Abstract
The utility model provides a silica-gel injection gun barrel, comprising a gun nozzle, a material stopping valve body, a gun barrel and an injection piston, wherein the gun barrel is stepped and is internally provided with a material containing cavity which is internally and coaxially provided with the injection piston for actuating an injection cylinder; and the material containing cavity is fixed with the gun barrel by a gun barrel flange. The silica-gel injection gun barrel is characterized in that the material stopping valve body connected with the other end of the material containing cavity of the gun barrel is internally provided with a material-injection-amount input and output control device and a material-injection-temperature control device connected with the gun nozzle. According to the silica-gel injection gun barrel, on one hand, the external injection cylinder can be effectively controlled to push the injection piston to extrude all liquid silica gel in the gun barrel into a mold, and after the injection action is finished, the material stopping cylinder works to push a valve needle to block an injection channel so as to prevent the liquid silica gel from leaking out when the gun barrel is fed with the liquid silica gel; and on the other hand, since cooling water is introduced into a gun-nozzle cooler, the heat generated when the liquid silica gel passes through the injection channel can be reduced, and the temperature of the liquid silica gel when being injected into the mold can be better controlled.
