Abstract
The utility model relates to an angle pin structure of a die, which is used in a die with a male die part. The angle pin structure includes an angle pin, an ejection rod and a pretensioning spring, and is characterized in that the angle pin is matched with a reverse buckle of a product formed by a female die core and a male die core of the die; an inclined guide slot is correspondingly arranged in the male die core; the angle pin can slide on the male die core in an inclined direction by virtue of the inclined guide slot; an ejection rod is arranged at the bottom end of the angle pin; the ejection rod is composed of two sections, which are connected together through the pretensioning spring; a clamp groove is arranged in one section of the ejection rod, and is in matched connection with a groove arranged in the angle pin; and the other section of the ejection rod is mounted between an upper ejection board and a lower ejection board. The novel angle pin structure of the die, disclosed by the utility model, can solve the problems about insufficient strength of the angle pin and over-pulling damaged caused during withdrawing of the angle pin.
Description
Technical field
The utility model relates to a kind of mould structure, particularly a kind of mould inclined pin structure.
Background technology
When the product of mould institute moulding has overhead kick, need use angle pin ejection mechanism, be illustrated in figure 1 as taper pin mechanism in the existing mold, this mould male model partly comprises: taper pin 1, it is located in the male model benevolence, and taper pin 1 is provided with draw-in groove 10; One taper pin seat 2 is placed on the liftout plate, which is provided with groove 20.Taper pin 1 connects with groove 20 by draw-in groove 10 with taper pin seat 2.
Because taper pin length is longer, in the taper pin course of action, can produces bigger moment of flexure and make the taper pin clamping stagnation and then broken; Simultaneously, because the trueness error that the taper pin size is made, retract in the process at taper pin and can cause the problem of drawing, cause taper pin to break damage.
Summary of the invention
The purpose of this utility model is to provide a kind of and shortens taper pin length, increases taper pin intensity and prevent that taper pin from producing the mould inclined pin structure of the bad problem of pulling open.
To achieve the above object, the utility model has adopted following technical scheme: a kind of novel die inclined pin structure, this structure is used for comprising the mould of male model part, and it comprises taper pin, push rod, prestretching spring, and this taper pin cooperates the overhead kick of this mould mother module core and male model benevolence shaped article; On this male model benevolence inclined guide groove is set accordingly, taper pin can be done oblique slip along male model benevolence by inclined guide groove, and the bottom of described taper pin is provided with push rod, push rod is divided into two-part, connected by prestretching spring prestretching, wherein one section push rod is provided with draw-in groove, connects with the groove fit that arranges on the taper pin; Another section push rod is installed in up and down between the liftout plate.
Than prior art, the novel die taper pin mechanism of the utility model, the mistake that produces in the time of can solving taper pin undercapacity and taper pin and retract is drawn the damage problem.
Description of drawings
Fig. 1 is inclined pin structure schematic diagram in the existing mold.
Fig. 2 is the utility model inclined pin structure schematic diagram.
Fig. 3 is the structural representation of the utility model push rod taper pin combination.
Fig. 4 is the structural representation of the utility model push rod.
Fig. 5 is the structural representation of the utility model taper pin slide block.
Among the figure: liftout plate 10-groove 20-draw-in groove 21-upper ejector pin 22-lower push rod 23-spring card slot under the 1-taper pin 2-push rod 3-prestretching spring 4-upper ejector plate 5-.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Comprise a taper pin 1, push rod 2, prestretching spring 3 and the upper and lower liftout plate that matches with it and male model benevolence referring to Fig. 2 the utility model.Referring to Fig. 3, Fig. 4, Fig. 5, the inclined guide groove in taper pin 1 and the male model benevolence cooperates slip, and while taper pin 1 is provided with groove 10; Push rod 2 is made of last knock-pin 21 and following knock-pin 22, and the draw-in groove 20 that while upper ejector pin 21 is provided with cooperates with the groove 10 on the taper pin 1, is equipped with spring card slot 23 on upper ejector pin 21 and the lower push rod 22; Prestretching spring 3 links up upper ejector pin 21 and lower push rod 22 by spring card slot 23.Upper ejector plate 4 and following liftout plate 5 are realized motion simultaneously by screw attachment.
So, when this mould die sinking, upper ejector plate 4 and following liftout plate 5 rise together, and then drive push rod 2 rises, because the draw-in groove 20 on the push rod 2 connects with the groove 10 on the taper pin 1, thereby promote taper pin 1 rising, again because taper pin 1 cooperates slip with the inclined guide groove of male model benevolence, thereby being moved along oblique upper, taper pin 1 breaks away from the product overhead kick.When the mould matched moulds, upper ejector plate 4 and following liftout plate 5 retract together, drive push rod 2 and retract, and then drive taper pin 1 retracts in the die along oblique below by inclined guide groove.When taper pin contacts die in advance, when upper ejector plate 4 and following liftout plate 5 still continue to move down, offset the amount of drawing by the elongation of prestretching spring 3, can avoid taper pin 1 and push rod 2 to draw the damage that causes owing to crossing like this.
The utility model does not limit to above-mentioned preferred embodiments, and anyone can draw other various forms of mould taper pin assemblies under enlightenment of the present utility model.All equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
