Embodiment 1
[0024] Example 1: see Figure 1-6 , The present invention provides a technical solution: a hydraulic internal mold system for a prefabricated box girder, comprising a box girder hydraulic internal mold device, and the box girder hydraulic internal mold device includes a telescopic box girder internal mold, a hydraulic support mechanism, a demoulding mechanism and The booster, the inner mold of the telescopic box girder is a four-section structure and is respectively an upper module 1, a lower module 2, a capsule inflatable column 1 3 and a capsule inflatable column 2 4. The built-in hydraulic support mechanism includes a lateral pusher 5 and a The diverters 6 on both sides, the lateral pusher 5 is built in the interior of the lower module 2 and the upper end is connected with the upper module 1, two groups of diverters 6 are symmetrically installed on both sides of the lower module 2 and cooperate with the capsule inflation column. 3. The capsule inflation column 24 is used. T...
Embodiment 2
[0025] Example 2, as figure 1 and 2 , the technical solution of this embodiment is an upper module 1 installed on the above-mentioned box girder hydraulic inner mould device, the upper module 1 is composed of several groups of capsule-type sub-mold cushions 14, and the inside of the capsule-type sub-mold cushions 14 is provided with movable In the inner cavity 15, a bump 16 is formed in the middle of the movable inner cavity 15 and guide rails 17 are formed on both sides. Two sets of inflatable tubes 18 are symmetrically installed on the bumps 16. The outer end of the inflatable tube 18 is connected with a gas injection tube 19, and the guide rails 17 Several groups of rotors 20 are evenly installed on the top, and such a design facilitates the lateral movement of the capsule-type sub-mold pad 14 along the movable inner cavity 15 .
[0026] Among the adjacent two groups of capsule-type sub-mold mats 14 , one group of capsule-type sub-mold mats 14 is movably inserted into the ...
Embodiment 3
[0029] Example 3, as image 3 and 4 , the technical solution of this embodiment is a lateral pusher 5 installed on the above-mentioned box girder hydraulic inner mold device, and the lateral pusher 5 includes a support plate 23 installed on the end of the lower die set 2 and two plates installed on the support plate 23. A group of electric push rods 24, the power output ends of the two groups of electric push rods 24 are connected with a baffle plate 25, several groups of push rods 26 are evenly installed on the inner side of the baffle plate 25, and a movable block 27 is connected to the ends of the several groups of push rods 26, Three sets of hydraulic cylinders 28 are evenly installed on the movable block 27. The upper ends of the three sets of hydraulic cylinders 28 are connected to the upper module 1, and the baffle plate 25 is pushed to move laterally by the electric push rod 24, thereby driving the movable block 27 to move. The purpose of stretching the inner mold of ...
