Technical Field

[0001] The invention belongs to the field of mold production, and in particular relates to a structural improvement of an arc-shaped composite plate mold. Background Art

[0002] like Figure 1 As shown, the existing production process for making curved composite panels requires a set of customized wooden molds. When using the existing wooden molds to make curved composite panels, each radius requires a set of curved wooden molds 1, that is, curved composite panels of different radii require a set of customized molds to composite the composite panels, which is time-consuming and labor-intensive.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] An adjustable arc-shaped composite plate mold includes a base frame, a screw lifting mechanism, a base plate and a cover plate; the base frame is equipped with a screw lifting mechanism; the screw lifting mechanism includes a plurality of screw lifting devices fixed in parallel on the base frame; the screw lifting device includes front and rear screw lifting units, and a roller; the front and rear screw lifting units include front and rear screw lifting machines fixed on the base frame, and a connecting shaft; wherein,

[0006] The front and rear lifts are respectively equipped with front and rear hand cranks, front and rear couplings, and front and rear lifting screws;

[0007] The connecting shaft connects the front and rear hand-crank plates through the front and rear couplings, and the connecting shaft synchronously drives the front and rear lifting screws to perform lifting actions;

[0008] Rollers are mounted between the front and rear lifting screws, and the rollers on the multiple sets of screw lifting devices are arranged in parallel;

[0009] The bottom plate is an aluminum bottom plate, which is laid on multiple rollers arranged in parallel;

[0010] The cover plate is a rubber skin, which covers the composite plate to be processed, and the rubber skin is fixed on the aluminum bottom plate through a pressing strip.

[0011] In the above-mentioned adjustable arc-shaped composite plate mold, the base frame is a steel base frame, and rollers are installed on the steel base frame.

[0012] In the above-mentioned adjustable arc-shaped composite plate mold, a material blocking strip is provided on the aluminum bottom plate, and the material blocking strip and the material pressing strip are placed at the same end of the aluminum bottom plate.

[0026] See also Figures 2 to 8 The invention discloses an adjustable arc-shaped composite plate mold, which comprises a base frame, a screw lifting mechanism, a base plate and a cover plate.

[0027] The base frame of the present invention is a steel base frame 100 , on which rollers 110 are installed; a screw lifting mechanism is also installed on the steel base frame 100 .

[0028] The screw lifting mechanism of the present invention comprises a plurality of screw lifting devices 200 fixed in parallel on the steel base frame 100 .

[0029] The screw lifting device 200 includes front and rear screw lifting units 210 and 220 , and a roller 230 mounted between the front and rear screw lifting units 210 and 220 .

[0030] The front and rear screw lifting units 210, 220 include front and rear screw lifting machines 212, 222 fixed on the steel base frame 100, and a connecting shaft 240 connected between the front and rear screw lifting machines 212, 222, and the connecting shaft 240 connects the front and rear screw lifting machines 212, 222 together.

[0031] The front and rear screw lifting units 210 and 220 also include front and rear lifting bases 211 and 221, which are respectively fixed on both sides of the steel base frame 100, and the front and rear screw lifts 212 and 222 are correspondingly fixed on the front and rear lifting bases 211 and 221.

[0032] The front and rear lifts 212 and 222 are correspondingly provided with front and rear hand cranks 213 and 223 , front and rear couplings 214 and 224 , and front and rear lift screws 215 and 225 .

[0033] The front and rear lifting screws 215 and 225 are provided with front and rear limit grooves 216 and 226 at the top, and the front and rear ends of the roller 230 are respectively placed in the front and rear limit grooves 216 and 226, so that the roller 230 is mounted between the front and rear lifting screws 215 and 225, and the rollers 230 on the multiple groups of screw lifting devices 200 are arranged in parallel.

[0034] The connecting shaft 240 is connected to the front and rear hand crank plates 213 and 223 through the front and rear couplings 214 and 224. When the front and rear hand crank plates 213 and 223 are shaken, the connecting shaft 240 synchronously drives the front and rear lifting screws 215 and 225 to perform lifting actions, so as to adjust the required height of the rollers 230 of each group of screw lifting devices 200 in turn, so that the curvature of the aluminum bottom plate 300 placed on the rollers 230 is consistent with the curvature required by the composite board 500 to be processed, thereby realizing the adjustable curved composite board mold to produce composite boards with different radii and curvatures.

[0035] The bottom plate of the present invention is an aluminum bottom plate 300, which is laid on a plurality of rollers 230 arranged in parallel. When the aluminum bottom plate 300 is laid on the rollers 230, the rollers 230 adaptively roll in the front and rear limiting grooves 216 and 226 to form the required arc shape of the aluminum bottom plate 300. The present invention provides a material stopper strip 310 on the aluminum bottom plate 300 to limit the position of the composite plate 500 to be processed placed on the aluminum bottom plate 300.

[0036] The cover plate of the present invention is a rubber skin 400, which covers the composite board 500 to be processed, and the rubber skin 400 is fixed to the aluminum bottom plate 300 through a press strip 600, so that the composite board 500 to be processed is stably sandwiched between the rubber skin 400 and the aluminum bottom plate 300 for shaping. The stop strip 310 and the press strip 600 are placed at the same end of the aluminum bottom plate 300.

[0037] The steps of using the adjustable arc-shaped composite plate mold of the present invention are as follows:

[0038] Step 1: first, according to the size requirements of the composite board 500 to be processed, adjust the arc size of the aluminum bottom plate 300 to be consistent with the arc size required by the composite board 500 to be processed. The adjustment method is to manually crank the front hand-cranked plate 213 or the rear hand-cranked plate 223 to make the front and rear lifting screws 215 and 225 of the screw lifting device 200 drive the rollers 230 to rise or fall, and adjust the heights of the rollers 230 to be adjusted in turn, so that the arc of the aluminum bottom plate 300 laid on the multiple rollers 230 is consistent with the arc required for processing the composite board 500;

[0039] Step 2: Push one end of the composite board 500 to be processed against the blocking bar 310 and place it along the aluminum bottom plate 300 with the curvature adjusted;

[0040] Step 3, cover the rubber skin 400 and tighten the pressing strip 600 placed on the rubber skin 400 with screws;

[0041] Step 4: add a heavy object, such as a sandbag, to the rubber skin 400, and then use a negative pressure device to extract the air in the rubber skin 400 and the aluminum base plate 300 until the composite board 500 to be processed is shaped.
