초록

This study investigates the effect of the gate position on the deformation of injection molded products during injection molding. This study was conducted with four types of gate conditions using the CAE analytical method.

As a result of analysis according to each gate condition, the heat distribution and deformation of the injection molded product owing to the filling of the resin in the mold were considered. As a result, displacement occurred in the injection molded product owing to the imbalance of thermal stress during the resin filling process, and it was verified that relatively stable injection molded products could be manufactured in the first and third of the four types of gate conditions.

Keywords:

Injection mold, Thermal stress, Heat distribution, Filling conditions, Mold deformation, Computer aided engineering (CAE)
