[0033] Furthermore, an annular groove 51 is provided at the top of the mold base 5 near the outer side of the cup mold 7 for providing movement of the extrusion ring 58, and the extrusion ring 58 slides on the inner wall of the annular groove 51. A through groove 59 is provided at the top of the mold base 5 near the inner wall of the annular groove 51 for providing movement of the guide block 52. The bottom end of the extrusion ring 58 is fixedly connected to the guide block 52 for driving the extrusion ring 58 to move, and the guide block 52 passes through and is slidably connected to the inner wall of the through groove 59.

[0034] Reference Figure 2 , Figure 3 , Figure 5 A disassembly and assembly component is provided on the left side of the side mold 2 to increase the convenience of disassembly and assembly. The disassembly and assembly component includes a card block 31 for providing support. The card block 31 is fixedly installed on the left side of the side mold 2. A circular groove 32 is provided on the front surface of the card block 31. A positioning frame 3 for providing support is fixedly connected to the right side of the elastic telescopic rod 4. A round rod 33 passes through and is slidably connected to the front surface of the positioning frame 3. The round rod 33 slides into the circular groove 32 to limit the card block 31 and the side mold 2.

[0035] Reference Figure 2 , Figure 3 , Figure 4The left side of the bottom end of the guide block 52 is fixedly connected with a guide rod 54 for driving the guide block 52 to move up and down. The front surface of the base 6 is slidably connected with a pull plate 55 for driving the connecting plate 57 and the guide frame 53 to move. The pull plate 55 is elastically connected to the base 6 through a spring 2 56. Pulling the pull plate 55 stretches the spring 2 56 to drive the connecting plate 57 and the guide frame 53 to move. The connecting plate 57 and the guide frame 53 are slidably connected to the inner wall of the guide frame 53 through the guide rod 54. At the same time, the guide rod 54 can only move up and down in conjunction with the guide block 52, so that the guide frame 53 can be moved by tilting, so that the guide rod 54 moves up and down, thereby driving the guide block 52 and the extrusion ring 58 to move, so that the injection-molded cup can be lifted up by the extrusion ring 58, thereby further improving the demoulding efficiency.

[0036] Furthermore, a connecting plate 57 is fixedly connected to the rear surface of the pull plate 55 for supporting the guide frame 53 and connecting the pull plate 55 to the guide frame 53. The guide frame 53 is fixedly connected to the rear surface of the connecting plate 57. The guide rod 54 is slidably connected to the inner wall of the guide frame 53. The guide frame 53 is arranged in an inclined shape. The guide rod 54 is slidably connected to the inclined inner wall of the guide frame 53. Therefore, when the guide frame 53 moves, the guide rod 54 can be moved up and down through the inclined surface, thereby driving the guide block 52 and the extrusion ring 58 to move, so that the injection-molded cup can be lifted up through the extrusion ring 58, thereby further improving the demolding efficiency. The guide frame 53, the connecting plate 57, the guide rod 54, and the guide block 52 are all slidably connected to the inner wall of the base 6.

[0037] Reference Figure 2 , Figure 3 , Figure 5 The rear end outer wall of the round rod 33 is fixedly connected with a round block 35, which supports the round rod 33 and the spring 34 through the round block 35, and the round block 35 is slidably connected to the front inner wall of the positioning frame 3, and the round block 35 is elastically connected to the positioning frame 3 through the spring 34, and the spring 34 is sleeved on the outer wall of the round rod 33. The top of the rear end of the round rod 33 is set as an inclined surface, and the inclined surface of the round rod 33 is squeezed when the block 31 slides into the inner wall of the positioning frame 3, so that the round rod 33 moves and drives the round block 35 to move and squeeze the spring 34. When the block 31 slides to the bottom end of the positioning frame 3, the circular groove 32 is aligned with the circular rod 33. At this time, the reverse force squeezed by the spring 34 can drive the round rod 33 to reset, so that the round rod 33 slides into the circular groove 32, and the block 31 can be quickly limited by the side mold 2, so that the installation is more convenient, the block 31 slides on the right side of the positioning frame 3, and the round rod 33 slides on the inner wall of the circular groove 32.

[0038] Working principle: when in use, the side mold 2 is moved to drive the block 31 to move and slide into the positioning frame 3. After the block 31 squeezes the inclined surface of the round rod 33, the round rod 33 moves and drives the round block 35 to move and squeeze the spring 34. When the block 31 completely slides into the positioning frame 3, the circular groove 32 is aligned with the round rod 33. At this time, the reverse force of the squeezing of the spring 34 can drive the round rod 33 to reset, so that the round rod 33 slides into the circular groove 32 to quickly limit the block 31 and the side mold 2. There is no need to use bolts to install it inside the mold body 1, which makes the installation more convenient and convenient to replace different molds for processing. When dismantling is required, the round rod 33 can be directly pulled out of the circular groove 32 to release the limit of the block 31, and the side mold 2 can be quickly removed and replaced, thereby improving applicability.

[0039] By injection molding the cup, when the injection molding is completed and the cup is cooled, the pull plate 55 can be pulled to stretch the spring 56 to drive the connecting plate 57 and the guide frame 53 to move. The guide frame 53 moves so that the guide rod 54 slides on the inner wall of the guide frame 53. The guide frame 53 is set to be inclined so that the guide rod 54 can slide upward to drive the guide block 52 and the extrusion ring 58 to move. The extrusion ring 58 moves to lift up the cup that has been injection molded above, thereby reducing the friction between the cup and the cup mold 7. At this time, the lifted cup can be easily taken out, thereby further improving the convenience of demoulding and improving the processing efficiency.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
