How to control the finishing of non-standard mold parts

a whole set of mold is composed of many mold parts, among which the non-standard mold parts directly affect the quality of the mold, while the quality of non-standard mold parts is completed by finishing. How to control the finishing of non-standard mold parts

1. In general mold parts manufacturing enterprises, precision machining generally adopts grinding, electric machining and fitter

2. Mold finishing control:

a: mold non-standard parts processing, For different (for example, the clamp clamping surface of samples such as plastic film and fiber wire is processed adaptively with the same material as the technical requirements, which has certain plasticity, and can achieve good processing effect through the control of processing;

b: according to the different appearance and shape of parts, we have tested many times during the original research and development, and can roughly divide the parts into three categories: shaft, plate and special-shaped parts. The common process is roughly: rough Processing heat treatment (quenching and tempering), fine grinding, electrical machining, fitter (surface treatment), assembly and processing

3. Grinding of parts

the main feature of the first dentalmodel used in grinding is that there are three main types of machine tools with high precision: surface grinder, internal and external grinder and tool grinder. During finishing grinding, the generation of grinding deformation and grinding cracks should be strictly controlled. Even very small cracks will be exposed in subsequent processing and use. Therefore, the feed of fine grinding should be small and not large, the coolant should be sufficient, and the parts with dimensional tolerance within 0.01mm should be grinded at constant temperature as much as possible

4. Heat treatment of parts:

the heat treatment process of parts, while making the mold parts obtain the required small panel control system, the advantage lies in the control hardness of the experimental machine, but also needs to control the internal stress to ensure the dimensional stability of parts during processing. Different materials have different treatment methods
