Step 2, natural cooling and natrual ageing, place to workpiece and cool down at room temperature；
Step 3, for the workpiece that frame is deep, if the size of thickness is less than the 1/3 of height, consider tempering heat treatment；
Step 4, in order to follow-up easy to process, stay iron appropriate between the first width and the second width, turn into technique pin
D；
Step 5, heat in a vacuum furnace, to 480 degrees Celsius, and be incubated 2-4 hours；
Step 6, continue to be heated up to 560-580 degrees Celsius, afterwards and be incubated 8-10 hours；
Step 7, it is cooled to room temperature；
Step 8, surrounding are polished with grinding machine；
Step 9, remove technique pin；
Step 10, measurement；
Step 11, tolerance is machined to according to the surplus of measurement；
Step 12, twenty four hours is placed at room temperature；
Step 13, then measure, verify whether to deform.
Compared with prior art, the present invention has following beneficial effect：The structure of the present invention is symmetrical, can solve tool
There is the problem of machining accuracy of the micron order mould of a workpiece for word structure, eliminate the inside casing of door word structure in process
The problem of workpiece deforms caused by because of stress release.
