ABSTRACT:
A rotary plastic molding apparatus having internal packing space is featured. A nozzle is divided into channels equal to the number of casting device disks. Grooves are disposed in casting disks for supplying the melt. The grooves are displaced relative to each other and slots are provided between them to introduce packing lintels. The mold is divided into sections. In each section, an accumulator and sockets for molding articles are provided. The components communicate among themselves and can be oriented at definite angles. The accumulator is disposed before the molds. Holes are provided to supply the melt from the accumulator to the molds. Certain holes can be closed to get a certain article drawing. The transition section of the accumulator is divided into sections for uniform division of the melt. The number of sections is equal to the number of sockets. Centers of sockets are connected with the mold inner space by means of holes for casting articles with lugs or for supplying additional melt component to the socket.
