Description
Technical field
Plastic tray injection mold is the utility model is related to, more particularly to plastic tray injection mold side core-pulling mechanism.
Background technology
In the storages and logistics progress such as various medicine foods, plastics chemical industry, raw material, it usually needs use plastic tray
Disk.In order that the intensity of plastic pallet is high, and and can saves material, and neat interval row can be all formed with the upper surface of plastic pallet
The square groove or square hole of row, the main body of pallet is formed by reinforcement between square groove, disk pin is formed with pallet, is had between disk pin slotting
Hole, bottom plate is formed with jack, the insert that injection mold is located in jack then can not directly carry out core pulling, but will be first by insert
Under side action sliders extract out, then insert gradually glides further along the inclined-plane of side action sliders, make insert deviate from plastic pallet
Square groove and reinforcement, be finally stripped again.But the side action sliders of existing injection mold are when extracting out, only by plastic pallet
Under reinforcement to insert carry out it is spacing, driven after reinforcement and square groove is sliding out under insert is gradual, then by side action sliders
Insert extracts the jack of plastic pallet out together, and spacing due to being carried out by the reinforcement under plastic pallet, side action sliders are being drawn
When going out, easily drive insert to skid off together, cause reinforcement to deform, so as to cause whole pallet to be scrapped, the yield rate of product is low.
The content of the invention
The shortcomings that the purpose of this utility model is to overcome prior art to exist, there is provided one kind makes plastic pallet smoothly take out
Core is simultaneously stripped, the high yield rate of product, ensures the plastic tray injection mold side core-pulling mechanism of product quality.
The technical scheme of the utility model plastic tray injection mold side core-pulling mechanism is：Including upper compound plate and lower compound plate,

Pin, upper and lower ejector retainner plate are driven through oil cylinder, and core is set on support block, the plastic pallet for having injection molding between core and die cavity, top
Pin is in contact through core with plastic pallet, and reinforcement and square groove are formed with plastic pallet lower surface, disk is formed with plastic pallet
Pin, jack is formed between disk pin, has bottom plate under jack, it is characterised in that：The side of the core sets side to pump cylinder, on core
Side action sliders are set, the piston rod of side oil pumping cylinder is connected with side action sliders, and slider guide is set on the inside of side action sliders,
Slider guide is engaged with the plastic pallet lower end reinforcement at jack, and inclined guide groove, slider guide are formed with side action sliders
Lower end be engaged with inclined guide groove, spacing block is set in the medial end of side action sliders, is formed with locating slot under slider guide, it is fixed
Position groove is in contact with spacing block, and mounting groove is provided with core side wall, and installation notch set limited block, limited block through fastener and
Core is mutually fixed, and pulling block is set on the inside of slider guide, and pulling block is in contact with limited block inwall.
The utility model discloses a kind of plastic tray injection mold side core-pulling mechanism, after plastic pallet injection molding,
Mould molds, and side oil pumping cylinder drives side action sliders to move outward, and the inclined guide groove in side action sliders matches with slider guide lower end
Close, slider guide is moved reinforcement and square groove that abjection plastic pallet is located at jack gradually downward along inclined guide groove, due to leading
The inner side of sliding block sets pulling block, and pulling block coordinates with the limited block in core side wall mounting groove, makes slider guide be only capable of moving down, and
Can not be moved outward with side action sliders, and when side action sliders move outward, until its medial end spacing block with
When the locating slot of slider guide is in contact, spacing block blocks the locating slot of slider guide, at the same slider guide also drive pulling block gradually to
Under, and pulling block is disengaged with limited block, now side action sliders drive slider guide to be moved to the outside together, deviate from both
The jack of plastic pallet, upper and lower ejector retainner plate is driven to move up finally by power such as oil cylinders, upper and lower ejector retainner plate drives thimble
By the plastic pallet ejection device of injection molding.This programme plastic tray injection mold side core-pulling mechanism, by the inside of slider guide
Pulling block and core in limited block coordinate, make side action sliders when moving outward slider guide will not be driven to move outward together
It is dynamic, so as to avoid drawing the reinforcement under bad plastic pallet, make the smooth core pulling of plastic pallet and be stripped, ensure the quality of product, produce
The high yield rate of product.
The utility model plastic tray injection mold side core-pulling mechanism, the outer wall of the side action sliders are formed with outer inclined-plane,
Latch segment is formed with the outside of die cavity, latch segment inwall is formed with outer inclined-plane, and outer inclined-plane is engaged with outer inclined-plane.There is latch segment, increase
Add the coupling mechanism force to side action sliders.
