The top of the mounting ring 5 and the top of the top ring 6 are threadedly connected with a plurality of fixing bolts 10. A limit assembly is arranged at the top of the top ring 6 and outside the fixing bolts 10. When installing the mounting ring 5, the mounting ring 5 is inserted into the inner side of the movable bottom mold 3, and the top ring 6 and the movable bottom mold 3 are fixed by the fixing bolts 10, thereby playing a fixing effect on the mounting ring 5. When the mold is used for injection molding, the motor can be enlarged, the screw can be reduced, and the shooting speed can be increased, which is 3 times the shooting speed of an ordinary injection molding machine, so that the injection molding can be completed directly, saving time and reducing costs.

[0036] The limiting assembly includes a rotating snap ring 9, which is rotatably connected to the top of the top ring 6, and a fixing bolt 10 is inserted into the inner side of the rotating snap ring 9. A snap ring 7 is fixed to the top of the top ring 6 and located on the outer side of the rotating snap ring 9 through a plurality of screws 13, and a snap ring 7 is provided on the inner side of the snap ring 7 with snap teeth 8 corresponding to the rotating snap ring 9. The snap teeth 8 have the same shape as the teeth on the rotating snap ring 9 and face in the opposite direction. Through this arrangement, the snap teeth 8 can clamp the rotating snap ring 9, and the rotating snap ring 9 will not be stuck when it rotates forward. A synchronous rotation structure is installed on the fixing bolt 10 and the rotating snap ring 9.

[0037] The synchronous rotation structure is used to make the rotating retaining ring 9 and the fixing bolt 10 rotate synchronously. The synchronous rotation structure includes an inclined surface 11, which is arranged on the outer side of the fixing bolt 10. The inner side of the rotating retaining ring 9 is provided with a convex surface 12 corresponding to the inclined surface 11. Through this arrangement, the convex surface 12 can limit the inclined surface 11, so that the rotating retaining ring 9 can be driven to rotate synchronously when the fixing bolt 10 rotates. The clamping ring 7 is fixed to the top of the top ring 6 by screws 13, and the fixing bolt 10 is inserted into the inner side of the rotating retaining ring 9. The fixing bolt 10 is rotated, so that the fixing bolt 10 drives the rotating retaining ring 9 to rotate synchronously through the inclined surface 11 and the convex surface 12. When rotating, the rotating retaining ring 9 can be rotated in the forward direction but not in the reverse direction by setting the rotating retaining ring 9 and the clamping teeth 8, thereby ensuring that the fixing bolt 10 will not gradually loosen when the mold vibrates.

[0038] See also Figure 4-5 The mounting ring 5 includes a mounting ring 51, a heating wire 52, a connecting heat absorbing plate 53 and a heat insulating plate 54. The inner side of the mounting ring 51 is wrapped with the heating wire 52. The side of the mounting ring 51 close to the mounting mold groove 4 is provided with a connecting heat absorbing plate 53. The side of the mounting ring 51 away from the mounting mold groove 4 is provided with a heat insulating plate 54. The thickness of the heat insulating plate 54 is greater than the thickness of the connecting heat absorbing plate 53. The heat insulating plate 54 can isolate most of the heat, thereby ensuring that the overall temperature of the mold is not too high, thereby improving the service life of the mold. By starting the heating wire 52, the heating wire 52 emits heat, and then the heat of the heating wire 52 extends to the inner side of the mounting mold groove 4 through the connecting heat absorbing plate 53, heating the product to prevent it from sticking to the mold. The setting of the heat insulating plate 54 can isolate most of the heat emitted to the outside, thereby protecting the mold.

[0039] See also Figure 8-9A vent groove 20 is provided on the inner side of the movable bottom mold 3 and at the bottom of the mounting mold groove 4. A sealing plate 14 is slidably connected to the inner side of the vent groove 20 and at a position corresponding to the mounting mold groove 4. The sealing plate 14 is made of a flexible material. Through the setting of the material of the sealing plate 14, the sealing plate 14 can enter the inner side of the vent groove 20 without getting stuck, and the sealing plate 14 can have a better sealing effect. A fixing column 15 is fixed to the bottom of the sealing plate 14. A spacer plate 16 is provided inside the movable bottom mold 3 and at the inner side of the vent groove 20. The fixing column 15 is slidably connected to the spacer plate 16. The bottom of the fixing column 15 is installed There is a connecting block 17, and a fixed block 18 is installed on the inner side of the air groove 20 and directly below the connecting block 17. A spring 19 is installed between the fixed block 18 and the connecting block 17. Through the setting of the sealing plate 14, the sealing plate 14 can be level with the movable bottom mold 3 at normal times. When the user takes the product, the product rises with a certain pressure, and a vacuum-like space is formed on the inner side of the mounting mold groove 4. At this time, the sealing plate 14 rises, the spring 19 is stretched, and the air enters the inner side of the mounting mold groove 4 through the air groove 20. After taking the product, the sealing plate 14 rebounds through the setting of the spring 19, and the next raw material can be placed.

[0040] Working principle: When the user uses the device, the plastic raw material is melted at high temperature and then injected into the inner side of the mounting mold groove 4. The top mold on the inner side of the mounting frame 2 and the movable bottom mold 3 cooperate to shape the raw material on the inner side of the mounting mold groove 4 and then undergo subsequent processing to form a finished product. When the product needs to be taken out, the movable bottom mold 3 can be moved out and the product can be taken out directly. When taking it out, the heating wire 52 can be started to emit heat, and then the heat of the heating wire 52 can be extended to the inner side of the mounting mold groove 4 through the connecting heat absorbing plate 53 to heat the product and prevent it from sticking to the mold. The setting of the heat insulation plate 54 can isolate most of the heat dissipated to the outside, thereby protecting the mold.

[0041] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
