Description

Universal die carrier Technical Field The invention relates to the technical field of die bodies, in particular to a universal die carrier. Background In the current industrial production, the die carrier is used as a base frame of a die, and is widely applied to forming processes such as stamping, injection molding, die casting and the like. Conventional mold frame designs are typically custom made for a particular product or particular specification of mold, i.e., a set of mold frames can only accommodate one or more fixed size mold cores. In the prior art, the stamping die carrier comprises a stamping table, a lower die carrier arranged in the stamping table, an upper die carrier arranged at the top of the lower die carrier, a clamping assembly arranged in the lower die carrier and used for clamping and fixing a workpiece, and a buffer assembly arranged between the lower die carrier and the stamping table and used for reducing impact force generated on the lower die carrier. This kind of resistant punching press die carrier can be fixed to work piece both ends centre gripping through the centre gripping subassembly, further consolidates the work piece and places, prevents that the work piece from becoming flexible skew, avoids the work piece punching press to warp to produce elastic deformation's effort through buffer unit and cut down impact force, avoid taking place violently striking between die carrier and the lower die carrier to the maximum degree and cause the damage, ensure the safety in production of punching press die carrier. The special design causes a plurality of problems that firstly, when the design of the product is changed or products with different specifications are required to be produced, the whole die carrier is required to be redesigned and manufactured, so that the development period of the die is long and the cost is high. Secondly, for a production enterprise, a large number of die frames with different specifications are required to be reserved for different products, so that huge storage space is occupied, funds and materials are wasted, and furthermore, the positions of structures such as a guide post, a guide sleeve and a mounting groove of the traditional die frame are fixed, flexible adjustment cannot be performed according to the change of the die core size, the universality is extremely poor, and the requirements of small-batch and multi-variety modern flexible production are difficult to adapt. Therefore, a general die carrier structure which can adapt to die cores with different sizes, is convenient to adjust and can be reused is needed in the market, so that the development cost of the die is reduced, and the production efficiency and the resource utilization rate are improved. Disclosure of Invention The present invention is directed to a universal mold frame, which solves the problems set forth in the background art.
