Design and Cooling Performance of Plastic Injection Mold
Abstract
The use of plastic products has increased considerably in the last century. Plastic products are used in many areas and places in our daily lives. Injection molding is the most widely used method in the production of plastic products. In this study, the mold design of a selected plastic part was made in a computer environment. The improvements required and made during the design are explained. While designing the plastic part, the draft angle was given to the surfaces required for the plastic part to come out of the mold comfortably. Since the plastic part will make some shrinkage when the plastic part is left to cool, the plastic part dimensions were increased by 5% by the standards while designing the mold design. Considering that the raw plastic material can reach the mold cavities most easily, the runner design was made. Analysis of the mold design was carried out. The calculations required for the cooling system were made and cooling channels were designed. At the end of the part production in the plastic mold, the cooling process was analyzed using the package computer program and the results were examined.
