A die-casting mold for a magnesium alloy fan

Abstract

The invention provides a die-casting die for a magnesium alloy fan. According to the die-casting die, sliding blocks serve as a component of a cavity, the sliding blocks can be quickly disengaged from a product in the releasing process, it is ensured that the product can be smoothly taken out, the service life of the die is prolonged, and mass production is achieved. The die-casting die comprises a female die part and a male die part. The female die part comprises a female die plate, a female die core, a sprue sleeve structure, inclined guide columns and a shovel base. The male die part comprises a male die plate, a male die core, a center, an upper center plate, a lower center plate, a bottom plate and a central insert. The space composed of the female die plate and the male die plate is internally provided with the female die core, the male die core and the central insert, the sprue sleeve structure is arranged on the upper portion of the central insert, and an upper end runner is arranged in the sprue sleeve structure. The die-casting die is characterized in that sliding block assemblies arranged in pairs are arranged on the two sides of the part, between the female die core and the male die core, of the cavity respectively, and the sliding block assemblies comprise the sliding blocks located on the inner sides and sliding block seats located on the outer sides.

Description

technical field [0001] The invention relates to the technical field of mold structures, in particular to a die-casting mold for a magnesium alloy fan. Background technique [0002] At present, in the die-casting mold design and manufacturing process of magnesium alloy fans, our design and manufacturing technology is still in the stage of conventional die-casting molds. Due to the thinner fan blades and higher rib position characteristics, the stability of magnesium alloy fans in the die-casting production process is not easy to control. Therefore, it is more difficult to require die-casting mold structures, glue feeding methods, and mold materials for magnesium alloy fans. Sometimes the developed mold cannot meet the design requirements of the fan, for example: the blade is thin, the ribs are high, which makes filling extremely difficult, the product cannot be removed from the mold normally, the mold structure cannot meet the mass production, the mold life is short, the prod...
