Sealing structure of heat core box water-cooling shoot plate

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.

Description

technical field [0001] The invention relates to a sealing structure for a water-cooled shooting plate of a hot core box. Background technique [0002] In the prior art, the sealing structure of the water-cooled shooting board of the hot core box includes a shooting board and a plurality of nozzles mounted on the shooting board. The shooting board is composed of upper and lower boards, and there are Flow through the water flow channel of each nozzle in turn, and an annular cooling water channel is opened in each nozzle along its circumference, and the water flow channel communicates with each of the cooling water channels, wherein the upper and lower plates However, since the shooting boards work at high temperature for a long time, the adhesive between the upper and lower boards is easy to denature and fail, so the cooling water will seep from between the boards and water leakage will occur. Contents of the invention [0003] The object of the present invention is to prov...
