Here, the door body 3 of the dishwasher is taken as an example for specific description. The door body 3 of the dishwasher is provided with a mounting groove 31, and the sealing member is mainly a sealing strip 4, which seals the door body 3 of the dishwasher. The pressing tool of the present application needs to press the sealing strip 4 into the mounting groove 31 of the dishwasher to seal the door body 3 of the dishwasher. The sealing strip 4 specifically includes a blade 41, and the blade 41 is connected to a mounting portion 42. When installing, the mounting portion 42 needs to be clamped into the mounting groove 31, so as to achieve the sealing of the door body 3 of the dishwasher.

[0030] like Figure 3 As shown, the door body 3 to be installed is fixedly arranged on the lower mold 2, and support blocks are arranged on opposite sides of the upper surface of the lower mold 2, and positioning pins 22 are arranged on the support blocks. A fixing hole is opened on the side wall of the door body 3, and the positioning pins 22 pass through the fixing hole to fix the door body 3 on the lower mold 2. The lower mold 2 is provided with a groove, and a support plate 21 is arranged in the groove. The support plate 21 is used to increase the supporting force of the lower mold 2 to ensure that the door body 3 will not be scratched or damaged during the production process, and the quality of the produced products is stable and reliable. The material of the support plate 21 is made of brass.

[0031] A guide rail is provided on the operating table 1 , and a slider is provided on the bottom surface of the lower mold 2 . The slider cooperates with the guide rail so that the lower mold 2 slides on the operating table 1 .

[0032] like Figure 6 As shown, the adsorption assembly 53 includes a fixed plate 533, a first cylinder 531 is arranged on the fixed plate 533, guide rods 532 are arranged on both sides of the first cylinder 531, the outer wall of the guide rod 532 is provided with a guide sleeve, the guide sleeve is fixedly connected to the bracket, and the bracket is fixed on the lower mold 2. A plurality of suction cups are arranged on the fixed plate 533, and the suction cups are used to adsorb the seal, so as to adsorb the blade 41 of the seal, so as to prevent the pressing assembly 51 from crushing the blade 41 in the process of pressing the seal.

[0033] The suction cup is an accordion suction cup, and multiple suction cups are arranged on the fixed plate 533 at equal intervals. Multiple suction cups are arranged on one side of the fixed plate 533, and the first cylinder 531 and the guide rod 532 are arranged on the other side of the fixed plate 533, so that the first cylinder 531 drives the suction cup to move.

[0034] like Figure 2 As shown, the first cylinder 531 is connected to an oil pressure structure 6, which is used to provide power for the clamping tooling. The output pressure is stable and can maintain the pressure of the product to prevent the stainless steel from rebounding.

[0035] like Figure 7As shown, the upper mold 5 includes a fixed block, a mounting hole 54 is provided on the fixed block, an elastic element is provided in the mounting hole 54, and the pressing assembly 51 includes a push rod 511, one end of the push rod 511 is connected to the elastic element, so that the push rod 511 extends or retracts into the mounting hole 54. The other end of the push rod 511 is connected to a pressing block 512, which is used to contact the seal and press the mounting portion 42 of the seal into the mounting groove 31.

[0036] A notch is provided on the bottom surface of the pressing block 512 , and the notch is used to match the outer shape of the mounting portion 42 , so that the pressing block 512 and the mounting portion 42 are in close contact.

[0037] A plurality of mating grooves are provided on the pressure block 512, and a plurality of pressure rods 52 are provided on the fixed block. The plurality of pressure rods 52 deform the installation groove 31 provided on the inner door to form a plurality of evenly arranged concave points. The concave points clamp the installation portion 42 of the seal in the installation groove 31, so that the seal does not fall off under normal working conditions.

[0038] like Figure 8 As shown, the pressure rod 52 includes a first rod body 521, the end of the first rod body 521 is fixedly connected to the second rod body 522, and the end of the second rod body 522 is provided with a conical surface 523, so that the conical surface 523 and the installation groove 31 are in contact, and the pressure rod 52 is pressed downward to form a plurality of concave points in the installation groove 31.

[0039] The distance between two adjacent pressure rods 52 is set to 25 mm, and the distance between two adjacent pressure rods 52 is set according to the width of the sealing strip 4, which is not specifically limited here. The angle formed by the conical surface 523 is set to 120° to 150°.

[0040] A second cylinder 531 is disposed on the fixed block, and the second cylinder 531 is used to drive the movement of the pressing assembly 51 .

A start button and an emergency stop button are also arranged on the operating table 1 for controlling the movement of the lower mold 2.

[0042] The working process of the clamping tool provided by the present invention is to sleeve the sealing strip 4 on the door body 3, place the assembled door body 3 on the lower mold 2 for positioning, start the button, and the lower mold 2 moves to the bottom of the upper mold 5 under the drive of the oil pressure structure 6 and stops. The first cylinder 531 drives the suction cup to adsorb the blade 41, and moves the blade 41 upward and away from the suction cup by 3mm to 6mm. The pressing component 51 provided on the upper mold 5 presses down the installation part 42 of the sealing strip 4, and the pressing rod 52 presses the installation groove 31, so that the sealing strip 4 is pressed into the installation groove 31. After completion, the upper mold 5 is reset, and the installed door body 3 is removed.

[0043] The clamping tool provided by the present invention has a logically reasonable entire tooling system. The accordion suction cup is used to ensure that the deformation of the sealing strip 4 will not affect the downward pressing of the lower mold 2. At the same time, the structure is compact, and the sealing strip 4 is tightly pressed by the pressing block 512 to prevent it from deflecting. The sealing strip 4 is pressed into the installation groove 31 by the pressing rod 52.
