Mold frame mechanism for high-precision powder mold forming servo press

Abstract

The invention discloses a mold frame mechanism for a high-precision powder mold forming servo press. The mechanism comprises a master pattern, an upper sliding assembly, a lower sliding assembly, a fixed mold mounting plate, a mold mounting plate, a middle bar base and core bars. A lower mold base is arranged above the fixed mold mounting plate, a gap is reserved between the lower mold base and the fixed mold mounting plate, a lower mold is arranged on the lower mold base, the middle bar base is arranged in the gap between the lower mold base and the fixed mold mounting plate, a mold mountingplate is arranged above the lower mold base, the master pattern is arranged on the mold mounting plate, the middle bar base and the master pattern are fixedly connected, multiple mold cavities in clearance fit with the lower mold are machined in the master pattern, multiple core bars penetrating through the lower mold are arranged on the middle bar base, and the tops of the core bars are arrangedin the mold cavities. The master pattern, the upper mold, the lower mold and the core bars are arranged on the mold mounting plate, the upper mold, the lower mold and the core bars are matched with the master pattern, the filling powder can be conveniently pressed into a cylindrical product with the inner ring and the outer ring concentric, and meanwhile, the equipment pressing precision is ensured.

Description

technical field [0001] The invention relates to the field of powder processing mold bases, in particular to a mold base mechanism for a high-precision powder molding servo press. Background technique [0002] Powder metallurgy is the process and technology of manufacturing metal powder and using metal powder as the basic raw material to manufacture metal materials and special-shaped products. In powder metallurgy, compression molding is the most important and widely used forming method. Compression molding is to put metal powder or powder mixture into a steel die, pressurize the powder through die punching, and after the pressure is released, the compact is released from the die to complete the molding process. The formwork is an essential process equipment for manufacturing powder metallurgy products. [0003] The existing equipment used to press and fill powder is a powder molding machine, but the mold base used in the existing powder molding machine is to fix the middle...

Problems solved by technology

However, due to the floating connection between the existing mother mold and the upper mold and the lower mold, it is easy to cause the upper mold and the lower mold to be difficult to accurately align the position on the mother mold, and it is easy to cause damage to the mold. In addition, because the upper mold and the lower mold Floating connection with the mother mold, so the deviation generated when the upper mold and the lower mold move will cause uneven force on the pressed product, and it is difficult to grasp the contact position of the upper mold and the lower mold with the mother mold. The mold needs to be debugged repeatedly by professional technicians, resulting in cumbersome installation process

In addition, the existing upper mold and lower mold both provide power to move up and down through the rocker arm, which is likely to cause unstable powder filling in the mother mold and poor precision of the pressed product.
