Forming mold for hollow box

Abstract

The invention relates to a forming mold for a hollow box, which comprises a basin mold (1), a cover plate mold (2) and a rod mold (3), wherein during the forming, the cover plate mold (2) is covered on a basin opening (7) of the basin mold (1) or in the basin opening (7), the rod mold (3) is a movable rod mold. The forming mold is characterized in that a positioning device (31) of the movable rod mold (3) is arranged in the middle of the basin bottom of the basin mold (1). Therefore, during the forming, slurry is firstly and simultaneously paved or applied or sprayed onto the rod mold, the basin mold and the cover plate, or reinforcing materials are simultaneously added in the slurry, after blanks are made, the rod mold applied with the slurry is firstly placed in the middle position at the basin bottom of the basin mold, the positioning device is used for positioning, then, the cover plate mold is covered in the basin opening or on the basin opening so that the basin mold and the blanks on the cover plate mold are tightly connected, and products are obtained through maintenance and demolding. The forming tool has the characteristics that the structure is simple, the manufacture is easy, the cost is low, and the like. In addition, the integral performance of a produced component is very good, so the goal of the forming mold is reached.

Description

(1) Technical field [0001] The invention relates to a molding die for a hollow box. (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 ma...

Problems solved by technology

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
