S24: blank molded part is put into shot-blasting machine and removes oxide film dissolving.
Further, it in the step S32, is kept in the electric furnace on hydraulic press in molding die and blank molded part
At a temperature of 800 DEG C~900 DEG C, hydraulic press presses to blank molded part, obtains molded part, and make the thickness H of molded part
For 1.2mm.
Further, the step S4 is specifically included:
S41: molded part is placed in continuous furnace and is heated to 700 DEG C~800 DEG C；
S42: the molded part after heating is placed in the finish forge mould of forging press and carries out accurate school type；
S43: the molded part after the type of accurate school, which is placed in sand-blasting machine, removes oxide film dissolving and spot.
Further, in the step S42, the molded part carries out 1 or 2 accurate school type in finish forge mould.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1. mold uses resistance to height by the way that blank molded part and molding die to be placed in electric furnace while heat in the present invention
The material of temperature, blank molded part can be used hydraulic press to be suppressed in the case where being not to move out electric furnace, blank molded part when compacting
At a temperature of 800 DEG C~900 DEG C, the good fluidity of metal at this time, in the case where hydraulic press is intact, golf iron
The thickness H of head can realize 1.2mm；By disposably forging and pressing the requirement for reaching qualified, eliminates subsequent cumbersome numerical control and add
Work shortens the production cycle.
