摘要
本次畢業(yè)設(shè)計主要是對斜齒輪注射模的設(shè)計，包括工藝方案的分析及確定、工藝計算、模具結(jié)構(gòu)設(shè)計計算等內(nèi)容。由于該塑件是傳動工程件且阻滑紋為圓柱紋，故在設(shè)計中主要解決了該塑件的分型面選擇、型腔數(shù)目的確定、脫模機(jī)構(gòu)的設(shè)計。采用了旋轉(zhuǎn)機(jī)構(gòu)、轉(zhuǎn)盤式分型抽芯機(jī)構(gòu)來脫模。從而保證了齒輪的精度、其孔的同軸度和螺旋齒廓的精度。
關(guān)鍵詞：注射模；斜齒輪；結(jié)構(gòu)設(shè)計
Abstract:
The main design graduate of bevel wheel injection, including the analysis of the program and determine, process. Mold design calculations content. Since the drive is plastic parts and pieces of the project profile for the anti-skid cylindrical profile. Therefore, the design is the main settlement of the plastic parts of sub-surface choices, determining the number of cavity, the demoulded mechanism design, Using a rotating body, turntable type pulling mechanism to demould. Thereby ensuring the accuracy of the gear,the concentricity of the socket and spiral profile accuracy.
