Problems solved by technology

These methods have been well applied in actual engineering, but there are still some shortcomings, such as low-melting point alloy molds need to be cast in a special melting box, the process is complicated, and stamping samples are required first, which is not suitable for the development of new models , the thermal expansion and deformation of the sheet metal sample during casting will affect the precision of the mold; the casting temperature of zinc-based alloys is generally above 400°C, which requires high casting technology and models, and is generally only used to make stamping dies; epoxy resin mold manufacturing process Relatively simple, but slightly inferior in strength and surface wear resistance

The final die is grad layer structure, each layer has different mechanism performance, easy to display material speciality. The invention simplifies the craft and reduces the cost.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology and relates to a rapid mold manufacturing method, in particular to a rapid manufacturing method of a stamping die for an electric arc sprayed automobile cover part. Background technique [0002] The so-called rapid mold manufacturing technology is aimed at the traditional CNC machining steel mold. Rapid molds (or simple molds) generally have the characteristics of short molding cycle and low cost, and are suitable for trial production of new products or small batch production. In the past, the techniques that were often used to make simple molds for automobile panels mainly included low-melting point alloy molds, zinc-based alloy molds, and epoxy resin molds. These methods have been well applied in actual engineering, but there are still some shortcomings, such as low-melting point alloy molds need to be cast in a special melting box, the process is complicated, and stamping sampl...
