ABSTRACT:
A machine for the manufacture of hollow plastic pieces with several axes located at angles to each other in a three dimensional sense, which includes mold halves for forming a mold chamber, wherein the mold halves are supported so that at least one of them is moved into and out of contact with the other, at an angle between 40.degree. and 60.degree., and preferably about 45.degree. relative to the horizontal, the extruder, including the extruder head for forming heated preform blanks to be inserted in the mold, being supported by four superposed tables, the upper table being carried on rails on the next lower table so that it can move horizontally in first horizontal directions, the second table being supported by rails on the third lower table so that it can also move horizontally relative thereto, but at right angles to the movement of the first table, the third table being turnable within limits about a swivel or hinge mounted on the lowermost table which has a mechanism for raising and lowering all of the tables simultaneously, whereby the heated preform blanks or hollow tubes being extruded from the extruder head can be positioned for insertion between the mold halves at any desired disposition.
