Description

Technical Field

[0001] The utility model relates to the technical field of die-casting equipment, in particular to a die-casting mold with a grid pattern surface. Background Art

[0002] Common automobile torque converter housings, automobile transmission housings, automobile valve bodies, automobile clutch housings, automobile torque converter housings, automobile upper and lower housings, and automobile transmission housings are produced through die-casting molds.

[0003] After die-casting is complete, water cooling is often used to quickly cool the mold. This method uses water as the cooling medium, which is introduced into the mold through a circulating water supply system to reduce the mold temperature. Water cooling is suitable for most die-casting molds. However, existing water cooling systems often use pipes to transport water. This results in faster cooling in areas closer to the pipes, while slower cooling in areas farther from the pipes. This uneven cooling can cause internal stress in the product due to solidification shrinkage. This can lead to cracks in thin-walled areas of the product when the mold is cooled, due to insufficient strength in these areas. Utility Model Content

[0014] Furthermore, a roller is installed at the bottom end of the water tank, and the roller is synchronously installed at the bottom of the support block, and a water inlet pipe and a water outlet pipe are installed at one end of the water tank.

[0015] Furthermore, the interior of the water tank is equipped with partition 1, partition 2 and partition 3 for separating the inner cavity of the water tank, and partition 1 and partition 2 are horizontal plates, and partition 3 is a vertical plate. Partition 3 divides the inner cavity of the water tank into a left cavity and a right cavity, and partition 1 and partition 2 divide the right cavity of the water tank into an upper cavity, a middle cavity and a lower cavity.
