the water inlet pipe casting mould is characterized in that a forming mould cavity corresponding to two water inlet pipelines and water outlet pipelines of the valve core mounting seat upper pipe joint and the valve core mounting seat is also arranged in the water inlet pipe casting mould in a staggered mode, a water inlet pipe forming core rod and a water outlet pipe forming core rod for forming hollow through holes of the water inlet pipelines and the water outlet pipes are arranged in the forming mould cavity corresponding to the positions of the two water inlet pipelines and the water outlet pipelines, a mounting seat forming core rod for forming the upper pipe joint hollow of the valve core mounting seat, the two water inlet holes and the water outlet holes is arranged in the forming mould cavity corresponding to the position of the upper pipe joint of the valve core mounting seat, after forming, the water inlet pipe forming core rod is drawn out from one side of the two water inlet pipelines, the water outlet pipe forming core rod is drawn out from one side of the water outlet pipeline, the mounting seat forming core rod is drawn out from the upper part of the valve core mounting seat, and the formed first water inlet pipe, the second water inlet pipe and the valve core mounting seat are obtained through cooling;
and S2, finally, placing the first and second formed water inlet pipes and the formed valve core mounting seat into a mold cavity of a plastic inner valve core body forming mold, placing the valve core mounting seat in the middle of the mold cavity, respectively arranging the first and second water inlet pipes in the mold cavity at two sides of the valve core mounting seat, casting the formed outer water inlet and outlet transverse pipes again by using the first and second formed water inlet pipes and the valve core mounting seat as inner core bodies of the outer water inlet and outlet transverse pipes after positioning, and cooling to obtain the formed plastic inner valve core body.
