【正文】 要 模具是工業(yè)生產(chǎn)用的重要的工藝裝備，在現(xiàn)代工業(yè)生產(chǎn)中， 60%～ 90%的工業(yè)產(chǎn)品需要使用模具，模具工業(yè)以成為工業(yè)發(fā)展的基礎(chǔ)，許多新產(chǎn)品的研制與開發(fā)很大程度上依賴于模具的生產(chǎn)，因此，研究和發(fā)展模具技術(shù)，提高模具水平，對促進(jìn)國民經(jīng)濟(jì)的發(fā)展有著特別重要的意義。 本論文主要論述了材料為 ABS 的小尺寸、一般精度的提帶連接扣注射模的設(shè)計(jì)方法。然后針對該方案進(jìn)行了重點(diǎn)論述，主要包括側(cè)抽芯的塑件及其注塑模的設(shè)計(jì)過程、注塑模主要零部件的設(shè)計(jì)要點(diǎn)等。最后論文針對提帶連接扣塑件的成型工藝方法以及其模具采用側(cè)抽芯生產(chǎn)的可行性進(jìn)行了論證。 Abstract I Abstract Mold is an important setup in modern industry .In manufacturing industry,60～ 90 percent of products utilize mold. Molding industry has been a essential factor of industry development. A number of new products’ developments considerably depend on mold making. Therefore, it is significant for national economy to research and improve mold technology. The dissertation introduces the design of injection plastic mold for the button linked belt. the mold made by ABS is small size and mon precision. Firstly, The dissertation mainly explains the designing process of the mold. Secondly, The dissertation analyses shaping craft and devises the shaping strategy. The mold adopts one mold and four cavities and side pull. The dissertation gives fully analysis to the making process. Thirdly, the dissertation focuses on the analysis of the design of injection plastic molds for the button linked belt , including: side pull design。 decision of parting plane。 design of gating system。 strength verification, etc. Lastly, the dissertation demonstrates the feasibility of the design. KeyWords： the button linked belt injection plastic mold side pull Parted plane injection machine 目 錄 I 目 錄 摘 要 ........................................................................................................................
