How to classify pouring system type mold

Molds can be divided into three categories according to the type of gating system.

1. Dashuikou

The mold crossing line is released together with the product when the mold is opened. The design is the simplest, easy to process, and the cost is low, so more people use the large water outlet system for operation.

2. The mold channel and gate of the fine nozzle are not on the parting line, but are generally directly on the product. Therefore, an additional group of nozzle parting lines should be designed. The design is more complicated and the processing is more difficult. Generally, the fine nozzle system should be selected according to the product requirements. .

3. Hot runner mold The structure of this type of mold is basically the same as that of the fine nozzle. The biggest difference is that the runner is in one or more hot runner plates and hot nozzles with constant temperature. There is no cold material demoulding, and the runner and gate are directly In terms of products, the runner does not need to be demolded. This system is also called the no-spout system, which can save raw materials. It is suitable for situations where raw materials are expensive and product requirements are high. Design and processing are difficult, and mold costs are high.
