Abstract

This invention provides a plastic product injection molding device, including a base plate. A bottom mold is fixedly mounted on the top of the base plate. A first groove is formed on the top of the bottom mold, and a second groove is formed inside the bottom mold. A threaded rod is movably mounted inside the second groove, and a nut seat is movably mounted outside the threaded rod. A lifting plate is fixedly mounted on one side of the nut seat, and a support rod is fixedly mounted on the top of the lifting plate. One end of the support rod extends into the first groove and is fixedly connected to the bottom of the support plate. After injection molding is completed, by rotating the threaded rod, the nut seat drives the lifting plate to move vertically up and down. This causes the lifting plate to drive the support rod and the support plate to move vertically up and down, thus ejecting the molded plastic product from the first groove. This facilitates demolding of the molded plastic product, reducing the tediousness of manual demolding and achieving rapid demolding.
