斜齿轮组件的成型工艺及塑料模具设计(含任务书,开题报告,中期检查报告,毕业论文说明书10000字,cad图纸15张零件图1张装配图)
摘   要
本设计题目为斜齿轮组件塑料注塑模,但对做毕业设计的毕业生有一定的设计意义,它概括了斜齿轮组件塑料零件的设计要求、内容及方向。通过对该零件模具的设计,进一步加强了设计者注塑模设计的基础,为设计更复杂的注塑模具做好了铺垫和吸取了更深刻的经验。
通过对方案的选择:从零件图上分析:该零件总体形状为带凸缘的斜齿轮组件,形状简单,结构合理且制件的壁厚均匀,在两边相交的部分也都设有圆弧过渡,在成型时塑料在模具型腔内流动阻力相对较小有利于制品的成型。本塑件是斜齿轮组件在齿轮外侧的齿槽与开模方向不一致且它们之间有一个螺旋的角度所以在脱模时必须考虑设计一个能在开模时随着开模过程的进行使塑件和型腔同时旋转一个角这样才能在开模时顺利把制件顶出,在本副模具的设计中,在顶管的尾部安装了推力轴承,在开模时顶杆顶动轴承盖及轴承座使推块上升,在上升的过程中,由于塑件及推块同时发生转动,直到塑件脱出型腔。这种机构脱模可靠,设计方便且在模具中占用空间较小,非常适合在本副模具中使用。相信不久本模具投入市场一定能带来很好的效益服务大众,服务社会。 [资料来源:http://doc163.com]

The helical gear module note molds the design      
Abstract
This 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. [资料来源:https://www.doc163.com]
