The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art in a specific case.

As shown in fig. 1 to 3, the present utility model provides a combined mold for bridge molding, which includes a male mold 100 and a female mold 200 having equal lengths;

The male die 100 includes two male die ends 110 and a plurality of male modules 120, and the plurality of male modules 120 are disposed between the two male die ends 110;

The master model 200 includes two master model end portions 210 and a plurality of master model blocks 220, wherein the plurality of master model blocks 220 are arranged between the two master model end portions 210. By changing the number of the male mold pieces 120 and the female mold pieces 220, the length of the entire mold can be changed to correspondingly produce the bridges of different specifications, further, the male mold end 110 and the female mold end 210 can also be replaced, the male mold end 110 and the female mold end 210 correspondingly form the sides of the bridge, and when the bridges with different side heights are required to be produced, the male mold end 110 and the female mold end 210 with different lengths can be replaced.

Further, the male module 120 includes three specifications, and the width ratio of the male module 120 of the three specifications is 1:2:5; it is easy to know that according to the proportion, any length of splicing can be realized through the modules with three different specifications, and the proportion of 1:2:5 refers to the proportion of 1 yuan, 2 yuan and 5 yuan of the old renminbi, so that any number below 10 and 10 can be formed by the combination of the most reasonable quantity.

The female mold piece 220 has the same specification as the male mold piece 120, and the male mold 100 and the female mold 200 having the same specification can be assembled.

Further, the male end 110 and the female end 210 are used to form longitudinal ribs 310 on the side walls of the bridge 300; as shown in fig. 4, the longitudinal ribs 310 are square, but may be longitudinal bar-shaped ribs along the bridge direction, which serve to enhance the bending resistance of the bridge.

The male module 120 and the female module 220 are used to form transverse ribs 320 at the bottom of the bridge 300. As shown in fig. 4, the direction of the transverse reinforcing ribs 320 is perpendicular to the length direction of the bridge 300 itself, so as to enhance the deformation resistance of the bottom of the bridge.

Further, the male mold end 110 has a forming portion 111 at an end of the transverse reinforcing rib 320 at a position close to the male mold 120. As shown in fig. 2, the male and female mold pieces 120 and 220 have no end portion corresponding to the molding portion of the lateral reinforcing rib 320, so that the male and female mold pieces 120 and 220 can be spliced in any order.

Further, the female module 220 includes a moving block 221 and a core 222, and the moving block 221 moves on the core 222 in a direction approaching or moving away from the male module 120.

Further, a pin 223 and a spring 224 are disposed between the movable block 221 and the core 222, the spring 224 is sleeved on the pin 223, the pin 223 is inserted into the movable block 221, and the movable block 221 moves along the pin 223. By arranging the movable block 221 and the core 222, pre-compression of the plate before forming is realized, and the problem of plate deflection in the forming process is reduced.

During operation, the male mold 100 and the female mold 200 move in opposite directions to clamp a flat plate, specifically, the flat part on the male mold 100 and the movable block 221 of the female mold 200 clamp the plate, then further move in opposite directions, the movable block 221 overcomes the elastic force of the spring 224 to move, and the core 222 protrudes out of the surface of the movable block 221 and is matched with the molding part on the male mold 120, so that the deep drawing process and the molding of the reinforcing ribs are realized.

The present utility model is not limited to the above-mentioned embodiments, but is intended to be limited to the following embodiments, and any modifications, equivalent changes and variations in the above-mentioned embodiments can be made by those skilled in the art without departing from the scope of the present utility model.
