Description

Technical Field

[0001] This invention relates to the field of notebook hinge processing technology, and in particular to a mold for preparing the left and right hinges of a notebook computer. Background Technology

[0002] The left and right hinges of a laptop are a key component in laptop design, connecting the screen to the main unit and withstanding both bending and torque during rotation. Currently, the internal plates of the hinges are mostly pre-formed using aluminum extrusion or welding, and then CNC machined into the finished product. Since the hinge itself is a stress-concentrated component when the laptop is opened and closed, welding or aluminum extrusion methods easily create stress concentration at the connection point, making the hinge prone to damage during use.

[0003] For example, application number CN202010196027.8 discloses a laptop hinge processing device and method. During processing, the hinge body is squeezed by left and right clamping blocks, causing the inner baffle to be cold-forged. Laptop hinges processed using this method also require burr removal from the outer end face of the hinge body. With the research and development of new materials, the strength of plastics has improved, and metal hinges are gradually being phased out of the market. Furthermore, the efficiency of molding one hinge at a time is low and cannot meet current production needs. Therefore, it is necessary to develop a molding die with high production efficiency.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] like Figure 1-12 As shown, this utility model discloses a mold for manufacturing the left and right side hinges of a notebook computer, including a fixed mold 1 and a moving mold 2 that cooperate with each other;

[0034] The fixed mold 1 includes a fixed mold base 11 and a fixed template 12. The lower surface of the fixed template 12 has a plurality of fixed mold inserts 16 and a sleeve plate 15 for connecting the fixed mold inserts 16. The lower surface of each fixed mold insert 16 has an upper forming body 17.

[0035] The moving mold 2 includes a moving mold base 21 and a moving mold plate 22 connected to the moving mold base 21. The moving mold plate 22 has a moving mold insert 23, and the upper surface of the moving mold insert 23 has a lower mold body 24 that cooperates with the upper molded body 17.

[0036] The upper surface of the moving template 22 is also provided with a sliding side molding insert 26. The side molding insert 26 has a side molding surface 27 that cooperates with the upper molding body 17 and the lower molding body 24. The side molding surface 27 is located on the side wall of the side molding insert 26. The side molding surface 27, the upper molding body 17 and the lower molding body 24 constitute the product cavity 3 of the left and right pivots of the notebook.

[0037] The injection material enters the product cavity 3 through the inlet 111 of the fixed mold base 11 and the injection runner 13 of the fixed mold plate 12.

[0038] This invention achieves injection molding of multiple notebook left and right hinges 4 by cooperating with the lower molding body 24, the side molding body and the upper molding body 17, thereby improving production efficiency and reducing production costs.

[0039] In some embodiments of this utility model, the moving mold insert 23 is disposed below the side forming insert 26, and the moving mold insert 23 is slidably connected to the moving template 22 along the movement direction of the moving mold 2.

[0040] The side molding inserts 26 are located on both sides of the moving mold plate 22. The side molding inserts 26 are controlled by guide posts 14 connected to the fixed mold plate 12, and the guide posts 14 are slidably connected to the side molding inserts 26 and are inclined to the horizontal plane. When the moving mold 2 moves downward, under the action of the guide posts 14, the side molding inserts 26 on both sides move outward along the moving mold plate 22, so that the side molding surface 27 separates from the product, which facilitates product demolding.

[0041] In some embodiments of this utility model, the injection molding runner 13 includes a first runner 131 and a second runner 132. The first runner 131 is placed on the upper surface of the fixed mold plate 12, and its transverse cross-section is S-shaped. The second runner 132 is perpendicular to the first runner 131, with one end connected to the first runner 131 and the other end connected to the product cavity 3. In this solution, four product cavities 3 are provided. The S-shaped first runner 131 facilitates the uniform entry of injection molding material into each product cavity 3, thereby improving the molding quality of the product.

[0042] In this invention, the left and right hinges 4 of the notebook computer have hollow first cavities 41 and second cavities 42 at their ends, respectively, and an intermediate baffle 43 is provided between the first cavities 41 and the second cavities 42. The contour of the upper molded body 17 matches the contour of the first cavity 41, and the contour of the lower molded body 24 matches the contour of the second cavity 42. Using a contour-following structure can improve the surface molding accuracy of the product and reduce subsequent processing.

[0043] To facilitate product demolding, the moving mold 2 also includes a lifting plate 28, which is movably disposed between the moving mold base 21 and the moving mold plate 22. The lifting plate 28 is fixedly connected to the moving mold insert 23 via a lifting rod 29. After the moving mold 2 moves downward, the lifting plate 28 drives the lifting rod 29 and the moving mold insert 23 to move upward, pushing out the molded product for easy removal.

[0044] In some embodiments of this utility model, in order to improve the motion accuracy of the moving mold insert 23, a guide block 25 is also provided on one side of the moving mold insert 23. The guide block 25 is slidably connected to the wedge groove 221 of the moving mold plate 22, and the guide block 25 has a wedge surface 222 that matches the wedge groove 221. The height of the guide block 25 is greater than the height of the lifting plate 28. Therefore, the guide block 25 will always move up and down in the wedge groove 221, thereby improving the motion accuracy of the moving mold insert 23.

[0045] The working principle of this utility model is as follows:

[0046] The plunger material enters the product cavity 3 through the feed port 111 and injection runner 13 to cool the product. Then the moving mold 2 moves downward. While the moving mold 2 is moving, under the action of the guide post 14 on the fixed mold plate 12, the side molding inserts 26 on both sides of the moving mold plate 22 move outward along the moving mold plate 22, so that the side molding surface 27 of the side molding insert 26 separates from the product. Then the lifting plate 28 moves upward, and at the same time drives the lifting rod 29 and the moving mold insert 23 to move upward, pushing out the molded product, which is then taken out by the material taking component.

[0047] 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 all fall within the protection scope of this utility model.
