Abstract
The invention discloses a retreating mechanism which is applied to a mold. The mold comprises a female mold plate, a male mold plate, an upper ejector plate and a lower ejector plate. The retreating mechanism is characterized by comprising an ejector pin, an ejector plate and an oblique pin, wherein one end of the ejector pin is arranged on the lower ejector plate, and the other end is arranged in the male mold plate in a sliding manner; the ejector plate is arranged in a sliding space of the male mold core of the male mold plate; one end of the oblique pin is fixedly connected with one surface of the ejector plate; and a reverse hook is arranged on one surface of the other end of the oblique pin, and the end is also provided with a patching surface which is in contact with the female mold plate. The retreating mechanism has a simple structure; the oblique pin in the retreating mechanism is relatively short in length and can not be broken due to insufficient strength, and the processing method of the oblique pin is consistent with the common oblique pin processing method; the ejector pin is a standard part, and does not need additional processing, thereby greatly saving the processing cost; and limitation does not exist.
Description
[technical field]
The present invention relates to a kind of drawing-out mechanism, the short drawing-out mechanism that is difficult for taking place fracture of particularly a kind of taper pin length.
[background technology]
All be applied to taper pin in existing most drawing-out mechanism, and generally, when ejecting the product that is provided with breach on some medial surfaces when die sinking, taper pin all will shift out along the breach direction, and need during matched moulds with thimble taper pin is retracted the position, existing drawing-out mechanism is as follows:
Fig. 1 illustrates the structural representation of existing drawing-out mechanism matched moulds state in an embodiment.
Fig. 2 illustrates the structural representation of existing drawing-out mechanism die opening state in an embodiment.
Fig. 3 illustrates thimble and inclined pin structure enlarged diagram in the existing drawing-out mechanism.
Fig. 4 illustrates the enlarged diagram of existing drawing-out mechanism taper pin and product in an embodiment.
With reference to Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, existing drawing-out mechanism, it is applied in the mould, and this mould comprises: caster 10, male model plate 20, upper ejector plate 30 reach liftout plate 40 down, and this drawing-out mechanism comprises:
In present embodiment, during die sinking, male model plate 20 separates with caster 10, and this time liftout plate 40 promotes thimbles 11 motions, cooperates with bayonet socket 121 on the taper pin 12 by the trip on the thimble 11 111 to make taper pin 12 do to eject the motion of disengaging product 50; During matched moulds, thimble 11 is by trip 111 pulling taper pins 12 returns.Because of these taper pin 12 materials are FDAC, its width value has certain qualification, die sinking and matched moulds are frequent when volume production, because of often causing in trip 111 and bayonet socket 121 junctions, the fatigue resistance deficiency ruptures, cause this taper pin 12 to scrap, thereby have a strong impact on volume production, in addition, when this taper pin 12 of processing, need twice line to cut, and thimble also need processing, the corresponding increase of die cost, in addition, there is certain requirement the position of 12 pairs of thimbles 11 of this taper pin, when taper pin 12 angles are excessive, can not use, there is certain limitation, when guaranteeing trip 111 intensity, need guarantee that also thimble 11 do not interfere with taper pin 12 when assembling, so complex structure, the corresponding increase of difficulty during design, and have risk.
[summary of the invention]
In view of this, the object of the present invention is to provide a kind of drawing-out mechanism, this drawing-out mechanism is simple in structure, and the taper pin length in the drawing-out mechanism is shorter, can be because of undercapacity does not rupture, and consistent with common taper pin processing method, and thimble is a standard component, do not need additional processing, saved processing charges greatly, do not have limitation simultaneously.
In order to achieve the above object, drawing-out mechanism of the present invention, it is applied in the mould, and this mould comprises: caster, male model plate, upper ejector plate reach liftout plate down, and this drawing-out mechanism comprises:
Thimble, one end are located on the above-mentioned liftout plate down, and the other end slides and is located in the above-mentioned male model plate;
Top board, it is located in the sliding space of male model benevolence of above-mentioned male model plate;
Taper pin, fixedly connected in a surface of one end and above-mentioned top board, and a surface of the other end of this taper pin is provided with an overhead kick, and this end also is provided with a breaking face, and this breaking face contacts with above-mentioned caster.
Compared to prior art, drawing-out mechanism of the present invention is simple in structure, and the taper pin length in the drawing-out mechanism is shorter, can not rupture because of undercapacity, consistent with common taper pin processing method, and thimble is standard component, do not need additional processing, save processing charges greatly, do not had limitation simultaneously.
For purpose of the present invention, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

[specific embodiment]
With reference to Fig. 5, Figure 6 and Figure 7, drawing-out mechanism of the present invention, it is applied in the mould, and this mould comprises: caster 100, male model plate 200, upper ejector plate 300 reach liftout plate 400 down, and this drawing-out mechanism comprises:
In present embodiment, during die sinking, male model plate 200 separates with caster 100, this time liftout plate 400 promotes thimble 21 motions, thimble 21 penetrates sliding space 202 and then promotes top board 22 and taper pin 23, when the overhead kick 231 of taper pin 23 broke away from the breach 5001 that produces sheet 500 fully, top board 22 just slided to the other end of sliding space 202, thereby product breaks away from taper pin; During matched moulds, caster 100 and male model plate 200 closures, in this process, the breaking face 232 of a surface contact taper pin 23 of caster 100 also promotes taper pin 23 returns.In this drawing-out mechanism during die sinking, thimble 22 promotes taper pin 23 motions by promoting top board 22, during matched moulds, promote taper pin 23 returns by caster 100, need not the cooperation of thimble 21, thus need not the processing that taper pin 23 and thimble 21 is extra, simple in structure, and taper pin length is short, is not easy to take place phenomenon of rupture.
