Abstract

The open a kind of precision castings method of manufacturing wax mould of the present invention, comprises the following steps: wax material proportioning, makes slack wax, casting, delivery.Make wax-pattern by the method for the present invention, wax-pattern quality can be made to reach the biggest raising, saved man power and material, improve value.

Description

A kind of precision castings method of manufacturing wax mould

Technical field

The invention belongs to aluminum alloy die-casting technological technical field, particularly to a kind of precision castings method of manufacturing wax mould.

Background technology

At present, in metal casting technique, the making of wax-pattern is extremely important, but often there is different journey in manufacturing process The defect of degree, can solve this problem and then makes the quality of foundry goods to be greatly improved.

Summary of the invention

A lot of problems occur in order to solve wax-pattern quality in casting, the present invention provides a kind of precision castings wax-pattern making side Method.

The technical scheme is that a kind of precision castings method of manufacturing wax mould, it is characterised in that: comprise the following steps: (1) Wax material proportioning: paraffin percentage by weight 10%-50%, stearic acid percentage by weight 10%-50%；(2) will above-mentioned steps prepare Liquid wax and wax bits deliver to stirring in stirring wax cylinder, make slack wax stirring fully and uniform, depletion of QI, obtain the slack wax meeted the requirements, stir Stirring the most in the same direction when mixing, mixing speed is 30cm/s, and in whipping process, heating-up temperature is 30-40 DEG C；(3) pressure wax cylinder Circulating water temperature is 50-55 DEG C, presses wax pressure 3-6Kg；(4) dwell time 1-2 hour during casting, the mould filling wax is positioned over Model cooling bay cools down, available ice block cooling after cooling bay coolant-temperature gage raises；(5) delivery；Described step (5) is taken out After wax-pattern cools down completely, first dry up the wax bits on wax-pattern and moisture, then remove the overlap on wax-pattern and typing with pocket knife finishing Line, at the overlap remained with sand papering and the vestige of parting line, blows clean the wax bits on wax-pattern and moisture content, classification the most again It is neatly arranged on wax-pattern frame.

Further, described step (2) if in slack wax the dilutest, appropriate wax bits can be added again, if the thickest, can add few Amount wax liquid, continues stirring, if slack wax is thick, can extend mixing time, till mixing out the slack wax meeted the requirements.

Further, in described step (4) after casting complete, when taking off casting rifle, to block wax injection nozzle in time, with wax control Cream flows backwards and makes wax-pattern defect.

Beneficial effects of the present invention: make wax-pattern by the method for the present invention, can make wax-pattern quality reach the biggest raising, joint About man power and material, improves value.

Detailed description of the invention

The embodiment providing the present invention is described in further detail:

A kind of precision castings method of manufacturing wax mould, comprises the following steps: (1) wax material proportioning: paraffin percentage by weight 10%-50%, firmly Fat acid percentage by weight 10%-50%；(2) stir in delivering to stir wax cylinder by the liquid wax prepared in above-mentioned steps and wax bits, make wax Cream stirs fully and uniform, depletion of QI, obtains the slack wax meeted the requirements, stirs the most in the same direction during stirring, and mixing speed is 30cm/s, in whipping process, heating-up temperature is 30-40 DEG C；(3) pressure wax cylinder circulating water temperature is 50-55 DEG C, presses wax pressure 3- 6Kg；(4) dwell time 1-2 hour during casting, the mould filling wax is positioned in model cooling bay cooling, when cooling bay water temperature Degree is available ice block cooling after raising；(5) delivery；After the wax-pattern taken out in described step (5) cools down completely, first dry up on wax-pattern Wax bits and moisture, then with pocket knife finishing remove the overlap on wax-pattern and parting line, overlap remain with sand papering and divide The vestige of molded line, blows clean the wax bits on wax-pattern and moisture content the most again, and classification is neatly arranged on wax-pattern frame.

Described step (2) if in slack wax the dilutest, appropriate wax bits can be added again, if the thickest, a small amount of wax liquid can be added, continue Continuous stirring, if slack wax is thick, can extend mixing time, till mixing out the slack wax meeted the requirements.

In described step (4) after casting complete, when taking off casting rifle, to block wax injection nozzle in time, in case slack wax flows backwards makes wax Mould defect.

In this description, the present invention is described with reference to its specific embodiment.But it is clear that still may be made that Various modifications and alterations are without departing from the spirit and scope of the present invention.Therefore, description is considered as illustrative rather than limits Property processed.

Claims

1. a precision castings method of manufacturing wax mould, it is characterised in that: comprise the following steps: (1) wax material proportioning: paraffin weight percent Ratio 10%-50%, stearic acid percentage by weight 10%-50%；(2) deliver to stir wax cylinder by the liquid wax prepared in above-mentioned steps and wax bits Interior stirring, makes slack wax stirring fully and uniform, depletion of QI, obtains the slack wax meeted the requirements, stir the most in the same direction during stirring, Mixing speed is 30cm/s, and in whipping process, heating-up temperature is 30-40 DEG C；(3) pressure wax cylinder circulating water temperature is 50-55 DEG C, pressure Wax pressure 3-6Kg；(4) dwell time 1-2 hour during casting, the mould filling wax is positioned in model cooling bay cooling, when cold But available ice block cooling after pond water temperature raises；(5) delivery；After the wax-pattern taken out in described step (5) cools down completely, first dry up Wax bits on wax-pattern and moisture, then remove the overlap on wax-pattern and parting line, remain with sand papering with pocket knife finishing Overlap and the vestige of parting line, blow clean the wax bits on wax-pattern and moisture content the most again, and classification is neatly arranged on wax-pattern frame.

Precision castings method of manufacturing wax mould the most according to claim 1, it is characterised in that: described step (2) if in slack wax The dilutest, appropriate wax bits can be added again, if the thickest, a small amount of wax liquid can be added, continue stirring, if slack wax is thick, stirring can be extended Time, till mixing out the slack wax meeted the requirements.

Precision castings method of manufacturing wax mould the most according to claim 1, it is characterised in that: casting complete in described step (4) After, to block wax injection nozzle when taking off casting rifle in time, in case slack wax flows backwards makes wax-pattern defect.
