For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0029] like Figure 1 , Figure 2 , Figure 4 , Figure 8 , Fig.10 As shown, a flexible injection mold includes a first main body 1, a first liner 2, a second liner 3 and a second main body 4. The first main body 1 and the second main body 4 are arranged opposite to each other, and the side walls close to each other are respectively provided with a first filling groove 11 and a second filling groove 41. The first liner 2 is connected by bolts and can be detachably arranged in the first filling groove 11. The second liner 3 is connected by a connecting mechanism 5 and can be detachably arranged in the second filling groove 41. The first injection cavity 21 and the second injection cavity 34 are respectively arranged on the side walls adjacent to each other of the first liner 2 and the second liner 3. The second injection cavity 34 is communicated with the first injection cavity 21 to form an injection space. In addition, a feed hole is provided on the side wall of the first filling groove 11, and the feed hole is located on the inner side of the first injection cavity 21. When the injection mold is used to process plastic products, the injection mold is installed on the injection molding machine body. Specifically, the first body 1 is installed at the end of the injection molding machine body, and the second body 4 is movably arranged on the side of the injection molding machine body. Since the injection molding equipment is a prior art, the way in which the injection mold composed of the first body 1 and the second body 4 is installed on the injection molding machine body has been disclosed, and will not be described in detail here. After the injection mold is installed on the injection molding machine body, the injection molding machine body heats the plastic raw material, and controls the molten plastic raw material to move to the end of the injection molding machine body. At the same time, under the action of high pressure, the molten plastic raw material passes through the feed hole into the injection molding space. Finally, due to cooling, the plastic raw material in the injection molding space solidifies and forms. After forming, the second body 4 moves relative to the first body 1, so that the product is exposed and separated from the second lining 3, and the processing of the product is completed. When producing products of different models, shapes, and patterns, the staff only needs to disassemble and replace the first lining 2 and the second lining 3, which changes the current situation that multiple sets of injection molds need to be equipped at the same time and the entire injection mold needs to be replaced to achieve the production of different products, improves the flexibility of the injection mold, and reduces the cost of injection molding production.

[0030] like Figure 2 , Figure 3As shown in the figure, in order to achieve the disassembly and assembly of the first inner liner 2 relative to the first main body 1, a first ear plate is provided at the end of the first main body 1. At the same time, a sealing groove 12 is provided on the side wall of the first filling groove 11. The sealing groove 12 is arranged outside the feed hole. A sealing convex plate 22 is provided on the side surface of the first inner liner 2, and a second ear plate is fixedly provided at the end. A bolt is passed through the second ear plate, and the end of the bolt is threadedly inserted into the first ear plate. At the same time, the sealing convex plate 22 is inserted into the sealing groove 12. With the cooperation of the sealing convex plate 22 and the sealing groove 12, the first injection cavity 21 communicates with the feed hole.

[0031] As Figure 1 , Fig. 9 shown in the figure, in order to achieve the disassembly and assembly of the first inner liner 2 relative to the second main body 4, a connecting mechanism 5 is provided at the ends of the second inner liner 3 and the second main body 4. The connecting mechanism 5 includes a main board 51, a sleeve board 52 and an adjusting screw 53. The main board 51 is hinged to the second main body 4, and a buckle groove is provided on the side wall. The sleeve board 52 is arranged in a U-shaped structure, and a buckle post is fixedly provided on the inner side wall. The sleeve board 52 is sleeved on the end of the main board 51, and the buckle post is located in the buckle groove. The adjusting screw 53 passes through the sleeve board 52, and the end of the adjusting screw is threadedly inserted into the main board 51. An insertion rod 54 is fixedly provided below the sleeve board 52, and the insertion rod 54 is inserted into the insertion slot 33 of the second inner liner 3. The diameter of the insertion slot 33 is larger than the diameter of the insertion rod 54. After the insertion rod 54 is inserted into the insertion slot 33, the worker rotates the adjusting screw 53 to control the movement of the sleeve board 52 relative to the main board 51, forcing the first inner liner 2 to be closely attached to the second main body 4. When it is necessary to disassemble and replace the second inner liner 3, the adjusting screw 53 is rotated in the reverse direction to move the sleeve board 52 away from the main board 51, and the sleeve board 52 and the main board 51 are controlled to rotate around the axis. At the same time, the insertion rod 54 is disengaged from the insertion slot 33, releasing the restriction of the second inner liner 3 and the second main body 4.

[0032] As Figure 7 shown in the figure, in order to reduce the weight of the second inner liner 3, the middle part of the side wall of the second inner liner 3 away from the first inner liner 2 is provided with a hollow structure, and the hollow structure is located inside the second injection cavity 34, thereby reducing the labor intensity of the worker when moving the second inner liner 3.

[0033] As Figure 6 , Figure 7As shown, in order to accelerate the cooling of the product, a cooling bin 32 is provided on the side wall of the second liner 3 away from the first liner 2. The cooling bin 32 is provided on the outside of the hollow structure and communicated with the hollow structure. In addition, a blocking plate 6 is provided at the cooling bin 32. A liquid bin 61 is provided at the end of the blocking plate 6. A delivery pipe 62 is provided below the liquid bin 61. The delivery pipe 62 is connected to a liquid pump. Under the action of the liquid pump, the coolant flows through the delivery pipe 62 and the liquid bin 61 to the cooling bin 32 and the hollow structure to cool the second liner 3, thereby accelerating the molding of the product. The heated coolant is output from another liquid bin 61 and the delivery pipe 62 to achieve circulating cooling of the second liner 3.
