The design is based on injection molding, thermoplastic injection molding process is forming the main way to do this is to Add Barrel plastic raw materials in the melt after heating to a high viscosity of the fluid, the plunger or screw used as a pressure tool so that the higher the melt through the nozzle into the mold cavity pressure in, after cooling, solidification stage, and then emerge from the mold and bee plastic. During the design process, the first box on the plastic boxes are plastic parts for process analysis, to understand the characteristics of this type of plastic, uses, etc.。 此次設(shè)計(jì)不僅使我對(duì)書本有了進(jìn)一步的了解，而且讓我了解到許多書本上沒有的東西，更讓我讓我所學(xué)到的理論與實(shí)際結(jié)合起來(lái)，這為我以后的工作鋪下了重要 基礎(chǔ)，從而讓我在此次設(shè)計(jì)中收益很多。材料為 10，厚度 t=。本套模具的設(shè)計(jì)不是以復(fù)雜模具的設(shè)計(jì)為主，而主要是對(duì)模具設(shè)計(jì)知識(shí)的系統(tǒng)學(xué)習(xí)和設(shè)計(jì)的練習(xí)，以達(dá)到掌握知識(shí)和設(shè)計(jì)方法的目的。在設(shè)計(jì)過程中，首先對(duì)塑料飯盒盒身塑件進(jìn)行工藝分析，了解此類型塑料的特性、用途等；在對(duì)模具的結(jié)構(gòu)進(jìn)行分析，根據(jù)模具的基本結(jié)構(gòu)來(lái)進(jìn)行對(duì)模架的選取，然后再對(duì)各種相關(guān)的工藝參數(shù)進(jìn)行校核，以及根據(jù)書上的和圖書館叢書的公式和一系列表、參數(shù)等進(jìn)行對(duì)型腔和型芯等的計(jì)算，最后進(jìn)行模具的加熱、試模等主要內(nèi)容。塑料飯盒盒身具有重量輕、易清潔、耐腐蝕老化、強(qiáng)度高、使用壽命長(zhǎng)，制作方便、價(jià)格低廉等特點(diǎn)，是值得人們信賴、喜歡用的產(chǎn)品，它具有非常大的發(fā)展前途。 本次設(shè)計(jì)的是“飯盒注塑?！焙汀叭龎|片套排復(fù)合沖裁模”。 1 摘要 在工業(yè)生產(chǎn)高度發(fā)展的現(xiàn)代社會(huì)里，利用模具加工是一種重要的加工方法，在一些國(guó)家里模具甚至被稱為是 “ 黃金 ” 、 “ 金屬加工業(yè)中的帝王 ” 、 “ 磁力工業(yè) ” 等。這些都足以看出模具在工業(yè)中的重要地位。 （ 1）飯盒注塑模主要介紹了塑料飯盒盒身的設(shè)計(jì)思路和加工過程。本設(shè)計(jì)采用的是注射成形，注射成形是成形熱塑加工的主要方法，就是 把塑料原料放入料筒中經(jīng)過加熱熔化，使之成為高黏度的流體，用柱塞或螺桿作為加壓工具，使熔體通過噴嘴以較高壓力注入模具的型腔中，經(jīng)過冷卻、凝固階段，而后從模具中脫出，成為塑料制品。 （ 2）三墊片套排復(fù)合沖裁模是針對(duì)復(fù)合沖裁模具 的設(shè)計(jì)，在第二章中，先是對(duì)沖裁件的結(jié)構(gòu)工藝性進(jìn)行分析，然后依次確定模具的類型、總體結(jié)構(gòu)，最后是沖裁力和主要的尺寸計(jì)算、標(biāo)準(zhǔn)件的選用、零件圖和裝配圖的繪制。這一套模具是三個(gè)墊片的沖裁模，結(jié)構(gòu)緊湊簡(jiǎn)單。加工工序?yàn)槁淞稀_孔。 關(guān)鍵詞： 注射成形 ； 型腔 ； 型芯 ； 落料 ；沖孔 2 Abstract Industrial production in the highly developed modern society, the use of mold processing is an important processing methods, in some countries and even mold has been called the gold, Metal processing industry of the emperor, magic industry and so on. These are sufficient to see die in an important position in the industry. The design is the injection mold boxes and the three sets of row posite gasket Die. (1) introduces the injection mold boxes plastic boxes are the design of box thinking and processing. Plastic boxes with boxes are light weight, easy to clean, corrosionresistant aging, high strength, long service life, the production of convenience, low prices and so on, is worthy of people39。 in the analysis of the structure of mold, according to the basic structure of molds for the selection of the mold, and then of various process parameters related to verification, as well as books and library books on the formula and a series of tables, parameters such as cavity and core of the calculation, etc., and finally heating the mold, such as the main contents of test mode . (2) three sets of row posite gasket Die Blanking Dies for posite design, in the second chapter, the first pieces of the structure of the blanking process of analysis, to be followed to determine the type of mold, the overall structure, and finally blanking force and the size of the main terms of the selection of standard parts, spare parts and assembly diagram mapping. This is not a set of mold design mold design to the main plex, and the main knowledge of mold design and design of a systematic study of the practice, to acquire knowledge in order to achieve the purpose and design methods. This set of three pads of die Die, simple and pact structure. Material 10, thickness t = . Processes 3 for blanking, punching. The design not only makes me have a better understanding of the books, but I did not understand many things in books, but also I learned so I bine the theory and practice, which I will work for a Shop an important foundation, so I have a lot of the design proceeds. Key words: injection molding； cavity。 1 1 、七十年代（空白階段） 1 （競(jìng)爭(zhēng)階段） 3 3 5 5 6 、卸料力及推件力的計(jì)算 7 9 9 12 12 17 20 20 21 22 22 23 24 26 28 28 29 30 31 33 33 33 參考文獻(xiàn) 35 謝辭 41 7 第 1 章 綜述 概述 工、模具材料是工模具加工業(yè)的基礎(chǔ)。中國(guó)的模具材料從無(wú)到有，從小到大，從少到多， 直到現(xiàn)在，無(wú)論是從鋼種還是從規(guī)格、標(biāo)準(zhǔn)化、系列化等方面，都是伴隨著模具制造發(fā)展而發(fā)展的。再則由于工業(yè)發(fā)展的緩慢和經(jīng)濟(jì)封閉，以及人民的生活水平處于很低的消費(fèi)水平等諸多因素，抑制了模具制造的產(chǎn)業(yè)化、社會(huì)化和商品化。 八 十年代（發(fā)展階段） 隨著改革開放和國(guó)民經(jīng)濟(jì)的增長(zhǎng)，很大程度上推動(dòng)了模具制造業(yè)的發(fā)展。不僅改善了加工性能，而且還大大提高了模具的使用壽命。據(jù) 1997 年統(tǒng)計(jì)，我國(guó)年耗模具材料 13 萬(wàn)噸，其中普鋼 噸。而作為一個(gè)工業(yè)日趨發(fā)展，產(chǎn)品交替更新節(jié)奏很快的國(guó)家，其對(duì)模具的發(fā)展也更進(jìn)一步地被產(chǎn)品生產(chǎn)商重視。但是，模具材料由于其規(guī)格繁多，同規(guī)格單次需求量少，市場(chǎng)即時(shí)采購(gòu)等特點(diǎn)，使得各大鋼廠規(guī)模性生產(chǎn)裝備無(wú)法適應(yīng)?？墒牵姸嗟拇砩屉m然手中握有厚資，但是對(duì)于模具工況 條件，材料特性以及相關(guān)熱處理等問題的了解不夠，都停留于普鋼類方面的激列競(jìng)爭(zhēng)。如：瑞典的 NUDDEHOLM、 ASSAB，以及德國(guó)的蒂森、薩斯特，日本的大同等公司都在上海乃至全國(guó)各地樹起了優(yōu)特鋼的旗幟，但由于他們的價(jià)格過高，已逐漸顯得
