Abstract
The present invention is a kind of structure that heating block is placed at the top of casting pressing port and prevents that rising head from binding.When cast, appearance condensation crust binds at the top of molten iron in rising head, when molten iron feeding outward in rising head, emits intraoral aobvious vacuum state, influences feeding effect.Heating block is placed at the top of rising head, high temperature liquid iron persistent fever is met, makes rising head appearance be not easy quickly to solidify, the normal feeding of molten iron in rising head can be promoted, is prevented because feeding casting generation shrinkage cavity not in place is loose.
Description
Technical field
The technical measures that feeding head in casting technique is bound using heating block solution rising head.
Background technology
In the casting technique of turbocharger of motor volute, because the wall thickness of volute is extremely uneven, differ mutually very
Greatly, also difference is very big for each position cooling velocity, and the molten iron at wall thickness often advances cooling meat by the thin place of wall and pulls away molten iron,
It is loose that shrinkage cavity is formed at the thin place of wall.Rising head typically is set to being also easy to produce shrinkage cavity or porous spot, because of the larger cooling of rising head volume
Slowly, molten iron can be supplemented to shrinkage cavity position, makes that shrinkage cavity or loose will not be produced at wall thickness.Rising head is designed as greatly cylinder, iron
Water fills type to model again often over rising head, if rising head top surface especially blind riser cooled and solidified, forms one layer
Shell, when internal molten iron, which starts flowing, tends to feeding, vacuum will be formed inside rising head, hinder molten iron or reduce rising head benefit
Contracting acts on, and generation shrinkage cavity position is cannot get effective feeding and is produced casting and scrap.
The content of the invention
The purpose of the present invention is to be formed to bind for solution feeding head outer wall cooled and solidified to influence feeding effect, in rising head
Top sets heating block, reduces cooling velocity at the top of rising head, feeding can be completed before binding.
The technical scheme is that heating block is set at the top of the rising head of casting side.
Promote heating at the top of rising head the beneficial effects of the invention are as follows heating block and reduce cooling velocity, molten iron energy in rising head
Smooth flow reaches feeding position, and obtaining feeding at volute wall thickness eliminates the defects of shrinkage cavity is loose.
Described heating block is the type product of FRK40 × 40 × 20 that Tianjin Kaistar Technology Co., Ltd. provides.
Brief description of the drawings
Fig. 1 volute casting heating blocks are in side rising head installation site figure.
Brief description of the drawings：1st, casting；2nd, side rising head；3rd, heating block；4th, riser neck.
Embodiment
Heating block is set to prevent the structure that rising head binds at the top of rising head.At the top of the side rising head 2 of casting 1, hair is set
The hot side rising head 2 of block 3 is connected by riser neck 4 and casting 1.
Claims (1)
1. a kind of set heating block to prevent the structure that rising head binds at the top of casting pressing port, it is characterised in that：Emitted in casting side
The top of mouth, sets heating block, and side rising head is connected by riser neck with casting.
