The vertical relationships of relative elements and the definitions of front / back in the graphics described herein should be understood by those skilled in the art to refer to the relative positions of the components; therefore, they can all be flipped to present the same component, and all of this should fall within the scope disclosed in this specification.

[0021] refer to Figures 1 to 7An automatic mold moving device is proposed in the embodiments of this application, which includes a frame 1, a mold frame 2, a mold moving support frame 3, a linear drive mechanism 4, a reversing mechanism 5, a rotating arm 6, a positioning concave shaft 7, and a positioning telescopic shaft 8. The mold moving support frame 3 is installed on one side of the frame 1 and can be raised and lowered. The mold frame 2 is slidably mounted inside the frame 1 and on the mold transfer support frame 3. Specifically, the mold transfer support frame 3 is provided with a first guide rail 31, a fixed seat 32, and a mold frame blocking block 33. The frame 1 is provided with a second guide rail 11, and the first guide rail 31 is connected to the second guide rail 11. The mold frame 2 is slidably mounted on the first guide rail 31 and the second guide rail 11 via guide wheels. One end of the rotating arm 6 is connected to the mold frame 2, and the other end is mounted on the fixed seat 32. The linear drive mechanism 4 is mounted on the fixed seat 32 and is connected to the other end of the rotating arm 6 via a reversing mechanism 5. The other end of the rotating arm 6 is provided with a rotating shaft 61. The reversing mechanism 5 is used to convert the linear motion of the linear drive mechanism 4 into the rotation of the rotating arm 6 around its rotating shaft 61, so as to drive the mold frame 2 to move between a first position inside the frame 1 and a second position on the mold transfer support frame 3. Figure 1 This paper shows a schematic diagram of the automatic mold-moving device proposed in this application in the second position state where the mold frame 2 is moved to the mold-moving support frame 3; Figure 2 and Figure 3 The diagram shows partial top views of the automatic mold-moving device proposed in this application, showing the mold frame 2 in its second position on the mold-moving support frame 3 and in its first position within the frame 1. A mold frame blocking block 33 is installed beside the first guide rail 31. In the second position, the mold frame blocking block 33 is located on the side of the mold frame 2 away from the frame. This application achieves automatic movement of the mold frame 2 between the first position within the frame 1 and the second position on the mold-moving support frame 3 by coordinating a linear drive mechanism 4 and a reversing mechanism 5 to drive the rotating arm 6. This reduces the workload of operators and facilitates the placement and removal of the mold within the frame 1. (Reference) Figure 4 The positioning concave shaft 7 is installed on the mold frame 2, and the positioning telescopic shaft 8 is installed on the machine frame 1. When the mold frame 2 drives the mold to slide to the first position, the positioning telescopic shaft 8 is locked in the positioning concave shaft 7. The positioning concave shaft 7 and the positioning telescopic shaft 8 set on the mold frame 2 are used to position the mold frame 2 after it enters the machine frame 1, so as to avoid the mold being not correctly placed in the first position in the machine frame 1, which would lead to unstable quality of the finished product.

[0022] In a specific embodiment, refer to Figure 5The reversing mechanism 5 includes a gear 51, a rack 52, and a rack clamping member 53. The rack 52 is fixedly connected to the linear drive mechanism 4, and the gear 51 is sleeved on the outside of the rotating shaft 61. The gear 51 meshes with the rack 52, and the rack clamping member 53 provides pressure to the rack 52 towards the gear 51. The linear drive mechanism 4 includes a hydraulic cylinder 41 and a piston rod 42. The hydraulic cylinder 41 is fixedly mounted on the mold moving support frame 3, and one end of the piston rod 42 is fixedly connected to the rack 52.

[0023] In a specific embodiment, refer to Figure 1 and Figure 2 It also includes a slider 34, a positioning block 35, and a guide rod 36. The guide rod 36 is installed inside the mold moving support frame 3, and the slider 34 is slidably mounted on the guide rod 36. The slider 34 is connected to a fixed seat 32, and the fixed seat 32 is connected to the other end of the rotating arm 6. Specifically, a linear drive mechanism 4 is installed on the slider 34. The linear drive mechanism 4 drives the rotating arm 6 to rotate through a reversing mechanism 5, causing the mold frame 2 to move back and forth inside and outside the frame 1. During the process of using the rotating arm 6 to drive the mold frame 2 to move back and forth inside and outside the frame 1, the rotating arm 6 drives the slider 34 and the linear drive mechanism 4 to reciprocate along the extension direction of the guide rod 36. Through the structural design of the guide rod 36, the stable operation of the automatic mold moving device is ensured. Furthermore, the positioning block 35 is installed on the guide rod 36. When the slider 34 is in contact with the positioning block 35, the rotating arm 6 drives the mold frame 2 to move into the frame 1 and position the mold frame 2 in a first position or a second position.

[0024] In a specific embodiment, refer to Figure 4 The inner edge of the positioning concave shaft 7 is arc-shaped, and one end of the positioning telescopic shaft 8 is also arc-shaped. Specifically, when the positioning concave shaft 7 moves from the second position to the first position along with the mold frame 2 and moves until the upper edge of the positioning concave shaft 7 abuts against the positioning telescopic shaft 8, the positioning concave shaft 7 continues to move towards the workstation, while the positioning telescopic shaft 8 retracts upward until the arc-shaped portion of the positioning telescopic shaft 8 is located within the positioning concave shaft 7. At this point, the mold frame 2 stops moving. The arc-shaped structural design of the positioning concave shaft 7 and the positioning telescopic shaft 8 facilitates the insertion of the positioning telescopic shaft 8 into the positioning concave shaft 7. Through the structural design of the positioning concave shaft 7 and the positioning telescopic shaft 8, accurate mold movement is achieved without the need for manual pushing and pulling to correct the position. This allows the mold to quickly enter the workstation inside the frame 1, achieving rapid and accurate mold movement, improving production efficiency. The structure is ingenious and highly practical.

[0025] In a specific embodiment, refer to Figure 1 , Figure 5 and Figure 7One end of the rotating arm 6 is provided with a hook mold holder shaft 62, and the mold frame 2 is provided with a shaft hole 21. The inner diameter of the shaft hole 21 is larger than the outer diameter of the hook mold holder shaft 62, and the hook mold holder shaft 62 can be detachably installed in the shaft hole 21. Further, the outer diameter of the hook mold holder shaft 62 gradually decreases in the direction away from the rotating arm 6. Specifically, when the hook mold holder shaft 62 is located below the shaft hole 21, the outer diameter of the end of the hook mold holder shaft 62 closest to the shaft hole 21 is smaller than the outer diameter of the end installed on the rotating arm 6, so as to facilitate the installation of the hook mold holder shaft 62 in the shaft hole 21. (Reference) Figure 7 The mold frame 2 is provided with several guide wheel mounting parts 22 arranged along the extension direction of the first guide rail 31 and the second guide rail 11. The guide wheel mounting parts 22 are used to install guide wheels to ensure that the mold frame 2 runs stably on the first guide rail 31 and the second guide rail 11.

[0026] The working principle of the automatic mold moving device proposed in this application is explained below.

[0027] During the mold transfer process into frame 1, mold frame 2 is located in the second position on mold transfer support frame 3. The mold is placed inside mold frame 2, and slider 34 moves along guide rod 36 to abut against positioning block 35. The hooking shaft 62 of rotating arm 6 is located below shaft hole 21 of mold frame 2. Mold transfer support frame 3 is moved upward, which in turn drives guide rod 36, slider 34, fixed seat 32 connected to slider 34, and rotating arm 6 connected to fixed seat 32 to move upward, so that hooking shaft 62 is installed in shaft hole 21, and the first guide rail 31 on mold transfer support frame 3 aligns with the second guide rail 11 inside frame 1. Linear drive mechanism 4 starts working, cylinder 41 drives piston rod 42 to extend, driving rack 52 forward to rotate gear 51, thereby driving rotating arm 6 to rotate, so that mold frame 2 moves from the second position toward the first position inside frame 1. Then the mold moving support frame 3 is moved downward to drive the hook mold frame shaft 62 to move downward and disengage from the shaft hole 21. The linear drive mechanism 4 drives the rotating arm 6 to rotate, so that the rotating arm 6 moves out of the frame 1.

[0028] During the mold removal process from frame 1, the mold transfer support frame 3 is moved upwards. Before the first guide rail 31 on the mold transfer support frame 3 aligns with the second guide rail 11 inside frame 1, the linear drive mechanism 4 drives the rotating arm 6 to rotate via the reversing mechanism 5. This causes the hook mold frame shaft 62 on the rotating arm 6 to move towards the inside of frame 1 until the hook mold frame shaft 62 is located below the shaft hole 21 of the mold inside frame 1. The mold transfer support frame 3 continues to move upwards until the hook mold frame shaft 62 is installed in the shaft hole 21, and the first guide rail 31 aligns with the second guide rail 11. Then, the linear drive mechanism 4 drives the rotating arm 6 to rotate via the reversing mechanism 5, causing the mold frame 2 to move on the second guide rail 11 and the first guide rail 31. The mold frame 2 and the mold inside the mold frame 2 move from the first position towards the second position.

[0029] The automatic mold moving device proposed in this application realizes automated operation, quickly moving the mold into the workstation inside the frame 1 without manual pushing or pulling, and the mold moving position is accurate, achieving the purpose of fast and accurate mold moving, improving production efficiency, reducing the workload of workers, saving human resources, and improving equipment safety.
