Abstract

The invention discloses a method for manufacturing a precise cast wax mold. The method comprises the following steps: proportioning a wax material, manufacturing wax ointment, filling wax, and taking off the mold. By adopting the method for manufacturing the wax mold, the quality of the wax mold is greatly improved, the labor and the materials are saved, and the utilization value is increased.

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 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 defect in various degree in manufacturing process, can solve this problem and then makes the quality of foundry goods be greatly improved.

Summary of the invention

There is a lot of problems to solve wax-pattern quality in casting, the invention provides a kind of precision castings method of manufacturing wax mould.

Technical scheme of the present invention is: a kind of precision castings method of manufacturing wax mould, comprises the following steps:

(1) wax material proportioning: paraffin percentage by weight 10%-50%, stearic acid percentage by weight 10%-50%;

(2) the liquid wax prepared in above-mentioned steps and wax bits are delivered to stir in wax cylinder stir, slack wax is stirred fully and evenly, without gas, obtain the slack wax meeted the requirements;

(3) wax cylinder circulating water temperature is pressed to be 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 and cools, available ice block cooling after cooling bay coolant-temperature gage raises;

(5) delivery.

Preferably, described step (2) if in slack wax too rare, appropriate wax bits can be added again, if too thick, a small amount of wax liquid can be added, continue to stir, if slack wax is thick, can mixing time be extended, till mixing out the slack wax meeted the requirements.

Preferably, in described step (4) after casting complete, when taking off casting rifle, want timely shutoff wax injection nozzle, in case slack wax flows backwards make wax-pattern defect.

Preferably, will repair after the wax-pattern taken out in described step (5) cools completely and remove overlap on wax-pattern and parting line, blow clean the wax bits on wax-pattern and moisture content, classification is fitly put on wax-pattern frame.

Beneficial effect of the present invention: make wax-pattern by method of the present invention, the raising that wax-pattern quality can be made to reach very large, has saved man power and material, improve value.

Detailed description of the invention

Embodiment provided by the 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%, stearic acid percentage by weight 10%-50%;

(2) the liquid wax prepared in above-mentioned steps and wax bits are delivered to stir in wax cylinder stir, slack wax is stirred fully and evenly, without gas, obtain the slack wax meeted the requirements;

(3) wax cylinder circulating water temperature is pressed to be 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 and cools, available ice block cooling after cooling bay coolant-temperature gage raises;

(5) delivery.

Embodiment: for requiring strict foundry goods, paraffin percentage by weight 50%, stearic acid percentage by weight 50%, for general foundry goods, paraffin percentage by weight 10%-50%, stearic acid percentage by weight 10%-50%.Process according to the following steps respectively:

1. the liquid wax prepared and wax bits are delivered to stir in wax cylinder and stir, slack wax is stirred fully and evenly, without gas.

2. check whether slack wax meets the requirements (slack wax stirred should be fine and smooth, smooth, do not have graininess, and rare thick moderate), if too rare, appropriate wax bits can be added again, if too thick, a small amount of wax liquid can be added, continue to stir.If slack wax is thick, mixing time can be extended, till mixing out the slack wax meeted the requirements.

3. press wax cylinder circulating water temperature to be 50---55 DEG C, adjust pressure wax pressure (about 4Kg), extremely can increase pressure to 6Kg if having.

4. to there is certain dwell time during casting, timely shutoff wax injection nozzle is wanted when taking off casting rifle, in case slack wax flows backwards make wax-pattern defect, the mould filling wax is positioned in model cooling bay and cools, available ice block cooling after cooling bay coolant-temperature gage raises, the wax-pattern that pressure injection is good can be put in wax-pattern cooling bay and cool.

5. in order to avoid die cavity bonding wax material and difficult delivery, available a small amount of 10# transformer oil or turpentine oil are applied to dies cavity as releasing agent, all could produce next wax-pattern by matched moulds with the water that compressed gas blows off in mould after often producing a wax-pattern simultaneously.

6. wax-pattern will be repaired after cooling completely and remove overlap on wax-pattern and parting line, and blow clean the wax bits on wax-pattern and moisture content, classification is fitly put on wax-pattern frame.

Should carry out clean and maintenance work after mould is finished, temporary transient no mould is put in die frame and preserves.

In this description, the present invention is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, description is regarded in an illustrative, rather than a restrictive.
