一, mold basic Knowledge:
1, 引言
我们 day production, active in use to various tool and product, large to machine 床 底 base/seat, machine outer housing/shell, small to 一 胚头螺 filament, 纽扣以 and various use electrical appliances outer housing/shell, and mold has 密切 关系. mold 形状决定 this product outer 形, mold processing quality and degree 也就决定 this product quality. is various product 材质, appearance, specifications and applications different, mold separation is 铸造模, 锻造模, pressure 铸模, pressure and other non plastics mold, and plastics mold.
in recent years, plastics industrial speed development and general purpose and engineering plastics in strong/high degree and degree and other 方面 不断 improve/increase, plastics products application scope in expand large, 如: use electrical appliances, device table/sheet, construction device 材, automotive industrial, day use and other more field/area, plastics products ratio/proportion positive increase. design combined plastics parts can more metal parts. industrial product and day use product plastics trend upper rise.
2, mold generally 定义: in industrial production in, use various pressure machine and in pressure machine upper specialized tool, through pressure metal or non metal material made 出 需形状 parts or products, this type of specialized tool is mold.
3, injection molding process 说明: mold is types production plastics products tool. it 由几组 parts separation formed, this combined inner has molding mold cavity. injection molding 时, mold in injection molding machine upper, melt plastics by molding mold cavity inner, in inner cooling type, rear upper lower separation 开, ejection system will products from mold cavity ejection mold, most rear mold again combined lower one-time injection molding, injection molding process is ring 进行.
4, mold generally classification : can separation is plastics mold and non plastics mold:
（1） non plastics mold has: 铸造模, 锻造模, pressure 模, pressure and other.
A．铸造模—— water leading, iron 平台
B．锻造模—— automotive 身
C．冲 pressure 模——计算 machine sheet/plate
D． pressure 铸模—— ultra- alloy, 汽缸体
（2） plastics mold according to production process and production product different also separation is:
A． injection molding 模—— electrical machine outer housing/shell, 键盘按钮（ application most 普遍）
B．吹 gas 模——饮 material bottle
C． pressure shrink molding 模—— electrical 木开关, 科学瓷碗碟
D．转移 molding 模——集 formed electrical products
E．挤 pressure molding 模——胶 water tube/pipe, plastics bag
F． hot molding 模—— transparent molding packaging outer housing/shell
G．旋转 molding 模—— soft 胶洋娃娃 toys
◆ injection molding is plastics processing in most using/adopting methods . 该 methods suitable for full thermoplastic property plastics and separation hot solid property plastics, made plastics products amount large is its it molding methods 望尘莫 and, as is injection molding processing main/primary tool injection molding mold, in quality degree, manufacturing cycle and injection molding process in production efficiency and other water high low, effect/influence product quality, output/production volume, cost and product more new, meanwhile 也决定 enterprise in market competition in reaction can force and speed degree.
我司 product molding full using/adopting injection molding.
◆ injection molding mold is dry block sheet/plate combined various parts formed , basic separation is:
A molding plant/unit （凹模, 凸模）
B plant/unit （导柱, sleeve/set ）
C solid plant/unit （工字 sheet/plate, 码模坑）
D cooling system （运 water 孔）
E temperature system （ add hot tube/pipe, hot 线）
