The Folder Cousy V-shaped Body Mould Design Process
Abstract:This design specifications briefly explain the Folder Cousy V-shaped body mould design process. First from should model the material which an institute selects UPVC, models the precision request, the production batch and so on several angles carries on the analysis, the definite mold takes shape the plan. The concrete content including the casting machine choice, the cavity number determination, models the platoon position, pides the determination, the mold intensity, takes shape the components design, the commonly used structural element design, the good position design, the drawing of patterns organization, pours the system, the mold temperature and the cooling system design and so on, and to some commonly used standard letters which selected in the design has carried on the explanation. Type core calculation must take into account the products has an average shrinkage, but also on some special parts size to carry the required process analysis and verification.
Keywords: UPVC; come off the mechanism of model; cooling system ;gating system; mold design; injection mold
