The high-precision hot pressing grouting valve film mold of the large nozzle mold, the runner and the gate are on the parting line, and the product is demolded together when the mold is opened. The design is the simplest, easy to process, and the cost is low, so more people Work with a large nozzle system. The plastic mold structure is divided into two parts: dynamic mold and fixed mold. As the active part of the injection machine is a moving mold (mostly the ejection side), the inactive portion of the injection machine is generally called a fixed mold. Since the fixed mold part of the Dashui mold is generally composed of two steel plates, it is also called a two-plate mold. The two-plate mold is the simplest structure in a large nozzle mold.
The flow path and gate of the high-precision hot pressing grouting valve film mold are not on the parting line, generally directly on the product, so it is necessary to design a set of nozzle parting lines, the design is more complicated, the processing is more difficult, generally depends on the product. The sluice system is used as required. The fixed mold part of the fine nozzle mold is generally composed of three steel plates, so it is also called "three-plate mold". The three-plate mold is the simplest structure in a thin nozzle mold.
The high-precision hot pressing grouting valve membrane mold structure is basically the same as that of the fine water nozzle. The biggest difference is that the flow channel is in one or more constant-temperature hot runner plates and hot grouting nozzles, no cold material demoulding, runners and gates. Directly on the product, the flow channel does not need to be demoulded. This system is also called the waterless port system, which can save raw materials, is suitable for the case where the raw materials are expensive and the product requirements are high, the design and processing are difficult, and the mold cost is high.www.yxhgmould.com
