Classification of Mold Components Based on Working Conditions
Mold components can be classified into the following categories based on their working conditions:
- Cold Working Mold Components:This category includes components such as cold stamping molds, cold heading molds, cold extrusion molds, deep drawing molds, wire drawing molds, thread rolling molds, and shearing molds. These molds are designed to perform under cold working conditions and are used for shaping materials without the application of heat.
- Hot Working Mold Components:This group comprises components like hot forging molds (including hot forging molds, high-speed hammer forging molds, and precision forging molds), hot extrusion molds, hot blanking molds, and die-casting molds. These molds are utilized in processes involving high temperatures, which allow materials to be more easily shaped and formed.
- Forming Mold Components:This category includes molds used for forming plastics, rubber, ceramics, glass, and powder metallurgy. Plastic molds, for example, are typically designed to operate within a hardness range of 45 to 60 HRC.
In summary, mold components are classified based on their working conditions into cold working, hot working, and forming categories. These components are indispensable and complementary parts in mold processing. Key mold components include punches, punch heads, guide pillars, guide bushings, ejector pins, core pins, ball cages, oil-free guide bushings, oil-free slide plates, and guide pillar assemblies. Each type of mold component serves different functions within the mold, tailored to specific operational requirements and conditions.
