Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figure 1, be optimum embodiment of the present invention, a kind of swing hook convex block cover half demoulding mechanism, including fixed clamping plate 6,
Cover half 5, pusher plate 3 and dynamic model 1, when not demoulding state, the rear end face of cover half 5 is fixedly connected with fixed clamping plate 6, before cover half 5
End face connects (connection of contact) with the rear end face of pusher plate 3, and the front end face and dynamic model 1 of pusher plate 3 connect the (company of contact
Connect), contact connection only connects, be not bonded or combine together etc., for example, pusher plate 3 only and
Cover half 5 contacts, and guarantees that pusher plate 3 may exit off cover half 5 in die sinking, the front end face and dynamic model 1 of pusher plate 3 connect, equally only
It is contact, it is not necessary to worry, pusher plate 3 can fall down, and have guide post to pass through pusher plate 3, and pusher plate 3 is supported, is not drawn into guide post figure,
There is plastic type chamber, plastic type is intracavitary for being molded plastic 2, and cover half demoulding mechanism further includes in cover half 5, pusher plate 3 and dynamic model 1
Demould pushing component, demoulding pushing component includes limit pull rod 8, swing hook 7, spring 10 and pin shaft 4, the rear end of limit pull rod 8 and
The outside of cover half 5 and fixed clamping plate 6 is fixedly connected, and the front end of limit pull rod 8 limits and draws to 1 outside horizontal extension of dynamic model
The front end of bar 8 is upwardly formed integrated limit pull rod convex block 81, and swing hook 7 is in tiger's jaw shape, and the bending part of the tiger's jaw of swing hook 7 passes through
Shaft 9 is rotatably installed in the outside of dynamic model 1, and the tiger's jaw of swing hook 7 is open towards rear, and the lower end of swing hook 7 is extended with straight down
Swing hook convex block 71, the upper end forward fold of swing hook 7 have coupler body 72, and coupler body 72 is located at the outside of cover half 5 and fixed clamping plate 6, bullet
The upper end of spring 10 is connected with the outside of dynamic model 1, and the lower end of spring 10 and swing hook 7 connect, the lower end of spring 10 and the connection of swing hook 7
Between shaft 9 and coupler body 72, spring 10 tilts backwards point from top to bottom, 4 evagination of pin shaft and is fixedly installed in pusher plate 3
Outside, pin shaft 4 are higher than shaft 9 and are lower than coupler body 72, and the opening of coupler body 72 is towards pin shaft 4, and the bottom of swing hook convex block 71 is lower than limit
The top of position pull rod convex block 81, the bottom of swing hook convex block 71 are not contacted with limit pull rod 8, and it is convex that swing hook convex block 71 is located at limit pull rod
The rear of block 81.Swing hook convex block 71 and the opposite wedge shaped cooperation in face of limit pull rod convex block 81, lozenges is from the bottom to top to limit
Pull rod convex block 81 tilts.There is spacing between swing hook convex block 71 and limit pull rod convex block 81.
Working principle: limit pull rod 8 is fixedly mounted on cover half 5 and fixed clamping plate 6, and swing hook 7 is rotatablely installed by shaft 9
On dynamic model 1, in addition there is spring 10 to connect with dynamic model 1 on swing hook 7,7 upper right side of swing hook (visual angle in figure) is coupler body 72, swing hook 7
After lower end has downwardly convex swing hook convex block 71, swing hook convex block 71 and limit pull rod convex block 81 to collide, it may make swing hook 7 along shaft
9 rotations.Pin shaft 4 is fixed in pusher plate 3, coupler body 72 can hook pusher plate after swing hook 7 is moved to the left certain distance with dynamic model 1
Pin shaft 4 on 3, pusher plate 3 push hairbrush plastic 2 to demould.
Specifically, when parting, dynamic model 1 and 5 parting of cover half, the direction of dynamic model movement are front, and pusher plate 3 and dynamic model 1 are temporary
When do not connect, so pusher plate 3 is temporarily motionless, pusher plate 3 and cover half 5 are connected.When dynamic model 1 is moved to certain distance (enough modelings
Part 2 deviates from dynamic model 1) when, swing hook convex block 71 is just collided with limit pull rod convex block 81, is further continued for pulling dynamic model 1,7 inverse time of swing hook
Needle overturning, coupler body 72 hook pin shaft 4, and swing hook convex block 71 and 81 wedge surface of limit pull rod convex block cooperate, edge after swing hook convex block 71 squeezes
Wedge surface downslide certain distance, swing hook convex block 71 and limit pull rod 8 contradict, and after coupler body 72 hooks pin shaft 4, pusher plate 3 is reversely pushed
Plastic 2, so that plastic 2 demoulds.In knockout course, spring 10 hauls swing hook 7, so that swing hook 7 hauls pusher plate 3 always.
When molding, after the external force of demoulding disappears, the restoring force of spring 10 plays a role, and swing hook convex block 71 is retracted, coupler body 72
It rotates clockwise, unclamps pin shaft 4, reset and complete.
Before swing hook convex block 71 collides between limit pull rod convex block 81 at a distance from walking, it is exactly equal to the pin shaft 4 of pusher plate 3
Distance into the coupler body 72 of swing hook 7 guarantees that swing hook 7 can hook pusher plate 3 in time, completes demoulding.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
