Description
Technical field
The present invention relates to a kind of processing molding method of plastic products and devices, more particularly, to a kind of pipe embryo of plastic bottle
Forming method and pipe embryo mould.
Background technique
With the development with rapid changepl. never-ending changes and improvements of plastics and its product, plastic processing production is developing progressively a huge industry
Cluster, almost all trades and professions are all utilizing plastic products.With the continuous development of plastic part demand, the method for plastic processing also exists
It is continuous to update.Injection molding is one of main plastics processing mode；So-called injection molding is exactly by thermoplasticity
Plastics (PC, PE, PS, PP, PVC, PA, ABS etc.) in barrel through external heat and screw rod rotational shear heat effect plasticizing after, with one
Fixed injection pressure injection has in the mold of cooling device, and the plastics processing of all types of plastic product is obtained after rapid cooling
Method.But simple injection molding, for some exigent, such as beverage bottle, water bottle or medicine bottle etc. are molded into using conventional
Type is difficult to reach requirement, as the mainstream processing technology of plastic hollow vessel, " note stretch blow " and " multi-layer co-extruded " technology increasingly at
For people's focus of attention.So-called " note stretch blow " is that the molten plastic of injector injection is injected injection mold, by sharply cold
But mold it is transparent have die bed base, external heat in parison then will be had into die bed after reaching certain temperature in another station
Base extends certain ratio, is re-filled with compressed air, obtains required hollow product.
Such processing method is selected, smooth bottleneck can not only be generated, and entire bottle-type can be strengthened, bottle wall is enabled to subtract
Thin, each bottle weight is the same, saves the material of bottle." note stretch blow " has become important in polymer processing field now
A ring, have many advantages, such as improve Mechanical Properties of Products, barrier properties for gases, have a wide range of application, be that other bottle blowing machines cannot substitute
A kind of forming technique.In recent years, one-step injection stretch blow moulding shows booming trend, which refers in an equipment

It is more, volume is larger, structure design it is more complex, manufacture and maintenance period it is longer, mould development cost is higher, and need mating
Note stretch blow blow moulding machine on could use, and note stretch blow blow moulding machine equipment price on the market is generally costly, and
And step is more complex during article of manufacture, it is excessively high so as to cause production and maintenance cost；
(2) conversion between adjacent stations is needed to there is die bed base to carry out reheating, and energy consumption is higher.
The country also has partial monopoly for current domestic production one-step injection stretch blow equipment, and there are multistation to be difficult to ensure matter
The problem of amount, proposes a kind of new one-step injection stretch blow forming method.Such as a kind of pipe embryo of large capacity plastic bottle of Chinese patent
Injection molding forming method and pipe mould (publication number: CN105108974A), the pipe embryo for disclosing a kind of large capacity plastic bottle are molded into
Type method and pipe embryo mould are injected injection molding material by injection molding pipe embryo in temperature-controlled tube embryo mould, pipe embryo mould using injection molding forming method

Row refrigeration, guarantees cooling effect.Temperature display is set on main control panel, and temperature inductor connects the control of master controller
The control output end of input terminal, master controller connects temperature display.When temperature inductor senses that cooling device is intrinsic
When temperature, this information can be passed to master controller, master controller can show temperature by temperature display, facilitate operator
Member checks.Insulating layer is set outside cooling device ontology, can guarantee that the intrinsic temperature of cooling device will not be because of the external world
Temperature is affected, and guarantees cooling effect.
In one embodiment of the invention, 2 circulatory system of pipe embryo mold core and 8 circulatory system of pipe embryo die wall include hollow rubber
Sebific duct, cooling medium circulate in hollow rubber pipe, and pass through the first input port 6, the first delivery outlet 7, the second input port 16, the
Two delivery outlets 17 form cooling circuit in pipe embryo mold core 2 and pipe embryo die wall 8 respectively.
Certainly, above is representative instance of the invention, and in addition to this, the present invention can also have other a variety of specific implementations
Mode, all technical solutions formed using equivalent substitution or equivalent transformation, is all fallen within the scope of protection of present invention.
