As a further improvement on the present invention, the thimble in the male model just with male model material package location face.
As a further improvement on the present invention, the inner ring top with thickening inner ring molding space face is additionally provided in the male model
Pin.
As a further improvement on the present invention, the quantity of the inner ring thimble is four, and is thickening inner ring molding space
Position is uniformly distributed.
As a further improvement on the present invention, the cast gate of the mold is located at mold center.
A kind of molding die insert processing method of light small magnesium alloy heat radiation fan described in claim 1 is specific to walk
It is rapid as follows：
Step 1：It is first cut using line and each insert is cut into flat construction insert one by one；
Step 2：An auxiliary template is processed, is formed on each auxiliary template and is embedded flat construction insert for fixation
Locating slot；
Step 3：The insert of each flat construction is fixedly installed in locating slot, the insert of each flat construction is matched somebody with somebody
It is flat；
Step 4：The flat construction insert on auxiliary template is processed and formed at one time by the way of electro-discharge machining, is formed
The arcuate structure consistent with electric fan shape；
Step 5：The insert machined is removed to the machine-shaping for completing insert from auxiliary template.
The beneficial effects of the invention are as follows：The present invention is thickeied by designing thickening inner ring molding space in male die core to be molded
Fan inner ring, and realize by way of mold insert the shaping of each weak flabellum, be conducive to the shaping and the demoulding of product, die casting
The intact material of product and metaboly out particularly by the design of special male model material bag and exhaust passage, are further realized
Product smoothly shaping and the demoulding, is conducive to improve fan formed precision and product strength, be set due to being thickeied in fan at inner ring
Inner ring thimble is counted, thimble is designed at male model material bag, can smoothly realize that product stripping simultaneously, does not influence Product Precision and appearance.
