[0092] Figure 2A schematic diagram showing the structure of a forming assembly of a labyrinth forming device for a refrigerator enclosure end portion according to an embodiment of the present invention; Figure 3 Another schematic structural diagram of a forming assembly of a labyrinth forming device for a refrigerator enclosure end portion according to an embodiment of the present invention is shown; Figure 4 The present invention is shown Figure 3 Left view (without upper mold frame); Figure 5 The upper mold frame structure schematic diagram of the present invention is shown; please refer to Figure 2-5 In this embodiment, the forming assembly includes an upper mold frame 2, a lower mold frame 3, a pressing cylinder 4, a mold strip fixing plate 5, an upper forming mold strip 6, an upper pressing mold strip 8, a mold strip driving assembly 9, a lower mold strip 10, a vertical moving servo assembly 12, a horizontal moving servo assembly 13 and a bending mold strip 14.

[0093] The lower mold frame 3 is arranged at the bottom of the upper mold frame 2, the pressing oil cylinder 4 is arranged at the top of the upper mold frame 2, and its output end penetrates and extends to the inside of the upper mold frame 2, and the mold strip fixing plate 5 is arranged at the output end of the pressing oil cylinder 4. Specifically, the bottom of the pressing oil cylinder 4 is connected with an inverted T-shaped connection block 21, and the top of the mold strip fixing plate 5 is provided with a clamping groove 22 adapted to the inverted T-shaped connection block 21, and the pressing oil cylinder 4 and the mold strip fixing plate 5 are connected by the inverted T-shaped connection block 21 being clamped in the clamping groove 22. The bottom of the side of the mold strip fixing plate 5 is provided with a positioning pin 23 for positioning the upper molding mold strip 6 and the upper pressing mold strip 8, which can prevent the upper molding mold strip 6 and the upper pressing mold strip 8 from deflecting during the molding process.

[0094] The upper forming mold strip 6 is arranged at the bottom of the mold strip fixing plate 5, and a protrusion 7 is arranged at the bottom of the upper forming mold strip 6, which is used for extruding the end of the refrigerator. The upper pressing mold strip 8 is arranged at the bottom of the mold strip fixing plate 5, and is used to position the end of the refrigerator enclosure close to the end. The mold strip driving component 9 is arranged at the top of the mold strip fixing plate 5, and is used to drive the upper forming mold strip 6 to press down the end of the refrigerator enclosure. The lower mold strip 10 is fixedly connected to the top of the lower mold frame 3, and the top of the lower mold strip 10 is provided with a groove 11 adapted to the protrusion 7. The vertical moving servo component 12 is arranged on the outer side of the lower mold frame 3, and the horizontal moving servo component 13 is arranged on the vertical moving servo component 12. The vertical moving servo component 12 drives the horizontal moving servo component 13 to move in the vertical direction. The bending mold strip 14 is arranged at the output end of the horizontal moving servo component 13, and the bending mold strip 14 is adjusted by the vertical moving servo component 12 and the horizontal moving servo component 13 to bend the end of the refrigerator enclosure after extrusion.

[0095] When the refrigerator enclosure is bent and formed, the end of the refrigerator enclosure that does not need to be formed is first pressed and positioned by the pressing component 16, and then the mold bar fixing plate 5 is pressed down by the pressing oil cylinder 4. The mold bar fixing plate 5 presses the formed end of the refrigerator enclosure through the upper pressing mold bar 8 and the lower mold bar 10, and then the upper forming mold bar 6 is driven by the mold bar driving component 9 to press the refrigerator enclosure downward, so that the protrusion 7 is pressed into the inside of the groove 11, so that the formed end of the enclosure forms a first bending portion similar to a hook shape, such as Figure 11-12 As shown, this is an extrusion molding process.

[0096] After extrusion molding, the pressing cylinder 4 and the die strip driving assembly 9 are lifted and separated from the enclosure, and then the power assembly 15 drives the molding assembly to move right to the first positioning position, so that the first bending portion exceeds the lower die strip 10 and is opposite to the bending die strip 14, and then the pressing cylinder 4 presses down to fix the enclosure, and the bending die strip 14 and the lower die strip 10 are respectively provided with operating bevels adapted to fold the enclosure into an R shape. The vertically moving servo assembly 12 pulls down the bending die strip 14, and the enclosure is bent downward again through the bevel on the bending die strip 14. After being vertical, the bending die strip 14 is driven to move toward the bevel of the lower die strip 10 through the horizontally moving servo assembly 13, so that the vertical edge bent again fits with the bevel of the lower die strip 10 to form a second bending portion, such as Figure 13-14 shown.

[0097] Then the pressing cylinder 4 is raised, the horizontal moving servo assembly 13 returns to its position, and the power assembly 15 pushes the forming assembly to the right to the second positioning position, so that the refrigerator enclosure can form a third bending portion, and then the pressing cylinder 4 presses down to fix the enclosure, and adjusts the position of the bending mold strip 14 so that the protrusion of the bevel of the bending mold strip 14 is inserted into the recess of the first bending portion, and then the vertical moving servo assembly 12 moves upward, so that the third bending portion bends upward. When the third bending portion is at an angle with the horizontal direction (such as Figure 15-16 As shown in FIG. 1 ), the horizontal servo assembly 13 contracts to make the bending mold strip 14 disengage from the notch of the first bending portion. After disengagement, the position of the bending mold strip 14 is adjusted by the horizontal servo assembly 13 and the vertical servo assembly 12 so that the bending mold strip 14 supports the flange of the first bending portion, and then the vertical servo assembly 12 moves upward to make the third bending portion perpendicular to the horizontal plane (as shown in FIG. Figure 17-18 shown).

[0098] Finally, the bending mold strip 14 is pulled out by the horizontal moving servo assembly 13, and the position of the bending mold strip 14 is further adjusted so that the protrusion of the bevel of the bending mold strip 14 is against the second bending part, and the bending mold strip 14 is driven to move to the lower right by the horizontal moving servo assembly 13 and the vertical moving servo assembly 12, so that the hook of the first bending part is horizontal and the second bending part is vertical, and finally a refrigerator enclosure with an R-shaped cross-section (such as Figure 19-20In addition, an adjustment mold bar is provided on the side of the upper pressing mold bar 8 for adjusting the bending angle of the end portion, which can abut against the vertical edge of the third bending portion to prevent the third bending portion from deflecting to the right after being vertical when the bending mold bar 14 is pressed to the right.

[0099] The molding device further includes a moving frame 17, which is slidably connected to the lower mold frame 3 via a vertical slide rail 18 vertically arranged on the lower mold frame 3, and the vertical moving servo assembly 12 drives the moving frame 17 to move in the vertical direction, and the horizontal moving servo assembly 13 is arranged on the moving frame 17. That is to say, during adjustment, the vertical moving servo assembly 12 drives the moving frame 17 to move, thereby driving the horizontal moving servo assembly 13 to move in the vertical direction.
