Die casting method for connecting-rod
专利汇可以提供Die casting method for connecting-rod专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a connecting-rod having high fatigue strength and machinability without any deformation at the time of casting by applying facing agent having high heat insulating property on I-shaped body forming part and facing agent having low heat insulating property on big-end and small-end forming parts in cavity in a die.
CONSTITUTION: On the I-shaped body forming part 7 in the cavity, the ceramic series facing agent having relatively high heat insulating property, that is, low heat radiative property, is applied. Then, the big-end forming part 8 and the small-end forming part 9 are beforehand covered so that the ceramic series facing agent is not stuck to the above parts. After that, on the hole cavity 6, graphite water solution having lower heat insulating property, that is, higher heat radiative property than that of the ceramic series facing agent is coated. Therefore, on the I-shaped body forming part 7, the mixing solution of the ceramic series facing agent and the graphite water solution is applied. By this method, the deformation of raw material caused by developing deep chilled structure in the I-shaped body part is prevented and the development of coarse structure in the large-end part and small-end part is prevented and the fatigue strength and the machinability are improved.
