The injection mold design of Relay box
Abstract: Mold industry development increases people's attention and concern. "Die industrial production base technology and equipment" has also been achieved consensus. In electronics, automotive, electrical, electronics, instruments, meters, home appliances and other communications products, 60% to 80% of the parts must rely on molding. Mold design process described in this report, the various institutions and systems were analyzed, in addition to injection mold design introduced relay box, including: how to determine the core, the size of the cavity, and the cavity to determine the number, cavity arrangement, sub-surface selection, side parting pulling mechanism design, gate design, launch and reset mechanism manner determined; volume and quality of the plastic parts of the calculation, plastic injection process analysis and machine parameters OK; mold heating and cooling systems computing; how to determine the height of the mold is closed. Design process using AutoCAD, UG and other computer-aided software to draw a diagram of the major components, products, maps, and a large structure design, greatly reducing the design cycle.
Key words: Relay box; Injection molding ; Plastic molding
