Shanghai Daoqin Plastics Co., Ltd.

        我 is from injection molding mold structure design, design home appliances, automotive, electronics product type mold. design water 平不见 very high, is dry active comparison more comparison already. rigid good 闲 没事, large 家共同讨论 lower about/regarding injection molding mold structure design issues.

        首先我们拿 to product rear, need separation 模, most important parts is 先检查 product structure, 包括拔模, thick degree and other type issues. this for/regarding rigid rigid from mold structure design 人 说, can can is comparison difficult. is can can 不知道 how to is comparison combined mold design use product, this 没关系, is day 常积累 一 process. analysis product 拔模, thick, and in direction has 倒扣 方 rear, basic upper already 经知道 mold separation type 面 走 toward, and gate 位置, this most also is need 跟客户确认.

         has 人说, is is analysis good product structure rear, can design mold 呢, 答案当然 is NO. need in design less 走弯路, about/regarding effect/influence mold structure project is need good. specific inner lower: 1, use production injection molding machine and Model/Grade type type, this 确认不 good, 你就没 method 确认你 mold gate sleeve/set 入口直径以 and 定位圈 直径, ejection large small 跟位置, also has injection molding machine can mold inner deep degree, 甚至模架 large small, combined high degree and other and other. 你辛辛苦苦 design good sleeve/set use 油缸抽芯 mold structure, 你也颇 has formed 就感, can mold to that method production, is that has electrical injection molding machine, but also another add in 子, that 时你会 has types 欲哭无泪 感觉. 2, injection molding machine methods, generally commonly used is pressure sheet/plate 码模, filament 码模, liquid pressure 码模, magnetic force and other and other. this good, 你才知道你 design mold 时, to 底需不 need design 码模螺 filament or 者码模槽. 3, rigid 才我们 analysis rear product issues 点, and product 夹线, product material and shrinkage rate. need 想当然 认 is PP plastics shrinkage rate 就一定 is 1.5%, this need 跟客户确认 good, need 知道他们 most used for production material is what grade, has has add what modified material and other and other.

         has conditions 时, most good can product assembly 关系以 and product applications and other and other, this for/regarding will mold structure design is non has 帮助. is understanding this, 你就知道 which is appearance 面, which is non appearance, which 方 拔模角 degree is can add large, which is can 改. 甚至包括一 product structure, if understanding product assembly 关系以 and applications, 你就知道 which structure is can or formed another types simple 形式. need 牢记, mold process is complex issues simple process. to 一 人以做 一 sleeve/set more more complex structure to 骄傲自豪, that is non 常 无知. is very more product engineering can can due to experience issues, design 一 不太 combined structure, if as is lower 游工序, can 帮他们指 positive 话, can can 永远都觉 that design is issues. that product engineering 师 进步就会 non 常 缓 slow.

         mold water outer parameters, outer parameters, electrical outer parameters, gas outer parameters. has in design front understanding this requirements rear, can has property design water 路油路 gas 路, to 时辛辛苦苦 design good mold, rear 发现客户 need in mold internal 串联油路, that again 改动, 估计会累 semi 死, is water 路, 顶杆, what good easy good 位. this design generally is ensure 油路, is need distribution balanced, need ejection mold structure, if 油路不 balanced 话, ejection as has rear, easy ejection balanced. 当然也 can using/adopting gears separation device,但 that more complex. its is water 路, is water need ensure cooling 效果, distribution 不均会 effect/influence product quality and mold lifespan. most rear is gas electrical 路. in mold upper 放置顺序 is, most 靠近TOP direction is electrical 路, rear is water 路, gas 路, most lower is 油路接头.

         its it 未尽事项. this rear, 我们就 can design mold. is separation 模, this process is large comparison process. is separation has formed 就感. separation type 面 原则就 is simple good, can tensile 出 坚决不扫描, or use its it high grade 命令. its separation type need has large 局观, amount separation type 面, need 搞 七七八八, if is precision mold, that 0.1~0.5 插穿位 can 避免 就 need 避免. another separation type also need 遵循一 原则, is amount product trend 做. that 样做出 separation type 面才会beautiful. 串插一句题 outer 话, in 学习三维 soft parts 时, need 切记, 每 命令 principle 都弄明白, that 你就知道 in what can use to that 命令. very more important is 你不会 use soft parts, is 你不会 active active use soft parts. 同样一 命令, has experience has very multiple active use method, this 点体现 in UG upper is most obvious. 一句话, important is 思路, is tool 本身. in separation type 面 时候, need 知道, 插穿面 角 degree can large large, 碰穿面 面积 can large large, 拉出 枕位 can wide wide. need separation 考虑你现 in upper this separation type will mold rear, workshop negative 责飞模 师傅会不会骂你就行. if 你觉 不会挨骂, that 就OK, 继续进行, will true by 骂, this is experience.

         in separation type meanwhile is need slip block 跟斜顶 排布, is that need and to separation type 面 改动. type slip block structure is 三角函数关系, this 没事自己 more 算算就行, need ensure 斜导柱 角 degree need large, amount to 30 degree below/following. 斜导柱 selection 原则就 is can coarse coarse, small gas, is 斜导柱 is need force. another slip block separation very more structure, 例如, upper slip block, lower slip block, inner slip block, 油缸抽, front slip block, slip block belt/tape slip block, slip block belt/tape 反顶, slip block belt/tape 斜顶, and other and other, this structure is separation utilizing 三角函数关系式, 目 就 is is achieve product demolding, and mold positive clamping as. slip block 计算公式各 large forum has detailed introduction, 我就不 in 此赘述.

         its is 斜顶, comparison active, type 斜顶 角 degree need large, amount need ultra- 15 degree, 当然你 non need 做20 degree 也行, lifespan very difficult ensure, but also as very 不顺畅, specific principle 参照三角函数 and force 学. 斜顶 形状 has very more 演化形式, 例如, upper 坡斜顶, lower 坡斜顶, 歪脖子斜顶, 镶拼斜顶杆 large 斜顶, 镶拼圆杆 large 斜顶, 镶拼挂台 small 斜顶, block lower 面走斜顶, slip block upper 走斜顶, upper 走斜顶, upper belt/tape 反顶, and other and other, this has structure is 一 目, utilizing 三角函数 product 倒扣做出. can 见, good 三角函数 is more important 啊! therefore various structure, is 人想出, large can separation 发挥你 想象 force, tube/pipe what structure can 随便想, good, large design, good has new 发明呢, design rear, need lower 三角函数 关系, is 实际模拟 lower mold clamping as, and lower in injection molding 时会不会 has issues and other and other.

        说 说, separation separation good. lower is mold structure 排位, this inner is need 理清头绪, according to product 实际情况, selection different type type mold structure, 例如, sheet/plate 模, sheet/plate 模, hot runner, IMD, IML, di color, and other and other. has mold structure type type is is can very good achieve product amount 产而服务. in selection 模架时, 我们就 need separation rigid to that 4点 precautions.

        选 good 模架我们就 need mold 镶拼, 镶拼 原则就 is processing, 节省材 material, product molding, ratio gas and other and other. mold upper in especially thin 方, need mono 独镶拼出, easy will more 换. in 镶拼 时候 need separation 考虑镶 parts strong/high degree, processing property, and will water can design property. 镶拼完 rear, need add standards parts. add standards parts 原则就 is focus/key point rear local, amount balanced for 称. generally is need add 顶杆, add 顶杆时一定 need water 路 排布. generally lower, need excellent 先考虑顶杆 排布, rear large design water 路, rear again according to 实际情况 adjustment water 路顶杆, make 两者达 to balanced. add ejection 原则就 is force large 方, another need add in product 楞, 台, and other strong/high degree structure comparison good 方, 以免顶白 or ejection balanced. water 路 原则就 is add ejection 原则, is generally 讲, product force large 方也就 is product hot 点, need add strong/high cooling 部位, this need adjustment good. to is use also is use block or sheet/plate, need specific issues specific analysis. this need combined product structure features analysis, ratio product easy viscous front 模, need need need rear add 倒扣, or front add ejection, this is however 然 事情, very more 朋友都不会想 comprehensive is what causes 呢, that also is is has for product structure analysis separation, has 实际考虑 lower product in injection molding process in 状态. this is issues key/critical. water add 完, lower is that 乱七八糟 standards parts, large in add 时候尽 amount for balanced is.

        整 sleeve/set mold design formed rear, need below/following 几项检查, is block analysis, has has 倒扣 方, its is mold parts dry 涉检查, heavy in heavy. in soft parts has this function, very. rear is mold clamping as 模拟, again simple mold need 自己不 is 太清晰, 就一定 need 实际模拟 lower, another is mold parts can processing property and mold assembly process, 别辛辛苦苦 design 出 巧妙 structure, 理论计算也没 issues, processing 完, 结果装不进, or good assembly.

        至此, can 恭喜你, large process/workflow already 经结束. its mold design is 充满 矛盾 事情. design 完美, mold use high, design simple 一, can can product need or mold strong/high degree, use lifespan has effect/influence. therefore mold design has for. need good that balanced 点, design mold is formed 功. therefore, design structure 未必都适 combined 你. need above mold design key points, large can design comparison combined mold structure.
