Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Please see Figure 1-3 As shown, this embodiment provides a quick changeover device for lens injection molds, including: a mounting base 1.

[0020] like Figure 1-3 As shown, in this embodiment, a horizontal connecting rod 2 is installed horizontally through the upper part of the mounting base 1, and a vertical connecting rod 3 is installed vertically through the lower part of the mounting base 1. A locking screw is rotatably installed at the center of the mounting base 1. Anti-detachment blocks 4 are provided at both ends of the horizontal connecting rod 2 and the vertical connecting rod 3. A lifting ring seat 5 is provided on the top of the anti-detachment block 4, and a lifting ring 6 is provided on the top of the lifting ring seat 5. The mounting base 1 has holes that are horizontally and vertically through it. The horizontal connecting rod 2 and the vertical connecting rod 3 pass through the mounting base 1. The four mounting bases 1 are connected by connecting rods to form a square. The threaded holes in the center of the mounting base 1 are aligned with the mounting holes of the mold. The locking screw is screwed into the center of the mounting base 1 to fix the device and the mold. The rope passes through the lifting ring seats 5 on both sides of the anti-detachment block 4 and finally converges to the central connection point. Pulling the rope lifts the mold to facilitate subsequent movement and shape change. For different molds, the positioning hole positions are different. The positioning holes are aligned by adjusting the mounting bases on the two connecting rods, so that the mold can be fixed on different molds.

[0021] like Figure 1-3 As shown, in this embodiment, a side clamp 7 is provided on the surface of the longitudinal connecting rod 3 between the mounting bases 1. A slide rod 9 is horizontally installed through the side clamp 7 near the top. A side plate 8 is sleeved on the surface of the slide rod 9. A movable groove 10 is opened at the center of the side plate 8. A slider 11 is installed inside the movable groove 10. Pressure blocks 13 are provided on both sides of the slider 11. The side clamp 7 on the longitudinal connecting rod 3 can move on the longitudinal connecting rod 3. At the same time, the side plate 8 sleeved on the slide rod 9 extending from the side clamp 7 can move on the slide rod 9. The two parts cooperate to adjust the side plate 8. Position the slider 11 so that it fits against the side of the mold. Then adjust the slider 11 inside the side clamp 7 so that the threaded hole on the slider 11 is aligned with the positioning hole on the side of the mold. Screw in the locking screw to install the slider 11 against the side of the mold. Then rotate the locking screws on the pressure blocks 13 on both sides of the slider 11. The locking screws are finally screwed into both sides of the slider 11 to connect with the slider 11. The pressure blocks 13 fit against the movable groove 10 on the side plate 8. The pressure blocks 13 and the side plate 8 are fixed by friction. The side plate 8 is used to assist in the installation and fixation of the device.

[0022] like Figure 3 As shown, racks 12 are provided on both sides of the movable groove 10 in this embodiment; the pressure block 13 that fits the racks 12 is also provided with teeth. When the pressure block 13 is fixed by the locking screw, the two teeth mesh, thereby increasing the friction between the pressure block 13 and the side plate 8 and preventing the slider 11 from moving in the side plate 8 after it is fixed.

[0023] like Figure 1 As shown, in this embodiment, two transverse connecting rods 2 and two longitudinal connecting rods 3 are provided on the same mounting base 1. The two connecting rods are arranged in parallel and inserted into the mounting base 1. Compared with a single connecting rod, the two parallel connecting rods can share the supporting force of the device, making the transverse connecting rod 2 and the longitudinal connecting rod 3 less prone to deformation and able to lift heavier molds.

[0024] like Figure 1 , 2 As shown, the top height of the lifting ring seat 5 on the anti-detachment block 4 in this embodiment is consistent. The lifting ring 6 on the lifting ring seat 5 is installed into the lifting ring seat 5 by rotation. Since the anti-detachment block 4 at the bottom of the lifting ring seat 5 is directly sleeved on the horizontal connecting rod 2 and the vertical connecting rod 3, and the horizontal connecting rod 2 and the vertical connecting rod 3 are at different heights in order to be staggered on the mounting base 1, the height is adjusted by corresponding to the different heights of the two lifting ring seats 5, so that all the lifting rings 6 are at the same height, so that the connection position is consistent when the rope passes through. In this way, the overall center of gravity is located in the middle position, and the mold is not easy to tilt or overturn during transportation.

[0025] like Figure 1-3 As shown, the transverse connecting rod 2 and the longitudinal connecting rod 3 in this embodiment are made of high-strength alloy. In order to ensure the stability of the device during repeated use, the connecting rods need to have higher strength and are made of a higher-strength alloy. When the two ends are lifted, the middle position of the connecting rod can withstand stronger pressure without deformation.

[0026] Working principle: Adjust the position of the four mounting seats 1 on the horizontal connecting rod 2 and the vertical connecting rod 3, align the threaded holes in the center of the mounting seats 1 with the mounting holes on the top of the mold, and screw in the locking screw in the center of the mounting seat 1 to fix the device and the mold. Adjust the position of the side clamp seat 7 on the vertical connecting rod 3, and at the same time move the side plate 8 on the slide rod 9 so that the side plate 8 fits against the side of the mold. Then adjust the position of the slider 11 inside the movable groove 10 until the threaded hole on the slider 11 aligns with the positioning hole on the side of the mold. Screw in the locking screw to fix it from the side, so that the device is completely installed on the mold. Finally, the rope passes through the lifting ring seat 5 on both sides of the anti-detachment block 4 and finally converges to the central connection point, which makes it convenient to lift the mold as a whole for shape change operation.

[0027] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
