Technical Field

[0001] The utility model relates to the technical field of plastic sheet processing, in particular to a plastic sheet hot pressing processing and molding device. Background Art

[0002] Plastic sheet thermoforming is a special plastics processing method for processing thermoplastic plastic sheets into various products. This method involves heating the thermoplastic plastic sheet to its softening temperature. Then, under the action of external forces such as mechanical pressure, vacuum or compressed air, the heated and softened sheet is pressed against the contour of the mold and cooled to form the product.

[0003] The current hot pressing molding process of plastic sheets requires three steps: hot pressing molding, cooling and shaping, and product removal, and all three steps are completed in the same equipment. The time consumed in the cooling and shaping and product removal processes reduces the processing efficiency. Therefore, we propose a plastic sheet hot pressing molding equipment.

It solves the problem that in the current hot pressing forming of plastic sheets, the three steps of hot pressing forming, cooling and shaping, and product removal are required, and the three steps are completed in the same equipment, and the time consumed in the cooling and shaping and product removal processes reduces the processing efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plastic sheet hot pressing processing and molding equipment, comprising a conveyor frame, a conveyor chain plate is arranged inside the conveyor frame, and a plurality of molding molds are fixedly installed at equal intervals on the outer surface of the conveyor chain plate, and a molding cavity is provided on the outer surface of each molding mold away from the conveyor chain plate.

The lower surface of the sliding end of the electric slide is fixedly connected to a cylinder, and the end of the cylinder output shaft is fixedly connected to a vacuum suction cup.

[0009] Preferably, a window is provided on a side of the front surface of the fixing frame close to the vacuum suction cup, and the electric slide passes through the window.

[0010] Preferably, a flow cavity is provided inside the cooling platen, and a cold water pipe and a return pipe are fixedly connected to the upper surface of the cooling platen near the front surface and the rear surface respectively.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

The plastic sheet is placed in the forming cavity inside the forming mold, and the conveying chain plate drives the forming mold to move. When it moves to the bottom of the hot pressing plate, the hydraulic cylinder drives the hot pressing plate to descend, and completes the plastic sheet inside the forming mold.

The conveying motor 3 drives the active roller 14 to rotate, thereby driving the conveying chain plate 4 and the driven roller 17 to rotate. A plurality of forming molds 5 are equidistantly fixedly installed on the outer surface of the conveying chain plate 4, and a forming cavity 6 is provided on the side of the outer surface of each forming mold 5 facing away from the conveying chain plate 4. The plastic sheet is hot-pressed inside the forming cavity 6, and a plurality of supporting rollers 15 are equidistantly rotatably installed inside the conveying frame 1.

A hydraulic cylinder 16 and an electric slide 10 are fixedly installed on both sides of the fixing frame 7. The end of the output shaft of the hydraulic cylinder 16 is fixedly connected to a cross plate 19. A hot press plate 18 and a cooling press plate 21 are fixedly installed on both sides of the lower surface of the cross plate 19. The hot press plate 18 and the cooling press plate 21 have the effect of heating and pressing the plastic sheet inside the molding cavity 6 to soften the plastic sheet and form it inside the molding cavity 6, while the cooling press plate 21 is used for hot pressing. The cooling platen 21 has the function of cooling the finished product. A flow cavity 20 is provided inside the cooling platen 21.
