Description
Technical Field
The invention relates to the field of bottle blowing machines, in particular to a method for generating a curve track of a mold opening and closing guide rail of a bottle blowing machine.
Background
The bottle blowing machine is a machine capable of blowing plastic particles (softened into liquid) or prepared bottle blanks into bottles by a certain technological means. As shown in fig. 1, the bottle blowing machine comprises an opening and closing die guide rail, a die carrier, a left die and a right die. The mold opening and closing guide rail and the mold frame can rotate around a rotation center O, the left mold and the right mold are hinged together through O3 on the mold frame and used for grabbing bottle blanks and manufacturing bottles, the connecting rods O1O2 and O1O6 are fixedly connected together and rotate around an O1 point on the mold frame, the lengths of the connecting rods O2O5 and O2O4 are equal, one end of the O2O5 is hinged with the O5, the other end of the O2O5 is hinged with the O2O1, and similarly, one end of the O2O4 is hinged with the O4, and the other end of the O2O1 is hinged. The bottle blowing machine controls the opening and closing angle of the left die and the right die by controlling the O6 on the opening and closing die guide rail.
The inventor finds that in actual work, in some cases, the left die and the right die cannot accurately grab the bottle blank or grab the offset in actual operation of the bottle blowing machine, so that the produced bottle has high defective rate.
In order to reduce the defective rate, the inventor originally believes that the position deviation of the bottle blank placement causes the mold frame to capture the bottle blank inaccurately, so the position of the bottle blank is adjusted correspondingly, however, the defective rate of the bottle is still high. Through further analysis, the inventor believes that, because the mold opening and closing guide rail arranged between the rotation center and the mold frame on the bottle blowing machine is in a cam shape, the center dividing line of the left mold and the right mold and the connecting line from the rotation center O to the mold frame O3 have deviation (i.e. OO3 and O2O3 are not collinear) under certain angles, and when the bottle blowing machine designs the mold opening and closing guide rail curve, the default is that the center dividing line of the left mold and the right mold is overlapped with the connecting line from the rotation center to the mold frame center, and the mold frame cannot catch the bottle blank at certain angles because the default ignores the deviation between the center dividing line and the connecting line caused by the cam. Therefore, how to accurately obtain the curve track of the mold opening and closing guide rail of the mold frame so as to reduce the inferior product rate becomes a technical problem to be solved urgently.
