Determination of mold base and insert dimensions The size of the wire drawing die mainly depends on the size and structure of the plastic product. For molds, the more compact the structure, the better, while ensuring sufficient strength. The size of the insert can be determined based on the external dimensions of the product and the structure of the product itself. After determining the size of the insert, you can roughly determine the size of the mold frame. 2. Selection of insert material The performance of die insert materials for wire drawing molds mainly includes four aspects: hardness, wear resistance, strength and toughness, and corrosion resistance. The selection of mold insert materials mainly depends on the volume and type of plastic product. These products are ordinary plastics, such as ABS, PP, PC, and other plastics. P20 type and other types of pre quenched and tempered steel are commonly used. If the product batch is large, quenched and tempered steel, such as H13 type, should be used. 3. Determine the height of the square iron The height of the square iron should ensure sufficient ejection stroke, and then leave a certain margin to ensure that when the ejector is fully ejected, the fixed plate of the ejection pin will not touch the movable template or the movable mold support plate. 4. Determination of the overall structure of the mold base After the basic selection of the mold base, the overall structure of the frame should be checked to see if the determined mold base is suitable for the selected or customer specified injection molding machine, including the size, thickness, large mold opening stroke, ejection method, and ejection stroke of the mold base. The above is an introduction to the selection of mold bases and inserts for wire drawing dies. I hope you can understand.
