Abstract
The utility model discloses a thimble device including a plurality of thimbles, wherein, the first thimble is fixed on the lower thimble plate by socket. An upper thimble plate is provided on the lower thimble plate. A cavity is provided between the upper thimble plate and the lower mold plate. Thimble holes are respectively provided on the upper thimble plate and on the lower mold plate. The first thimble goes through the thimble holes of the upper thimble plate into the cavity, and then penetrated into the thimble holes of the lower mold plate. A fixing plate is arranged under the lower thimble plate and the second thimble is fixed on the fixing plate. The second thimble is formed in the way of that the first thimble on the socket stretches out an appending end of opposite direction with the opposed face of the first thimble. Corresponding second thimble holes are provided on the upper thimble plate, on the lower thimble plate, and on the lower mold plate. The second thimble goes through the upper thimble plate and the lower thimble plate into the cavity and then penetrated into the lower mold plate. When liftout, the first thimble makes the first liftout, then the fixing plate drives the appending end of the second thimble to make the second liftout. The thimble device can avoid the damage of the finished product when lifting out of the latent gate.

Bei Jing Ji Intraoperative
As shown in Figure 1, a kind of known top needle device, this device comprises some thimbles, its thimble 12 is fixed in down on the ejector retainner plate 13 by base 11, and ejector retainner plate 14 on is arranged on the following ejector retainner plate 13, and 15 of last ejector retainner plate 14 and lower bolsters have a cavity 19, be an activity space distance, last ejector retainner plate 14 and lower bolster 15 are provided with centre hole 16, and thimble end 12 passes ejector retainner plate 14 and enters cavity 19, penetrate the centre hole 16 of lower bolster 15 again; When ejecting, following ejector retainner plate 13 motions eject action and once finish.
The shortcoming of above-mentioned known technology is: in the mould with sub marine gate 27, known top needle device pushing method is pulled finished product 28 easily when cast gate is pulled away from finished product 28.
Summary of the invention
For addressing the above problem, the utility model proposes a kind of push pin device, this device comprises some thimbles, and first thimble is wherein arranged, and is fixed in down on the ejector retainner plate by base, on the following ejector retainner plate ejector retainner plate on is arranged, one cavity is arranged between last ejector retainner plate and lower bolster, be an activity space distance, last ejector retainner plate and lower bolster respectively are provided with centre hole, the centre hole that first thimble passes ejector retainner plate enters cavity, penetrates the lower bolster centre hole again; Other has a fixed head to be arranged on down under the ejector retainner plate, and second thimble is fixed thereon, this second thimble, be by above-mentioned first thimble on base, extend an additional terminals in opposite directions with the first thimble opposite face, and form; Wherein, the second thimble base replaces base, and it forms a projection at second thimble and additional terminals, and last ejector retainner plate, time ejector retainner plate and lower bolster are provided with the corresponding second thimble centre hole, second thimble passes ejector retainner plate, ejector retainner plate enters cavity down, penetrates lower bolster again.
The above-mentioned second thimble centre hole, at last ejector retainner plate, following ejector retainner plate, the projection of the relative second thimble base, ad hoc have one section cavity distance, and the motion of the protruding second thimble base is limited in this section cavity distance.
Said apparatus designs through these, when ejecting, first thimble does to eject for the first time action earlier, fixed head drives the second thimble additional terminals, second thimble just begins to do to eject for the second time action, such secondary liftout attachment can avoid sub marine gate when ejecting, and when cast gate is pulled away from finished product finished product is pulled; In addition, second thimble is designed to the bipartial thimble, is to increase the intensity of thimble, and deflection deformation takes place when avoiding ejecting.

The specific embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
As shown in Figure 2, a kind of push pin device, this device comprises some thimbles, and first thimble 22 is wherein arranged, and is fixed in down on the ejector retainner plate 23 by base 21, ejector retainner plate 24 on one is arranged on the following ejector retainner plate 23,25 of last ejector retainner plate 24 and lower bolsters have a cavity, are an activity space distance, and last ejector retainner plate 24 and lower bolster 25 respectively are provided with centre hole 26, the centre hole 26 that first thimble 22 passes ejector retainner plate 24 enters cavity, penetrates lower bolster 25 centre holes 26 again; Other has a fixed head 37 to be arranged on down under the ejector retainner plate 23, and second thimble 32 is fixed thereon, this second thimble 32, be by above-mentioned first thimble 22 on base 21, extend an additional terminals 38 in opposite directions with first thimble, 22 opposite faces, and form; Wherein, the second thimble base 31 replaces base 21, and it forms a projection in second thimble 32 and additional terminals 38, last ejector retainner plate 24, following ejector retainner plate 23 and lower bolster 25 are provided with the corresponding second thimble centre hole 36, second thimble 32 passes ejector retainner plate 24, ejector retainner plate 23 enters cavity down, penetrates lower bolster 25 again.
The above-mentioned second thimble centre hole 36, at last ejector retainner plate 24, following ejector retainner plate 23, the projection of the relative second thimble base 31, ad hoc have one section cavity distance, and the motion of the protruding second thimble base 31 is limited in this section cavity distance.
In the present embodiment, when push pin device ejected, the cavity of 25 of ejector retainner plate 24 and lower bolsters in the utilization, following ejector retainner plate 23 were done near lower bolster 25 motions, and first thimble 22 disposed thereon is done earlier for the first time to eject action, and it ejects (as shown in Figure 3) with product 28; Second thimble 32, because centre hole is at last ejector retainner plate 24, following ejector retainner plate 23, the projection of the relative second thimble base 31, ad hoc have one section cavity distance, make second thimble 32 not be subjected to down ejector retainner plate 23 motion effects, thereby do not do and eject motion, make that ejector retainner plate 23 is isolated a space length with fixed head 37 down; Fixed head 37 drives second thimble, 32 additional terminals 38, does near ejector retainner plate 23 motions down, and second thimble 32 just begins to do to eject action for the second time, and it ejects sub marine gate 27; Such secondary liftout attachment can avoid sub marine gate 27 when ejecting, and when cast gate is pulled away from finished product 28 finished product 28 is pulled (as shown in Figure 4).
In mould with sub marine gate 27, if certainly will pull finished product 28 according to the known top needle device, and the utility model can be done successively to eject for twice, as required, first thimble 22 is arranged on the sub marine gate 27, and second thimble 32 is arranged on the finished product 28, then, sub marine gate 27 is ejected for the first time, and finished product 28 is waited a moment and ejected for the second time; Otherwise, with first thimble 22, second thimble, 32 reversing of position, the also corresponding transposing of priority that sub marine gate 27 and finished product 28 eject.
