[0002] As the application of consumer electronics becomes more and more widespread, electronic products such as mobile phones and tablet computers are increasingly entering people's lives. In existing electronic products, plastic is injected on the outside of the metal panel. By combining metal and plastic, it is not only novel in style but also strong in structure, which has a great trend of replacing single plastic products.

[0003] Most of the existing metal panel injection plastics achieve the adsorption of metal steel sheets through a suction cup structure in the injection mold. In the prior art, the adsorption function is achieved by setting a suction cup on the mold core. However, after the injection mold has been working for a certain period of time, the suction cup will age or be damaged. At this time, it is often necessary to remove the entire mold core or even the entire mold to replace the suction cup. Moreover, most of the suction cups in the prior art are embedded in the mold core, so it is not easy to remove the suction cup even if the mold core or the entire mold is removed. Therefore, it takes a lot of time to repair the mold. At the same time, the cost of mold repair is also quite expensive. In addition, the long mold repair time causes a lot of trouble to the company due to the shutdown. Utility Model Content

It is only for the convenience of description and simplified description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0029] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0030] See also Figure 1-Figure 10 The utility model discloses a suction cup quick release assembly 60, which is installed on a mold core 40 and is used to absorb and fix an injection molded product 100 in an injection mold. In this embodiment, the injection molded product 100 is composed of a plastic shell 102 injected on the periphery of a metal panel 101. The metal panel 101 is absorbed by the suction cup quick release assembly 60, and then the plastic shell 102 is injection molded at a circumferential position of the metal panel 101. In more detail, the mold core 40 is provided with a mounting hole that runs through the upper and lower surfaces of the mold core 40, and the suction cup quick release assembly 60 is installed in the mounting hole.

[0031] See also Figure 3 , Figure 4 and Figure 6 The suction cup quick release assembly 60 further includes a suction cup rod 61, a suction cup insert 62 and a suction cup 63. The lower end of the suction cup insert 62 is connected to the upper end of the suction cup rod 61 by a thread, and the lower end of the suction cup 63 is sleeved on the upper end of the suction cup insert 62. In this embodiment, the suction cup 63 is made of rubber, silicone, TPE or soft PVC. The suction cup 63 protrudes upward from the upper surface of the mold core 40 to adsorb the metal panel 101, and the suction cup rod 61 protrudes downward from the lower surface of the mold core 40. The suction cup rod 61, the suction cup insert 62 and the suction cup 63 are all penetrated by an air path 64 that is interconnected. The air path 64 is used to connect with an external pneumatic device. Its first function is to generate suction in the pneumatic device and transmit it to the metal panel 101 through the air path 64 to realize the adsorption and fixing function; its second function is to detect whether the metal panel 101 is placed on the mold core 40. When it is detected that the metal panel 101 is already on the mold core 40, it further indicates that the injection mold is allowed to enter the mold closing state.

[0032] See also Figure 7Further, the suction cup rod 61 includes a first suction cup rod 611 and a second suction cup rod 612, and the first suction cup rod 611 and the second suction cup rod 612 are connected by threads. The lower end of the suction cup insert 62 is connected to the upper end of the first suction cup rod 611 by threads. In this embodiment, by setting multiple sections of the suction cup rod 61, its function is to prevent a single too long suction cup rod 61 from being easily deformed and bent by impact when the injection mold is closed, and finally affecting the adsorption capacity of the suction cup 63.

[0033] See also Figure 6 , Figure 7 and Fig.10 The outer circumference of the suction cup insert 62 is provided with an outer hexagonal structure 621, and the circumference of the air passage 64 of the suction cup insert 62 is provided with an inner hexagonal interface 622. The outer hexagonal structure 621 facilitates the quick fastening of the suction cup insert 62 to the suction cup rod 61 when the suction cup quick release assembly 60 is installed. The inner hexagonal interface 622 facilitates the use of a hexagonal wrench 200 to remove the combination of the suction cup insert 62 and the suction cup 63 when the suction cup 63 needs to be replaced, and replace the new suction cup 63, and then use the hexagonal wrench 200 to install the suction cup insert 62 equipped with the new suction cup 63 back to the suction cup rod 61. By replacing partial parts of the suction cup quick release assembly 60, quick replacement can be achieved without disassembling the injection mold, which greatly saves mold repair time and mold repair costs.

[0034] Furthermore, the suction cup 63 includes a seat body 631 and a plate body 632, wherein the seat body 631 is sleeved on the upper end of the suction cup insert 62 and fixed on the suction cup insert 62, and the plate body 632 is extended outward from the upper end of the seat body 631 in a trumpet shape. The trumpet-shaped plate body 632 is more conducive to adsorbing the metal panel 101. When the plate body 632 of the suction cup 63 is worn out after several uses and cannot achieve sufficient adsorption force, the mold can be quickly repaired by removing the suction cup insert 62, removing the damaged suction cup 63 and then replacing it with a new one, without removing the injection mold, which greatly saves the mold repair time and mold repair cost.

[0035] See also Figure 1-Figure 5The utility model also discloses an injection mold, including the above-mentioned suction cup quick release assembly 60, the injection mold also includes a lower mold base 30 and a lower mold plate 10 located below the lower mold base 30, the mold core 40 for installing the suction cup quick release assembly 60 is installed on the lower mold base 30, the lower mold base 30 is penetrated by a through hole, the suction cup rod 61 is arranged in the through hole, and the lower end of the suction cup rod 61 is fixedly connected to the lower mold base 30. Furthermore, the lower mold base 30 is provided with an exhaust channel 11, the air path channel 64 is connected to the exhaust channel 11, and the exhaust channel 11 is connected to an external pneumatic device.

[0036] See also Figure 3 , Figure 5 and Figure 6 Further, the suction cup rod 61 includes a first suction cup rod 611 and a second suction cup rod 612, and the first suction cup rod 611 and the second suction cup rod 612 are connected by threads. The lower end of the suction cup insert 62 is connected to the upper end of the first suction cup rod 611 by threads, and the lower end of the second suction cup rod 612 is fixedly connected to the lower mold base 30.

[0037] Furthermore, the injection mold further includes an ejector mechanism 70 and an ejector plate 50, and the ejector plate 50 is movably disposed between the lower mold plate 10 and the lower mold base 30. The lower end of the ejector mechanism 70 is fixedly connected to the ejector plate 50, and the mold core 40 is provided with an active hole extending upward and downward corresponding to the ejector mechanism 70, and the ejector mechanism 70 is movably disposed in the active hole.

[0038] When the injection mold changes from an open mold state to a closed mold state, the ejector plate 50 moves downward and finally abuts against the lower mold plate 10; when the injection mold changes from a closed mold state to an open mold state, the ejector plate 50 moves upward and pushes the ejection mechanism 70 to eject the product.

[0039] More specifically, a return spring is installed between the ejector plate 50 and the lower mold base 30. When the injection mold is changed from the mold opening state to the mold closing state, the ejector plate 50 is pushed away from the lower mold base 30 by the restoring elastic force of the return spring, and the ejector plate 50 finally abuts against the lower mold plate 10.

[0040] Furthermore, the ejector plate 50 is provided with avoidance holes extending from top to bottom, and the suction cup rod 61 passes through the avoidance holes, and the suction cup rod 61 and the ejector plate 50 do not interfere with each other.

[0041] In more detail, the ejection mechanism 70 includes an inclined ejection mechanism and a straight ejection mechanism, wherein the inclined ejection mechanism includes an inclined ejector rod whose lower end is fixedly connected to the ejector plate 50 and an inclined ejector member movably connected to the upper end of the inclined ejector rod, wherein the inclined ejector member is movably arranged in the movable hole, and the straight ejection mechanism includes a straight ejector rod whose lower end is fixedly connected to the ejector plate 50, wherein the upper end of the straight ejector rod is movably arranged in the movable hole. When the injection mold is changed from a mold closing state to a mold opening state, the ejector plate 50 moves upward and pushes the straight ejector rod and the inclined ejector rod to move upward, and the upper end of the straight ejector rod pushes the injection molded product 100 upward, and at the same time, the inclined ejector rod drives the inclined ejector member to move upward and inward to separate from the side wall of the injection molded product 100 and eject the injection molded product 100 upward.

[0042] See also Figure 1 and Figure 3 The injection mold further includes a pair of fixing plates 20 fixed between the lower mold base 30 and the lower mold plate 10, the pair of fixing plates 20 are arranged at intervals, and the ejector plate 50 is located between the pair of fixing plates 20. By arranging the fixing plates 20 to be supported between the lower mold plate 10 and the lower mold base 30, the injection mold can be effectively prevented from being damaged due to the pressure of the downward impact during the mold closing process.

[0043] Furthermore, the injection mold further includes a slide mechanism 80, the mold core 40 is provided with a slide groove, the slide mechanism 80 is movably arranged in the slide groove, and the slide mechanism 80 and the mold core together form an injection space. More specifically, in this embodiment, the injection mold includes a plurality of the slide mechanisms 80, and the plurality of the slide mechanisms 80 are arranged around the injection molded product 100. When the injection mold is in a closed mold state, the plurality of the slide mechanisms 80 all move toward the center of the mold core 40, and finally the plurality of the slide mechanisms 80 are arranged in a closed loop to realize the injection molding of the metal panel 101 in the injection molding space to obtain the injection molded product 100.

[0044] See also Figure 1 and Figure 5 The mold core 40 is provided with a plurality of positioning posts 90, which are used to position the metal panel 101. The positioning posts 90 have a foolproof effect and can effectively prevent the metal panel 101 from being placed in the opposite direction or rotated at a certain angle. When the metal panel 101 is placed in the opposite direction or rotated at a certain angle, the metal panel 101 cannot be fitted with the suction cup 63, and the gas in the gas passage 64 cannot detect that the metal panel 101 has been placed, so the injection mold cannot be closed.

[0045] The suction cup quick-release assembly and the injection mold provided by the utility model are not only simple in structure but also convenient for repair and replacement, thus greatly saving mold repair time and mold repair cost.

[0046] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto.
