The iron shell molding process analysis and die design
Abstract: This paper will take the iron shell mold design, injection mold related key problems and advantages. This product is the main parts of auxiliary, is to use the plastic molding, high surface quality requirement of appearance, appearance is not allowed to leave have obvious marks, the performance analysis of plastic material, iron appearance design and modeling, according to the basic shape and size of plastic parts, such as search, selection of injection molding method. To solve the mould structure design is reasonable, the exhaust is better, after molding as far as possible to achieve accuracy requirements, want to consider the deformation in the process of forming. Best molding method choice, mould design and theoretical analysis. According to the detailed dimension checking relevant dimensions of injection mold and injection molding machine, and for verification and calculation of process parameters. After a preliminary review to identify the problems and correct, and then draw die general assembly drawing, according to the assembly drawing work molding parts and all the required processing of parts figure, at the same time considering parts processing technology. Preparation of the machining of the mould parts manufacturability is, understand mould processing process, processing technology, learn to analysis to determine the gating system and parting surface, mold flow analysis, to determine the best gating system. Make full use of the book of theory in the design process, in strict accordance with the mold design steps, refer to related mould parameters and mechanical manual, for plastic parts manufacturability analysis, determine the parting surface design, molding parts, the determination of cavity quantity, gating system design, etc. Complete set of 2 d and 3 d mold part drawing and assembly drawing, complete specification。
Key words: Injection mold; Iron plate; Inclined top; Thimble.
