Description

Technical Field

[0001] This utility model belongs to the field of injection molding technology, specifically relating to an automatic cut-off device for the gate of a refrigerator long trim strip. Background Technology

[0002] In the injection mold production process, different gate designs are usually required based on the product's appearance requirements. The gate is attached to the molded part after molding, necessitating manual shearing to separate the part from the gate. This not only reduces production efficiency and increases production costs but also affects the product's surface quality. Currently, for specific materials with a certain degree of compressibility, existing automatic cutting mechanisms suffer from complex structures, hindering processing and assembly. Mold opening and closing between plates relies on nylon openers and closers, but these are not wear-resistant, not heat-resistant, and have limited usability, making them unsuitable for mass production.

The outer sides of the left and right placement platforms are provided with a fixing mechanism. The bottom of the left and right placement platforms is provided with a cutting mechanism for cutting the gate.

[0005] Preferably, the fixing mechanism includes a rotary pressing cylinder disposed on the outside of the placement platform, and a fixing block is provided at the output end of the rotary pressing cylinder.

[0006] Preferably, the shearing mechanism includes a first cylinder disposed at the bottom of the workbench, the output end of the first cylinder being connected to a mounting plate, and an electric cutting shear being disposed opposite to the mounting plate.

[0007] Preferably, the adjustment mechanism includes a second cylinder and a fixed push plate respectively disposed at the bottom of the left and right placement platforms, and the output end of the second cylinder is fixedly connected to the fixed push plate.

[0008] Preferably, the worktable is provided with a slide rail, and the bottom of the left and right placement platforms is provided with sliders that match the slide rail.

[0009] Preferably, positioning blocks for locating and cutting the gate of the refrigerator trim strip are provided on both sides above the slide rail.

[0010] Preferably, the left and right placement platforms are provided with clearance openings for avoiding the electric cutting shears.

[0011] Preferably, the clearance opening is located directly below the gate of the refrigerator trim strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the adjustment mechanism and the fixing mechanism fix the refrigerator long trim strip in place, and the cutting mechanism automatically cuts off the gate of the refrigerator long trim strip, thereby realizing the automated production of the refrigerator long trim strip, improving production efficiency and reducing the labor intensity of workers.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0023] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the automatic gate cutting device for refrigerator long trim strips includes a worktable 1. The worktable 1 is provided with a left placement platform 2 and a right placement platform 3 for placing the left and right refrigerator long trim strips respectively. The bottom of the left placement platform 2 and the right placement platform 3 is provided with an adjustment mechanism 4 for adjusting the distance between the left placement platform 2 and the right placement platform 3. The outer side of the left placement platform 2 and the right placement platform 3 is provided with a fixing mechanism 5. The bottom of the left placement platform 2 and the right placement platform 3 is provided with a cutting mechanism 6 for cutting the gate.

[0024] This utility model proposes an automatic cutting device for the gate of long decorative strips in refrigerators. The worktable 1 serves as the basic support platform for the entire automatic cutting device for long decorative strips in refrigerators, providing a stable working reference surface for the entire device.

[0025] The left placement platform 2 is set on the workbench 1 and is specifically used to place the long refrigerator trim strip on the left side, providing a stable placement position for subsequent operations such as gate cutting.

[0026] The right placement platform 3 is also set on the workbench 1, opposite to the left placement platform 2, and is used to place the refrigerator trim strip on the right side. Together with the left placement platform 2, it can place the refrigerator trim strips on the left and right sides simultaneously or separately to meet different production needs.

[0027] Adjustment mechanism 4 is installed at the bottom of the left placement platform 2 and the right placement platform 3. It is used to adjust the distance between the left placement platform 2 and the right placement platform 3. Since the length of the long trim strips of different refrigerator models may vary, the distance between the two placement platforms can be flexibly adjusted by adjustment mechanism 4 to accommodate the placement needs of trim strips of different sizes, thereby improving the versatility of the device.

[0028] The fixing mechanism 5 is respectively installed on the outer side of the left placement platform 2 and the right placement platform 3. After the refrigerator trim strip is placed on the placement platform, the fixing mechanism 5 can fix the trim strip to prevent it from moving or shaking during the subsequent gate cutting process, ensuring the accuracy and stability of the cutting operation and improving product quality.

[0029] The shearing mechanism 6 is located below the left placement platform 2 and the right placement platform 3. It is used to cut off the gate of the refrigerator trim strip placed on the placement platform.

[0030] Based on the size of the refrigerator trim strip to be processed, the distance between the left placement platform 2 and the right placement platform 3 is adjusted by the adjustment mechanism 4 so that the distance between the left placement platform 2 and the right placement platform 3 is suitable for placing the trim strip of that size.

[0031] Place the long refrigerator trim strips on the left and right sides onto the left and right placement platforms 2 and 3 respectively, ensuring the strips are stable. Activate the fixing mechanism 5 to secure the placed refrigerator trim strips from the outside of the left and right placement platforms 2 and 3, preventing them from moving during subsequent operations.

[0032] The shearing mechanism 6 is activated, and it cuts off the gate portion of the refrigerator trim from below the placement platform. Thanks to the support of the left and right placement platforms 2 and 3, and the fixation of the trim by the fixing mechanism 5, the shearing mechanism 6 can accurately and stably complete the gate removal operation.

[0033] After the gate is removed, close the shearing mechanism 6, loosen the fixing mechanism 5, and take out the processed refrigerator trim strip to proceed to the next round of processing.

[0034] The automatic gate cutting device for long decorative strips in refrigerators can efficiently and accurately cut off the gates of long decorative strips in refrigerators, thereby improving production efficiency and product quality.

[0035] Combination Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the fixing mechanism 5 includes a rotary pressing cylinder 51 disposed on the outside of the placement platform 2, and a fixing block 52 is provided at the output end of the rotary pressing cylinder 51.

[0036] Specifically, the rotary pressing cylinder 51, as the core power component of the fixing mechanism 5, is located on the outside of the placement platform 2. The fixing block 52 is installed at the output end of the rotary pressing cylinder 51. The fixing block 52 directly contacts the long refrigerator trim strip, serving a fixing function. It ensures sufficient pressure is applied to the trim strip during the fixing process to prevent movement. The shape and size of the fixing block 52 are designed according to the shape of the long refrigerator trim strip and the fixing requirements to better fit the surface of the trim strip and achieve a stable fixing effect.

[0037] Before the refrigerator trim strip is secured, the rotating cylinder 51 is in its initial position. At this time, the fixing block 52 is away from the trim strip on the left and right placement platforms 2 and 3, and is in a raised and non-rotated state, providing space for the trim strip to be placed. Place the refrigerator trim strip on the left and right placement platforms 2 and 3, ensuring that the trim strip is placed accurately.

[0038] After the trim strip is placed, the rotating pressing cylinder 51 drives the fixing block 52 to rotate, positioning it to the desired location where the long refrigerator trim strip needs to be fixed. Once in position, the rotating pressing cylinder 51 continues to drive the fixing block 52 downwards, gradually approaching and finally pressing it onto the long refrigerator trim strip. By applying pressure, the trim strip is firmly fixed to the placement table 2, preventing movement or wobbling during subsequent operations such as gate removal, ensuring processing accuracy and stability.

[0039] After the processing is completed, the rotating pressing cylinder 51 stops rotating and moves in the opposite direction, causing the fixed pressing block 52 to lift up first, and then rotate in the opposite direction back to the initial position, preparing for the next fixing and processing of the trim strip.

[0040] Combination Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the shearing mechanism 6 includes a first cylinder 61 disposed at the bottom of the workbench 1. The output end of the first cylinder 61 is connected to a mounting plate 62, and an electric cutting shear 63 is disposed opposite to the mounting plate 62.

[0041] Specifically, the first cylinder 61 is installed at the bottom of the worktable 1. The mounting plate 62 is connected to the output end of the first cylinder 61. The mounting plate 62 provides a mounting platform for the electric cutting shears 63, ensuring that the electric cutting shears 63 can be stably and accurately installed in a suitable position and can move up and down with the movement of the first cylinder 61. The mounting plate 62 may be provided with mounting holes or slots to facilitate the installation and fixation of the electric cutting shears 63.

[0042] The electric cutting shears 63 are positioned opposite each other above the mounting plate 62. The electric cutting shears 63 are electrically driven cutting tools. A motor powers the entire cutting shear, and a transmission mechanism (such as gears or chains) converts the motor's rotational motion into the opening and closing motion of the cutting blades, thereby achieving the removal of the gate. The two opposing electric cutting shears 63 can simultaneously cut the gates on both sides of the refrigerator trim strip placed on the left and right mounting platforms 2 and 3, improving cutting efficiency.

[0043] When the gate cutting operation is not performed, the first cylinder 61 is in the initial position. At this time, the mounting plate 62 and the electric cutting shear 63 are located at a lower position at the bottom of the worktable 1, away from the two left and right refrigerator trim strips placed on the left and right placement platforms 2 and 3, providing space for the placement and fixing of the trim strips.

[0044] Once the refrigerator trim strips are placed and secured, the first cylinder 61 moves upward, causing the mounting plate 62 to move upward as well. As the mounting plate 62 rises, the electric cutting shears 63 also rise, gradually approaching the gate areas of the two refrigerator trim strips placed on the left and right placement platforms 2 and 3, respectively.

[0045] Once the electric cutting shears 63 rises to the appropriate position and aligns with the gate area, the motor of the electric cutting shears 63 is activated. The motor drives the cutting blades to open and close via a transmission mechanism, cutting off the gates of the two refrigerator trim strips on the left and right sides.

[0046] After the gate is removed, the motor of the electric cutting shear 63 is stopped, and at the same time the first cylinder 61 moves downward, driving the mounting plate 62 and the electric cutting shear 63 back to the initial position, preparing for the next gate removal operation.

[0047] Combination Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the adjustment mechanism 4 includes a second cylinder 41 and a fixed push plate 42 respectively disposed at the bottom of the left placement platform 2 and the right placement platform 3. The output end of the second cylinder 41 is fixedly connected to the fixed push plate.

[0048] Specifically, the second cylinder 41 is located at the bottom of the left placement platform 2 and is the power drive component of the adjustment mechanism 4. It is a pneumatic actuator that can convert the energy of compressed air into mechanical linear motion.

[0049] The fixed push plate 42 is located on one side of the right placement platform 3. The fixed push plate 42 is a flat plate structure with a certain strength and rigidity, usually made of metal materials, such as steel or aluminum alloy, to ensure that it can stably bear and transmit force during the adjustment process. As a force-bearing support and transmission component at the output end of the second cylinder 41, it converts the linear motion of the second cylinder 41 into a pushing force on the left placement platform 2, thereby realizing the adjustment of the distance between the left placement platform 2 and the right placement platform 3.

[0050] Combination Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, a slide rail 7 is provided on the worktable 1, and sliders 8 that match the slide rail 7 are provided at the bottom of the left placement platform 2 and the right placement platform 3.

[0051] Specifically, the slide rail 7 is mounted on the worktable 1 and is a track structure with a certain length and shape. During use, the slide rail 7 can withstand the repeated sliding friction of the slider 8 without being easily damaged. The cross-sectional shape of the slide rail 7 is usually I-shaped, dovetail-shaped, or other shapes suitable for matching the slider 8. Its surface is finely processed to have high flatness and smoothness to reduce the frictional resistance when the slider 8 slides.

[0052] Slider 8 is installed at the bottom of the left placement platform 2 and the right placement platform 3. The number of sliders is determined according to factors such as the size and weight of the placement platforms. Generally, at least two sliders 8 are installed at the bottom of the left placement platform 2 and the right placement platform 3 to ensure the stability of the sliding. The shape and size of the slider 8 match the slide rail 7, so that it can be tightly embedded in the slide rail 7 to achieve smooth sliding.

[0053] Combination Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, positioning blocks 71 are provided on both sides above the slide rail 7 for positioning and cutting the gate of the refrigerator long trim strip.

[0054] Specifically, positioning blocks 71 are positioned on both sides above the slide rail 7. This allows the positioning blocks 71 to position the trim strip when the left placement platform 2 and the right placement platform 3 (where the refrigerator trim strip is placed) move along the slide rail 7 to the appropriate position, facilitating subsequent cutting of the refrigerator trim strip's gate.

[0055] Positioning blocks 71 are installed on both sides above the slide rail 7 by bolts, welding, or other suitable fixing methods. When the left placement platform 2 and the right placement platform 3 move to the position of positioning blocks 71, positioning blocks 71 block the slider 8. At this time, the electric cutting shears 63 are positioned below the gate of the refrigerator long trim that needs to be cut.

[0056] Combination Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the left placement platform 2 and the right placement platform 3 are provided with clearance openings 9 for avoiding the electric cutting shears 63.

[0057] Combination Figure 1 , Figure 2 and Figure 3 As shown, the clearance 9 is located directly below the gate of the refrigerator trim strip.

[0058] Specifically, the clearance opening 9 is located on the left placement platform 2 and the right placement platform 3, and its position is determined according to the working position and movement trajectory of the electric cutting shears 63. When the left placement platform 2 and the right placement platform 3 are adjusted to the appropriate position for the refrigerator long trim gate cutting operation, the clearance opening 9 is exactly located below the corresponding position where the electric cutting shears 63 needs to cut the gate.

[0059] The clearance opening 9 ensures that the electric cutting shears 63 can pass smoothly through the clearance opening 9 to cut the gate, while not affecting the support and positioning of the refrigerator trim on the placement platform.
