Description
Technical field
The utility model is related to liquid packing device field more particularly to a kind of bottle blowing machine and its left and right mold lock locking mechanisms.
Background technology
The bed die of existing rotary big mould bases bottle blowing machine moves up and down the action with left and right half module respectively by cam tracks
Control, when mould bases is in revolution main body rotary course, there is the used action of following company：It is put into bottle base, bed die rises, and left and right mould closes
Mould, blown bottle, right mould frame open, and bed die declines, and bottle takes out, these actuation cycles make production be carried out continuously.
Swing arm 8 and swing rod 10 are consolidated by balance staff 11 in existing rotary big mould bases bottle blowing machine as shown in Figure 1 and Figure 2, are put
Bar is to be connected with to make by being articulated with the connecting rod 9 of left mould 3, right mould 2 to can control left mould 3,2 opening and closing movement of right mould, swing arm other end
The open mold roller 7 that swing arm is swung, open mold roller 7 are driven by open mold cam tracks (not shown), bed die bearing 4
Bottom end is also connected with bed die roller 5, and bed die roller 5 controls its up and down action by bed die cam tracks 6.
Existing rotary bottle blow-moulding machine is primarily present defect below：1, a bed die cam tracks control several die cavitys
Bed die, the height of bed die are not easy to be adjusted to consistent height.2, bed die cam tracks are curve non-close, are filled by various making
