Description
Technical field
The utility model belongs to injection molding technology field, particularly relate to a kind of hot flow path backward flow type into cementing
Structure.
Background technique
Traditional IML (film integrated molding) product into glue mode is to do side on one side into glue in certain of product.In this way, product
In injection moulding, since diaphragm is on the face PL, diaphragm can not be fixed on preceding die face when injection, and sizing material probably enters diaphragm
Reverse side, cause product bad, to influence the yield and production cost of product, and increase the size of diaphragm and subsequent NC adds
The cost at the work mouth of a river and period.
Summary of the invention
In order to overcome drawbacks described above, the utility model provide a kind of hot flow path backward flow type into plastic structure, not only into glue
Novel in structural design, structure is simple, and diaphragm fold and to prevent sizing material to be flushed to film anti-when can effectively improve injection molding
The defects of face, improves the yield of product.
The utility model is to solve technical solution used by its technical problem: a kind of hot flow path backward flow type into glue
Structure, including cope plate and lower template, the cope plate is interior to be equipped with upper cores, is equipped with lower mode in the lower template；The upper cores
Product die cavity is equipped between lower mode, which corresponds to the front of shaped article, the upper mold close to upper cores side
The front that benevolence corresponds to shaped article is equipped with thin film, and the product mold cavity bottoms are equipped with Jiao Kou, which passes through through described
The hot flow path docking molding machine gun mouth of lower template.
Be equipped with upper mounted plate above the cope plate as a further improvement of the utility model, the cope plate with it is upper
Fixed plate is fixedly connected；Ejector retainner plate, lower ejector retainner plate, bottom plate, tank plate and hot-fluid are successively arranged below the lower template
Road fixed plate, the upper ejector retainner plate are fixedly connected with lower ejector retainner plate, and ejector retainner plate and lower ejector retainner plate are equipped with across lower template on this
To the thimble of lower mode, tank plate is fixed on bottom plate, and oil cylinder is fixed on tank plate and is able to drive the upper thimble
Plate and lower ejector retainner plate move up and down；Hot runner plate is fixed on tank plate, and hot flow path sequentially passes through lower template, upper top
It is fixed on hot runner plate after needle plate, lower ejector retainner plate, bottom plate and tank plate.
The beneficial effects of the utility model are: 1. product shapes do not need to extend, diaphragm size size as product, from
And the size of diaphragm is saved.2. sizing material projects, moment fixes diaphragm, prevents diaphragm in the intracavitary movement of type, to keep away
Exempt from diaphragm and generates fold.In short, the utility model can be improved the yields of product, at the same can by vaporation-type hot flow path into
Glue can be to avoid processes such as the following process mouths of a river, to lower production cost and period.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In conjunction with attached drawing, make the following instructions:
1 --- upper mounted plate；2 --- cope plate；
3 --- lower template；4 --- upper ejector retainner plate；
5 --- lower ejector retainner plate；6 --- bottom plate；
7 --- tank plate；8 --- hot runner plate；
9 --- upper cores；10 --- lower mode；
11 --- oil cylinder；12 --- hot flow path；
13 --- product die cavity；14 --- thimble.
Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the patents and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
It is refering to fig. 1 a kind of hot flow path backward flow type described in the utility model into plastic structure, including cope plate 2 and lower die
Plate 3, the cope plate 2 is interior to be equipped with upper cores 9, is equipped with lower mode 10 in the lower template 3；Between the upper cores 9 and lower mode 10
Equipped with product die cavity 13, which corresponds to the front of shaped article close to 9 side of upper cores, and the upper cores 9 are corresponding
The front of shaped article is equipped with thin film, and 13 bottom of product die cavity is equipped with Jiao Kou, and the Jiao Kou is by running through the lower die
The docking molding machine gun mouth of hot flow path 12 of plate 3.
Wherein, it is equipped with upper mounted plate 1 above the cope plate, the cope plate is fixedly connected with upper mounted plate；Under described
Ejector retainner plate 4, lower ejector retainner plate 5, bottom plate 6, tank plate 7 and hot runner plate 8, the upper top are successively arranged below template
Needle plate is fixedly connected with lower ejector retainner plate, and ejector retainner plate and lower ejector retainner plate are equipped with the thimble 14 across lower template to lower mode on this,
Tank plate is fixed on bottom plate, and oil cylinder 11 is fixed on tank plate and is able to drive on the upper ejector retainner plate and lower ejector retainner plate
Lower back and forth movement；Hot runner plate is fixed on tank plate, and hot flow path 12 sequentially passes through lower template, upper ejector retainner plate, lower thimble
It is fixed on hot runner plate after plate, bottom plate and tank plate.
The hot flow path backward flow type into plastic structure in shaped article, using bottom glue-feeding, i.e., product mold cavity bottoms are touched
To hot nozzle, sizing material directly fills full entire type chamber from injection molding machine by hot flow path.IML (film integrated molding) product is traditional
It is to do side on one side into glue in certain of product into glue mode, product, since diaphragm is on the face PL (branch face), is penetrated in injection moulding
Diaphragm can not be fixed on preceding film surface when glue, and sizing material is likely to enter the reverse side of diaphragm, cause product bad.And the present invention uses bottom
Sizing material is accomplished the reverse side of product into glue mode by portion, firstly, product shape does not need to extend, diaphragm size is big as product
It is small, to save the size of diaphragm.Secondly, moment fixes diaphragm, prevents diaphragm in the intracavitary shifting of type when sizing material projects
It is dynamic, so that diaphragm be avoided to generate fold.
It can be seen that the utility model can not prevent the reverse side for accomplishing product into glue by bottom glue-feeding mode
Diaphragm avoids generating gauffer in the intracavitary movement of type, improves the yields of product, while can into glue by vaporation-type hot flow path
To avoid processes such as the following process mouths of a river, to lower production cost and period.
