What is the function of reinforcing ribs on the cast iron platform for marking lines

The reinforcing ribs of cast iron welded flat plates are an indispensable part. The reinforcing ribs on the cast iron welding plate can increase the rigidity and strength of the cast iron welding plate like "I-shaped" iron, without significantly increasing the cross-sectional area of the cast iron welding plate. However, it is difficult to cast a cast iron welded flat plate without reinforcing ribs. Reinforcing ribs can serve as internal flow channels for the cast iron welded flat plate, helping to fill the mold cavity and playing a significant role in assisting the injection of molten iron into the support section of the cast iron welded flat plate. For some parts that are frequently subjected to pressure and torque, it is also easy to damage the overall accuracy of the cast iron welded flat plate. Due to the use of reinforcing ribs in the inspection marking plate, the structural strength of the cast iron mold can be improved, which is beneficial in preventing cracking due to excessive internal stress; And due to the use of cast steel material in the body, the strength of the cast iron mold against thermal expansion and contraction is increased. Even if cracks occur, they are easy to weld and repair, making them reusable and extending their service life. When designing reinforcement bars for cast iron welded flat plates, they are generally arranged on the bottom non-contact surface, and their extension direction follows the direction of product stress and offset. The selection of reinforcement bar positions should be based on some production considerations. The length of the reinforcing rib should be consistent with the length of the cast iron welding plate, and the extension of the cast iron welding plate should be connected at both ends, or the overall length of the cast iron welding plate should be the same. The simple shape of the reinforcing ribs in the cast iron welded flat plate is several reinforcing ribs forming many square or rectangular grids attached to the bottom surface of the cast iron welded flat plate. However, in order to meet some production or structural requirements, the shape and size of the reinforcing ribs can be changed according to actual requirements. The simpler shape of the reinforcing rib for the cast iron welded flat plate is a rectangular column attached to the bottom surface of the cast iron welded flat plate. However, in order to meet some production or structural considerations, the shape and size of the reinforcing rib need to be changed. The rectangular reinforcing ribs change shape to make production easier. The two sides of the reinforcing ribs are added with mold exit angles to reduce the friction force during demolding and ejection. The bottom of the product is connected with rounded corners to prevent excessive stress concentration. The design of the rounded corners also provides a gradual shape for the flow channel, making the mold cavity filled smoothly. According to its structure, cast iron welding plates can be divided into ribbed plate and box type. Reasonable design of the thickness, height, and number of passes of the reinforcing ribs plays an important role in the accuracy of cast iron welding plates. Cast iron welded flat plates are suitable for various inspection work and serve as reference planes for precision measurement. They are mainly used as reference planes in mechanical workpiece inspection and measurement to check the dimensional accuracy or behavioral deviation of parts. From this, it can be seen that the bottom design of the drawn cast iron flat plate is to increase the stability of the cast iron welded flat plate by enclosing and reinforcing the plate. The internal design reinforcement ribs of cast iron welded flat plates are generally spaced 500mm apart. If the specifications of cast iron welded flat plates are smaller, they can also be designed according to the actual situation. The bottom design of the enclosure and reinforcement plate is to enhance the stability of the cast iron welded flat plate. The cast iron mold used for marking cast iron welding plates includes several reinforcing ribs, which are respectively set at the bottom of the body corresponding to the bottom of the casting groove, and the upper end of the reinforcing ribs is connected and fixed to the bottom of the body.
