一种具有更换功能且自动脱模的冲压模具
摘要：
本发明涉及冲压模具脱模领域，具体为一种具有更换功能且自动脱模的冲压模具，包括工作台、悬架、液压缸、上模、下模；所述下模与工作台之间通过螺纹连接；所述下模内部设置有脱模装置，所述脱模装置包括沿着下模内部竖直方向运动的顶板、弹簧以及承载板。本发明通过设置可拆卸式的下模，以及在下模内部设置可更换式的弹簧；解决了现有当弹簧损坏不能提供弹力时，零件就无法取出，再加上弹簧不能更换，所以整套模具就会被丢弃，造成资源的浪费以及增加生产成本的问题；另外本发明易于操作和维护维修，结构简单，成本较低。
摘要（英）：

The invention relates to the field of stamping mold demolding, in particular to a stamping mold with functions of replacement and automatic demolding. The stamping mold comprises a workbench, a suspension frame, a hydraulic cylinder, an upper mold and a lower mold; the lower mold is connected with the workbench through threads; and a demolding device is arranged inside the lower mold, the demolding device comprises a top plate, springs and a bearing plate, wherein the top plate, the springs and the bearing plate move in the vertical direction in the lower mold. According to the stamping mold,the detachable lower mold is arranged, and the replaceable springs are arranged in the lower mold, so that the problems that when the springs are damaged and cannot provide elasticity, a part cannot be taken out, in addition, the springs cannot be replaced so that the whole mold can be abandoned, then the waste of resources is caused, and the production cost is increased are solved; and in addition, the stamping mold is easy to operate, maintain and repair, and is simple in structure and low in cost.
