Problems solved by technology

[0007] Gray cast iron (FC30): serious pollution in the casting process, high energy consumption, long cycle time, difficult processing, increasing overall cost, low strength and fatigue;
[0008] At present, the common problem of polymer alloy molds in the market is that the hardness of the molds is insufficient, and the number of pressed metal sheets is less than 200 pieces, which cannot reach an economical scale;
[0009] Alloy materials, high cost, rapid trial mold zinc-based alloy (ZAS) is a recyclable mold material, melted at 550 ℃ and returned to the furnace, the casting cycle is about a week faster than FC30, but the hardness is lower, and about 100 stamping parts need to be repaired Molds, thin plates and shallow stretched parts will be used. Due to the low strength of low melting point alloy materials (the tensile strength is only about 60MPa), it is not very suitable for plates with a thickness of more than 1.5mm.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a metal-based polymer material, a polymer composite material and a mold prepared therefrom. Background technique [0002] Trial production of automobile products generally takes place when vehicle manufacturers need to launch new models or modify or upgrade existing models. The objects of trial production of automobile products mainly refer to prototype cars, body parts, body parts, interior and exterior trims and components. There are generally three types of prototype cars: concept car, verification car and test car. The concept design focuses more on appearance and shape; while the design and trial production of verification cars and test cars puts more emphasis on reasonable size and qualified quality. Most of the trial-produced parts in the trial-prototype car are stamped and sheet metal parts, and cold stamping technology is generally used to form v...
