And thimble, fixed plate is set on support block, core and side action sliders are set in fixed plate, side action sliders are pumped cylinder band through side
It is dynamic, there is the plastic pallet of injection molding between core and die cavity, be formed with disk pin under plastic pallet, prong is provided with disk pin, mould
Material torr disk, which is located above prong, is formed with grid hole, and interior oblique surface and outer oblique surface are formed with disk pin, it is characterised in that：Described side
Oblique guide hole is provided with core-pulling slide block, inclined guide is set in oblique guide hole, the interior oblique surface side that inclined guide is located at disk pin is formed with vertically
Downward barb, barb are in contact with interior oblique surface, and the other end of inclined guide is formed with connecting rod, the inclination of connecting rod and inclined guide
Angle is consistent, and the external diameter of connecting rod is less than inclined guide, and the side that connecting rod is located in oblique guide hole sets baffle plate, and connecting rod passes through
Baffle plate connects spacing arm-tie, is externally provided with spring in connecting rod, spring side is in contact with inclined guide, spring opposite side and baffle plate phase
Contact.
The invention discloses barb demoulding mechanism in a kind of plastic tray injection mold side, it is mainly characterized by side core-pulling
Oblique guide hole is provided with sliding block, inclined guide, a barb being formed with vertically downward of inclined guide, barb and disk pin are set in oblique guide hole
Interior oblique surface be in contact, the other end of inclined guide is formed with connecting rod, and connecting rod is connected through baffle plate with spacing arm-tie, connection
Bar be located at baffle plate inner side set spring, after plastic pallet injection molding, first by lower compound plate drive support block, upper ejector retainner plate, under
Ejector retainner plate, fixed plate, core, side action sliders, side oil pumping cylinder, plastic pallet move downwardly together, die cavity is first deviate from plastics
Grid hole on the disk pin of pallet, the outside Slideslip of side action sliders is then driven by side oil pumping cylinder, in the work of spring thrust
Under, side action sliders although outside Slideslip, and inclined guide is then withstood in the side wall of core always, and inclined guide is along tiltedly leading
The incline direction in hole moves up, so that the interior oblique surface of the gradual prolapse upwards disk pin of inclined guide, until spacing arm-tie and gear
Plate is in contact, and baffle plate is spacing to the progress of spacing arm-tie, it is not continued to move to, and spacing arm-tie enters to connecting rod and inclined guide
Row is spacing, now the barb also interior oblique surface of prolapse upwards disk pin, and side action sliders, tiltedly are driven finally by side oil pumping cylinder
Guide rod and barb are displaced outwardly extracting out together the prong of disk pin, drive thimble upwards to eject plastic pallet by upper and lower ejector retainner plate
The demoulding.Barb demoulding mechanism in this programme plastic tray injection mold side, using opening oblique guide hole in side action sliders with tiltedly leading
Bar coordinates, and in a barb being formed with vertically downward of inclined guide, inclined guide other end passes through spacing arm-tie, baffle plate and spring
Cooperation, side action sliders make the interior oblique surface of barb abjection disk pin while side core-pulling, another to act the fork for extracting disk pin out
Mouthful, the time of core pulling is not take up, improves production efficiency, simple in construction, the demoulding is smooth.
Barb demoulding mechanism in plastic tray injection mold side of the present invention, slide rail is formed with described fixed plate, side is taken out
Core sliding block lower end is engaged with slide rail.There is slide rail, guide effect is played to moving left and right for side action sliders, slides side core-pulling
Block slip is smooth, and it is accurate to be oriented to.
