塑膠模具組裝公差分析之研究

隨著時代與工業的進步與轉變，產品的開發與生產的速度迅速，因應而生的模具製造也同時搭配生產速度以符合趨勢所需，塑膠產品的生產須靠塑膠模具置於塑膠射出機成型生產，模具的設計與加工影響後端組裝與塑膠射出成型生產息息相關為一連續性問題，而模具的製作無可避免的會受到人為和環境因素的影響，因而產生零件的尺寸無法製作於設計尺寸精密度內，而製造模具零件時必定有所誤差，設計者如何設計精準的加工精度搭配加工製程給予最佳的誤差值，使零件符合規格要求，這為公差分析。公差分析運用於產品設計、模具設計到生產製造均為重要分析運作，公差的定義影響到後端的加工方式與成本費用，在這競爭激烈的時代如何準確又快速的達成模具零件製造與組立，本論文主要以分析手法運用於模具公差分析並探討各二次加工製程上之影響與公差變化。研究利用設備精度、製程分析與統計模擬求出公差值區段。

With the progress and change of the industry era, the development and production become rapid. And then the process of mold production that fit to the trend is necessary to get faster. The production of plastic product depends on the mold deposed in the injection machine, mold design and finish influence the follow-up fabrication and product formation. Because the production of mold is inevitably influenced by environment and artificial cause, the size of production is not precisely fitted to the design. How the designer confers the error value to match precise fabrication of the production to make the part fit in with the dimension is called the analysis of tolerance. The analysis of tolerance used in the design of production the design of mold and the fabrication of production are important for follow-up mode of fabrication and cost of the production. To procure precision and rapidness of mold fabrication in the competitive era this thesis discusses the influence of second finish process to the tolerance of mold with analytical tool. This thesis use precision of the equipment, analysis of the process and simulation of the statistics to calculate range of tolerance.
