The die body of the tablet press belongs to the field of tablet press. The utility model is characterized in that the punching tail and the punching body are integrated, the punching cover is fixed with the punching body through a pin, and the punching nail is fixed on the punching cover. The integral structure of the conventional mold was changed to the separate structure. The requirement of the mold precision can be guaranteed by the analysis of the use angle. In the production process, the wear of the mold usually appears in the part of the punch pin. The split mold can be achieved. When the punch pin is worn, only the part of the punch pin can be replaced separately, and the operation is very simple (only the location pin can be disassembled and assembled). The price of each punching nail is about 30 yuan RMB, which is only one third of the cost of the conventional mold. It greatly reduces the economic pressure of the customers in replacing the mold and reduces the running cost. The utility model has the advantage that a die with a split structure does not need to be replaced as a whole after wearing, but only needs to replace the punching nail part, thus greatly reducing the operation cost of the user.

压片机分体模具
本技术属于压片机领域。
技术介绍
压片机是将干性颗粒状或粉状物料通过模具压制成片剂的机械设备，所以模具在压片机完成片剂压制的过程中，作用非常重要。然而片剂压制过程中，受物料颗粒摩擦的影响，受压片力而产生出片阻力大小的影响，模具或多或少的存在磨损，尤其是上下冲杆的冲钉部分和中冲模的片形孔，直接导致模具的使用寿命。因模具的磨损，会导致药片质量下降，所以定期必须更换模具。模具在压片生产中的磨损程度是与物料颗粒情况密不可分，某些物料成分硬度很高(例如中药的矿物类成分-牛黄、矿石、贝壳类等)，对于模具的磨损就会加剧；而因为物料的可压性影响，某些品种为了保证硬度或崩解时限，压片力就必须加大，随着压片力的增加，出片力也随之增加，药片成型后在出片环节对于中模片形孔的磨损就会加剧；所以某些品种压片生产中，模具的损耗较大，必须及时更换。压片机模具的寿命一般在正常情况下，每付可以达到几百万次，甚至上千万次，而遇到某些特殊品种时，模具寿命会减少到几十万次，甚至更少。无形中，增加药企购置模具的费用，运行成本增加，药企急需解决模具寿命问题，或者降低模具费用，减少运行成本。专利...
