1results about How to "Reduce fluid resistance" patented technology

The utility model discloses a mould insert of variable diameter spiral cooling waterway, including insert body, the insert body inside is equipped with spiral cooling waterway, spiral cooling waterway includes a plurality of spiral watercourse unit along the axial distribution of insert body, adjacent spiral watercourse unit's diameter is different, and spiral watercourse unit's diameter gradually increases or gradually reduces along the cooling liquid flow direction, spiral watercourse unit includes the cooling channel of spiral and is provided with the connecting portion at the both ends of cooling channel, and adjacent spiral watercourse unit is communicated through the connecting portion. Through the spiral watercourse unit of diameter gradual change, realizes the dynamic regulation of cooling liquid flow rate according to the principle of fluid mechanics, and the heat dissipation demand of accurate matching mould different parts is promoted, and the cooling efficiency is improved significantly, and the forming cycle is shortened.
