Forming die of thin-wall hollow member

Abstract

The invention relates to a forming die of a thin-wall hollow member, comprising a basin-shaped female die (1). The basin-shaped female die (1) comprises surrounding basin side films (2) and a bottom film (3) and is characterized in that a slurry-covering template (6) is matched with a basin opening of the basin-shaped female die (1), a film surface at one side of the slurry-covering template (6) inwards plugs a hollow member (4) with an opening at one side or a hollow blank (5) with an opening at one side in the basin-shaped female die (1) from the basin opening, a male die is formed by splicing at least two templates, and a splicing device is arranged on the spliced templates so that the templates are extremely convenient to remove after loosening the splicing device. Meanwhile, at least one structure or device for drawing out and demolding the templates is arranged on the spliced templates so that the demolding of the die is more convenient. In addition, the die also has the advantages of simple structure, easy manufacture, high strength, low cost, and the like, is suitable for manufacturing thin-wall tubes or thin-wall boxes, and is particularly suitable for manufacturing thin-wall tubes with openings or thin-wall boxes with openings.

Description

(1) Technical field [0001] The invention relates to a molding die for a thin-walled hollow member. (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...

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 easily damaged. Therefore, it is urgent to develop a new type of thin-walled hollow member forming die.
