Technical Field

[0001] This utility model relates to the field of injection molding technology, specifically to an injection mold for processing the left and right hinges of a notebook computer. Background Technology

[0002] With advancements in materials science and the emergence of smaller integrated chips, computers have evolved into laptops that are small, thin, lightweight, and easy to carry. Most current laptops are clamshell designs, typically consisting of a base with the main unit and keyboard, and a top cover with the display screen and lid, all designed to be thin, small, and lightweight. When not in use, the top cover is closed on the base; to use it, the top cover must be flipped up to a suitable angle for easy operation.

[0003] Laptops use hinges to enable opening and closing. In existing technologies, hinges are generally manufactured by die casting, and only one type of hinge can be manufactured at a time. The left and right hinges require different processing equipment, and drilling and other operations are required after processing. The process is cumbersome and the yield rate is low. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an injection mold for processing the left and right hinges of a notebook computer, which can process the left and right hinges in one step, reducing the need for a set of mold designs, reducing manpower input, and lowering processing costs.

[0005] Specifically, this utility model discloses an injection mold for processing the left and right hinges of a notebook computer, comprising: an upper mold and a lower mold.

[0013] Furthermore, the end of the molding block has a molding arc surface, and multiple molding blocks are arranged around the cavities of the left and right rotating shafts, forming cavities inside that have the same shape as the left and right rotating shafts.

[0014] The advantage of adopting the above technical solution is that the surrounding molding arc surface forms the cavity of the left and right rotating shafts. When demolding, the molding block moves to all sides, which facilitates demolding. Different molding blocks can be replaced to achieve the processing of different rotating shafts, making the entire mold reusable and reducing production costs.

[0015] Furthermore, the lower template is also provided with a core body one and a core body two, the tops of which extend into the left rotating shaft cavity and the right rotating shaft cavity, respectively.

[0016] The advantage of adopting the above technical solution is that core one and core two are used to form the inner surfaces of the left and right rotating shafts, so that the injection-molded products meet the requirements and ensure product quality.

[0017] Furthermore, a lifting block is provided inside the upper template, and the lifting block is provided with an inclined surface that cooperates with the forming block, and the forming block slides along the inclined surface.

[0018] The advantage of adopting the above technical solution is that the lifting block plays a limiting role, the exit rod plays a driving role, and the lifting block makes the movement of the forming block smooth, thus ensuring product quality.

[0019] Furthermore, the upper mold is provided with an inlet, the inlet is connected to a channel, and the channel is provided with branches leading to the left rotating shaft cavity and the right rotating shaft cavity respectively.

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] like Figure 1-8 As shown, this utility model discloses an injection mold for processing the left and right hinges of a notebook computer, comprising: an upper mold and a lower mold. The upper mold includes an upper mold base 1, an upper pad 2, and an upper template 3. The lower mold includes a lower template 4, a lower pad 5, and a lower mold base 6. A molding assembly is provided in the lower template 4, including an upper mold core 31 disposed in the upper template 3, a lower mold core 42 disposed in the lower template 4, and molding blocks 7 disposed around the perimeter. The molding blocks 7 and the upper mold core 31 and lower mold core 42 form a left hinge cavity 71 and a right hinge cavity 72. The molding blocks 7 are connected to an ejection assembly. When the mold is opened, the ejection assembly drives the molding blocks 7 away from the left hinge cavity 71 and the right hinge cavity 72.

[0038] The advantages of adopting the above technical solution are that it completes the processing of the left and right rotating shafts in one go, improves processing efficiency, ensures product quality, and increases yield.

[0039] In some implementations, the ejection assembly includes an ejection rod 8 disposed within the upper mold. The upper end of the ejection rod 8 is fixed within the upper mold plate 3. As the mold opens and rises, the ejection rod 8 is tilted, tilting away from the injection cavity. The lower end of the ejection rod 8 is inserted into the molding block 7. The molding block 7 has an inclined through hole for the ejection rod 8 to pass through. The lower mold plate 4 has a moving groove along which the molding block 7 moves. During the mold opening process, the ejection rod 8 moves upward. Due to its tilted position, the ejection rod 8 pushes the molding block 7 outwards during this movement, achieving mold opening from all sides.

[0040] In some implementations, an ejection assembly is provided within the lower mold. This assembly includes an ejector plate 9 and an ejector rod 91. The ejector plate 9 is located below the lower mold plate 4, and the ejector rod 91 is fixed to the ejector plate 9, moving up and down with it. A guide rod is provided within the lower mold base 6, along which the ejector plate 9 moves to ensure accurate ejection positioning. This ejection assembly enables ejection and demolding. After demolding, a robotic arm picks up the product, and then the mold closes for the next operation, resulting in a high degree of automation and rapid processing.

[0041] The ejector plate 9 rises via an ejector rod on the injection molding machine. A reset seat 92 is mounted on the side of the ejector plate 9, and a movable rod 93 is mounted on the side of the lower mold plate 4. The upper end of the movable rod 93 is rotatably connected to the lower mold plate 4. A reset rod 94 is provided on the side of the reset seat 92. The reset rod 94 is vertically fixed to the upper mold plate 3 by screws. After post-processing, the ejector assembly demolds the product. The reset seat 92 moves with the ejector plate 9, causing the movable rod 93 to rotate. When the mold is closed, the lower end of the reset rod 94 pushes the movable rod 93 to rotate in the opposite direction, causing the movable rod 93 to exert force on the reset seat 92, thus resetting the ejector assembly and improving the automation level of the injection mold.

[0042] Furthermore, a bottom block 43 is provided inside the lower mold core 42. The bottom block 43 is located at the bottom of the left rotating shaft cavity 71 and the right rotating shaft cavity 72. The bottom block 43, the molding blocks 7 located around it, and the upper mold core 31 form an injection molding cavity. The bottom of the bottom block 43 is connected to the ejector rod 91. Driven by the ejector plate 9, the ejector rod 91 extends to complete the ejection operation. The bottom block 43 facilitates product demolding, lifts the product upward, and avoids product damage.

[0043] Furthermore, the end of the molding block 7 has a molding arc surface 73. Multiple molding blocks 7 are arranged around the left and right rotating shaft cavities 72, forming cavities with the same shape as the left and right rotating shafts, and there are eight of them. The number of ejection rods 8 is the same as the number of molding blocks 7, driving the molding blocks 7 to move. The molding arc surface 73 surrounding the mold forms the cavities of the left and right rotating shafts. During demolding, the molding blocks 7 move to all sides for easy demolding. By replacing different molding blocks 7, different rotating shafts can be processed, allowing the entire mold to be reused and reducing production costs.

[0044] In some implementation schemes, the lower mold plate 4 is also provided with a core 44 and a core 45. The tops of the core 44 and the core 45 extend into the left rotating shaft cavity 71 and the right rotating shaft cavity 72, respectively. The core 44 and the core 45 have molding surfaces for molding the internal structure of the product. They are fixedly installed in the lower mold to ensure that the injection-molded product meets the requirements and guarantees product quality.

[0045] Furthermore, a lifting block 32 is provided inside the upper mold plate 3. The lifting block 32 has an inclined surface that cooperates with the forming block 7. The forming block 7 slides along the inclined surface. The lifting block 32 is installed inside the upper mold plate 3. As the upper mold plate 3 moves up and down, the forming block 7 has an inclined end face. This end face contacts and slides with the lifting block 32, causing the lifting block 32 to rise. Due to the inclined surface, the forming block 7 moves horizontally under the drive of the exit rod 8, realizing the mold opening action. At the same time, the upper mold and the lower mold are also provided with cooperating guide pillars and guide sleeves to ensure accurate mold opening and closing positions, smooth movement of the forming block 7, and ensure product quality.

[0046] In some implementation schemes, an inlet 11 is provided inside the upper mold base. The inlet 11 is connected to a channel 12, which has branches leading to the left rotating shaft cavity 71 and the right rotating shaft cavity 72 respectively. A feeding device can be connected to the upper side of the upper mold to supply fluid material. The material enters the left rotating shaft cavity and the right rotating shaft cavity 72 through the channel 12, completing the production of two rotating shafts at one time. This reduces the design and use of one set of molds, effectively improving efficiency and reducing costs.

[0047] Furthermore, cooling channels 13 are provided in the upper and lower molds. The cooling channels 13 are provided with inlets and outlets. The inlets and outlets are installed on the side of the mold and are directly connected to the liquid supply pipe during use. The coolant flows in the pipes, which plays a role in rapid cooling. At the same time, the cooling channels 13 have multiple bends and branches, which surround the left and right rotating shaft cavities to ensure rapid cooling and molding of the injection molded products and improve processing efficiency.

[0048] In some implementations, the inclined surface of the lifting block 32 is provided with a contact plate 311, which is attached to the inclined surface by countersunk screws and contacts the molding block 7. The contact plate 311 contacts the molding block 7, which can prevent wear of the lifting block 32. At the same time, the position of the lifting plate can be adjusted by replacing and adjusting the position of the lifting plate to adjust the injection cavity and ensure product quality.

[0049] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
