AI Technical Summary

Technical Problem

Existing technologies make it difficult to achieve human-machine isolation during the pressing of pharmaceutical columns, failing to meet the requirements of inherently safe production, and have low mold closing accuracy, resulting in flash problems.

Method used

The split conical locking compression mold is used, including an extrusion assembly and a mold assembly. The locking conical sleeve and the core positioning seat are used to achieve the alignment of the core and the mold cavity. Combined with the conical surface locking structure, it achieves high mold closing accuracy and no flash, and isolates people from hazardous materials.

Benefits of technology

It achieves human-machine isolation, improves the quality of compressed medicine, meets the requirements of inherently safe production, has high mold closing accuracy and no flash, and simplifies the mold structure.
