Forming die of light weight and small size magnesium alloy cooling fan and processing method of inserts therefor

Abstract

The invention discloses a forming die of light weight and small size magnesium alloy cooling fan and a processing method of inserts therefor. A male die of a die is internally provided with a core insert, a female die is internally provided with a cavity insert, and a die-casting cavity is formed between the male die and the female die; a circular thickened inner race forming space is formed in the male die, a plurality of insert grooves corresponding to the positions of fan blades of the fan are uniformly distributed outside the circumference of the thickened inner race forming space, the inserts are respectively embedded in all insert grooves, and blade forming structures are respectively formed at the two sides of each insert; an insert processing method comprises the following steps: cutting all the inserts into inserts of straight structures; processing an auxiliary template; installing the inserts of the straight structures on the auxiliary template to trim the inserts; discharging the processed inserts to be of arc-shaped structures which are consistent with the shapes of the fan blades; taking out the inserts after the completion of the processing. The forming die provided by the invention is beneficial for product forming and de-moulding, is high in fan forming precision and product intensity.

Description

technical field [0001] The invention relates to a die-casting mold, in particular to a forming mold for a light and small magnesium alloy cooling fan and a processing method for the insert used therein. Background technique [0002] In order to meet the requirements of the ever-decreasing size of electronic products, the cooling fan used in electronic products also needs to be reduced in size and the thickness of the fan blades. Due to the small size of the fan and the thinness of the fan blades, the fan blades of the fan are very fragile. Conventional Die-casting molds cannot achieve magnesium alloy die-casting, and often the products after die-casting have material shortages, deformation, and cannot be demolded. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a molding die for a light and small magnesium alloy cooling fan. The molding die for the light and small magnesium alloy cooling fan has a simple s...
