It is packed into lower 3 designated position of moving template.By the installation of mandril 10 on ejector retainner plate 18, screw putter 16 is loaded into thimble supporting plate 19, it will
One push rod guide pad 17 is finally assemblied in upper moving template 2, completes entire mechanism and exist by the upper assembly of moving template 2 on lower moving template 3
Assembling process on mold.
The course of work and principle:
In conjunction with shown in Fig. 2 and Fig. 4, when die sinking, using die sinking power drive KO mold insert 21 drive thimble supporting plate 19 and ejector retainner plate 18 to
Upper movement is fixed on ejector retainner plate 18 and also moves upwards therewith with the screw putter 16 on thimble supporting plate 19.Screw putter 16 is upward
When movement, the guide key groove 141 of 14 inside of spirally-guided key 161 and driving gear in 16 outside of screw putter generates extruding force,
To convert the ejecting force that KO mold insert 21 provides to the rotation of driving gear 14, and is engaged by gear and drive driven gear 12
The rotatory force of rotation, driven gear 12 is rotated synchronously by positioning key 11 with ejector half core 6.Due to the spiral in 16 outside of screw putter
Feather key 161 is adapted to the helical shape of 9 side of product, because cooperation mandril 10 ejects this type of core 6 in rotation, completes product
9 rotation ejects purpose.
When die closing, the problem of when the motion state and die sinking of above-mentioned each mechanism on the contrary, since there is no movement interference, therefore
The die closing stage, mechanism kinematic was without particular/special requirement.
Present invention take advantage of that the distinctive external physical characteristic design of product lateral surface helical gear, make to be difficult to form and demould originally
Shape is converted into the feature for capableing of convenient molding and demoulding, by the feature and helical teeth that the service life of gear is long and transmission power is big
The features such as wheel shaping precision is high, transmission is accurate simplifies mould structure, reduces mold manufacture and maintenance cost.
The application also provides a kind of injection-moulding device, including injection mold gear forming as described above and stripper apparatus；Tool
Body is as described above.
Driven gear is driven to rotate using die sinking power drive driving gear in conclusion the present invention passes through, thus with ejector half
Core rotation, type core be rotatably assorted thimble ejection make product stripping, be adapted to the product with biggish side helical teeth helical angle, protect
The effect of molding with demoulding is demonstrate,proved.
It should be understood that the application of the present invention is not limited to the above for those of ordinary skills can
With improvement or transformation based on the above description, all these modifications and variations all should belong to the guarantor of appended claims of the present invention
Protect range.
