1. Gate mould: gate mold is the gate and runner on the parting line, cavity together with the product release, design the most simple, easy processing, low cost, so a lot of people using gate mold. The plastic mold structure is divided into two parts: dynamic and definite. As the activity part of the injection molding machine is the moving mode (mostly the ejection side), the injection end of the injection molding machine is usually called the fixed mode. Because the mold part of the large water mouth is generally composed of two steel plates, it is also known as "two plates". The simplest structure in a large water mouth mold is two plates.
2. Fine runner mould, the runner and gate is not in the parting line, generally directly on the product, so to design a set of shuikou parting line, design is relatively complex, processing more difficult, often depending on the product requirements to choose fine runner system. The mould part of the thin nozzle is generally composed of three pieces of steel plate, which is also called the "three plate mold". The three - plate mold is the simplest structure in the thin - water mouth mold.
3. The mould of hot flow path: this kind of mold is approximately the same structure and fine shuikou, the biggest difference is that the flow is in one or more have temperature and heat flow but heat pumping mouth, no cold feeding demoulding, runner and gate directly on the product, so the port don't need mold release, also known as no runner system, this system can save raw materials, applicable to the raw material is more expensive, high requirement of products, design and processing difficulties, mould cost is high. Hot runner system mainly consists of hot sprue jacket, hot runner plate and temperature control box. Our common hot runner system has single point hot gate and multi-point hot runner. The single point hot gate is a single hot runner, which is used to insert the molten plastic into the cavity directly. The multi-point hot gate is used to separate the melt material from the hot runner to the heat gate sleeve and then into the cavity. It is suitable for single cavity multi-point feeding or multi-cavity mold.
