Abstract
The invention discloses a pressing process for a wax model. The pressing process is characterized by including the following steps that (1) whether a mold, equipment, a pressure instrument and a water temperature gauge are in working states or not is checked, and the mold is assembled and locked; (2) wax is stirred at the temperature of 52-65 DEG C; (3) the stirred wax is placed in a pressing cylinder, a cover is fastened, the pressure is kept at 0.4-0.5 MPa, and the temperature is controlled at 52-56 DEG C; (4) a wax pattern is pressed, specifically, a wax jetting opening is aligned with a wax injecting hole in the mold, a wax gun valve of a wax injector is opened, the wax is jetted into a cavity of the mold, pressure is maintained for 3-5 s, then the valve is closed and a wax gun is moved away; (5) the pressed pattern is placed in water or placed on a workbench to be naturally cooled; (6) the wax model is taken out after the mold is opened, and the wax model is placed in water in time to be cooled; and (7) water and wax scraps of the mold are cleared away, the mold is coated with parting agents, and wax is injected again after the mold is assembled. The pressing process for the wax model is a method with high economic benefits, process parameters of all stages are strictly controlled, the process is reasonably optimized, product performance is improved, procedures are obviously reduced, and the process is simple.
Description
Technical field
The invention belongs to pouring technology field, specifically a kind of pressing process of wax-pattern.
Background technology
In the prior art, the production procedure of investment-casting comprises the compacting of wax-pattern, the compacting of wax-pattern, manufacture and the Baking of shell. There is thick macrostructure in some part, when general mould die mould, because simple in structure, adopt the mode of straight forming, but find that wax-pattern is longer cool time under specific room temperature, and thick most wax material shrinks excessively, causes wax-pattern distortion. Solve problems, generally adopt the method for cold wax stone to solve. But design the casted die mould of the cold wax stone of compacting, cold wax stone is also wanted Design Orientation boss or groove and fixture in die mould simultaneously, and in unitary mould, also want Design Orientation interface and fastener, this just need to manufacture 2 nested structure complexity, mould that processing cost is higher. So the compacting of existing wax-pattern, complex process, economic performance is bad, is badly in need of reasonably optimizing.
Summary of the invention
In view of the deficiency that prior art exists, the object of this invention is to provide a kind of pressing process of enhancing product performance and thering is the wax-pattern of good economy.
The technical scheme that realizes the object of the invention is as follows:
A pressing process for wax-pattern, is characterized in that, this manufacture method comprises the following steps:
(1) check that whether mould, equipment, manometer, water-thermometer be in running order, before matched moulds, with hairbrush even brushing one deck parting compound in mold cavity, die assembly is locked;
(2) stir wax, liquid wax material is added and stirred in wax cylinder, then wax disk(-sc) is put on liquid wax, start mixer and stir into even pasty state wax material, temperature is 52-65 DEG C;
(3) wax material being stirred is packed into fastening good lid in compacting cylinder, then pressurize to pressing in wax cylinder, keep pressure 0.4-0.5MPa, temperature is controlled at 52-56 DEG C;
(4) compacting wax pattern: the casting hole of penetrating on wax mouth Alignment model, open wax injector wax rifle valve, wax material is injected to mold cavity, pressurize 3-5 second, valve-off, removes wax rifle;
(5) die mould is put into water or is placed on workbench naturally coolingly, and need look wax-pattern size cool time, type shape, complexity and determine general 0.8-3 minute;
(6) open mould and take out wax-pattern, put in time water cooling;
(7) cleaning mould moisture, wax bits, brushing parting compound, casting again after assembling.
The pressing process of a kind of wax-pattern of the present invention is a kind of method of high economic benefit, strictly each stage process parameter is controlled, and process optimization is reasonable, has improved properties of product, and operation significantly reduces, and technique is simple.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, and its operating procedure is as follows:
A pressing process for wax-pattern, this manufacture method comprises the following steps:
(1) check that whether mould, equipment, manometer, water-thermometer be in running order, before matched moulds, with hairbrush even brushing one deck parting compound in mold cavity, die assembly is locked;
(2) stir wax, liquid wax material is added and stirred in wax cylinder, then wax disk(-sc) is put on liquid wax, start mixer and stir into even pasty state wax material, temperature is 52-65 DEG C;
(3) wax material being stirred is packed into fastening good lid in compacting cylinder, be strictly on guard against that gas leakage meets accident, then pressurize to pressing in wax cylinder, keep pressure 0.4-0.5MPa, temperature is controlled at 52-56 DEG C;
(4) compacting wax pattern: the casting hole of penetrating on wax mouth Alignment model, open wax injector wax rifle valve, wax material is injected to mold cavity, pressurize 3-5 second, valve-off, removes wax rifle;
(5) die mould is put into water or is placed on workbench naturally coolingly, and need look wax-pattern size cool time, type shape, complexity and determine general 0.8-3 minute;
(6) open mould and take out wax-pattern, put in time water cooling;
(7) cleaning mould moisture, wax bits, brushing parting compound, casting again after assembling.
More than describe preferred embodiment of the present invention in detail. Should be appreciated that those of ordinary skill in the art just can design according to the present invention make many modifications and variations without creative work. Therefore, all technical staff in the art under this invention's idea on the basis of existing technology by logic minute analyse, reasoning or the limited available technical scheme of experiment, all should be by the determined protection domain of claims.
