Specific embodiment
Below in conjunction with attached drawing, by the description to preferred embodiments of the present invention, more clearly and completely explain
State the technical solution of the utility model.
Embodiment: Fig. 1, bullet block auxiliary ejection device, including rear cavity 1 and front cavity 2, the upper surface of front cavity 2 are referred to
It is provided with type groove 3, product passes through the molding of rear cavity 1 and front cavity 2 and is formed in type groove 3, is vertically arranged in front cavity 2
The ejection slot 4 being connected to type groove 3 slidably connects movable insert 5 along ejection slot 4, after the completion of product is molded in pattern, activity
Mold insert 5 pushes product to be detached from type groove 3 by upward sliding, cooling meat is generated after being detached from type groove 3, since product loses type groove
3 shape limitation, thus product have it is biggish allow bit space, reduce product and occur drawing white situation.
With reference to Fig. 2, eject and be equipped with ejector spring 6 in slot 4, the both ends of ejector spring 6 respectively with movable insert 5 and ejection
Slot 4 contradicts, and the effect of setting ejector spring 6 is, can when rear cavity 1 and front cavity 2 separate, ejector spring 6 can automatically by
Product ejects type groove 3, and specific step is that rear cavity 1 and front cavity 2 mold first, the upper surface of movable insert 5 and type groove
3 lower surface maintains an equal level, and movable insert 5 compresses ejector spring 6, and product is injection molding in type groove 3, then after the completion of product injection molding,
Rear cavity 1 and front cavity 2 separate, and ejector spring 6 itself has talked recovery, and movable insert 5 restores due to the deformation of ejector spring 6
Power, which is moved up, releases type groove 3 for product, and after product after the outer cooling meat of type groove 3, rear cavity 1 and front cavity 2 mold again
Injecting products are carried out again, and so on, are reduced product and are drawn white situation in type groove 3.
With reference to Fig. 2, it is provided with convex block 7 on the peripheral wall of movable insert 5, ejects the guide groove for being provided in slot 4 and sliding for convex block 7
8, it, both can be axial when rear cavity 1 and front cavity 2 mold to avoid movable insert 5 by being slidably matched for convex block 7 and guide groove 8
Rotation, can also avoid the bullet due to ejector spring 6 by the stroke of 5 upward sliding of length limitation movable insert of guide groove 8
Power, movable insert 5 are detached from when rear cavity 1 and front cavity 2 are separated from the upper surface of front cavity 2 and front cavity 2.In order to avoid top
There is the case where deviation in its middle section in compression of spring 6 out, therefore ejects and limited folding column 9 is arranged in slot 4, and limit folding column 9 is interspersed in
In ejector spring 6, the axis direction of limit folding column 9 and pop-up.It is provided with lower limit column 13 in front cavity 2, is provided on movable insert 5
For the slot 14 of limit folding 9 grafting of column, lower limit column 13 moves down stroke limit to movable insert 5.
With reference to Fig. 5, in order to increase the forced area between movable insert 5 and product, to reduce when product is pushed
Pressure, and then reduce product and the case where deformation occur due to the conflict of movable insert 5, movable insert 5 is in front cavity 2
Altogether there are two settings.In addition to keep the active synchronization of two movable inserts 5, reduce that product local pressure is excessive causes to become
Shape with reference to Fig. 3 and Fig. 4, therefore is connected with synchronous key group 10 between two movable inserts 5, and synchronous key group 10 includes connector
101, link slot 102 is provided on two movable inserts 5, swivel nut 103 is plugged in link slot 102, and the side of swivel nut 103 turns
There are two swing rod 104, the other end of two swing rods 104 is rotatably connected to strut 105, the other end of two struts 105 for dynamic connection
It is mutually rotatablely connected, bolt 106 is threaded in swivel nut 103, bolt 106 passes through connector 101.Connector 101 and activity
When mold insert 5 connects, swivel nut 103, swing rod 104 and strut 105 are inserted into link slot 102 by setter first, are then installed
Bolt 106 is passed through connector 101 and connect bolt 106 with the inner thread of swivel nut 103 by person, and bolt 106 contradicts two supports
The junction of bar 105 simultaneously drives strut 105 to prop up in the inner wall of link slot 102, and then swivel nut 103 and movable insert 5 are fixed, lead to
It crosses bolt 106 and connect connector 101 with two movable inserts 5 respectively.
With reference to Fig. 5, in order to further increase the conflicts area of movable insert 5 and product and reduce the feelings that product stress is damaged
Condition, therefore be provided in the upside of movable insert 5 and increase panel 11, the bottom side of type groove 3 is provided with the placement placed for increasing panel 11
Slot 12.
Above-mentioned specific embodiment is only described preferred embodiments of the present invention, and not practical to this
Novel protection scope is defined.Under the premise of not departing from the utility model design conception and scope, this field
Those of ordinary skill is according to verbal description provided by the utility model, attached drawing to made by the technical solution of the utility model
Various modifications, substitution and improvement should belong to the protection category of the utility model.The protection scope of the utility model is wanted by right
