[0024] Please refer to Figures 1-4The utility model provides a technical scheme: a thin -walled preservation box cover injection mold, including preservation box cover body 1, be used for thin -walled preservation box cover production's injection mold 2, be used for the demoulding of production after mould and take the material and take the material mechanical arm 3 and be located injection mold 2 one side take the material mechanical arm 3 one side downstream for the fixed ear of preservation box cover body 1 fixed ear turnover detection and be used for the detection of fixed ear turnover detection device 4, injection mold 2 includes the pouring assembly 21, cavity 22 and cooling assembly 23 that set gradually from top to bottom, cavity 22 includes upper chamber plate 221 and lower chamber plate 222, and preservation box cover body 1 is pressed together between upper chamber plate 221 and lower chamber plate 222, take the material mechanical arm 3 is located cavity 22 one side, and take the material mechanical arm 3 outer wall is connected with electric displacement guide rail module 31, and electric displacement guide rail module 31 bottom is connected with the support frame 32 that sets up, and take the material mechanical arm 3 output end is connected with the suction cup 33 for taking the material of preservation box cover body 1 in cavity 22, and suction cup 33 with preservation box cover body 1 outer wall activity is attracted, and suction cup 33 is connected with gas supply equipment through high pressure gas pipe, and electric displacement guide rail module 31 is connected with the controller on injection mold 2 through wire electrically.

[0025] It is to be noted that, in the embodiment, the pouring assembly 21 is one of the core parts of the injection mold, used for injecting molten plastic into the cavity, and the pouring assembly includes a sprue, a runner, and a cooling system, etc. In the production of the thin-walled preservation box cover, the pouring assembly ensures that the plastic can uniformly fill the entire cavity while avoiding excessive pressure loss. The cavity 22 is the space for plastic molding, which determines the shape and size of the final product. In the injection mold for the thin-walled preservation box cover, the cavity is usually composed of an upper chamber plate 221 and a lower chamber plate 222, which tightly cooperate to form a complete closed space. When the plastic is injected into the cavity 22, it will cool and solidify inside the cavity 22, forming the basic shape of the preservation box cover. The cooling assembly 23 is used to accelerate the cooling process of the plastic and shorten the production cycle. It includes a cooling water channel circulation system. In the production process of the thin-walled preservation box cover, since the plastic wall is thin, the cooling speed is fast. Therefore, the cooling assembly can ensure uniform cooling of the plastic, reducing deformation and stress concentration.

[0026] When the injection mold completes a production cycle, the mold will open, and the ejector pin will eject the formed cover. At this time, the taking mechanical arm 3 will receive a signal from the controller, preparing to take the cover. The suction cup 33 on the taking mechanical arm will lower to the position of the cover and firmly adsorb the cover on the suction cup through negative pressure adsorption. The suction cup 33 ensures that the cover can be stably taken and held without falling off. After taking the cover, the taking mechanical arm 3 will move to the position of the fixed lug flip detection device 4 along the preset trajectory. In this process, the taking mechanical arm 3 maintains a stable speed and posture to ensure that the cover will not be damaged or deformed during movement. After reaching the detection device, the detection is performed. After the detection is completed, the detection device will feed back the detection result to the taking mechanical arm 3 or the controller. If the detection result is qualified, the taking mechanical arm 3 will continue the next taking cycle. If the detection result is unqualified, the taking mechanical arm will send the unqualified product to the designated waste area.

[0027] Through the cooperation of the injection mold 2, the fixed lug flip detection device 4 and the taking mechanical arm 3, the quality detection efficiency and accuracy of the thin-walled cover fixed lug can be greatly improved. The automatic detection method not only reduces manual intervention and errors, but also improves production efficiency and product quality.

[0028] Please refer to Figure 3 and 4 , the fixed lug flip detection device 4 includes a detection seat 41, and the detection seat 41 is provided with detection racks 42 in a rectangular structure. Each detection rack 42 is fixedly provided with a detection bearing 43, and each detection bearing 43 is provided with a detection wheel 44. When the fixed lug flips, the detection wheels 44 on the four detection racks 42 abut against the fixed lugs on the outer wall of the cover body 1. When detecting, the suction cup 33 on the output end of the taking mechanical arm 3 adsorbs the cover body 1 and moves up and down inside the four detection racks 42. The fixed lugs on the cover body 1 flip back and forth for detection.

[0029] It should be noted that in the present embodiment, the detection bearing 43 is a key component fixed on the detection rack 42, which is used to support and guide the rotating movement of the detection wheel 44. The detection bearing 43 has high precision and low friction characteristics, ensuring that the detection wheel can rotate smoothly and accurately. The detection wheel 44 is directly in contact with the cover fixed lug, which simulates the flip action in the actual use process through rotation. The detection wheel 44 is made of a material with high wear resistance and will not be damaged or deformed during long-term use. At the same time, the surface of the detection wheel 44 is smooth to prevent scratches on the cover fixed lug during detection.

[0030] The suction cup 33 on the taking mechanical arm 3 takes the fresh-keeping box cover body 1 from the inside of the cavity 22, the taking mechanical arm 3 drives the fresh-keeping box cover body 1 to displace to the fixed lug overturning detection device 4 in cooperation with the suction cup 33, the taking mechanical arm 3 drives the fresh-keeping box cover body 1 to move up and down in the four detection racks 42, when the fixed lug on the outer wall of the fresh-keeping box cover body 1 can normally overturn, the fixed lug on the outer wall of the fresh-keeping box cover body 1 abuts against the detection wheel 44 at this time, the detection wheel 44 rolls, the fresh-keeping box cover body 1 passes through the detection rack 42 up and down, when the fixed lug on the outer wall of the fresh-keeping box cover body 1 can normally overturn, the fixed lug on the outer wall of the fresh-keeping box cover body 1 abuts against the detection wheel 44 at this time, the fresh-keeping box cover body 1 cannot pass through the detection rack 42 up and down, and it is explained that the fresh-keeping box cover body 1 overturns difficultly and is a defective product.

[0031] The working process of the utility model is as follows:

[0032] In use, the injection mold 2 is used for injecting molten plastic into a cavity, and after the plastic is injected into the cavity 22, it will be cooled and solidified in the cavity 22 to form the basic shape of the fresh-keeping box cover, and the cooling assembly 23 is used for accelerating the cooling process of the plastic, and after the injection mold completes a production cycle, the mold will be opened, and the ejector pin will eject the formed fresh-keeping box cover, at this time, the taking mechanical arm 3 will receive the signal of the controller and be ready for taking operation, the suction cup 33 on the taking mechanical arm 3 takes the fresh-keeping box cover body 1 from the inside of the cavity 22, the taking mechanical arm 3 drives the fresh-keeping box cover body 1 to displace to the fixed lug overturning detection device 4 in cooperation with the suction cup 33, the taking mechanical arm 3 drives the fresh-keeping box cover body 1 to move up and down in the four detection racks 42, when the fixed lug on the outer wall of the fresh-keeping box cover body 1 can normally overturn, it will abut against the detection wheel 44, the detection wheel will roll, and the fresh-keeping box cover body can smoothly pass through the detection rack, if the fixed lug on the outer wall of the fresh-keeping box cover body 1 cannot normally overturn, it will not abut against the detection wheel, so that the fresh-keeping box cover body 1 cannot pass through the detection rack, at this time, it can be judged that the fixed lug of the fresh-keeping box cover body overturns difficultly and is a defective product, and the taking mechanical arm will send the unqualified product to the designated waste area.

[0033] The utility model is described exemplarily in combination with the drawings, and obviously, the specific implementation of the utility model is not limited by the above mode, as long as the method concept and the technical scheme of the utility model are adopted for this non-essential improvement or the concept and the technical scheme of the utility model are directly applied to other occasions without improvement, and they are all within the protection scope of the utility model.
