[0020] Example 1, see Figure 1 and Figure 2 The invention discloses a mold opening device for a T-beam casting mold. The T-beam comprises a middle beam 1 extending along the longitudinal direction of the bridge and a top beam 2 connected to the upper end of the middle beam.

[0021] The utility model includes a track 54, a mold base 55 slidably connected to the track, a T-beam casting mold 56 arranged on the mold base, and a mold opening device 58 arranged beside the track. The T-beam casting mold includes a bottom mold plate 60 connected to the mold base, two side molds 61 and two end molds distributed on the mold base in a transverse manner and capable of opening and closing, and the bottom mold plate, the side molds and the end molds surround a cavity for casting the T-beam. The bottom mold plate includes a bottom mold plate frame 62 and a bottom plate 63 fixed on the bottom mold plate frame. The side mold includes a plate body and a mold frame 64 supporting the plate body. The plate body includes an upper vertical plate 65 aligned with the side of the top beam, an inclined plate 66 supporting the top beam, and a lower vertical plate 67 aligned with the side of the middle beam, which are arranged in sequence from top to bottom. The lower end of the side mold is also provided with a base frame 74 connected to the mold base. The bottom frame is provided with a plurality of inclined support rails 75 distributed along the longitudinal bridge direction. The inclined support rail has one end higher than the other end facing the middle of the cavity. The lower end of the side mold is provided with a slider 90 slidably connected to the inclined support rail. The inclined support rail includes an upper plate 76 and a middle plate 77 connected to the middle of the lower surface of the upper plate. The two ends of the upper plate extend out of the middle plate. Slide grooves are provided at the two ends of the lower surface of the slider. The two end edges of the upper plate are correspondingly penetrated and slidably connected in the slide grooves. A positioning block 78 is provided at the lower end of the inclined support rail to prevent the slider from falling out of the support rail.

[0022] The mold opening device includes two telescopic pullers distributed on both sides of the track for pulling the two side molds one by one. The telescopic puller includes a mold opening part fixing frame 83 and a telescopic pull rod 84 hinged at one end to the mold opening part fixing frame, and the other end of the telescopic pull rod is detachably hinged to the side mold. The telescopic pull rod is connected to the template frame.

[0023] When the mold is opened, the side mold is driven to move downward along the inclined support track by contraction of the pull rod to open.

[0024] Embodiment 2 is different from Embodiment 1 in that:

[0025] See also Figures 3 to 5 The lower vertical plate is provided with a plurality of long holes distributed along the longitudinal bridge direction. The long holes are sealed by a sealing template 85 abutting against the surface of the side of the lower vertical plate facing the template frame. The sealing template is provided with a pit-forming protrusion 86 penetrating in the long hole. The pit-forming protrusion exceeds the surface of the side of the lower vertical plate away from the template frame. The sealing template is connected to the template frame by pressing the cylinder 87. The pit-forming protrusion and the strip-shaped hole are sealed and abutted together. The pit-avoiding protrusion and the sealing template are connected together by a transition arc surface, and the transition arc surface fits and abuts against the lower vertical plate. The bottom frame is placed on the mold base, and the bottom frames of the two side molds are connected to the bottom template through a telescopic rod 88. The telescopic rod is specifically a double-headed screw with a threaded hole. The double-headed screw is rotated to change the depth of the double-headed screw screwed into the threaded hole to achieve telescoping. The bottom template also includes a bottom plate lifting structure 89 that drives the bottom plate to rise and fall.

[0026] When opening the mold, first press the cylinder to pull the sealing template away from the middle beam to the pit to form a convexity sunken into the long hole, and then contract the telescopic pull rod to make the side mold tilt down to open the mold. When the side mold is tilted and pulled down, the bottom plate rises, thereby generating a shearing effect between the side mold and the middle beam, so that the middle beam can be more reliably disconnected when it is bonded to the side mold.
