The injection mold design of auto right turn signal visor fixation
Abstract The mask and holders was fixed on the auto right turn signal visor fixation, it primarily had warping, distortion and other shortcomings. In order to solve this problem, the proper three dimensional plastic production molding was built and then generated two-dimensional engineering drawings. With analyzing its characteristics, identifying that it needed side core-pulling mechanism. Slider, wedged tight, springs and secondary were presented to combine in order to finish side ejection mechanism. After studying the characteristics of injection molds, the tradition of the second ejection mechanism and the means of fixation of puller rod were improved. By Pro/E analysis and according to actual conditions to determine the appropriate gate locations of plastic production, the right gate was selected with various comparison, where the exhaust system was based on the bubble position analysis, and the cooling systems was determined according to the cooling quality. Checking the selection of injection molding machine and mold was repeated to determine the most appropriate solution. Results showed that the mold design was reasonable and it could realized an injection molding.
