Inner wall surface be provided with heat-insulation layer and its side wall and be provided with hinged door, the hinged door is provided with tight locking button, the formwork rising-falling tone
Section component includes leading screw, wire rod thread set, graduated scale and the U-shaped support frame for holding up formwork, is connected on the U-shaped support frame
There is wire rod thread set with two for the arc positioning snap ring positioned to formwork, the lower end of the screw mandrel passes through wire rod thread
Cover and penetrate the screw mandrel positioning hole positioned at material bottom of the barrel, the upper end of screw mandrel is connected with rotary handle, the upper end of the graduated scale
It is connected on material barrel upper cover plate, the side of the U-shaped support frame is connected with the indicator for indicating graduation chi.
Preferably, the heat-insulation layer is made up of insulation cotton material.
Preferably, the positioning snap ring is semicircle.
Preferably, the material barrel is made up of ferrous material.
Compared with prior art, the beneficial effects of the invention are as follows：
In the present invention, staff's rotary screw, and then drive U-shaped support frame to be moved up and down along material barrel inwall, from
And adjust the formwork in positioning snap ring up and down, and by indicator before and after adjustment on the scale position come determine formwork movement away from
From accordingly even when different formworks are highly variant, ensureing that potting syrup reaches the formwork cast gate time one by adjusting formwork highly
Cause, it is ensured that the temperature that potting syrup reaches formwork is consistent；On the other hand, when needing raising potting syrup to enter the temperature of formwork,
The distance of formwork need to only be moved up to shorten the time that potting syrup enters formwork；The inner wall surface of material barrel is provided with heat-insulation layer,
After Turbine Casting cast, be advantageous to the integral heat sink of Turbine Casting slowed down, make that Turbine Casting solidifies and crystal grain is grown in one
Completed in the relatively small environment of individual thermograde, so as to suppress the column crystals growth of casting, reduce column crystal length, improve production
The qualification rate of product.
