Detailed Description
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.
As shown in fig. 1-9, the continuous wallboard production mold comprises an upper circulation mold 1, a lower circulation mold 2 and two side circulation molds 3, which enclose a wallboard forming cavity 4. The upper circulation mould 1 and the lower circulation mould 2 comprise a power system 5 and mould parts, and the two side circulation moulds 3 comprise mould parts and can also comprise power parts, namely driving motors 3-3. The mould part comprises two rotating shafts and an annular mould capable of rotating around the rotating shafts, the annular mould is tightly supported by the two rotating shafts, one side, close to the wallboard forming cavity 4, of the mould part is an inner mould section 3-1-2, and the other side is an outer mould section 3-1-3. The upper circulation die 1, the lower circulation die 2 and the two side circulation dies 3 run synchronously to drive the wallboard in the wallboard forming cavity 4 to move to one side, so that continuous production is realized.
In this embodiment, the mold parts of the upper and lower circulation molds 1 and 2 include upper and lower link plates 1-1 and 1-3, respectively, to which upper and lower base bands 1-2 and 1-4 are attached, respectively, and the upper and lower link plates 1-1 and 1-3 are driven by sprocket wheels 1-5 at both ends, respectively. The sprocket wheel 1-5 is connected to the power system 5 by a chain 1-6.
The side circulation moulds 3 on two sides are annular belts 3-1, the annular belts 3-1 are wound on rotating wheels 3-2 on two sides, the inner side part (the part close to the wallboard forming cavity 4) of the annular belts 3-1 is an inner side mould section 3-1-2, and the outer side part is an outer side mould section 3-1-3. For the rotation of the side circulation mould 3 around the runner 3-2, the side circulation mould 3, for example an endless belt 3-1, must have a certain flexibility in order to prevent bending deformation at the wall plate forming cavity 4, and the inner mould section 3-1-2 of the side circulation mould 3 is connected with at least one support guide 7-1, which support guide 7-1 is supported inside the inner mould section 3-1-2, i.e. on the side of the inner mould section 3-1-2 remote from the wall plate forming cavity 4. The support guides 7-1 provide support to the side circulation mould 3 to keep the inner mould sections 3-1-2 in a straight state so that the side edges of the cast wall panel are straight.
Advantageously, the inner side mold section 3-1-2 of the side circulation mold 3 is pressed by the edges of the upper baseband 1-2 and the lower baseband 1-4, when the upper baseband 1-2 and the lower baseband 1-4 move synchronously, the side circulation mold 3 is driven to move synchronously under the action of the pressing force, and the upper edges and the lower edges of the side circulation molds 3 on two sides are pressed by the upper baseband 1-2 and the lower baseband 1-4, so that the wallboard forming cavity is ensured to be in a closed state, slurry leakage is prevented, and synchronous movement of the upper baseband 1-2, the lower baseband 1-4 and the two side circulation molds 3 is ensured; the side circulation die 3 reversely supports the upper base band 1-2 at the same time, so that sagging of the upper base band 1-2 can be effectively avoided. Wherein, the upper base band 1-2, the lower base band 1-4 and the side circulation moulds 3 on both sides are jointly enclosed into a wallboard forming cavity 4. Advantageously, at least one wheel 3-2 of the side circulation mould 3 is connected with a drive motor 3-3, the drive motor 3-3 being able to act as an auxiliary drive for the movement of the side circulation mould 3.
The outer surface of the side circulation mould 3 is a plane belt, a concave belt or a convex belt for matching the side shape of the wallboard. The side circulation die 3 has an inner surface provided with a guide groove 3-1-1, and the support guide 7-1 extends into the guide groove 3-1-1. The support guides 7-1 may be rollers or slides.
To further prevent bending deformation of the side circulation mold 3, a dam bar 1-7 is provided at the edge of the upper base tape 1-2 and/or the lower base tape 1-4, the upper and lower ends of the inner side mold section 3-1-2 of the side circulation mold 3 are extended to contact with the upper base tape 1-2 and the lower base tape 1-4, and the dam bar 1-7 is contacted with the inner side of the inner side mold section 3-1-2 (i.e., the side away from the wallboard forming cavity 4). So that the upper and lower ends of the inner mold section 3-1-2 are not outwards turned and deformed under the action of the barrier strips 1-7.
In addition, the upper link plate 1-1 and the lower link plate 1-3 each include a chain 1-6 and a pallet, and a horizontal guide rail 7-2 is provided below the chain 1-6 in order to prevent deformation of the lower link plate 1-3 and the lower link plate 1-3, thereby ensuring that the chain 1-6 runs in a horizontal position. Advantageously, in order to prevent upward bending deformation of the upper link plate 1-1, a horizontal press rail 1-12 is provided above the chain 1-6 of the upper link plate 1-1. Further, in order to prevent the deformation of the pallet, a plurality of pallet guides 1-8 are arranged on the back surface of the pallet, and pallet guide rails 7-3 matched with the pallet guides 1-8 are arranged below the pallet guides. The pallet guide 1-8 may be a supporting guide wheel, the pallet guide 7-3 below may be disposed on the frame 6, and the pallet guide 7-3 above is disposed on the main beam 1-11 of the upper circulation mold 1.
In order to prevent the outer mold section 3-1-3 of the side circulation mold 3 from sagging and smoothly running, a plurality of pairs of positioning guide rollers 7-4 are arranged on two sides of the outer mold section 3-1-3, and each pair of positioning guide rollers 7-4 is respectively positioned on two sides of the outer mold section 3-1-3.
The main body supporting portion of the production die of the present example includes a bracket 7 and a frame 6. Wherein the lower circulation mould 2 and the side circulation mould 3 are fixed on a bracket 7, and the upper circulation mould 1 is fixed on a frame 6. Each unit of the frame 6 is shaped like a door, and comprises upright posts 6-1 positioned on two sides of the upper circulation die 1 and a cross beam 6-2 connected with the upper ends of the upright posts 6-1, wherein the horizontal pressing rail 1-12 is arranged on the cross beam 6-2 and corresponds to the chain 1-6. A plurality of door-shaped units are connected together to form a frame 6 integrally. The two sides of the bracket 7 are provided with belt guide frames, and the belt guide frames are provided with the supporting guide pieces 7-1. The bracket 7 is provided with the horizontal guide rail 7-2 (the guide rail of the chain 1-6), the positioning guide roller 7-4 and the supporting plate guide rail 7-3.
