The use and management of precision casting molds

Mold is the primary fixture in precision casting production, which determines the dimensional accuracy and surface roughness of castings. Many times, the use and management of molds are often superficial, which not only fails to play their role but also greatly reduces their lifespan. This is something that precision casting enterprises should avoid. Today, precision casting manufacturer Tianyao Metal will talk to you about the use and management of precision casting molds.

Precision casting molds generally include the cavity, core, forming part, positioning and guiding part, locking part, ejection part, etc. Each part has its own unique function. The forming part mainly forms the appearance and inner holes of the casting, such as the cavity, core, etc; The positioning and guidance part is mainly responsible for determining the position between modules and guiding the position of cores and active blocks, such as positioning pins, guide pillars, etc; The locking part is mainly responsible for fixing the mold blocks, such as bolts and screws; The ejection part is mainly responsible for the molding of wax parts. The above are all important components of the mold. But there is another important part of the mold, which is the parting surface.

The parting surface is an interface designed by humans to divide a casting into multiple parts based on factors such as the structure of the casting itself, the ease of mold manufacturing, and the accuracy of the casting. Because it involves multiple considerations, the parting surface is also an important component of the mold.

So how should molds be used and maintained? Firstly, before using the mold, it is important to carefully understand its structure, how to open the mold, how to position the core and active blocks inside, and the installation sequence; Secondly, during the use of the mold, it is advisable to avoid scratches and impacts on the mold, especially on the core, live blocks, positioning pins, guide pillars, and parting surfaces. Furthermore, during the production of wax parts, compressed air and wooden tools should be used as much as possible to clean the mold. When pressing the mold, the mold should be placed directly below the press plate, and the locking mechanism of the mold must be balanced. If the mold is damaged, it must be repaired in a timely manner, and the size of the wax parts should be checked for correctness. In addition, mold maintenance is also an important aspect of mold management. After using the mold, it is necessary to immediately clean the wax stains on it and wipe it with a dry cloth. If it is not used for a long time, the mold positioning and guiding system should be cleaned and the forming system should be stored in the mold warehouse for unified management.

Of course, mold management also includes establishing accounts, placing molds (distinguishing between commonly used and infrequently used, major and light), placement positions, mold usage and maintenance records, etc. In short, the management of a mold library can truly reflect the management status of an enterprise and should not be underestimated.
