Description
Technical field
The utility model relates to a kind of screw mfg. moulding die, relates in particular to a kind of screw mold.
Background technology
As a kind of standard component that is fixedly connected with, screw is seen everywhere in modern production and life.Just punching is as one of cold forging die necessary in the screw production industry, and it is mainly used in the predeformation of material, and the control accuracy of its size will satisfy the requirement in the screw production process.Existing mould just rushes the repair rate height, and production efficiency is low, and service life is short, and product quality can't strict guarantee.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of production efficiency high, the screw mold of long service life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of screw mold, comprise die ontology, and be provided with manhole in the middle of this mould, a described mould wherein end is provided with die cavity, and this die cavity is communicated with described manhole.
In order to improve the machining accuracy of product, further, described die cavity is made of the die cavity circular hole that is arranged on die tip and the die cavity taper hole that is arranged on die cavity circular hole rear portion.
Further, described die cavity length h is 3.25-3.35mm.
Further, described die cavity circular hole diameter D is 7.0-7.1mm.
Further, the tapering C of described die cavity taper hole is 10 °, and the taper hole diameter d is 4.4mm.
Compared with prior art, usefulness of the present utility model is: this screw mold is convenient to control the machining accuracy of product, Effective Raise production efficiency, the significant prolongation in service life of product, qualification rate and output efficiency improve, and reduce production costs, and guarantee well product quality.
