Such as the positive mold, as can be seen from their drawings, it includes a side mold surface and a lower mold surface (or a top mold surface), and the side mold surface and the lower mold surface form a male mold, which is the male mold of the overall template. In the actual use process, it is inconvenient to demould, and the open thin-walled tube or thin-walled box is easy to be damaged, and it is difficult to produce thin-walled boxes with perforated tubes with this mold. Therefore, a new type of mold shell component molding is developed. The mold is urgently needed

Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0040] As shown in the accompanying drawings, the present invention includes a side wall mold 1, a bottom mold 2, and a cover mold 3. When forming, the cover mold 3 is covered on the side wall mold 1, and the middle part of the bottom mold 2 is provided with a resistance rod 5 connected to a power supply. , the resistance rod 5 is covered with a rod mold 4, which is characterized in that the material of the rod mold 4 is a water-swellable material. figure 1 It is a structural schematic diagram of an embodiment of the present invention. In each accompanying drawing, 1 is a side wall mold, 2 is a bottom mold, 3 is a cover mold, 4 is a bar mold, and 5 is a resistance rod. In each of the following accompanying drawings, those with the same numbering have the same description. like figure 1 As shown, the cover mold 3 is covered on the side wall mold 1 duri...

A hollow box forming die comprises side wall dies (1), a bottom die (2), and a cover plate die (3). When the hollow box is formed, the cover plate die (3) is covered on the side wall dies (1), an electric resistance rod (5) which is connected with a power supply is arranged in the middle of the bottom die (2), and a rod die (4) is sleeved on the electric resistance rod (5). The hollow box forming die is characterized in that the rod die (4) is made of water-absorbing expansion materials. Therefore, when the hollow box is formed, the rod die made of the water-absorbing expansion materials absorbs water to be saturated, slurries are laid or daubed or sprayed on the rod die which is saturated after water absorption, the side wall dies, the bottom die, and the cover plate die at the same time, or strengthening materials are added to the slurries. When a blank is made, the side wall dies are placed on the bottom die, the cover plate die is covered on the side wall dies, so that the side wall die can be closely connected with the bottom plate die and the blank on the cover plate die, and a product is produced after maintenance and mold release.
Description
(1) Technical field [0001] The invention relates to a hollow box molding die. (2) Background technology [0002] At present, cast-in-place reinforced concrete hollow slabs, especially the non-core-pulling hole-forming process of cast-in-situ reinforced concrete hollow slabs, are generally filled with thin-walled tubes or thin-walled boxes, which can meet the needs of various hollow slabs for evacuating concrete. The applicant applied for an invention patent with the application number 99115665.X and the title "fiber-reinforced thin-walled pipe (box) for reinforced concrete filling and its manufacturing method" on November 29, 1999, and the application number 99115666.8 , the invention patent titled "fiber-reinforced thin-walled box for filling cast-in-place reinforced concrete and its manufacturing method", the thin-walled tube or thin-walled box can be open, and if it has a seal, it can be closed A thin-walled tube or a closed thin-walled box; the mold used in its manufact...
