Description
Technical field
The present invention relates to the technology of die manufacturing field, specifically is a kind of hot stamping die structure.
Background technology
At present, people are in using the hot stamping die production process time, the interpolation of product blank and the product after the punch forming all are manually to load or take out, and this just makes existing hot stamping die structure exist operational sequence more, operates defective cumbersome and that efficient is lower.
Summary of the invention
Technical problem to be solved by this invention is, a kind of easy and simple to handle and hot stamping die structure that can enhance productivity is provided.
For solving the problems of the technologies described above, hot stamping die structure provided by the invention, it comprises patrix, core, core frame and the base plate that is provided with drift; The translateral fixed head of described core frame is installed on the base plate; Described core is provided with the punching press die cavity that matches with drift, and described core frame is provided with first and ejects hole and second and eject the hole; The both sides of described core are installed on the fixed head of both sides movingly through the tooth axle, described core and core frame are movingly so that first eject hole and second and eject the hole and dock, described fixed head is provided with the core that is meshed with the tooth axle and drives tooth bar, and described core drives the tooth bar activity and is engaged in the pilot hole on the fixed head; Be provided with between described core frame and the base plate and be used to the ejecting mechanism that supports blank and finished product is ejected.
After adopting above structure, hot stamping die structure of the present invention compared with prior art has following remarkable advantage and beneficial effect:
By rotating mechanism core is installed on the core frame, eject the hole and dock with the punching press die cavity of core this moment first, ejecting mechanism plays the effect of supporting blank at this moment, after punching press is finished, by ejecting mechanism stamping forming product is rushed to summit earlier, make it loosening, the rotating mechanism drive core of being made up of core driving tooth bar and tooth axle rotates core is toppled over again, and punching press die cavity and second ejects the hole and docks, and can utilize extraneous liftout attachment to go deep into second then and eject the hole finished product is ejected.Whole whole dependence equipment self structure realizes finished product is taken out from mould, need not workman's manual operation, makes to produce comparatively simply, and ejecting mechanism makes that ejecting of finished product is more smooth, is convenient to continuous production, can significantly enhance productivity.
As improvement, it is 90 ° that first on the described core frame ejects the angle that hole and second ejects between the hole, described core and the core frame arcwall face sliding fit through cooperatively interacting.Sliding fit makes that the rotation of core is steadily steady between core and the core frame, and first eject hole and second and eject angle between the hole to be set to 90 ° be setting for the ease of the external device of rushing to summit, after being toppled over, core product can be ejected smoothly, can prevent again because of the inclination angle excessive, product comes off automatically, is not easy to reclaim.
As further improvement, be provided with the space that ejecting mechanism is installed through back-up block between described core frame and the base plate, described ejecting mechanism comprises first elastic component, push rod and backing plate; Described fixed head is provided with backing plate stroke mouth; Be provided with guide pillar between described backing plate and the base plate; Described first elastic component is between core frame and backing plate; One end of described push rod is connected with backing plate, and the other end is positioned at first and ejects the hole; The both sides of described backing plate are provided with pull bar, and described pull bar is through torsion spring and fixed head is hinged and it is terminally ganged up with in backing plate stroke mouth position and backing plate; Also be provided with release unit between described backing plate and the pull bar.By press machine pulling pull bar, pull bar then spurs backing plate, driving push rod by backing plate rushes to summit to product its loosening and back-moving spring is compressed, when push rod product is ejected first eject the hole after, release unit separates pull bar with backing plate, backing plate falls automatically in the deadweight and the elastic force effect lower edge guide pillar of back-moving spring, and rotating mechanism just can drive core and topples over like this.This ejecting mechanism also is design feature and the operation principle that has made full use of rotating mechanism and mould self, constitutes organic whole, interdependence with said structure.
As improvement, described rotating mechanism is meant, the core driving tooth bar that the both sides of described core are equipped with the tooth axle and are meshed with the tooth axle, the locating hole that described fixed head is provided with pilot hole and is communicated with pilot hole, described core drives the tooth bar sliding fit on fixed head in the pilot hole, one end of described tooth axle is fixedlyed connected with core, and the other end is free to rotate is engaged in the locating hole on the fixed head.The engaged transmission that drives between tooth bar and the tooth axle by core makes that the rotation of core is comparatively stable, this structure all is set in the core both sides can further strengthens the stability that core rotates again, and, the mounting structure of core driving tooth bar and tooth axle has made full use of the structure of mould self, make whole rotational structure comparatively compact, be beneficial to the reliability that improves rotating mechanism.
As improvement, also be provided with positioner between described patrix drift and the core.Positioner is set to be helped core and keeps stable in the course of the work.
Concrete, described positioner comprises lead and pilot hole, and described lead is fixedlyed connected with the patrix drift, and described pilot hole is positioned on the core.This structure is a conventional design in the mould design, and reliable in structure, practicality can be saved design cost and manufacturing cost like this.
As preferably, described drift is an outer-hexagonal bolt drift.Like this, the present invention just is suitable for making the outer-hexagonal bolt.
