Description

Mould Technical Field The invention relates to the field of rubber molds, in particular to a mold. Background With the continuous development of the power equipment manufacturing industry, the specific requirement of the rubber box edge sealing member structure on the market is caused, and the polygonal special box edge is gradually derived from the initial rectangular box edge. In common production practice, a special die is adopted to integrally mold and form a sealing piece product of the rubber box edge, and the rubber box edge sealing piece product is required to be designed and manufactured according to the size of the product and is installed on large-scale rubber vulcanization equipment for use, so that the rubber box edge sealing piece is large in size, difficult to carry, high in manufacturing cost and high in equipment energy consumption. And due to the limitation of the mould and equipment, the polygonal special-shaped box edge sealing piece product cannot be produced. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide a die for solving the problem that the prior die cannot produce polygonal special-shaped box edge sealing piece products. The die comprises an upper die main body, an insert assembly and a lower die main body, wherein the insert assembly at least comprises a bending insert, the lower die main body comprises a bottom die and two side blocking parts positioned on two opposite sides of the bottom die, the bending insert is detachably connected to the bottom die and positioned between the two side blocking parts, and the side blocking parts are fixedly connected with the bending insert. Preferably, an upper limit rib is arranged on the bottom die, two ends of the upper limit rib are respectively connected with two side blocking parts, the upper limit rib and the two side blocking parts form a semi-closed inner cavity on the bottom die, and the bending insert is positioned in the inner cavity. Preferably, the bending insert comprises a first connecting part and a second connecting part, and one end of the first connecting part is fixedly connected with one end of the second connecting part to form the bending insert with a bending angle. Preferably, the first connecting part is provided with a first cavity, the second connecting part is provided with a second cavity, and the first cavity and the second cavity are communicated at the bending angle. During production, the sizing material is placed in the die cavity. Preferably, the bottom die is further provided with a first chute, the first chute is located below the upper limit rib, the first connecting portion is provided with a first through hole, and the first through hole is correspondingly matched with the first chute and then is penetrated by a fastener. The first through hole can be fixedly connected to any position of the first chute, so that the bending insert is detachably connected to the lower die main body. Preferably, the bottom die is also provided with a second chute, the second chute is positioned below the first chute, the second connecting part is provided with a second through hole, and the second through hole is correspondingly matched with the second chute and then is penetrated by a fastener.
