Description

Technical Field

[0001] This utility model belongs to the field of mold technology and relates to an injection mold for a storage box with a simulated stitched leather pattern. Background Technology

[0002] In the manufacturing of storage boxes, injection molds are a commonly used production tool. Traditional injection molds for storage boxes produce boxes with a relatively simple appearance, lacking unique textures and feel. As consumers' demands for product appearance increase, storage boxes with simulated leather stitching patterns are becoming increasingly popular in the market. However, existing injection molds are insufficient to meet the needs of producing such storage boxes with special patterns, failing to accurately mold the simulated leather stitching pattern onto the box surface, resulting in poor product quality and aesthetics. Therefore, there is an urgent need to design an injection mold for storage boxes with simulated leather stitching patterns that can overcome these shortcomings.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses an injection mold for a storage box [Application No.: 201821062912.1], which includes a fixed template. A forming groove is opened in the middle of the top of the fixed template. A partition is slidably connected inside the forming groove. Fixed plates are fixed on both sides of the bottom of the partition. Rotating rods are hinged to both sides of the fixed plates. A first motor is installed on one bottom side of the fixed template. A bidirectional threaded rod is fixed to the output shaft of the first motor. Two sets of moving plates are threadedly connected to the bidirectional threaded rod. The bottom of the rotating rod is hinged to one side of the moving plate. Support columns are fixed around the top of the fixed template. Lifting plates are slidably connected to the support columns. Four sets of guide rods are symmetrically fixed to the bottom of the lifting plates. Movable plates are slidably connected to the guide rods. However, this solution still cannot simultaneously form the imitation stitched leather pattern of the storage box during the injection molding process, requiring secondary processing. It has the defects of many processes and low production efficiency. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, an injection mold for a storage box with a simulated stitched leather pattern includes a lower mold 1 and an upper mold 2. An injection molded part 3 is positioned above the upper mold 2. The lower mold 1 contains a box-forming protrusion 4 and a lower rotating shaft forming part 5. The protrusion 4 contains a lower part 6 with a simulated stitched leather pattern. The upper mold 2 contains a box-forming cavity 7 and an upper rotating shaft forming part 8. The protrusion 4 and cavity 7 are positioned and shaped accordingly. The lower rotating shaft forming part 5 and upper rotating shaft forming part 8 are positioned and shaped accordingly. The cavity 7 contains an upper part 9 with a simulated stitched leather pattern. The upper part 9 and lower part 6 are positioned and shaped accordingly. An ejector 10 is positioned below the lower mold 1.

[0027] In this embodiment, during mold closing, the box-forming protrusion 4 is embedded into the box-forming cavity 7, and the two fit together tightly, defining the forming space of the main body of the storage box; the lower part of the rotating shaft forming 5 and the upper part of the rotating shaft forming 8 are correspondingly fitted to form the rotating shaft part of the storage box; at the same time, the upper part of the imitation stitched leather pattern forming 9 and the lower part of the imitation stitched leather pattern forming 6 are fitted to create conditions for forming the imitation stitched leather pattern on the surface of the storage box; the ejector 10 below the lower mold 1 of the storage box forming is responsible for ejecting the formed storage box after injection molding. This structural design allows the mold to integrally form the main body of the storage box, the rotating shaft, and the surface with a unique texture, improving production efficiency, reducing subsequent processing steps, and lowering production costs. At the same time, the precise fit of each component ensures the dimensional accuracy and molding quality of the product.

[0028] Combination Figure 1-4As shown, the lower part 6 of the imitation stitched leather pattern includes a plurality of pattern forming grooves 11 disposed in the box forming protrusion 4, and the pattern forming grooves 11 are disposed opposite to the upper part 9 of the imitation stitched leather pattern.

[0029] Specifically, during the injection molding process, when the upper mold 2 and the lower mold 1 of the storage box are closed, the pattern forming groove 11 and the upper part 9 of the imitation stitched leather pattern are positioned opposite each other. After the plastic is injected into the mold cavity, it fills the gap between the pattern forming groove 11 and the upper part 9 of the imitation stitched leather pattern under pressure, thereby forming the groove part of the imitation stitched leather pattern on the surface of the storage box. The design of the pattern forming groove 11 provides a basis for the precise forming of the imitation stitched leather pattern, so that the surface pattern of the produced storage box has a consistent and clear texture, improving the appearance and market competitiveness of the product.

[0030] The upper part 9 of the imitation stitched leather pattern includes a plurality of imitation stitched leather pattern protrusions 12 disposed in the box forming cavity 7. The imitation stitched leather pattern protrusions 12 correspond to the pattern forming grooves 11 in position and are matched in shape.

[0031] In this embodiment, during injection molding, the imitation stitched leather pattern forming protrusion 12 is embedded into the pattern forming groove 11, and the plastic flows and solidifies between the two to form a textured surface consistent with the imitation stitched leather pattern. The cooperation between the imitation stitched leather pattern forming protrusion 12 and the pattern forming groove 11 ensures a high degree of reproduction of the imitation stitched leather pattern.

[0032] Combination Figure 2 , Figure 4 As shown, the lower part 5 of the rotating shaft forming includes a rotating shaft positioning protrusion 13 and a rotating shaft forming cavity 14 disposed in the lower mold 1 of the storage box forming.

[0033] In this embodiment, during the mold closing process, the rotating shaft positioning protrusion 13 and the rotating shaft forming cavity 14 cooperate with the rotating shaft positioning groove 15 and the rotating shaft forming center protrusion 155 in the upper rotating shaft forming part 8, respectively. The rotating shaft positioning protrusion 13 is inserted into the rotating shaft positioning groove 15 to achieve positioning, ensuring the positional accuracy of the rotating shaft during the forming process. The rotating shaft forming cavity 14 and the rotating shaft forming center protrusion 155 together define the shape of the rotating shaft. Through the design of the rotating shaft positioning protrusion 13 and the rotating shaft forming cavity 14, the accuracy and stability of the rotating shaft forming are improved, ensuring the quality of the rotating parts of the storage box, making the product rotate more smoothly during use, and extending its service life.

[0034] The upper part 8 of the rotating shaft forming includes a rotating shaft positioning groove 15 and a rotating shaft forming middle protrusion 155 disposed in the upper mold 2 of the storage box. The rotating shaft positioning protrusion 13 is arranged opposite to the rotating shaft positioning groove 15, and the rotating shaft forming middle cavity 14 is arranged opposite to the rotating shaft forming middle protrusion 155.

[0035] In this embodiment, during mold closing, the rotating shaft positioning protrusion 13 and the rotating shaft positioning groove 15 are aligned and engaged to achieve precise positioning of the rotating shaft; the rotating shaft forming cavity 14 and the rotating shaft forming center protrusion 155 are aligned and engaged to complete the forming of the rotating shaft; the engagement of the rotating shaft positioning groove 15 and the rotating shaft forming center protrusion 155 with the corresponding components of the rotating shaft forming lower part 5 further ensures the accuracy and reliability of the rotating shaft forming, and improves the overall quality and practicality of the storage box.

[0036] Combination Figure 1 As shown, the injection molded part 3 includes an injection molding main board 16 disposed above the upper mold 2 for forming the storage box.

[0037] In this embodiment, during injection molding, molten plastic enters the mold through the injection main board 16. The injection main board 16 guides the plastic to the upper flow channel 17 inside the upper mold of the receiving box, realizing the initial flow of plastic. The injection main board 16 serves as the entrance for plastic to enter the mold, providing a stable supply of plastic for the injection molding process, ensuring the continuity and uniformity of injection molding, and helping to improve the molding quality of the product.

[0038] The upper mold 2 for forming the storage box has an upper flow channel 17, and the lower mold 1 for forming the storage box has a lower flow channel 18. The upper flow channel 17 is connected to the injection molding main board 16.

[0039] In this embodiment, during injection molding, plastic flows from the injection main board 16 into the upper flow channel 17. After the upper and lower molds are closed, the upper flow channel 17 is connected to the lower flow channel 18, and the plastic continues to flow into the lower flow channel 18, thereby evenly filling various parts of the mold cavity. The design of the flow channel enables the plastic to be evenly distributed to all corners of the mold, avoiding product defects such as material shortage and air bubbles caused by uneven plastic flow, thus improving the molding quality and consistency of the product.

[0040] Combination Figure 1-3 As shown, the ejector 10 includes an ejector fixing plate 19 disposed below the lower mold 1 of the storage box, and the ejector fixing plate 19 is provided with a plurality of ejector rods 20.

[0041] In this embodiment, after injection molding is completed, the ejection device of the injection molding machine pushes the ejection fixing plate 19 upward, and the ejection fixing plate 19 drives the ejection rod 20 to lift upward, ejecting the molded storage box from the lower mold 1 of the storage box. The cooperation between the ejection fixing plate 19 and the ejection rod 20 realizes the rapid demolding of the molded product, improves production efficiency, reduces the dwell time of the product in the mold, and reduces the risk of product deformation.

[0042] Combination Figure 1-3 As shown, a fixed base plate 21 is provided below the ejector fixing plate 19.

[0043] In this embodiment, the fixed base plate 21 serves to support and fix the ejection fixing plate 19, ensuring the stability of the ejection fixing plate 19 during the ejection process, so that it can move smoothly along the predetermined direction. The fixed base plate 21 provides a stable support foundation for the ejection fixing plate 19, ensuring the reliability of the ejection process and avoiding ejection failure or product damage due to shaking or displacement of the ejection fixing plate 19.

[0044] Combination Figure 1-3 As shown, the fixed base plate 21 is provided with two anti-deviation irons 22, and the ejector fixed plate 19 is slidably engaged with the anti-deviation irons 22.

[0045] In this embodiment, during the upward movement of the ejector plate 19, the anti-deviation iron 22 guides and limits it to prevent the ejector plate 19 from shifting during the movement. The anti-deviation iron 22 further improves the accuracy and stability of the ejection process, ensuring that the ejector rod 20 can eject the molded product vertically, avoiding product damage or demolding difficulties due to ejection position deviation, and improving production efficiency and product quality.

[0046] The working principle of this utility model is as follows:

[0047] During injection molding, molten plastic is injected into the upper flow channel 17 through the injection molding main plate 16. After being diverted, the molten plastic enters the lower flow channel 18 and evenly fills the mold cavity formed by the box-shaped protrusion 4 and the box-shaped cavity 7, the lower part of the rotating shaft forming 5 and the upper part of the rotating shaft forming 8, and the upper part of the imitation stitched leather pattern forming 9 and the lower part of the imitation stitched leather pattern forming 6. During the filling process, the molten plastic flows between the imitation stitched leather pattern forming protrusion 12 and the pattern forming groove 11 to form the imitation stitched leather pattern; the rotating shaft is formed between the rotating shaft forming cavity 14 and the rotating shaft forming middle protrusion 155.

[0048] After a certain period of pressure holding and cooling, the storage box is formed. The injection molding machine's moving template drives the upper mold 2 of the storage box to separate from the lower mold 1 of the storage box. Then, the ejection device of the injection molding machine pushes the ejection fixing plate 19 upward, and the ejection rod 20 ejects the formed storage box from the lower mold 1 of the storage box, completing the entire injection molding process.
