Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel die taper pin system, this novel die taper pin system can increase the taper pin operating angle and withdraw from stroke, and it is stressed to reduce friction, thereby prevents that phenomenon of rupture takes place in the taper pin motion process.
To achieve these goals, the technical solution of the utility model is: a kind of novel die taper pin system, but comprise the taper pin that the inclined guide groove with male model benevolence is slidingly matched and the liftout plate of jack-up taper pin, it is characterized in that: the lower end of described taper pin is connected with the upper end of connecting rod, be fixed with briquetting on the described liftout plate to form a chute, described connecting rod passes briquetting and liftout plate, and the middle part of described connecting rod is provided with the latch that is slidingly matched with chute.
Further, the lower end of described connecting rod is provided with the latch that is slidingly matched with the gathering sill that is fixed in the guide holder on the fixed head.
Further, screw connection structure or draw-in groove syndeton are adopted in the upper end of the lower end of described taper pin and connecting rod.
Further, described briquetting through lock pay, draw-in groove or be weldingly fixed on the liftout plate.
Further, described guide holder is paid or is weldingly fixed on the fixed head through lock.
Further, the gathering sill of described guide holder is identical with the angle of inclination of taper pin.
Further, be respectively equipped with on the described taper pin and the corresponding close-fitting through hole of latch.
Compared with prior art, the utlity model has following advantage: (1) this taper pin cooperates mould mother module core and the action of male model benevolence, has solved the overhead kick problem of product in moulding; (2) utilize connecting rod, latch, briquetting and liftout plate etc. simultaneously, can increase the taper pin operating angle and withdraw from stroke, it is stressed to reduce friction, thereby has eliminated the phenomenon of rupture of existing taper pin in the running production process; (3) on fixed head, increase guide holder, play auxiliary component effect, make the stressed of taper pin be significantly improved, reduce the probability of taper pin fracture to a certain extent, prolong the service life of taper pin.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to figure 2 ~ 4, a kind of novel die taper pin system, but comprise the taper pin 1 that the inclined guide groove with male model benevolence is slidingly matched and the liftout plate 4 of jack-up taper pin 1, it is characterized in that: the lower end of described taper pin 1 is connected with the upper end of connecting rod 2, be fixed with briquetting 3 on the described liftout plate 4 to form a chute 41, described connecting rod 2 passes briquetting 3 and liftout plate 4, the middle part of described connecting rod 2 is provided with the latch 7 that is slidingly matched with chute 41, and the lower end of described connecting rod 2 is provided with the latch 7 that is slidingly matched with the gathering sill 51 that is fixed in the guide holder 5 on the fixed head 6.
In the utility model embodiment, screw connection structure, draw-in groove syndeton or other syndetons are adopted in the upper end of the lower end of above-mentioned taper pin 1 and connecting rod 2, screw connection structure can be that the bottom, lower end of taper pin 1 is provided with a screwed hole, and the top, upper end of connecting rod 2 is provided with the external screw thread 21 that matches and be connected with screwed hole; Modes such as above-mentioned briquetting 3 can be paid through lock, draw-in groove or welding are fixed on the liftout plate 4, and it can be to be equipped with screwed hole on briquetting 3, liftout plate 4 that lock is paid a mode, with bolt briquetting 3 is locked on the liftout plate 4; Above-mentioned guide holder 5 is paid or mode such as welding is fixed on the fixed head 6 through lock, and the lock mode of paying can be to be provided with at guide holder 5, to be equipped with screwed hole 52 on the fixed head 6, with bolt guide holder 5 is locked on the fixed head 6; The gathering sill 51 of above-mentioned guide holder 5 is identical with the angle of inclination of taper pin 1; Be respectively equipped with on the above-mentioned taper pin 1 and corresponding latch 7 close-fitting through holes.
