Claim 0:
1. A mold having a delivery device,
wherein the delivery device comprises:
a first fluid supply path that supplies a first fluid, the first fluid being air;
a second fluid supply path that supplies a second fluid to be mixed with the first fluid for obtaining a mixture, the second fluid being a liquid;
a mixing chamber to which the first fluid supply path and the second fluid supply path are connected, and in which the first fluid and the second fluid are mixed with each other;
a delivery port capable of delivering the mixture from the mixing chamber;
a discharge path provided by being branched from the second fluid supply path; and
a discharge valve interposed in the discharge path so as to be freely opened and closed,
wherein the first fluid supply path is connected to a downstream side end part in a flow direction of the mixing chamber, the second fluid supply path is connected to an upstream side end part in the flow direction of the mixing chamber, the first fluid and the second fluid are mixed in the mixing chamber such that the flow directions of the first fluid and the second fluid are opposed to each other, and the delivery port is provided on a side wall of the mixing chamber between the downstream side end part in the flow direction and the upstream side end part in the flow direction,

wherein the mold comprises:
a delivery nozzle having the mixing chamber, a housing part capable of housing the delivery nozzle, a pressing mechanism that presses the delivery nozzle such that the delivery nozzle can be freely protruded from the housing part into a cavity of the mold; and a control part that controls opening and closing of the discharge valve and controls the pressing mechanism,

wherein the first fluid supply path is provided with a first opening and closing valve interposed so as to be freely opened and closed, the second fluid supply path is provided with a second opening and closing valve interposed so as to be freely opened and closed, and the control part also controls the first opening and closing valve and the second opening and closing valve,
wherein the control part performs:
a mixture delivery process of delivering the mixture from the delivery port by opening the first opening and closing valve, opening the second opening and closing valve, and closing the discharge valve in a protruding state in which the delivery nozzle is protruded into the cavity of the mold by the pressing mechanism;
a first fluid delivery process of delivering the first fluid from the delivery port by opening the first opening and closing valve, closing the second opening and closing valve, and opening the discharge valve in the protruding state; and
a discharge process of discharging the second fluid remaining in the second fluid supply path from the discharge path by maintaining an opening state of the first opening and closing valve, a closing state of the second opening and closing valve, and an opening state of the discharge valve for a predetermined time after the first fluid delivery process has ended in a housing state in which the delivery nozzle is housed in the housing part of the mold by the pressing mechanism.
