Abstract
The casting process of cylinder cap of engine includes one horizontal cast mold fabrication, vertical casting and vertical cooling. There is chill block embedded in the thick wall part and the sprue and riser head is on the side of cylinder cap. The said process has a finished product rate higher than 95% and a sprue and riser head system weight lower than 20 wt% of the casting.
Description
The invention belongs to foundry engieering, be specifically related to casting process of cylinder cap of engine.
Traditional casting process of cylinder cap of engine is to take " flat do, flatly water, flat cold ", and the dead head design is at the not ipsilateral of foundry goods.This technology running and feeding system weight accounts for the 30-40% of cylinder head casting weight, and since cylinder cap everywhere wall thickness do not wait, this technology causes shrinkage porosite, the shrinkage cavity of foundry goods easily, percent defective is up to 30-40%, thereby makes product cost higher.
The objective of the invention is to propose a kind of casting process of cylinder cap of engine that reduces the dead head loss, reduces percent defective.
Purpose of the present invention realizes by following technology: the mold at cylinder cap heavy wall position is embedded with an amount of chill, with the cooling velocity at even cylinder head casting different-thickness position, foundry goods integral body is solidified simultaneously, reduces the casting stress in the foundry goods.Adopt simultaneously flatly do, upright casting, upright cold pouring technology, utilize the deadweight gravity of molten iron, to reduce shrinkage porosite, the shrinkage cavity in the foundry goods, reach the percentage that reduces the shared casting weight of running and feeding system weight.
Adopt casting process of cylinder cap of engine of the present invention, can make running and feeding system weight only account for below 20% of casting weight, casting yield reaches more than 95%, effectively reduces the cost of product.
With this explained hereafter east wind 135 automobile cylinder caps, the mold at the wall thickness position of cylinder cap is embedded with 24-28 piece chill, and dead head is arranged on the cylinder cap side, molten iron temperature 1350 degree, flat back upright casting, upright cold, foundry goods gross weight 43-46 kilogram, the running and feeding system 9-11 kilogram carried out of mold.Flat back upright casting, upright cold, foundry goods gross weight 43-46 kilogram, the running and feeding system 9-11 kilogram carried out.
With this explained hereafter 4100 agricultural vehicle Diesel engine cylinder caps, mold is embedded with 24 blocks of chills at the wall thickness position of cylinder cap, the dead head design is in the cylinder cap side, molten iron temperature 1350 degree, after mold is put down and is carried out, upright casting, upright cold, gained foundry goods gross weight 29-31 kilogram, running and feeding system weight 5.5-6.0 kilogram.Casting yield is more than 95%.
Claims (1)
1, a kind of casting process of cylinder cap of engine is characterized in that in the mold thick position of cylinder cover wall is embedded with the chill of an amount of quantity, and dead head designs in the cylinder cap side, adopt flatly do, upright casting, upright cold technology.
