During the processing of molds, it is necessary to follow the prescribed procedures to ensure the accuracy of the molds and the quality of the products. The processing of molds is a complex process, and it is even more important to make this process precise during processing. What is the mold processing flow? Let's talk about it in detail below.  

The mold processing process generally includes: preparation of mold blanks - rough machining of parts - semi precision machining - heat treatment - precision machining - surface treatment of mold cavity - mold assembly - machine debugging.  

1、 Die blank prepaation

Most mold blanks are made of metal. Taking forging as an example, the raw materials used for forging are generally rods, plates, and pipes. The operator mainly selects based on the specific shape and geometric dimensions of the blank. For thin plate blanks, ordinary punching or precision punching can be used for cutting. If forging ring parts is required, pipe cutting can also be used to make blanks.  

2、 Rough machining of parts

For rough machining of parts, we take milling as an example. As long as the outer contour and islands of the part are given, a machining trajectory can be generated. And it can automatically add arcs at the sharp corners of the trajectory to ensure smooth trajectory and meet the requirements of high-speed machining. Mainly used for milling flat surfaces and grooves. Multiple contours and islands can be selected for processing.

3、 Semi precision machining

The semi finishing stage is to complete the machining of the secondary surface and prepare for the finishing of the main surface.

4、 Heat treatment

Heat treatment is a comprehensive process in which materials are heated, insulated, and cooled in a certain medium, and their properties are controlled by changing the surface or internal structure of the material. The heat treatment process generally includes three processes: heating, insulation, and cooling, sometimes only two processes: heating and cooling. These processes are interconnected and uninterrupted.

5、 Precision machining

The machining allowance for precision machining is smaller than that for rough machining. It is important to select appropriate tools for cutting, control the speed and rotation of the tools, and pay attention to the size, glossiness, and appearance of the materials.

6、 Surface treatment of cavity

Different surface treatment methods for molds can change the chemical composition, structure, and properties of the mold surface, greatly improving and enhancing the surface properties of the mold. For example, hardness, wear resistance, friction performance, demolding performance, thermal insulation performance, high temperature resistance, and corrosion resistance. This step is of great significance for improving the quality of molds, significantly reducing production costs, improving production efficiency, and fully tapping into the potential of mold materials.

7、 Mold assembly

The process of assembling parts into components according to certain technical requirements, and combining them into components to form the entire machine. There are two forms of assembly, one is fixed assembly and the other is mobile assembly. Different batches of production use different assembly methods.  

During the assembly process, certain mold parts need to be polished and trimmed. The main content of mold assembly is to assemble the processed mold parts and standard components into a complete mold according to the requirements of the mold assembly drawing. After the trial mold, some parts need to be adjusted and trimmed to ensure that the parts produced by the mold meet the requirements of the drawing, and that the mold can work continuously normally before the mold processing is considered complete.
