The hanger mold is an important factor in the hanger shape and quality. The hanger mold in the mold classification is almost all classified as the injection mold classification, mainly related to the processing and use of the mold. Specifically, the heat-melted material is injected into the hanger mold chamber at high temperature, and after cooling and curing, to get the hanger forming product.The injection molding process of Leo mold coat hanger can be roughly divided into the following six stages, “mold-injection-pressure preservation-cooling-open mold-plastic coat hanger out”, the above process is repeated, can be continuous production of products. The hanger mold can be made into multi-chamber mold, a mold can be out of multiple hanger products. In the process of mold processing, the production of one two and one four hanger mold.
The material selection of hanger mold mainly considers the thermal strength, thermal stability of steel and the hardness of steel itself. Commonused mold materials:
45 # steel: No.45 steel is carbon structure steel, hardness is not high easy to cut, the corresponding processing cost is lower than other steel. The general output is not very high, production requirements, coat hanger quality requirements are not very high suggestions to choose.
P20: pre-hard plastic die steel. Suitable for the long-term production of high-quality plastic molds. This steel has good cutting and can be generally polished 718:718 mold steel use is the same as P20 type mold steel, but due to better quenching ability, better performance, can make large size, good plastic mold forming parts.
H13: H13 steel is hot mold steel. Before processing, the vacuum quenching hardness is more than 50
