Abstract
The invention discloses a kind of hot investment casting moulding process, moulding process step is as follows：（1）Wax material is put into mixer, 45-48 DEG C is heated to, pasty state is stirred into；（2）Two metal column moulds are planted into pliability die sleeve by two die sleeve holes of pliability die sleeve respectively, and the three is placed in the die cavity of metal die, then make it close upper and lower mould；（3）By the wax material of pasty state in 3.5 pressure injection moulds of atmospheric pressure, the cast of casting body wax-pattern and cast gate part wax-pattern is carried out respectively, normal temperature is cooled down 30-60 minutes；（4）The upper and lower mould of opening metal mould, is placed on two metal columns mould therein and detaches, and is put into after casting body wax-pattern and the cast gate part wax-pattern demoulding and 22-27 DEG C is cooled in pond, takes out standby；（5）Step（4）The casting body wax-pattern being made is repaired, and cast gate part wax-pattern is bonded together with casting body wax-pattern with 150 DEG C of boiling hot knife then, obtains casting wax-pattern.Operation is simply easy in the technological process, and the packing of casting is good, and overall specification is consistent, and dimensionally stable, Form and position error are small, and high yield rate.
Description
Technical field
The invention belongs to casting technique, and in particular to a kind of hot investment casting moulding process.
Background technology
In present production, mould has obtained being widely applied very much, using particularly extensive in foundry industry.Although casting technique has developing on a large scale very much, it is universal or uses traditional sand casting, metal type cast, and the packing that this kind of method shortcoming is casting differs, and have impact on the durability of casting；Each modular construction of casting of conventional method processing and being not quite similar for specification, complex process, the casting centre repair welding polishing of processing are extremely difficult.
The content of the invention
For the above mentioned problem for overcoming prior art to exist, it is an object of the present invention to provide a kind of hot investment casting moulding process, solves existing wax-pattern complex process, the problem of the casting centre repair welding polishing difficulty of processing.
The hot investment casting moulding process that the present invention is provided, moulding process step is as follows：
（1）Wax material is put into mixer, 45-48 DEG C is heated to, pasty state is stirred into；
（2）Two metal column moulds are planted into pliability die sleeve by two die sleeve holes of pliability die sleeve respectively, and the three is placed in the die cavity of metal die, then make it close upper and lower mould；
（3）By the wax material of pasty state in 3.5 pressure injection moulds of atmospheric pressure, the cast of casting body wax-pattern and cast gate part wax-pattern is carried out respectively, normal temperature is cooled down 30-60 minutes；
（4）The upper and lower mould of opening metal mould, is placed on two metal columns mould therein and detaches, and is put into after casting body wax-pattern and the cast gate part wax-pattern demoulding and 22-27 DEG C is cooled in pond, takes out standby；
（5）Step（4）The casting body wax-pattern being made is repaired, and cast gate part wax-pattern is bonded together with casting body wax-pattern with 150 DEG C of boiling hot knife then, obtains casting wax-pattern.
The hot investment casting moulding process that the present invention is provided, its advantage is that operation is simply easy in the technological process, and the packing of casting is good, and overall specification is consistent, and dimensionally stable, Form and position error are small, and high yield rate；Wax-pattern raw material has saved raw material by that can also be reused after recovery, reduces production cost.
Specific embodiment
With reference to embodiment, the hot investment casting moulding process provided the present invention is described in detail.
Embodiment
The hot investment casting moulding process of the present embodiment, moulding process step is as follows：（1）Wax material is put into mixer, 45-48 DEG C is heated to, pasty state is stirred into；（2）Two metal column moulds are planted into pliability die sleeve by two die sleeve holes of pliability die sleeve respectively, and the three is placed in the die cavity of metal die, then make it close upper and lower mould；（3）By the wax material of pasty state in 3.5 pressure injection moulds of atmospheric pressure, the cast of casting body wax-pattern and cast gate part wax-pattern is carried out respectively, normal temperature is cooled down 30-60 minutes；（4）The upper and lower mould of opening metal mould, is placed on two metal columns mould therein and detaches, and is put into after casting body wax-pattern and the cast gate part wax-pattern demoulding and 22-27 DEG C is cooled in pond, takes out standby；（5）Step（4）The casting body wax-pattern being made is repaired, and cast gate part wax-pattern is bonded together with casting body wax-pattern with 150 DEG C of boiling hot knife then, obtains casting wax-pattern.Operation is simply easy in the technological process, and the packing of casting is good, and overall specification is consistent, and dimensionally stable, Form and position error are small, and high yield rate；Wax-pattern raw material has saved raw material by that can also be reused after recovery, reduces production cost.
Certainly, described above is not limitation of the present invention, the present invention is also not limited to the example above, those skilled in the art, in essential scope of the invention, the change made, remodeling, addition is replaced, should all belong to the present invention it should be understood by those skilled in the art that, the present invention is not limited to the above embodiments, merely illustrating the principles of the invention described in above-described embodiment and specification, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appending claims and its equivalent thereof.
