Abstract

The invention belongs to the technical field of a die-casting die and provides a vacuum pumping side-pressing mechanism for manufacturing a water-cooled clutch casing. The vacuum pumping side-pressing mechanism is arranged on the side edge of the die-casting die; the clutch casing is arranged in an injection die cavity of the die-casting die; three the vacuum pumping side-pressing mechanisms are adopted and are propped against bulge positions of the clutch casing in the injection die cavity, each vacuum pumping side-pressing mechanism comprises a valve type vacuum pumping device and a side-pressing device, the valve type vacuum pumping device communicates with the injection die cavity and is used for performing vacuum pumping actions, and the side-pressing device is linked with the valve type vacuum pumping device and used for extruding the corresponding bulge position of the clutch casing, so that the bulge position performs feeding after being subjected to extrusion pressure. The vacuum pumping side-pressing mechanism has the advantages as follows: the multiple side-pressing mechanisms are adopted and combined with the oil cylinder driven valve type vacuum pumping, so that phenomena of shrinkage cavity and shrinkage porosity in the surface of a casting are avoided, and the overall quality of the clutch casing is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of die-casting molds, in particular to a vacuum side pressure mechanism for manufacturing water-cooled clutch housings. 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 Zhongde clutch housing 3 products, here in the thermoforming...
