[0002] Molds are important process equipment for modern industrial production, meeting the needs of industrial large-scale production. With the rapid development of the alloy industry and the demand for plastic products in major industrial fields including aerospace, electronic machinery, shipbuilding, and automobiles, the structure of alloy products is more complex, and the requirements for the mold structure are also higher and higher. Traditional mold design can no longer meet the production speed and quality requirements of today's plastic products.
[0003] During the processing of automobile parts products, die-casting molds are required to press metal powder into sheet-shaped blanks, and then press the sheet-shaped blanks into the required shapes. For small automobile parts, such as automobile electrode plates, due to the small product volume, it is inconvenient to demold, and it cannot be die-cast in one step. It often requires secondary die-casting. This processing method is to pass the sheet-shaped blank through the die-casting mold, and the mold presses the blank into the required shape during the downward pressing process. However, the die-casting molds currently on the market for stamping sheet-shaped blanks can only form one product at a time, with low efficiency, and cannot achieve continuous stamping during die-casting. At the same time, the pressing knives are fixed, which is inconvenient for maintenance and assembly. At the same time, the die-casting mold structure design is unreasonable, the stability is relatively poor, and the defective rate of processed products is relatively high. For this reason, the inventor designed a four-cavity die-casting mold for automobile parts. Summary of the Utility Model
