At screw drive structure, 173 bottom of protruding pin bar is connect with 7 guide rail of type core bar fixed plate, the head of protruding pin bar 173 and roller 174
Hinge connection, 172 lower end of shaft passes through lower bar holder 175, and is positioned with circlip 176, when joint transfers stop nut 21 and phase
Can reach when answering protruding pin 173 position of bar adjust side core-pulling away from.It is specific as follows, if side core-pulling away from tuning up,
Rotary stopper nut 21 moves it up, while rotating the shaft 172 of protruding pin combination unit 17, keeps protruding pin bar 173 also upward
Mobile same distance, this purpose are the time that synchronizing relay drag hook bar 16 rotates counterclockwise, and such side core-pulling is away from becoming larger；Together
Reason, if opposite direction rotary stopper nut 21 moves down it, while rotating protruding pin group side core-pulling away from turning down
Attach together set 17 shaft 172, so that protruding pin bar 173 is moved down same distance, this purpose is to occur that drag hook bar 16 counterclockwise
The time of rotation tails off, and such side core-pulling is away from becoming smaller.
Type core bar group 19 is by type pin head 191, type core bar 192, type core throw-out collar 193, pull rod 194, sliding block 195 and pressure spring
There are external screw thread in 196 compositions, 192 one end of type core bar, and the other end is convex shoulder, and type core throw-out collar 193 is threadedly coupled with type core bar 192, type
191 bottom surface of pin head have internal thread hole and be threadedly coupled at the top of type core bar 192,195 empty set of sliding block on type core bar 192,
Pressure spring 196 is arranged at 195 lower part of sliding block, and pressure spring 196 is mounted in the groove of type core bar fixed plate 7, and 4 pull rods 194 are symmetrically distributed in
The both sides of sliding block 195,194 1, pull rod connect with 195 hinge of sliding block, and other end and left side core sliding block 3 or right side core are slided
The connection of 24 hinge of block, type core bar 192 is located between type core bar fixed plate 7 and type core bar support plate 8 with convex shoulder, when die sinking, mould
For tool from die joint parting, solid plate 1 is motionless (since 161 part of gib head in drag hook bar 16 contacts with each other with hook pin 18, so type
Cavity plate 2 and moving template 6 are also fixed)；Type core bar fixed plate 7, type core bar support plate 8, backing plate 9 and Bottom clamp plate 12 are being injected
It is retreated together under the action of machine, since studs 20 is threadedly coupled with type core bar fixed plate 7, so studs 20 is also followed
It moves down；Since the type core bar 192 of type core bar group 19 is fixed between type core bar fixed plate 7 and type core bar support plate 8, so
Type core bar 192 also and then moves down, and when type core throw-out collar 193 is in contact with 195 top surface of sliding block, type core throw-out collar 193 will be pushed
Sliding block 195 moves down, at this time left side core sliding block 3 and right side core sliding block 24 will under the action of pull rod 194 simultaneously to
Interior mobile completion side core-pulling, when the bottom of stop nut 21, which is moved to, to be in contact with moving template 6, drag hook bar 16 is combined in protruding pin
It protruding pin bar 173 in device 17 and rotation and breaks off relations counterclockwise with hook pin 18 under the barrier effect of roller 174, therefore, moving template 6
It will be moved downwardly together under the action of stop nut 21 with dynamic model part with cavity plate 2, after being moved to certain distance, top
Bar 27 will push plastic 26 to release from cavity plate 2, complete demoulding work.
Working principle: when die sinking, for mold from die joint parting, solid plate 1 is motionless (due to the gib head 161 in drag hook bar 16
Part contacts with each other with hook pin 18, so cavity plate 2 and moving template 6 are also fixed)；Type core bar fixed plate 7, the support of type core bar
Plate 8, backing plate 9 and Bottom clamp plate 12 retreat together under the action of injector, due to studs 20 and 7 spiral shell of type core bar fixed plate
Line connection, so studs 20 also and then moves down；It is fixed since the type core bar 192 of type core bar group 19 is fixed on type core bar
Between plate 7 and type core bar support plate 8, so type core bar 192 also and then moves down, when type core throw-out collar 193 and 195 top surface of sliding block
When being in contact, type core throw-out collar 193 will push sliding block 195 to move down, and left side core sliding block 3 and right side core sliding block 24 will at this time
It can be moved inward simultaneously under the action of pull rod 194 and complete side core-pulling, when the bottom of stop nut 21 is moved to and 6 phase of moving template
When contact, drag hook bar 16 rotates simultaneously counterclockwise under the barrier effect of protruding pin bar 173 and roller 174 in protruding pin combination unit 17
Break off relations with hook pin 18, therefore, moving template 6 and cavity plate 2 will under the action of stop nut 21 and dynamic model part downwardly together
Mobile, after being moved to certain distance, mandril 27 will push plastic 26 to release from cavity plate 2, complete demoulding work；
When joint transfer stop nut 21 and when corresponding 173 position of protruding pin bar can reach adjusting side core-pulling away from.Specifically
It is as follows, if rotary stopper nut 21 moves it up side core-pulling away from tuning up, while rotating protruding pin group and attaching together
The shaft 172 for setting 17, makes protruding pin bar 173 also move up same distance, this purpose is that synchronizing relay drag hook bar 16 is counterclockwise
The time of rotation, such side core-pulling is away from becoming larger；Similarly, if side core-pulling away from turning down, opposite direction rotary stopper
Nut 21 moves down it, while rotating the shaft 172 of protruding pin combination unit 17, moves down protruding pin bar 173 similarly
Distance, this purpose are to tail off the time for rotating counterclockwise drag hook bar 16, and such side core-pulling is away from becoming smaller, since type core pushes away
The distance of ring 193 to sliding block 195 determines the time of delay side core-pulling, as long as so adjustment type core throw-out collar 193 and sliding block 195
Distance can be achieved with the adjusting of delay side core-pulling time, and concrete operations are as follows: in the case where meeting type core bar 19 core pulling of group, rotation
Make the transition core throw-out collar 193, moves down it, reduces the time of delay side core-pulling at this time；Similarly, opposite direction rotating core pushes away
Ring 193, moves it up, and increases the time of delay side core-pulling at this time.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
