[0002] The injection mold opens after the preform injection is completed, and the preform needs to be cooled outside the mold. Usually, a removal mechanism is used to clamp the picker to pick up the preform located in the core part of the injection mold, and then the picker is used to take out the preform, and the picker is turned over to release the preform.

[0003] The above-mentioned processes of preform injection, removal, extraction and release are all completed by the molding device. During the preform extraction process, the extraction plate needs to move a certain extraction distance toward the picker so that the extraction piece on the extraction plate is located at the extraction position of the preform in the picker, and the preform is extracted from the picker. Therefore, before the preform is injected, the extraction distance of the preform needs to be determined first. Generally, the calibrator is used to calibrate the pickup plate and the extraction plate during the mold trial, and the extraction distance is determined.

[0004] In the existing molding device, the length of the calibrator is fixed. When the length of the bottle mouth part is uncertain or the molded bottle is replaced, the calibrator needs to be replaced or processed according to the length of the bottle mouth part to recalibrate and determine the removal distance.

The free end 12 is provided with a scale 121 arranged along the moving direction of the take-out plate 4, and the scale 121 is used to obtain its scale value after the calibration plate 2 is moved and adjusted. During the mold trial, the calibrator measurement length can be adjusted by adjusting the position of the calibration plate 2 on the free end 12, that is, when the calibrator length is not compatible with the bottle blank removal distance, the calibration plate 2 can be adjusted to adapt, and the bottle blank removal distance can be obtained by the scale value corresponding to the position after the calibration plate 2 is moved and adjusted. There is no need to add a compensation value based on the measured calibrator length, nor is there any need to replace or process the calibrator, so that the removal distance measurement is convenient and efficient.
