Abstract

PURPOSE: To facilitate integral molding of pump casing and the like with synthetic resin in such a way that a cylindrical body with upper end opening facing to priming mouth and lower end opening aligned with discharge passage is interconnected with pump casing which forms air/water separating chamber.
CONSTITUTION: Discharge passage 9 and priming mouth 7 are disposed adjacent respectively to upper and lower end openings of cylindrical body 10 on the same axis as that of body 10, and priming mouth 7 is somewhat overlapped on lower opening 6a of air/water separating chabmer 6. Therefore, when air/water separating chamber 6 is molded with synthetic resin, it can be integrally formed merely by drawing apart lower mold for molding separating chamber 6 and discharge passage 9 from upper mold for molding priming mouth 7 and cylindrical body 10 in either one of upward and downward directions. Moreover, since priming mouth 7, discharge passage 9, and cylindrical body 10 are disposed on a common axis, threaded portion 7a of priming mouth 7 can be molded by rotating one section of upper mold which section is adapted to be drawn out of upper mold in the while the section forms an annular space 12 around cylindrical body 10 as it is rotated with respect to the common axis.
