Specific embodiment
The technical solution of the utility model is further elaborated with specific embodiment with reference to the accompanying drawing.
It is integrally formed injection mould, including upper mold 1 and lower die 2 referring to the blank overlay film of the utility model shown in Fig. 1 to Fig. 3,
Type chamber 3 is formed between upper mold 1 and lower die 2, injection mould further includes running channel 4, and running channel 4 is connected to by cast gate 41 with type chamber 3, is heated
Plastics are by forming blank in 4 inflow type chamber 3 of running channel.Upper mold 1 and lower die 2 all offer air intake passage, which includes
The negative pressure channel 5 being interconnected with type chamber 3, negative pressure channel 5 have one or have it is arranged in parallel a plurality of, wherein a negative pressure
The axial line in channel 5 and the axial line of cast gate 41 intersect vertically.In upper mold 1 and lower die 2, the number of negative pressure channel 5 is identical and position
Set one-to-one correspondence.Air intake passage further includes being connected to negative pressure channel 5 and extraneous conductive channel 6, the outer end connection of the conductive channel 6
There is the vacuum generator (not shown) that can generate negative pressure.
When producing plastics blank, the two sides cavity wall in type chamber 3 close to upper mold 1 and lower die 2 is respectively covered with one layer of blank film, very
Empty generator is to air-breathing in air intake passage, and the negative pressure that the oral area of negative pressure channel 5 generates fixes the absorption of blank film, and blank film is tight
It is tightly fitted in the top chamber wall and bottom chamber wall of type chamber 3, the hot melting plastic in subsequent running channel 4 flows between two blank films
Type chamber 3 in, after plastic shape-forming die sinking, obtained the blank of overlay film.Due to the blank film at the cast gate 41 by
Impact force it is maximum, so the blank film at this is easiest to shift, in the present embodiment, negative pressure channel 5, which is all disposed within, to be leaned on
At nearly cast gate 41, the most weak position of blank film is positioned, the spacing of the axial line of the oral area and negative pressure channel 5 of cast gate 41
For 12mm, the bore of cast gate 41 is 15mm, and the bore of negative pressure channel 5 is 6.0mm.
In the present embodiment, each air intake passage is provided with the negative pressure channel of three settings that are parallel to each other and are evenly spaced apart
5, the axial line for being located in the middle the axial line and cast gate 41 of negative pressure channel 5 intersects vertically.Between adjacent two negative pressure channels 5
Spacing is 15mm, it can be ensured that blank film, which is fixed, to be adsorbed, and not will receive the influence of impact force when cast gate 41 is poured and is caused to move
Position.
Shown in Figure 1, the connectivity part of all conductive channel 6 and the external world is all located at the same side of injection mould, therefore true
Empty generator is all connect in the same side of injection mould with injection mould, is arranged so so that wiring is more convenient, the wiring of gas circuit compared with
It is clear.
When it is implemented, being ordinatedly provided with air-breathing pin 7 in negative pressure channel 5, air-breathing pin 7 is with up and down through logical
Blank film can be adsorbed on the surface of type chamber 3 by the needle-shaped air intake duct in road, the negative pressure that vacuum generator generates through the air suction way,
Positioned at the side axial end of the air-breathing pin 7 of upper mold 1 and the upper cavity wall flush of type chamber 3, positioned at the air-breathing pin of lower die 2
7 side axial end and the lower cavity wall flush of type chamber 3 guarantee that the plastics whiteboard surface produced is smooth in this way.
Shown in Figure 3, on the injection mould of the present embodiment, there are two the settings of type chamber 3 of injection mould, and running channel 4 includes being located at
Main running channel 42 between two type chambers 3, the two points of running channels 43 being connected between main running channel 42 and type chamber 3, two points of running channels 43
Extend in the opposite direction along same axis, once-cast can make equal moulding plastics blank in the type chamber 3 of two sides simultaneously.
To sum up, the plastics blank overlay film of the utility model is integrally formed injection mould by the negative pressure of air intake passage for blank film
It is fixed in the bottom chamber wall and bottom chamber wall of type chamber 3, blank film will not be sent out after the molten plastic impact sprayed by cast gate 41
Raw deviation, injection mould directly produce the blank for having covered film, and the scrappage of injecting products is lower, and production efficiency is higher, simultaneously also
The film of different materials be can choose to carry out pad pasting in injection mould, increase diversity of the blank film in material selection.
