Abstract: A mold manufacturing system includes a conveyer circuit upon which a multiple of molds transit a closed loop and repetitively pass through a central booth. The system is separated into Zones in which a particular mold operation is performed. Each of a multiple of applying operations are performed within the central booth which contains a common exhaust plenum. Application of exceedingly expensive environmental emission control devices is at least partially mitigated. Consolidation of multiple spray operations into a few spray Zones also advantageously simplifies the control of chemical and ambient variables which improves production efficiencies and reduces operator dependency.

Abstract: An object is to reduce mutual interference between a plurality of sets of molds coupled to a common frame stand to improve the processing accuracy. A plurality of sets (e.g. two sets) of molds are driven by servo motors (6a, 6b). The servo motors (6a, 6b) are individually controlled by servo amplifiers (8a, 8b), respectively. A control portion in the servo amplifier (8a) calculates a current (I) so that the measured value (X) of the rotating position of the servo motor (6a) follows a directing value (X0) sent from a CPU through a pulse generator (9). A torque detecting/limiting portion (25) limits the calculated current (I) so that a limit value of the torque sent from the CPU through a DA converter (12) is not exceeded and sends it to the servo motor (6a) through a current amplifier (26). When the torque of the servo motor (6a) reaches the limit value after the molds come in contact, the directing value (X0) is rapidly advanced in the mold-losing direction.
