【正文】 1 摘要 在工業(yè)生產(chǎn)高度發(fā)展的現(xiàn)代社會里，利用模具加工是一種重要的加工方法，在一些國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。 本次設計的是“飯盒注塑?！焙汀叭龎|片套排復合沖裁模”。 （ 1）飯盒注塑模主要介紹了塑料飯盒盒身的設計思路和加工過程。塑料飯盒盒身具有重量輕、易清潔、耐腐蝕老化、強度高、使用壽命長，制作方便、價格低廉等特點，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。本設計采用的是注射成形，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。在設計過程中，首先對塑料飯盒盒身塑件進行工藝分析，了解此類型塑料的特性、用途等；在對模具的結(jié)構(gòu)進行分析，根據(jù)模具的基本結(jié)構(gòu)來進行對模架的選取，然后再對各種相關的工藝參數(shù)進行校核，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)等進行對型腔和型芯等的計算，最后進行模具的加熱、試模等主要內(nèi)容。 （ 2）三墊片套排復合沖裁模是針對復合沖裁模具 的設計，在第二章中，先是對沖裁件的結(jié)構(gòu)工藝性進行分析，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算、標準件的選用、零件圖和裝配圖的繪制。本套模具的設計不是以復雜模具的設計為主，而主要是對模具設計知識的系統(tǒng)學習和設計的練習，以達到掌握知識和設計方法的目的。這一套模具是三個墊片的沖裁模，結(jié)構(gòu)緊湊簡單。材料為 10，厚度 t=。加工工序為落料、沖孔。 此次設計不僅使我對書本有了進一步的了解，而且讓我了解到許多書本上沒有的東西，更讓我讓我所學到的理論與實際結(jié)合起來，這為我以后的工作鋪下了重要 基礎，從而讓我在此次設計中收益很多。 關鍵詞： 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。s trust and like to use the products, it has a very big development prospects. 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.。 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。core； blanking； punching. 4 目錄 第 1章 綜述 1 1 1 、七十年代（空白階段） 1 （發(fā)展階段） 1 （競爭階段） 1 第 2章 三墊片套排復合沖裁模設計 3 3 3 3 3 4 4 5 5 5 5 6 、卸料力及推件力的計算 1
