Abstract
PURPOSE: To provide a plurality of ven holes at positions corresponding to the flange among the core rings of the core for molding a faucet of a centrifugal cast- iron pipe having a flange at the inner periphery of the faucet end, so that air and cracked gas of casting sand involved by molten metal can be charged.
CONSTITUTION: A core A for molding a faucet used in centrifugal casting consists of a core ring 1 made of cast iron or the like, and a casting sand part 2 formed by shaping to correspond to the configuration of the inner periphery of the faucet of a casting C and hardened in a state of bonding to the core ring 1. Particularly, in the core ring 1 at positions corresponding to the flange part C' of the inner periphery of the faucet end of the casting C from the inner side to the outer side, there are provided a plurality (generally about 12 to 24 pieces) of vent holes 3 communicating with the axial core in the same direction or slant direction in a rectilinear or bending manner. Particularly, when respective holes 3 are arranged at equally divided positions of the circle, the exhausting operation of air or gas is uniformly carried out. According to the present method, generation of shrinkage and cavity is prevented.
