Description
Technical field
The present invention relates to mould ejection field, more particularly to a kind of mould delayed ejector mechanism.
Background technology
When plastic mould product ejects, ejection position, the mechanism of ejection chooses whether suitably, to directly influence the outer of product
See, the cycle of shaping and processing efficiency.Ejecting mechanism decision, need to be depending on the plastic parts structure of guest's product, such as：Product has very
More deep muscle position, or long pillar.Generally in general product our ejectors in the case where not influenceing product appearance size
Structure is all once to eject, and traditional once ejection can be selected.But on some products, product as shown in Figure 1 is using above-mentioned
Traditional ejecting mechanism can not meet the efficiency of requirement and the production of product.Product occurs ejecting product in forming process and is not easy
Take out, when product eject Yi Dingbai at position 9, rise or push up and wear, even if can eject, also to extend cool time, lengthening
Molding cycle, cost of idleness.Influence production efficiency, waste of resource.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of mould delayed ejector mechanism, delayed ejector mechanism is used
Can safe ejecting product, avoid that top is white, and top is worn, improve efficiency, save cost of idleness.
The technical solution adopted for the present invention to solve the technical problems is：A kind of mould delayed ejector mechanism, it includes top
The bottom plate under Ejector Retainer Plate and Ejector Retainer Plate on the downside of needle plate, ejector retainner plate；The outer position of the ejector retainner plate is set
There is push rod；Jacking block is provided with the top of the push rod；The ejector retainner plate is provided with delay thimble close to middle position；It is described
The position of delay thimble on the lower is provided with thimble hanging platform, and counter sink is provided with the Ejector Retainer Plate；The thimble hanging platform is located at
In counter sink, the thimble that delay thimble is located at below thimble hanging platform passes through Ejector Retainer Plate.
When not ejecting state, delay thimble, which is located at after the thimble below thimble hanging platform passes through Ejector Retainer Plate, is against bottom plate
Top surface, the thimble hanging platform is in upper limit.
Delay state, delay thimble position is motionless, and Ejector Retainer Plate moves up, and counter sink moves up, and hangs the thimble of delay thimble
Platform departs from upper limit.
Ejection state, the thimble hanging platform for the thimble that is delayed are in lower limit in counter sink, and Ejector Retainer Plate drives delay thimble
Move up ejection.
Beneficial effects of the present invention：A kind of mould delayed ejector mechanism of the present invention, can be safe using delayed ejector mechanism
Ejecting product, avoid top white, top is worn, and improves efficiency, saves cost of idleness.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of mould delayed ejector mechanism of embodiment；
Fig. 2 is a kind of schematic diagram of the delay state of mould delayed ejector mechanism of embodiment；
Fig. 3 is a kind of schematic diagram of the ejection state of mould delayed ejector mechanism of embodiment.
Embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and examples and further retouched in detail
State, the embodiment is only used for explaining the present invention, and protection scope of the present invention is not formed and limited.
Embodiment
As shown in Figure 1 to Figure 3, a kind of mould delayed ejector mechanism is present embodiments provided, it includes ejector retainner plate 1, thimble
Bottom plate 3 under the Ejector Retainer Plate 2 and Ejector Retainer Plate 2 of the downside of plate 1；The outer position of the ejector retainner plate 1 is provided with top
Bar 4；The top of the push rod 4 is provided with jacking block；The ejector retainner plate 1 is provided with delay thimble 5 close to middle position；It is described
The position of delay thimble 5 on the lower is provided with thimble hanging platform 6, and counter sink 7 is provided with the Ejector Retainer Plate 2；The thimble hanging platform 6
In counter sink 7, the thimble that delay thimble 5 is located at below thimble hanging platform 6 passes through Ejector Retainer Plate 2；When not ejecting state, delay
Thimble 5 is located at the thimble below thimble hanging platform 6 through the top surface that bottom plate is against after Ejector Retainer Plate 2, at the thimble hanging platform 6
In upper limit, i.e. the upper surface of thimble hanging platform 6 offsets with ejector retainner plate 1；Delay state, delay thimble 5 position is motionless, Ejector Retainer Plate
2 move up, and counter sink 7 moves up, and the thimble hanging platform 6 of delay thimble 5 is departed from upper limit；Ejection state, the thimble of delay thimble 5 are hung
Platform 6 is in lower limit in counter sink 7, i.e. the lower surface of thimble hanging platform 6 and the bottom surface of counter sink 7 offsets, and Ejector Retainer Plate 2 drives
Delay thimble 5 moves up ejection.
A kind of mould delayed ejector mechanism of the present embodiment, when product 8 starts ejection, ejector retainner plate moves up, and first drives top
Bar and jacking block ejection, now, delay thimble is motionless；When certain position is moved on ejector retainner plate, the thimble hanging platform for the thimble that is delayed with
The bottom contact of counter sink, delay thimble are driven the ejection for moving up and participating in product；Because it is realized in the form of counter sink
Delay, two pieces of ejector retainner plates return not in place when can avoid doing Double-ejection with mechanical clasps or other structures on the market, and thimble is high, product
Push up convex deformation.
A kind of mould delayed ejector mechanism of the present embodiment, using delayed ejector mechanism can safe ejecting product, avoid pushing up
In vain, top is worn, and improves efficiency, saves cost of idleness.
Above-described embodiment should not in any way limit the present invention, all to be obtained by the way of equivalent substitution or equivalency transform
Technical scheme all fall within protection scope of the present invention.
