Abstract
The present invention is a kind of process structure that riser feeding passage is got through using heating block.Distant and wall is thin between the riser neck of casting pressing port and feeding position, pour rear passage cooled and solidified first, Feeding channel is blocked, feeding position cannot get feeding and to produce shrinkage cavity loose, heating block is embedded in sand mold on Feeding channel, excited generation heat Feeding channel molten iron temperature is not reduced by molten iron high temperature during cast and solidified, the feeding of molten iron in rising head can be obtained by Feeding channel when feeding position molten iron shrinks, prevent the loose generation of feeding position shrinkage cavity.
Description
Technical field
Longer-distance process is effectively reached to feeding a casting rising head in casting technique.
Background technology
In the casting of the volute casting of turbocharger, in order that casting section thickness position is solidifying in cooling
Advanced during Gu by wall thin section position and shrink and molten iron is not solidified in position from wall thickness and pulled away, must just set
The rising head than wall thickness position more Slow cooling is put, feeding is served to wall thickness position.If molten iron is once
Cooled and solidified, it is impossible to flowing will also lose feeding effect, so feeding head be all to try to be arranged to from
Feeding position is close.In the volute casting of turbocharger, the inlet channel of volute is from import to volute
End, from large to small, last junction tube wall forms the triangle such as the tip of the tongue shape to channel internal diameter, is volute
The region of internal wall thickness also larger easy generation shrinkage cavity, rising head can only be arranged on the confined space of outside, mend
The molten iron of contracting, though supercharging of getting angry can be used, because Feeding channel has to pass through the thin place of wall, often by wall
Thin place's molten steel solidification and blocked Feeding channel, the shrinkage cavity to the tip of the tongue position is loose still to happen occasionally.
The content of the invention
The purpose of the present invention is that the structure of Feeding channel is got through using heating block.In riser neck and feeding position
Between Feeding channel casting position, be embedded to heating block during moulding, heating block is by molten iron in pouring molten iron
Temperature activated oxidation produces casting continuous heating of the heat to Feeding channel, and molten iron keeps flowing, rising head
Molten iron can reach the tip of the tongue position in time and carry out feeding.
The technical scheme is that a kind of process structure that riser feeding passage is got through using heating block,
Feeding channel between casting pressing port neck and feeding position, in casting exterior sand mold, embedment heating
Block.
The beneficial effects of the invention are as follows volute cast-internal the tip of the tongue position also can obtain effective feeding, make volute
The shrinkage cavity of the tip of the tongue position it is loose, be resolved.
Described heating block is the type heating of FRK40 × 40 × 20 of Tianjin Kaistar Technology Co., Ltd.'s production
Block.

Embodiment
A kind of process structure that riser feeding passage is got through using heating block.In the riser neck of volute casting 1
Feeding channel B between 4 and feeding position A is embedded to heating block 2 in the outside sand mold of casting 1.
Claims (1)
- A kind of 1. process structure that riser feeding passage is got through using heating block, it is characterised in that：Casting Feeding channel between the riser neck of part and feeding position is embedded to heating block in casting exterior sand mold.
