MOLDING MACHINE Russian patent published in 2005 - IPC

FIELD: chemical industry; machines for molding of plastic items.

SUBSTANCE: the invention presents a molding machine and is dealt with the field of molding of plastic items, in particular, with machines for thermo-molding. The molding machine contains a guiding stand, a shaping element and the gear of its motion, a heater of a molded section of a thermoplastic film, a pressing frame for fixing a molded section of the thermoplastic film, a gear of the pressing frame movement, a vacuum system for covering of the form-shaping element with a thermoplastic film, a means of cooling of a thermoplastic film molded section and a thermoplastic film periodic transportation gear with grabs and the means to position the grabs. At that the means to position the grabs are made in the form of a drive having an engine, a unit to control duration of engine braking the gear of periodic transportation, a transmission, gages of a final position and limiters of the thermoplastic film molded section transportation. The Gages of the final position are located with a capability to transmit a signal about a position of the thermoplastic film molded section for a distance up to the limiters of transportation equal to the value exceeding the path of braking at least by the value of a shift within the limits of a clearance of transmission. So the invention allows to create a reliable means for thermo-molding of items from the roll thermoplastic film.

EFFECT: the invention ensures creation of a reliable means for thermo-molding of items from the roll thermoplastic film.
