The invention relates to a skylight sealant leakage-proof glue channel structure and an injection molding method thereof.According to the main technical scheme, the skylight sealant leakage-proof glue channel structure comprises a guide rail, a frame and sealant, the guide rail and part of the structure of the frame are in vertical lap joint, the lap joint portion of the frame is arranged to be a first connecting piece, and a second connecting piece is arranged at the lap joint portion of the frame; a second connecting piece is arranged at the lap joint position of the guide rail, a glue flowing channel groove is formed in the upper surface of the first connecting piece, a glue injection hole used for directly facing the glue flowing channel groove is formed in the second connecting piece, the glue flowing channel groove is used for being filled with sealant, and a glue blocking side wall extending in the length direction of the glue flowing channel groove is formed in the groove edge of the glue flowing channel groove in a protruding mode. When the second connecting piece is in lap joint with the first connecting piece, the lower surface of the second connecting piece extrudes the glue blocking side wall, and the glue blocking side wall conducts adaptive plastic deformation to form a glue blocking structure. The method has the effect of reducing glue overflow.
