[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-5A rubber bottle cap shaping device includes a base plate 1, four symmetrically distributed limiting rods 3 are fixedly connected to the upper end face of the base plate 1, a top plate 2 is fixedly connected to the upper end face of the four limiting rods 3, a sliding plate 4 is slidably connected to the outer wall of the four limiting rods 3, an upper mold 6 is installed on the lower end face of the sliding plate 4, a fixed frame 7 is fixedly connected to the outer wall of the four limiting rods 3, a lower mold 8 is arranged between the inner walls of the fixed frame 7, a flipping discharge mechanism and two symmetrically distributed cooling and shaping mechanisms are arranged on the outer wall of the fixed frame 7, the cooling and shaping mechanism includes a second rotating shaft 16 rotatably connected to the upper side of the fixed frame 7 through an ear plate 15, two connecting rods 17 fixedly connected to the outer wall of the second rotating shaft 16, a wind box 18 fixedly connected to the other end of the two connecting rods 17, a fan 21 installed on the upper end face of the wind box 18, a plurality of evenly distributed through holes 20 are opened on the lower end face of the wind box 18, and the air outlet of the fan 21 is connected to the wind box 18.

[0026] The cooling and shaping mechanism also includes a gear 22 fixedly connected to the outer wall of the second rotating shaft 16 and a rack 23 fixedly connected to the rear end face of the slide plate 4, with the gear 22 and the rack 23 meshing together.

[0027] In this embodiment: the first electric push rod 5 is activated, which drives the slide plate 4 to slide downward along the limiting rod 3, thereby driving the upper mold 6 to move downward and close with the lower mold 8 to inject the bottle cap. When the slide plate 4 moves downward, it drives the rack 23 to move downward, thereby driving the gear 22 to rotate. The gear 22 further drives the second rotating shaft 16 to rotate, thereby driving the bellows 18 to rotate to both sides through the connecting rod 17 to prevent the bellows 18 from blocking the downward movement of the upper mold 6. After the injection molding is completed, the first electric push rod 5 drives the slide plate 4 to move upward, thereby driving the upper mold 6 to separate from the lower mold 8. When the slide plate 4 moves upward, it drives the rack 23 to move upward, thereby driving the gear 22 to rotate in the opposite direction. The gear 22 further drives the second rotating shaft 16 to rotate in the opposite direction, thereby driving the bellows 18 to rotate towards the center through the connecting rod 17, so that the bellows 18 rotates above the lower mold 8. The blower 21 is activated, and the blower 21 blows air into the bellows 18 and blows it downward through multiple through holes 20 onto the rubber bottle cap inside the lower mold 8, which quickly cools and shapes the rubber bottle cap, resulting in high production efficiency.

[0028] As a technical optimization of this utility model, the flipping and discharging mechanism includes two first rotating shafts 9 fixedly connected to the front and rear end faces of the lower mold 8 and rotatably connected to the fixed frame 7. A sliding groove 10 is provided on the outer wall of the first rotating shaft 9 on the front side, and two circumferentially distributed spiral grooves 11 are provided through the outer wall of the first rotating shaft 9 on the front side. The flipping and discharging mechanism also includes a second electric push rod 12 installed on the front end face of the fixed frame 7. The output end of the second electric push rod 12 is fixedly connected to a connecting shaft 13 that is slidably connected to the sliding groove 10. Two short columns 14 that are slidably connected to the spiral grooves 11 are fixedly connected to the outer wall of the connecting shaft 13.

[0029] In this embodiment: the second electric push rod 12 is activated, and the second electric push rod 12 drives the connecting shaft 13 to slide into the slide groove 10, which in turn drives the first rotating shaft 9 to rotate through the short column 14 and the spiral groove 11. The first rotating shaft 9 further drives the lower mold 8 to rotate, so that the lower mold 8 rotates 180°, thereby facilitating the downward pouring of the rubber bottle cap in the lower mold 8, making the discharge convenient.

[0030] As a technical optimization of this utility model, the spiral groove 11 has 0.5 turns.

[0031] In this embodiment, by setting the number of turns of the spiral groove 11 to 0.5 turns, it is easier to drive the lower mold 8 to rotate 180°.

[0032] As a technical optimization of this utility model, a collection box 19 is provided on the upper surface of the base plate 1.

[0033] In this embodiment, a collection box 19 is provided on the upper surface of the base plate 1 to facilitate the collection of rubber bottle caps.

[0034] As a technical optimization of this utility model, the second electric actuator 12 is an anti-self-rotation electric actuator.

[0035] In this embodiment: by setting the second electric actuator 12 as an anti-self-rotation electric actuator, the axial rotation of the connecting shaft 13 is prevented.

[0036] As a technical optimization of this utility model, a first electric push rod 5 is installed on the upper surface of the top plate 2, and the output end of the first electric push rod 5 extends to the bottom of the top plate 2 and is fixedly connected to the slide plate 4.

[0037] In this embodiment, the first electric actuator 5 facilitates the up-and-down movement of the slide plate 4.

[0038] As a technical optimization of this utility model, a controller is provided on the outer wall of the fixed frame 7, and the first electric push rod 5, the second electric push rod 12 and the fan 21 are all electrically connected to the controller.

[0039] In this embodiment, the controller facilitates the normal operation of the first electric actuator 5, the second electric actuator 12, and the fan 21.

[0040] The working principle and usage process of this utility model are as follows: First, the first electric actuator 5 is activated. The first electric actuator 5 drives the slide plate 4 to slide downwards along the limiting rod 3, thereby causing the upper mold 6 to move downwards and close with the lower mold 8 to inject the bottle cap. When the slide plate 4 moves downwards, it drives the rack 23 to move downwards, which in turn drives the gear 22 to rotate. The gear 22 further drives the second rotating shaft 16 to rotate, which in turn drives the bellows 18 to rotate to both sides via the connecting rod 17, preventing the bellows 18 from blocking the downward movement of the upper mold 6. After injection molding, the first electric actuator 5 drives the slide plate 4 to move upwards, thereby causing the upper mold 6 to separate from the lower mold 8. When the slide plate 4 moves upwards, it drives the rack 23 to move upwards, which in turn drives the gear 22 to rotate in the opposite direction. Gear 22 further drives the second rotating shaft 16 to rotate in the opposite direction, which in turn drives the bellows 18 to rotate towards the center through connecting rod 17, so that the bellows 18 rotates above the lower mold 8. Then, the blower 21 is started, and the blower 21 blows air into the bellows 18 and blows it downwards onto the rubber bottle caps in the lower mold 8 through multiple through holes 20, which quickly cools and shapes the rubber bottle caps, resulting in high production efficiency. After cooling and shaping, the second electric push rod 12 is started, which drives the connecting shaft 13 to slide into the slide groove 10, which in turn drives the first rotating shaft 9 to rotate through the short column 14 and the spiral groove 11. The first rotating shaft 9 further drives the lower mold 8 to rotate, so that the lower mold 8 rotates 180°, which makes it easier to pour the rubber bottle caps in the lower mold 8 downwards, making material discharge convenient.
