Formwork element molding mould

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 is characterized in that the side die surface (1) and the bottom die surface (2) of the female die are composed of die plates (3); the female die is formed by the assembling of at least two die plates (3); the assembly position of the die plates (3) is provided with an assembly device (4); at least one die plate (3) is used as a disposable die plate of the die shell component part; the rotation angle position of the die surface is provided with a convex structure (5) or a concave structure (6); the convex structure (5) is a convex bar or a convex block or a convex rod; and or, the concave structure (6) is at least one structure out of a concave trough, a concave hole, a concave cavity, a seam or a hole. The die is applicable for preparing thin-walled pipes or thin-walled boxes and is especially applicable for preparing thin-walled pipes with openings or thin-walled 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 200410002645.5, and the title of "a mold for molding shell components". (1) Technical field [0002] The invention relates to a mold for forming a mold shell component. (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 ...

AI Technical Summary

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.
