Formwork component forming mold

Abstract

The present invention relates to a shuttering component forming die which comprises lateral templates (1) and is characterized by also comprising a bottom border (2); the bottom border (2) is quadrilateral; the lateral templates (1) are respectively jointed with four edges of the bottom border (2) to form a shuttering component molded annular die; joint devices (3) are arranged at the joint parts of the lateral templates (1) and the bottom border (2); the lateral templates (1) are four pieces and are provided with the joint device (3) between each other; the joint device (3) is at least one of a connecting device (4) or a closing device (5) or a positioning device (6) Thus after the joint device is unscrewed, the shuttering component forming die is very convenient for demoulding; at the same time, the die also has the characteristics of simple structure, easy manufacture, high strength, low cost, and the like, and is fit for manufacturing thin wall pipes or thin wall boxes and particularly fit for manufacturing open thin wall boxes.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of May 25, 2004, the application number of 200410037069.8, 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 for ...

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.
