Formwork member molding die

Abstract

The invention relates to a shuttering-structure mold which comprises a side mold surface (1) and a base mold surface (2). The side mold surface (1) and the base mold surface (2) enclose into a female mold. The shuttering-structure mold is characterized in that the side mold surface (1) and the base mold surface (2) of the female mold consists of moulding plates (3); the female mold is made by splicing at least two pieces of moulding plates (3); a splicing device (4) is arranged on the spliced moulding plate (3); and a shuttering thickness limit device (5) is arranged on the moulding plate (3). The side mold surface (1) consists of four pieces of moulding plates (3), on which at least one nick (15) is arranged; at least one moulding plate (3) of the female mold is a floor mold, or a platform mold or a split mold. Therefore, the shuttering-structure mold greatly simplifies the structure of molds and reduces the material cost; meanwhile, mold installing and dismounting process are also simplified, so that the shuttering-structure mold become more easier to be used and manufactured. Besides, the shuttering-structure mold also has the advantages of simple structure, easy manufacturing process, high stiffness and low cost, and is applicable to manufacturing thin-walled tubes and thin-walled boxes, especially applicable to manufacturing thin-walled tubes with openings and thin-walledboxes 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 200410002653.X, 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.
