Abstract
The utility model provides an angle pin fixing mechanism applied to a die. The die comprises a glue inlet, a female die cavity, and a male die cavity provided with a glue inlet flow passage. The angle pin fixing mechanism comprises an angle pin, a slide block, and a dowel. One end of the angle pin is placed inside the male die cavity, the angle pin is provided with a groove, and one side of the angle pin contacts the glue inlet flow passage in a corresponding mode. One end of the slide block contacts the female die cavity, the other end of the slide block contacts the male die cavity, and a sliding groove is arranged inside the male die cavity. The dowel is arranged inside the sliding groove, one end of the dowel is arranged inside the groove in a corresponding mode, and the other end of the dowel contacts the slide block. The groove is arranged in one side of the dowel, the dowel is arranged inside the male die cavity, one end of the dowel is arranged inside the groove in a corresponding mode, and the other end of the dowel contacts the slide block. When products are formed in an injection mode, the slide block presses the dowel tightly, the dowel locks the angle pin tightly, and therefore no matter how large injection pressure of plastic and forming pressure of the products are, the angle pin can keep fixed constantly.
Description
[technical field]
The utility model relates to a kind of taper pin fixed mechanism, particularly relates to a kind of taper pin fixed mechanism be applied in mould.
[background technology]
When producing plastic cement products, overhead kick is set sometimes on product, can not leave the situation of die and occur in order to prevent when die sinking overhead kick, usually a taper pin can be set in mould, yet, when taper pin one end participates in the moulding of product, taper pin can be mobile under the effect of briquetting pressure, cause product the thick abnormal phenomenon of meat to occur, reduce the yield of product; In addition, when taper pin one side, when entering the solation road and contact, the ejaculation pressure due to the glue-feeder plastic cement when injection moulding is large, and taper pin penetrates at plastic cement can be mobile under the effect of pressure, causes product the phenomenon of burr to occur.
Refer to Fig. 1, its generalized section that is prior art, when injection moulding, because of glue-feeder 10 with enter solation road 11 and be connected, and glue-feeder 10 with enter solation road 11 and be placed in male die core 12, again taper pin 13 with enter solation road 11 and contact, when the plastic cement of melting flow into by glue-feeder 10 in solation road 11 time, because the ejaculation pressure of plastic cement is large and taper pin 13 is not fixed, the effect that taper pin 13 is subject to penetrating pressure can be moved, in addition, when the plastic cement of melting enters into die cavity, because taper pin 13 1 ends have participated in the moulding of product 14, taper pin 13 also there will be mobile phenomenon under the effect of briquetting pressure.
In view of this, be necessary to provide a kind of taper pin fixed mechanism in fact, this taper pin fixed mechanism can solve the problem that taper pin moves when injection molding product existed in above-mentioned technology.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of taper pin fixed mechanism, and this taper pin fixed mechanism can solve while being set forth in injection molding product the problem that taper pin moves.
In order to achieve the above object, taper pin fixed mechanism of the present utility model, it is applied in mould, and this mould comprises that a glue-feeder, a mother module core and are provided with into the male die core in solation road, and this taper pin fixed mechanism comprises:
One taper pin, the one end is placed in described male die core, and this taper pin is provided with a groove, and this taper pin one side advances with described that the solation road is corresponding to contact;
One slide block, this slide block one end contacts with described mother module core, and the other end contacts with described male die core, is provided with a sliding tray in this male die core; And
One pin, it is located in described sliding tray, and this pin one end correspondence is placed in described groove, and the other end contacts with described slide block.
Preferably, to be placed in this end of groove be bullet to described pin correspondence.
Preferably, contacted this end of described pin and slide block is T-shaped.
Preferably, the direction that described pin slides is perpendicular to advancing the glue direction.
Preferably, the material of described pin is metal.
Preferably, the material of described pin is steel.
Compared to prior art, taper pin fixed mechanism of the present utility model, by in taper pin one side, groove being set, and pin is set in male die core, and this pin one end correspondence is placed in groove, and the other end contacts with slide block, when injection molding product because slide block compresses pin, pin locking taper pin, therefore no matter the briquetting pressure of the ejaculation pressure of plastic cement and product is much, it is fixing that taper pin keeps always.
[accompanying drawing explanation]
Fig. 1 illustrates the generalized section of prior art.
Fig. 2 illustrates the generalized section of the utility model taper pin fixed mechanism when the mould matched moulds.
Fig. 3 illustrates the generalized section of the utility model taper pin fixed mechanism when the mould die sinking.
[specific embodiment]
Refer to shown in Fig. 2 and Fig. 3, wherein Fig. 2 is the generalized sections of the utility model taper pin 104 fixed mechanisms when the mould matched moulds, and Fig. 3 is the generalized sections of the utility model taper pin 104 fixed mechanisms when the mould die sinking.
One taper pin 104, the one end is placed in described male die core 103, this taper pin 104 is provided with a groove 106, and these taper pin 104 1 sides with advance that solation road 102 is corresponding to contact, in the present embodiment, this groove 106 is placed between glue-feeder 100 and mother module core 101;
One slide block 107, these slide block 107 1 ends contact with described mother module core 101, and the other end contacts with described male die core 103, is provided with a sliding tray 105 in this male die core 103, and in the present embodiment, this sliding tray 105 is T-shaped; And
One pin 108, it is located in above-mentioned sliding tray 105, these pin 108 1 end correspondences are placed in described groove 106, the other end contacts with described slide block 107, in the present embodiment, refer to Fig. 2, this end that pin 108 correspondences are placed in groove 106 is bullet, described pin 108 is T-shaped with contacted this end of slide block 107, and the direction that pin 108 slides is perpendicular to advancing the glue direction.
Wherein, the material of described pin 108 is metal, and in the present embodiment, the material of described pin 108 is steel.
In the present embodiment, refer to Fig. 2, when the mould matched moulds, slide block 107 is toward the direction motion of entering solation road 102, in motion process, slide block 107 contacts with pin 108, pin 108 is done motion in the same way with slide block 107 under the drive of slide block 107, when pin 108 correspondences are placed in groove 106, pin 108 stop motions, slide block 107 is due to the drag effect that is subject to pin 108 also stop motion, pin 108 is compressed by slide block 107, pin 108 locking taper pins 104, when the plastic cement of melting flow into by glue-feeder 100 in solation road 102 time, no matter the ejaculation pressure of plastic cement is much, taper pin 104 can not be moved.
