The invention provides a feeding and collection device for an injection molding machine. The feeding and collection device comprises the injection molding machine. The lower end of the injection molding machine is provided with a feeding groove. The lower end of the feeding groove is provided with a collection frame. The upper end face of the collection frame is movable. The right side of the collection frame is provided with an arrangement discharging rail. A material push air cylinder is arranged beside the arrangement discharging rail. A recycling rail is arranged below the arrangement discharging rail and connected to the collection frame. The tail end of the arrangement discharging rail is provided with a blocking air cylinder. Plastic products manufactured through the injection molding machine are placed on the collection frame through the feeding groove, moved through the upper end face of the collection frame and screened through the arrangement discharging rail so that the plastic products in the right direction can be arranged into a row, and the plastic products in the wrong direction can be removed, the working efficiency of discharging is improved, and therefore the plastic products can be used conveniently in the next process; and a material overturning rod is arranged to guarantee that most of materials are in the normal direction, it is avoided that batches of products in the wrong direction enter the collection frame, and working efficiency is improved.
