PURPOSE:To adjust press contact force to an arbitrary value by regulating the cam curve of a second cam, by applying the press contact force to the nozzle by a second cam and a spring so as to contact said nozzle with the mold under pressure and making the force allowing the nozzle to contact with the mold under pressure being maintained always constant. CONSTITUTION:A cam driver 11 is allowed to advance by a motor M and brought into contact with a first cam C1 to allow an injection apparatus 1 to advance and a nozzle 3 is brought into contact with a mold 4. The cam C1 revolves while pushes down a cam floor 12 and a brake apparatus 15 is operated to fix a slide base 6. Next, a second cam C2 is revolved by the cam driver 11 to press a spring 8 and the nozzle 3 is brought into contact with the mold 4. |
