Abstract: A molding apparatus is disclosed which includes a first support having spaced apart vertical posts, and a first set of mold halves positioned between the vertical posts. A second support is provided having positioned thereon a second set of mold halves. A clamp bar is positioned on the vertical posts adjacent the second support so as to extend across the mold halves of the second set of mold halves. A grip member secured to the first support is movable between an engage and disengage position, wherein in the engage position a clamp engages the grip member and the clamp bar so as to drive the respective sets of mold halves into sealing contact with each other, so as to form two mold cavities. In the disengage position, the grip member is clear of the clamp so as to permit the clamp to also act as a device to separate the supports when the molding process is over. Methods of using this equipment in an automated rotational molding process are also disclosed.

Abstract: A strip casting device (2) has a casting container (14) from which through a casting gap (15) two different masses (12, 13) of a material flowable with the addition of heat are poured out as a strip (3) onto a cooling device (4). The second mass (13) is at the same time ejected by way of injection nozzles (21, 22) into the region of the casting gap (15) into the casting flow of the first mass (12). The injection nozzles are preferably movable in various directions.

Abstract: A rotatable turret block is mounted on an index molding machine. The turret block includes at least one mold core for forming molded articles thereon at least one face of the rotatable turret block. The molded articles are transferred from the mold cores to spaced track members for retention and cooling thereon, and the cooled molded articles removed from the track members.

Abstract: The present invention includes a mold apparatus for facilitating replacement of rotatable molds therein. First and second frames are provided forming a plurality of mold cells and each mold includes an upper and a lower mold section. The upper mold section is removably coupled to the upper frame, while the lower mold section is removably coupled to the lower frame. Using this arrangement, a mold may be removed by detaching all connections between it and the frames, while maintaining the frames closed. Similarly, a mold may be inserted into a mold cell and connected to the frames while maintaining the frames closed. The removal and insertion operations may be performed radially or axially, depending on frame configuration.
