Shanghai Daoqin Plastics Co., Ltd.

        一, made mold 图

         in mold 总装图之 front, made 工序图, need combined made parts and process material requirements. lower 道工序 ensure dimensions, in upper 标写注明" process dimensions "字样. if molding rear remove 修理毛刺之 outer, again 不进行 other machine processing, that 么工序图就 and made parts full same.

         in 工序图 lower most good made parts 编号, 名称, material, material shrinkage rate, ratio/proportion and other. usually 就 工序图画 in mold 总装图 upper.

        绘 made 总装图尽 amount using/adopting 1: 1 ratio/proportion, type 腔开始绘 made, 主视图 and its it meanwhile 画出.

         mold 总装图应包括 below/following inner 容:

         mold molding separation structure

        浇注 system, gas system structure 形式.

         separation type and separation parts methods.

         outer structure and has parts, 定位, toward parts 位置.

        标注 type high degree dimensions (不 strong/high 求, according to need) and mold dimensions.

        辅助工 tool (取 parts 卸模工 tool, positive tool and other).

        按顺序 will full parts 序号编出, and 填写明 fine table/sheet.

        标注 technology requirements and use 说明.

         mold 总装图 technology requirements inner 容:

         for/regarding mold certain system property can requirements. for ejection system, slip block structure assembly requirements.

         for mold assembly process requirements. mold assembly rear separation type 面 贴 combined 面 贴 combined 间隙应不 large 于0.05mm mold upper, lower 面 平行 degree requirements, 并指出由 assembly dimensions and for dimensions requirements.

         mold use, methods.

         anti oxidation 处理, mold 编号, 刻字, 标记, 油封, tube/pipe and other requirements.

         has mold trial and 检验方面 requirements.

        由 mold 总装图拆画 parts 图 顺序应 is: inner rear outer, complex rear simple, molding parts, rear structure parts.

         requirements lower:

        图形 requirements

        一定 need ratio/proportion 画, 允许放 large or shrink small. selection combined 理, positive 确, 布置 当. is make processing patent easy 看懂, assembly, 图形尽 can can and 总装图一致, need 清晰.

        标注 dimensions requirements 统一, in, has 序, 完整

        标注 dimensions is: main/primary parts dimensions and 出模斜 degree, again 标注配 combined dimensions, rear full dimensions. in non main/primary parts upper 先标注配 combined dimensions, rear full dimensions.

         surface coarse degree

         application most more types coarse degree 标于图纸 right upper 角, 如标注" its 余3.2. " its it coarse degree in parts surface separation 别标出.

         its it inner 容

        例如 parts 名称, mold 图号, material grade, hot and hardness requirements, surface treatment, ratio/proportion, dimensions processing degree, technology and other need positive 确填写.

        二, for, 审图

         mold and its parts and parts 图纸 关系

         mold and mold parts 材质, hardness, dimensions degree, structure and other is combined parts requirements.

         plastics made parts 方面

         plastics material flow, shrink 孔, 熔接痕, 裂口, demolding degree and other is effect/influence plastics made parts use property can, dimensions degree, surface quality and other requirements. design has 无不足, processing is simple, molding material shrinkage rate selection is positive 确.

         molding equipment 方面

         injection amount, injection pressure, clamping force 够不够, mold 安装, plastics made parts 南芯, demolding has issues, injection machine nozzle and sleeve/set is positive 确 接触.

         mold structure 方面

         separation type 面位置 and processing degree is meet/satisfy need, 会不会发生溢 material, mold opening rear is can ensure plastics made parts in has ejection plant/unit mold 一边.

         demolding methods is positive 确, 推广杆, tube/pipe large small, 位置, amount is combined 适, sheet/plate 会不会 by type 芯卡住, 会不会造 formed scratch molding parts.

         mold temperature degree adjustment 方面. add hot device rate, amount; cooling flow 线路位置, large small, amount is combined 适.

        处理 plastics made parts made methods, 脱侧凹 machine is 否恰当, 例如斜导柱抽芯 machine in slip block and is versus dry 扰.

        浇注, gas system 位置, large small is 否恰当.

         design 图纸

         assembly upper mold parts 安置部位 is 否恰当, table/sheet is 否清楚, has 无遗漏;

         parts upper parts 编号, 名称, made as amount, parts inner made also is outer 购, is standards parts also is non standards parts, parts combined 处理精 degree, molding plastics made parts high degree dimensions 处 修 positive processing and amount, mold parts material, hot 处理, surface treatment, surface processing degree is 否标记, 叙述清楚.

         parts main/primary parts, molding parts as dimensions and combined dimensions. dimensions 数字应 positive 确无误, need make production 者换算.

        检查 full parts and 总装图 视图位置, is positive 确, method is combined made 图国标, has 无遗漏 dimensions.

        校核 processing properties

         has parts structure, 视图画 method, dimensions 标'' and other is has processing

        复算辅助工 tool main/primary as dimensions

        专业校 for upper design 者自我校 for project 进行;但 is need heavy structure principle, process property can and as safety 方面. need 先消化图形, 按国标 requirements 描绘, full dimensions and technology requirements. rear and 签字.

         good 底图交 design for 签字, 习惯做 method is tool manufacturing mono has technology 人员审查, 会签, manufacturing process property, rear can 送晒.

        编写 manufacturing process sheet/slice

        由工 tool manufacturing mono technology 人员编写 manufacturing process sheet/slice, and is processing manufacturing good 准备.

         in mold parts manufacturing process in need add strong/high 检验, focus/key point in dimensions degree upper. mold 组装完 formed rear, 由检验员 according to mold table/sheet 进行检验, main/primary is mold parts property can is good, has this can ensure mold manufacturing quality.

        三, mold trial and 修模

         although is in molding material, molding equipment 时, in process conditions lower mold design, is 人们 认识往往 is 不完善, therefore must in mold processing formed rear, mold trial experiment/testing, molding made parts quality how to. 发现总 is rear, troubleshooting property 修模.

        塑 parts defect phenomenon types type more, causes very complex, has mold causes, has process conditions causes, 二者往往交 in 一起.

         in front, according to parts defect phenomenon 实际情况, fine analysis research, 找出造 formed parts defect causes rear remedy methods. is molding conditions easy 改变, therefore generally method is more molding conditions, more molding conditions can solution issues 时, 才考虑修理 mold.

        修理 mold more heavy, has separation can light 举妄动. its causes is 一旦变 more mold conditions, can again as large renovation and 恢复原状.

         parts property can is good, has this can mold manufacturing quality.

        四, 整理资 material 进行归档

         mold experiment/testing rear, 若暂不 use, 则应该完 full scratch remove demolding 渣滓, 灰尘, and other, coating upper or other anti or anti agent, to tube/pipe 场 保 tube/pipe.

         design mold to mold processing formed 功, combined is 止, in 此期间 generate technology material, 例如任务书, made parts 图, technology 说明书, mold 总装图, mold parts 图, 底图, mold design 说明书, 检验记录 table/sheet, mold trial 修模记录 and other, 按规定 add system 整理, 装订, 编号进行归档. this 样做似乎 very 麻烦, is for rear mold, design new mold is very has use 处.
