Description

A kind of secondary ejecting mechanism of mould
Technical field
It the utility model is related to a kind of mould, and in particular to a kind of secondary ejecting mechanism of mould.
Background technology
Mould, in industrial production being molded, being blow molded, extruding, die casting or obtain the methods of forging forming, smelting, punching press The various moulds and instrument of required product.In brief, mould is the instrument for making formed article, and this instrument is by various Part is formed, and different moulds is made up of different parts.It is mainly realized by the change of institute's moulding material physical state The processing of article profile.It is known as the title of " mother of industry ".Under external force turning into blank has given shape and size The instrument of product.Be widely used in punching, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and engineering plastics, In the forming of compression moulding or the injection of the products such as rubber, ceramics.Mould has specific profile or cavity shape, using with The contour shape of cutting edge can make blank that separation (punching) occur by profile wire shaped.Using cavity shape blank can be made to obtain phase The three-dimensional shape answered.Mould generally comprises two parts of dynamic model and cover half (or punch-pin and cavity plate), and the two is partable.When separating Product is taken out, blank injection mold cavity shaping is made when closing up.Mould is precision instrument, complex-shaped, bears the expansive force of blank, Structural strength, rigidity, case hardness, surface roughness and machining accuracy are all had higher requirements, the development level of mould production It is one of horizontal important symbol of machine-building, the Double-ejection of mould, can allows and eject flow smoothization, seals some ejections of what The larger product of stroke demand, thimble strength for applying in ejection can be reduced using Double-ejection, avoids causing during ejection The defects of product, but existing Double-ejection is ejected by push rod, but the force deficiency of push rod is easily lead to The problem of not in place is ejected, but existing technology is difficult to overcome above mentioned problem.
Utility model content
The technical problems to be solved in the utility model is that to overcome existing Double-ejection ejected by push rod, still The force deficiency of push rod easilys lead to eject the problem of not in place, there is provided a kind of secondary ejecting mechanism of mould.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme:
The utility model provides a kind of secondary ejecting mechanism of mould, including retainer core, push rod extension bar, push rod, top plate, Two level push rod, lengthening end, back-up ring and spring, the bottom of the retainer core are provided with eight push rod extension bars, and the push rod connects One end of bar is provided with the push rod, and the side of the push rod extension bar is additionally provided with two two level push rods, the two level top One end of bar is provided with the lengthening end, and the both sides of the two level push rod are provided with the back-up ring, and the back-up ring passes through institute State spring connection.
As a kind of optimal technical scheme of the present utility model, the both ends of the back-up ring are respectively provided with camber.
The beneficial effect that the utility model is reached is:The device is a kind of secondary ejecting mechanism of mould, and the device exists It is improved on existing push rod, is provided with push rod and lengthens end, avoids that deflection deformation occurs during ejection, and set on push rod There are back-up ring and spring, Double-ejection can easily be made in place to the elastic force and arc of back-up ring by spring after Double-ejection, entirely Device is reasonable in design, easy to use, and solving existing Double-ejection is ejected by push rod, but the force of push rod is not Foot easilys lead to eject the problem of not in place.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and a part for constitution instruction, with this practicality New embodiment is used to explain the utility model together, does not form to limitation of the present utility model.In the accompanying drawings:
Fig. 1 is overall structure diagram of the present utility model;
Fig. 2 is partial structural diagram of the present utility model;
In figure:1st, retainer core;2nd, push rod extension bar;3rd, push rod;4th, top plate;5th, two level push rod;6th, end is lengthened;7th, back-up ring;8、 Spring.
Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As shown in Figure 1-2, the utility model provides a kind of secondary ejecting mechanism of mould, including retainer core 1, push rod extension bar 2nd, push rod 3, top plate 4, two level push rod 5, lengthening end 6, back-up ring 7 and spring 8, the bottom of retainer core 1 are provided with eight push rod extension bars 2, one end of push rod extension bar 2 is provided with push rod 3, and the side of push rod extension bar 2 is additionally provided with two two level push rods 5, two level push rod 5 One end, which is provided with, lengthens end 6, and the both sides of two level push rod 5 are provided with back-up ring 7, and back-up ring 7 is connected by spring 8.
The both ends of back-up ring 7 are respectively provided with camber, are easy to block by elastic force in ejection.
The device is a kind of secondary ejecting mechanism of mould, and when needing with the device, retainer core 1 can arrange push rod 3 Position directly make 8 push rod extension bars 2, fastened with screw, and centre position, can not directly arrange push rod 3, according to pressure core position Put and directly make two two level push rods 5, two level push rod 5 in ejection, can by the radian of back-up ring 7 slowly compression spring 8, Template is directly skidded off by the power of returning of spring 8 after ejection.
The beneficial effect that the utility model is reached is:The device is a kind of secondary ejecting mechanism of mould, and the device exists It is improved on existing push rod, is provided with push rod and lengthens end, avoids that deflection deformation occurs during ejection, and set on push rod There are back-up ring and spring, Double-ejection can easily be made in place to the elastic force and arc of back-up ring by spring after Double-ejection, entirely Device is reasonable in design, easy to use, and solving existing Double-ejection is ejected by push rod, but the force of push rod is not Foot easilys lead to eject the problem of not in place.
Finally it should be noted that:Preferred embodiment of the present utility model is the foregoing is only, is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic Carry out equivalent substitution.All any modification, equivalent substitution and improvements within the spirit and principles of the utility model, made etc., It should be included within the scope of protection of the utility model.
