Titanium alloy metal injection molding automotive compression valve seat MIM parts

The compression valve seat in an automobile shock absorber has a mounting surface for mounting a compensation valve plate. The compression valve seat is characterized in that a number of limit blocks are provided on the mounting surface, and the limit blocks protrude to the outside of the mounting surface. , these limit blocks are arranged on the mounting surface at intervals along the circumferential direction of the mounting surface. The limit block protrudes to the outside of the installation surface of the compression valve seat. When the compensation valve plate is placed on the installation surface, the limit block is used to limit the position of the compensation valve plate on the compression valve seat. The ring formed by the inner ends of these limit blocks should be slightly larger than the outer circle of the compensation valve plate, so that the compensation valve plate can be placed in the middle of these limit blocks. After the compensation valve plate is accurately placed on the mounting surface, the compensation valve plate and the compression valve seat need to be fixed with fastening screws.

Preferably, the center line of the limiting block is located in the radial direction of the mounting surface. This facilitates the setting of the position of the limiting block on the mounting surface.

Preferably, the outer edge of the limiting block intersects the outer peripheral surface of the compression valve seat. The outer end of the limiting block extends to the outer peripheral surface of the compression valve seat, thereby facilitating the processing of the casting mold for producing the compression valve seat and also facilitating the demoulding of the mold.

Preferably, the inner end and outer edge of the limiting block are provided with chamfered surfaces. The chamfered surface makes it easy to place the compensation valve plate in the middle of these limit blocks.

Preferably, the inner end surface of the limiting block is an inclined surface, and the inclined surface is inclined toward the radially outer side of the mounting surface. The inner end surface of the limit blocks is a bevel, which is also to facilitate the placement of the compensation valve plate in the middle of these limit blocks.

Compared with the existing technology, the beneficial effects of this utility model are reflected in:

Since the several limit blocks are provided on the installation surface of the compression valve seat, and the limit blocks protrude to the outside of the installation surface, it is convenient to place the compensation valve plate on the installation surface, and the compensation valve plate is placed on the installation surface. After installation, the position accuracy of the compensation valve plate on the installation surface is good, making it easy to install the compensation valve plate on the installation surface, and the operation efficiency is high.
