In this embodiment, the end frame body 1 includes two uprights 11 and locates the crossbeam between the uprights, and long beam seat 21 locates the side of upright 11 and leans on the back position, and end frame body 1 forms the die carrier of stair through connecting long beam 2, can install stair and/or elevator in the die carrier. The cross-sectional shapes of the two upright columns 11 are both rectangular channel steel structures, and the two upright columns are the same in size. The notches of the two upright posts 11 are arranged oppositely, the upper end and the lower end of the notch side are respectively connected with an upper cross beam 12 and a lower cross beam 13, the upper cross beam 12 and the lower cross beam 13 are of channel steel structures, the height of the upper cross beam 12 is larger than that of the lower cross beam 13, and an air inlet and an air outlet and the like can be arranged on the upper cross beam 12. In the present embodiment, the sectional shape of each of the columns 11 is rectangular, and the weight of the end frame body 1 can be reduced compared to a case where the sectional shape of one column is rectangular with a square or larger size.

In this embodiment, the upper and lower both ends lateral part of stand 11 all is equipped with long beam seat 21, and the side of stand 11 is equipped with connecting plate 3, is equipped with a plurality of screw holes on the connecting plate 3, and wherein long beam seat 21 carries out bolted connection with some screw holes of connecting plate 3, and another part screw hole is used for connecting the fly-beam, and the fly-beam outwards extends along the width direction of stair die carrier for the stair die carrier can be connected with another stair die carrier through the fly-beam, forms composite formwork. In addition, in the embodiment, the notches of the two upright columns 11 are arranged oppositely, so that bolts can be screwed conveniently from the notch side, and the connection between the upright columns 11 and the long beam seat 21 and the connection between the upright columns 11 and the movable beam are realized. This embodiment is through setting up long roof beam seat 21, on the one hand, can increase the interval between the adjacent long roof beam, and then increases the inner space of die carrier, is convenient for install the stair in the die carrier, satisfies the mounting dimension requirement of stair.

In this embodiment, the long beam 2 is also of a channel steel structure, and the long beam 2 and the rear end surface of the long beam base 21 are fixed by bolts or welding at positions close to the outer sides. The distance between the two long beams 2 at the upper part of the mould frame or the distance between the two long beams at the lower part of the mould frame is larger than the width of the end frame body 1, so that the installation requirement of the stairs is met.

In this embodiment, the upper end and the lower extreme of stand 11 all are equipped with flange plate 4, interconnect between the stand 11 of the die carrier about being convenient for, form multilayer stair die carrier. Wherein the long beam seat 21 is flush with the top surface of the flange plate 4.

In this embodiment, the front sides of the upper and lower ends of the upright post 11 are detachably connected with corner fittings 5. The corner fitting 5 comprises a corner fitting body 51 and a corner fitting seat 52, a mounting seat is arranged on the upright post 11, one end of the mounting seat is arranged close to the flange plate 4, and the corner fitting body 51 is in threaded connection with the mounting seat on the upright post 11 through the corner fitting seat 52. The corner fitting body 51 comprises a hoisting hole 511, a side hole 512 and an end hole 513, and the external dimension of the corner fitting body 51 conforms to the standard dimension of an international container so as to facilitate sea and land transportation. The corner fitting seat 52 is disposed on the other side opposite to the side hole 512, and is welded to the corner fitting body 51. One surface of the corner fitting seat 52 is provided with an opening 521, and the other surface opposite to the opening is provided with a connecting part. The connecting portion includes a plurality of screw holes, and by providing the opening 521, a bolt can be screwed in from the opening side to fix the corner fitting seat 52 to the mounting seat of the pillar 11. The corner fittings 5 are integrally arranged outside the end faces of the upright posts 11, extend outwards along the upright posts 11, for example, the corner fittings on the left upright post extend leftwards, and the corner fittings on the right upright post extend rightwards, so that the positions of the corner fittings accord with the container transportation standard. The corner fitting of the present embodiment has the following advantages: (1) The corner fitting body is connected to the upright post through the corner fitting seat, so that the corner fitting body does not need to be accurately positioned, and the corner fitting body does not need to be subjected to finish machining, so that the machining difficulty and the machining cost are reduced; (2) Need not to set up the breach on the stand and come the embedding corner fittings, only need through the corner fittings seat connect can, simplify the structure greatly, in addition because the stand need not to open and lack, so thinner that the thickness of cylinder can be done alleviates cylinder weight greatly, and the thickness of crossbeam also can further reduce to reduce the weight of end frame body, and then reduce the weight of whole die carrier.

In summary, on the one hand, the internal space of the mold frame can be increased on the basis of ensuring the small size of the end frame body, so that the requirement of the installation size of the stair is met; on the other hand, the weight of the end frame body is reduced, and the weight of the whole die frame is further reduced; and the upright posts do not need to be provided with the corner fittings, so that the structure is greatly simplified.
