Auto part molds refer to tools used for manufacturing automotive components. They are typically made of metal materials and feature high precision, durability, and reusability. Auto part molds include various types of molds such as injection molds, die-casting molds, and stamping molds.
Injection molds are used for manufacturing plastic parts. Through the injection molding process, molten plastic material is injected into the mold and then cooled and solidified into shape. Injection molds typically consist of a mold base, cavities, cooling system, and ejector pins.
Die-casting molds are used for manufacturing metal parts. By injecting molten metal material into the mold and applying a certain pressure, the material fully fills the mold cavity. After cooling and solidification, the part is removed from the mold. Die-casting molds generally consist of a mold base, casting cavity, cooling system, and exhaust system.
Stamping molds are used for stamping processes on metal sheets. Through the vertical movement of the mold and the deformation of the metal sheet, the sheet is stamped into the desired shape according to the mold. Stamping molds usually comprise an upper mold, lower mold, mold base, and guiding devices.
Auto part molds play a crucial role in the automotive manufacturing process. They ensure the quality and precision of automotive components, increase production efficiency, and reduce costs. They are widely applied in automotive part manufacturing, automotive shaping processes, and automotive repair fields.
Release of car body process digital model
The car body design department releases the product digital model. Engineering personnel from the engineering development department conduct preliminary process analysis and quotation based on this product digital model (used for tender comparison data) and use the car body process digital model for mold bidding and corresponding process analysis. The bidding process is not discussed in detail here. Below, the mold development management is briefly discussed after the finalization (i.e., determining the mold manufacturer).
Feasibility analysis of car body part manufacturing process (mold developer and engineering development department)
Upon receiving the car body process digital model, the mold developer conducts a feasibility analysis for each part. It is generally required that the mold manufacturer performs a CAE analysis (i.e., part forming simulation analysis) for all newly developed parts.
DL drawing design and signing
After the CAE analysis, the DL drawing design can proceed, often simultaneously. DL drawing design, i.e., design layout—stamping process analysis design, can also be referred to as the mold process flow chart. It includes: the part's blanking sheet size, stamping direction and angle, stamping process arrangement, feeding direction, waste knife distribution and edge direction, waste disposal direction diagram, CH hole, left and right part identification, process labeling, etc. The DL drawing must also reflect related process stamping equipment, mold height, mold material, the operating stroke of the drawing die or pressure plate, sheet positioning method, and pressure analysis of the completed process.
Design and signing of auto part mold structure diagrams
The sequence of mold structure diagram signing: drawing mold diagram signing—shaping and flanging mold signing—trimming and punching mold signing. Since the casting and machining cycle of auto part molds are rigid timeframes and cannot be compressed, ensuring the project's progress requires that the design of auto part mold structure diagrams is very important. It is necessary to advance the mold design phase as much as possible to secure the time for subsequent mold manufacturing.
