ABSTRACT:
A thermoforming machine having a plurality of stations arranged in a circle, i.e., a charging station for insertion of a plate or sheet of thermoplastic material, a heating station, a forming station and a discharging station for the finished part (which discharging station may be the same as the charging station) and a like plurality of clamping frames for the thermoplastic material which frames can be pivoted from station to station, and with the forming station being provided with a height adjustable mold table for accommodating a deep drawing mold and a height adjustable blow box. To raise and lower the mold table, a pair of hydraulic cylinders are symetrically arranged on the respective sides of the mold table with the cylinders being essentially vertical in the interior of the blow box. Each of the cylinders and its associated piston rod is connected between a stationary support plate for the mold table and the mold table.
