Problems to be Solved by the blow moulding machine
However, in the conventional blow molding machine, when an attempt is made to shorten the moulding cycle performed through timings t 1 to t 8 , the temperatures of the mold apparatus, the heating cylinder, etc. must be lowered so as to lower the moulding temperature. However, when the moulding temperature is lowered, accuracy in transfer of the pattern of the information surface of the stamper deteriorates.
An object of the present invention is to solve the above-mentioned problems in the conventional blow moulding machines and to provide an blow moulding machine and an blow moulding method which can shorten the moulding cycle without deteriorating accuracy in transfer of a pattern of an information surface of a stamper and without deteriorating optical characteristics.
Means or Solving the Problems
To achieve the above object, a bottle blow moulding machine according to the present invention comprises mold closing processing means for advancing a movable platen so as to perform mold closing; movable-platen-position determination means for determining whether or not the movable platen has reached an blow start position set between a mold opening limit position and a mold closing limit position; and blow processing means for starting an blow step when the movable platen reaches the blow start position.
Effects of the blow moulding machine
The blow moulding machine according to the present invention comprises mold closing processing means for advancing a movable platen so as to perform mold closing; movable-platen-position determination means for determining whether or not the movable platen has reached an blow start position set between a mold opening limit position and a mold closing limit position; and blow processing means for starting an blow step when the movable platen reaches the blow start position.
The temperatures of a mold apparatus, a heating cylinder, etc. are not required to be lowered, and the moulding temperature can be increased sufficiently. Therefore, it becomes possible to prevent deterioration of accuracy in transfer of a pattern of an information surface of a stamper. As a result, distortion, residual stress, and the like are not generated in molded products, whereby the mechanical characteristics of the molded products are improved. In addition, since occurrence of birefringence or the like can be suppressed, the optical characteristics of the molded products can be improved.
