Abstract

This utility model discloses an injection mold, including a lower mold base and a module. The lower mold base has a mold groove. The top of the module is fixedly connected to a mounting plate. The top of the mounting plate is provided with a hydraulic rod. The top of the hydraulic rod is fixedly connected to a mounting bracket. The bottom of the mold groove has an exhaust chamber. After injection molding, the hydraulic rod drives the mounting plate and the module to move upward. The mounting plate drives the second connecting rod to move upward. The second connecting rod drives the second movable plug to move upward through the first connecting rod. In order to maintain the pressure balance of the air supply chamber, the exhaust chamber and the inner cavity of the fixed pipe, the air pressure pushes the first movable plug to move upward. The first movable plug drives the vertical rod and the limiting plate to move upward. The first spring is compressed and deformed. The upward movement of the first movable plug ejects the molded finished product, thereby achieving demolding without the need for tools and avoiding damage to the finished product.
