9, de- material driving plate 10, preceding model cavity fixed plate 11, rear mold core fixing plate 12, ejection cushion block 13, rear baffle plate 14.
The preceding mould internal core-pulling mechanism is applied to the preceding mould elder generation core-pulling mechanism occasion of injection mold, institute's application mold knot
Structure composition includes preceding die face plate 9, de- material driving plate 10, preceding model cavity fixed plate 11, rear mold core fixing plate 12, ejection cushion block
13, rear baffle plate 14；It is three template die mould with pin point gate using mold, mold parting is opened in three times, respectively P1, P2, P3 tri-
Secondary parting.
In the preceding mould internal core-pulling mechanism, model cavity fixed plate 11 before preceding model cavity mold insert 1 is fastened on by screw
On；Before sliding groove seat 2 is fastened on by screw on model cavity mold insert 1, side core-pulling core sliding block 4 is installed on sliding groove seat 2,
It is coupled between the two by T-slot, the upper end of side core-pulling core sliding block 4 is set as T-slot form, can be in sliding groove seat 2
Horizontal direction horizontally slips；Core-pulling slide block driving spring 3 is installed in the spring eye of side core-pulling core sliding block 4, inner sleeve
Equipped with limit pull rod 8, limit pull rod 8 passes through the screw rod via on preceding model cavity mold insert 1, and left end is by preceding model cavity mold insert 1
Hole end surface carries out limit positioning, right end and 4 spiral marking connection of side core-pulling core sliding block；Side core-pulling core sliding block 4 is used for mould before product
The core_pulling demoulding of side button bit.
It, can be along lock before latch segment 7 is installed in the closing piece hole of model cavity fixed plate 11 in the preceding mould internal core-pulling mechanism
Block hole moves up and down, and the upper end of latch segment 7 is equipped with latch segment spacer pin 6, and latch segment spacer pin 6 passes through preceding model cavity fixed plate
11 Kong Houyu latch segments 7 are coupled, and are set with latch segment driving spring 5 on latch segment spacer pin 6, pass through latch segment driving spring
5 drive latch segment 7 to be drawn upwardly out, with release mold after locking of the latch segment 7 to side core-pulling core sliding block 4.Limit pull rod 8 is grown
Degree can be 40-120cm.
In the preceding mould internal core-pulling mechanism, the cooperation of latch segment 7 and side core-pulling core sliding block 4 is driven to T-slot cooperation and drives
It is dynamic, the driving of side core-pulling core sliding block 4 is used when latch segment driving spring 5 plays core pulling, latch segment 7 slides side core-pulling core
Block 4 plays the role of driving locking effect when startup and mold closing.
In actual work, the application method (course of work) of the mold is divided into following steps：
1) institute's application mold is closed after the completion of injection molding, and mold is opened first at P1 die joints, de- material driving plate 10,
The preceding separation of model cavity fixed plate 11 is opened, and is completed runner waste material and is detached with breaking for product, synchronous with this to carry out, latch segment
The upper end of spacer pin 6 loses the compacting of de- material driving plate 10, thus, under the rebound driving of latch segment driving spring 5, latch segment
Driving spring 5 drives latch segment spacer pin 6 upwards, and to drive latch segment 7 to be lifted up, driving latch segment 7 is matched by T-slot
It closes that the lateral extraction to the right of side core-pulling core sliding block 4, side core-pulling core sliding block 4 is driven synchronously to be also at core-pulling slide block driving
Under the promotion to the right of spring 3, when latch segment 7 runs to upper end, is blocked by preceding model cavity fixed plate 11, uplink cannot be continued,
To ensure that latch segment 7 there can be certain contact with side core-pulling core sliding block 4, to ensure that such contact can be reliable, while also protecting
Card side core-pulling core sliding block 4 is not deviate from from sliding groove seat 2, is held to it by limit pull rod 8, ensures it not from sliding
Deviate from groove seat 2, the distance that side core-pulling core sliding block 4 skids off to the right can meet core_pulling demoulding row recessed on the inside of mould before product
Journey；7 stroke of latch segment is H, and the movement core pulling stroke of corresponding side core-pulling core sliding block 4 is L.
2) when closed reduction, process is on the contrary, suppressing latch segment spacer pin 6 by de- material driving plate 10 by driving latch segment 7
Downlink is moved to the left reset to force latch segment 7 to oppress side core-pulling core sliding block 4, and mold is closed completely at P1 die joints
When, side core-pulling core sliding block 4 also resets completely.
Specific embodiment described herein is only an example for the spirit of the invention, technology neck belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
