Die-shell component forming die

Abstract

The invention provides a mould for molding shuttering components which comprises a side die face (1) and a bottom die face (2). A female die is formed by surrounding the side die face (1) and the bottom die face (2). The invention is characterized in that: the side die face (1) and the bottom die face (2) of the female die are formed by moulding boards (3), the female die is formed by splitting at least two moulding boards (3), the split moulding boards (3) are provided with a split device (4) which merges the moulding boards (3) into one body, at least one moulding board (3) is a part (5) for forming a permanent shuttering component, the split device (4) is arranged on the moulding board (3) of the side die face (1), the split device (4) is arranged at the split position of the moulding boards (3); or the split position of the moulding boards (3) is at the corner position of the die face; or the split device (4) is arranged at the corner position of the die faces between the moulding board (3) of the side die face (1) and the moulding board (3) of the bottom die face (2) or the corner position of the die faces between the moulding boards (3) of the side die face (1). The mould is applicable to making thin wall tubes or thin wall boxes, especially to making thin wall tubes with openings or thin wall boxes with openings.

Description

[0001] This application is a divisional application of an invention patent application with the filing date of January 20, 2004, the application number of 200410002657.8, 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 f...

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.
