Description
Technical field
What the present invention relates to is a kind of medical packaging container, refers 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 objective of the invention is to seek the method for bottle blowing in a kind of plastic infusion bottle band mould and used mould thereof, 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 present invention, a, preheating are also installed bottle base: the bottle base after preheating in drying tunnel, the temperature adjustment is sent in the bottle blowing mould, the temperature range of preheating, temperature adjustment is the softening point greater than bottle base, fusing point less than bottle base, and the bottleneck that makes bottle base is positioned at the oral area of bottle blowing mould, duckpin is arranged at the bottom at bottle base, and the installing hole of suspension ring is enclosed within on the duckpin; B, seal: place at the oral area of bottle blowing mould again and seal an enclosed cavity that in the bottle blowing mould, forms; C, stretching and extruding: bottle base is elongated to the stretching attitude under the effect of stretching bar, and make the duckpin that is with suspension ring on the bottle base be stretched masthead to the bottle blowing bed die, under the extruding of stretching bar, the duckpin of bottle base bottom is crushed, and suspension ring is riveted on the bottom of bottle base; D, blowing: in the chamber of stretching attitude bottle base, import compressed air again, stretching attitude bottle base is blow molded into the plastic infusion bottle of band suspension ring.
When bottle base is installed, place the bottle blowing bed die in the bottom of two bottle blowing moulds of splitting earlier, have in the inboard of bottle blowing bed die and can hold suspension ring boss annular groove.Projection with the bottleneck position of bottle base embeds in the groove of corresponding position on the bottle blowing mould again.
Have in the inboard central authorities of bottle blowing bed die and to be convenient to the duckpin back that is crushed and to form the groove of discoid manufactured head.One section circular arc is arranged in order to hide the bed die groove on the suspension ring, be blown into groove shapes at the bottom of preventing bottle.When sealing, place sealing ring between bar sealing and stretch.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 used mould of method of bottle blowing in a kind of plastic infusion bottle band mould, 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 rivet root.Oral area placement at the bottle blowing mould is sealed, and sealing ring is arranged in sealing.
Advantage of the present invention is: by injection molding suspension ring being contained on the duckpin of reserving the bottle base bottom, suspension ring through the bottle base band of heating temperature adjustment, directly blow out the plastic infusion bottle that has suspension ring in the die cavity of bottle blowing machine.Thereby save the operation that installs suspension ring additional after the bottle moulding, reduced production site, reduced pollution effectively, improved labor productivity.
