Description

Technical Field

[0001] The utility model relates to the technical field of vacuum thermoplastic thermoforming, in particular to an integrated device for full-automatic vacuum thermoplastic thermoforming. Background Technique

[0002] Vacuum forming is to fix a thermoplastic plastic sheet or sheet on a mold, heat it with a radiation heater to reach the softening temperature, then use a vacuum pump to evacuate the air between the mold and the sheet (blank), so that the sheet (blank) preform is formed according to the mold contour. As the vacuum degree increases, the forming pressure below the preform is only 0.06 - 0.085 MPa, while the air pressure above the preform remains at about 0.1 MPa. After cooling and shaping, compressed air is used to blow the product out of the mold for demolding.

[0025] Furthermore, a heating chamber 8 is opened inside the fixed shell 4, a cooling chamber 9 is opened outside the heating chamber 8 and inside the fixed shell 4. Two ends of the fixed shell 4 are respectively provided with a delivery pipe 10 and a return pipe 11. The delivery pipe 10 and the return pipe 11 are respectively connected to the heating chamber 8 and the cooling chamber 9 through two sets of through slots 12. Inside the two sets of through slots 12 and inside the fixed shell 4, there is a moving block 13 slidably connected. A delivery groove 14 is opened inside the moving block 13. By connecting the delivery pipe 10 and the return pipe 11 to the through slots 12 respectively, the delivery pipe 10 and the return pipe 11 can be respectively connected to the heating chamber 8 and the cooling chamber 9.

[0026] Secondly, a compression spring 15 is provided inside the fixed shell 4 and outside the moving block 13. Inside the fixed shell 4 and outside the two moving blocks 13, there is a moving rod 16. A driving block 17 is provided outside the moving rod 16. By connecting the compression spring 15 to the moving block 13, when the moving block 13 does not contact the driving block 17, the moving block 13 can be driven to displace by the compression spring 15.

[0027] Moreover, a limiting groove 18 is opened inside the driving block 17, and the driving block 17 is connected to the moving block 13 through the limiting groove 18. A telescopic cylinder is provided outside the moving rod 16, and the driving end of the telescopic cylinder is fixedly connected to the moving rod 16. When the telescopic cylinder is started, it drives the moving rod 16 to displace, so that the driving block 17 displaces to drive the moving block 13 to displace. The moving block 13 can be limited through the limiting groove 18. When the moving block 13 displaces, it can drive the delivery groove 14 to displace, and connect the delivery groove 14 to one of the two through slots 12, so that the delivery pipe 10 and the return pipe 11 can be connected to the heating chamber 8 or the cooling chamber 9, enabling the liquid inside the heating chamber 8 or the cooling chamber 9 to be introduced into the inside of the temperature control pipe 5.

[0028] Furthermore, a semiconductor refrigeration sheet 19 is provided inside the fixed shell 4 and between the cooling chamber 9 and the heating chamber 8.

At this time, the conveying grooves 14 inside the two moving blocks 13 are both connected to the heating chamber 8, so that the conveying pipe 10 and the return pipe 11 can be connected to the heating chamber 8. The circulation pump is started to introduce the heated liquid into the interior of the temperature control pipe 5. The guiding fan 7 is started to cooperate with the heat dissipation blocks 6 to conduct the heat into the interior of the connecting frame 2, and cooperate with the heating plate to heat the preform, so as to improve the forming efficiency of the preform. When the preform is formed and needs to be cooled, the telescopic cylinder is started to drive the moving rod 16 to displace, so that the driving block 17 displaces to drive the moving block 13 to displace. The moving block 13 can be limited through the limiting groove 18. When the moving block 13 displaces, it can drive the conveying groove 14 to displace and connect the conveying groove 14 to the cooling chamber 9, so that the low-temperature liquid inside the cooling chamber 9 is introduced into the interior of the temperature control pipe 5. The preform is cooled and shaped through the cooperation of the heat dissipation blocks 6 and the guiding fan 7. Through the overall design, the preform can be effectively cooled, and the cooling effect can be effectively increased. Through the return pipe 11, the liquid can be refluxed and introduced into the interior of the cooling chamber 9 or the heating chamber 8 for repeated use. Compared with the existing integrated device, the overall practicability of the integrated device can be improved through the design of the present utility model.
