Technical Field

[0001] This utility model application relates to the field of trim trim trim removal technology, specifically a trim trim removal device for the parting surface of the refrigerator door trim. Background Technology

[0002] As an important component of the refrigerator's exterior, the molding quality of the lower door trim directly affects the product's aesthetics and sealing performance. During the injection molding process, factors such as mold parting line clearance, material flowability, and insufficient mold closing pressure can easily lead to flash (overflow, burrs) at the parting line. These flashes not only disrupt the continuity of the trim surface and increase the risk of leakage, but also reduce the fatigue life of dynamic seals, resulting in an increased failure rate in the assembly process.

[0003] The surface structure of the refrigerator door trim is complex, making it difficult to achieve a good fixation effect using traditional methods. This means that every time the trim is processed and the burrs are trimmed, a repositioning operation is required, which cannot meet the needs of large-scale, high-efficiency production. Utility Model Content

[0014] The advantages of this utility model application compared to the prior art are:

[0015] This application proposes a trim trim trimming device. Its core design utilizes the coordinated action of a support base, a first positioning mechanism, and a second positioning mechanism to position the trim, thereby facilitating the trimming trimming operation with a trimming mechanism. Specifically, the support base has an "L"-shaped cross-section, allowing its sides to closely fit the sides of the trim, providing a stable support base. Two first telescopic drive members drive two first clamping blocks to move towards the center of the support base, achieving initial horizontal positioning of the trim. Simultaneously, a second telescopic drive member moves the second clamping blocks, further constraining the trim in the vertical direction, ensuring each trim is positioned at the center of the support base, guaranteeing consistent trim positioning. During the trimming trimming stage, the trimming wheel in the trimming mechanism contacts the trim surface. Through the coordinated action of the first, second, and third moving mechanisms, the trimming wheel can move three-dimensionally along the trim surface, achieving omnidirectional trimming trimming. This ensures the trimming wheel closely fits the trim surface, achieving efficient trimming trimming. Attached Figure Description

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-6 As shown, this utility model application provides a device for cutting the burr on the parting surface of the lower trim strip of a refrigerator door, including: a fixed frame 1, a connecting frame 2, which is disposed on the back of the fixed frame 1; a cutting component 3, which is disposed on the connecting frame 2 and can reciprocate on the connecting frame 2; and a clamping component 4, which is disposed on the top of the fixed frame 1 and fixes the trim strip; the clamping component 4 includes a support base 41 installed at the center of the top of the fixed frame 1, and the cross-section of the support base 41 is "L" shaped, and the side of the trim strip can be attached to the side of the support base 41. The clamping component 4 also includes a first positioning mechanism 42 disposed at both ends of the support base 41 and used to fix the two end faces of the trim strip. The clamping component 4 also includes a second positioning mechanism 43 disposed at the front of the support base 41 and capable of pressing the side of the trim strip onto the side of the support base 41.

[0025] When operating the refrigerator door trim parting surface flash removal device, firstly, place the refrigerator door trim on the support base 41, ensuring the side of the trim is flush against the side of the support base 41 for initial positioning. Then, use the first positioning mechanism 42 to fix both ends of the trim to prevent horizontal movement. Next, use the second positioning mechanism 43 to press the side of the trim firmly against the side of the support base 41, ensuring the trim does not wobble vertically. At this point, the trim is securely fixed to the clamping assembly 4. Afterward, activate the cutting assembly 3, which reciprocates on the connecting frame 2. Adjust the position of the cutting assembly 3 according to the position of the flash on the trim to remove the flash from the parting surface, ultimately completing the flash removal work on the refrigerator door trim parting surface.

[0026] The first positioning mechanism 42 includes two first telescopic drive members 421 respectively disposed at both ends of the support base 41, and the output end of the first telescopic drive member 421 is also provided with a first clamping block 422 that can cooperate with the two ends of the trim strip.

[0027] When it is necessary to fix the trim strip, the first telescopic drive member 421 is retracted, pulling the first clamping block 422 closer to the two end faces of the trim strip. As the first telescopic drive member 421 continues to move, the first clamping block 422 gradually contacts and applies pressure to the two end faces of the trim strip, eventually clamping the two end faces of the trim strip tightly, restricting the horizontal movement of the trim strip, and providing stable positioning for subsequent trim removal. After the trim removal is completed, the first telescopic drive member 421 is extended, moving the first clamping block 422 away from the two end faces of the trim strip, releasing the clamp on the trim strip, so that the processed trim strip can be removed.

[0028] The second positioning mechanism 43 includes a second clamping block 432 that can reciprocate along the width direction of the support base 41 and press the side of the trim strip onto the side of the support base 41. The second positioning mechanism 43 also includes a second telescopic drive member 431 disposed at the bottom of the support base 41, and the output end of the second telescopic drive member 431 is connected to the second clamping block 432.

[0029] The second telescopic drive 431 is activated. The output end of the second telescopic drive 431 retracts, pushing the second clamping block 432 connected to it to move along the width direction of the support base 41 toward the side of the trim strip. As the second clamping block 432 gets closer, it eventually contacts the side of the trim strip and applies pressure, pressing the side of the trim strip tightly against the side of the support base 41, thereby restricting the movement of the trim strip in the direction perpendicular to the side of the support base 41. After the burr removal is completed, the output end of the second telescopic drive 431 is extended, driving the second clamping block 432 away from the side of the trim strip, releasing the pressure on the trim strip so that the processed trim strip can be removed.

[0030] The cutting assembly 3 includes a cutting mechanism 34 that can move up and down and reciprocate along the width and length directions of the support base 41. The cutting mechanism 34 includes a sliding plate 334 that can move up and down, and a fourth rotary drive member 341 is fixed to the front of the sliding plate 334. The output end of the fourth rotary drive member 341 is connected to a connecting rod 342. The cutting mechanism 34 includes a cutting wheel 345 that is disposed at the bottom of the connecting rod 342 and detachably connected to the connecting rod 342. The cutting mechanism 34 includes a conical buckle 343 that is disposed at the bottom of the connecting rod 342 and can clamp the cutting wheel 345. A fixing nut 344 is also threadedly connected to the upper part of the connecting rod 342, which can cause the conical buckle 343 to retract toward its center and clamp the cutting wheel 345.

[0031] After the trim strip is secured by the clamping assembly 4, the cutting wheel 345 is moved to the location of the flash according to its position. Next, the fourth rotary drive 341 is activated. The output end of the fourth rotary drive 341 drives the connecting rod 342 to rotate, which in turn causes the cutting wheel 345 at the bottom of the connecting rod 342 to rotate at high speed. The high-speed rotating cutting wheel 345 contacts the flash and cuts it off from the trim strip through a cutting action. When the cutting wheel 345 needs to be replaced due to wear from prolonged use, simply rotate the fixing nut 344 to move it upwards along the connecting rod 342, releasing the pressure on the conical clip 343. The conical clip 343 will then loosen, allowing the old cutting wheel 345 to be removed and replaced with a new one. Then, rotate the fixing nut 344 in the opposite direction to re-clamp the new cutting wheel 345 with the conical clip 343, allowing the flash removal work to continue.

[0032] The cutting assembly 3 includes a third moving mechanism 33 that can drive the cutting mechanism 34 to move up and down. The third moving mechanism 33 includes a second support plate 331. A second lead screw 332 is vertically rotatably mounted on the second support plate 331 and is threadedly connected to the sliding plate 334. A third rotary drive member 333 that can drive the second lead screw 332 to rotate is also provided on the top of the second support plate 331. A slide rod for guiding the sliding plate 334 is also provided on the second support plate 331. The cutting assembly 3 includes a second moving mechanism 32 that can drive the third moving mechanism 33 and the cutting mechanism 34 to reciprocate along the width direction of the support base 41. The second moving mechanism 32 includes a first support plate 321. A first lead screw 322 is laterally arranged on the first support plate 321, and the first lead screw 322 is movably connected to the second support plate 331 by a thread. A second rotary drive member 323 that can drive the first lead screw 322 to rotate is also provided on the first support plate 321. A slide rod that can guide the second support plate 331 is provided on the first support plate 321. The cutting assembly 3 includes a first moving mechanism 31 disposed on the top of the connecting frame 2 and capable of reciprocating the second moving mechanism 32, the third moving mechanism 33 and the cutting mechanism 34 along the length direction of the support base 41. The first moving mechanism 31 includes a rotatable synchronous wheel 312 disposed on the top of the connecting frame 2 and a belt disposed between the synchronous wheels 312. The first moving mechanism 31 also includes a slide rail 311 disposed on the connecting frame 2 and slidably connected to the first support plate 321. The first moving mechanism 31 includes a first rotary drive member 313 disposed on the connecting frame 2 and capable of driving the synchronous wheel 312 to rotate.

[0033] When it is necessary to adjust the position of the cutting assembly 3 along the length of the support base 41, the first rotary drive 313 is activated, which drives the synchronous pulley 312 to rotate. The synchronous pulley 312 drives the belt to move, and the belt drives the first support plate 321 to slide along the slide rail 311. The second rotary drive 323 is activated, which drives the first lead screw 322 to rotate. Since the first lead screw 322 is threadedly connected to the second support plate 331, and the second support plate 331 is guided by the slide rod, it will move along the axial direction of the first lead screw 322. The third rotary drive 333 is activated, which drives the second lead screw 332 to rotate. Since the second lead screw 332 is threadedly connected to the sliding plate 334, and the sliding plate 334 is guided by the slide rod, it will move up and down along the axial direction of the second lead screw 332, thereby driving the cutting mechanism 34 to move up and down, so that the cutting wheel 345 reaches the appropriate height position. When the cutting mechanism 34 moves to the appropriate position, the fourth rotary drive 341 is activated. The fourth rotary drive 341 drives the connecting rod 342 to rotate, which in turn causes the cutting wheel 345 at the bottom of the connecting rod 342 to rotate at high speed. The high-speed rotating cutting wheel 345 contacts the flash and cuts the flash off the trim strip through cutting action.

[0034] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
