Abstract
The utility model discloses a kind of secondary ejecting mechanism, including front template, rear pattern plate, preceding mould ejector retainner plate, rear mold thimble plate and rear mold thimble plate pulling block, rear mold thimble plate pulling block one end connection front template, rear mold thimble plate pulling block other end connection rear mold thimble plate.During front and rear mould die sinking motion, rear pattern plate is motionless, and front template motion, rear mold thimble plate pulling block hauls the motion of rear mold thimble plate, and rear mold thimble plate thimble ejecting product, product is viscous to move on preceding mould with together with preceding mould；After front and rear mould die sinking motion terminates, preceding mould ejector retainner plate motion, after moving a certain distance, product ejection, the smoothly demoulding；Mould ejector retainner plate first moves return before during matched moulds, afterwards rear mold thimble plate return, and front and rear mould matched moulds is waited and is molded next time.
Description
Technical field
It the utility model is related to plastic mould field, more particularly to a kind of secondary ejecting mechanism.
Background technology
It is most important how quality that the ejection system of injection mold to plastic cement products be molded is designed.
Generally, finished product is removed from the molds, either using the ejecting mechanism of single or more original papers, it is pushed up
It is all once to complete to go out action, still, because the shape of finished product is special, or requirement during volume production, if after once ejecting,
Finished product still in die cavity, or can not Automatic-falling when, it is necessary to be further added by once ejection action, such ejection action is set
Meter, referred to as Double-ejection.
In Chinese patent literature disclosed " a kind of secondary ejecting mechanism with oblique top ", its notification number is
CN205097475U, the day for announcing are on March 23rd, 2016, and the utility model discloses a kind of secondary ejecting mechanism with oblique top,
Including front template and rear pattern plate, rear pattern plate is provided with the first push pedal, the second push pedal and push rod, and one end of the first push pedal and push rod is fixed
Connection, the first push pedal are provided with oblique top guide rod, and rear pattern plate is further fixed on oblique top mold insert, and the second push pedal is fixed with crowded bar of cutting somebody's hair, push rod
Thimble panel and Ejector Retainer Plate are fixed with, thimble is provided between thimble panel and Ejector Retainer Plate, Ejector Retainer Plate is provided with fixed mold insert,
Fixed mold insert is provided with fixed accommodating hole, and thimble panel is provided with movable insert, and movable insert is located at push rod bottom, and movable insert passes through
Spring is connected with thimble panel, and movable insert is provided with movable accommodating hole.The secondary ejecting mechanism with oblique top can be basic
Double-ejection is realized in the case of not increasing mold thickness, and adapts to small board production, saves production cost.But the reality
Need again to eject product from rear pattern plate after the die sinking of front and rear film with new first time ejection process so that knockout course work
Sequence increase, production efficiency reduce.
Utility model content
The utility model is in order to overcome deficiency of the prior art, there is provided a kind of Double-ejection machine for reducing stripping process
Structure.
To achieve these goals, the utility model uses following technical scheme：
A kind of secondary ejecting mechanism, including front template, rear pattern plate, preceding mould ejector retainner plate, rear mold thimble plate and rear mold thimble plate
Pulling block, rear mold thimble plate pulling block one end connection front template, rear mold thimble plate pulling block other end connection rear mold thimble plate.Front and rear mould is opened
When mould moves, rear pattern plate is motionless, and front template motion, rear mold thimble plate pulling block hauls the motion of rear mold thimble plate, rear mold thimble plate top
Pin ejecting product, product is viscous to move on preceding mould with together with preceding mould；After front and rear mould die sinking motion terminates, preceding mould ejector retainner plate fortune
It is dynamic, after moving a certain distance, product ejection, the smoothly demoulding；Mould ejector retainner plate first moves return before during matched moulds, afterwards rear mold thimble
Plate return, front and rear mould matched moulds are waited and are molded next time.Such structure can make to drive rear mold in front and rear mould die sinking motion process
Ejector retainner plate ejecting product, incorporates process, improves the production efficiency of product.
Preferably, also including preceding mould oil cylinder and rear mould oil cylinder, preceding mould oil cylinder one end is fixedly connected with front template, preceding moulding oil
The cylinder other end is connected with each other by piston rod and preceding mould ejector retainner plate, and rear mould oil cylinder one end is fixedly connected with rear pattern plate, rear mould oil cylinder
The other end is connected with each other by piston rod and rear mold thimble plate.
Preferably, rear mold thimble plate pulling block is provided with the barb for being stuck in rear mold thimble plate bottom.
Preferably, rear pattern plate is provided with the guide groove being oriented to rear mold thimble plate pulling block.
Therefore, the utility model has the advantages that：Merge stripping process, improve production efficiency.
Brief description of the drawings

In figure：1st, front template, 2, rear pattern plate, 3, preceding mould ejector retainner plate, 4, rear mold thimble plate, 5, rear mold thimble plate pulling block, 6,
Preceding mould oil cylinder, 7, rear mould oil cylinder, 8, injecting products, 9, guide groove.
Embodiment
Below by specific embodiment, and with reference to accompanying drawing, the technical solution of the utility model is made more specifically
It is bright.
As shown in figure 1, a kind of non-master stripping direction ejecting mechanism of product, including front template 1, preceding mould oil cylinder 6, preceding mould thimble
Plate 3, rear pattern plate 2, rear mould oil cylinder 7, rear mold thimble plate 4, rear mold thimble plate pulling block 5, preceding one end of mould oil cylinder 6 and front template 1 are fixed
Connection, the preceding other end of mould oil cylinder 6 are connected with each other by piston rod and preceding mould ejector retainner plate 3, and rear one end of mould oil cylinder 7 and rear pattern plate 2 are solid
Fixed connection, the rear other end of mould oil cylinder 7 are connected with each other by piston rod and rear mold thimble plate 4, the connection of the one end of rear mold thimble plate pulling block 5
Front template 1, the other end of rear mold thimble plate pulling block 5 connection rear mold thimble plate 4, rear mold thimble plate pulling block 5 connects rear mold thimble plate 4
One end is provided with the barb being stuck at the bottom margin of rear mold thimble plate 4, and rear pattern plate 2 is provided with and rear mold thimble plate pulling block 5 is led
To guide groove 9.
During front and rear mould die sinking motion, rear pattern plate 2 is motionless, and front template 1 moves, and rear mould oil cylinder 7 acts one with front and rear mould die sinking
Motion is played, rear mold thimble plate pulling block 5 hauls rear mold thimble plate 4 and moved, the thimble of rear mold thimble plate 4 ejection injecting products 8, injection production
