Casting material cylinder cooling mechanism

The utility model discloses a casting material cylinder cooling mechanism which comprises an embedded sleeve arranged in a material cylinder with a feeding port, an opening structure matched with the feeding port is formed on the embedded sleeve, the surface of the embedded sleeve is concaved inwards to form a bent water channel, and the water channel is arranged in the material cylinder. The two ends of the water channel form a first semicircular opening in the end face of the embedded sleeve, a second semicircular opening matched with the first semicircular opening is formed in the end face of the material cylinder, the first semicircular opening and the second semicircular opening form a water hole, and a water guide pipe is detachably arranged in the water hole; the problems that in a material cylinder structure in the prior art, a cooling water path is arranged on the inner wall of a material cylinder, due to the fact that the material cylinder is generally thick, the heat dissipation capacity of the mat
