[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 As shown, an injection mold with a quick mold change structure includes a base plate 1. A groove 2 is formed on the upper surface of the base plate 1. A bidirectional spiral rod 23 is rotatably installed inside the groove 2. A motor 13 is installed on the outer surface of the base plate 1. The output end of the motor 13 passes through the base plate 1 and is connected to the bidirectional spiral rod 23. A slider 18 is threadedly connected to the outer surface of the bidirectional spiral rod 23. A first frame 24 is installed on the outer surface of the slider 18. A second double-rod cylinder 19 is installed inside the first frame 24. A second limit block 17 is installed on each of the two output ends of the second double-rod cylinder 19. A lower mold 6 is slidably installed on the outer surfaces of the two second limit blocks 17. A mold groove 22 is formed on the upper surface of the lower mold 6. A groove is formed on the bottom surface of the lower mold 6. The second limit block 17 is connected to the groove.
[0021] A second hydraulic cylinder 20 is installed on the bottom surface of the base plate 1. The output end of the second hydraulic cylinder 20 passes through the base plate 1 and is connected to the outer surface of the lower mold 6. A control box 4 is installed on the upper surface of the base plate 1.
[0022] A support frame 5 is installed on the upper surface of the base plate 1. A first hydraulic cylinder 12 is installed on the upper surface of the support frame 5. The output end of the first hydraulic cylinder 12 passes through the support frame 5 and is then installed with a second frame 25. A first double-rod cylinder 15 is installed inside the second frame 25. A groove is opened on the bottom surface of the upper mold 11 and a first limiting block 14 is connected to the groove.
[0023] Both ends of the first double-rod cylinder 15 are equipped with first limiting blocks 14. The outer surfaces of the two first limiting blocks 14 are slidably mounted with an upper mold 11. The outer surface of the upper mold 11 is equipped with mold protrusions 16.
[0024] A bracket 7 is installed on the upper surface of the base plate 1, and a first electric slide rail 8 is installed on the upper surface of the bracket 7. When changing the upper mold 11, the clamp 10 is moved by the second electric slide rail 21 to fix the removed upper mold 11 and prevent it from falling from a height.
[0025] A support plate 9 is mounted on the upper surface of the first electric slide rail 8, and a second electric slide rail 21 is mounted on the upper surface of the support plate 9.
[0026] Two clamps 10 are installed on the upper surface of the second electric slide rail 21, and multiple support legs 3 are installed on the bottom surface of the base plate 1. Each support leg 3 is equipped with a rubber anti-slip pad, which can reduce the vibration of the equipment and prevent slipping.
[0027] Working principle: First, through unified coordination and control via control box 4, when the lower mold 6 needs to be replaced, motor 13 starts and drives bidirectional spiral rod 23 to drive slider 18 to move in opposite directions along slide groove 2, thereby moving the first frame 24 and the second double-rod cylinder 19 mounted on it to the appropriate position. The second limit blocks 17 at both ends clamp or release the lower mold 6. In conjunction with the second hydraulic cylinder 20, the height of the lower mold 6 is adjusted to complete the rapid replacement and positioning of the lower mold 6. For the replacement of the upper mold 11, the first hydraulic cylinder 12 drives the second frame 25 to move up and down. The first double-rod cylinder 15 clamps or releases the upper mold 11 through the first limit block 14. Through the cooperation of the first electric slide rail 8 on the upper surface of bracket 7 and the second electric slide rail 21 on support plate 9, the clamp 10 can move accurately below the upper mold 11 to accurately catch the upper mold 11 and complete the replacement. Subsequently, the first hydraulic cylinder 12 drives the upper mold 11 to descend, and the mold protrusion 16 cooperates with the mold groove 22 to complete the injection molding.
