Technical Field

[0001] The utility model belongs to the technical field of hot runners, and in particular relates to a high-efficiency processing device. Background Art

[0002] Hot runner is a heating component system used in injection molds to inject melted plastic particles into the mold cavity. Hot runner molds are a new structure that heats the runners and channels of traditional molds or three-plate molds, so that the runners and channels do not need to be removed during each molding. The hot runner valve needle is a very common component in the hot runner system, so the processing of hot runner valve needles is also frequently encountered in industrial production and processing.

[0003] The processing of hot runner valve needles includes many steps, one of which is to polish and grind the surface to make it smooth. However, the existing grinding device requires manual hand-held clamping of the hot runner valve needle during the processing operation, and then grinding with a grinding belt.
