Abstract
The present invention relates to an injection molding apparatus having a separation type mold and a controlling method thereof, and more particularly, to an injection molding apparatus having a separation type mold, which includes a separate intermediate mold formed with a cavity or core surface that can be heated before injection molding and be cooled simultaneously with the injection molding such that the injection molding can be completed for a short cycle time, and a controlling method thereof. The injection molding apparatus of the present invention comprises a cavity mold formed with a cavity surface for defining a cavity in which a molten injection material is injected, a core mold formed with a core surface for defining the cavity upon engagement with the cavity mold and installed to be movable forward and backward to open or close the cavity by guidance of a guide pin, an injection unit for injecting a material into the cavity during an injection process, and an injection controller for controlling a hydraulic cylinder to move the core mold forward or backward and the injection unit to inject the material into the cavity.
Description
technical field [0001] The present invention relates to an injection molding device with a separate mold and a control method thereof, more specifically, to an injection molding device with a separate mold and a control method thereof. A separate intermediate mold can be heated before injection molding and cooled at the same time as injection molding, so that injection molding can be completed in a short cycle. In addition, the present invention relates to an injection molding apparatus having a separate type mold and a control method thereof, in which high-quality injection molded products are manufactured by maintaining desired temperatures of various regions on the mold face during injection molding . Background technique [0002] Injection molding of synthetic resin or metal refers to injecting molten synthetic resin or metal between a static mold (cavity mold) with a cavity and a moving mold (core mold) with a core, and then injecting synthetic resin The resin or meta...
