Molding Condition Diagnostic Device

A molding condition diagnostic device provided in a molding machine to determine whether a molding condition setting value is appropriate or not and inform an operator of a result of the determination, the molding machine having:

• a molding machine body which is provided with a mold opening/closing device and an injection device injecting a molding material into a cavity of a closed mold so that the molding machine body can repeat a predetermined molding cycle including a plurality of steps to mold a predetermined molded product;
• a molding condition setting unit which is operated by the operator to set a molding condition for the molding machine body;
• a control unit which controls driving of the molding machine body based on a molding condition reference value determined by specifications of the molding machine body and the molding condition setting value set in the molding condition setting unit;
• and
• a measurement unit which is provided in a predetermined region of the molding machine body to thereby measure and output a predetermined physical amount of the region where the measurement unit is provided;
• the molding condition diagnostic device comprising:
• an input portion which receives a measured value outputted from the measurement unit and the molding condition setting value set in the molding condition setting unit;
• a comparison portion which compares the measured value and the molding condition setting value both received by the input portion with each other;
• a storage portion in which a criterion for determining that the molding condition setting value is inappropriate is stored;
• a determination portion which determines whether a comparison result of the comparison portion satisfies the criterion stored in the storage portion or not;
• and a display portion which displays a specific determination message according to the measured value and the molding condition setting value compared with each other, when the determination portion determines that the comparison result of the comparison portion satisfies the criterion stored in the storage portion;
• wherein:
• the display portion is configured to be able to display various display image data selected by the operator in various display modes so that the determination message can be displayed on a display screen of the display portion when display of the determination message is selected by the operator.
