Description
Technical field
This utility model belongs to securing member field shaping technique, specifically just relates to a kind of welded nut cold-heading molding mold insert structure。
Background technology
Machinery industry generally use various hardwares as processing and install, such as securing member is exactly a kind of common hardware, securing member securing member commercially also referred to as standard component be two or more parts or component are fastenedly connected become one overall time the general name of class machine components that adopts。Its feature is that description various performance purposes is different and standardization, seriation, unitized strong。Securing member is that most widely used mechanical basic part is in great demand。Nut is a kind of common securing member, the common nut of tradition is square or hexagon, and it does not have particular/special requirement when being used for assembling for installation tool, and therefore range of application is very extensive, but these common nuts are used for generation stripped thread phenomenon of skidding, cause that connecting shakiness is susceptible to security incident。
The defect of stripped thread it is susceptible in order to solve above-mentioned existing nut processed complex, occur in that welded nut in the market, welded nut is not only able to be threaded connection, by the mode welded, part can also be securely fixed, welded nut utilizes cold heading technique to complete, need to make special cold upsetting die of car to make, it is to avoid traditional mechanical processing technique makes wastes raw-material defect。
Utility model content
This utility model purpose is aiming at existing welded nut manufacturing process and wastes raw-material technological deficiency, a kind of welded nut cold-heading molding mold insert structure is provided, utilize the making of this core rod memory weld mold, it is possible to reduce welded nut and make raw-material loss, decrease product cost。
Technical scheme
In order to realize above-mentioned technical purpose, a kind of welded nut cold-heading molding mold insert structure of this utility model design, it is characterized in that: it includes mold core body, described mold core body includes fixed part and forming part, described forming part is provided with nut forming tank, equipped with nut internal formed block bottom described nut forming tank, nut inner hole molding mold insert is contained in the forming tank of nut internal formed block, it is contained on block rubber bottom described nut internal formed block, it is provided with forming ejector pin bottom nut internal formed block, forming ejector pin props up nut inner hole molding mold insert through the via of block rubber and nut internal formed block。
Further, described mold core body periphery is provided with spacing preiection。
Further, described nut inner hole molding mold insert is hexagonal cylinder。
Beneficial effect
A kind of welded nut cold-heading molding mold insert structure that this utility model provides, utilizes this core rod for the making of weld mold, it is possible to reduces welded nut and makes raw-material loss, decreases product cost。
