摘 要:注塑成型是批量生產(chǎn)某些形狀復(fù)雜部件時(shí)用到的一種加工方法。具體指將受熱融化的材料由高壓射入模腔，經(jīng)冷卻固化后，得到成形品。注射成型是熱塑性塑料成型的主要方法之一，可以一次成型形狀復(fù)雜的精密塑件。本次畢計(jì)業(yè)設(shè)計(jì)的題目是：電池后蓋的塑件注射模。本件與前盒配合，本次設(shè)計(jì)主要是通過對(duì)塑件的形狀、尺寸及其精度的要求來進(jìn)行注射成型工藝的可行性分析。塑件的成型工藝性主要包括塑件的壁厚，斜度和圓角以及是否有抽芯機(jī)構(gòu)。通過以上的分析來確定模具分型面、型腔數(shù)目、澆口形式、位置大?。黄渲凶钪匾氖谴_定型芯和型腔的結(jié)構(gòu)，例如是采用整體式還是鑲拼式，以及它們的定位和固緊方式。此外還分析了模具受力，脫模機(jī)構(gòu)的設(shè)計(jì)，合模導(dǎo)向機(jī)構(gòu)的設(shè)計(jì)，冷卻系統(tǒng)的設(shè)計(jì)等。最后繪制完整的模具裝配總圖和主要的模具零件圖等。 關(guān)鍵詞：分型面、澆口、型腔，型芯，脫摸力，潛伏澆口
ABSTRACT:Injection molding is a processing method used in the mass production of complex shape parts. Specific heat to melt the material by high-pressure injections mold cavity, cooled and solidified to obtain a molded article.thermoplastic injection molding plastic molding is the main method of forming the shape can be a complex precision plastic parts.this graduate design is: The mold of the behind cover plank of the remote controller .This design primarily passes to piece viability assessment for request for of shape, size and its accuracy coming proceeding injecting type craft .the piece the wall for of type craft primarily including the piece is thick, slope and circle angle and whether to have core-pulling or not mechanism. Pass the above analysis to come the certain molding tool cent the type the surface, type the number, gate the form, place the size; The among them and most important is a certain type core and the construction of the type , for example adopt the whole the type of type still , and their fixed position and tight way of .In addition and still analyzed the molding tool to suffer force, mold that design that the design of the pattern draw mechanism, match the design etc. to lead to the mechanism, cooling system. Finally, draw a complete mold assembly General Plan and the main mold parts diagram. Key words: parting line, the gate, cavity, core, mold insert, ejection force, submarine gate |
