The utility model relates to a small plunger type press forming die, which belongs to the field of die design. The inner cavity of the medicine cylinder is a cylindrical cavity, the bottom of the medicine cylinder is supported by a chassis seat, the medicine mold is installed at the bottom of the medicine cylinder inner cavity, the lining sleeve is installed above the medicine cylinder inner cavity mould, and the medicine mold is axially limited in the medicine cylinder inner cavity by screw inserting the pressure ring at the upper end of the medicine cylinder. The upper and lower ends of the jacket shell are respectively machined with water inlets and outlets; the front end of the punch is a cylindrical pressing section whose outer diameter matches the inner diameter of the lining sleeve, and the back end of the punch is sleeved with a circular tray. The press-stretch forming die of the utility model can simulate the discharge pressure of the screw press-stretch machine, grasp the discharge pressure and speed of the medicine in advance, guide the press-stretch, and reduce the safety risk of the press-stretch. At the same time, a small amount of chemicals can be used to stretch the physical and chemical properties of the samples.
【技术实现步骤摘要】
一种小型柱塞式压伸成型模具
本技术涉及一种小型柱塞式压伸成型模具,属于模具设计领域。
技术介绍
在固体推进剂装药的科研、生产过程中,由于一些条件限制,诸如设备昂贵,模具中需充填较多的无效药料,故高风险药料不能直接螺旋压伸、压制少量的含稀有原材料的药不经济、部分药料在螺旋压伸过程中负荷高导致无法压制。而柱塞式压伸成型机可弥补上述不足。其中柱塞式压伸成型模具的压缩比、料面的深径比经特定设计,可压制出符合要求的药柱,从而可以弥补螺旋压伸的不足。同时可模拟螺旋压伸过程中药料在模具中的出药压力,降低螺旋压伸试验风险。在科研生产过程中,起到不可或缺的作用,对新产品的研发有指导意义。
