Design principles of cooling system for injection Mould

The design of cooling system needs to consider the structure of die, the size and thickness of plastic parts, the position of insert, the position of weld mark, etc.1) the thickness of plastic parts is uniform, the distance between cooling channel and cavity surface is equal, that is, the arrangement of cooling channel is consistent with the shape of mold cavity, the cooling channel at the wall thickness of plastic parts should be close to the cavity, and the distance between cooling channel and cavity surface should be small in order to strengthen cooling.The distance between the cooling channel and the surface of the cavity is larger than that of 10mm, which is 1 ~ 2 times of the diameter of the cooling channel.2) the diameter of cooling channel is as large as possible and the number of cooling loop is as large as possible, so as to ensure uniform cooling.
