Any of various tools used in the mold industry to produce desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. In short, a mold is a tool used to make a molded item. This tool is made of various parts, and different molds are made of different parts. The following Xiaobian introduces the content of precision mold processing process arrangement and service life, welcome to read!

Mold processing process arrangement:

1, bottom processing, processing quantity guarantee;

2. Casting blank datum alignment, 2D and 3D profile allowance check;

3. 2D and 3D surface rough processing, non-installation non-working surface processing (including safety platform surface, buffer mounting surface, platen plane, side datum surface)

4. Alignment of the side datum surface to ensure accuracy before semi-finishing;

5, semi-finishing 2D, 3D surface, finishing all kinds of installation face (including limit block installation surface and contact surface, insert installation surface and against the back, punch installation surface, waste cutter installation surface and against the back, spring installation surface and contact surface, all kinds of travel limit working surface, oblique wedge installation surface and against the back), semi-finishing all kinds of guide surface, guide hole, Reserve the finishing process reference hole and height reference surface, and record the data;

6. Check and review the machining accuracy;

7. Fitter inlaying process;

8. Before finishing, straighten the datum surface of the process reference hole and check the allowance of the insert;

9. Finishing surface 2D, 3D, side punching surface and hole position, finishing technology reference hole and height reference, finishing guide surface and guide hole;

10, check and review the processing accuracy.

Precision mold processing life:

First, the main factor of precision die processing is corrosion failure. When the mold hardness is high, the corrosion resistance is good, if the mold hardness is not good, the corrosion resistance is not good.

Two, thermal fatigue crack damage failure, injection molding, mold under the action of cold and heat repeatedly formed, the formation of surface and internal deformation, involving repeated cyclic thermal stress, tissue damage and loss of toughness, resulting in microcracks, and continue to expand, once the crack expansion, metal melting, repeated mechanical stress accelerated crack expansion.

Therefore, on the one hand, the mold should be preheated. In addition, in the production process, the mold should be kept in the corresponding working temperature range to avoid early cracking failure. At the same time, the precision mold processing before production and internal reasons do not appear problems. Due to the actual production, the mold failure is mainly thermal fatigue cracking failure.

Three, fracture structure failure, under the action of pressure, the mold will be in the development of weak crack initiation, precision mold processing forming surface marking traces or electrical processing traces have not been polished, or a molding at the clear Angle will appear some fine cracks, when there is a brittle phase or grain boundary coarse, it is very easy to fracture. Therefore, all the scratches and electrical machining marks on the working surface of the mold should be polished, even if it is in the main part of the whole pouring operation, it should also be polished.
