| Abstract: | For the thin wall wheel cover with a wall thickness of 1.5 mm, a two cavity mold design plan was made. By optimizing the die structure, including increasing the exhaust insert, adjusting the gate size and size, optimizing the product structure and adding the drainage way, the present situation of filling dissatisfaction of the thin-walled wheel housing was improved, and the appearance quality of zero parts was improved, and the injection production efficiency was improved. The purpose of reducing die cost was achieved. |
