Description

Technical Field

[0001] The utility model belongs to the technical field of molds, in particular to a box beam chamfering mold which is easy to demould. Background Art

[0002] A box girder is a type of beam used in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, similar to a box, hence the name. In the beam manufacturing process, one of the necessary large-scale construction equipment is the supporting mold that forms the box girder body - the box girder mold.

[0003] It is difficult to demould the box girder mold. The operator needs to enter the inner mold to remove some bolts to shrink the inner mold, and then connect the inner mold to the traction mechanism for demoulding. If the personnel inside and outside the mold do not cooperate properly, casualties will occur.

[0004] Therefore, we proposed a box girder chamfering mold that is easy to demould to solve the above problems. Utility Model Content

[0005] The utility model aims at the problem that the box beam mold is difficult to demould in the prior art, and proposes the following technical solutions:

[0006] A box beam chamfering mold that is easy to demould comprises a bottom plate and a side mold, wherein the bottom plate and two sets of side molds are assembled into a chamfering mold through a splicing mechanism;

[0007] The top ends of the two ends of the sliding panel also are provided with a toothed structure, and the toothed structure is designed so that the sliding panel can be easily connected to the track seat and the track seat, and the two toothed structures are convenient to use and can be easily connected.

[0008] With the use of the splicing mechanism, the bottom plate and the side templates can be easily demoulded and disassembled, the operation is convenient, and no internal and external coordination is required for operation, which improves the safety factor of the device during use.

[0009] As a preferred embodiment of the above technical solution, a side handle is fixedly installed in the middle of the outer side wall of the side panel.

[0010] Under the pulling action of the side handle, the side plate and the limit rod can be conveniently driven to move outward, thereby improving the working efficiency of the device during use.

[0011] As a preferred embodiment of the above technical solution, two groups of fixing protrusions are inserted into the bottom end of the plug-in block, and the bottom ends of the fixing protrusions are fixedly mounted on the bottom end of the inner wall of the first limiting groove.

[0012] The "mushroom" shape of the fixing protrusion allows the plug-in block to be stably plugged into the inner side of the first limiting groove. The arc-shaped material at the top of the fixing protrusion is rubber, so that it can be plugged into the outer wall of the bottom end of the plug-in block through elastic deformation.

[0013] As a preferred embodiment of the above technical solution, a limit block is fixedly installed on the bottom end of the inner wall of the side formwork, and the bottom end of the limit block is plugged into the top end of the base plate.

[0014] Under the plug-in action of the limit block, the plug-in stability between the side formwork and the bottom plate is further improved, ensuring stable efficiency during the splicing process.

[0015] The beneficial effects of the utility model are:

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, in the embodiment of the utility model: it includes a bottom plate 1 and a side template 2, and the bottom plate 1 and two sets of side templates 2 are assembled and assembled into a chamfering mold through a splicing mechanism;

[0024] The splicing mechanism includes a plug-in block 3 fixedly installed in the middle of the bottom end of the side template 2, and the bottom ends of the plug-in blocks 3 are all plugged into the inner side of the first limit groove 5, the first limit groove 5 is arranged on both sides of the top of the bottom plate 1, and the middle of the outer wall of the plug-in block 3 is plugged with a limit plug rod 8, and the outer top end of the limit plug rod 8 passes through the bottom plate 1 and the outer wall of the guide bottom plate 7 and is installed in the middle of the inner wall of the side plate 9, and the middle of the upper and lower ends of the side plate 9 is fixedly installed with a slider 12, and the slider 12 is slidably connected to the outer wall of the slide rod 13, and the two ends of the slide rod 13 are fixedly installed in the middle of the upper and lower ends of the side plate 9. The side top end is fixedly installed in the middle of the inner wall of the third limiting groove 15, and the third limiting groove 15 is symmetrically opened at the upper and lower ends of the inner wall of the second limiting groove 10, and the second limiting groove 10 is symmetrically opened at the bottom end of the outer wall of the guide bottom plate 7. A return spring 14 is welded in the middle of the inner wall of the slider 12, and the inner top end of the return spring 14 is welded in the middle of the inner wall of the third limiting groove 15. The middle part of the return spring 14 surrounds the outer wall of the slide rod 13, and the top of the guide bottom plate 7 is fixedly installed at the bottom end of the outer wall of the side template 2.

[0025] The side plate 9 is pulled outward under the sliding action of the slider 12 and the slide rod 13 in cooperation with the elastic potential energy of the reset spring 14, and the limit plug rod 8 is driven to move outward to the maximum limit value. At this time, the plug-in block 3 is inserted into the inner side of the first limit groove 5 under the guidance of the guide bottom plate 7. After the plug-in work of the bottom plate 1 and the two sets of side templates 2 is completed, the side plate 9 is loosened again, so that the inner side of the limit plug rod 8 is driven to be plugged into the outer wall of the plug-in block 3 under the action of the elastic reaction force of the reset spring 14, completing the locking and splicing work between the bottom plate 1 and the two sets of side templates 2;

[0026] With the use of the splicing mechanism, the bottom plate 1 and the side template 2 can be easily demoulded and disassembled, which is convenient to operate and does not require internal and external coordination for operation, thereby improving the safety factor of the device during use.

[0027] like Figure 2 As shown, a side handle 11 is fixedly installed in the middle of the outer side wall of the side plate 9.

[0028] Under the pulling action of the side pull handle 11, the side plate 9 and the limiting rod 8 can be conveniently driven to move outward, thereby improving the working efficiency of the device during use.

[0029] like Figure 2 As shown, two groups of fixing protrusions 6 are inserted into the bottom end of the plug-in block 3 , and the bottom ends of the fixing protrusions 6 are fixedly mounted on the bottom end of the inner wall of the first limiting groove 5 .

[0030] Due to the "mushroom" shape of the fixing protrusion 6, the plug-in block 3 can be stably plugged into the inner side of the first limiting groove 5. The arc-shaped material at the top of the fixing protrusion 6 is rubber, so that it can be plugged into the outer wall of the bottom end of the plug-in block 3 through elastic deformation.

[0031] like Figure 1 and Figure 2 As shown, a limit block 4 is fixedly installed at the bottom end of the inner wall of the side formwork 2, and the bottom end of the limit block 4 is plugged into the top end of the bottom plate 1.

[0032] Under the plug-in effect of the limit block 4, the plug-in stability between the side template 2 and the bottom plate 1 is further improved, thereby ensuring stable efficiency during the splicing process.

[0033] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
