摘 要
伴隨著全球性經(jīng)濟發(fā)展，新技術革命浪潮不斷的突破與發(fā)展，跨越性的技術發(fā)展已經(jīng)成為推動世界經(jīng)濟增長的重要因素。市場經(jīng)濟的不斷繁榮，極大地促進了對體積小，工業(yè)產品的品種多，低成本，高品質的方向發(fā)展。為了提高生產周期的市場競爭力的核心產品的要求越來越高，開發(fā)周期短，因此對各種產品的制造的關鍵技術及設備，模具的要求也越來越嚴格和苛刻的。
模具是基礎工業(yè)之一。隨著市場經(jīng)濟全球化趨勢和各種高新技術的迅猛發(fā)展，快速經(jīng)濟模具被賦予了新的內涵和新的任務，種類的激增，促使快速經(jīng)濟制模材料向著多品種系列化邁進，不斷促使工藝有新突破和發(fā)展。鑒于商品經(jīng)濟的快速發(fā)展，產品換代更新的加速，以及市場競爭愈發(fā)激烈，都愈發(fā)高的刺激著快速經(jīng)濟制模技術朝著短周期、低成本、高質量及高制造精度等方向發(fā)展。鑒于它能夠使企業(yè)獲得更大的市場，創(chuàng)造更大顯著的經(jīng)濟效益，因此愈發(fā)受到企業(yè)家的垂青以及獲得相關領導部門的政策資金的支持。鑒于快速發(fā)展的高新技術以及各種技術的綜合運用，未來必定會產生新型節(jié)能省材的快速制模技術來適應社會生產中差異化需求。
此次畢業(yè)設計是對塑料斜齒輪注塑模具設計，難點在于實現(xiàn)自動旋轉脫螺紋功能。本設計有兩大亮點，一是使用齒輪齒條傳動機構來實現(xiàn)測抽芯，二是用軸承使型腔旋轉來實現(xiàn)脫螺紋設計。因模具中有多處需要配合，可能使模具在制造和裝配方面有些難度。

Abstract
With the global economic development, new technology revolution continued breakthroughs and development, leapfrog technology development has become an important factor in promoting world economic growth . Continued prosperity of the market economy , which greatly promoted to small, multi- variety of industrial products , low-cost , high-quality direction. In order to enhance the core products in the market competitiveness of the production cycle, and increasingly demanding shorter development cycle , and therefore the key to the manufacture of various products, technology and equipment - mold requirements are increasingly stringent and demanding .
Mold is one of the basic industries . With the rapid development of economic globalization and a variety of high-tech markets , rapid economic mold was given a new meaning and a new task , the type of surge , prompting rapid economic modeling material moving toward multi- variety series , continue to promote technology breakthroughs and development. Given the rapid development of the commodity economy , accelerate the upgrading products , and market more competitive , are increasingly high to stimulate rapid economic modeling techniques towards short-cycle , low-cost , high-quality and high manufacturing precision direction. Given its ability to enable enterprises to gain a larger market , creating greater significant economic benefits , and therefore increasingly favored by the entrepreneurs and access to funding to support policies related to the leadership department. Given the rapid development of high-tech and comprehensive use of various technologies , the future will certainly generate new energy-saving materials for rapid tooling technology to meet the social needs of the difference in production .
??The graduation project is a plastic injection mold design helical gear , the difficulty lies off the automatic rotation of the threaded function. This design has two bright spots , one using rack and pinion mechanism to achieve measured Pulling , two bearings so that the cavity is rotated to achieve the de- thread design . Because there are many die with blood , may cause some difficulty in mold manufacturing and assembly areas .
