Description

Technical Field

[0001] This utility model relates to the field of dairy product packaging box processing technology, specifically to an injection mold for dairy product packaging boxes. Background Technology

[0002] Packaging boxes, as the name suggests, are boxes used to package products. They can be classified by material, such as: cardboard boxes, tin boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated boxes, PVC boxes, etc. Dairy products require packaging boxes during production.

[0003] Currently, the most fatal defect in the molding process is air bubbles in plastic products. Once air bubbles form in a product, it not only affects its appearance, but also its overall structure and strength. Therefore, most products with air bubble defects are scrapped, wasting resources.

[0004] As disclosed in Chinese Patent CN210211180U, an injection mold for packaging boxes includes an upper mold, an upper template, a lower mold, a mold cavity, a base, and upper and lower mold fixing posts. The upper mold is connected to the upper template, and the upper template is provided with an injection port. A mold cavity is formed between the upper mold and the lower mold. The upper and lower mold fixing posts are set on the base, and the upper template passes through the upper and lower mold fixing posts. The upper template moves up and down along the upper and lower mold fixing posts. A flow channel is also connected to the injection port, and the flow channel is connected to the upper mold cavity. An insert block is also provided in the mold cavity. The insert block is connected and fixed to the lower mold. A negative pressure suction port is provided on the insert block, and a negative pressure pipe is connected to the bottom of the insert block. The lower mold is set on a mold foot, and the mold foot is set on the base. An ejector rod is provided on the lower mold. This device can effectively reduce air bubbles in the material, reduce defects in plastic parts caused by air bubbles, and improve production efficiency.

[0005] However, the lack of a corresponding moving feeding mechanism and a discharge mechanism after injection molding affects production efficiency and makes operation inconvenient.

[0006] To address this issue, we propose an injection mold for dairy product packaging boxes. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] Example 1: An injection mold for dairy product packaging boxes includes an operating table 1 and a fixed column 3. The fixed column 3 is fixedly installed in the middle of the upper surface of the operating table 1, and a moving mechanism is provided on the upper surface of the operating table 1.

[0027] The moving mechanism includes a mounting groove 301, a drive motor 303, a transmission component 304, and an injection mold body 305. The mounting groove 301 is formed on the upper surface of the fixed column 3. The drive motor 303 is fixedly mounted on one end surface of the fixed column 3. The transmission component 304 is mounted on the inner wall of the mounting groove 301. The injection mold body 305 is fixedly mounted on the upper connection of the transmission component 304. A through hole 302 is formed on one side of the inner wall of the mounting groove 301. One end of the transmission component 304 passes through the through hole 302 and is fixedly connected to the output end of the drive motor 303. By setting up the moving mechanism, the drive motor 303 drives the transmission component 304 to rotate, thereby moving the injection mold body 305 from moving for injection to moving for material discharge after injection is completed, improving the efficiency of injection.

[0028] A support column 2 is fixedly installed on the bottom surface of the operating table 1, and a support base 201 is fixedly installed on the bottom surface of the support column 2. The support columns 2 are symmetrically distributed at the four corners of the bottom surface of the operating table 1.

[0029] The power supply to the drive motor 303 is turned on, causing the drive motor 303 to work and drive the threaded column in the transmission component 304 to rotate. Through thread engagement, the moving block installed on the outer surface of the threaded column drives the injection mold body 305 to move on the outer surface of the threaded column. After the injection mold body 305 moves to below the injection cover plate 310, the injection operation is performed. After the injection is completed, the injection mold body 305 is moved again to perform injection discharge.

[0030] Example 2: Based on Example 1, a lifting unit is provided on one side of the upper surface of the operating table 1. The lifting unit includes an L-fixed plate 306, a round hole 307, a cylinder 308, a lifting column 309, an injection molded cover plate 310, and an injection molded cylinder 311. The L-fixed plate 306 is fixedly installed on the upper surface of the operating table 1. The round hole 307 penetrates the upper surface of the L-fixed plate 306. The cylinder 308 is fixedly installed on the upper surface of the L-fixed plate 306. The lifting column 309 is installed at the output end of the cylinder 308. The injection molded cover plate 310 is fixedly installed on the bottom surface of the lifting column 309. The injection molded cylinder 311 is fixedly installed on the upper surface of the injection molded cover plate 310. A square groove is opened on the bottom surface of the injection molded cover plate 310. A hole is penetrated in the middle of the upper surface of the injection molded cover plate 310. The injection molded cylinder 311 is fixedly installed on the inner wall of the hole penetrated in the middle of the upper surface of the injection molded cover plate 310.

[0031] A cooling unit is provided on one side of the upper surface of the operating table 1. The cooling unit includes a concave seat 312, a fan slot 313, and a cooling fan 314. The concave seat 312 is fixedly installed on one side of the upper surface of the operating table 1. The fan slot 313 passes through the upper surface of the concave seat 312. The cooling fan 314 is fixedly installed on the inner wall of the fan slot 313. The fan slots 313 are distributed at equal intervals on the upper surface of the concave seat 312. The cooling fan 314 is electrically connected to an external power supply. By setting up the cooling unit, when the injection mold body 305 moves under the cooling fan 314 after injection molding, the cooling fan 314 is connected to an external power supply and rotates to cool the injection mold, making it easier to remove the material.

[0032] After the injection mold body 305 moves below the injection cover plate 310, the cylinder 308 works to push the lifting column 309 down, causing the injection cover plate 310 to descend and engage with the upper surface of the injection mold body 305. Then, the injection is performed into the injection mold body 305 through the injection cylinder 311. After the injection is completed, the threaded column in the transmission component 304 rotates under the drive of the drive motor 303, causing the moving block installed on the outer surface of the threaded column to move the injection mold body 305 to move and discharge the material to below the cooling fan 314. The cooling fan 314 is connected to an external power supply and powered on, causing the cooling fan 314 to rotate and cool the packaging box inside the injection mold body 305 for material discharge.
