AI Technical Summary
Technical Problem
In existing hard capsule ejection molds, the cylindrical capsule comes into contact with the mold hole surface during capsule ejection. The large contact area makes it easy to scratch the outer wall of the capsule, resulting in wear and cracking of the capsule surface.
Method used
Design a scratch-resistant ejection mold for hard capsules. Employ polygonal mold holes and anti-friction coating to reduce the contact area between the capsule and the mold holes. Use line contact to reduce friction. Adapt to different shape requirements through a replaceable mold hole plate structure.
Benefits of technology
Reduce dragging damage during capsule ejection, protect the capsule surface from scratches or cracks, and ensure the airtightness of the drug packaging.

Abstract
The utility model relates to hard capsule discharge mould technical field, especially a kind of hard capsule scratchproof discharge mould, including mould main body, capsule forming area and positioning hole, the inside of capsule forming area is movably connected with multiple capsule bodies, the outside of capsule body is equipped with hard capsule scratchproof structure, the inside of mould forming area is equipped with discharge mould hole plate replacement structure.This hard capsule scratchproof discharge mould, when capsule is taken out, its outer wall only forms line contact with the edge part of polygonal die hole, the reduction of contact area directly leads to the decline of friction between capsule and die hole, reduces discharge resistance, reduces the drag injury of capsule in the process of taking out, simultaneously line contact makes stress concentrate on edge, rather than large-area sticking, even if there is tiny flaw in die hole inner wall, only local line contact with capsule surface is formed, not easy to cause large-area scratch or cracking, especially protect the locking position of capsule cap and capsule body, avoid the influence of subsequent drug packaging sealing due to scratch.
