A die casting machine has a clamping device and an injection device. The clamping device has a fixed die plate which holds a fixed die, a movable die plate which holds a moving die, an electrically operated die opening and closing-use driving device which moves the movable die plate in a die opening and closing direction, and a clamping cylinder which generates a clamping force. The injection device has a sleeve, a plunger which capable of sliding in the sleeve, an electrically operated injection-use driving device which drives the plunger at least at the time of low speed injection, and an injection cylinder which drives the plunger at least at the time of high speed injection. 1. A molding apparatus comprising: a fixed die plate which holds a fixed die,', 'a movable die plate which holds a moving die,', 'an electrically operated die opening and closing-use driving device which moves the movable die plate in an opening and closing direction and', 'a clamping cylinder which generates a clamping force; and, 'a clamping device which has'} a plunger which is capable of sliding in a sleeve,', 'an electrically operated injection-use driving device which drives the plunger at least at the time of low speed injection and, and', 'an injection cylinder which drives the plunger at least at the time of high speed injection., 'an injection device which has'}2. The molding apparatus according to further comprising a liquid pressure unit which hasa tank for storing a hydraulic fluid,a pump for sending out the hydraulic fluid from the tank,a plurality of valves for controlling the flow of the hydraulic fluid, anda holding base for holding the tank, the pump, and the plurality of valves, whereinthe liquid pressure unit supplies the hydraulic fluid to both of the clamping cylinder and the injection cylinder.3. The molding apparatus according to further comprising a core cylinder for making a core advance or retract to or from a space between the fixed die and the moving die claim 1 ...
