Molding support device for injection molding machine

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;
• a data processing unit 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;
• and
• a molding machine controller having an output processing function unit which displays the control temperature on a display,
• wherein the basic data input unit has a function of inputting basic data including at least molding condition data relating to molding conditions and screw data relating to the form of the screw,
• wherein the screw data includes data relating to the material type on the screw surface, and
• wherein the data processing unit has a decomposition rate formula data for calculating the resin decomposition rate of the screw surface during molding is set in the Operation expression data setting unit based on the basic data, and the calculation processing function unit has the decomposition rate calculation processing function unit for calculating an estimated resin decomposition rate based on the basic data and a Decomposition rate operation expression data.
