Abstract

To provide a molding method capable of effectively preventing the occurrence of the deformation failure of a molded product at the time of mold release by providing a simple pressure mechanism to a mold even in a case of a complicated molded product provided with a narrow region and capable of sharply improving the production yield and productivity of the molded product, and a molding machine.

Description

technical field [0001] The present invention relates to a molding method, and in particular to a molding method which can effectively prevent the Deformation defects occur in molded parts, whereby the manufacturing output and productivity of molded parts can be significantly increased. Background technique [0002] In recent years, due to advances in the field of information technology, the functionality of personal computers and other electronic devices has been increasing, while the size of these devices has become increasingly smaller. Accordingly, there is a continuing need for increasingly complex and smaller enclosures to accommodate the precise constituent and functional components of these electronic devices. These casings (used here to cover all the concepts of "casing", "casing", etc.) are integrally formed therein with many ribs for increasing its strength, and for storing constituent parts such as battery packs, hard disk drives (HDDs, etc.) ), expansion memory...
