液壓管路三通管接頭的注塑模具設(shè)計【側(cè)抽芯一模兩腔】

摘  要

　　塑料注射模具是成型塑料的一種重要工藝裝備，通過對液壓管路三通塑料模具設(shè)計,能夠全面的了解塑料模具設(shè)計的基本原則、方法.并能較為熟練的使用Proe4.0、AUTOCAD軟件進(jìn)行塑料模具設(shè)計,提高自己的繪圖能力。為今后從事設(shè)計工作打下了堅實(shí)的基礎(chǔ)。

　　隨著現(xiàn)代工業(yè)發(fā)展的需要，塑料制品在工業(yè)、農(nóng)業(yè)、日常生活和軍事等各個領(lǐng)域的應(yīng)用范圍越來越廣，質(zhì)量要求也越來越高，中國已經(jīng)成為全球最大的塑料市場之一，塑料制品產(chǎn)量全球第二。為了做到高質(zhì)、高效、低成本，從而提高市場占有率，注塑模具的開發(fā)、設(shè)計、加工與CAD/CAE/CAM技術(shù)相結(jié)合具有重大意義。

本次主要設(shè)計是對液壓管路三通注射模的設(shè)計, 重點(diǎn)對塑件的成型原理、原料選用和注射技術(shù)進(jìn)行分析。通過根據(jù)形狀、尺寸、精度及表面質(zhì)量要求的分析結(jié)果，確定所需的模塑成型方案，制品的后加工、分型面的選擇、型腔的數(shù)目和排列、成型零件的結(jié)構(gòu)、澆注系統(tǒng)等。

關(guān)鍵詞：注塑模；模具結(jié)構(gòu)；側(cè)型芯；工藝方案

Abstract

Plastic injection mold is an important technological equipment of plastic forming, based on the hydraulic piping tee plastic mold design, can fully understand the basic principles, methods of plastic mold design. And can be used more skilled Proe4.0, AUTOCAD software for plastic mold design, improve their ability to draw. Engaged in the design for the future work laid a solid foundation.

With the needs of the development of modern industry, plastic products in industry, agriculture, military and other fields of daily life and the application scope is more and more wide, the quality requirements also more and more high, China has become one of the world's largest plastics market, plastic products production in the world's second. In order to achieve high quality, high efficiency, low cost, and improve the market share, injection mold development, design, processing combined with CAD/CAE/CAM technology is of great significance.

The main design is the design of injection mold hydraulic piping tee, focus on the forming principle of plastic parts, raw materials selection and injection technology were analyzed. By according to the shape, size, precision and surface quality requirement analysis, to determine the required molding solutions, products after processing, the choice of the parting surface, cavity number and arrangement, the structure of molding parts, pouring system, etc.

Key words: injection mold; The mold structure; The side core; The processing plan
