題を生起させている。Further, the nozzle pipe B is screwed and fixed.
When a nozzle pipe B that needs to be replaced occurs in the group, or when the nozzle pipe B occurs near the center of the nozzle pipe group, the replacement work cannot be performed unless other surrounding nozzle pipes B are removed. There is a problem, the workability of screwing, fixing, and replacing the nozzle pipe B is extremely poor. Even if the nozzle pipe B that needs to be replaced is generated, the nozzle pipe B can be sprayed, adhered, and compressed with a compressed air without replacement. In some cases, the injection is continued, which eventually causes problems such as the occurrence of defective molded products.
