Abstract:
A spray system for spraying a mold release agent and other materials onto inside surfaces of opened metal molds for a die canting machine; comprising:a base plate to which a supply device for distributing and supplying the mold release agent and other materials is mounted, a support member fixed to the base plate, a first cylinder mechanism and a second cylinder mechanism both fixed to the support member, a first slide tube and a second slide tube both fixed to the support member, a first board portion and a second board portion disposed oppositely on both sides of the support member and equipped with spray nozzles for spraying the mold release agent etc., a first holding bar one end of which is fixed to the first board portion and the other end of which slidably pierces and extends through the support member, and a second holding bar one end of which is fixed to the second board portion and the other end side of which slidably pierces and extends through the support member; wherein: the first slide tube is freely expandable between the support member and the first board portion and connects a supply outlet of the supply device and a passage inlet of the first board portion, the second slide tube is freely expandable between the support member and the second board portion and connects the supply outlet of the supply device and a passage inlet of the second board portion, each board portion is so constructed that a nozzle cassette is detachably fitted to a board base plate, the nozzle cassette is equipped with a large number of spray nozzles, and the spray nozzle is connected to the passage inlet of the board portion, each cylinder mechanism is composed of a cylinder body fixed to the support member and a rod expanding from and retracting in the cylinder body, the first cylinder mechanism is adapted to move the first board portion relative to the support member by expanding and retracting the rod in parallel with the first holding bar, and the second cylinder mechanism is adapted to move the second board portion relative to the support member by expanding and retracting the rod in parallel with the second holding bar.
