A water-cooled dual-clutch housing die-casting mold

Abstract

The invention belongs to the technical field of die casting molds, and provides a die casting mold of a water-cooled double-clutch shell. The die casting mold comprises an upper template, an upper module, a lower template and a lower module; an injection molding mold cavity is formed between the upper module and the lower module; a clutch shell is arranged in the injection molding mold cavity of the die casting mold; three vacuumizing side pressing mechanisms are arranged on the side edge of the die casting mold; and a water cooling runner device is arranged in the injection molding mold cavity. The die casting mold of the water-cooled double-clutch shell has the following advantages: because of using multiple side pressing mechanisms and combining with oil cylinder driven valve vacuumizing, the shrinkage phenomenon on the surface of a casting is prevented, and the overall quality of the clutch shell is guaranteed; and in addition, the cooling problem of thinner edge circular grooves in the clutch shell is solved through the water cooling runner device, so that the peripheral surfaces of the edge circular grooves are cooled, the cooling effect is good, and the overall quality of the clutch shell is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of die-casting molds, in particular to a water-cooled dual-clutch housing die-casting mold. Background technique [0002] In the domestic die-casting field, air cooling is mostly used for mold cooling. With the development of cooling technology, natural room temperature full water cooling has become a new cooling method for die-casting molds. However, in this method, the mold inlet water temperature is not constant, and the cooling effect is unstable. If the temperature deviation is large, it is easy to produce shrinkage, shrinkage and cavities. Operators often rely on experience to estimate and set cooling time and other parameters within the scope of the instruction book, which is not conducive to stable casting process, not conducive to efficient production, and affects output and quality. such as production figure 1 with figure 2 Zhongde clutch housing 3 products, here in the thermoforming process, be...

Problems solved by technology

[0002] In the domestic die-casting field, air cooling is mostly used for mold cooling. With the development of cooling technology, natural room temperature full water cooling has become a new cooling method for die-casting molds. However, in this method, the mold inlet water temperature is not constant, and the cooling effect is unstable. If the temperature deviation is large, shrinkage and shrinkage cavities are prone to occur. Operators often rely on experience within the scope of the instruction book to estimate and set parameters such as cooling time, which is not conducive to stabilizing the casting process, is not conducive to efficient production, and affects output and quality.

such as production figure 1 and figure 2 Zhongde clutch housing 3 products, here in the thermoforming process, because there are many irregular raised positions 4 around the outer surface of the clutch, if the die-casting process is not controlled, the raised structures will be formed Partial shrinkage cavity and shrinkage porosity directly reduce the strength of the casting, water leakage and air leakage in the pressure test of the casting, and cavities appear on the machined surface, resulting in unqualified castings. At the same time, there is an inner large round hole on the clutch housing 3, here in the inner large round hole It has a thinner edge round groove 34, which requires a ring of highly raised inserts during molding. Here, the edge round groove is located on the inner side and cannot be cooled well due to the setting of its own structure, which is prone to high temperature sticking. Therefore, the finished product after casting is prone to cracking and deformation, and the overall quality and performance of the clutch housing will be reduced in the subsequent process.
