Spliced stamping mould

Abstract

The invention discloses a spliced stamping mould. The mould comprises an upper mould component and a lower mould component, wherein the lower mould component comprises a lower mould seat, a material supporting block and at least two splicable lower mould splicing blocks which encircle the outer side of the material supporting block and are connected to the lower mould seat in a sliding mode; the material supporting block has a liftable structure; inner side surfaces encircled by splicing the lower mould splicing blocks and the top surface of the material supporting block can be spliced to form a complete lower mould surface; the upper mould component comprises an upper mould seat, an upper mould and push blocks; the upper mould is fixedly arranged on the bottom surface of the upper mould seat; and the push blocks encircle the outer side of the upper mould, correspond to the lower mould splicing blocks one to one and are used for pushing the corresponding lower mould splicing blocks for splicing when a workbench on a stamping machine descends. The lower mould of the spliced stamping mould has a spliced structure, each lower mould splicing block can move to the outer side to be separated from a workpiece along the horizontal direction after stamping forming, the workpiece is supported by the material supporting block, the top surface of the material supporting block is a part of lower mould surface, and the contact area of the material supporting block and the workpiece is relatively small, so that the workpiece with a complex surface structure is easy to take out, material blocking can be effectively avoided, and production efficiency can be ensured.

Description

technical field [0001] The invention relates to a stamping die, in particular to a split stamping die. Background technique [0002] When the stamping process is carried out on the press, the workpiece is often stuck on the lower die and is not easy to take out, which affects the continuity of production and the production efficiency is low. Material rod, elastic ejector device, etc., in order to take out the workpiece from the lower mold, but the impact type punching rod will exert an impact force on the workpiece, which will not only cause damage to the workpiece, but also cause the workpiece to be disordered under the action of the impact force. The pop-up and scattered, the scene is chaotic, there are certain safety hazards, which is not conducive to automatic production; when using the elastic lifting device, it is usually set as a spring or elastic rubber to provide elastic force, the elastic force is related to the deformation, and the elastic force is a variable forc...

[0002] When the stamping process is carried out on the press, the workpiece is often stuck on the lower die and is not easy to take out, which affects the continuity of production and the production efficiency is low. Material rod, elastic ejector device, etc., in order to take out the workpiece from the lower mold, but the impact type punching rod will exert an impact force on the workpiece, which will not only cause damage to the workpiece, but also cause the workpiece to be disordered under the action of the impact force. The pop-up and scattered, the scene is chaotic, there are certain safety hazards, which is not conducive to automatic production; when using the elastic lifting device, it is usually set as a spring or elastic rubber to provide elastic force, the elastic force is related to the deformation, and the elastic force is a variable force , the performance will decrease after long-term use, and the elastic elements need to be replaced regularly, which is costly and is only used to provide elastic ejection force, which cannot guarantee that the workpiece will be ejected as required under the action of the ejection force. For workpieces with complex surface structures, the ejector The material function cannot be guaranteed, and the problem of material jams cannot be avoided. Once a material jam occurs, the continuous elastic force will obliquely jam the workpiece into the mold, making it more difficult to take out the workpiece, and even damage the mold surface.
