To describe technology contents of the invention, structural feature, the objects and the effects in detail, below in conjunction with implementation method
And coordinate accompanying drawing to be explained in detail.
Fig. 1 is referred to, one kind rotation is de- to move back mold mechanism, including the de- unit of rotation and multiple tooth core units, multiple tooth core unit rings
It is around in the de- unit of the rotation；
The de- unit of rotation includes rifling 11, rifling department set 12, and rifling department set is socketed on the rifling,
Rifling department set inner side is correspondingly provided with the internal thread and external screw thread being adapted with rifling outside, and the rifling department set outside sets
There is bearing 13, the outside of bearing 13 is provided with master gear 14；
The tooth core unit includes tooth core 15, tooth core mold insert 16, rotation stop gear and facing 17, and the tooth core mold insert 16 is set
In the one end of tooth core 15, facing 17 is arranged at the other end of tooth core 15, and the facing 17 is provided with screw thread guide frame, the tooth core edge
Part 16 is connected by rotation stop gear with tooth core 15, and the tooth core 15 is provided with from gear 18, the tooth core 15 by from gear 18 with
The engagement linkage of master gear 14 of the de- unit of rotation.
Knowable to foregoing description, the beneficial effects of the present invention are：By the reciprocating motion of rifling, make rifling department
Set, bearing and master gear are rotated, then drive tooth core to rotate, and coordinate the screw thread guide frame of the facing of tooth core bottom, make tooth core ribbon
Movable property product are retreated, and because the effect of the rotation stop gear of tooth core mold insert will not follow rotation, thus reach the purpose that rotation takes off core pulling, real
Showed the die sinking of product stripping and mould synchronously carry out, substantially increase production efficiency.
Embodiment 1
Rotation is de- when moving back mould, and rifling axially movable, drives rifling department set to rotate, by master gear drive tooth core from
Gear, tooth core follows rifling department set to be rotated, and tooth core unit drives tooth core in the presence of the screw thread guide frame of facing
Moved to facing extreme direction, tooth core mold insert does not follow tooth core to rotate in the lump, treats that rifling is moved to due to rotation stop gearing
Position, revolves de- unit and is stopped, and tooth core unit also revolves and moves on to position, and rotation is de- to move back mould action completion；
Move back after the completion of mould, rifling carries out counter motion vertically, drive rifling department set to rotate backward, by master gear
Drive tooth core from gear, tooth core follows rifling department set to be rotated backward, screw thread guide frame of the tooth core unit in facing
In the presence of, drive tooth core to be moved to the opposite direction at facing end, treat that rifling resets, the de- unit of rotation is stopped, tooth core unit
Also rotation is moved and resetted.
From the foregoing, it will be observed that take off moving back mold mechanism using the rotation of reflex wire type, the product for possessing internal thread can be made in injection moulding
After the completion of, while the demoulding, the externally threaded mould that is provided with the inside of product is detached into product by tooth core, realize die sinking with
The effect that the demoulding is carried out simultaneously, effectively saves the production time, improves production efficiency.
Take off and move back mold mechanism the invention further relates to a kind of injection machine, including injecting mechanism and rotation, the injecting mechanism can be separated
Be arranged at that rotation is de- to move back above mold mechanism, the injecting mechanism includes multiple injecting heads, multiple injecting heads and the Tui Mo mechanisms
