In this process, the staff does not need to manually demold and remove the molded accessories inside the fixed mold injection molding sleeve 24, thereby achieving the convenience of molding a large number of plastic accessories for medical puncture devices. At the same time, the demolding effect is achieved. When the staff is injection molding the plastic accessories of the medical puncture device, the staff connects the injection liquid pipeline with the first connecting tube 5, and then the injection liquid enters the interior of the injection molding groove 26 through the first connecting tube 5, and then the injection liquid inside the injection molding groove 26 enters the interior of the multiple fixed mold injection molding sleeves 24 through the injection molding connecting tubes 39 on the surfaces of the multiple fixed mold injection molding sleeves 24. In this process, since the multiple fixed mold injection molding sleeves 24 are interconnected with the injection molding groove 26 through the injection molding connecting tubes 39, the injection liquid will be filled into the interior of the multiple fixed mold injection molding sleeves 24, thereby achieving the effect of injection molding the plastic accessories of the medical puncture device.
