Abstract | The invention discloses an automatic control method of mold temperature in a rotational molding process, which is characterized in that an infrared temperature sensor is used for monitoring the surface temperature of a rotational molding mold, an electric actuation mechanism which is installed on a gas pipeline is used for controlling the gas flow, so that the rotational molding temperature can be automatically controlled. Through a servo motor which is installed on a rotational molding machine, a support which is provided with the infrared temperature sensor is driven by a lead screw to move back and forth, the temperature of the rotational molding mold in the axial direction can be measured, a temperature signal is inputted to an industrial control computer after being processed, a temperature chromaticity of the rotational molding mold body and a two-dimensional temperature distribution histogram are generated, a temperature difference signal is converted to a corresponding flow signal through a signal pro |
