Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is injection-molded item structural representation when being ejected.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Detailed description of the invention, is expanded on further the present invention.
Referring to Fig. 1 and Fig. 2, the present invention provides a kind of technical scheme: a kind of injection mold, including solid plate 5 and dynamic model
Plate 2, moving platen 2 is arranged on Bottom clamp plate 1, moving platen 2 has sprue body, is provided with guide pillar 3 in described solid plate 5,
It is provided with the first pilot hole 61 being slidably matched with described guide pillar 3 in described moving platen 2, also includes cover half seat 6 and portable plate 7,
Having the second pilot hole 62 and the 3rd pilot hole 65 on described cover half seat 6, one end of described solid plate 5 is in the second pilot hole 62
Sliding, the other end seals and coaxial package has described portable plate 7, described portable plate 7 and the guide rod 8 slided along the 3rd pilot hole 65
Connect, with the 2-in-1 mould of moving platen form forming cavity when solid plate 5 and portable plate 7 are pushed to certain position；Along the second pilot hole
The axial hole wall at the second pilot hole 62 of 62 has the first stopper slot 63, and described solid plate 5 is provided with the first limited block 51, edge
The axial hole wall at the 3rd pilot hole 65 of the 3rd pilot hole 65 has the second stopper slot 66, and described guide rod 8 is provided with the second limit
Position block 81, described second limited block 81 displacement in the second stopper slot 66 is less than the first limited block 51 at the first stopper slot
Displacement in 63；One end of described solid plate 5 forms, with the second pilot hole 62, the first chamber 64 sealed, at the first chamber
The first elastic component 9 that two ends are connected with the first limited block 51 and cover half seat 6 respectively is installed in 64, cover half seat 6 has with
The air inlet 68 of the first chamber 64 connection, described air inlet 68 is provided with electric control valve 100, and electric control valve 100 is used for
Regulate the gas pressure in the first chamber 64, described second limited block 81 and the 3rd pilot hole 65 and form the second chamber sealed
67, the second elastic component 10 that two ends are connected with the second limited block 81 and cover half seat 6 respectively is installed in the second chamber 67, described
First chamber 64 connects with the second chamber 67, and the most described first elastic component 9 and the second elastic component 10 are extension spring.
As shown in Figure 1, 2, during work, in the first chamber 64, keep certain pressure so that solid plate 5 and portable plate 7 by
Upper jack-up, owing to the first block and the existence of the second block, solid plate 5 and portable plate 7 will not continue to move up, then dynamic model
Plate 2 moves down, thus forms forming cavity with solid plate 5, portable plate 7, and feed liquid sprue body on moving platen 2 is injected into into
In die cavity, starting to eject injection-molded item 4 from solid plate 5 after cooled molding, moving platen 2 upwards separates, then by electricity
Dynamic regulation valve 100 suitably reduces the gas pressure in the first chamber 64 so that the power that the second limited block 81 is upwards pushed up by gas
The power pulled down less than the second elastic component 10, thus drive portable plate 7 to depart from the edge of injection-molded item 4, portable plate 7 is driven
Moving down, until no longer moving when the bottom of the lower surface of the second limited block 81 and the second stopper slot 66 abuts, continuing to reduce
Gas pressure so that the power that the power that solid plate 5 is upwards pushed up by gas pulls down less than the first elastic component 9, thus first is elastic
Part 9 drives solid plate 5 to move down, and injection-molded item 4 also moves down with solid plate 5, until the edge of injection-molded item 4 is with movable
When the upper surface of plate 7 abuts, injection-molded item 4 no longer moves down with solid plate 5, and is persistently reducing the situation of gas pressure
Under, solid plate 5 then moves down, until the lower end of the first limited block 51 abuts with the first stopper slot 63, solid plate 5 is the most no longer
Mobile, now, solid plate 5 separates with injection-molded item 4, and injection-molded item 4 is directly fallen in the collecting box of lower section.The note of the present invention
Mould, compact conformation, small volume.
The ultimate principle of the present invention and principal character and advantages of the present invention are more than shown and described, for this area skill
For art personnel, it is clear that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing substantially from the present invention spirit or
In the case of basic feature, it is possible to realize the present invention in other specific forms.Therefore, no matter from the point of view of which point, all should be by
Embodiment regards exemplary as, and is nonrestrictive, the scope of the present invention by claims rather than on state
