Description

The blower for plastic bottle that a kind of hydraulic strip is cranked arm

Technical field

This utility model is related to a kind of blower for plastic bottle, more particularly to the blower for plastic bottle that a kind of hydraulic strip is cranked arm.

Background technology

The course of work of bottle blowing machine is usually that plastic raw materialss are extruded blank by extruder, then will extrude blank and be put into and blow Blow molding in molding machine, existing clamping system mostly are pneumatic matched moulds, and be a matched moulds in place, the die cavity of split is promoted And be docking together and carry out blow moulding process, and for blow moulding process, blow gas pressure is bigger, product and die cavity Laminating degree is better, and the quality of product is naturally higher, but while the bad mold joint of die cavity is understood in air pressure due to there is gap The lower phenomenon for producing swollen mould of effect, affects molding effect, while can produce material side at bad mold joint, air pressure is bigger, expects the size on side It is bigger, more cut tough and remove, so this has occurred as soon as the phenomenon of contradiction：On the one hand, for improve product quality, need to add Pressure；On the other hand, in order to reduce the size on material side, pressure again can not be excessive.

Utility model content

The purpose of this utility model be avoid the deficiencies in the prior art in place of, there is provided the plastics that a kind of hydraulic strip is cranked arm blow Bottle machine, so as to effectively solving the shortcomings of the prior art.

For achieving the above object, the technical scheme that this utility model is taken is；The blower for plastic bottle that a kind of hydraulic strip is cranked arm, Including support body, the support body is provided with sliding sleeve, and horizontally slidable in sliding sleeve to be provided with lead column, lead column left end is installed with frame Plate, lead column middle slip are provided with left mould frame, are installed with left mould chamber on the left mould frame；The lead column right-hand member is installed with right mould Frame, right mould frame are provided with the right mould chamber being adapted with left mould chamber；Air blowing pressue device is additionally provided with the support body, and the frame plate is right Side is installed with the first contiguous block, is installed with the second contiguous block on the left of the left mould frame；First contiguous block passes through the first pivot It is articulated with L-type first connecting rod；Second contiguous block is articulated with second connecting rod by the second pivot；The L-type head rod Corner and the second connecting rod pivot joint；Drive rod pivot joint at the quarter butt of the L-type first connecting rod with driving means, the drive Dynamic device is fixed on a mounting board, is hinged with four third connecting rods on the installing plate, and four third connecting rods are respectively with the The end of one pivot and the second pivot is hinged；The first tooth bar is installed with the right side of the frame plate, is installed with the second tooth on the left of left mould frame Bar, is articulated with gear on the support body, the upper and lower of gear is meshed with the first tooth bar and the second tooth bar respectively.

Further, the driving means are pneumohydraulic pressure-cylinder.

Further, it is described to be hinged as ball-joint.

Further, the third connecting rod that the first pivot both ends are respectively articulated with is parallel, the second pivot both ends The third connecting rod being respectively articulated with is parallel.

Above-mentioned technical proposal of the present utility model has the advantages that；This utility model is using the connection side for cranking arm Formula, it is possible to achieve the process of secondary mould closing, during first time matched moulds, the pressure that driving means are provided is relatively small, blows Gas pressue device provides relatively small pressure, blank is tentatively fitted on mould intracavity wall, at basic forming, and bad mold joint Tablet it is less, it is easy to clear up；During second matched moulds, driving means and air blowing pressue device are provided which big pressure Power, enables being fitted on mould intracavity wall for blank uniform close, and due to during first time matched moulds tablet formed, Although secondary mould closing pressure is very big, the size of tablet will not be increased substantially, be easy to excision, alleviate the negative of operator Load, and product is non-leakage, high pressure；During secondary mould closing, driving means provide big pressure, coordinate knot of cranking arm Structure, makes die cavity that the phenomenon of swollen mould will not occur；Using pneumohydraulic pressure-cylinder, pumping plant and motor is eliminated, save the electricity charge and equipment Expense, realizes the purpose of energy-conservation, while without the need for arranging hydraulic valve again, it is to avoid hydraulic valve damages the inconvenience for bringing, it is ensured that set Standby normal operation；This utility model had both realized big pressure production, it is ensured that the quality of product, realized generation again little Tablet, is convenient to clean.
