This topic was developed for business needs an economical small - scale injection molded parts runner automatic cutting device . It can replace the workers runner shear injection molded parts in a poor working environment , without artificial and unattended , thereby greatly reducing the labor intensity , reduce labor costs , suitable for promotion and application . This is a good reference on the development of other small -scale injection molded parts runner shear device fill the blank of China in this field . Firstly, the function of the small - scale injection molded parts runner shear device , cutting device system is decomposed into injection molded parts positioning mechanism , the shear mechanism , the transport mechanism , the four components of the control system, etc. , and draw the system work cycle Figure ; formulated injection molded parts runner relative to the the shear tool positioning program , and positioning mechanism to carry out the detailed design ; comparative analysis to determine the injection molded parts runner shear \and a cam mechanism - shear institutions , the institution conducted a comprehensive , structural design, the last parts of the parameters calculated shear mechanism driving its selection detailed analysis ; runner shear after injection molded parts transferred divided into pick-and-place and moving bodies of two parts , the true air claw pick and place mechanism composed of its components selection ; comprehensive analysis of the moving mechanism of the plane four institutional composition , scale , and focuses on the the true air influential factors in the the claw mounting plate angle error , its error compensation method ; doing a study on the control system , drawn up according to the cutting device system work cycle diagram of the control scheme of the system , and system hardware, system software are analyzed . with an introduction . Finally , the experimental prototype positioning and shear tests of the injection molded parts , transferred to test for the existing problems in the test , the proposed improvement measures , improved shear device testing to verify the positioning mechanism , the cutting mechanism , the transport mechanism , the control system is feasible, and reliable , and its performance are to meet design requirements. The small -scale injection molded parts runner automatic cutting device has good practical value .
