Abstract

DC60 (17/06/57) This exposed casting machine defines the boundaries of the upper and lower casting cavities as the upper and lower lid flasks 12, 13, with coupling plate 11 sandwiched between them, are rotated from their horizontal to their vertical positions. The upper compression assembly 14 can be inserted into the upper lid flask 12 by a pressure plane opposite the top face of coupling plate 11. This pressure plane defines the boundaries of the casting cavity with the top face of coupling plate 11 and the upper lid flask 12. The axial rotating frame 23 supports the upper and lower lid flasks 12, 13, with coupling plate 11 sandwiched between them, and the upper compression assembly 14 in such a way that the parts rotate synchronized between the horizontal position, where the pressure plane of the upper compression assembly 14 is vertically oriented downwards, to the vertical position where this pressure plane is horizontally oriented. The filling frame, which... The vertical clamping element is attached to the lower lid flask 13 when the upper and lower lid flasks 12, 13, with the coupling plate 11 sandwiched between them, are in a vertical position. The lower clamping assembly 16 has a pressure plane which is oriented horizontally and can be inserted into the filling frame and the attached lower lid flask 13. This pressure plane of the lower clamping assembly 16 defines the boundaries of the mold cavity along with the bottom face of the coupling plate 11, lower lid flask 13, and filling frame 15. This exposed molding element defines the boundaries of the upper and lower mold cavities while the upper and lower lid flasks 12, 13, with the coupling plate 11 sandwiched between them, are rotated from their horizontal to their vertical positions. The upper clamping assembly 14 can be inserted into the upper lid flask 12 with its pressure plane opposite to it. The top face of the 11 coupling plates provides this pressure, defining the boundaries of the mold cavity with the top face of the 11 coupling plate and the top flask 12. The axially rotating frame 23 supports the top and bottom flasks 12, 13, with the 11 coupling plate sandwiched between them, and the top clamping assembly 14, in such a way that the section rotates synchronously between horizontal positions, where the pressure plane of the top clamping assembly 14 is oriented vertically downwards, to a vertical position where this pressure plane is oriented horizontally. The vertically fixed filling frame is adjacent to the bottom flask 13. When the top and bottom flasks 12, 13, with the 11 coupling plate sandwiched between them, are in a vertical position, the bottom clamping plate 16 has a pressure plane that is oriented horizontally and can be inserted into the filling frame. And the bottom flask, which is attached in 13 planes, provides pressure from this bottom compression assembly 13, defining the boundaries of the molded cavity along with the bottom face of the matching plate 11, bottom flask 13, and the filling frame 15.
