A molding raw material such as a thermoplastic synthetic resin melt is injected into a mold to form an inflow side socket, an outflow side socket,
The pipe axis connecting the inflow side socket and the outflow side socket is bent at a large angle of 90°, and the outer circumferential axis of the inspection port side socket is perpendicular to the tube axis, and the inner circumferential axis of the inspection port side socket forms a drainage basin that is inclined at an angle θ toward the inflow side with respect to the perpendicular to the tube axis. After molding, the outer mold is divided, and the inner mold for molding the inflow side socket part and the outflow side socket part is extracted. Next, the inspection port side socket molding inner mold and the protruding sleeve are moved downward by a predetermined distance to separate the molded product from the outer mold, and then only the protruding sleeve is moved downward relative to the inspection port side molding inner mold. When the molded product is slid, the molded product is projected through the inspection port side socket part along the inner mold for forming the socket part and is removed. Further, by rotating the inner mold for molding the socket portion and the protruding sleeve about the perpendicular line of the tube axis, left-handed and right-handed products can be manufactured with one mold.
The drainage basin manufactured by the mold of the present invention is buried with the inner circumferential axis of the socket on the inspection port side perpendicular to the ground. In this way, the pipe axis connecting the inflow side socket and the outflow side socket is inclined so that the outflow side is lowered by a predetermined angle θ with respect to the ground. Therefore, when the inspection tube is connected to the inspection port side socket, the inspection tube becomes perpendicular to the ground.

Therefore, the mold of the present invention has a simple structure and can manufacture both left- and right-curved drainage basins with one piece, and in the drainage basin manufactured in this way, the connected inspection tube The upper edge does not protrude from the ground, and the pipe axis connecting the inflow and outflow ports is tilted toward the outflow side to increase the speed of drainage flowing inside the catch basin. This will prevent dirt and mud from accumulating in the drainage basin.
