The invention discloses an automatic mold opening and closing device for a hollow blow molding machine, belonging to the technical field of plastic processing. The main equipment comprises a base, a guide plate, a fixed plate, a motor, an adjusting screw, a moving assembly, a mold, a plastic thermometer, a guide assembly, a cooling device, a 3D camera and a central control system. The central control system stores temperature values of the plastic parison at various states and a safe temperature drop slope during cooling. By analyzing thermodynamic properties of the plastic parison, it controls the coolant flow rate and temperature of the cooling device, records plastic temperature changes during each demolding cooling process, constructs a function curve, and iteratively calculates the function of plastic temperature versus time during demolding cooling to refine the influence coefficient in the heat release algorithm. This ensures the production quality of plastic products and improves the efficiency of cooling and demolding.
