Abstract
The invention discloses a mold threaded machining method. A first mold core and a second mold core are placed on a work table of an electric discharge machine, a gap exits between the first mold core and the second mold core, the centers of threaded bottom holes of the first mold core and the second mold core are corrected to be located on the same plane with the moving track of a spindle of the electric discharge machine; the spindle drives an electrode to transversely move to complete threaded hole machining of the first mold core and the second mold core, and therefore continuity of screw hole threads is ensured, and the quality of forming parts is ensured.
Description
Technical field
The present invention relates to field of machining is and in particular to a kind of mould Screw thread process method.
Background technology
The part of many casting formings needs threading at present, due to external screw thread shape presence cannot release problems,
The externally threaded center that is therefore typically at present is die joint, therefore the screwed hole of mould is divided into two, then by electric discharge machine
Processing processing screw hole, and traditional processing is using the screw that electrode separate machined is half of, therefore, after two mould matched moulds, meeting
Screwed hole linking is caused to have some setbacks, major diameter of thread equidimension is difficult to be controlled, it is bad to thus result in the product quality processing, in view of with
Upper defect, is necessary to design a kind of mould Screw thread process method in fact.
Content of the invention
The technical problem to be solved is:A kind of mould Screw thread process method is provided, to solve existing mould
It is connected, after tool screw processing, the problem having some setbacks.
For solving above-mentioned technical problem, the technical scheme is that:A kind of mould Screw thread process method, with screwed hole
Mould is divided into the first core rod and the second core rod for die parting line by heart line;It is characterized in that, comprise the following steps:
First core rod described in electro-discharge machining and described second core rod screw thread;Described first core rod and described second core rod are put
Put on electric discharge machine workbench, and there is gap between described first core rod and described second core rod;Correct described first
The described thread Pilot hole center of core rod and described second core rod is with electric discharge machine main axle moving track at grade;By master
Axle drives described electrode translation to complete described first core rod and described second core rod hole processing.
Further, before electro-discharge machining, the following steps carrying out in order are also included:
Step one):The thread Pilot hole of the first core rod described in roughing and described second core rod made allowance;
Step 2):By step one) described first core rod of gained and described second core rod heat treatment;
Step 3):By step 2) described first core rod of gained and described second core rod finishing, all spiral shells
Line bottom outlet dimensioned puts in place.
Further, step one) in, described thread Pilot hole made allowance is 0.15+00.15.
Further, before electro-discharge machining, also include described first core rod and described second core rod processing electricity
The step of pole;With red metal or red copper bar as base material, turnery processing external screw thread.
Further, the distance between described first core rod and described second core rod are more than described electrode diameter.
Further, described electric discharge machine is numerical control electric spark machine.
Compared with prior art, this mould Screw thread process method, described first core rod and described second core rod are placed on
On electric discharge machine workbench, and there is gap between described first core rod and described second core rod;Correct described first core rod
With the described thread Pilot hole center of described second core rod with electric discharge machine main axle moving track at grade;By main shaft band
Dynamic described electrode translation completes described first core rod and described second core rod hole processing, thereby ensure that the company of screw screw thread
Continuous property is it is ensured that the quality of formation of parts.
