0.5 °) in the case where also can normally demould.Meanwhile 2~3mm machining allowance compared with the existing technology, present invention proposition 0~
The technical solution of 0.5 ° of draft angle matches the technology for eliminating of rear subcutaneous blowhole, the machining allowance of product external surfaces and inner hole can be set
0.5mm or so is counted, the utilization rate of molten iron is improved, 0.5mm machining allowance means sand-cast loss of weight compared with the prior art
6%~12%, while the manufacturing procedure for processing a rough turn surfaces externally and internally can be reduced in the subsequent mechanical added-time, a production line can
Save a machine tool and a worker；0~0.5 ° of draft angle decreases processing of the casting inner hole in later period machining
