Cold and warm die forging machine manufacturers tell you that when designing die forgings, certain criteria should be followed in the selection of parting surfaces. First, all or most of the die forgings should be located in the same sand mold, or the main machining surface and the machining datum should be located in the same sand mold to prevent forming errors. To ensure the dimensional accuracy of castings, it can facilitate forming and forming operations.

Cold and warm die forging machine manufacturers tell you that if the die forging has many machined surfaces and it cannot be placed on the same side of the parting surface as the reference surface, the machined reference surface and most machined surfaces should be located on the same side. the same side of the profile. At the same time, the number of parting surfaces should be reduced as much as possible, so that only one parting surface can be reduced, which can simplify the operation process and improve the casting accuracy.
When selecting the parting surface for die forging, the cavity and the main core should be located in the lower mold as much as possible to facilitate forming, lowering the core, forming and viewing the cavity size. However, the lower cavity should not be too deep, and the use of hanging cores and large hanging sand should be avoided as much as possible. Cold and warm die forging machine manufacturers tell you to choose the flat surface as the parting surface as much as possible, and use less curved surface to simplify the molding process. Minimize the number of cores and moving blocks to simplify molding, modeling, installation, and more.
In addition, the parting surface should be selected at the large section of the die forging to ensure that the die can be taken out without damaging the die. The cold and warm die forging machine manufacturer tells you that when selecting the parting surface of the casting, in order to ensure the quality of the casting, the sand mold should be avoided as much as possible after the mold is closed. Generally, the pouring orientation should be determined first, and then the parting surface should be considered.
Cold and warm die forging machine manufacturers tell you that for die forgings with low quality requirements, the parting surface that can simplify the process should be selected first. high quality.
