Abstract
The utility model discloses a connecting mechanism of a beveled pin and a pull rod, and a die provided with the connecting mechanism, pertaining to the technical field of dies. The connecting mechanism comprises a groove which is cut on one end face of the beveled pin. A convex section is arranged at the rabbet of the groove while the extending direction of the convex section is intersected with the direction of the groove depth of the groove. The connecting mechanism also comprises a clamping part which is arranged on the pull rod and can be inserted into the groove along the direction of the groove depth of the groove. The clamping part is provided with a limiting part which is used for limiting the clamping part into the groove, the extending direction of the limiting part is intersected with the direction of the groove depth of the groove. When in use, the clamping part of the pull rod is inserted into the groove of the beveled pin and at this time the limiting part and the convex section are positioned in a location that are not in contact with each other; and then the pull rod is rotated to cause the limiting part and the convex part to press against with each other and the clamping part is fixedly clamped in the groove, thus the connection of the pull rod and the beveled pin is completed.
Description
Technical field
The mould that the utility model relates to a kind of taper pin pull bar syndeton and has this syndeton belongs to technical field of mold.
Background technology
Taper pin is a kind of common structure in the mould, and pull bar is used to connect taper pin, and the traditional connected mode between pull bar and the taper pin is to adopt grab that the two is tightened.The employing grab connects, the processing technology of grab is comparatively complicated, and need correspondingly flexible connection latch closure to be set to be used for fixing grab, so not only cause the reduction of production efficiency, the raising of production cost, and the compactness inadequately that seems of the syndeton between taper pin and the pull bar.
Summary of the invention
The technical problems to be solved in the utility model provides the syndeton between a kind of compact conformation, the taper pin that is easy to process and the pull bar.
Another technical problem to be solved in the utility model provides a kind of mould with the syndeton between compact conformation, the taper pin that is easy to process and the pull bar.
The technical scheme that the utility model adopted is: a kind of taper pin pull bar syndeton, it comprises the groove on the end face that is opened in taper pin, also be provided with the crossing protuberance of groove depth direction of bearing of trend and groove at the notch position of described groove, this syndeton also comprises being arranged on can insert holding section in the described groove along the groove depth direction of described groove on the pull bar, and the groove depth direction that has bearing of trend and described groove on the described holding section intersects and can be with the spacing limiting section in described groove in described holding section.
Further spacing, the groove depth direction of the bearing of trend of described protuberance and described groove is perpendicular.The groove depth direction of the bearing of trend of described limiting section and described groove is perpendicular.
The technical scheme that the utility model adopted is: a kind of mould, it comprises aforesaid taper pin pull bar syndeton.
Because the employing of technique scheme in use, is at first inserted the holding section of pull bar in the groove of taper pin, this moment, limiting section and protuberance were in not contacted position; Rotating tension bar then makes limiting section lean with protuberance and being connected of pull bar and taper pin can be finished by firm being held in the holding section in the groove.
This kind taper pin pull bar syndeton and used the mould of this kind syndeton to have the characteristics of compact conformation, handling ease, saving processing cost.

The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:
Referring to Fig. 1, a kind of taper pin pull bar syndeton, it comprises the groove 11 on the end face that is opened in taper pin 1, also be provided with the perpendicular protuberance 12 of groove depth direction of bearing of trend and groove 11 at the notch position of described groove 11, referring to Fig. 4, the setting of described protuberance 12 promptly makes the diameter of notch of described groove 11 less than the diameter of the vallecular cavity of described groove 11, and described protuberance 12 produces an overhead structure at the notch place of groove 11.This syndeton also comprises being arranged on can insert holding section 21 in the described groove 11 along the groove depth direction of described groove 11 on the pull bar 2, and it is perpendicular and can be with described holding section 21 spacing limiting sections 22 in described groove 11 to have the groove depth direction of bearing of trend and described groove 11 on the described holding section 21.
In Fig. 1, described limiting section 22 leans with described protuberance 12 and with holding section 21 firm being held in the groove 11.Referring to Fig. 4, when pull bar 2 after taper pin rotates 90 ° of angles, described limiting section and described protuberance 12 are separated, holding section 21 can be deviate from groove 11 thus.
Referring to a kind of mould among Fig. 5, it comprises moving platen 3, pillow plate 4, and upper ejector plate 5, following liftout plate 6, it also comprises taper pin 1, pull bar 2, adopts aforesaid taper pin pull bar syndeton between described taper pin 1, the pull bar 2.
