Mote molding machine

A mote molding machine for producing motes in a molding cycle, the molding cycle having a compression phase and an extraction phase;

• the molding machine comprising:
• a molding chamber defining a molding cavity, the molding chamber having a front end and a rear end opposite the front end;
• a front plate movable between a first position and a second position,
• wherein in the first position, the front plate closes off the front end, and
• wherein in the second position, the front plate does not close off the molding chamber but the front end allows extraction of a molded object from the molding chamber through the front end;
• a rear plate located opposite the front plate, the rear plate movable between a third position and a fourth position,
• wherein in the third position, the rear plate closes off the rear end,
• wherein in the fourth position, the rear plate pushes the molded object from the molding chamber through the front end;
• a first shifting system for moving the front plate between the first position and the second position;
• and
• a second shifting system for moving the rear plate between the third position and the fourth position;
• wherein the first shifting system comprises a first electric motor for moving the first plate in the compression phase and the extraction phase;
• wherein the second shifting system comprises a second electric motor for moving the rear plate in the extraction phase and the compression phase, and
• wherein the first electric motor shifts the front plate toward the molding cavity in the compression phase and the second electric motor shifts the rear plate toward the molding cavity in the compression phase;
• wherein the first electric motor or the second electric motor is associated with a gear mechanism with a first state and a second state and with an output operating at a higher speed in the second state than in the first state, while a speed of the first electric motor or a speed of the second electric motor is substantially the same, the first state corresponding to the compression phase and the second state corresponding to the extraction phase.

• a second shifting system for moving the rear plate between the third position and the fourth position;
• wherein the first shifting system comprises a first electric motor for moving the first plate in the compression phase toward the molding chamber and in the extraction phase;
• wherein the second shifting system comprises a second electric motor for moving the rear plate in the extraction phase and the compression phase;
• wherein the first electric motor and/or the second electric motor is a servomotor;
• and
• wherein a speed of movement of the front plate and the rear plate during the compression phase is slower than a speed of movement of the front plate and the rear plate during the extraction phase.
