Specific implementation mode, the present invention is further explained.
It please refers to Fig.1 and Fig. 2, the present invention provides a kind of technical solution：A kind of injection mold, including solid plate 5 and dynamic model
Plate 2, moving platen 2 are mounted on Bottom clamp plate 1, sprue body are provided on moving platen 2, guide post 3 is provided in the moving platen 2,
It is provided with the first pilot hole 61 being slidably matched with the guide post 3 in the solid plate 5, further includes cover half seat 6 and movable plate 7,
The second pilot hole 62 and third pilot hole 65 are provided on the cover half seat 6, one end of the solid plate 5 is in the second pilot hole 62
Sliding, other end sealing and coaxial package have the movable plate 7, the movable plate 7 and the guide rod 8 slided along third pilot hole 65
Connection molds with moving platen 2 when solid plate 5 is pushed to certain position with movable plate 7 and forms forming cavity；Along the second pilot hole
The 62 axial hole wall in the second pilot hole 62 is provided with the first limiting slot 63, and the solid plate 5 is equipped with the first limited block 51, edge
The axial hole wall in third pilot hole 65 of third pilot hole 65 is provided with the second limiting slot 66, and the guide rod 8 is equipped with the second limit
Position block 81, displacement distance of second limited block 81 in the second limiting slot 66 are less than the first limited block 51 in the first limiting slot
Displacement distance in 63；One end of the solid plate 5 forms the first chamber 64 of sealing with the second pilot hole 62, in first chamber
The first elastic component 9 that both ends are connect with the first limited block 51 and cover half seat 6 respectively is installed in 64, be provided on cover half seat 6 with
The air inlet 68 that first chamber 64 is connected to is equipped with electric control valve 100 on the air inlet 68, and electric control valve 100 is used for
The gas pressure in first chamber 64 is adjusted, second limited block 81 forms the second chamber of sealing with third pilot hole 65
67, the second elastic component 10 that both ends are connect with the second limited block 81 and cover half seat 6 respectively is installed in second chamber 67, it is described
First chamber 64 is connected to second chamber 67, and preferably described first elastic component, 9 and second elastic component 10 is tension spring.
As shown in Figure 1, 2, when work, certain pressure is kept in first chamber 64 so that solid plate 5 and movable plate 7 by
Upper jack-up, due to the presence of the first block and the second block, solid plate 5 and movable plate 7 will not continue to move up, then dynamic model
Plate 2 moves down, and to form forming cavity with solid plate 5, movable plate 7, feed liquid is injected into through the sprue body on moving platen 2
In cavity, start to eject injection-molded item 4 from solid plate 5 after cooling and shaping, moving platen 2 separates upwards, then passes through electricity
Dynamic regulating valve 100 suitably reduces the gas pressure in first chamber 64 so that the power that the second limited block 81 is pushed up upwards by gas
Less than the power that the second elastic component 10 pulls down, to drive movable plate 7 and the edge of injection-molded item 4 to be detached from, movable plate 7 is driven
It moves down, is no longer moved when the lower surface of the second limited block 81 is abutted with the bottom of the second limiting slot 66, continue to reduce
Gas pressure so that the power that solid plate 5 is pushed up upwards by gas is less than the power that the first elastic component 9 pulls down, to the first elasticity
Part 9 drives solid plate 5 to move down, and injection-molded item 4 is also moved down with solid plate 5, until the edge of injection-molded item 4 and activity
When the upper surface of plate 7 abuts, injection-molded item 4 is no longer moved down with solid plate 5, and the lasting reduction gas pressure the case where
Under, solid plate 5 then moves down, and until the lower end of the first limited block 51 is abutted with the first limiting slot 63, solid plate 5 is also no longer
Mobile, at this point, solid plate 5 is detached with injection-molded item 4, injection-molded item 4 is directly fallen into the collecting box of lower section.The note of the present invention
Mould, compact-sized, small volume.
