Abstract

The utility model relates to a mould that is used for the roll forming of a gypsum ceiling board, which consists of a bed die and a cover mold, wherein, the four straight-angle embedding rims on the outer frame of the cover mold is connected with the four taperzoid embedding rims on the inner frame of the die bed in an embedding way and completely covers the inner frame of the die bed. A convex hanging strip that is arranged on the outer frame rim of the cover mold is connected with a concave hanging port on the outer frame rim of the die bed in an embedding way. One end of the outer frame of the bed die is provided with a flash groove. The mould can be formed by the mechanical force or the labor force; the produced gypsum ceiling board has beautiful exterior shape, good evenness and stable size.

Description

A kind of mould that is used for the roll forming gypsum plaster ceiling board

Technical field

The utility model relates to architectural decoration material field, belongs to a kind of mould that is used for the roll forming gypsum plaster ceiling board.

Background technology

At present, the mould of gypsum plaster ceiling board is made up of a bed die and a cover mold, and cover mold only covers the partly middle of bed die inside casing, and the edge at inside casing four sides is wrapped up in and exposed outside; Between bed die and the cover mold without any being connected.Use the gypsum plaster ceiling board outward appearance of this Mold Making coarse, poor flatness, size instability.

Summary of the invention

In order to overcome the defective of existing gypsum plaster ceiling board mould, the utility model provides this one by one mould of a kind of Embedded totally-enclosed mould to be made up of a bed die and a cover mold, cover mold can cover whole inside casings of bed die, between bed die and the cover mold mutually embedding connect.

The technical scheme that its technical problem that solves the utility model adopts is: the edge at bed die inside casing four sides is provided with a trapezoidal embedding limit, edge at cover mold housing four sides is provided with a square embedding limit correspondingly, and the outer edge of cover mold embeds the interior edge of bed die and covers whole inside casings of bed die.One side of the outer edge of bed die is provided with a spill mouth hanging, and the outer corresponding side of edge of cover mold is provided with a convex and hangs bar, and the extension bar of cover mold embeds the mouth hanging of bed die and plays control bed die and the mutually clamped effect of putting of cover mold.The outer edge side opposite with mouth hanging of bed die is provided with a u shape flash groove.

The beneficial effects of the utility model are: this mould can be used machinery or manpower roll forming, the gypsum plaster ceiling board good looking appearance of made, and flatness is good, dimensionally stable.

Among the figure: 1, bed die inside casing, 2, the trapezoidal embedding limit of bed die inside casing, 3, the bed die mouth hanging, 4, the bed die flash groove, 5, the square embedding limit of cover mold housing, 6, cover mold hangs bar, 7, gypsum slurry, 8, circular drum.

The specific embodiment

By Fig. 1 to 9 as can be known, the utility model is made up of a bed die and a cover mold, is characterized in: cover mold can all cover the inside casing of bed die, between bed die and the cover mold by the trapezoidal embedding limit at bed die inside casing four sides and cover mold housing square embedding limit on four sides mutually embedding be connected.

The convex extension bar of the outer edge of cover mold described in the utility model and the spill mouth hanging embedding connection mutually of the outer edge of bed die.The opposite direction of described bed die mouth hanging is provided with u type flash groove.

Of the present utility model with reference to technology: gypsum slurry (7) is poured bed die inside casing (1) into, cover mold is hung bar (6) embed bed die mouth hanging (3), use circular drum (8) to push down cover mold then and hang bar one end, along the roll extrusion of arrow direction indication, the square embedding limit (5) that makes the cover mold housing and the trapezoidal embedding limit (2) of bed die inside casing be the embedding type that is formed by connecting mutually.Unnecessary gypsum slurry can flow into flash groove (4).

Claims

1, a kind of mould that is used for the roll forming gypsum plaster ceiling board, this mould is made up of a bed die and a cover mold, it is characterized in that: cover mold can all cover the inside casing of bed die, between bed die and the cover mold by the trapezoidal embedding limit at edge four sides in the bed die and the outer edge of cover mold square embedding limit on four sides mutually embedding be connected.

2, mould according to claim 1 is characterized in that, the convex extension bar of the outer edge of cover mold and the spill mouth hanging embedding connection mutually of the outer edge of bed die.

3, mould according to claim 1 is characterized in that, the direction that the bed die mouth hanging is opposite is provided with u type flash groove.
