Patent number: 5385196Abstract: In a spray method for spraying and applying a powdery mold coating agent onto both inside surfaces of a movable metal mold and a stationary metal mold for a permanent mold casting device, a spray method of permanent mold casting powdery mold coating agent in which a spray head provided with an electrostatic spray gun is fit to a feeding port so as to shut it tightly and a suction head connected to a suction pump is fit to a riser port so as to shut it tightly under a state where the movable metal mold and the stationary metal mold are closed. An inside of cavity is sucked by the suction pump through the riser port so as to produce a pressure difference between inside and outside of the cavity, and a powdery mold coating agent supplied from a powdery mold coating agent feeding device to the electrostatic spray gun is discharged from the electrostatic spray gun by means of the above pressure difference so as to be electrostatically adsorbed onto the inside surfaces of the foregoing both metal molds.Type: GrantFiled: October 7, 1993Date of Patent: January 31, 1995Assignee: Hanano CorporationInventor: Takashi Hanano

Patent number: 5383775Abstract: A powdery mold release agent spray device including a nozzle having spray ports on its tip end side wall, a nozzle having spray ports on its tip end surface and shut pins, all of which are assembled in through holes made on both metal molds. The spray ports of the former and latter nozzles are exposed to cavity inside at time of spraying work, the spray ports of the former and latter nozzles are located in the through holes and the cavity is isolated from the spray ports of the latter nozzle by the shut pin. By using this spray device, a powdery mold release agent can be sprayed onto inside surfaces of the metal molds without exception, economically and without worsening a work environment.Type: GrantFiled: February 3, 1994Date of Patent: January 24, 1995Assignee: Hanano CorporationInventor: Takashi Hanano
