Technical Field
The invention relates to the technical field of capsule molds, and particularly discloses a negative pressure-proof capsule mold capable of preventing powder leakage.
Background
The hollow capsule comprises a capsule shell and a capsule cap which are both formed by a mould. The production process in the current market is roughly divided into the processes of sol, glue dipping, drying, demoulding, notching and the like. The glue dipping process specifically comprises the steps of placing the mould into glue solution for dipping once, taking out, drying and demoulding to obtain the capsule shell and the capsule cap.
In the process of producing related medicine capsule granules the medicinal powder is filled into the capsule shell, the capsule cap is covered, and then the capsule shell and capsule cap are tightly connected by means of ring grooves on them. At present, the capsule particles produced by using the existing capsule mould pack medicinal powder into the prepared medicinal capsule without problems in normal environment, but in some regions with higher altitude, the air is thin so that the inside and the outside of the capsule have larger air pressure difference, thereby the capsule shell and the capsule cap which are clamped through the annular groove are slipped, and the medicinal powder inside the capsule shell is leaked.
For example, utility model application No. 2010201649539 discloses just an empty capsule mould body, is cylindrically, and its head is the hemisphere, is provided with the ring channel on being close to the outer face of cylinder of mould body head, still is provided with a plurality of recesses on the outer face of cylinder between mould body bottom and the ring channel, this a plurality of recess circumferential clearance distribution. The utility model discloses a capsule mould is the most common on the existing market promptly, can be fixed with the bag shell and the bag cap joint that generate out through the ring channel that sets up set up at the mould body head, but the bag shell and the bag cap that this capsule mould produced can't realize the lock behind the joint and die, and consequently the medicine capsule of preparation when highland area, appears the above-mentioned because inside and outside air pressure difference leads to the condition of bag shell and bag cap slippage easily. Therefore, aiming at the defect that the medicine capsule produced by the existing capsule mould can not be stably stored in a high altitude area, the technical problem to be solved is to design the powder leakage prevention and negative pressure prevention capsule mould which can solve the technical problem.
