Description
Technical field
The utility model relates to mould locking air pressure swelling mechanism for rotary bottle blowing machine, belongs to the plastics machinery field.
Background technology
When the processing plastic hollow container, can adopt the technology of notes, stretch blow, promptly at first plastic raw materials is annotated and made bottle base, then, again the plastic bottle blank after the heating is sent into stretch blow moulding in the bottle blowing machine to the bottle base heating.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 big expansionary force is arranged, so need clamping mechanism.It is big that existing bottle blowing machine clamping mechanism 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 on the locked mode ring of template; be shaped on 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 big, causes component wear easily, produces die gap behind the component wear; cause bloated mould easily; the bottle qualification rate reduces, and the energy of the big consumption of opening and closing mould power is also big, improves production cost.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, provide a kind of baric systerm to link to each other and move respective outer side edges with mechanical locked mode, the mold clamping force that exists when overcoming the mechanical locked mode of singly depositing is big, easily make component wear produce the defective of die gap, be applicable to rotary bottle blow-moulding machine, when being provided, mechanical lock, die sinking do not have pressure work, the mould locking air pressure swelling mechanism for rotary bottle blowing machine of freedom of motion.
The technical scheme of the utility model mould locking air pressure swelling mechanism for rotary bottle blowing machine is: the frame that comprises a rotation; a left side is installed in frame; right template; a left side; 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 on die cavity in the mould; a left side; right template is by opening; clamping drives; it is characterized in that mould opens the system die behind, convex module is installed in the die, around convex module, be shaped on scrobicular ring; O shape circle is installed in the scrobicular ring; be shaped on passage in the convex module, the air blowing joint is installed on convex module, be shaped on 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 utility model; open system die (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 too big mold clamping force like this when locked mode, when mould locking finished, 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, template do not have to press and restore 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 utility model is opened the system die 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 tensioner.Its described air blowing joint is a screw, and screw is easy for installation.
Description of drawings
Fig. 1 is the utility model mould locking air pressure swelling mechanism for rotary bottle blowing machine structural representation;
Fig. 2 is the A-A schematic cross-section of Fig. 1.
The specific embodiment
The utility model relates to mould locking air pressure swelling mechanism for rotary bottle blowing machine; as Fig. 1; shown in Figure 2; the frame that comprises a rotation; a left side is installed in frame; right template 1; 2; a left side; one of right template is connected to each other by main shaft 3; on a left side; clamping mechanism 15 is installed in the other end of right template; main shaft is fixed in the frame; on a left side; installation mold 4 separately in the right template; 5; be shaped on die cavity 6 in the mould; a left side; right template connects connecting rod 16; 17 and by opening; clamping drives; it is characterized in that mould opens system die (groove) 7 (area of groove is the maximum magnitude that mould allows) behind, convex module 8 is installed in the die 7, around convex module 8, be shaped on scrobicular ring 13; O shape circle 14 is installed in the scrobicular ring 13; be shaped on passage 9 in the convex module 8, air blowing joint 11 is installed on convex module 8, be shaped on gas hole 10 in the air blowing joint 11; gas hole 10 is corresponding with passage 9, and air blowing joint 11 passes template.Open system die (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; when locked mode, do not need too big mold clamping force like this; when mould locking finishes; gas circuit is inflated mould by gas hole and passage, and seal with O ring forms huge mould expanding force between the centre joint of die and convex module; 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; template does not have the reinstatement of pressure, and die sinking is light.Mold clamping force is little during this programme locked mode, and component wear is few, and energy consumes low.Open system die 7 behind at a wherein slit bamboo or chopped wood mould of two slit bamboo or chopped wood moulds 4,5, form the stable combination of inner structure with another slit bamboo or chopped wood mould air pressure tensioner by a slit bamboo or chopped wood mould.Its described air blowing joint 11 is screws, and screw is easy for installation.
