Example Embodiment

[0009] The specific structure and working principle of the present invention will be further described below in conjunction with the accompanying drawings.

[0010] Referring to Figures 1-2, a sealing structure for a water-cooled shot plate of a hot core box includes a shot plate 6 and a plurality of nozzles 2 mounted on the shot plate 6. The shot plate 6 is combined by upper and lower plates The water flow channel 3 is formed on the joint surface 7 of the upper and lower plates and flows through each nozzle in turn. Specifically, in Figure 1, the water flow channel 3 is opened on the lower plate 5 and the upper plate is combined. On the upper plate surface, each nozzle 2 is provided with an annular cooling water channel 8 along its circumference, surrounding the sand shooting channel 9 in the nozzle 2, for cooling the core sand in the nozzle 2 and preventing the core sand from solidifying , block the sand shooting channel 9, the water flow channel 3 is communicated with each ...

Abstract

The invention discloses a sealing structure for a water cooling nozzle plate of a hot core box. The structure comprises a nozzle plate and a plurality of nozzles arranged on the nozzle plate, wherein the nozzle plate is formed by the connection of an upper plate and a lower plate, the connection surface of the upper plate and the lower plate is provided with a water current channel orderly connected with each nozzle, a ring-shaped cooling water channel is arranged in each nozzle along the circumferential direction, the water current channel is communicated with each cooling water channel, the joint between upper plate and the lower plate is provided with a sealed waterproof sealing strip, and the water current channel and the cooling water channels which are communicated are arranged in a closed zone of the sealing strip; by the water current channel, the cooling water is supplied to the cooling water channels in the nozzles to cool down the sand cores in the nozzles and prevent the solidification of the sand cores. Because the channels the cooling water flows by are limited in the enclosed zone of the waterproof sealing strip, the cooling water does not leak out of the sealing strip, thereby effectively avoiding the water leakage.
