The end face of plastic 57.
Perforative third through-hole is provided in the bottom plate 13.The both ends of the mold connect with injection molding machine respectively, injection molding
Machine is corresponding to mandril is provided at the position of the third through-hole, and when dynamic model backs to certain position, the mandril passes through the
Three through-holes withstand thimble push plate 12, and thimble push plate 12 and thimble cover board 11 is made to push the movable mould push plate 7 by plastic 57 and mo(u)ld bottom half
Core mold insert 20 separates.
It is further improved compared to above scheme, is provided with ejecting limit block 25 on the thimble cover board 11.
It is further improved compared to above scheme, hole foot type needle 22 is provided in the through-hole on 57 end face of plastic, it is described
Foot type needle 22 through hole foot type needle pressing plate 15 in hole is fixed.
It is further improved compared to above scheme, the ejection limit pull rod 26 is cylindrical.
It is further improved compared to above scheme, the 5th elastic device 51 is spring, the symmetry axis of the spring
It is parallel with the symmetry axis of the guide post 52.
The working principle of the invention is simply illustrated below:
1) die closing is molded.After mold is installed on injection molding machine, closure, injection molding machine is injected molten plastic in die cavity by nozzle；
2) it is opened.When die sinking, point 6 steps realize the automated production of plastic 57:
1. the first die joint 41 is opened.Mold dynamic model retreats, and the first die joint 41 is opened, and waste material and plastic 57 are in spot pouring mouth position
Place disconnects separation, and plastic 57 stays in die cavity, and waste material is then held by sprue puller 2727 and gate bush 1, is stayed on stripper plate 4；
2. the second die joint 42 is opened.Mold dynamic model continues to retreat, and the second die joint 42 is opened, and stripper plate 4 expects waste material from drawing
It is scraped on bar 27 and gate bush 1, realizes the automatic demoulding of runner waste material；
3. third die joint 43 is opened.Mold dynamic model continues to retreat, and injection molding machine mandril withstands thimble push plate 12, fills in third elasticity
Under the action of setting 32, dynamic model is first in the opening of third die joint 43, opening, and moving template 8 and dynamic model backing plate 9 separate, plastic 57
Four hole Kong Xianyu foot type needles 22 of hole foot be detached from, demoulding finishes, and moving template 8 ejects limit pull rod 26 by moving template 8 and holds, no
It can continue uplink；
4. tetrad segregation types face 44 is opened.Mold dynamic model continues to retreat, and tetrad segregation types face 44 is opened, when opening, solid plate 5 and dynamic model
Push plate 7 separates；
5. the 5th die joint 45 is opened.While tetrad segregation types face 44 is opened, the 5th elastic device 51 on not sliding block 19 is being breathed out
Driving under, left half sliding block, right half sliding block synchronization are laterally extracted out to two sides, i.e. 45 die joint of the 5th die joint is opened, and is being limited
Under the pulling of hook 21, left half sliding block, right half sliding block can only slide on the face along movable mould push plate 7, and from the chamber in solid plate 5
Abjection, abjection are separated to distance, left half sliding block, right half sliding block is centainly arrived with plastic 57, plastic 57 cannot catch on half sliding block of a left side,
Right half sliding block, so that left half sliding block, right half sliding block can be separated with movable mould push plate 7；Plastic 57 is stayed on mo(u)ld bottom half core mold insert 20；
6. the 6th die joint 46 is opened.Mold dynamic model continues to retreat, and injection molding machine mandril withstands thimble push plate 12 and ejects upwards, thus
Movable mould push plate mandril 14 and movable mould push plate 7 eject upwards, thus movable mould push plate 7 push plastic 57 on mo(u)ld bottom half core mold insert 20 along
Helical teeth rotation demoulding provides lubricating action, plastic 57 is inlayed from mo(u)ld bottom half core because there are powder particles on plastic 57 during rotation
It is fallen on part 20, automatic demoulding；
7. resetting.Reseting procedure is opposite with die sinking process.
