Injection molding is to make glutinous fusibility form required plastic product with designed shape and size in closed molds under needed pressure by means of plastic extrusion and plasticity. The plastic product is a outer covering for a box body. According to its technical request and used request, ABS is to be closed as its material. According to its designed shape and the numbers of the products, we choose the SZ60 cast shaper. At the same time, we use the mold spot runner as the request of the beautiful of the surface and the quality of the products .This mold uses a mold cavity, two minute leaves ,make the congels the material out of the mold ,then,push the products out of the mold . The core and the cavity uses the cooling water system, tuck to exhaust the gas, but avoids the flaw. After ascertaining the project of the structure of the mould, protract mouldfitting drawing. At last, carry out an allaround checkout and auditing and launch into manufacture.Key words: the injection moulds, the outer covering for a box body, core , a mold cavity.目 錄摘要 .............................................................................................................................................IABSTRACT...............................................................................................................................II第一章 引言 .......................................................................................................................... 1 課題的背景 和意義 ................................................................................................ 1 注塑模具的現(xiàn)狀和發(fā)展 ........................................................................................ 1 本課題的研究對(duì)象、目標(biāo)和方法 ............................................................................3第二章 設(shè)計(jì)及計(jì)算過程...........................................................................................................5 確定零件加工的整體方案 ........................................................................................5 注塑工藝參數(shù)的校核 ................................................................................................7第三章 澆注系統(tǒng)與排氣系統(tǒng)設(shè)計(jì)...........................................................................................9 澆注系統(tǒng)的設(shè)計(jì)原則 ................................................................................................9 主澆道設(shè)計(jì) ..............................................................................................................10 澆口的設(shè)計(jì) ..............................................................................................................11 冷料穴和拉料桿的設(shè)計(jì) ..........................................................................................12 排氣系統(tǒng)的設(shè)計(jì) ......................................................................................................13第四章 成型零件設(shè)計(jì).............................................................................................................14 分型面的選擇 ..........................................................................................................14 成型零件的結(jié)構(gòu)與設(shè)計(jì) ..........................................................................................14 成型零件尺寸的計(jì)算 ..............................................................................................15第五章 導(dǎo)向與脫模機(jī)構(gòu)設(shè)計(jì).................................................................................................18 導(dǎo)向機(jī)構(gòu)設(shè)計(jì) ..........................................................................................................18 脫模機(jī)構(gòu)設(shè)計(jì) ..........................................................................................................
