Shuttering component forming die

Abstract

The invention provides a die shell component forming die, comprising a side die surface (1) and a bottom die surface (2); the side die surface (1) and the bottom die surface (2) enclose a female die; the die shell component forming die is characterized in that the side die surface (1) and the bottom die surface (2) of the female die consist of formworks (3); the female die is formed by the assembly of at least two formworks (3); the assembled formwork (3) is provided with an assembly device (4); at least one corner position of the die surface is provided with at least one structure of a convex structure (5) or a concave structure (6); the convex structure (5) or the concave structure (6) is a section-by-section type or continuous; the convex structure (5) or the concave structure (6) is arranged at two formworks (3) of the corners or two formworks (3) where the corners are assembled at the same time; the die shell component forming die is applicable to manufacturing thin-wall pipes or thin-wall boxes, more particularly to the thin-wall pipes with openings or thin-wall boxes with openings.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of January 20, 2004, the application number of 200410002648.9, and the title of "a mold for molding shell components". (1) Technical field [0002] The invention relates to a mold for molding shell components. (2) Background technology [0003] 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 fi...

Problems solved by technology

Such as the female mold, as can be seen from their drawings, it includes a side mold surface and a bottom mold surface, and the side mold surface and the bottom mold surface form a female mold. This kind of female mold is the female mold of the overall template. Among them, demoulding is inconvenient, and the open thin-walled tube or thin-walled box is easily damaged. Therefore, it is urgently needed to develop a new type of mold for forming shell components.
