Lower ejector retainner plate and thimble, arrange core on support block, have die cavity between core and die cavity, have the working of plastics of injection mo(u)lding in die cavity,
Thimble is contacted through core with working of plastics, it is characterised in that：Installing hole is formed with described die cavity, platform in installing hole, is formed with
Rank, arranges push rod in installing hole, baffle plate is formed with push rod, and baffle plate lower end is engaged with step, and elastic plastic, push rod are arranged on baffle plate
Outer wall on be formed with into compression, air inlet is formed with die cavity, air inlet is communicated with compression is entered, under the air inlet annular groove
There is air inlet gap between the push rod and die cavity in portion, outside atmosphere Jing air inlet, enter compression and air inlet gap and mould cavity.
The invention discloses a kind of antiseized mold mechanism in molding mold cavity side, after working of plastics injection mo(u)lding, mould is from type
Gradually mold at core and die cavity, while mould is opened, elastic plastic downwardly against working of plastics, makes modeling in the presence of restoring force
Materials and parts are always maintained at contacting with core, and working of plastics is separated with die cavity, and while outside air is entered by air inlet
In compression, then by compression Jing air inlet gaps are entered in die cavity, working of plastics is made to be easier to separate with die cavity, it is to avoid working of plastics
Negative pressure and adhesion are produced between die cavity, makes working of plastics follow core to mold together, after mould is molded completely, by injector
Push rod withstands lower ejector retainner plate through through hole, and upper and lower ejector retainner plate drives thimble upwards, ejects working of plastics by thimble take off from core
Mould.The antiseized mold mechanism in this programme molding mold cavity side, by arranging push rod and elastic plastic in die cavity side, using elastic plastic
Drive push rod to push down on working of plastics and separate with die cavity when elastic force molds mould, and with reference to air inlet, enter compression and enter
Gas gap admits air into die cavity, it is to avoid negative pressure is produced between working of plastics and die cavity, enables working of plastics to follow core downwardly together,
Ensure that working of plastics finally can the smoothly demoulding.
The antiseized mold mechanism in molding mold cavity side of the present invention, is formed with jack in described working of plastics, is formed with slotting under push rod
Bar, inserted link are contacted through jack with core.Contacted with core by inserted link, one side mould can be pushed away by core in matched moulds
Dynamic inserted link resets, and on the other hand avoids elastic plastic elastic force from crossing senior general's push rod in mold-closing injection and is pressed downward, makes the modeling of injection mo(u)lding
Gravure is formed on materials and parts.
