    • The injection molding machine comprises the closing mechanism 5 having the nozzle touch member 3 to close the tip opening 1a of the nozzle 1 and the electric heater 6 to regulate the temperature of the nozzle touch member 3. The closing member 5 is constituted in such a manner as the arm 13 is pivotally supported on the jacket cover 11 mounted on the nozzle 1, the cylinder 7 is mounted on mounting member 14 provided at the tip of the arm 13, and the nozzle touch member 3 is supported at the tip of the piston rod 7a. The electric heater 6 is arranged around the nozzle touch member 3. When the arm 13 is rotated from the retreated position R to the closed position C by the actuation of the rotor 8, the nozzle touch member 3 is faced to the tip opening 1a of the nozzle 1, and by extending the cylinder 7, the nozzle touch member 3 regulated to the temperature suitable for the resin material by the electric heater 6 closes the tip opening 1a from its front surface.
    • 注射成型机包括具有喷嘴接触部件3以关闭喷嘴1的前端开口1a和电加热器6的关闭机构5,以调节喷嘴接触部件3的温度。封闭部件5构成为 当臂13枢转地支撑在安装在喷嘴1上的护罩盖11上时,气缸7安装在设置在臂13的尖端的安装构件14上,并且喷嘴接触构件3被支撑在 活塞杆7a。 电加热器6设置在喷嘴接触部件3周围。当通过转子8的动作使臂13从退避位置R旋转到闭合位置C时,喷嘴接触部件3面向 喷嘴1,并且通过延伸气缸7,通过电加热器6调节到适合于树脂材料的温度的喷嘴接触构件3从其前表面封闭尖端开口1a。
