Description
Technical field
This utility model is related to casting technology field, the dewaxing device in more particularly to a kind of metal casting moulding process.
Background technology
In metal casting technique, the foundry goods more complicated for structure, general technological process is:According to the chi of foundry goods
The very little wax-pattern for making dimension, applies refractory powder on wax-pattern, then melts to form fire resisting by wax-pattern by high temperature
Molten metal is injected mould casting in refractory material cavity after high-temperature roasting by material casting cavity, refractory material cavity, cold
But afterwards refractory material is removed and then Surface Machining carried out to foundry goods can be prepared by corresponding foundry goods.In current hydrodewaxing step
In, usually wax-pattern being melted by the way of decocting in water or high-temperature steam, this technological requirement has certain humidity and temperature, but this
There is respective shortcoming in both of which:During using decocting in water, if refractory material long-time is immersed in water, fire proofed wood can be caused
Material is partly dissolved in water, produces impact to the quality of product of casting, and the surface quality of product can be very poor, in addition, because water temperature
Most multipotency reaches 100 DEG C, and the dewaxing time is longer, and efficiency is low;When being dewaxed using high-temperature steam, general steam pressure is not less than
0.6MPa, vapor (steam) temperature to more than 160 DEG C, although efficiency comparison is high, but steam oven is high-temperature high-pressure apparatus, danger coefficient ratio
It is higher, and the cost of steam oven and the cost of periodic maintenance in use cause the increase of production cost also than larger.
Utility model content
For problem present in existing dewaxing technique, the purpose of this utility model is to provide in a kind of cast shaping process
Dewaxing device, dewaxing efficiency is high, and equipment cost input is little and substantially without maintenance and very safe using process.
To reach the purpose of this utility model, the dewaxing device in a kind of cast shaping process of the present utility model, including
Boiler, firing equipment and dewaxing kettle, firing equipment are provided with steam inlet, venthole, boiler by pipeline with enter vapour
Mouth connection, venthole are connected by pipeline with dewaxing kettle, are provided with electrically heated rod, which is provided with multiple fin in firing equipment,
During dewaxing, the wax-pattern for being covered with refractory material is placed in dewaxing kettle, and the low temperature water vapour produced in boiler is entered in firing equipment, plus
The electrically heated rod of hot equipment is further heated to design temperature by taking off to workpiece in pipeline to dewaxing kettle to steam
Lasaxing Oilfield.
Preferably, the heating-up temperature of the boiler is at 90 DEG C ± 10 DEG C.
Further preferably, the dewaxing kettle is constructed for square body.
The beneficial effects of the utility model are, the dewaxing device in the cast shaping process, using Low Temperature Steam boiler
Coordinate and the firing equipment of Low Temperature Steam heating and dewaxing kettle can be dewaxed, production efficiency is high, and dewaxing device cost is thrown
Enter it is little and substantially without maintenance, it is very safe using process;And can ensure that the surface quality of casting product.
Description of the drawings
By detailed description below in conjunction with the accompanying drawings, the aforesaid and other objects, features and advantages of this utility model will
Become apparent.Wherein:
Fig. 1 show the composition structure of the dewaxing device in a kind of cast shaping process of an embodiment of the present utility model
Schematic diagram.
Specific embodiment
With reference to accompanying drawing architectural feature of the present utility model and advantage, details are as follows.
A kind of composition structure of the dewaxing device in the cast shaping process of the embodiment of the present utility model shown in Fig. 1
Schematic diagram, which includes boiler 10, firing equipment 20 and dewaxing kettle 30, and firing equipment 20 is provided with steam inlet 22, goes out vapour
Mouth 24, being connected with air intake 22 by pipeline 101 for boiler 10, is provided with electrically heated rod 26 in firing equipment 20, be which is provided with many
Individual fin 261, the venthole 24 of firing equipment 20 are connected with dewaxing kettle 21 by pipeline 102, during dewaxing, are covered with refractory material
Wax-pattern 40 be placed in dewaxing kettle 21, the Low Temperature Steam produced in boiler 10 enter firing equipment 20, the electrically heated rod 26 in which
Design temperature is further heated to steam, the high-temperature steam after heating is entered in dewaxing kettle 30 to therein by pipeline 102
Workpiece (being covered with the wax-pattern 40 of refractory material) carries out dewaxing treatment.
In embodiment of the present utility model, boiler 10 is common steam boiler, and without the need for High Temperature High Pressure, heating-up temperature exists
90 DEG C or so;In addition, the Low Temperature Steam for entering further is heated by the electrically heated rod in firing equipment 20 putting dewaxing
Design temperature, and certain humidity is kept, dewaxing can not only be smoothed out, refractory material can also be made more solid and protected
Stablizing for mold cavity configuration is held, the surface quality of follow-up casting product can be improved.
Further, since firing equipment 20 only to need steam is carried out being heated up to dewaxing temperature required and keep certain humidity,
High pressure will not be produced in firing equipment, therefore, the construction of firing equipment 20 can make square body, and processing cost can be than relatively low.
After the completion of dewaxing, stop boiler and electrically heated rod electrified regulation, can after the temperature in dewaxing kettle is reduced
Dewaxing kettle opens cooling, and the casting cycle of back segment is carried out by refractory material casting mould is taken away.
Dewaxing device in a kind of cast shaping process of the present utility model, being coordinated using Low Temperature Steam boiler can be to low
The steam-heated firing equipment of temperature and the dewaxing kettle being connected with firing equipment are dewaxed, and production efficiency is high, not only avoid height
Potential safety hazard in the high cost investment and use of the steam oven of warm high pressure, and can ensure that the surface matter of the foundry goods after casting
Amount.Dewaxing device cost input of the present utility model is little and substantially without maintenance and very safe using process.
This utility model is not limited to described embodiment, and those skilled in the art is without departing from of the present utility model
Spirit is disclosed in scope, can still be made some amendments or be changed, therefore rights protection scope of the present utility model is with claims
The scope of restriction is defined.
