（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：流道及浇口不流水槽钢模具 不锈钢铸件 扭王字块模具 井盖钢模具 标志桩模具 调匝式消弧线圈 风冷控制柜 烤漆龙骨在分模线上，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 group 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.
（3） 热流道模具：此类模具结构与细水口大体相同，其最大区别是流道处于一个或多个有恒温的热流道板及热唧嘴里，无冷料脱模，流道及浇口直接在产品上，所以流道不需要脱模，此系统又称为无水口系统，可节省原材料，适用于原材料较贵、制品要求较高的情况，设计及加工困难，模具成本高。 热流道系统，又称热浇道系统，主要由热浇口套，热浇道板，温控电箱构成。我们常见的热流道系统有单点热浇口和多点热浇口二种形式。单点热浇口是用单一热浇口套直接把熔融塑料射入型腔，它适用单一腔单一浇口的塑料模具；多点热浇口是通过热浇道板把熔融料分枝到各分热浇口套中再进入到型腔，它适用于单腔多点入料或多腔模具。
(3) Hot runner die: The structure of this kind of die is basically the same as that of fine nozzle. The biggest difference is that the runner is located in one or more hot runner plates and hot suckers with constant temperature. There is no cold material demoulding. The runner and gate are directly on the product. Therefore, the runner does not need demoulding. This system is also called no nozzle system, which can save raw materials and is suitable for more expensive raw materials and products with higher lizhu.37ix.com.cnshujun.37ix.com.cnfuheguann.37ix.com.cnwufangbus.07858.net tiexin.07858.net youxiang.07858.netrequirements. It is difficult to design and process, and the cost of die is high. Hot runner system, also known as hot runner system, mainly consists of hot runner sleeve, hot runner plate and temperature control electric box. Our common hot runner system has two forms: single point hot runner and multi point hot runner. Single point hot gate is to inject molten plastic directly into the cavity by a single hot gate sleeve, which is suitable for single cavity and single gate plastic mould; multi point hot gate is to divide the molten material into each branch Heat Gate sleeve by a hot gate plate and then enter into the cavity. It is suitable for single cavity and multi point feed or multi-cavity mould
