A hot chamber die casting machine employing a substantially horizontally arranged charging cylinder and piston. The piston employs a charging head, a sealing head and a rigid member therebetween. The device is arranged to allow access to the piston for changing rings and the like without substantial loss of material from the pot. A safety cover is provided with doors which do not remain open without external support. A cooling system is shown to reduce the temperature of the seal at the open end of the cylinder so that the material within the pot will partially or completely solidify to form an improved seal.
