The master frame of an improved styrofoam molding apparatus so that molding and cooling conditions are not changed

摘要

The present invention relates to a styrofoam molding apparatus master frame for spraying steam and cooling water while a mold is mounted for styrofoam molding, and the lengths of the vertical bars of the upper and lower horizontal bars and the left and right horizontal bars formed of a square frame constituting the master frame. It is installed as a reinforcing means consisting of a passage hole for supplying steam or cooling water formed to penetrate in the direction and a tube body formed in communication with the injection hole inside the passage hole, so that more efficient high-pressure injection is achieved, and at the same time, steam and cooling water formed inside the master frame are installed. Through a plurality of injection holes made of small holes for injection, the injection holes are not damaged even by high-pressure injection of steam and coolant.
