As a specific way of realizing the up-and-down adjustment of the upper end die, at least one of the connecting hole and the positioning hole is a long round hole.

In order to reduce the slurry leakage amount, a sliding groove is arranged on the inner wall of the waist plate of the upper end die corresponding to the U-shaped groove, a sliding block capable of sliding along the length direction of the groove is arranged in the sliding groove, and a limiting table is arranged at the bottom end of the sliding groove.

Furthermore, the sliding block comprises a T-shaped sliding rod and a plugging plate, and the plugging plate is an arc plate which is arranged downwards.

Preferably, a limiting hole for the T-shaped sliding rod to penetrate through is formed in the middle of the limiting table.

When the utility model is used, the two side molds are placed on the mold table in parallel, then a pair of lower end molds are respectively placed at the two ends of the two side molds, then the upper end mold is placed on the lower end mold, and the upper end mold and the side molds are locked to compress the lower end mold, so that the upper end mold, the lower end mold and the side molds form a molding cavity on the mold table; the U-shaped groove of the lower end die is used as a rib passing groove for bearing the embedded steel bars, so that the positioning is facilitated, the area of the rib passing groove can be effectively reduced, and the slurry leakage amount is reduced; on the other hand, when the precast beams of other models are reformed, only the lower end die needs to be replaced, the lower end die can be compressed through the up-and-down adjustment of the upper end die, and the upper end die is suitable for the precast beams of various models, so that the whole end die does not need to be replaced, and the universality of the die is improved.

Detailed Description

As shown in fig. 1, the present embodiment provides a precast beam forming mold including a pair of side molds 1 arranged opposite to each other, and a pair of upper and

lower end molds

2 and 3 closing end portions of the side molds.

The side die 1 is a channel steel type die, two ends of a web plate of the side die are respectively provided with a pair of long round holes 11 arranged along the height direction of the die, and the pair of long round holes are used as connecting holes so as to be convenient for assembling the upper end die 2.

As shown in fig. 2 and 3, the upper end die 2 is a channel steel type integral piece; the waist plate is provided with a mounting hole 21 for mounting a shear key 4, the waist plate is provided with two sliding grooves 22, the bottom ends of the sliding grooves are provided with a limiting table 23, the sliding grooves are internally provided with sliding blocks 24 capable of sliding up and down along the sliding grooves, each sliding block 24 comprises a T-shaped sliding rod 241 and a plugging plate 242, each plugging plate is an arc plate which is arranged downwards, and the bottom ends of the rod parts of the T-shaped sliding rods extend out of the limiting table and are connected with the plugging plates; a pair of round holes 25 are arranged on the two legs of the utility model and used as positioning holes; the upper end die is locked with the side die 2 through a fastener penetrating through the positioning hole and the connecting hole, and the lower end die 3 is tightly pressed on the die table.
