Description

The device of bottle blowing in the plastic infusion bottle band mould

Technical field

The utility model relates to a kind of medical packaging container, refer in particular to a kind of plastic infusion bottle and production method thereof with the band suspension ring of annotating the production of stretch blow method.

Background technology

Conventional production methods with the plastic infusion bottle of injection stretch blow moulding production is: bottle is by the base blow molding of bottle blowing engine room, suspension ring are by injection machine injection moulding, with the method for assembling suspension ring are contained in the bottom of bottle then, with methods such as ultrasonic wave, electrical heating or flame heat bottle and suspension ring are bound up again, form an integral body, production process is many, is easy to generate pollution.

Summary of the invention

The purpose of this utility model is to seek the device of bottle blowing in a kind of plastic infusion bottle band mould, by injection molding suspension ring being contained on the duckpin of reserving the bottle base bottom, bottle base band through the heating temperature adjustment suspension ring, directly blows out the plastic infusion bottle that has suspension ring in the die cavity of bottle blowing machine.Save the back manufacturing procedure of bottle, reduced production site, reduced pollution effectively, improved labor productivity.

According to design provided by the utility model, the bottle blowing bed die is placed in bottom at two bottle blowing moulds of splitting, groove in that the oral area of bottle blowing mould has the projection that allows the bottle base oral area to embed is characterized in that the annular groove that can hold suspension ring is arranged in the inboard of bottle blowing bed die.

After having the duckpin of being convenient to the bottle base bottom to be crushed, the inboard central authorities of bottle blowing bed die form the groove of discoid manufactured head.Oral area placement at the bottle blowing mould is sealed, and sealing ring is arranged in sealing.Bottom at two bottle blowing moulds of splitting is provided with annular groove, can embed the annular projection of this annular groove the corresponding position setting of bottle blowing bed die.

The utility model has the advantages that: by injection molding suspension ring being contained on the duckpin of reserving the bottle base bottom, suspension ring, in the die cavity of bottle blowing machine, directly blow out the plastic infusion bottle that has suspension ring through the bottle base band of heating temperature adjustment.Thereby save the operation that installs suspension ring additional after the bottle moulding, reduced production site, reduced pollution effectively, improved labor productivity.

The specific embodiment

The production method of bottle blowing is as follows in the plastic infusion bottle band mould:

A, preheating are also installed bottle base: place bottle blowing bed die 5 in the bottom of two bottle blowing moulds of splitting 6,8 earlier, the annular groove 19 that can hold boss on the suspension ring 3 is arranged in the inboard of bottle blowing bed die 5; Bottle base is through the preheating temperature adjustment, the temperature range of preheating, temperature adjustment is the softening point greater than bottle base 1, fusing point less than bottle base 1, heating-up temperature is controlled temperature by the electronic pressure controller adjustment by changing voltage method, in the bottom of bottle base 1 duckpin 2 is arranged, the installing hole 15 of suspension ring 3 is enclosed within on the duckpin 2, place bottle base 1 and suspension ring 3 in the bottle blowing mould, and the projection 16 at the bottleneck position of bottle base 1 is embedded in the groove 21 of corresponding position on the bottle blowing mould, the bottleneck of bottle base 1 is positioned at the oral area of bottle blowing mould;

B, seal: place at the oral area of bottle blowing mould again and seal 11, an enclosed cavity that in the bottle blowing mould, forms; And seal 11 and 10 on stretching bar place sealing ring 12;

C, stretching and extruding: the bottle base 1 through temperature adjustment is elongated to stretching attitude 9 under the effect of stretching bar 10, and make the duckpin 2 that is with suspension ring 3 on the bottle base 1 be stretched bar 10 tops to bottle blowing bed die 5, under the extruding of stretching bar 10, the duckpin 2 of bottle base 1 bottom is crushed, and suspension ring 3 is riveted on the bottom of bottle base 1;

D, blowing: in the chamber of stretching attitude bottle base 9, import compressed air again, stretching attitude bottle base 9 is blow molded into the plastic infusion bottle 13 of band suspension ring 3.

One section circular arc 14 is arranged in order to hide the bed die groove on the suspension ring 3, be blown into groove shapes at the bottom of preventing bottle.Bottom at two bottle blowing moulds of splitting 6,8 is provided with annular groove 17, can embed the annular projection 18 of this annular groove 17 the corresponding position setting of bottle blowing bed die 5.Have in the inboard central authorities of bottle blowing bed die 5 and to be convenient to duckpin 2 back that is crushed and to form the groove 20 of discoid manufactured head.

The used mould of the method for bottle blowing as shown in the figure in this plastic infusion bottle band mould: bottle blowing bed die 5 is placed in the bottom at two bottle blowing moulds of splitting 6,8, the groove 21 that projection 16 embeddings that allow bottle base 1 oral area are arranged at the oral area of bottle blowing mould 6,8, utilize this groove 21 bottle base 1 can be fixed with projection 16, in order to avoid when pushing and blow, bottle base is moved, and has influence on normal manufacture process.Have in the inboard of bottle blowing bed die 5 and can hold boss annular groove 19 on the suspension ring 3, have the duckpin 2 of the being convenient to bottle base 1 bottom back that is crushed to form the groove 20 of discoid manufactured head in the inboard central authorities of bottle blowing bed die 5.Place at the oral area of bottle blowing mould and to seal 11, sealing ring 12 is arranged sealing in 11.
