invention can be achieved through the following technical solutions: the preparation method of gypsum silicon rubber hot investment casting turbocharger diffuser, and its main technique step is:
1,, is beneficial to three-dimensional mould model, the mould design running gate system of three-dimensional software design vane diffuser according to the design data of vane diffuser;
2, use numerical-control processing method, make the bulk metal mould according to three-dimensional mould, mould processing;
3, in metal former mould, record bulk silicon rubber male mold;
4, utilize the silicon rubber male mold to make gypsum former formwork;
5, the baking of plaster mold is toasted the gypsum formwork that completes, and removes moisture content wherein;
6, finish the cast of plaster shell at the low-pressure casting machine, obtain complete aluminium alloy diffuser hot investment casting part;
7, heat-treat after the casting cleaning, carry out necessary finishing turning, liquid blasting is carried out on the surface, promptly gets the cast blade diffuser.
The present invention compared with prior art has following beneficial effect: the present invention adopts the method for gypsum silicon rubber hot investment casting to produce vane diffuser, and production process is easy, and production cost is low, can satisfy the production of diffuser in batches.The casting dimension accuracy height, any surface finish has satisfied the designing requirement of eddy pressurizer blade diffuser.
The specific embodiment
The preparation method of gypsum silicon rubber hot investment casting turbocharger diffuser, its main technique step is:
1, according to the design data of vane diffuser, be beneficial to the three-dimensional former mold former of three-dimensional software design vane diffusers such as Proe, UG, consider running gate system and foundry goods shrinkage factor during the mould design;
2, use numerical-control processing method, make the bulk metal mould according to the three-dimensional mould mould processing, mould requires smooth surface;
3, in metal former mould, utilize molded silicon rubber to record bulk silicon rubber male mold;
4, in bulk silicon rubber male mold, record mould gypsum, but utilize the withdrawing pattern characteristic of silicon rubber after solidifying, obtain having the gypsum former formwork of diffuser die cavity feature;
5, the baking of plaster mold is toasted the gypsum formwork that completes, and removes wherein free moisture content and crystallization moisture content;
6, finish the cast of gypsum formwork at the low-pressure casting machine, obtain complete aluminium alloy diffuser hot investment casting part;
7, heat-treat after the cast(ing) surface gypsum formwork cleaning, carry out necessary finishing turning, liquid blasting is carried out on the surface, promptly gets smooth surface, cast blade diffuser that size is qualified.
