Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
A kind of top waste material mechanism includes bracket 1, retainer arm 3, mounting groove 1a is arranged at the top of bracket 1 combined with Figure 1 and Figure 2,
Retainer arm 3 cooperates in mounting groove 1a, and more compact by plugging shaft 1b realization between mounting groove 1a and retainer arm 3
Be rotatably assorted relationship；The two sides mounting groove 1a form side channel mouth through 1 side wall of bracket, and 3 both ends of retainer arm are stretched out from side channel mouth, and
One end forms Balance weight end, and the other end forms material receiving end.
As shown in Fig. 2, retainer arm 3 laterally offers sliding rail 3a in Balance weight end, horizontal sliding cooperates clump weight on sliding rail 3a
5, the structure of sliding rail 3a is strip-shaped hole in the present embodiment, and 5 carry of clump weight is in strip-shaped hole.The specific structure of clump weight 5 includes
Rolling element 5a and axis of rolling 5b, axis of rolling 5b longitudinally run through strip-shaped hole and respectively connect a rolling element 5a at both ends；Retainer arm 3 from
When horizontality becomes to tilt to Balance weight end, clump weight 5 can then be slided along sliding rail 3a to right end under self gravity, thus
Change the position of centre of gravity of retainer arm 3.Wherein, the shape of rolling element 5a preferably uses circle, guarantees along sliding rail 3a moving process
Operation smoothness.It should be noted that sliding rail 3a structure is not limited solely to strip-shaped hole, such as it is arranged to sliding groove structure, bar shaped
The linear tracks such as guide rail and configuration block cooperation all may be used.
Retainer arm 3 is relatively narrow with respect to Balance weight end in the vertical width of material receiving end, and weight is lighter, to guarantee clump weight 5 in sliding rail
Any position of 3a, center of gravity is always in Balance weight end；And since retainer arm 3 cooperates in mounting groove 1a, longitudinal thickness is smaller,
In order to guarantee preferably to dock deburring waste material, retainer plate 4 is fixed at the top of material receiving end.The longitudinal width of retainer plate 4 can root
Reasonable set is carried out according to waste material size, and retainer plate 4 is upturned to form flanging 4a far from one end of bracket 1；Participate in Fig. 4, folding
The effect of side 4a is to guarantee the deburring waste material separated from tablet towards Balance weight end, and in the rotation of retainer arm 3 later
Effectively deburring waste material is got to outside mold in journey；Flanging 4a is set, reduces waste material because of 4 edge out-of-flatness of retainer plate, or
The out-of-flatness of person's own form and a possibility that cause opposite direction to tilt, more reliable deburring waste material can be discharged outside mold.
In conjunction with Fig. 2 and Fig. 3, in order to control 3 inclination maximum of retainer arm, need in bracket 1 and 3 bracket 1 of retainer arm setting limit
Bit architecture, the present embodiment open up limiting slot 3b for compact type, using the Balance weight end bottom surface in retainer arm 3, pass through limit
The limit of 3 inclination maximum of retainer arm is realized in the cooperation of slot 3b and mounting groove 1a.Specifically seeing Fig. 3, limiting slot 3b is V-shaped, including the
One inclined-plane 3b1 and the second inclined-plane 3b2, the first inclined-plane 3b1 and the second inclined-plane intersection 3b2 arc transition；Fig. 4 is participated in, retainer is worked as
When arm 3 is in inclination maximum, the first inclined-plane 3b1 is fitted on the groove face of the bottom mounting groove 1a, and the second inclined-plane 3b2 clearance fit exists
On 1 side wall of bracket, collision of the notch point side limiting slot 3b to the bottom mounting groove 1a is avoided with this, steady contact is realized, reduces
Noise and damage to mounting groove 1a；And first inclined-plane 3b1 length be preferably greater than the second inclined-plane 3b2 so that the impact force of retainer arm 3
It can preferably scatter.
In conjunction with Fig. 2 and Fig. 4, pedestal 2 is installed in 1 bottom of bracket, pedestal 2 is used to entire mechanism being fixed on mold,
It is fixed between pedestal 2 and bracket 1 by connector 2b, connector 2b can select hexagon socket head cap screw structure, and from 2 bottom of pedestal
1 bottom of bracket is penetrated upwards；The settable groove in 2 bottom of pedestal, hexagon bolt head is hidden in groove.Pedestal 2 is propping up
Kidney slot 2a, relative position of the adjustable top waste material mechanism of kidney slot 2a structure on mold, with more preferable right is arranged in 1 two sides of frame
Connect deburring waste material.
In conjunction with Fig. 3 and Fig. 4, when tablet does not separate with deburring waste material, since tablet itself is heavier, retainer arm can be overcome
Retainer arm 3 is depressed into close to horizontality by the weight of 3 Balance weight ends, this appropriate to the occasion guarantee splicing end position is slightly lower, so that clump weight 5
It is moved to the position near the rotation point of retainer arm 3；After tablet and deburring waste material are cut off separation, balance originally is beaten
Broken, 3 Balance weight end of retainer arm rotates down, and material receiving end is upturned, at the same clump weight 5 along sliding rail 3a to far from 3 turns of retainer arm
The direction of dynamic point is mobile, accelerates retainer arm 3 to tilt, last limiting slot 3b and mounting groove 1a base channel face contact, retainer arm 3 stop
Movement；In the process, deburring waste material is then taken advantage of a situation downslide, completes deburring waste material slide-down process.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change
It also should be regarded as the protection scope of the utility model into replacement.
