Description

Description of the injection molding process: The mold is a tool for producing plastic products. It consists of several sets of parts with a molded cavity. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and is cooled and shaped in the cavity, and then the upper and lower molds are separated, and the product is ejected from the cavity from the cavity through the ejection system, and finally the mold is closed. For the next injection, the entire injection molding process is cyclic.

(1) The mold line is demolded together with the product at the time of mold opening. The design is the simplest, easy to process, and the cost is low, so many people use the large nozzle system. (2) Sluice nozzle: The runner and gate 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 and the processing is more difficult. Generally, it depends on the product requirements. Sluice system. (3) Hot runner mold: This type of mold structure is basically the same as the fine water nozzle. The biggest difference is that the flow channel is in one or more constant temperature hot runner plates and hot nozzles, no cold material release, flow channel and pouring. The mouth is directly on the product, so the flow channel does not need to be demoulded. This system is also called the waterless mouth 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.
