Intramode butt fusion type secondary processing method

The invention relates to an intramode butt fusion type secondary processing method comprising a movable mould, an auxiliary mould driving device, an auxiliary mould, a heating butt fusion device and a fixed mould. The intramode butt fusion type secondary processing method is characterized in that after the movable mould, the auxiliary mould and the fixed mould are closed, an injection molding machine performs an injection action and opens the moulds to necessary distances after the injection procedure, the movable mould drives the auxiliary mould to match a next working station through the auxiliary mould driving device, and then, the heating butt fusion device enters the mould region to heat originally separated and different component products, the heating butt fusion device retreats, and finally, the injection molding machine closes the moulds to fuse the originally separated and different component products together so as to finish the intramode butt fusion type secondary processing procedure and assemble
