A formwork component shaping mould

Abstract

The invention relates to a die body component forming die assembly, which comprises a side die face (1) and a lower die face (2), a male die is surrounded by the side die face (1) and the lower die face (2). The invention is characterized in that the side die face (1) and the lower die face (2) of the male die is composed of a die plate (3), and the male die is formed by splitting one lower die face die plate and four side die face die plates, a splitting device (4) is arranged on the splitting die plate (3), at least one of a convex structure (5) or the concave structure (6) is arranged at least one corner part of the die face. The invention is suitable for manufacturing a thin wall pipe or a thin wall box, in particular suitable for manufacturing an opened thin wall pipe and an opened thin wall box.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of February 27, 2004, the application number of 200410005683.6, 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 positive mold, as can be seen from their drawings, it includes a side mold surface and a lower mold surface (or a top mold surface), and the side mold surface and the lower mold surface form a male mold, which is the male mold of the overall template. In the actual use process, it is inconvenient to demould, and the open thin-walled tube or thin-walled box is easily damaged, especially when the wall surface of the formwork member is provided with a convex or concave structure, it is even more inconvenient to demould
