Abstract
The invention discloses a plastic injection mold. The plastic injection mold comprises an upper mold seat, a lower mold seat and a cavity formed between the upper mold seat and the lower mold seat, and further comprises a push plate. The push plate is arranged on the upper mold seat and/ or the lower mold seat, and the edge of the push plate constitutes one part of the wall of the cavity. A braking air cylinder used for prohibiting the motion of the push plate is fixedly connected to the push plate, wherein the motion can be in the form that the push plate moves away from the cavity and in the form that the push plate moves towards the cavity. The push plate is further provided with a positioned block, and the lower mold seat or/ and the upper mold seat is provided with a positioning groove, wherein the positioned block is nested into the positioning groove when the upper mold seat and the lower mold seat are coupled together. The plastic injection mold is simple in structure, the cavity sealing performance is good during mold coupling, and therefore the purposes of improving demolding efficiency and optimizing demolding quality are achieved.
