3692 斜齒輪組件的成型工藝及塑料模具設(shè)計(jì),齒輪,組件,成型,工藝,塑料,模具設(shè)計(jì) 斜齒輪組件塑料注塑模設(shè)計(jì) 摘 要本設(shè)計(jì)題目為斜齒輪組件塑料注塑模，但對(duì)做畢業(yè)設(shè)計(jì)的畢業(yè)生有一定的設(shè)計(jì)意義，它概括了斜齒輪組件塑料零件的設(shè)計(jì)要求、內(nèi)容及方向。通過(guò)對(duì)該零件模具的設(shè)計(jì)，進(jìn)一步加強(qiáng)了設(shè)計(jì)者注塑模設(shè)計(jì)的基礎(chǔ)，為設(shè)計(jì)更復(fù)雜的注塑模具做好了鋪墊和吸取了更深刻的經(jīng)驗(yàn)。通過(guò)對(duì)方案的選擇：從零件圖上分析：該零件總體形狀為帶凸緣的斜齒輪組件，形狀簡(jiǎn)單，結(jié)構(gòu)合理且制件的壁厚均勻，在兩邊相交的部分也都設(shè)有圓弧過(guò)渡，在成型時(shí)塑料在模具型腔內(nèi)流動(dòng)阻力相對(duì)較小有利于制品的成型。本塑件是斜齒輪組件在齒輪外側(cè)的齒槽與開(kāi)模方向不一致且它們之間有一個(gè)螺旋的角度所以在脫模時(shí)必須考慮設(shè)計(jì)一個(gè)能在開(kāi)模時(shí)隨著開(kāi)模過(guò)程的進(jìn)行使塑件和型腔同時(shí)旋轉(zhuǎn)一個(gè)角這樣才能在開(kāi)模時(shí)順利把制件頂出，在本副模具的設(shè)計(jì)中，在頂管的尾部安裝了推力軸承，在開(kāi)模時(shí)頂桿頂動(dòng)軸承蓋及軸承座使推塊上升，在上升的過(guò)程中，由于塑件及推塊同時(shí)發(fā)生轉(zhuǎn)動(dòng)，直到塑件脫出型腔。這種機(jī)構(gòu)脫?？煽?，設(shè)計(jì)方便且在模具中占用空間較小，非常適合在本副模具中使用。相信不久本模具投入市場(chǎng)一定能帶來(lái)很好的效益服務(wù)大眾，服務(wù)社會(huì)。關(guān)鍵詞：塑料注塑模 斜齒輪組件 推力軸承 軸承蓋 推塊 型腔 The helical gear module note molds the design AbstractThis design topic molds for the helical gear module note, but to the graduate which makes the graduation project has the certain design significance, it summarized the helical gear module plastic parts design request, the content and the direction. Through to this components mold design, further strengthened the designer note to mold the design foundation, for designed more complex casts the mold to complete the upholstery and to absorb a more profound experience.Through to plan choice: Analyzes from the detail drawing: This components overall shape for belt flange helical gear module, shape simple, the structure reasonable also workpiece wall thickness is even, in the part which two intersects also all is equipped with the circular arc transition, when taking shape the plastic the flow resistance relative is slightly advantageous in the mold cavity to product taking shape. This models is the helical gear module with opens the norm in the gear flank socket to not to be inconsistent also them between has a spiral angle therefore in drawing of patterns time must consider designs to be able while operates the mold along with to open the mold process to carry on causes to model and the cavity revolves an angle to be able when operates the mold smoothly the workpiece to go against like this, in this mold design, has installed the thrust bearing in the top pipe rear part, when operates the mold the roof bar goes against moves the bearing cap and the bearing seat causes to push the block rise, in rise process, because models and pushes the block synchronize rotation, Until models the leaving cavity. This kind of organization drawing of patterns reliable, the design convenience also takes the space in the mold to be small, suits extremely in this mold uses. Can unquestionably bring very good benefit and serve the general public to invest the market while believing a mould soon, serve the society.
