The present invention discloses a preform injection mold for an injection blow molding machine, the structure of which comprises a main body, plastic guide blocks and injection molds. Two plastic guide blocks are arranged at the top end of the main body and transversely arranged on the top of the main body. More than ten injection molds are provided, arranged transversely at the front end of the main body in rows of seven. Each injection mold comprises a base, a clamping opening, an injection cavity and an abrasive device. The abrasive device comprises a ventilation groove, branch flow grooves, a guide block and a scraping device. The scraping device comprises a sliding groove, a telescopic tube, a sliding block, a scraping block and a buffer block. The sliding block comprises a clamping rod, a fixed seat, a hollow groove, a return spring and a roller. In the present invention, air flow is introduced into the telescopic tube from the branch flow grooves to inflate the telescopic tube and drive it to extend, so that the sliding block embedded and fixed at the end of the telescopic tube can drive the scraping block to scrape off the excess strip-shaped plasticizer at the side end of the product, avoiding defects in the produced products.
