斜三通管塑料注塑模结构与设计(含任务书开题报告,中期检查报告表,论文说明书11000字,cad图纸12张合一)
摘要
本设计的成品为一下水道用的斜三通管子，在设计过程中按以下步骤设计模具：斜三通注塑模工艺规程的编制—注塑模的结构设计—模具设计的有关计算—模具加热与冷却系统设计—模具闭合高度的确定—注塑机有关参数的校核，最后是绘制模具总装配图。在注塑模艺规程的编制的过程中，要着重分析制品原材料（UPVC）的各项成型工艺参数；在模具结构设计中应注意的是斜导杆起成型兼顶出的作用；模具设计计算的要点是型腔与型芯径向尺寸及深度方向尺寸的计算，型腔与型芯的计算在整个设计过程中显得尤为重要，因为它们直接关系到制品的尺寸精度；模具总装图和非标准零件图用AutoCAD画出，图中需标注的各项参数如尺寸，公差，技术要求，图纸布局等均应按国家标准设计。设计中出现的标准件如推板，螺钉等的零件图无需一一画出，但应参照文献查出其具体结构尺寸。

Abstract
The finished product of this design for a the thin wall box cover, at design to press in the process following step design molding tool:A cover notes the establishment of the Plastics mold craft rules distance- note the structure design- molding tool design of mold of Plastics relevant calculation- the molding tool heats to design with cooling system- the molding tool shuts to match height really settle- note the pit in the machine of Plastics school concerning parameter, finally is to draw the total assemble diagram of molding tool.In the process of note establishment of the Plastics mold skill rules distance, the heavy analysis of important step products each item of the original material( HDPE) to model the craft parameter;In the molding tool structure design should what to notice is inclined to lead the pole to rise to model and the function of the a;The molding tool designs the calculation that the calculating important point is a Cave mold and a Plastics paths toward size and the depth direction size, a Cave mold and the calculation of a Plastics seem to be as importance in the whole design process, because the size accuracy that they relate to the ware directly;The molding tool is total to pack the diagram and not standard spare parts diagrams to draw with the AutoCAD, various parameters,such as size, business trip, that need to be marks in the diagram, technique request, the diagram paper layout etc. all should press national standard design.Design the standard piece of medium emergence if push the plank, the bolt spare parts diagram of etc. did not need 11 draw, but should according to the cultural heritage to look up it concrete structure size.
