Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a quick-change insert device for injection molds used in communication housings. Background Technology

[0002] In the field of communication equipment manufacturing, the communication housing is a key component that protects internal components and ensures stable operation of the equipment. The efficiency and accuracy of the replacement of injection mold inserts have become important factors restricting the production rhythm of communication housings. In order to adapt to the market's demand for rapid iteration of communication equipment and improve the flexibility of the production line.

[0003] However, the current injection mold insert replacement devices have many drawbacks. Traditional devices mostly rely on manual operation, and operators need rich experience and skilled techniques to complete the positioning, installation and fixation of inserts. Not only is the replacement process time-consuming, but it is also very easy for human error to cause the inserts to be installed in the wrong place, which in turn leads to problems such as mold wear and product size deviation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-change insert device for injection molds used in communication housings, which aims to improve the problem that the traditional injection mold insert replacement device has a long replacement process and is prone to improper installation due to human error.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A quick-change insert device for injection molds used in communication housings includes a base. A first electric push rod is fixedly connected to the interior of one side of the base. The output end of the first electric push rod is connected to a first mold, the interior of which has a glue injection port. A second mold is disposed outside the first mold. A second electric push rod is fixedly connected to the interior of the other side of the base, the output end of which is connected to the exterior of the second mold. A slider is slidably connected inside the base. A support rod is fixedly connected to the top of the slider. An inner support block is fitted onto the exterior of the support rod, and a snap-fit ​​groove is formed inside the inner support block. A sliding rod is slidably connected inside the support rod, and a spring is disposed on the lower surface of the sliding rod. One end of the spring is located inside the support rod. The top end of the slide rod is rotatably connected to a first connecting rod. One end of the first connecting rod is rotatably connected to a locking block. The outside of the locking block is rotatably connected to a second connecting rod. One end of the second connecting rod is rotatably connected to the inside of the support rod. The locking block is engaged in the locking groove. A motor is fixedly connected to the outside of the base. The output end of the motor is connected to a first gear. The first gear meshes with a second gear and a third gear. A first screw is fixedly connected to the outside of the second gear. A second screw is fixedly connected to the outside of the third gear. Both the first screw and the second screw are rotatably connected inside the base and are threadedly connected to the slider.

[0006] This utility model has the following beneficial effects: 1. In this utility model, by pushing the slide rod downward to slide the spring, the slide rod drives the locking block to rotate towards the center of the slide rod through the first connecting rod, so that the locking block disengages from the locking groove inside the inner support block; after the slide rod is released, the spring releases its elastic force to push the slide rod upward to slide the locking block into the locking groove, thereby facilitating the installation and disassembly of the inner support block and preventing the inner support block from disengaging from the support rod.

[0007] 2. In this utility model, the motor drives the first screw and the second screw to rotate through the first gear, the second gear and the third gear. The two screws together drive the slider to move inside the base, so that the support rod and the inner support block can be stably adjusted along the base, reducing the possibility of the slider deviating during movement.

[0010] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0011] Reference Figures 1-4This utility model provides an embodiment of a quick-change insert device for injection molds used in communication housings, comprising a base 1, a first electric push rod 2 fixedly connected to one side of the base 1, the output end of the first electric push rod 2 connected to a first mold 3, the first mold 3 having an injection port 4 inside, and a second mold 5 outside the first mold 3; a second electric push rod 6 fixedly connected to the other side of the base 1, the output end of the second electric push rod 6 connected to the outside of the second mold 5; a slider 7 slidably connected inside the base 1, a support rod 8 fixedly connected to the top of the slider 7, an inner support block 10 sleeved on the outside of the support rod 8, and a snap-fit ​​groove inside the inner support block 10; a slide rod 901 slidably connected inside the support rod 8, and a spring 905 provided on the lower surface of the slide rod 901; the spring 905... One end of the slide bar 901 is located inside the support rod 8. The top end of the slide bar 901 is rotatably connected to a first connecting rod 902. One end of the first connecting rod 902 is rotatably connected to a locking block 903. The outside of the locking block 903 is rotatably connected to a second connecting rod 904. One end of the second connecting rod 904 is rotatably connected to the inside of the support rod 8. The locking block 903 is engaged in the locking groove. A motor 11 is fixedly connected to the outside of the base 1. The output end of the motor 11 is connected to a first gear 12. The first gear 12 is meshed with a second gear 13 and a third gear 15. A first screw 14 is fixedly connected to the outside of the second gear 13. A second screw 16 is fixedly connected to the outside of the third gear 15. Both the first screw 14 and the second screw 16 are rotatably connected inside the base 1 and are threadedly connected to the slide bar 7.

[0012] Specifically, the first electric push rod 2 is used to push the first mold 3, and the second electric push rod 6 is used to push the second mold 5, so that the first mold 3 and the second mold 5 are brought closer together to form a mold cavity. The injection port 4 is used to inject molding material into the mold cavity. The base 1 has a groove inside for the slider 7 to slide. The slider 7 is used to drive the support rod 8 and the inner support block 10 to adjust their positions. The inner support block 10 is sleeved on the outside of the support rod 8. The support rod 8 guides the installation direction of the inner support block 10 and restricts the lateral movement of the inner support block 10 relative to the support rod 8. After the locking block 903 enters the locking groove, it restricts the inner support block 10 from disengaging from the support rod 8 in the disassembly direction.

[0013] When the slide bar 901 is pushed downwards, the slide bar 901 causes the spring 905 to contract, and through the first connecting rod 902, it drives the locking block 903 to rotate towards the center of the slide bar 901, causing the locking block 903 to disengage from the locking groove inside the inner support block 10, so that the inner support block 10 can be removed from the support rod 8. When installing the inner support block 10, the inner support block 10 is placed outside the support rod 8. After the slide bar 901 is released, the spring 905 releases its elastic force to push the slide bar 901 to slide upwards. The slide bar 901 drives the locking block 903 to rotate through the first connecting rod 902 and enter the locking groove. The locking block 903 cooperates with the locking groove to prevent the inner support block 10 from disengaging from the support rod 8, and the spring 905 is used to push the slide bar 901 to reset and maintain the locking state of the locking block 903.

[0014] Motor 11 drives the first gear 12 to rotate, and the first gear 12 simultaneously drives the second gear 13 and the third gear 15 to rotate. The second gear 13 and the third gear 15 respectively drive the first screw 14 and the second screw 16 to rotate. The first screw 14 and the second screw 16 together form two threaded transmission positions with the slider 7. The two screws together drive the slider 7 to slide inside the base 1, thereby adjusting the position of the support rod 8 and the inner support block 10 and reducing the possibility of the slider 7 deviating during movement.

[0015] Working principle: When the inner support block 10 needs to be replaced, push the slide rod 901 downward to cause the spring 905 to contract. The slide rod 901 drives the first connecting rod 902 to rotate. The first connecting rod 902 drives the locking block 903 to rotate. The locking block 903 drives the second connecting rod 904 to rotate inside the support rod 8, causing the locking block 903 to rotate towards the center of the slide rod 901, thereby releasing the locking relationship between the locking block 903 and the locking groove inside the inner support block 10, and removing the inner support block 10 from the support rod 8. When installing the inner support block 10, place the inner support block 10 outside the support rod 8. After releasing the slide rod 901, the spring 905 releases its elastic force to push the slide rod 901 upward. The slide rod 901 drives the locking block 903 to rotate into the locking groove inside the inner support block 10, thereby completing the installation of the inner support block 10.

[0016] When the position of the inner support block 10 needs to be adjusted, the motor 11 is started. The motor 11 drives the first gear 12 to rotate. The first gear 12 drives the second gear 13 and the third gear 15 to rotate. The second gear 13 and the third gear 15 drive the first screw 14 and the second screw 16 to rotate. The first screw 14 and the second screw 16 together drive the slider 7 to slide inside the base 1. The slider 7 drives the support rod 8 and the inner support block 10 to move to a position that matches the first mold 3 and the second mold 5. The first electric push rod 2 and the second electric push rod 6 drive the first mold 3 and the second mold 5 to move closer to each other, so that the inner support block 10 is located in the formed mold cavity for injection molding of the communication shell.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
