Abstract
The utility model discloses pulling block after a kind of mould, which includes block-shaped body, and the center of the block-shaped body is provided with drawing pin hole, and the drawing pin hole is provided with internal thread, and the block-shaped body is provided with the installing component for being connected with ejector retainner plate；The utility model clever structure, rationally, is fixed on thimble back by installing component, after the completion of ejection demoulding, while ejector retainner plate push rod is return, in the case where the linkage effect of pin is drawn, ejector retainner plate is accordingly pulled to return original position by block-shaped body, so as to realize the purpose of thimble fast retractile, avoid the occurrence of the phenomenon that core rod or mold damage are hindered in thimble top, it is ensured that normal matched moulds production, it is ensured that product quality, other overall simple, it is easily achieved, low cost, beneficial to being widely popularized.
Description
Technical field
The utility model is related to die ejector pin resetting technique field, and in particular to pulling block after a kind of mould.
Background technology
Mould is indispensable important equipment in injection mo(u)lding.Injection mo(u)lding is by the plastic material high speed of hot melt state
Be injected into there is the closed molding space of required form in mould, after waiting plastic material cooling and solidifying, opening mould will be solid
The plastic cement machining object ejection of change, the method to obtain products formed.As injection molding forming method has, shaping expense is low, molding cycle
The features such as short, forming process is simple and is easy to the plastic cement products of forming shape complexity, therefore in plastic cement products manufacture field application
It is extremely widespread.
Generally, in die sinking, i.e., when caster and male template separate, product is just ejected by thimble immediately, complete
Completely without time delay.And in matched moulds, thimble need to be retracted in advance, to avoid thimble top from hindering core rod；Usual method is to be equipped with pressing, should
Pressing is protruded from the land area of male template and height is higher than thimble, is made in pressing by the matched moulds elder generation top pressure of caster and male template
Ejector retainner plate is retreated and then makes thimble retract, and closure pressing speed is too fast or mould long-time is contracted using easily occurring thimble after abrasion sometimes
Phenomenon not in place is returned, so as to cause top to hinder core rod or mold damage so that product is unqualified, when serious, can cause the mould cannot
Production.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, there is provided a kind of clever structure, rationally, in matched moulds, effectively
Guarantee pulling block after the mould that thimble is return in place.
For achieving the above object, technical scheme provided by the utility model is：Pulling block after a kind of mould, which includes bulk
Body, the center of the block-shaped body are provided with drawing pin hole, and the drawing pin hole is provided with internal thread, and the block-shaped body is provided with use
Come the installing component being connected with ejector retainner plate.
Used as a kind of improvement of the present utility model, the installing component is included lock screw and is adapted with the lock screw
Installing hole, multiple installing holes to draw pin hole to be symmetricly set in the center of circle on the block-shaped body as the center of circle, and in the thimble
Plate is provided with positive screw hole relative with the installing hole.
Used as a kind of improvement of the present utility model, the quantity of the installing hole is four.
Used as a kind of improvement of the present utility model, the cross section of the block-shaped body is circle.
Used as a kind of improvement of the present utility model, the rear end face of the block-shaped body is provided with wearing layer.
The beneficial effects of the utility model are：The utility model clever structure, rationally, is fixed on thimble by installing component
Back, after the completion of ejection demoulding, while ejector retainner plate push rod is return, in the case where the linkage effect of pin is drawn, by block-shaped body
It is corresponding to pull ejector retainner plate to return original position, so as to realize the purpose of thimble fast retractile, it is to avoid thimble top occur and hinder core rod or damage
The phenomenon of mould, it is ensured that normal matched moulds is produced, it is ensured that product quality, in addition overall simple, it is easy to accomplish, low cost, beneficial to wide
General popularization.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Pulling block after a kind of mould provided referring to Fig. 1, the present embodiment, which includes block-shaped body 1, in the block-shaped body 1
Heart position is provided with drawing pin hole 2, and the drawing pin hole 2 is provided with internal thread, and the block-shaped body 1 is provided with for being connected with ejector retainner plate 6
The installing component for connecing.Specifically, the installing hole 4 that the installing component is included lock screw 3 and is adapted with the lock screw 3 is more
Individual installing hole 4 is to draw pin hole 2 to be symmetricly set in the center of circle on the block-shaped body 1 as the center of circle, and is provided with the ejector retainner plate 6
Positive screw hole 5 relative with the installing hole 4.Preferably, be also provided with the back side of ejector retainner plate 6 mutually fitting with the block-shaped body 1
The installation recess 7 matched somebody with somebody, fast and easy are accurately positioned installation.
In the present embodiment, the quantity of the installing hole 4 is four, and in other embodiments, the quantity of the installing hole 4 can be
Three, five or more.
For convenience of processing and fabricating, the cross section of the block-shaped body 1 is circle, and good looking appearance, practicality are good.Make to extend
With the life-span, wearing layer is provided with the rear end face of the block-shaped body 1.
During use, drawing pin 9 is installed on ejector retainner plate push rod 8, one end of the drawing pin 9 is screwed into drawing pin hole 2, realizes and bulk
The purpose that body 1 is connected；And block-shaped body 1 is arranged on 6 back side of ejector retainner plate by installing component, after die sinking, ejector retainner plate push rod 8
Top pressure on block-shaped body 1 forces ejector retainner plate 6 to promote thimble 10 to move ahead and realizes the purpose of ejection demoulding；After the completion of ejection demoulding,
While ejector retainner plate push rod 8 is return, in the case where the linkage effect of pin 9 is drawn, ejector retainner plate is pulled to return original by block-shaped body 1 is corresponding
Position, realizes the purpose of 10 fast retractile of thimble, it is to avoid the phenomenon that core rod or mold damage are hindered in thimble top occur.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and is changed.Therefore, the utility model is not limited to specific embodiment disclosed and described above, right
