[0023] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Example:

[0025] See also Figures 1-6 , the utility model provides a technical solution:

[0026] An infrared heating double-station vacuum plastic forming machine includes a frame 1, a forming mold 2 is fixedly installed at the bottom end of the frame 1, an infrared heating plate 3 is fixedly installed on the top of the frame 1, a lifting frame 4 is slidably connected to the inside of the frame 1, a lifting mechanism 5 is fixedly installed on the outside of the lifting frame 4, two groups of processing stations 6 are slidably connected to the inside of the lifting frame 4, and positioning plates 7 are movably installed on the tops of the two groups of processing stations 6. A processing workpiece 8 is embedded between the processing station 6 and the positioning plate 7.

[0027] First, a first positioning ring 201 is fixedly connected to the outside of the forming mold 2, a plurality of suction holes 202 are provided on the top of the forming mold 2, a suction pipe 203 is fixedly connected to the bottom of the forming mold 2, and the plurality of suction holes 202 are all connected to the suction pipe 203. After the workpiece 8 is installed between the processing station 6 and the positioning plate 7, the workpiece 8 is first heated by the infrared heating plate 3, and then the lifting frame 4 is lowered by the lifting mechanism 5 until the workpiece 8 inside the processing station 6 contacts the top of the forming mold 2. The suction pipe 203 is externally connected to a vacuum pump, and under the action of vacuum suction, the heated and softened workpiece 8 is adsorbed on the surface of the forming mold 2 through the vacuum suction of the plurality of suction holes 202, and then solidified and formed on the workpiece 8, and finally cooled to form the desired shape.

[0028] Furthermore, a mounting frame 301 is fixedly installed on the outside of the infrared heating plate 3, and the four corners of the mounting frame 301 are fixedly connected to the frame 1 by screws 302. The infrared heating plate 3 is fixedly installed on the top of the frame 1 through the mounting frame 301, so that after the lifting frame 4 is raised, the workpiece 8 is heated and softened by the infrared heating plate 3.

[0029] Then, the lifting mechanism 5 includes a motor 501 fixedly installed at the bottom left end of the frame 1, a threaded rod 502 fixedly installed on the driving end of the motor 501, and the top of the threaded rod 502 is rotatably connected to the frame 1 through the mounting frame 503, the left end of the lifting frame 4 is threadedly connected to the threaded rod 502 through the connecting frame 504, and two sets of sliding sleeves 505 are fixedly connected to the left and right ends of the lifting frame 4. The sliding sleeves 505 are slidably connected to the frame 1 through the sliding rod 506. When the motor 501 is started, the threaded rod 502 is driven to rotate, and the lifting frame 4 is driven to move up and down under the connection of the connecting frame 504. At the same time, under the sliding connection between the sliding sleeve 505 and the sliding rod 506, the lifting frame 4 is stably driven to move.

[0030] Secondly, the left and right ends of the processing station 6 are fixedly connected with a slide bar 601, and the slide bar 601 is slidably connected to the lifting frame 4 through the slide groove 602. The bottom of the processing station 6 is fixedly connected with a second positioning ring 603. When the workpiece 8 is vacuum-formed, the lifting frame 4 is first lowered to install the workpiece 8 on the inner side of the two groups of processing stations 6, and then the lifting frame 4 is raised to heat and soften the workpiece 8 using the infrared heating plate 3, and then the lifting frame 4 is lowered to make the workpiece 8 contact with the forming mold 2 for vacuum forming. After the workpiece 8 is vacuum-formed, the lifting frame 4 is raised again, and then the slide bar 601 and the slide groove 602 are slid together. Under the dynamic connection, two groups of processing stations 6 are slid simultaneously, and the other group of processing stations 6 is moved to the inner side of the frame 1, and the vacuum-formed workpiece 8 is moved out from the inner side of the frame 1. At this time, the infrared heating plate 3 is used to heat and soften the new workpiece 8, while the vacuum-formed workpiece 8 is cooled on the outside of the frame 1 for easy removal. Finally, the lifting frame 4 is lowered again to vacuum-form the new workpiece 8, and the vacuum-formed workpiece 8 can be taken out at this time, thereby forming a double-station continuous alternation for vacuum forming production, thereby avoiding the waste of heating time and the loss of heat energy, and greatly improving work efficiency.

[0031] Finally, the four corners of the top of the processing station 6 are fixedly connected with positioning columns 701, and the four corners of the positioning plate 7 are slidably connected to the positioning columns 701 through positioning holes 702. The left and right ends of the top of the positioning plate 7 are fixedly connected with operating handles 703. When the workpiece 8 is subjected to vacuum forming, the positioning plate 7 is first opened using the operating handle 703, and then the workpiece 8 is placed into the inner side of the processing station 6, and then the positioning holes 702 are aligned with the positioning columns 701 to cover the positioning plate 7, so that the workpiece 8 is positioned and installed inside the processing station 6. After the processing station 6 is lowered during vacuum forming production, the second positioning ring 603 presses against the first positioning ring 201 to form a sealed space, and then the workpiece 8 is vacuum formed.

[0032] In this embodiment, the implementation scenario is specifically as follows: when the workpiece 8 is being vacuum-formed, the lifting frame 4 is first lowered to install the workpiece 8 on the inner sides of the two groups of processing stations 6, and then the lifting frame 4 is raised to heat and soften the workpiece 8 using the infrared heating plate 3, and then the lifting frame 4 is lowered to make the workpiece 8 contact with the forming mold 2 for vacuum forming. After the workpiece 8 is vacuum-formed, the lifting frame 4 is raised again, and then the two groups of processing stations 6 are slid at the same time under the sliding connection of the slide bar 601 and the slide groove 602, and the other group of processing stations 6 is moved to the inner side of the frame 1, and the vacuum forming processing stations 6 are moved to the inner side of the frame 1. The workpiece 8 is moved out from the inner side of the frame 1. At this time, the infrared heating plate 3 is used to heat and soften the new workpiece 8, while the vacuum-formed workpiece 8 is cooled on the outside of the frame 1 for easy removal. Finally, the lifting frame 4 is lowered again to vacuum-form the new workpiece 8, and the vacuum-formed workpiece 8 can be taken out at this time. The entire operation process is simple and convenient. Compared with the existing vacuum vacuum forming machine, the utility model can form a double-station continuous alternation for vacuum forming production through design, thereby avoiding the waste of heating time and the loss of heat energy, thereby greatly improving work efficiency.
