According to casting system type system can be divided into three types of mold: (1) Dashuizu die: runner and gate in the parting line, and the product together in the mold when the mold release, the design is the simplest, easy processing, lower cost, so more people use the large nozzle system operation. (2) Watertight die: the runner and gate are not parting line, generally directly on the product, so to design more than a set of outlet die line, the design is more complex, processing more difficult, generally depending on the product requirements and selection Watertight system. (3) hot runner mold: the structure of such molds and the nozzle roughly the same, the biggest difference is that the runner is in one or more of the thermostat hot runner plate and heat pump mouth, no cold mold stripping, runner and pouring The port is directly on the product, so the runner does not need to be demolded. This system is also called a portless system, which can save raw materials, is suitable for the situation that the raw materials are expensive and the products require higher design and processing difficulties, and the mold cost is higher.
