Abstract
PURPOSE:To improve the roundness and the facial accuracy of the valve body of check valve and facilitate the repair of flawed part in the part to be formed, by dividing a mold for forming the base and body of the valve into two parts; one for forming the valve base and the other for the valve body, and combining them. CONSTITUTION:An injection mold consists of a mold 12 and a mold 13, and the mold 12 has a cavity 15 for forming the projected part 14c of valve body 14, and the mold 13 a prismatically hold cavity 18 for forming the valve base 14a in a mold 16 and a cavity 18 of a truncated conical hole type for forming valve body 14b in a mold 17. Both cavities, 18 and 19, are suitably mated and the melt of molding material is poured through a gate 20. As the cavity 19 for forming the valve body 14b is on a shallow place of the mold 17, its machining is easy, its roundness and facial accuracy are favorable, and in case that the part for forming the valve body 15b is flawed, it is easily repaired or exchanged.
