| Abstract: | In this work， we designed an injection mold for the fixing frame of vehicle according to the structural characteristics and test requirements. A bicolor forming process was adopted to meet the requirement for the aspect of the product. This also made the dimensional accuracy of the products reach a MT3 level （GB/T 14486—2008）. The mold realized fully automatic production through a secondary demolding mechanism. The economic benefit of the enterprise was greatly improved， and the mold test was successful at one time. The formed plastic parts meet the requirements for the drop test and the hot and cold impact test. This result proved that the mold structure was advanced and reasonable. |
