The invention discloses a kind of three-level slide block demolding mechanisms with wide-angle back-off mold, when demoulding, by injection molding machine
Power driven mold moving template and solid plate are opened, and inclined guide is moved being delayed in oblique guide hole, do not drive outer slide first, but
It is opened under power drive, collision block is separated with clamping block, and under the action of the spring, and mounting hole insert is driven to take off from mounting hole
Out, continue to be opened, inclined guide continues to move to encounter the hole wall for the oblique guide hole that is delayed, and outer slide is driven to slide in and out, and outer slide drives
Inner slide slides in and out, and under the effect of the oblique chute of interior slider head, makes to be buckled to insert with mounting hole insert together along oblique
The outside slide downward of sliding slot, deviates from from back-off, and back-off and mounting hole demoulding are completed, and is further continued for die sinking to terminating, by injection molding machine
Powered lower roof plate and upper plate, upper plate drive mandril by outside product ejection die, and product stripping is completed.This programme uses
Delay, bullet block and oblique sliding three-level stripping structure, realize that back-off and mounting hole are smoothly deviate from, compact-sized, ingenious in design, by being opened
Power and spring drive, and without separately setting oil cylinder, cost is saved, and act smooth, high production efficiency.
Three-level slide block demolding mechanism with wide-angle back-off mold of the invention, the back-off insert periphery setting stop
Position block, stop block are fixed in moving template, and clamping block passes through stop block and is in contact with collision block outer wall, there is stop block, Ke Yiyou
Effect prevents back-off insert from rising mould.

Specific embodiment
The present invention relates to a kind of three-level slide block demolding mechanisms with wide-angle back-off mold, as shown in Fig. 1-Fig. 3, packet
Compound plate 1 and lower compound plate 2 on mold are included, hot flow path bracket 3 is installed under upper compound plate, solid plate 4, hot flow path are installed under hot flow path bracket
Hot mouth 5 is connected in bracket, and support block 6 is installed on lower compound plate, lower roof plate 7 and upper plate 8 are set between support block, dynamic model is installed on support block
Plate 9, the gap between moving template and solid plate constitute die cavity 10, and hot mouth 5 passes through solid plate 4 and is connected to die cavity 10, is molded in die cavity
The one side edge setting of product 11, product is buckled to 12, and mounting hole 13 is formed in back-off, connects mandril 15, mandril 15 on upper plate 8
It is in contact across moving template 9 with product 11, fixing seat 20 is set on the side outer wall of the support block 6, slides and sets in fixing seat
Outer slide 21 is set, the oblique guide hole 22 of setting delay in outer slide, the inside of outer slide connects inner slide 23, and inner slide protrudes into moving template
In 9, and oblique chute 24 is set on the head of inner slide, oblique connection is buckled to insert 25, back-off insert 25 and back-off in oblique chute
12 match, and the mounting hole insert 26 worn is touched in setting in back-off insert 25, and mounting hole insert 26 is matched with mounting hole 13, peace
Collision block 27 is arranged in the tail portion for filling hole insert 26, and spring 28, cover half corresponding with collision block is arranged between collision block 27 and back-off insert 25
