Description
Technical field
It the utility model is related to a kind of turbine case with heating bag.
Background technology
Traditional turbine case side riser technique, for feeding, increases cast boss size, actual according to casting on casting
Need directly to thicken to realize feeding a casting, there are following main problem for it：
1st, casting weight increases, uneconomical；
2nd, client is persuaded to change cast model, application increases cast boss；
3rd, the cast boss that can not forever leave, which needs to process, to be removed, and is added process, is improved cost；
4th, also need to coordinate increase chill to use sometimes.
The content of the invention
A kind of the purpose of this utility model is to overcome above-mentioned deficiency, there is provided turbine case with heating bag.
What the purpose of this utility model was realized in：
A kind of turbine case with heating bag, it is characterised in that it includes turbine case main body and side riser, the turbine
Connected between shell main body and side riser by pouring into a mould boss, the turbine case master below the cast boss and near cast boss
Heating bag is provided with below body, it is casting solidification later stage tongue isolated region to heat at bag in corresponding turbine case main body, positioned at pouring
The collar extension of heating bag below note boss, which is set, to be had the gap into water.
As a preferred embodiment, the height of the heating bag top surface distance cast boss below cast boss is 5.8mm, position
The height of heating bag below cast boss is 8.8mm.
As a preferred embodiment, the thickness that gap enters water is 0.5mm.
As a preferred embodiment, the heating bag top surface below turbine case main body is apart from the height of turbine case main body
7.9mm, heating bag medial surface below turbine case main body are 5.5mm apart from the distance of turbine case body outer wall, whirlpool at this
The sand layer thickness of wheel shell main body be less than turbine case main body other height at wall thickness.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is since the design of heating bag causes casting local location to be later than isolated region solidification, so as to get through thin
Feeding channel at wall, can obtain effective liquid feeding so that casting obtains effective feeding at side riser.Heating bag can
Heat will be baked below cast boss, and extend the side riser feeding liquid time, realize consecutive solidification.The utility model mitigates casting design
Weight, improves casting yield rate, processing iron water amount must in the case of, can more pouring cast part quantity per iron clad water；Casting
Inherent quality is stablized；Reduce chill usage amount.

Embodiment
Referring to Fig. 1-Fig. 4, a kind of turbine case with heating bag that the utility model is related to, it includes turbine case main body 1
And side riser 2, connected between the turbine case main body 1 and side riser 2 by pouring into a mould boss 3, cast boss 3 lower section with
And the lower section of turbine case main body 1 near cast boss 3 is provided with and heats bag 4, is in corresponding turbine case main body 1 at heating bag 4
Casting solidification later stage tongue isolated region 6, the height positioned at the heating bag 4 top surfaces distance cast boss 3 of 3 lower section of cast boss are
5.8mm, the height positioned at the heating bag 4 of 3 lower section of cast boss is 8.8mm, positioned at the outer of the heating bag 4 for pouring into a mould the lower section of boss 3
Mouth sets and has the gap into water 5, and the thickness that gap enters water 5 is 0.5mm, the 4 top surface distance of heating bag positioned at the lower section of turbine case main body 1
The height of turbine case main body 1 is 7.9mm, and 4 medial surface of heating bag positioned at the lower section of turbine case main body 1 is apart from turbine case body outer wall
Distance be 5.5mm, at this sand layer thickness of turbine case main body 1 be less than turbine case main body 1 other height at wall thickness.
It is a kind of with heating bag turbine case, heat the design of bag so that casting local location be later than isolated region solidification, from
And Feeding channel at thin-walled has been got through, effective liquid feeding can be obtained at side riser so that casting obtains effective feeding.
Bag is heated to extend the side riser feeding liquid time, realize consecutive solidification roasting heat below cast boss.One kind is with heating
The turbine case of bag mitigates casting design weight, improves casting yield rate, processing iron water amount must in the case of, can per iron clad water
With more pouring cast part quantity；The internal quality of casting is stablized；Reduce chill usage amount.
