What are the main points of using standard parts of molds?

In industrial production since the mold, the efficiency of a lot of work has been greatly improved, especially the emergence of mold standard parts, so that the abrasive industry has become more standardized, manufacturing and use of the process has been more convenient. However, in order to better protect the standard parts of the mold from damage, the following points should be mastered when using.

What are the main points of using standard parts of molds?

First, reasonable selection and dressing of grinding wheels

When using mold standard parts, white corundum grinding wheel should be used as much as possible, because the grinding wheel made of this kind of meat is relatively hard and brittle, so it can achieve a good use effect, and it is very easy to produce a new cutting edge. Mold standard parts manufacturers emphasize that, especially in fine grinding, it is more necessary to choose a good grinding wheel, and then select a grinding wheel made of the right material for the steel condition used in the mold.

Second, the rational use of cooling lubricant

The role of cooling washing and lubrication should be played as much as possible, so that the heat generated in the grinding process can be better controlled within the allowed range, so as to prevent the workpiece from deformation because it is too hot. At the same time, attention should also be paid to improving the relevant cooling conditions, such as the use of internally cooled grinding wheels, etc., and the cutting fluid should be introduced into the center of the grinding wheel, and the cutting fluid can directly enter the grinding area to play an effective cooling role in order to prevent surface burns of the workpiece.

Third, the quenching stress after heat treatment should be reduced to a minimum

Because the mold standard parts manufacturers found that in the process of operation may be due to the quenching stress and other forces, resulting in a series of changes that cause the workpiece to crack. Therefore, mold standard parts manufacturers remind that it is necessary for high-precision molds to eliminate the residual stress of grinding, low temperature aging treatment should be carried out after grinding to improve toughness.

The above are several aspects of the main points of the use of standard parts of the mold, in addition, for the more precise grinding of very small size, it is especially necessary to pay attention to the control of temperature, and it must be ground at constant temperature. Because there is a little change in temperature, it may cause changes in the product and affect the accuracy, so we must carry out reasonable control in this respect.
