Fire prevention it bites and the frame production production frame which it bites

摘要

The present invention relates to a mold for manufacturing a fire door door frame, in the mold frame for manufacturing a fire door door frame is equipped with a press punch is mounted to the upper portion for the manufacture of the fire door, the lower portion of the press punch is formed. A bent portion having an angle symmetrically upward toward the bottom of the punch is formed, and an upper portion of the mold is formed to have a protrusion formed at an angle corresponding to the bent portion, and an inclined surface formed at the one side inclined surface. A mounting groove having an inclination of the right angle and a groove is formed, and the mounting groove of the mold is equipped with an auxiliary mold formed at right angles to one side and protruding a predetermined section during mounting, wherein the auxiliary mold is a win of the press punch. When descending, the upper part of the mold mounting groove and the lower part of the auxiliary mold can be quickly returned to the designated position. In that the mounting ring is characterized.;According to the present invention, it is possible to easily manufacture the door frame of the fire door without being bound by the length of the metal plate for manufacturing the fire door, fire hydrant, etc., as well as the production process of the mold frame is simplified, thereby reducing the mass production and production costs.;Metal plate, press punch, mold, auxiliary mold, spring.
