         injection molding mold cooling water is 经常发生, causes very more, main/primary has below/following several 方面:

        ① most more in mold cooling water tube/pipe 接头处, 如发现漏 water, in tube/pipe 接头 螺纹 upper 缠绕密封 belt/tape, rear 拧紧.

        ② due to long molding conditions lower, mold inner anti water 圈会破 loss, in O形 anti water 橡胶圈容 easy hard and cracking, 导致漏 water. has anti water 圈安装 defect 也会引起密封失效. generally 需定期检查密封圈 安装位置 and property can.

        ③ cooling water 孔 孔壁破 loss. use new mold 时经常会发生 this type of 情况, design thick is 足够, due to processing or rear processing formed 孔壁穿破. more 数情况 lower, water water can again use.

        ④ cooling water 孔 检修. cooling water inner very easy water 垢, retardant hot, heavy make water 路不通, need 定期检修. for/regarding water 孔, can ratio cooling water 孔直径 small 0.5mm 钢棍, use 锤子敲击, remove water and iron 锈. for/regarding mold inner cooling water tube/pipe, separation understanding mold, remove iron 锈.

        检修之 rear 应进行漏 water experiment/testing, using/adopting pressure toward water inner water, in 2MPa pressure lower maintain 5min, through water pressure is reduce water is water. water can use 橡胶, soft and other elastic property material machine solid methods 堵塞, also can use normal temperature solid type silicon as is 封堵材 material.

        ⑤定期检修 add hot tube/pipe and decrease pressure and utilizing. add hot tube/pipe is has 效 传 hot parts, for fine deep structure type cooling non has 效. in cooling water easy through 部位, mono toward add hot tube/pipe can decrease/reduce water. in addition, using/adopting decrease pressure cooling water, is anti cooling water methods.
