把手注塑模三維設(shè)計及數(shù)控仿真加工

摘 要：本設(shè)計是把手注塑模具的設(shè)計，在正確分析塑件工藝特點和ABS的材料性能后，采用了一模一腔、點澆口的澆注方式。主要對模具型腔數(shù)目、注塑機的選擇、凸模、凹模的澆注系統(tǒng)、脫模機構(gòu)、合模導(dǎo)向機構(gòu)、冷卻系統(tǒng)和側(cè)向分型抽芯機構(gòu)進(jìn)行設(shè)計計算，其中重點對模具的冷卻系統(tǒng)、側(cè)向分型抽芯機構(gòu)進(jìn)行了計算。運用AutoCAD軟件完成模具的裝配圖，并使用Pro/E軟件對模具的零件進(jìn)行三維實體造型和裝配。最后使用Mastercam軟件對模具進(jìn)行數(shù)控仿真加工，目的是生成數(shù)控加工NC代碼，可提高效率和避免人工編程的錯誤，有效控制模具設(shè)計的成本。

Handle Three-dimensional Design and NC Machining Simulation of Handle Injection Mold

Abstract: The handle design is the design of injection mold, plastic parts in the correct analysis of process characteristics and material properties of ABS, the use of a cavity of a mold, the pouring gate way point. Mainly on the number of mold cavity, the choice of injection molding machine, punch, die casting system, Demoulding agencies Die-oriented institutions, the cooling system and the lateral sub-type core-pulling mechanism design, of which focus on the mold cooling system, the lateral sub-type core-pulling mechanism calculated. The use of AutoCAD software to complete the mold assembly and the use of Pro / E software for the mold parts and assembly of three-dimensional solid modeling. Finally, the use of Mastercam software simulation tool for CNC machining, CNC machining objective is to generate NC code, will increase efficiency and avoid errors in manual programming to effectively control the cost of die design.

Keywords:Three-dimensional design; simulation processing; injection molding
