Part, thimble is in contact through core with working of plastics, it is characterised in that：It is formed with mounting hole, mounting hole and is formed with described die cavity
Set in step, mounting hole and baffle plate is formed with push rod, push rod, baffle plate lower end is engaged with step, and elastic plastic is set on baffle plate, is pushed away
It is formed with the outer wall of bar into compression, air admission hole is formed with die cavity, air admission hole is communicated with entering compression, positioned at air inlet annular groove
Have air inlet gap between the push rod and die cavity of bottom, outside atmosphere through air admission hole, enter compression and air inlet gap and mould cavity.
The utility model discloses a kind of anti-sticking mold mechanism in molding mold cavity side, after working of plastics injection molding, mould
Gradually molded at core and die cavity, while mould is opened, elastic plastic in the presence of restoring force downwardly against working of plastics,
Make working of plastics be always maintained at being in contact with core, and working of plastics is separated with die cavity, and outside air is entered by air admission hole simultaneously
Enter into compression, then entered by entering compression through air inlet gap in die cavity, make working of plastics be easier to separate with die cavity, it is to avoid modeling
Negative pressure and adhesion are produced between materials and parts and die cavity, makes working of plastics follow core to mold together, after mould is molded completely, by injecting
The push rod of machine withstands lower ejector retainner plate through through hole, and upper and lower ejector retainner plate drives thimble upwards, is pushed up from core working of plastics by thimble
Go out the demoulding.The anti-sticking mold mechanism in this programme molding mold cavity side, by setting push rod and elastic plastic in die cavity side, utilizes elastic force
Drive push rod to push down on working of plastics when the elastic force of glue molds mould to separate with die cavity, and combine air admission hole, enter compression
Die cavity is admitted air into air inlet gap, it is to avoid negative pressure is produced between working of plastics and die cavity, working of plastics is followed core together
Downwards, it is ensured that working of plastics finally can be smoothly stripped.
Jack is formed with the anti-sticking mold mechanism in the utility model molding mold cavity side, described working of plastics, is made under push rod
There is inserted link, inserted link is in contact through jack with core.Contacted by inserted link with core, one side mould can pass through type in matched moulds
Core promotes inserted link to reset, and on the other hand avoids elastic plastic elastic force to cross senior general's push rod in mold-closing injection and is pressed downward, makes injection molding
Working of plastics on form gravure.

Embodiment
The utility model is related to a kind of anti-sticking mold mechanism in molding mold cavity side, as shown in Fig. 1-Fig. 4, including upper compound plate 1
With lower compound plate 2, set under upper compound plate in die cavity 3, lower compound plate under being provided with through hole 4, lower compound plate between setting support block 5, support block
Upper ejector retainner plate 6, lower ejector retainner plate 7 and thimble 8 are set on compound plate, and the push rod 22 of injector is in contact through through hole with lower ejector retainner plate,
Core 9 is set on support block, there is the working of plastics 11 for having injection molding in die cavity 10, die cavity, thimble pass-through between core and die cavity
Core 9 is in contact with working of plastics, it is characterised in that：It is formed with described die cavity 3 in mounting hole 13, mounting hole and is formed with step 14, is pacified
