根据浇注系统型制的不同可将塑料模具分为三类
（1）大水口模具：流道及浇口在分模线上，与产品在开模时一起脱模，设计最简单，容易加工，成本较低，所以较多人采用大水口系统作业。塑料模具结构分为两部分：动模和定模。随注射机活动部分为动模（多为顶出侧），在注射机射出端一般不活动称为定模。因大水口模具的定模部分一般由两块钢板组成故也有称此类结构模具为两板模。两板模是大水口模具中最简单的结构。(1) Large nozzle die: Runner and gate are demoulded together with the product on the parting line. The design is the simplest, easy to process, and the cost is low. Therefore, more people use large nozzle system to operate. The structure of plastic mould is divided into two parts: dynamic mould and fixed mould. The movable part of the injection machine is the movable part (mostly the ejection side), and the inactivity at the ejection end of the injection machine is generally called the fixed part. Because the fixed part of the large nozzle die is usually composed of two steel plates, it is also called the two-plate die. The two-plate die is the simplest structure of the large nozzle die. （2） 细水口模具：流道及浇口不在分模钢制闸门 钢坝 保定轻钢别墅 保定平面设计培训 保定室内设计培训 保定办公家具 保定空调维修 线上，一般直接在产品上，所以要设计多一组水口分模线，设计较为复杂，加工较困难，一般要视产品要求而选用细水口统。细水口模具的定模部分一般由三块钢板组成故也有称此类结构模具为“三板模”。三板模是细水口模具中最简单的结构。 (2) Fine nozzle die: the runner and gate are not on the parting line, generally directly on the product, so it is more complex to design a set of nozzle parting line, and difficult to process. Fine nozzle system is generally selected according to the product requirements. The fixed part of the fine nozzle die is generally composed of three steel plates, so it is also called "three plate die" for this kind of structural die. The three-plate die is the simplest structure of the fine nozzle die. |
