Description

Injection molding machine nozzle speed regulating device Technical Field The utility model belongs to the technical field of injection molding machine nozzles, and particularly relates to a nozzle speed regulating device of an injection molding machine. Background Injection molding machine nozzle timing devices are an auxiliary device that enables fine adjustment of the injection molding process by controlling the melt flow rate in the nozzle region, which is generally based on the flow characteristics of the melt in the nozzle channel, directly interfering with the shear rate and pressure distribution of the melt by changing the geometry of the nozzle channel or applying an external force field. By accurately controlling the flow rate of the melt, the method can avoid flash and air lines caused by too high flow rate or insufficient welding lines and filling caused by too low flow rate, and in a multi-cavity die, the speed regulating device can also compensate the flow resistance difference of each cavity, so that the uniformity of the size and the performance of the product is ensured.
