PET bottle preform blow molding heating device and method

The invention relates to the field of blow molding processing equipment, in particular to a PET bottle preform blow molding heating device and method. The PET bottle preform blow molding heating device comprises a mounting bottom frame, a moving mechanism and the like; the mounting chassis is connected with a moving mechanism. After the bottle is subjected to heating blow molding treatment in the mold, the moving mechanism drives the right mold shell and the left mold shell to conduct separation work at the initial stage, the local cooling mechanism firstly conducts cooling treatment on a preset structure area of the bottle in a concentrated mode, and the cooling shaping speed of the connecting position of the bottle and the preset structure is increased; and the separation time of the two molds is later than that of the right mold shell and the left mold shell, so that the cooling demolding time of a bottle formed by blow molding between the right mold shell and the left mold shell is prolonged.
