1. A molding support device for an injection molding machine which injects and fills a metal mold with a plasticized molten resin by a screw and molds the molten resin, comprising:
a controller configured to control the temperature of a material supplier which supplies a resin material to an inside of a heating cylinder;
a basic data input unit which can input at least a resin material type;
a Controlled temperature data table in which an optimum control temperature by a temperature control unit is set for each resin material type; and
a data processing unit associated with the controller having a temperature setting processing unit which reads the optimum control temperature corresponding to the resin material type input from the basic data input unit at least when molding conditions are set, thereby setting a control temperature of the temperature control unit,
wherein the controller has an output processing function unit which displays the control temperature on a display, and
wherein an upper limit value of the optimum control temperature is set in the Controlled temperature data table associated with the controller, and
wherein the controller is further configured to control the temperature control unit to maintain the molten state of the resin in the heating cylinder in an optimum state.
