Title The Sand-casting Craft Design of an Enclosed-switcher’s Outer Body
Abstract
Based on analyzing physical-chemical properties, structural properties, technic requirements, manufacturing batch and producing conditions of material ZL101-T4, the article aims to confirm the casting technique planning, technic parameters, to design casting technique blueprints, set up technic cards, and to guarantee the quality of key parts by using the part's features.
The article confirms the structure and frames via analyzing the part's basic information, finds out the probable problems and confirms the material's forming and features, analyzes the part's casting technics and puts up measures to release/avoid possible problems of parts' structural/technic problems.
The article confirms the means of casting parts, chooses the proper modeling methods, puts up various parting plans and selects the most ideal parting surfaces. Also the article confirms the most proper pouring position and designs the pouring system based on selecting parting surfaces, and sets up the detailed casting technic plans.
The article chooses the proper mechanical parameters to design the casting's feeding system. By using the PRO/E software the article accurately models the model and pouring system, and finishes the crafting of casting technic blueprints and casting technic cards.
