[0031] As Figures 1-5As shown in the figure, it shows a rubber plastic insulation pipe uniform foaming device in an embodiment of the present disclosure, including a foaming barrel 1, the inner surface of the foaming barrel 1 is movably connected with a mold 2, the lower surface of the mold 2 is fixedly connected with a sleeve block 3, the bottom end of the sleeve block 3 penetrates through the foaming barrel 1 and extends below the foaming barrel 1, the outer surface of the sleeve block 3 and the inner surface of the foaming barrel 1 are movably connected, the inner surface of the sleeve block 3 movably connects with an insertion block 4, the upper surface of the insertion block 4 and the lower surface of the foaming barrel 1 are movably connected, the lower surface of the foaming barrel 1 is fixedly installed with a first motor 5, the other end of the output shaft of the first motor 5 is fixedly sleeved with a circular shaft 6, the outer surface of the circular shaft 6 is fixedly sleeved with a driving link 7, the other end of the driving link 7 is hinged with a driven link 8, the other end of the driven link 8 is hinged with the lower surface of the insertion block 4.

[0032] When the operator starts the first motor 5, the circular shaft 6 and the driving link 7 will start to rotate, at this time the other end of the driving link 7 will drive the driven link 8, so that the driven link 8 starts to rotate, and the other end of the driven link 8 will drive the insertion block 4 in the process, so that the insertion block 4 starts to move to the right.

[0033] In some examples, the outer surfaces of the front and rear sides of the insertion block 4 are fixedly connected with movable blocks 10, the outer surfaces of the movable blocks 10 are movably connected with guide frames 9, and the upper surfaces of the guide frames 9 are fixedly connected with the lower surface of the foaming barrel 1.

[0034] The design of the guide frame 9 and the movable block 10 plays a limiting role in the moving direction and range of the insertion block 4.

[0035] In some examples, the inner surface of the top of the mold 2 is fixedly connected with a handle 11, and the outer surface of the handle 11 is smooth.

[0046] When the second motor 18 operates, the rotating shaft 19 and the gear 20 will start to rotate.

[0047] In some examples, the outer surface of the gear 20 is meshingly connected with a toothed plate 21, the right surface of the toothed plate 21 is movably connected with the left surface of the mounting plate 17, and the bottom end of the toothed plate 21 is fixedly connected with the left surface of the U-shaped plate 16.

[0048] The rotation of the gear 20 drives the toothed plate 21, so that the toothed plate 21 and the U-shaped plate 16 as a whole start to move upward.

[0049] In some examples, the left surface of the toothed plate 21 is movably connected with an L-shaped limiting block 22 located at the rear side of the gear 20, and the right surface of the L-shaped limiting block 22 is fixedly connected with the left surface of the mounting plate 17.

[0050] The design of the L-shaped limiting block 22 plays a limiting role on the moving direction of the toothed plate 21 and a protection role on the toothed plate 21.

[0051] The working principle and use process of the present disclosure are as follows:

[0052] Firstly, the operator inserts the mold 2 into the middle of the inner surface of the foaming barrel 1 as a whole, and makes the bottom end of the sleeve block 3 pass through the inner surface of the foaming barrel 1 to the lower part of the foaming barrel 1, then the operator starts the No. 1 motor 5, with the operation of the No. 1 motor 5, the circular shaft 6 and the driving link 7 begin to rotate, and the rotation of the driving link 7 drives the driven link 8, thereby making the other end of the driven link 8 drive the plug block 4, so that the plug block 4 begins to move left along the inner surface of the guide frame 9 as a whole, and finally the plug block 4 is inserted into the inner surface of the sleeve block 3, thereby fixing the mold 2 as a whole in the middle of the inner surface of the foaming barrel 1.

[0053] Then the operator puts the rubber plastic insulation pipe on the outer surface of the mold 2, and then the operator starts the microwave generating assembly 14 and the No. 2 motor 18, wherein the operation of the microwave generating assembly 14 makes the microwave generating assembly 14 begin to release microwaves to heat the rubber plastic insulation pipe, and the operation of the No. 2 motor 18 makes the rotating shaft 19 and the gear 20 begin to rotate, and the rotation of the gear 20 drives the toothed plate 21, thereby making the toothed plate 21, the U-shaped plate 16, the telescopic rod 15 and the metal movable ring 13 begin to move up and down as a whole, and finally under the joint action of the microwave generating assembly 14 and the toothed plate 21, the rubber plastic insulation pipe is uniformly heated and foamed, thereby completing the foaming treatment of the rubber plastic insulation pipe.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, not to limit it, although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present disclosure, and they should be covered in the scope of the claims of the present disclosure.
