Embodiment 1
[0028] Please see Fig. 1 and in conjunction with Fig. 5, the inner and outer mold connecting plates 2, 1 of the bottle-holding device are respectively connected with the inner and outer templates 45, 46 of the mold frame 42 of the automatic blow molding machine (see Fig. 4). This connection can be realized with screws, it can also be welded, and so on. In this way, the inner and outer mold connecting plates 2,1 can be opened and closed with the opening and closing of the inner and outer templates 45,46 of the mold frame 42 of the automatic blow molding machine, and a pair of bottle half molds 20,21 face each other and can Dismountably be arranged on the inner side of a pair of inner and outer mold connecting plates 2,1, when the shape and specifications of the bottle 43 etc. change, then the bottle half molds 20,21 also change accordingly. The bottle half mold 20,21 illustrated in Fig. 1 is only aimed at a certain kind of bottle 43 of the size shown in Fig. 5 and Fig. 8, so th...
Embodiment 2
[0032] Please refer to Fig. 2 and Fig. 6, the structure of this embodiment is the expansion of the structure disclosed in Embodiment 1, this expansion is mainly reflected in the change of the moving seat 13 and the central gear 30 is set at the lower end of the central shaft 4, A hollow seat cavity 28 is formed in the moving seat 13, and by setting the corresponding parts to be mentioned below, it becomes a structural form exactly like a gear box, and the rest are still the same as in Embodiment 1. There are also two groups of rotary cutter shafts 36 belonging to the flash cutting device on the mobile seat 13, and each group of rotary cutter shafts 36 has at least one pair, and a rotary cutter bar 15 is affixed to the bottom of each rotary cutter shaft 36. In this case, the lower end of the central shaft 4 may or may not be provided with the rotary cutter bar 15, and it is necessary to add a central gear 30. Two groups of rotary knife shafts 36 are shown in the figure, each gr...
Embodiment 3
[0034] Please refer to FIG. 3 and FIG. 7 , in this embodiment, the central shaft driving mechanism for driving the central shaft 4 to rotate is changed to adopt a stepping motor 39 , and the rest are the same as in Embodiment 1 or 2. The stepping motor 39 is located on or claims to be seated on the moving seat 13 through a bracket 37, and the output shaft of the stepping motor 39 is connected with the central shaft 4 through a coupling 38, and the central shaft 4 is still supported by a pair of bearings 6,3. Realize being pivotally placed on the mobile seat 13. Compared with Embodiment 1 and Embodiment 2, the structure of this embodiment is simpler in structure and cheaper in cost.
[0035] FIG. 8 schematically shows the situation after the bottle finish 44 of the bottle 43 is cut off through the implementation of Examples 1, 2, and 3.
[0036] The applicant selected Figures 2 and 6 and combined with Figure 4 to describe the process of cutting off the flash 44 of the bottle m...
