Molding machine, control apparatus, and molding apparatus

A molding machine, comprising:

• a cylinder;
• a nozzle, connected to a front end of the cylinder;
• at least one heater, externally attached to a cylindrical wall of the cylinder;
• a pressurization portion, applying pressure to resin for releasing the resin filled in the cylinder to the outside of the cylinder;
• and
• an ultrasonic viscosity sensor, penetrating through the cylindrical wall of the cylinder and located directly adjacent to the at least one heater, the ultrasonic viscosity sensor comprising a base, an oscillator embedded in the base, and an ultrasonic vibration portion installed on one end of the oscillator and in contact with the resin filled in the cylinder, wherein the ultrasonic vibration portion protrudes from the base into a gap filled with the resin in the cylinder, such that the ultrasonic vibration portion is physically and directly in contact with the resin,
• wherein a front end of the pressurization portion does not intersect with a vertical projection of the ultrasonic vibration portion of the ultrasonic viscosity sensor that is in contact with the resin filled in the cylinder.
