초록
In this study, the injection pressure of 31 MPa and clamping force of 1,000 kN toggle electric injection molding machine were used to measure the load transmitted to the frame during injection molding and to use it as the design basis data. In general, the toggle structure is composed of a movable plate, tie bars, crossheads, toggle links, toggle pins, base plates, etc and The material is spherical graphite cast iron(FCD 400). In this study, it was found that there was a 1.3% safety factor by calculating the clamping force in the structure of the five-point toggle link system. In addition, Expected static bottom load, Expected dynamic additional load, Maximum expected additional load, and Maximum weight load were measured using tensile measurements and presented as important basic design data of the assembly.
