Description
Technical field
The present invention relates to Technology of EPC field, the apparatus for pouring of a kind of lost foam casting foundry goods.
Background technology
Lost foam casting is to bond the paraffin similar to casting dimension shape or bubbles model to be combined into model cluster, brushes
After fireproof coating drying, being embedded in vibration molding in drystone sand, pour into a mould under negative pressure, make model gasify, liquid metals occupies
Modal position, forms the novel casting method of foundry goods after solidification cooling.Lost foam casting have gradually precision height, flexible design,
The advantages such as cleaning production, the extensive application cast by mechanical field.
The apparatus for pouring of traditional lost foam casting foundry goods, including vacuum tank, sandbox, lost foam pattern with lead to evaporative pattern
The cast pipeline of model, in wherein lost foam pattern is placed on sandbox, sandbox is built-in cover lost foam pattern dry sand, cast
The upper end of pipeline is provided with charging aperture, so by negative pressure of vacuum, high-temperature metal liquation can be flowed into charging aperture, enter afterwards
In cast pipeline, finally gasifying the lost foam pattern in sandbox, high-temperature metal liquation occupies the position of model.
But, said apparatus there is problems in that 1, typically can smear one layer of fireproof coating in the inner side of lost foam pattern,
And containing moisture in fireproof coating, when high-temperature metal liquation contacts with fireproof coating, substantial amounts of steam can be produced so that system
The foundry goods Hole or the pore that become are more, affect the quality of foundry goods；2, by high-temperature metal liquation cast lost foam pattern time, high temperature
The impulsive force of molten metal is relatively big, and dry sand is higher to the sensitivity of temperature, and fixed-type dry sand easily caves in so that shape
The cast shape become does not meets standard.
Summary of the invention
It is an object of the invention to provide the apparatus for pouring of a kind of lost foam casting foundry goods, the moisture in fireproof coating is entered
Row evaporation, reduces the hole in foundry goods or pore, and prevents dry sand from caving in.
For reaching above-mentioned purpose, the technical scheme is that the apparatus for pouring of a kind of lost foam casting foundry goods, including true
Empty van and sandbox, sandbox is placed on inside vacuum tank, and the side of vacuum tank connects liquid-storing box, and the opposite side of vacuum tank connects to be had
Vacuum machine, is provided with inner side and scribbles fire-resistant lost foam pattern and the cast pipeline connected with lost foam pattern, on liquid-storing box in sandbox
Being provided with fluid-through tube, liquid-storing box is by fluid-through tube and cast pipeline communication；Fluid-through tube include inner tube, outer tube and for outer tube along
Inner tube move up and down rotating mechanism, inner tube is connected with external pipe thread, and outer tube is connected with rotating mechanism, the liquid feeding end of inner tube with deposit
Liquid case is fixing to be connected, and the liquid outlet of inner tube stretches in cast pipeline；The bottom of inner tube is circumferentially provided with liquid outlet, the lower end of inner tube
Portion closes, and is provided with sealing ring between outer tube and inner tube.
When using technique scheme, the present invention arranges inner and outer tubes, by entering outer tube in cast pipeline upper end
Row rotates, and uses outer tube to be blocked by the liquid outlet of inner tube, is then turned on vacuum machine, is in negative pressure state, liquid-storing box in vacuum tank
Interior high-temperature metal liquation sucks inner tube there, owing to the temperature of high-temperature metal liquation is higher, the temperature in vacuum tank and sandbox
Degree gradually rises, and the moisture in fireproof coating in lost foam pattern slowly evaporates, it is simple to dry fireproof coating.So
After, then driving outer tube upwards helical rotation by rotating mechanism, the liquid outlet of inner tube exposes, and high-temperature metal liquation is from liquid outlet
Interior outflow, enters in cast pipeline, finally contacts with lost foam pattern, owing to the temperature of high-temperature metal liquation is higher, disappears
Mould model gasifies, and high-temperature metal liquation occupies the position of lost foam pattern.
The invention have the benefit that
1, in the present invention, by arranging inner and outer tubes, high-temperature metal liquation is temporarily stored in inner tube there, can be to evaporative pattern mould
The fireproof coating of type inwall is dried, can by fireproof coating moisture evaporate, decrease the pore in the foundry goods made or
The defects such as hole, improve the castability of foundry goods.
2, in the present invention, use and high-temperature metal liquation is temporarily stored in inner tube there, high-temperature metal can be advanced with
Sandbox is preheated by liquation so that the dry sand temperature in sandbox slowly raises, with existing unexpected cast high-temperature metal liquation
Comparing, so operation has a temperature buffer stage, reduces the dry sand sensitivity to temperature, it is to avoid dry sand caves in；Additionally, first will
High-temperature metal liquation is temporarily stored in inner tube there, relief high-temperature metal liquation slowly in liquid outlet flow out, high temperature gold
The speed belonging to liquation flowing reduces, reduce the impulsive force of dry sand, it is to avoid the situation that dry sand caves in occurs.
