[0002] Injection molds are commonly used molds for molding plastic parts. They are tools that give plastic products a complete structure and precise dimensions. Through injection molds, a variety of plastic parts can be molded to meet people's various production and life needs. When an injection mold is working, it refers to injecting molten plastic into the mold cavity under high pressure from an injection molding machine. After cooling and solidification, the molded product is obtained.

[0003] Many injection molds require precision machining and surface treatment during manufacturing, often necessitating flipping to process the other side as well. Currently, mold flipping is mostly done manually. However, injection molds are often made of alloy steel, and even small molds are quite heavy, making mold flipping extremely inconvenient, unsafe, time-consuming, and labor-intensive. Furthermore, flipping them can easily damage the mold.

[0004] Therefore, it is necessary to propose an easy-to-operate circular mold flipping and hoisting device. Utility Model Content

[0023] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: As Figures 1-3 As shown, a circular mold flipping and hoisting device includes a lifting lug 1, a lifting rod 2, and a support plate 3. Two lifting chains 4 are connected to the lifting lug 1, and the bottom ends of the two lifting chains 4 are respectively connected to the top ends of the two lifting rods 2. The upper parts of the lifting rods 2 are rotatably connected in a cross manner, and the lower parts of the lifting rods 2 are bent and connected to a base 5. An elastic element is connected between the upper part of one lifting rod 2 and the lower part of the other lifting rod 2. The support plate 3 is rotatably connected to the base 5. The opposing ends of the two support plates 3 are open, and at least two stop bars 6 are connected to each support plate 3.

[0025] The lifting lug 1 is elongated, and the bottom end of the lifting chain 4 is connected to the shackle 7. The top end of the lifting rod 2 is provided with a through hole, and the shackle 7 is connected to the through hole.

[0026] The angle between the upper and lower parts of the boom 2 is an obtuse angle. The upper part of one boom 2 is connected to the sleeve 9, and the other boom 2 passes through the sleeve 9. A pin passes through the sleeve 9 and the boom 2 so that the boom 2 is rotatably connected to the sleeve 9.

[0027] The elastic element is spring 8. The upper part of the rod 2 is connected to ear rod A10, and the lower part of the rod 2 is connected to ear rod B11. The two ends of spring 8 are connected to ear rod A10 and ear rod B11 respectively through hooks.

[0028] The base 5 has a threaded hole in the lateral position. The screw 12 is threaded into the threaded hole and extends out of the inner end of the base 5. The inner end of the screw 12 is a smooth rod and is connected to a baffle 13.

[0029] The pallet 3 includes an upper plate, a lower plate, and a back plate. The upper plate and the lower plate are in a trapezoidal structure. One end of the upper plate and the lower plate are respectively connected to the upper and lower ends of the back plate to form an open cavity for accommodating the workpiece. The back plate is rotatably connected to the smooth rod part of the inner end of the screw 12.

[0030] The upper and lower ends of the stop lever 6 are connected to the upper plate and the lower plate, respectively.

[0031] Example 2: This example is a further improvement on Example 1. The main improvement is that in Example 1, the workpiece surface is at risk of being worn by the stop bar 6 during operation; however, in this example, the above-mentioned defect can be avoided. Specifically: The outer wall of the stop bar 6 is covered with a soft anti-slip sleeve made of silicone. In this embodiment, the outer wall of the stop bar 6 is covered with a soft anti-slip sleeve to prevent the outer wall of the stop bar 6 from abrading the workpiece.

[0032] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.

[0033] The specific working principle of this utility model is as follows: In this embodiment, the part to be flipped is the circular mold 14. For example... Figure 4 , 5 As shown, the lifting lug 1 of this utility model is hung on the hook of the workshop lifting equipment. During operation, the two support plates 3 move to both sides of the circular mold 14, and the circular mold 14 is inserted into the two support plates 3. The hook of the equipment is lifted upward, and the bottom ends of the two lifting rods 2 move towards each other and clamp the circular mold 14, thereby lifting the circular mold 14. After being lifted, the operator rotates the circular mold 14. When the circular mold 14 is in the vertical position, the stop bar 6 plays a limiting role to prevent it from falling off. After rotating 180°, the circular mold 14 can be lowered.

[0034] In addition, during normal operation, the hoisting device can also be used for hoisting and moving the circular mold 14 in the workshop, as well as to assist in the assembly and disassembly of the circular mold 14 on the CNC machine tool fixture.
