Description
Technical field
The present invention relates to mould locking air pressure swelling mechanism for rotary bottle blowing machine, belong to the plastics machinery field.
Background technology
When the processing plastic hollow container, can adopt the technique of notes, stretch blow, namely at first plastic raw materials is annotated and made bottle base, then to bottle parison heating, again the plastic bottle blank after the heating is sent into stretch blow moulding in the bottle blowing machine.The kind of existing blower for plastic bottle is a lot, and is different with folding mould mode according to the structure of template, can be divided into translational opening-closing template and jaw type folding template.Jaw type folding template is to rely on connecting rod to drive left and right two templates to rotate and open, thus two templates wherein one be connected to each other, and the other end is done to open or closing motion, when the drawing and blowing plastic bottle, very large expansionary force is arranged, so clamping mechanism need to be arranged.It is large that existing clamping mechanism for bottle-blowing machine exists volume; shortcoming more than taking up room is not suitable on the rotary bottle blow-moulding machine, so the applicant had once applied for Chinese patent ZL200520015537.1; this clamping mechanism is shaped with the locked mode ring of template; be shaped with the locked mode hole in the locked mode ring, in the locked mode ring lifting arm be installed, lifting arm drives the locked mode pin through cross bar; the locked mode pin matches with the locked mode hole of locked mode ring; its advantage is that volume is little, occupies little space, and is applicable on the rotary bottle blow-moulding machine.But the shortcoming that this clamping mechanism exists is that the opening and closing mould power that needs when locked mode, the demoulding is very large, causes easily component wear, produces die gap behind the component wear; cause easily swollen mould; the bottle qualification rate reduces, and the energy of the large consumption of opening and closing mould power is also large, improves production cost.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, provide a kind of baric systerm to link to each other with mechanical locked mode and move respective outer side edges, the mold clamping force that exists when overcoming the mechanical locked mode of singly depositing is large, easily make component wear produce the defective of die gap, be applicable to rotary bottle blow-moulding machine, with no pressure work when mechanical lock, die sinking are provided, the mould locking air pressure swelling mechanism for rotary bottle blowing machine of freedom of motion.
The technical scheme of mould locking air pressure swelling mechanism for rotary bottle blowing machine of the present invention is: the frame that comprises a rotation; in frame, install left; right template; left; one of right template is connected to each other by main shaft; on a left side; clamping mechanism is installed in the other end of right template; main shaft is fixed in the frame; on a left side; installation mold separately in the right template; be shaped with die cavity in the mould; left; right template is by opening; clamping drives; it is characterized in that mould opens die processed behind, convex module is installed in the die, around convex module, be shaped with scrobicular ring; O shape circle is installed in the scrobicular ring; be shaped with passage in the convex module, at convex module the air blowing joint be installed, be shaped with gas hole in the air blowing joint; gas hole is corresponding with passage, and the air blowing joint passes template.
Mould locking air pressure swelling mechanism for rotary bottle blowing machine of the present invention; open die processed (groove) behind at mould; convex module is installed in the die; O shape circle is installed around the convex module; passage in the convex module is corresponding with the gas hole in the air blowing joint; do not need so too large mold clamping force when locked mode, when mould locking was complete, gas circuit was inflated mould by gas hole and passage; seal with O ring; between the centre joint of die and convex module, form huge mould expanding force, a whole set of clamping mechanism can not become flexible, guarantee the qualification rate of moulding bottle; after the blower finishes; the air pressure of releasing, the template with no pressure restores to the original state, and die sinking is light.Mold clamping force is little during this programme locked mode, and component wear is few, and energy consumes low.
Mould locking air pressure swelling mechanism for rotary bottle blowing machine of the present invention is opened die processed behind at a wherein slit bamboo or chopped wood mould of two slit bamboo or chopped wood moulds, and convex module is installed in the die, forms the stable combination of inner structure by a slit bamboo or chopped wood mould with another slit bamboo or chopped wood mould air pressure expansion.Its described air blowing joint is screw, and screw is easy for installation.
