Technical Field

[0001] The utility model relates to the field of tunnel invert block moulds, in particular to a drainage hole split type mould core demoulding structure. Background Art

[0002] The tunnel boring machine (TBM) is a systematic, intelligent, and factory-based high-efficiency tunnel excavation construction machinery that can excavate a tunnel in one go and simultaneously complete the entire process of tunnel construction, including excavation and advancement, slag transportation, ventilation and dust removal, guidance control, support lining and advance treatment, wind, water, electricity and material supply, and realizes automated monitoring, making it suitable for tunnel construction in ultra-long underground caverns.

The reinforced concrete arch blocks are prefabricated by mold casting. The prior art 202120162208.9 discloses an integral tunnel arch block mold. Although it can be cast in one time, the concrete will fit firmly to the mold surface after solidification, which makes demoulding more troublesome. Utility Model Content

[0006] Preferably, the two cores of the core assembly are divided into an upper template and a lower template; the upper template and the lower template are hinged to each other at the joint, and the hinge position is located at the inner wall of the upper template and the lower template.

[0007] Preferably, the upper template and the lower template are attached to the upper template and the lower template on the other side to form a uniformly inclined surface.

[0008] Preferably, multiple groups of the flip support assemblies each include an upper pipe sleeve with one end hinged to one end of the top of the upper template and with internal threads, a lower pipe sleeve with one end hinged to the lower template and with internal threads, and a threaded support rod with both ends respectively threadedly connected to the upper pipe sleeve and the lower pipe sleeve and with opposite threads at both ends.

[0010] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0011] The utility model drives the top and bottom of the two mold cores of the mold core assembly to flip inward by the flipping support assembly, which can effectively separate the two mold cores from the prefabricated part, thereby realizing demoulding, and the flipping support assembly can also support the two mold cores to avoid deformation during pouring.

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Attached Figure 1-3 The utility model is a split-type core demoulding structure for drain holes, comprising a core 11 component, and multiple groups of flip support components 2 respectively arranged at both ends of the inner cavity of the core 11 component; the core component 1 comprises two cores 11 that can be flipped inwards; the top and bottom ends of the two cores 11 are attached to each other; the multiple groups of flip support components 2 are respectively used to support the two cores 11 and drive the top and bottom of the two cores 11 to flip inwards; the two cores 11 of the core component 1 are divided into upper molds Plate 111 and lower template 112; the upper template 111 and lower template 112 are hinged to each other at the fitting part, and the hinge position is located at the inner wall of the upper template 111 and the lower template 112; multiple groups of flip support components 2 all include an upper pipe sleeve 21 with one end hinged on one end of the top of the upper template and with internal threads, a lower pipe sleeve 22 with one end hinged on the lower template 112 and with internal threads, and a threaded support rod 23 with both ends respectively threadedly connected to the upper pipe sleeve 21 and the lower pipe sleeve 22 and with opposite threads at both ends.

[0019] Furthermore, the upper template 111 and the lower template 112 are attached to each other with an evenly spaced inclined surface with the upper template 111 and the lower template 112 on the other side, so as to support each other.

[0020] Furthermore, a connection block 3 is provided in the middle of each of the plurality of threaded support rods 23; a hole 4 is provided in the middle of the connection block 3, so as to facilitate the insertion of a driving rod for rotation and save manpower.

[0021] When in use: first, insert the two ends of the upper template 111 and the lower template 112 hinged together into one side of the through holes corresponding to the two side templates, and then insert the two ends of the upper template 111 and the lower template 112 hinged together into the other side of the through holes corresponding to the two side templates, and then rotate the threaded support rods 23 at both ends of the upper template 111 and the lower template 112 on one side at the same time. Since the threads at both ends of the threaded support rods 23 are opposite, the upper sleeve 2171 and the lower sleeve 22 will open the upper template 111 and the lower template 112. When they are opened to a fixed size, rotate the threaded support rods 23 at both ends of the upper template 111 and the lower template 112 on the other side to open the upper template 111 and the lower template 112 to a fixed size. Then the upper templates 111 and the lower templates 1 The inclined surfaces at one end of 12 fit each other, and finally the mud is introduced. During the process of introducing the mud, the threaded support rod 23 can also support the upper template 111 and the lower template 112 to avoid deformation. When the mud solidifies, the threaded support rod 23 is rotated in the opposite direction, and then the threaded support rod 23 drives the upper pipe sleeve 21 and the lower pipe sleeve 22 to approach each other, and the upper pipe sleeve 21 and the lower pipe sleeve 22 drive the upper template 111 and the lower template 112 to approach each other. Since the upper template 111 and the lower template 112 are hinged to each other, one end of the upper template 111 and the lower template 112 is flipped inward, so that the upper template 111 and the lower template 112 are separated from the prefabricated part to achieve demolding, and then the upper template 111 and the lower template 112 are taken out. After all the upper templates 111 and the lower templates 112 are taken out in this step, the side mold and the end mold are opened to take out the prefabricated part.

[0022] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
