          as 者: 邓 formed 林, automotive mold expert, has 《 automotive injection molding mold design key points and 实例》

         trend

        随 electric vehicles and 无人驾驶 technology and new can automotive to, automotive light amount design will is automotive design trend, can make automotive light amount design is 现实 必然 is plastics. plastics a large amount of used for automotive industry, will for plastics industry and automotive injection molding mold industry belt/tape new history machine 遇.

         inner outer formed

        1. automotive inner table/sheet formed

         main/primary 包括主仪 table/sheet formed, table/sheet tube/pipe formed, table/sheet formed.

        2. automotive inner sheet/plate formed

        3. SUV车 type inner sheet/plate formed

        4. automotive inner 饰门护 sheet/plate formed

        5. automotive 顶棚总 formed

        6. automotive front rear 保险杠总 formed

        7. automotive rear 背门护 sheet/plate formed

        8. automotive sheet/plate formed

        9. automotive tool formed

         inner outer commonly used material

         automotive injection molding mold in inner outer upper ratio/proportion

         automotive industrial development rear is automotive mold industrial development. especially is in recent years, world automotive mold industrial development more is day new month 异, automotive for mold demand amount 也越 越 large. in new in, need automotive injection molding mold 约500副. in automotive industrial 发达国家, automotive product market has rate already ultra- 60%, but also this trend also in rise. can injection molding mold in automotive mold specific gravity most large, important property 不言而喻.

         automotive inner outer injection molding mold technology

         automotive injection molding mold and its it injection molding mold has essence difference, has its very more features. due to automotive injection molding mold add value generally relatively high, therefore very more technology (如顺序阀 hot runner control technology, inner separation type technology, low pressure injection molding technology and other)都 excellent in automotive injection molding in to development and application.

        1. 顺序阀 hot runner control technology （SVG technology ）

        顺序阀 hot runner control technology (SVG technology) is types new type grade control hot runner technology, through control 按顺序进胶, solution more 点同步进胶 product appearance defect difficult 题. can has 效避免 automotive inner outer trim parts 出现熔接痕, gas and other defect, decrease/reduce long, reduce molding pressure, in appearance requirements automotive inner outer trim parts upper 发挥 巨 large function.

        2.  low pressure di injection molding mold technology

         low pressure di injection molding mold, also low pressure injection molding mold, is types new type injection molding mold technology, will 传统 依靠手工包覆, anionic cationic true 空吸附 parts, one-time property in mold inner injection molding formed. low pressure injection molding mold main/primary principle is: injection molding pressure relatively low plastics in upper flow, mold opening need will to front 模挂针 upper, rear again clamping, injection molding, most rear parts. using/adopting this type of technology production product, due to surface has 一层特殊 soft material, is decoration property, 手感, property large large improve/increase. low pressure injection molding mold technology widely used in in high automotive upper, generally used for automotive bag skeleton/framework, automotive ABC柱 and other parts upper.

         low pressure injection molding mold main/primary principle is injection molding pressure relatively low in upper flow, mold opening need 先 布挂 to front 模挂针 upper, clamping, injection molding, rear parts.

        3. automotive 保险杠 inner separation type injection molding mold technology

         in automotive injection molding mold in, for automotive 保险杠 product, mold design usually using/adopting inner separation type technology. its advantages is separation type 夹线隐藏 in 保险杠 non appearance upper, in automotive upper assembly rear to appearance 夹线, effect/influence product appearance. this type of technology in difficult degree and structure upper need ratio outer separation type 保险杠 complex, technology 风险也 relatively high, mold cost and mold price high outer separation type 保险杠 very more, appearance 美观, in in high automotive in by application.

        如 lower 图 示, product using/adopting 直顶+斜顶 machine 构进行 demolding.

         lower 图 示 product 底部蓝 color using/adopting in large upper design structure, make product in ejection anti product ejection 时同斜顶走.

        此侧倒扣 using/adopting upper structure:

        扣位 using/adopting in upper 做隧道 elastic block structure demolding:

         ejection machine separation grade ejection:

        (1)第一 grade ejection using/adopting 4 油缸 ejection front 模同步运动 ejection 60MM, 4 拉钩 is machine 构;

        (2)第二 grade ejection rear 油缸继续 ejection 70MM;

        (3)第三 grade ejection use 2 small 油缸做二次 ejection 30MM, 方便取 parts.

         is ensure mold opening 时斜顶跟 front 模一起同步运动,以 make product deformation demolding, ejection machine front 模同步运动60MM rear, front / rear separation separation 离, this 样保护 mold,也 ensure product by 拖伤!
