        冲 pressure processing is large amount parts molding production use process 之一. mold fault/failure is pressure production in most easy issues,常常造 formed 停产, effect/influence product production cycle. therefore,必 must fast to mold fault/failure causes, combined repair.

        1 mold loss bad

         mold loss bad is mold cracking, 折断, and other,处理 mold loss bad issues,必需 from mold design, manufacturing process and mold use 方面寻找 causes. false 如引起异 material mold, made parts heavy 叠, waste material retardant and other 情况未 and 时处理,继承 processing production,就 very light easy loss bad mold material sheet/plate, 冲头, lower sheet/plate and 导柱. elastic force design small or and other high sleeve/set and other high,会 make elastic fracture, material sheet/plate 倾斜.造 formed heavy 叠冲 打, loss bad parts. false mold temperature high,淬火 methods and time 不公道,以 and 回火次数 and temperature degree, selection 不当,都会导致 mold 进入冲 pressure production rear loss bad. solid 定不当 or filament strong/high degree 不够.会导致冲头掉落 or 折断. as high degree adjustment low, lubricated 不足. usually, mold material hot process for its effect/influence very large. material dimensions or deep degree design 不够, light easy make 槽孔梗 retardant,造 formed material sheet/plate loss bad. mold use 时, parts 位置, direction and other 安装错误 or 螺栓紧 solid good.

        2 卡模

        引起卡模 main/primary causes has: mold toward positive 确, 倾斜. 否则, will expand large fault/failure,导致 mold loss bad. formed mold deformation,例如模 base/seat, sheet/plate hardness, thick degree design small, light easy outer force deformation; mold 位置安装不准, upper lower 模 定位误差 ultra- 差. this 时应进步冲头 strong/high degree, reinforcement material sheet/plate 引导保护.

         or pressure machine degree 太差, make mold generate dry 涉;冲头 strong/high degree 不够, large small 冲头位置太近, make mold toward force balanced. pressure process in,一旦 mold clamping active,甚至卡死,就必需立刻休止出产,找出卡模 causes, troubleshooting fault/failure.

        3 mold loss bad and repair

        冲 pressure production mold use degree high. usually mold made parts 总本钱 1/5-1/4. one-time property use degree ultra- 冲模原造价 70%, or mold lifespan already 近. mold repair technology complex, use degree large, difficult degree large make repair cycle long,严峻 effect/influence pressure positive 常出产,应 selection front 失效报 waste, heavy new manufacturing mold. generally 说.

         mold loss bad rear, also has repair and waste selection 题目. is. therefore, and repair mold, anti mold loss bad, can large large reduce pressure production mold use. mold parts loss bad, has 时凸, meanwhile loss bad. this is due to, remove mold manufacturing difficult degree large, cost high outer. pressure mold non abrasion loss 失效,例如 non parts bad.

         in positive 常情况 lower,冲 pressure processing mold main/primary 失效形式 is amount abrasion loss. from new mold manufacturing use. 直至冲 made parts ultra- 标, parts dimensions and 形位精 degree ultra- 差,而 mold also can again or 根本无修复价 value,则 mold can waste. from new mold use to 失效报 waste.
