[origin: US4637558A] PCT No. PCT/DE84/00247 Sec. 371 Date Jun. 27, 1985 Sec. 102(e) Date Jun. 27, 1985 PCT Filed Nov. 17, 1984 PCT Pub. No. WO85/02137 PCT Pub. Date May 23, 1985.The decoring apparatus (1) consists of a portal-shaped support frame (2), at each of the vertical posts (4) and supports (5) on which a bracket (7) is provided. From each of these, via a swinging arm (9), a carrying unit (11) is suspended which is able to swing freely like a pendulum. Said carrying unit has two longitudinal arms (14,15) on which two vibrators (23) and two buffer bars (20) or an impact plate (19), as the case may be, are provided, whereby between the latter there is a casting receiving opening (16), and on the rear side of which several support bars (17) are provided. A casting (a) is loosely set into the receiving opening (16), and the carrying unit (11) is put into motion by vibrators (23). Since said vibrations induce the loose casting (a) to vibrate as well, the latter is quickly and freely moved back and forth between the impact plate (19) and the buffer bars (20) within a defined clearance (c), whereby the casting knocks against them in turn. By this, and due to vibrations induced into the casting (a), the sand cores contained therein disintegrate to sand and flows out at the bottom.
