Abstract
The present invention sets the structure for block of getting angry for a kind of increase riser feeding distance at the top of rising head.When carrying out feeding to volute inside using common side rising head, feeding purpose is not reached because riser neck is remote away from feeding position distance.Block of getting angry is set at the top of present rising head, and one layer of sheet metal is cladded outside block of getting angry.It is heated to generate heat after block of getting angry contact molten iron and gets angry, the mobility that rising head molten iron can be increased moves to feeding position, the block that makes to get angry again simultaneously can be influenceed rising head and be full of molten iron by the sheet metal barrier molten iron too fast generation gas that will not be heated, act on the feeding of rising head to bring into normal play, casting can obtain effective feeding.
Description
Background technology
The turbine case casting of turbocharger of motor, it is not only complicated, and also wall thickness is also uneven from each other, phase
Difference is very big.Wall thickness such as the intake and exhaust volute passage of volute is thinnest part, and air inlet flange and turbine installation site etc.
It is wall thickness maximum, to prevent casting molten iron cooling velocity is uneven from producing shrinkage cavity or loose, is put at wall thickness
Feeding head is put to carrying out feeding at wall thickness.When designing rising head position be all make rising head and treat feeding position distance it is most short with up to
To effective feeding, and some privileged sites structures of volute cannot meet this principles and requirements.The volute passage end of each volute
The wall thickness of Duan Hewo roads import junction is to produce the loose emphasis of shrinkage cavity shaped like the tip of the tongue, and inside spiral case, but can not
Rising head is closely set, scraps casting to happen occasionally because the shrinkage cavity at this position is loose.
The content of the invention
The present invention is a kind of the structure of block of getting angry to be set at the top of rising head for increase riser feeding distance.To the volute the tip of the tongue
Position sets feeding head, can only use side rising head.Place one at the top of rising head to get angry block, block contact of getting angry when cast is high
Warm molten iron, which can generate heat, produces 0.4-0.6Mpa gas, promotes molten iron to be flowed to feeding position.When gas pressure caused by block of getting angry
Power is excessive, can also hinder molten iron to flow into rising head, therefore clads one layer of sheet metal in block appearance of getting angry, and being got angry with delay, block is heated to be made
Gas forming amount incrementally increases.
The technical scheme is that block of getting angry is placed on the top of volute external mold side rising head, wrapped outside block of getting angry
Multiple one layer of sheet metal.
The distinguishing feature of the present invention is when volute casting pouring molten iron, emits intraoral contacted full of molten iron and is got angry at the top of rising head
During block, the sheet metal outside block of getting angry is melted first, when sheet metal, which is melted block of getting angry, is produced gas by heat lag, emits oral area
Position has been filled with molten iron, now emits the feeding position that intraoral molten iron is pushed to volute, has been considerably improved the mobility of feeding molten iron,
Distant feeding position is effectively set to obtain feeding, percent defective is declined.
Described block of getting angry is got angry block for 24 × ∮ of ∮ 30 × 34 that Tianjin Kaistar Technology Co., Ltd. provides.
Brief description of the drawings
Fig. 1 is to get angry block in rising head position placement schematic diagram.
Fig. 2 is block appearance cladding sheet metal schematic diagram of getting angry.
Brief description of the drawings：1st, get angry block；2nd, sheet metal cladding；3rd, side rising head；4th, casting external mold.
Embodiment
It is a kind of that for increase riser feeding distance, the structure for block of getting angry is set at the top of rising head.
Block 1 of getting angry is placed on the top of the side rising head 3 of volute external mold 4, and one layer of sheet metal cladding is cladded outside block 1 of getting angry
Layer 2.
Claims (2)
1. a kind of set the structure for block of getting angry for increase riser feeding distance at the top of rising head, it is characterized in that：Block of getting angry is placed
At the top of volute external mold side rising head.
2. it is according to claim 1 it is a kind of for increase riser feeding distance, the structure of block of getting angry is set at the top of rising head,
It is characterized in that：One layer of sheet metal is cladded outside block of getting angry.
