Abstract:

In this work，we designed a bicolor injection mold for the cover of an intelligent positioner according to its structural characteristics and test requirements. The mold structure was simplified， and the safety and stability of the mold ope⁃ration were improved by using a fixed mold side core⁃pulling mechanism. The auxiliary flow channel of ABS melt was formed by employing a process core. As a result， the melt could enter the cavity from the inner side through the submarine gate. This ensured the appearance quality of the molded products and realized the automatic bicolor molding. As the mold was put into production， the operation of the mold was confirmed to be safe and stable， and the quality of the molded products reached the design requirements. All of these indicated that the mold structure was advanced and reasonable.

Key words: intelligent positioner cover, bicolor injection mould, submarine gate, process core, fixed mold side core pulling mechanism
