摘要

本設計課題是洗發水瓶蓋注塑模具的輔助設計與制造，分為注塑模具三維設計和二維裝配圖及零件圖三部分。塑料瓶蓋的材料選用聚丙烯。首先用Pro/e進行洗發水瓶蓋的三維造型，利用CAD/CAE作出輔助分析，通過查閱各種資料，完成包括形狀及尺寸方面的數據運算，然后根據洗發水瓶蓋的結構特點設計了模具的型芯、型腔、脫模及整體結構。此模具的結構較為復雜，動模和定模都采用了鑲拼結構。由于生產批量較大，采用一模兩腔、對排的布置方式。由于聚丙烯對熱較敏感，且此塑件的壁厚較薄，經過計算此設計可以不必加設冷卻水道。此外，為了縮短模具的生產周期，提高生產率，本設計在很多地方采用標準件，例如模架，導柱導套。在此基礎上，應用CAD軟件畫出整個注塑模具的裝配圖以及零件圖，并標注完全。最后完成整套模具的設計，可以對實際生產起到指導作用。

關鍵詞：洗發水瓶蓋；注塑模；聚丙烯；型芯；型腔

ABSTRACT

This issue is the assisted design and manufacturing of the injection mold of cap of shampoo bottle, which is including three-dimensional design of injection mold and two-dimensional map of assembly and parts drawings. Shampoo bottle is made of polypropylene. First Pro/E is used to form three-dimensional shape of the cap of shampoo bottle, CAD/CAE makes an assisted analysis. After reading a variety of available information, the data computation of the shape and size could be completed. And then the cap of shampoo bottle in accordance with the structural characteristics of the design of the mold the core, cavity, and the overall structure of molding. The structure of this mold is rather complex, the dynamic and determined mold are both adopted composite structure. Due to the larger quantities of production, A two-mode cavity is used, the arrangement of row. As the polypropylene is more sensitive to heat, and the thinner wall thickness of plastic parts, in this design can be calculated do not need additional cooling water. In addition, in order to shorten the production cycle of mold, and improve productivity, the design adopts standard in many places , such as mold, lead guide sets of columns. Based on that, the application of CAD software to draw the entire injection mold assembly, as well as parts of the map, and marked completely. Finally, a complete set of mold is designed, which can play a guiding role in the actual production.

Keywords: Cap of Shampoo Bottle；Injection Mold；Polypropylene；Core；Cavity
