Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
As illustrated, the operation principle when present invention divides mould：After injection molding completion, cope plate takes off out of die cavity
Open, because the projection of lower template right side wall is also inserted in moulding side wall, so, moulding will not follow cope plate together from type
Intracavitary departs from, i.e., the projection of template right side wall can play spacing effect；
In mold process is divided, if using the drive device more saved, i.e., including the first magnet assemblies, the second group of magnets
During the drive device of the parts such as part, motor driven rotating shaft rotates along a direction all the time, the second magnetic in rotating shaft
When the first arc-shaped magnet turns to the region with bar magnet face in iron component, due to the S poles of the first arc-shaped magnet and bar shaped
The S of magnet bottom is extremely mutually exclusive, so as to drive bar magnet and shell to move up, that is, passes through first straight line rack
To cause travelling gear to rotate clockwise, swing rod also rotates counterclockwise engaged transmission with travelling gear, on swing rod
End turns left；, can matching somebody with somebody by the first straight pin and the first open slot during being turned left in swing rod upper end
Close to drive second straight line rack to be moved to the left, second straight line rack is by the transmission of first gear and the 3rd linear gear rack with band
Dynamic side template moves right；Simultaneously as swing rod upper end is swung to the left can drive drive rod rotation, drive link can be relative to horizontal stroke
Bar and swing rod rotate, and drive link can integrally push cross bar and be moved to the left along guide pin bushing axis, the cross bar meeting being moved to the left
Lower template is pulled also to be moved to the left to cause projection to be extracted from moulding side wall；That is, the motion of lower template and side template
Direction is opposite, that is, is located remotely from each other, so as to which operating personnel's can takes out moulding out of mould；In a word, in lower template
During being located remotely from each other with side template, also relative to side template inwall relative displacement can occur for moulding, the peace on moulding
Relative displacement can be occurred relative to projection outer wall by filling hole；
When the second arc-shaped magnet in the second magnet assemblies and bar magnet face, due to the N poles of the second arc-shaped magnet
Attract each other with the S poles of bar magnet bottom, so as to drive bar magnet and shell to move down, and then drive successively
Other parts counter motions, until matched moulds is completed.Because the second arc-shaped magnet takes 3/4ths girths on same circumference,
That is, rotating shaft drives the second magnet assemblies to rotate in a turnaround time, a quarter time be the first arc-shaped magnet with
For bar magnet face for dividing mould, 3/4ths times were the second arc-shaped magnet and bar magnet face for matched moulds.Institute
It is three times that worker's pickup time is supplied after point mould with, injection time after matched moulds of the present invention, so can both ensures needed for matched moulds
The time wanted, pickup after dividing mould can be given to provide time enough again, improve automatic die assembly injection with dividing the work of mould pickup to imitate
Rate.
