Shanghai Daoqin Plastics Co., Ltd.

         injection molding machine mono 元四 部 parts technology requirements.

        1.射嘴

        直通式 nozzle is application relatively nozzle, its features is nozzle 球面直接 and mold sleeve/set 球面接触, nozzle semi and runner ratio mold need small, injection 时, high pressure melt 直接经 mold system mold cavity, speed degree fast, pressure loss small, manufacturing and 安装均 relatively 方便.

        锁闭式 nozzle main/primary is solution 直通式 nozzle issues, suitable for low degree polymer (如PA) processing. in 预塑时 can nozzle runner, anti melt phenomenon, injection also can in injection pressure function lower 开启, make melt mold cavity.

          2. injection 油缸

        工 as principle is: injection 油缸进油时, active belt/tape active and its 置于推 force base/seat inner bearings, screw front or rear 退. through active 塞杆头部 螺母, can for 两 平行 active 塞杆 轴 toward 位置以 and injection screw toward 位置进行同步 adjustment.

        推 force base/seat injection 时, force base/seat through force 轴推动 screw injection;而预塑时, through 油马达驱动推 force belt/tape screw achieve 预塑.

         3. base/seat 移油缸

        当 base/seat 移油缸进油时, achieve injection base/seat front or rear as, ensure injection molding nozzle and mold sleeve/set 圆弧面紧密 接触, generate can melt injection base/seat pressure.

        4. for injection parts degree requirements

        射嘴 assembly rear, overall injection parts need machine upper, must ensure nozzle and mold sleeve/set 紧密 接 combined, anti material.

         requirements make injection parts in and its clamping parts in 心线同心; is ensure injection screw and material inner 孔 配 combined degree, must ensure injection 油缸孔 and material 筒定位 in 心孔 平行 degree and in for degree.

         for machine 讲, base/seat 移油缸两 导 toward 孔 平行 degree and for its in for degree must ensure.
