The invention relates to the technical field of blow molding of vehicle lamp shades, in particular to a blow molding machine for producing vehicle lamp shades and a use method thereof. It comprises a table frame plate which is hollow inside and provided with a through slot in the middle, a breathable plate clamped inside the through slot and flush with the top surface of the table frame plate, a molding assembly longitudinally slidably arranged above the outside of the table frame plate for lamp shade molding, and a blowing assembly longitudinally slidably arranged below the outside of the table frame plate capable of delivering hot air into the molding assembly through the breathable plate. A softened plastic sheet to be blow-molded can be placed on the top surfaces of the table frame plate and the breathable plate. The invention enables the lamp shade taken out of the blow molding machine to already have a rim of specified size, avoiding subsequent rim cutting and reducing actual production steps of vehicle lamp shades. At the same time, hardened plastic sheets are recycled, that is, excess softened plastic sheets and hardened plastic sheets are separately cut and recycled, facilitating subsequent reuse and avoiding unnecessary waste of plastic sheets.
