The present application describes a modular unit for injection-compression molding (1). The modular unit for injection-compression molding (1) is arranged between the movable platen of the injection machine (21) and the stationary platen of the injection machine (22), in particular in the half-mold bearing face resulting from the division thereof by the opening joint. This modular unit for injection-compression molding (1) allows a substantial reduction of energy spent by reduction of inertial masses involved. The present application describes a modular unit for injection-compression molding (1) to be used in the production of pieces by injection being installed on any thermoplastic molding process.

A control device for an injection molding machine has a first operation condition setup unit for setting an operation condition for a setting operation, a conversion table for storing in pairs an operation condition for the setting operation and an operation condition for a pull operation, a second operation condition setup unit for setting, by reference to the conversion table, an operation condition for the pull operation in correspondence to the operation condition for the setting operation set by the first operation condition setup unit, and a driving command generation unit for generating driving commands which drive the injection molding machine to perform the setting operation and the pull operation in accordance with the operation conditions set by the first operation condition setup unit and the second operation condition setup unit.
