一般塑料模具由動模和定模兩部分組成,動模安裝在注射成型機的移動模闆上,定模安裝在注射成型機的固定模闆上。在注射成型時動模與定模閉合構成澆注系統和型腔,開模時動模和定模分離以便取出塑料制品。
Generally, plastic moulds are composed of moving and fixed moulds. The moving moulds are installed on the moving moulds of the injection moulding machine and the fixed moulds are installed on the fixed moulds of the injection moulding machine. In injection moulding, the gating system and the cavity are formed by the closure of the movable and fixed moulds, and the movable and fixed moulds are separated when the moulds are opened to remove the plastic products.
模具的結構雖然由于塑料品種和性能、塑料制品的形狀和結構以及注射機的類型等不同而可能千變萬化,但是基本結構是一緻的。模具主要由澆注系統、調溫系統、成型零件和結構零件組成。其中澆注系統和成型零件是與塑料直接接觸部分,并随塑料和制品而變化,是塑模中最複雜,變化最大,要求加工光潔度和精度最高的部分。
Although the structure of the mould may vary greatly due to the variety and performance of plastics, the shape and structure of plastics products and the type of injection machine, the basic structure is the same. The die is mainly composed of pouring system, temperature regulating system, forming parts and structural parts. Among them, the casting system and the forming parts are the parts directly contacted with the plastics, and change with the plastics and products. They are the most complex and most changeable parts in the plastic mould, requiring the highest processing smoothness and accuracy.
澆注系統是指塑料從射嘴進入型腔前的流道部分,包括主流道、冷料穴、分流道和澆口等。成型零件是指構成制品形狀的各種零件,包括動模、定模和型腔、型芯、成型杆以及排氣口等。
The pouring system refers to the runner part of the plastic before it enters the cavity from the nozzle, including the main runner, the cold material hole, the shunt runner and the gate, etc. Molding parts refer to all kinds of parts that constitute the shape of products, including moving die, die setting and cavity, core, forming rod and exhaust outlet, etc.
我國塑料模具在高技術驅動和支柱産業應用需求的推動下,形成了一個巨大的産業鍊條,從上遊的原輔材料工業和加工、檢測設備到下遊的機械、汽車、摩托車、家電、電子通信、建築建材等幾大應用産業,塑料模具發展一片生機。
Driven by the application demand of high-tech and pillar industries, China's plastic moulds have formed a huge industrial chain, from upstream raw and auxiliary materials industry and processing, testing equipment to downstream machinery, automobiles, motorcycles, household appliances, electronic communications, building materials and other major application industries. Plastic moulds have developed a piece. Vitality.
