 摘  要

模具作為一種成型工具，其設(shè)計(jì)、制造水平的高低，直接關(guān)系到產(chǎn)品的質(zhì)量與更新?lián)Q代，是衡量一個(gè)國(guó)家產(chǎn)品制造水平的重要標(biāo)志。

支撐管彎頭體積較小、內(nèi)部結(jié)構(gòu)復(fù)雜，因而對(duì)注射成型模具和成型工藝的要求極高。支撐管彎頭注射模設(shè)計(jì)制造的最大難點(diǎn)在于成型部件、澆注系統(tǒng)、脫模機(jī)構(gòu)的設(shè)計(jì)。然后用Solidworks進(jìn)行三維實(shí)體建模,再進(jìn)行實(shí)體分析,確定出型腔數(shù)目,初選出成型設(shè)備,確定塑件的擺放位置,然后進(jìn)行分型面的確定,澆口的確定,確定結(jié)構(gòu)草圖,再搭配Solidworks的moldflow可以非常有效的進(jìn)行模架設(shè)計(jì),然后進(jìn)行抽芯機(jī)構(gòu),推出機(jī)構(gòu),復(fù)位機(jī)構(gòu)的設(shè)計(jì),冷卻系統(tǒng)的設(shè)計(jì),最后在Solidworks下進(jìn)行機(jī)構(gòu)模擬分析和校核。在這過(guò)程中經(jīng)常發(fā)現(xiàn)不合理或者干涉的情況,然后分析這些狀況產(chǎn)生的原因,然后進(jìn)行修改,直到最后確定比較合理的方案。方案出來(lái)以后,再利用Solidworks的有限元分析功能對(duì)模具的受力部分進(jìn)行強(qiáng)度校核,這也是Solidworks比較強(qiáng)大的功能之一。當(dāng)完全確定沒(méi)有問(wèn)題的時(shí)候,就進(jìn)行二維圖形的繪制。在繪制二維圖形的時(shí)候,運(yùn)用目前機(jī)械行業(yè)最有有效的二維圖紙繪制方法---由三維轉(zhuǎn)成二維。這不但在設(shè)計(jì)的過(guò)程思維更加清晰, 把大量經(jīng)歷用于機(jī)構(gòu)的優(yōu)化和完善,最重要的是大大提高的繪圖速度和準(zhǔn)確性,這在目前的經(jīng)濟(jì)時(shí)代是非常重要的。

這套模具最重要的是通過(guò)傳統(tǒng)和現(xiàn)代二種思維方法來(lái)設(shè)計(jì)的,可以親身體會(huì)出二種方法各自的優(yōu)缺點(diǎn),取長(zhǎng)補(bǔ)短?？梢宰寕鹘y(tǒng)工業(yè)煥發(fā)出新的活力,也提高了大家學(xué)習(xí)興趣。

Abstract

Die as a tool for molding, its design, manufacture level are of direct bearing on the quality of products and replacement, an important indicator to measure a country's level of manufacturing. 

   Support elbow is of small size and complex internal structure, thus demanding a highly molding technique and injection die. The most difficult parts of Support elbow injection mould design and manufacture are the design of molding part, injection system, stripping structures. after demonstrated, I choose low-pressure polyethylene as the stuff.  Second, I use Solidworks to do the three-dimensional sculpting for the entity for the sake of deciding the number of swage, equipment of injection, and the place of produce. Third, I choose the parting line, the gate, the sketch of the machinery, and arranged in pairs or groups imoldflow of Solidworks (in this way, we can design the mold’s carrier with effectively).  Next, the machine of take out, fetch, return, and the cool system. The end, I use Solidworks to simulate the machine, besides analyses and check it. In the process, I always find the phenomenon of inconsequence and interference, when this phenomenon happened, I must analyses what’s wrong happened and why. Until I fine the whys, I must modify it. The end, I should decide the rational project. After the project is putted forward, I checked the intension of the pressed part of the mold with FEA of Solidworks. FEA is one of the power functions of Solidworks. After raveling out all problems, I should draw the planar chart. In the process of drawing——transform the three-dimensional chart to planar. In this way, my thinking became very in focus in the process of design, so I spend mostly energy to optimize and consummate the machine, the top-drawer is that we can heighten speed and veracity of drawing. At present, this is very important.

In the process of the design, I used traditionary technique and unconventional ways. Compared them, I found theirs strongpoint and disadvantage, so I can learn from other’s strong points to offset one's weakness. Improving the traditionary technique, besides improve our’s interest to study machine.
