Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] like Figure 1-5 As shown, the present invention proposes a pickup truck cargo box blister mold, including an installation box 8 with the opening facing upward. The bottom wall of the installation box 8 is connected to the placement plate 22 through a lifting component. A mold 17 is placed in the middle of the upper end of the placement plate 22.
[0032] There are two mounting bottom frames 4, which are located above the opening of the mounting box 8. One end of the mounting bottom frame 4 is hinged to one end of the mounting top frame 5, and the other end of the mounting bottom frame 4 is connected to the other end of the mounting top frame 5 through a latch 6. Opening the latch 6 allows the mounting top frame 5 to be flipped open around the hinge point for easy placement or removal of the blister board. Closing the latch 6 fixes the mounting top frame 5 and the mounting bottom frame 4 together.
[0033] A base plate 12 is installed on the bottom of both sides of the mounting box 8. A side plate 13 is vertically installed on the upper end of the base plate 12 and the end away from the mounting box 8. The two side plates 13 are connected by a sliding component.
[0034] The two mounting bottom frames 4 are connected by multiple connecting blocks 15, and the bottom of each of the two mounting bottom frames 4 is connected to the moving end of the sliding component.
[0035] It also includes a heater 18 with the heating end facing downward and two connecting brackets 2. The heater 18 is located above the mounting lower frame 4 and matches the opening of the mounting box 8 for heating the thermoformed panel. One end of the two connecting brackets 2 is connected to the side of the placement plate 22 through a first opening pre-drilled through the side wall of the mounting box 8, and the other end of the two connecting brackets 2 is connected to the side of the heater 18. When the placement plate 22 is raised or lowered, the heater 18 can be raised or lowered synchronously through the connecting brackets 2 to ensure that the heater 18 always matches the opening of the mounting box 8 and the position of the mold 17 to ensure the heating effect. The mold 17 is made for the pickup truck cargo box liner.
[0036] In this utility model, during the processing and forming of the pickup truck cargo box liner, first open the latch 6, flip open the upper frame 5, place the blister board to be processed between the lower frame 4 and the upper frame 5, then close the upper frame 5 and fasten the latch 6.
[0037] The mounting bottom frame 4 is moved by the sliding component to a suitable working position, and then the mounting bottom frame 4 is fixed by the limiting component.
[0038] Then start the electric push rod 21 to adjust the height of the placement plate 22 and the mold 17. At the same time, the heater 18 is raised and lowered synchronously under the drive of the connecting frame 2. Start the heater 18 to heat the blister board. After the blister board is heated and softened, turn off the heater 18. Then start the electric push rod 21 again to move the mold 17 located above the placement plate 22 upward. At this time, the heater 18 will also rise accordingly.
[0039] When the placement plate 22 moves upward and contacts the bottom of the mounting lower frame 4, the air pump 20 is started to draw air through the vent 23, so that the blister plate is attached to the mold 17 to complete the blister forming, and then it is allowed to cool naturally (it takes about 2 minutes of natural cooling).
[0040] After molding, the limiting component is removed, and then the two connected mounting lower frame 4 are moved along the sliding component by the sliding component, so that the mounting lower frame 4 with the pre-installed blister board on the other side is located at the opening of the mounting box 8, and is limited by the limiting component. The above steps are repeated to blister the blister board, and the pickup truck cargo box liner that has been molded on the mounting lower frame 4 is taken out by opening the latch 6, and then a new blister board is put in for the next processing. The cycle is repeated to improve the utilization rate.
[0041] In an optional embodiment, a limiting plate 11 is installed on the side of the lower frame 4 away from the connecting frame 2, and a limiting component that mates with the limiting plate 11 is installed on the outer wall of the mounting box 8; the limiting component includes a groove block 9 and a butterfly bolt 14; the groove block 9 is installed on the outer end face of the mounting box 8, and the matching limiting plate 11 is located in the groove of the groove block 9, and the butterfly bolt 14 is threaded through the second opening that is pre-penetrated through the outer end of the groove block 9 and the limiting plate 11.
[0042] It should be noted that after the lower frame 4 is moved to the appropriate position, the limiting plate 11 is placed into the groove of the recessed block 9, and the butterfly bolt 14 is tightened to fix the limiting plate 11, thereby limiting the lower frame 4 and preventing it from moving during operation.
[0043] When one of the mounting lower frame 4 contacts one of the side plates 13, the limiting plate 11 on the other mounting lower frame 4 will be matched with the threaded hole pre-drilled in the groove block 9.
[0044] In an optional embodiment, the lifting assembly includes a guide rod 19 and an electric push rod 21. The outer wall of the placement plate 22 is adapted to the inner wall of the mounting box 8, and the middle part of the bottom of the placement plate 22 is connected to the inner bottom wall of the mounting box 8 through the electric push rod 21. There are multiple placement plates 22 arranged in a ring array, and the bottom of the placement plate 22 is connected to the inner bottom wall of the mounting box 8 through the ring array of guide rods 19.
[0045] It should be noted that when the electric push rod 21 is working, it can push the placement plate 22 to move up and down, while the guide rod 19 ensures that the placement plate 22 will not deviate during the lifting and lowering process, making it more stable.
[0046] In an optional embodiment, the upper end of the placement plate 22 is provided with a plurality of ventilation holes 23 communicating with its inner cavity, and the bottom of the placement plate 22 is equipped with an air pump 20 communicating with the inner cavity of the placement plate 22, and the mold 17 is placed on top of the placement plate 22.
[0047] It should be noted that during the vacuum forming process, the air pump 20 works, and air can be drawn out through the vent 23, so that the heated and softened vacuum forming plate is tightly attached to the mold 17 to complete the vacuum forming.
[0048] In an optional embodiment, the sliding assembly includes a slide rod 1 and a slide sleeve 7; the two side plates 13 are connected to each other on opposite sides of the mounting box 8 via the slide rod 1, and the bottom sides of the mounting lower frame 4 are respectively connected to the slide sleeve 7, with the two slide sleeves 7 slidably connected to the outer end faces of the two slide rods 1 respectively.
[0049] It should be noted that when it is necessary to move the lower frame 4, the sliding sleeve 7 can slide on the sliding rod 1, thereby moving the lower frame 4, which is convenient to operate.
[0050] In an optional embodiment, a handle 3 is mounted on the outer side of the upper frame 5 and above the limiting plate 11.
[0051] It should be noted that holding the handle 3 makes it easy to operate the upper frame 5, making it convenient to open and close.
[0052] In an optional embodiment, a breathable mesh 10 extends through the lower part of the plurality of outer end faces of the mounting box 8.
[0053] It should be noted that the breathable mesh 10 allows air to circulate between the inside of the mounting box 8 and the outside air, which helps with air circulation inside the mounting box 8.
[0054] In an optional embodiment, a rubber ring 16 adapted to the bottom of the mounting lower frame 4 is mounted thereon.
[0055] It should be noted that when the placement plate 22 rises and contacts the bottom of the mounting lower frame 4, the rubber ring 16 ensures a tight seal during connection.
[0056] The embodiments of the present invention have been shown and described. It will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
