Abstract
The invention discloses a device for two-stage ejection and forcible stripping of a snap joint. The device comprises a mold core A plate, a mold core B plate, a baseplate, an elastic pin and a plastic part push rod, wherein the upper part of the mold core B plate is connected to the mold core A plate, and the lower part of the mold core B plate is arranged on the baseplate; the plastic part push rod passes through the baseplate and is connected to an ejector plate; the ejector plate is arranged on the baseplate and in the mold core B plate; a return pin spring is arranged between the ejector plate and the mold core A plate; and one end of the elastic pin passes through the mold core A plate and is connected to the snap joint, and the other end of the elastic pin passes through the ejector plate and is connected to the baseplate. The device has the beneficial effects that the snap joint with elastic deformation is forcibly stripped by using the elastic pin, and the device is simple in structure, reliable in performances, convenient to use and easy to maintain in later period and meanwhile has a very good using effect on molding of a snap joint structure in a plastic injection mold.
Description
Technical field
The present invention relates to technical field of mold, particularly relate to a kind of device taking off by force buckle for Double-ejection.
Background technology
There is a lot of plastic according to the requirement of its actual serviceability in daily life and industrial production, have a lot of elastic-buckle structure.For this type of buckle structure, be all adopt traditional method at Many times, extract button bit out with core-pulling mechanism.The cooperation between each mechanism, motion sequencing, spacing guiding to be considered when using traditional core-pulling mechanism and penetrate pressure to prevent from retreating.Obvious increase mechanism complexity, consumes too large cost, makes troubles also to the maintenance in later stage.
Summary of the invention
For the deficiency that prior art exists, object of the present invention just there are provided a kind of device taking off by force buckle for Double-ejection, bullet pin formal compulsion is utilized to deviate to have elastically-deformable buckle, structure is simple, dependable performance, easy to use, later stage maintenance is easy, and in plastic injection mold, shaping buckle structure has good result of use simultaneously.
To achieve these goals, the technical solution used in the present invention is such: a kind of device taking off by force buckle for Double-ejection, comprise die A plate, die B plate, base plate, bullet pin, plastic push rod, the top of described die B plate is connected with die A plate, bottom is arranged on base plate; Described plastic push rod is connected with ejector retainner plate through base plate, and described ejector retainner plate to be positioned on base plate and to be arranged at die B plate, and is provided with back stitching spring between ejector retainner plate and die A plate; One end of described bullet pin is connected with buckle through die A plate, and the other end playing pin is connected with base plate through ejector retainner plate.
As a kind of preferred version, described bullet pin is provided with thimble near one end of die A plate, and the top of described thimble is connected with buckle.
As a kind of preferred version, described bullet pin is provided with spacing limited screw near one end of base plate, and described spacing limited screw bottom is arranged in base plate.
As a kind of preferred version, the spacing distance of described spacing limited screw is greater than the height of buckle.
As a kind of preferred version, also comprise back stitching spring fixed bar, one end of described back stitching spring fixed bar is connected with die A plate, the other end is connected with base plate through ejector retainner plate, and described back stitching spring housing is located at outside back stitching spring fixed bar.
Compared with prior art, beneficial effect of the present invention: the present invention utilizes bullet pin formal compulsion to deviate to have elastically-deformable buckle, and structure is simple, dependable performance, easy to use, later stage maintenance is easy, and in plastic injection mold, shaping buckle structure has good result of use simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Embodiment:
As shown in Figure 1, a kind of device taking off by force buckle for Double-ejection, comprise die A plate 1, die B plate 2, base plate 3, play pin 4, plastic push rod 5, the top of described die B plate 2 is connected with die A plate 1, bottom is arranged on base plate 3; Described plastic push rod 5 is connected with ejector retainner plate 6 through base plate 3, and described ejector retainner plate 6 to be positioned on base plate 3 and to be arranged at die B plate 2, and is provided with back stitching spring 7 between ejector retainner plate 6 and die A plate 1; One end of described bullet pin 4 is connected with buckle 8 through die A plate 1, and the other end playing pin 4 is connected with base plate 3 through ejector retainner plate 6; Described bullet pin 4 is provided with thimble 41 near one end of die A plate 1, and the top of described thimble 41 is connected with buckle 8; Described bullet pin 4 is provided with spacing limited screw 42 near one end of base plate 3, and described spacing limited screw 42 bottom is arranged in base plate 3; The spacing distance of described spacing limited screw 42 is greater than the height of buckle 8; Also comprise back stitching spring fixed bar 9, one end of described back stitching spring fixed bar 9 is connected with die A plate 1, the other end is connected with base plate 3 through ejector retainner plate 6, and described back stitching spring 7 is sheathed on outside back stitching spring fixed bar 9.During concrete enforcement, described buckle 8 is mainly used for assembling, flexible deformation, larger to the flexibility of dimensional requirement, before and after after mold injection pressurize completes, mould is opened, then pickup is ejected, in the process ejected, ejector retainner plate 6 ejects forward by the effect of plastic push rod 5 thrust, all the ejecting together with accessory comprising thimble 41 and bullet pin 4 is driven to eject forward together, at this moment back stitching spring 7 forced compression of ejector retainner plate 6, wherein spacing limited screw 42 limits the ejection stroke playing pin 4, this section of spacing distance is greater than the height of buckle 8, so eject completely when playing the buckle 8 of plastic after pin 4 ejects range line, outside at die, at this moment ejector retainner plate 6 drives thimble 41 to continue stressed ejecting, bullet pin 4 keeps motionless and still hauls buckle 8, thimble 41 just can be forced plastic to eject, and then make the buckle Final 8 system of plastic depart from bullet pin 4.During matched moulds, plastic push rod 5 is recalled, the ejector retainner plate 6 of compressive state makes back stitching spring 7 elastic deformation, complementary rebounds ejector retainner plate 6, during complete matched moulds, back stitching spring 8 is pressed onto position ejector retainner plate 6 under die A plate 1 pressure, play pin 4 also to reset under the pressure of ejector retainner plate 6, then just can start to enter next injection cycle.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
