The mixture of glue and fine sand), then spill fire sand, (be stained with slurry, stucco to be repeated several times, make layer of sand sufficiently thick), treat that it is dried and consolidate
After change, heat to module, wax material is deviate from cast gate, form ghost.By ghost roasting, make firm formwork, will
Metal liquid pours into from cast gate, after condensation, just becomes metal casting.Need mould after cast gate pours into formwork at metal liquid
Metal liquid in shell and formwork carries out the isothermal holding of certain time, primarily serves the effect of feeding, it is to avoid after foundry goods cooling
Internal defect occurs, improves product quality.Prior art is badly in need of a kind of high temperature resistant moushroom valve that formwork can carry out isothermal holding
Heat-preservation cylinder.
Utility model content
The purpose of this utility model is to overcome defect present in prior art, it is provided that formwork can be protected by one
The high temperature resistant moushroom valve heat-preservation cylinder that temperature processes.
For achieving the above object, the technical solution of the utility model there is provided a kind of high temperature resistant moushroom valve heat-preservation cylinder, including
Base plate, described base plate be provided with inside holding cylinder, be socketed in the external thermal insulation cylinder outside inside holding cylinder, inside holding cylinder and external thermal insulation cylinder it
Between air heat-insulation layer；Described inside holding cylinder inwall is attached with heat-preservation cotton, and described plate upper surface is by inside holding cylinder bottom opening
The region covered is attached with heat-preservation cotton, and described external thermal insulation cylinder upper end is provided with upper cover body；Described base plate include center plectane and to
Outer expansion the ceramic insulation circle being sequentially connected with and outer clamping ring, described inside holding cylinder bottom is connected with center plectane, described outside
Heat-preservation cylinder is connected with outer clamping ring, and described ceramic insulation circle is corresponding with air heat-insulation layer position.
By using attemperator described herein, the formwork pouring into a mould metal liquid is placed in inside holding cylinder,
And upper cover body is coordinated snapping with external thermal insulation cylinder；It is thermally shielded by the insulation of heat-preservation cotton again in the space of inside holding cylinder, logical
The heat crossing formwork self distributes, can be at inside holding cylinder inside holding long period (5 to 10 minutes) so that metal liquid is slow
Solidification, improves casting quality.
As preferably, described upper cover body lower end also is provided with heat-preservation cotton, and described external thermal insulation cylinder upper end is provided with joins with upper cover body
The cell body closed, described inside holding cylinder upper end is provided with heat-preservation cotton catch.Such design can improve heat insulation effect further；Cell body
Can facilitate coordinating of external thermal insulation cylinder and upper cover body, heat-preservation cotton catch is possible to prevent heat-preservation cotton upper end-face edge to enter in cell body, shadow
Ring upper cover body and the cooperation snapping of external thermal insulation cylinder.
As preferably, described inside holding cylinder and external thermal insulation cylinder are cylindrical tube.Such design is to scheme
A kind of optimization.
As preferably, described upper cover body is additionally provided with suspension hook.Such design is easy to sling upper cover body, it is to avoid scald
Wound.
Advantage of the present utility model and having the beneficial effects that: by using attemperator described herein, will pour into a mould
The formwork of metal liquid is placed in inside holding cylinder, and with external thermal insulation cylinder, upper cover body is coordinated snapping；Space at inside holding cylinder
It is thermally shielded by the insulation of heat-preservation cotton the most again, is distributed by the heat of formwork self, can be longer at inside holding cylinder inside holding
Time (5 to 10 minutes) so that metal liquid slow solidification, improve casting quality.
