The connecting rod 7 is made of threaded steel, and the connecting rod 7 is obliquely connected to the bottom support frame 1 to ensure that the handles 8 on both sides can move closer to the middle to overlap or fit during work, which is convenient for grasping; the handle 8 is an inverted triangle structure, and designing the handle 8 as an inverted triangle structure can also facilitate the grasping of construction workers. A ramp plate 9 is also provided on one side of the bottom support frame 1, and the ramp plate 9 is located on the opposite side of the positioning member 3. The ramp plate 9 is convenient for the staff to carry the component to the bottom support frame 1. In actual use, the component can be lifted up together with the mold with the feet, and then the ramp plate 9 is inserted under the component and the mold, and then the component and the mold are pushed onto the bottom support frame 1 with the feet.

[0021] Based on the support 4, the pressing member 6, the connecting rod 7 and the handle 8 are symmetrically arranged in two, and the connecting rod 7 can raise the height of the handle 8 so that the staff can work without bending over.

[0022] The clamping member 6 is made of an "L" shaped angle steel. The clamping member 6 can contact and clamp the mold through the rotation of the pin 5. Figure 1 and Figure 2 ,exist Figure 2In the embodiment, the pressing member 6 is in an open state. In this state, the cast component, i.e., the column cap, can be placed on the bottom support frame 1 together with the casting mold. Since the component is adhered to the mold at this time, the mold can be placed in the positioning member 3. The positioning member 3 described here functions like a card slot. The mold and the component slide into the groove of the positioning member 3 together. The positioning member 3 positions the mold in the up and down directions. Not only that, when the mold cannot be pushed in further, it means that the mold has been pushed into place.

[0023] The positioning member 3 is composed of an "L"-shaped column and an "L"-shaped shield, wherein the "L"-shaped shield is arranged on the surface of the "L"-shaped column and extends toward the center of the opening 2 to form a pressing plate, which can press the edge of the mold;

The number of the centering correction plates 10 is at least two, wherein the curved plate 1002 is an elastic structure, and the curved plate 1002 is suspended between the ramp plate 9 to ensure that the curved plate 1002 can more freely adjust a certain degree of curvature.

[0025] Subsequent reference Figure 1 , move the handles 8 on both sides closer to the middle, and then Figure 2 The status changes to Figure 1 Status in.

[0026] Working process:

[0027] In order to facilitate the demoulding of the component, i.e., the bridge railing column cap, the handles 8 on both sides are first separated, and the state of the device is as follows Figure 2 As shown, the component and the mold are then pushed into the positioning member 3 through the ramp plate 9; during the pushing process, the centering correction plate 10 adjusts the position of the mold and the component to ensure that they are pushed into the positioning member 3 accurately and quickly. It is worth noting that the purpose of the positioning member 3 here is mainly to facilitate the positioning of the mold to prevent the frame of the bottom support frame 1 from blocking the component during the demoulding process due to the position deviation of the mold. After the positioning member 3 is set, the operator can quickly and accurately put the mold in;

[0028] Then you can put the handles 8 on both sides together, and the state is like Figure 3As shown, the pressing members 6 on both sides press the top of the mold, and the bottom support frame 1 supports the bottom of the mold. In this state, the device and the mold form a whole. Then the staff grabs the handle 8 and vibrates up and down, and the component falls off from the opening 2 in the center of the bottom support frame 1 under vibration;

[0029] When the component falls off from the opening 2, separate the handles 8 on both sides, and hold one handle 8 with both hands. When the handles 8 on both sides are separated, the clamping member 6 will not have a clamping effect on the mold. At this time, turn the ramp plate 9 toward the ground and vibrate it slightly downward to throw the mold off the device.
