Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sealing ring production, more specifically, it relates to an extrusion positioning mechanism for sealing ring production. BACKGROUND

[0002] In the traditional sealing ring production process, due to the inaccuracy of the cooperation between the mold assembly and the positioning mechanism, or the uneven pressure distribution of the positioning mechanism, the mold is prone to tilting during the pressing process. Specifically, the positioning of the mold is not stable enough, and may deviate or be misaligned during pressing, which not only affects the dimensional accuracy of the sealing ring, but also may cause mold damage or low production efficiency. For example, if the pressing force of the mold is uneven, some areas may be subjected to excessive pressure, while other areas are subjected to insufficient pressure, further increasing the risk of tilting.

[0003] Traditional pressing positioning mechanisms usually adopt a fixed design. Once the mold is installed, the pressing force and position need to be adjusted manually according to production requirements. However, this adjustment process is often tedious and cannot quickly adapt to the needs of different molds. For example, some molds require a larger pressing force, while others may require a smaller pressing force. Traditional equipment usually requires manual replacement or adjustment of multiple mechanical components to complete this adjustment, increasing the complexity of operation and time cost.

[0004] Because the adjustment mechanism of traditional equipment is often limited to a fixed adjustment range, it cannot adapt to various molds of different sizes and types. There are many types of molds, some of which are complex in design and irregular in shape, or require more detailed adjustment. However, existing positioning mechanisms often lack flexibility and cannot adapt to different mold requirements in a short time. This problem is particularly evident when molds are frequently replaced during the production process. The equipment cannot be accurately adjusted in time, affecting the pressing and positioning accuracy of the mold, and thus affecting the production quality of the sealing ring. SUMMARY
