Technical Field

[0001] The utility model specifically relates to the technical field of double-sheet vacuum forming, in particular to a double-sheet vacuum machine for automobile plastic production. Background Art

[0002] The plastics used in automobiles are formed by hot pressing extraction, but the traditional hot pressing molding machines can only realize the molding of one piece of plastic parts during processing and production, which greatly reduces the production efficiency of the equipment during production.

[0003] After searching, Chinese patent application number CN201020557283.7 discloses a vacuum rubber pad forming device for automobiles; it includes a clamping mechanism, a heating furnace, a vacuum mechanism and a cooling mechanism, a heating furnace and a mold are respectively provided on both sides of the sheet and the plastic sheet is placed on the surface of the blister mold; the outside of the mold is connected to a vacuum mechanism and the heated and softened plastic is pulled down and covered on the mold by vacuuming the mold;

[0004] The structure in the above patent, when vacuum forming, moves the mold upward to make the plastic sheet contact with the sheet upward, and then heats the plastic sheet through the heating furnace to make the plastic sheet vacuum formed. In this way, only one piece of plastic sheet can be effectively processed during the processing. When the car uses double-sided plastic, the structure in the above patent cannot be effectively processed and produced, so it cannot effectively meet the needs.

[0005] In view of the above situation, we provide a double-sheet vacuum machine for automobile plastic production. In this device, a vacuum plate groove is arranged inside the frame. During processing and production, the vacuum plate groove is used to effectively extract negative pressure from the plastic sheet to achieve the fitting of the plastic sheet with the inside of the groove. A top pressure heating plate is also arranged below the vacuum plate groove. During processing and production, the two plastic sheets are pushed upward by the top pressure heating plate to enable the upper plastic sheet to enter the vacuum groove, thereby achieving effective vacuum extraction and compression molding of one plastic sheet. During processing, the two plastic sheets are effectively heated by the top pressure heating plate to achieve integrated molding of the two plastic sheets, thereby greatly improving the production efficiency and quality of the vacuum machine.

[0028] By adopting the above technical solution, when in use, the two plastic sheets are transported separately. When they are transported to the middle of the top pressure heating plate 20 and the vacuum plate groove 31, they stop moving, the top pressure heating plate 20 is pushed up by the push rod 21, and the vacuum plate groove 31 moves downward under the drive of the oil cylinder 30, and contacts with the two plastic sheets respectively. When the vacuum plate groove 31 contacts the plastic sheet, negative pressure is pumped through the second negative pressure pipe 33 to realize vacuum forming of the upper plastic sheet;
