Description
Technical field
The present invention relates to mold ejection mechanism field, the more particularly to double-deck ejector retainner plate secondary ejecting mechanism of mould.
Background technology
With the continuous improvement of technology, the fast development of plastic cement products industry, the diversification structure of all kinds of plastic cement parts
Become increasingly complex, quality requirements are more and more strict, also more and more high to plastic cement products industry requirement, competition is also more and more fierce,
How to ensure that similar plastic cement products occur without exception in process of production, maximized guarantee Product processing is effective, stabilization
Production cycle, in ejection process, easily appearance top is convex, and deformation, cool time is long, has influence on product quality and production efficiency is asked
Topic.What present plastic cement industry ejecting mechanism was is all dome pin, flat thimble, silk tin, oblique top, and traditional ejection is all once
, many product glue positions and muscle position are relatively deep, and thimble is relatively more, and many glue position muscle positions of product are also in thimble when product is ejected
Clipped between thimble, the problem of some are even many same, cause product to eject and be also difficult to take out inside thimble after die,
Even if can take out, imbalance causes thimble to be damaged when also can be because taking out, scratch product, increases bad, cost of idleness.
The content of the invention
In order to solve the above technical problems, the invention provides the double-deck ejector retainner plate secondary ejecting mechanism of mould.
The technical solution adopted for the present invention to solve the technical problems is：Mould bilayer ejector retainner plate secondary ejecting mechanism, it
Including rear pattern plate, bottom plate, lower ejector retainner plate, upper ejector retainner plate and push rod；The downside of described lower ejector retainner plate and bottom plate
Upper contact；The downside of described upper ejector retainner plate and the upper contact of lower ejector retainner plate；Worn above and below the right-hand member of described upper ejector retainner plate
Provided with limited post；Distance is left with rear pattern plate in the top of described limited post after passing through upper ejector retainner plate；The bottom of described limited post
End is bolted on lower ejector retainner plate；Spring strut is equipped with described bottom plate；Insert on the top of described spring strut
In lower ejector retainner plate；Described spring strut is internally provided with spring and bolt；Described bolt is through spring and bolt
The bottom connection of nut and spring, the spiral shell handle of bolt are fixed after passing spring strut and lower ejector retainner plate with upper ejector retainner plate；Described top
Bar is fixed through bottom plate and lower ejector retainner plate and with upper ejector retainner plate from bottom to up.
Operation principle：Push rod is moved upwards, and ejector retainner plate is moved upwards with upper thimble in promotion；Now, due to spring strut
The effect of internal spring so that lower ejector retainner plate is close to ejector retainner plate and moved upwards with lower thimble；Limited post is also with lower top
Needle plate is moved upwards, when the top of limited post is contacted with the bottom of rear pattern plate, and lower ejector retainner plate stops due to the effect of limited post
Motion upwards；Now, push rod is continued up, and upper ejector retainner plate is continued up and separated with lower ejector retainner plate until upper thimble
Plate is contacted with the bottom of rear pattern plate, that is, completes Double-ejection；When once ejecting, whole thimbles of upper thimble and lower thimble are by product
Ejection；During Double-ejection, product is ejected from accounting on large number of lower thimble by accounting for the upper thimble of smaller amount, product is
It can automatically drop, also can easily remove, improve efficiency, save cost.
Beneficial effects of the present invention：The double-deck ejector retainner plate secondary ejecting mechanism of mould of the present invention, using passing through brute spring
Two groups of ejector retainner plates are fixed, then by spacing two groups of ejector retainner plates of post separation, product is first ejected die, then pass through smallest number
Thimble ejects product from the thimble of big quantity, product is automatically dropped or is easily removed, product ejection process is accurately steady
It is fixed, the ejection efficiency of product is considerably increased, the ejection quality of product is improved, cost is saved.
Brief description of the drawings
Fig. 1 is the schematic diagram of the double-deck ejector retainner plate secondary ejecting mechanism of mould of embodiment；
Fig. 2 ejects the schematic diagram of state for the first time of the double-deck ejector retainner plate secondary ejecting mechanism of mould of embodiment；
Fig. 3 is the schematic diagram of second of ejection state of the double-deck ejector retainner plate secondary ejecting mechanism of mould of embodiment；
Wherein, ejector retainner plate under 1- rear pattern plates, 2- bottom plates, 3-, the upper ejector retainner plates of 4-, 5- limited posts, 6- spring struts, 7- bullets
Thimble under spring, 8- push rods, 9- bolts, 31-, the upper thimbles of 41-.
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, protection scope of the present invention is not constituted and limited.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, the double-deck ejector retainner plate secondary ejecting mechanism of mould, it includes rear pattern plate 1, bottom plate
2nd, lower ejector retainner plate 3, upper ejector retainner plate 4 and push rod 8；The downside of described lower ejector retainner plate 3 and the upper contact of bottom plate 2；It is described
Upper ejector retainner plate 4 downside and lower ejector retainner plate 3 upper contact；Limited post is equipped with above and below the right-hand member of described upper ejector retainner plate 4
5；Distance is left with rear pattern plate 1 in the top of described limited post 5 after passing through upper ejector retainner plate 4；The bottom of described limited post 5 passes through
It is bolted on lower ejector retainner plate 3；Spring strut 6 is equipped with described bottom plate 2；The top of described spring strut 6 is inserted in
In lower ejector retainner plate 3；Described spring strut 6 is internally provided with spring 7 and bolt 9；Described bolt 9 passes through spring 7 and spiral shell
The nut of bolt 9 is connected with the bottom of spring 7, the spiral shell handle of bolt 9 passes spring strut 6 and lower ejector retainner plate 3 after it is solid with upper ejector retainner plate 4
It is fixed；Described push rod 8 is fixed through bottom plate and lower ejector retainner plate 3 and with upper ejector retainner plate 4 from bottom to up.
The operation principle of the double-deck ejector retainner plate secondary ejecting mechanism of the mould of the present embodiment：Push rod 8 is moved upwards, is pushed up in promotion
Needle plate 4 is moved upwards with upper thimble 41；Now, due to the effect of the spring 7 inside spring strut 6 so that lower ejector retainner plate 3 is close to
Upper ejector retainner plate 4 is moved upwards with lower thimble 31；Limited post 5 is moved upwards also with lower ejector retainner plate 3, treats the top of limited post 5
When being contacted with the bottom of rear pattern plate 1, lower ejector retainner plate 3 stops upward motion due to the effect of limited post 5；Now, push rod 8 continue to
Upper motion, upper ejector retainner plate 4 is continued up and separated with lower ejector retainner plate 3 until the bottom of upper ejector retainner plate 4 and rear pattern plate 1 connects
Touch, that is, complete Double-ejection；When once ejecting, whole thimbles of upper thimble 41 and lower thimble 31 eject product；Double-ejection
When, product can be fallen automatically from ejection on large number of lower thimble 31, product is accounted for by the upper thimble 41 for accounting for smaller amount
Fall, also can easily remove, improve efficiency, save cost.
Above-described embodiment should not in any way limit the present invention, all to be obtained by the way of equivalent or equivalency transform
Technical scheme all fall within protection scope of the present invention.
