Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a side locking structure for an injection mold and the injection mold. Background Art

[0002] The side lock is an indispensable part of the injection mold. Its main purpose is to be used for precise positioning when the front mold and the back mold are closed. At the same time, a side lock is arranged on the four outer sides of the injection mold in sequence to prevent the injection mold from being misaligned during the closing process and causing the risk of mold collision.

[0003] Especially when injection molding products such as plastic shells, bases, back covers, panels, buttons or switch brackets around electronic devices, multiple molding inserts are usually designed in the corresponding injection molds. In order to ensure that the molding ends of the molding inserts in this part will not cause damage to the mold cavity during mold closing, high requirements are placed on the precise positioning of the side locks during mold closing. Generally, the side lock design is usually a concave-convex structure, and only the convex and concave ends of the side lock are precisely processed to ensure that the convex and concave ends of the side lock have a high matching tolerance.

[0039] See also Figures 1 to 7 In order to better understand the side locking structure 10 for the injection mold of the present application, the side locking structure 10 for the injection mold is further explained below:

[0040] The side lock structure 10 for the injection mold of one embodiment includes a positioning lock block 100 and an alignment lock block 200. The positioning lock block 100 is provided with a positioning docking port 101, and the positioning lock block 100 is fixedly installed on the fixed mold mechanism 700. The alignment lock block 200 is formed with a docking protrusion 210, and the alignment lock block 200 is fixedly installed on the movable mold mechanism 800.

[0041] When the movable mold mechanism 800 and the fixed mold mechanism 700 are molded together, the docking protrusion 210 enters the positioning docking port 101, so that the first guide bevel 2120 and the second guide bevel 2140, as well as the first wear-resistant surface 2110 and the second wear-resistant surface 2130 respectively slide and rub synchronously on the inner wall of the positioning docking port 101.

[0042] In this embodiment, a first guide fillet 2150 and a second guide fillet 2160 are provided to enhance the guideability of the end of the docking protrusion 210 , thereby effectively reducing the risk of misalignment and collision of the docking protrusion 210 at the moment of entering the positioning docking interface 101 .

[0043] Furthermore, the first guiding slope 2120 and the second guiding slope 2140 can effectively reduce the intensity of the sliding friction between the docking protrusion 210 and the inner wall of the positioning docking port 101 , and indirectly provide a good guiding effect for the docking protrusion 210 to enter the positioning docking port 101 .

[0044] Furthermore, by filling the lubricant in the multiple first guide oil grooves 2111 and the multiple second guide oil grooves 2131, the sliding friction between the first wear-resistant surface 2110 and the second wear-resistant surface 2130 and the inner wall of the positioning docking interface 101 is effectively reduced, so that the positioning accuracy of the docking protrusion 210 and the positioning docking interface 101 is effectively ensured, and the wear resistance of the docking protrusion 210 on the positioning locking block 200 is improved at the same time, thereby ensuring that the molding end of the molding insert will not cause bump damage to the mold cavity when the injection mold is closed.

[0045] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, in one embodiment, the positioning lock block 100 is provided with a first countersunk hole 102 and a first through hole 103 which are connected in sequence, and the positioning lock block 100 is also provided with a second countersunk hole 104 and a second through hole 105 which are connected in sequence;

[0046] The edge locking structure 10 for the injection mold also includes a first fastening screw 300 and a second fastening screw 400; the threaded end of the first fastening screw 300 is sequentially penetrated through the first countersunk hole 102 and the first through hole 103, and is threadedly connected to the fixed mold mechanism 700; the threaded end of the second fastening screw 400 is sequentially penetrated through the second countersunk hole 104 and the second through hole 105, and is threadedly connected to the fixed mold mechanism 700.

[0047] In one embodiment, the alignment lock block 200 is provided with a third countersunk hole 201 and a third through hole 202 which are connected in sequence, and the positioning lock block 100 is further provided with a fourth countersunk hole 203 and a fourth through hole 204 which are connected in sequence;

[0048] The edge locking structure 10 for the injection mold also includes a third fastening screw 500 and a fourth fastening screw 600; the threaded end of the third fastening screw 500 is sequentially penetrated through the third countersunk hole 201 and the third through hole 202, and is threadedly connected to the movable mold mechanism 800; the threaded end of the fourth fastening screw 600 is sequentially penetrated through the fourth countersunk hole 203 and the fourth through hole 204, and is threadedly connected to the movable mold mechanism 800.

[0049] It can be understood that the first fastening screw 300 and the second fastening screw 400 can realize a reliable threaded connection between the positioning locking block 100 and the fixed mold mechanism 700; similarly, the third fastening screw 500 and the fourth fastening screw 600 can realize a reliable threaded connection between the alignment locking block 200 and the movable mold mechanism 800. In this embodiment, the convenience and efficiency of the installation and disassembly of the positioning locking block 100 and the alignment locking block 200 can be improved by the threaded connection. In other embodiments, in order to further enhance the stability of the installation of the positioning locking block 100 and the alignment locking block 200, the user can increase the number of countersunk holes, through holes and fastening screws according to actual needs.

[0050] like Figures 3 to 7 As shown, in one embodiment, the angle formed by the first guide bevel 2120 and the first wear-resistant surface 2110 is less than 1.5 degrees; the angle formed by the second guide bevel 2140 and the second wear-resistant surface 2130 is less than 1.5 degrees.

[0051] It can be understood that in this embodiment, by limiting the angle of the first guide bevel 2120 and the second guide bevel 2140, the first guide bevel 2120 and the second guide bevel 2140 can effectively reduce the intensity of the sliding friction between the docking protrusion 210 and the inner wall of the positioning docking interface 101, thereby indirectly providing a good guiding effect for the docking protrusion 210 to enter the positioning docking interface 101.

[0052] It should be noted that if Figure 6 As shown, X is the angle formed by the first guiding inclined surface 2120 and the first wear-resistant surface 2110, and Y is the angle formed by the second guiding inclined surface 2140 and the second wear-resistant surface 2130. The arrangement of the first guiding inclined surface 2120 and the second guiding inclined surface 2140 makes the head of the docking protrusion 210 to be retracted, providing a good guiding effect for the docking protrusion 210 to enter the positioning docking port 101.

[0053] like Figures 2 to 5 As shown, in one embodiment, each of the first lubricating oil guide grooves 2111 includes a plurality of first spherical grooves 2111a and a plurality of first strip grooves 2111b, and a corresponding first strip groove 2111b is provided between two adjacent first spherical grooves 2111a, so that the two adjacent first spherical grooves 2111a are connected.

[0054] In one embodiment, the plurality of first oil guide grooves 2111 and the plurality of second oil guide grooves 2131 are distributed linearly.

[0055] It can be understood that the user can first fill the first spherical groove 2111a and the second spherical groove 2131a with lubricant, so that when the movable mold mechanism 800 and the fixed mold mechanism 700 open and close the mold, the first wear-resistant surface 2110 and the second wear-resistant surface 2130 can be covered with lubricant when they slide and rub against the inner wall of the positioning docking port 101, thereby effectively reducing the sliding friction between the first wear-resistant surface 2110 and the second wear-resistant surface 2130 and the inner wall of the positioning docking port 101, so that the positioning accuracy of the docking protrusion 210 and the positioning docking port 101 is effectively ensured, and the wear resistance of the docking protrusion 210 on the alignment locking block 200 is improved at the same time, thereby ensuring that the molding end of the molding insert of the injection mold will not cause bump damage to the mold cavity when the mold is closed.

[0056] like Figures 1 to 5 As shown, in one embodiment, the positioning lock block 100 and the alignment lock block 200 are both integrally formed structures. In one embodiment, the alignment lock block 200 is provided with a first stress relief notch 205 and a second stress relief notch 206, and the first stress relief notch 205 and the second stress relief notch 206 are symmetrically distributed on both sides of the root of the docking protrusion 210.

[0057] It can be understood that the positioning locking block 100 and the alignment locking block 200 are both integrally formed, which can effectively improve the overall structural strength of the positioning locking block 100 and the alignment locking block 200, thereby ensuring that the positioning locking block 100 and the alignment locking block 200 have sufficient structural strength to correct the accuracy of the mold closing during the opening and closing of the movable mold mechanism 800 and the fixed mold mechanism 700, and avoid deformation and dislocation of the docking protrusion 210 of the alignment locking block 200. At the same time, the alignment locking block 200 also effectively avoids the problem of stress concentration on both sides of the root of the docking protrusion 210 through the first stress relief notch 205 and the second stress relief notch 206, so that the docking protrusion 210 is not easy to break, thereby improving the durability of the alignment locking block 200.

[0058] The present application also provides an injection mold, including the side locking structure 10 for the injection mold described in any of the above embodiments, the injection mold having a positioning locking block 100 and an alignment locking block 200, the injection mold also including a fixed mold mechanism 700 and a movable mold mechanism 800, the fixed mold fixing plate of the fixed mold mechanism 700 is provided with a first mounting groove 701, the first mounting groove 701 is used to fix the positioning locking block 100; the movable mold fixing plate of the movable mold mechanism 800 is provided with a second mounting groove 801, the second mounting groove 801 is used to fix the alignment locking block 200.

[0059] In this embodiment, the number of the first installation groove 701 and the number of the second installation groove 801 are four, respectively, and they are located on the four outer sides of the injection mold; correspondingly, the number of the positioning lock block 100 and the alignment lock block 200 are also four, respectively, and they are located on the four outer sides of the injection mold. The above-mentioned injection mold achieves a high matching and docking positioning accuracy between the docking protrusion 210 and the positioning docking interface 101 through the precise positioning of the four sets of side locks, effectively ensuring that the molding end of the molding insert will not cause damage to the mold cavity when the injection mold is closed.

[0060] Compared with the prior art, the utility model has at least the following advantages:

[0061] 1. The first guide fillet and the second guide fillet are provided to enhance the guideability of the end of the docking protrusion, thereby effectively reducing the risk of misalignment and collision of the docking protrusion at the moment of entering the positioning docking interface.

[0062] 2. The first guiding bevel and the second guiding bevel can effectively reduce the intensity of the sliding friction between the docking protrusion and the inner wall of the positioning docking interface, and indirectly provide a good guiding effect for the docking protrusion to enter the positioning docking interface.

The lubricant filled in multiple first lubricating oil grooves and multiple second lubricating oil grooves can effectively reduce the sliding friction between the first wear-resistant surface and the second wear-resistant surface and the inner wall of the positioning docking interface, so that the positioning accuracy of the docking protrusion and the positioning docking interface can be effectively ensured, and the wear resistance of the docking protrusion on the positioning locking block can be improved at the same time, thereby ensuring that the molding end of the molding insert will not cause bump damage to the mold cavity when the injection mold is closed.

[0064] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
