Introduction
The mold casting of the inclined sliding block guide parts is an important part of the casting process. In most cases, the quality, accuracy and efficiency of production will be greatly improved by selecting and controlling the parameters of die casting. For the inclined sliding block guide parts, the parameters of die casting need to be carefully selected and controlled, which will lay a solid foundation for the quality improvement, accuracy improvement and efficiency improvement of the casting process.
Design and Manufacturing of Molds
Molds for the inclined sliding block guide parts are mainly composed of female molds and male molds. Before injection molding, it is necessary to carry out mold design. During the mold design process, the parameters of design must be confirmed, including the size of template, the form and configuration of parting surface, the form and configuration of guide post and inclined block, cooling system, and other related parameters. After the mold design is completed and the molds have been made, the casting parameters should be adjusted according to the shape, size and quality requirements of the parts.
Preparations for Casting
Before the melting and injection process, a series of casting preparation works must be done. Firstly, the molten metal should be melted in a casting furnace, and the temperature and chemical composition of the molten metal must be carefully controlled, otherwise the surface quality, dimensional accuracy and mechanical properties of the parts will be greatly affected. Secondly, the mold must be heated, if necessary, and the temperature should be adjusted according to the composition and structure of the molten metal. Since the operating temperature of the mold will be close to the operating temperature of the molten metal, the temperature difference between the two must remain within a certain range. Thirdly, it is necessary to determine the injection parameters and pressure of the molten metal, so as to ensure that the molten metal can completely fill the cavity of the mold.
Parameters of Die Casting for Inclined Sliding Block Guide Parts
The parameters of die casting for the inclined sliding block guide parts include the injection pressure, the injection speed, the holding pressure and the holding time. The injection pressure, injection speed and holding pressure of the inclined sliding block guide parts should be determined according to the plasticity, temperature and viscosity of the molten metal, the structure, size and accuracy of the parts, and the distribution and cooling efficiency of the molten metal in the cavity of the mold. The holding time should be determined according to the size, wall thickness and shape of the parts.
The injection pressure and injection speed of the inclined sliding block guide parts must be reasonably determined. The injection pressure should be determined according to the structural shape, size and accuracy requirements of the parts. Generally, the injection pressure should be increased when the structural shape of the parts is complicated, while it should be reduced when the size and accuracy requirements of the parts are high. The injection speed should be determined according to the plasticity and temperature of the molten metal. Generally, the injection speed should be increased when the plasticity and temperature of the molten metal are high.
Conclusion
The parameters of die casting for the inclined sliding block guide parts play an important role in improving the quality, accuracy and efficiency of the casting process. Therefore, the selection and control of the parameters of die casting must be carefully carried out, which will lay a solid foundation for the quality improvement, accuracy improvement and efficiency improvement of the casting process.
