[0007] Further, the top of the clamp cylinder casting is symmetrically connected to the riser on the left and right sides, and the riser neck is connected to the machining part of the top of the clamp cylinder casting.
[0008] Further, the bottom of the clamp cylinder casting is symmetrically connected to the casting water feeding pressure edge on the left and right sides.
[0009] Further, the water flow ratio of the riser water feeding pressure edge to the casting water feeding pressure edge is 2:1.
[0010] Further, a sand core is arranged in the middle of the top of the clamp cylinder casting.
[0011] The utility model discloses the beneficial effect: the present application tongs cylinder casting one mould two pieces upper and lower arrangement, and each tongs cylinder casting two top riser, and the casting water pressure side division 1 / 3 flow priority enters tongs cylinder casting bottom, and the remaining 2 / 3 flow water enters the riser, and then realize hot riser feeding, and the molten iron that flows down the riser cannot wash the sand mould of casting bottom cavity, avoid producing sand washing, can realize batch production and improve the quality stability of casting.
