Description
Technical field
Injection mold field is the utility model is related to, more specifically, the utility model is related to but be not limited in bottle base
Split type mold insert structure, bottle-blank injection mold and the injection molding system used in injection mold.
Background technology
Molding is the technique that will mould material formation molded article using molding-system.Such as injection molding process can be used
Molding process form various molded articles.Such as PET (PET) material is made with blow molding process
The performing member of the container for drink such as bottle.
Typical molded system includes injecting unit, fixture assembly and mold assemblies.Injecting unit can be reciprocating
Screw type or diarcs.Fixture assembly includes framework, displacable platen, fixation clip and for moving displacable platen simultaneously especially
And apply the actuator of tonnage to the mold assemblies being configured between pressing plate.Mold assemblies especially include cold half and heat half
Portion.Therefore hot half is generally associated with one or more die cavitys (and to be also referred to as by those skilled in the art sometimes
" die cavity half portion "), and cold half is generally associated with one or more core rods (and therefore sometimes also by the skill of art
Art personnel are referred to as " mould core portion ").One or more die cavitys and one or more core rods in use together with define one
Individual or more than one molding cavity.Hot half also can be with the melt distribution systems distributed for melt (sometimes also by art
Technical staff is referred to as " hot runner ") it is associated.Mold assemblies can be with such as neck ring, neck ring slides, displacer structure, wear-resisting
Many additional assemblies of pad etc. are associated.
As explanation, PET material it is injection-molded be related to PET material (for example, PET pills, PEN powder, PLA etc.) plus
The PET material so melted is expelled at least partly by being respectively arranged in mould by heat under stress to homogeneous molten state
One or more foregoing die cavitys in the mold cavity plate and mold core plates of sub-assembly and one or more core rods define one
In individual or more than one molding cavity.Mold cavity plate and mold core plates are pushed to together and kept it in together by chucking power, institute
Chucking power is stated to be enough to resist the pressure of injected PET materials and die cavity and core piece keep together.Molding cavity has real
Correspond to the shape of the final cold-state shape of molded article to be molded in matter.The PET material so injected is then cooled to foot
The temperature that the molded article being thusly-formed with enabling is discharged from mould.In cooling, molded article is received inside molding cavity
Contracting, and therefore when forcing mold cavity plate to be separated with mold core plates, molded article tends to keep associated with core rod.Therefore, pass through
Force mold core plates to be stripped away from mold cavity plate, molded article, i.e., discharged from core piece.Known discharge structure is aided in from core rod half portion
Remove molded article.The example of discharge structure includes stripper plate, jemmy etc..
At present, different bottle blank structures are directed to, the difference of its production mould essentially consists in the difference of core rod and die cavity, other
Structure has realized generalization.Therefore change produce bottle base prefabrication when, producer need to only design corresponding core rod and
Mold cavity configuration.It is a production cycle that mould molds matched moulds every time, and each production cycle is about 5 minutes.Produced in mould
In cycle, core rod is by the impulsive force of the plastic liquid sprayed from cast gate, the heat exchange and internal core rod that plastic liquid is brought
The cooling effect of cooling tube.During frequently matched moulds is molded, core rod is ceaselessly influenceed by above-mentioned three kinds of factors, easily
Produce fatigue and damage；Therefore, in actual production process, core rod is also that most frequent component is changed in a whole set of preform mould.
Also, core rod length is longer in the prior art current, it runs through the accommodating chamber of whole core rod supporting part, more using raw material,
Need to process local more, therefore the cost for processing core rod is higher.Meanwhile it is this design in the mould that uses, use its
His component is also more, also increases material and assembly cost.
Utility model content
The utility model provides the bottle base note that a kind of energy saves more material, reduces processing cost and can meet production requirement
The split type mold insert structure of mould.
Second purpose of the present utility model is that one kind can save more material, reduces processing cost and can meet that production will
