PURPOSE: A pneumatic and hydraulic rubber injection molding device is provided to prevent heat loss by installing first and second insulation plates on first and second heat plates. CONSTITUTION: A pneumatic and hydraulic rubber injection molding device comprises a frame(10), a body frame(20), first and second mold frames(30,40), an injection core, elevating devices(60), and a booster cylinder. The body frame is installed on the top end of the frame, and a shaft is installed inside thereof. First and second molds of the first and second mold frames process the bottom and top surfaces of an object. The injection core comprises a core unit(51) and a core unit elevator(52). The core unit is installed on the top end of the body frame and presses the object. The core unit elevator elevates the core unit. The elevating devices are powered by the booster cylinder and elevate the second mold frame. The booster cylinder is connected to the core unit elevator and the elevating devices.
