        模架 in engineering in application 越 越 more, how to 选 准 is issues, 今天我们 summary 模架选取 several 准则, 一起 看看吧.

        模架 generally using/adopting standards and standards parts, this has shrink short manufacturing cycle, reduce manufacturing cost. in production in, according to mold price, structure and processing complex degree 决定.

        遇 to 特殊情况 or 者客户指定 requirements 时, can for 模架 部 separation 形状, dimensions and material more 改, can full heavy new design 模架, this type of lower, 订购模架时需 toward supply provide detailed 模架图, 并注明 订购模架 and standards different 之处.

        确定模架 and parts dimensions

         mold large small main/primary 取决于 plastics products large small and structure, for/regarding mold 面言, in ensure strong/high degree front lower, structure 越紧凑越 good. according to product outer dimensions (平面投影面积 and high degree)以 and product structure 如(侧 toward separation type slip block and other structure), can 确定镶 parts outer dimensions, good parts large small rear, can large 致确定模架 large small

        确定方 iron high degree

        方 iron high degree ensure ejection 行程, rear 留出一定 余 amount (5~10mm), ensure full ejection 时, solid sheet/plate 不至于撞 to sheet/plate or 动模承 sheet/plate.

        模架 overall structure 确定

         in basic 选定模架之 rear, for frame overall structure 进行校核, 看 确定 模架 is combined or 客户指定 injection molding machine, 包括模架 outer large small, thick degree, most large mold opening 行程, ejection methods and ejection and other.

        镶 parts material selection

         mold parts material tool property can main/primary has 四 方面: ① hardness;② wear resistance;③ strong/high degree and tough property;④ corrosion resistant property.

         mold parts material selection main/primary is according to plastics products amount, plastics type 别 确定.

         products is generally plastics 如: ABS, PP, PC and other plastics, usually selection Model/Grade P20 and other type type hard 调质钢, products amount relatively large, selection 淬火回火钢如 Model/Grade H13 and other.

         high light degree or transparent plastics products, 如: PMMA, PS, AS and other plastics or has glass fiber plastics main/primary selection Model/Grade 420 and other type type resistant 蚀不锈钢.

         remove above selection 便准之 outer, also has selection key points can 不知↓↓↓

        1, thick degree H and injection machine combined 距离L for/regarding different Model/Grade and specifications injection machine, different structure 形式 锁模 machine tool has different combined 距离.

        2, mold opening and 定, separation 开 间距 and launch parts 需行程 between dimensions design 时, must 计算确定, injection machine mold opening 行程应 large 于取出塑 parts 需 定, separation 开 间距, mold launch parts must small injection machine ejection liquid pressure 缸 额定 ejection 行程.

        3, selection in injection machine upper 安装安装时需 attention/notes: outer dimensions 不应受 injection machine 拉杆 间距 effect/influence;定位孔径 and ring dimensions combined good; injection machine ejection 杆孔 位置 and ejection is combined 适; nozzle and semi is and mold gate sleeve/set and 凹球面 dimensions versus combined;模架安装孔 位置 and and injection machine 移动模 sheet/plate and solid sheet/plate upper versus 应螺孔 versus 配.

        4, selection 模架应符 combined parts and its molding process technology requirements is ensure parts quality and mold use property can and can property, for 模架组 combined parts force property can, especially is it strong/high degree and rigid degree 进行准确 校核 and 计算, 以确定动, sheet/plate and sheet/plate long, wide, thick degree dimensions, from positive 确 选定模架 specifications.
