堵頭注塑模具設計【一模四腔含26張CAD圖紙及proe三維】
摘 要
從19世紀開始,塑料就開始發(fā)展了起來,從合成樹脂到現(xiàn)在各種各樣的化合物,可謂是日益完善,而模具也是從這時候發(fā)展起來的。塑料模具的分類很多,按照塑料制件的不同可分為:注射模、壓縮模、壓注模、擠出模、氣動成型模等。注塑模具又稱注塑成型,是熱塑性塑料制品生產的一種重要的方法。除少數(shù)塑料制品外,幾乎所有的熱塑性塑料都可以用注射成型方法生產塑料制品?,F(xiàn)如今模具已經成為了發(fā)展中不可或缺的產物,對未來的發(fā)展也有這重大的貢獻。
本文主要介紹堵頭注塑模具的設計方法。首先通過對堵頭工藝特點,包括材料性能、結構工藝和成型特性等進行分析而進行設計。在設計該模具的同時,學習模具知識和設計方法,通過旋轉脫螺紋機構的設計,融匯了課程中的基礎知識到其中。同時引用了CAD、Pro/E等技術,建立修改二維三維圖紙。而在應用軟件的同時,也發(fā)現(xiàn)自己的不足并改進,從而提高自己對零件的了解和軟件的熟練操作,從而達到設計目的。

ABSTRACT
From the 19th century, the plastic began to develop, from synthetic resin to now a variety of compounds, can be described as increasingly perfect, and the mold is also developed from this time. Plastic mold a lot of classification, according to the different plastic parts can be divided into: injection mold, compression mold, injection mold, extrusion die, pneumatic molding die. Injection molding mold, also known as injection molding, is an important method of production of thermoplastic products. In addition to a small number of plastic products, almost all of the thermoplastic can be used to produce plastic injection molding method. Now the mold has become an indispensable product of development, the future development also has this significant contribution.
This paper mainly introduces the design method of plug injection mold. First of all, through the plug process characteristics, including material properties, structural processes and molding characteristics of the analysis and design. In the design of the mold at the same time, learning mold knowledge and design methods, through the rotation off the screw body design, integration of the basic knowledge of the course to which. At the same time cited the CAD, Pro / E and other technologies, the establishment of modified two-dimensional three-dimensional drawings. And in the application software at the same time, also found their own deficiencies and improvements, so as to improve their understanding of the parts and software proficiency in operation, so as to achieve the purpose of the design.
