Description
(1) technical field：
It the utility model is related to the device used in the support class process of producing product in automobile brake system, especially one
Kind is used to prevent insulation construction caused by the thin beam shrinkage porosite of support and spoken parts in traditional operas problem.
Most of support class product is respectively provided with thin beam structure, and wherein thin beam structure design is more elongated, and support is given birth in casting
During production, shrinkage character and cooling effect due to molten iron, two kinds of defects of shrinkage porosite and spoken parts in traditional operas are easily produced.In order to prevent this
Two kinds of problems produce, it is necessary to a kind of insulation construction is positioned over thin beam both sides, and two kinds of defects are prevented by the heat effect of heat insulating block
Produce.
(2) background technology：
In existing support class product foundry production, to solve the shrinkage defect of thin beam, position is produced using in shrinkage porosite
The mode of Quench piece is installed so that the position molten iron solidifies as early as possible, and preventing and treating shrinkage porosite produces.But the mode of installation Quench piece can influence
The cooling velocity of the thin beam portion position, causes the emission form of carbide to change, so as to produce white structure, thin beam air chill
The mechanical performance of thin beam can be influenceed, influences the use function of support；Similarly, since the slim-lined construction of thin beam, thin beam often solidify
It is too fast, cause the generation of spoken parts in traditional operas defect, to prevent air chill, be typically employed in thin beam both sides installation insulation this side of block structure
Formula, but if insulation construction design is improper, it will cause the generation of shrinkage porosite.
In summary, shrinkage porosite is often attended to one thing and lose sight of another, it is not easy to solve simultaneously with white cast iron defect during preventing and treating.
(3) utility model content：
The purpose of this utility model is that providing one kind is used to prevent to be incubated caused by the thin beam shrinkage porosite of support and spoken parts in traditional operas problem
Structure, it can solve the problem that the deficiencies in the prior art, it is a kind of it is simple in construction, easy to make, feasibility is high, can take into account solve spoken parts in traditional operas and
The insulation construction of shrinkage porosite problem.
The technical solution of the utility model：One kind is used to prevent insulation knot caused by the thin beam shrinkage porosite of support and spoken parts in traditional operas problem
Structure, it is characterised in that it includes U-shaped heat insulating block and U-shaped overflow block, and the U-shaped heat insulating block and overflow block are middle concaves, both sides
Convex structure；U-shaped heat insulating block is positioned over the upper end of the thin beam of mould upper bracket, and U-shaped overflow block is positioned over the lower end of the thin beam of support.
Recess is thinner than both sides convex among the U-shaped heat insulating block and U-shaped overflow block.
The length of the U-shaped heat insulating block is more than or equal to thin beam length.
The U-shaped heat insulating block convex thickness is 12mm, and recess thickness is 2~3.5mm, is placed centrally above thin beam.
The length of the U-shaped overflow block is less than thin beam length.
The U-shaped overflow block both sides are respectively smaller than thin beam length 4mm, and convex thickness is 8mm, and recess thickness is 2~
3.5mm, it is placed centrally below thin beam.
The U-shaped heat insulating block and U-shaped overflow block are connected with thin beam with wedge-type shape connection sheet.
The U-shaped heat insulating block and U-shaped overflow block are respectively away from thin beam 5mm.
The course of work of the present utility model：U-shaped heat insulating block in the structure is positioned over the upper end of the thin beam of mould upper bracket, U
Type overflow block is positioned over the lower end of the thin beam of support.In casting process, molten iron enters thin beam, and the low molten iron of the temperature first flowed into first leads to
Meticulous beam flows into the U-shaped overflow block in lower section, and after full of after thin beam, the slightly higher molten iron of temperature flows into the U-shaped heat insulating block of thin beam upper end again.
During molten steel solidification, heat effect caused by the convex structure of U-shaped heat insulating block and overflow block middle concave both sides, the thin beam of support is influenceed
Process of setting so that (position for being also easy to produce shrinkage porosite) first solidifies among thin beam, is solidified behind thin beam both sides, realizes consecutive solidification
Process, so as to reduce the generation of shrinkage porosite；Meanwhile the overflow block of thin beam lower end collects the relatively low molten iron of temperature at thin beam, and it is right
Thin beam insulation, makes thin beam to cool down too fast, produces spoken parts in traditional operas defect.
Superiority of the present utility model：The planform is simple, is easy to make, and occupancy iron water amount is smaller, will not excessive shadow
Ring mould weight and step stays rate.There is practicable effect for preventing and treating thin beam shrinkage porosite and spoken parts in traditional operas, can substantially reduce fraction defective, subtract
Number is had a fling at less, and reduction has a fling at cost, had a clear superiority in terms of product income is improved.
