Sealed laminated slab combined die

The invention discloses a sealed laminated slab combination die. The sealed laminated slab combination die comprises two first lower standard sections and two first upper standard sections, wherein the first lower standard sections are located at the bottoms of the first upper standard sections, the two first lower standard sections and the two first upper standard sections are distributed front and back, the two sides of the first lower standard section are fixedly connected to the second lower standard sections, the sides, away from the next standard sections, of the second lower standard sections are fixedly connected to lower connecting corner parts, and the longitudinally corresponding sides of the two lower connecting corner parts are fixedly connected to lower non-standard sections. According to the sealed laminated slab combined die, the combined die has the characteristic of recombining and recycling, and meanwhile, has the characteristic of effectively solving the problem of die sealing without cons
