[0030] This invention provides an injection molding machine for perfume bottle manufacturing that allows for rapid cooling and demolding, such as... Figure 1-9As shown, the machine includes a workbench 1, a frame 2 fixedly installed on the left side of the workbench 1, a lower mold 4 arranged on the top of the workbench 1, an upper mold 5 laid on the top of the lower mold 4, and a cylinder 21 fixedly installed on the frame 2. The movable end of the cylinder 21 is vertically downward, and when the cylinder 21 is extended, it can contact the top of the upper mold 5.

[0031] The lower mold 4 has a bottle body cavity 41 and an outer cavity 42 inside. The upper end of the bottle body cavity 41 is vertically upward and connected to the outside. The outer cavity 42 surrounds the bottle body cavity 41, and an ultrasonic vibration module 43 is fixedly installed inside the outer cavity 42. A switch and a battery are also fixedly installed on the outside of the lower mold 4. The switch and battery are electrically connected to the ultrasonic vibration module 43.

[0032] The ultrasonic vibration module 43 mentioned above is existing technology. Its specific structure, circuit layout, and connection method are the same as conventional technical means, so it will not be described in detail.

[0033] When the ultrasonic vibration module 43 is activated, it can cause the inner wall of the bottle cavity 41 to vibrate slightly at a high frequency.

[0034] It also includes a rotating roller 10, which is pivotally connected to an outer sleeve 102. The rotating roller 10 is capable of rotating around its center. The outer sleeve 102 is snapped onto the top of the lower mold 4, and the rotating roller 10 is located directly above the bottle cavity 41. The bottom of the rotating roller 10 has a vertical section 101 that extends into the bottle cavity 41.

[0035] A cylinder 103 is welded to the top of the rotating roller 10, and an air pipe 7 is connected to the side of the outer sleeve 102. The air pipe 7 extends from between the lower mold 4 and the upper mold 5. A bottle cap groove 51 is opened at the bottom of the upper mold 5, and the cylinder 103 is located in the bottle cap groove 51.

[0036] The distance between each inner wall surface of the bottle cap groove 51 and the cylinder 103 is the same.

[0037] The upper mold 5 has an injection hole 54 and an air hole 55 on its top. The lower ends of the injection hole 54 and the air hole 55 are connected to the bottle cap groove 51. The frame 2 is connected to an injection mechanism, which can dock with the injection hole 54.

[0038] The lower mold 4 consists of two semi-circular truncated cones. A water pipe 6 is fixedly installed on one side of the semi-circular truncated cones that are far apart from each other. The water pipe 6 is connected to the outer cavity 42. A through hole 105 is opened on the side of the outer sleeve 102. A Y-shaped channel 106 is opened inside the rotating roller 10. The converging end of the Y-shaped channel 106 passes vertically downward through the vertical section 101. The branch ends of the Y-shaped channel 106 are connected to the through hole 105. The air pipe 7 is connected to the through hole 105.

[0039] A toothed ring 104 is welded to the top of the rotating roller 10 and outside the cylinder 103. A motor 52 is fixedly installed at the bottom of the upper mold 5. A gear 53 is welded to the drive shaft of the motor 52, and the gear 53 can mesh with the toothed ring 104. A switch and a battery are also fixedly installed outside the upper mold 5, and the switch and battery are electrically connected to the motor 52.

[0040] Combined with appendix Figure 8 As can be seen, when the upper mold 5 and the lower mold 4 are fixed together, the cap groove 51 is sealed by the toothed ring 104. Therefore, the molten material will not leak out during the injection molding process.

[0041] A miniature electric actuator 107 is fixedly installed inside the cylinder 103. The movable end of the miniature electric actuator 107 extends outside the cylinder 103, and a cutter 108 is fixedly installed at the movable end of the miniature electric actuator 107. A control module, a WiFi module, and a battery are also fixedly installed inside the cylinder 103. The control module, WiFi module, and battery are electrically connected to the miniature electric actuator 107. The extension or retraction of the miniature electric actuator 107 can be controlled remotely.

[0042] In the non-working state, the miniature electric actuator 107 is retracted, and the cutter 108 is hidden inside the cylinder 103. When working, the miniature electric actuator 107 extends, and the cutter 108 extends out from the cylinder 103, allowing the cutter 108 to contact the inner wall of the bottle cap.

[0043] The workbench 1 has a slide groove 11 on its top, and a slider 8 is welded to the bottom of the semi-circular platform. The slider 8 slides in conjunction with the slide groove 11. The lower mold 4 has a positioning plug 9 on its side. The two ends of the positioning plug 9 are inserted into the two semi-circular platforms respectively. The positioning plug 9 is welded with handles 91. The two semi-circular platforms are fixed together by the positioning plug 9.

[0044] Combined with appendix Figure 8 The upper end of the bottle body cavity 41 is provided with a straight end, and the inner wall of the straight end is provided with a recess 45 that is adapted to the tool 108. The recess 45 is used to create a protrusion on the bottle body, and the tool 108 is used to create a fastening groove in the bottle cap. By the cooperation of the protrusion and the fastening groove, the bottle cap and the bottle body opening can be fastened together.

[0045] Working principle: Move the two semicircular platforms closer to each other, and use the positioning plug 9 to merge the two semicircular platforms to form the lower mold 4. Then, put the heated preform on the outside of the vertical section 101 of the rotating roller 10, and put the outer sleeve 102 on the top of the lower mold 4. The vertical section 101 and the preform are inserted into the bottle cavity 41 together.

[0046] The upper mold 5 is fixedly installed on the lower mold 4. Air is introduced into the Y-shaped channel 106 through the air pipe 7. The preform is expanded by blowing air until it contacts the inner wall of the bottle cavity 41. The recess 45 is used to create a convex shape on the straight section of the bottle body.

[0047] Next, the molten material is injected into the cap groove 51 through the injection hole 54. A water pipe 6 on one side of the cold water mold 4 is introduced into the outer cavity 42, and then exited from the other side of the water pipe 6. This accelerates the cooling of the blow-molded preform. The ultrasonic vibration module 43 is activated to cause slight vibration of the inner wall of the bottle cavity 41, causing the inner wall of the bottle cavity 41 to detach from the preform.

[0048] Before the bottle cap has cooled down, the micro electric push rod 107 is extended, causing the cutter 108 to extend. The motor 52 drives the gear 53 to rotate, and the gear 53 drives the entire rotating roller 10 to rotate through the gear ring 104, so that a matching groove is formed on the inner side of the bottle cap.

[0049] Finally, after the bottle cap has cooled down, the cylinder 21 retracts and no longer presses against the upper mold 5. The upper mold 5 is lifted upwards, and since the cutter 108 is embedded in the bottle cap locking groove, the cutter 108 pulls the bottle cap out of the bottle cap groove 51. After removing the rotating roller 10 and the positioning plug 9, the handles 44 on both sides of the lower mold 4 are pulled to separate the lower mold 4 and remove the bottle body.

[0050] The material injection mechanism includes a material conveying module 3, a connecting pipe 31, and an injection nozzle 32. The material conveying module 3 is fixedly installed together with the frame 2, and the material conveying module 3 and the injection nozzle 32 are connected together through the connecting pipe 31. The movable end of the cylinder 21 is fixedly installed with the injection nozzle 32, and the injection nozzle 32 can mate with the injection hole 54.

[0051] When the cylinder 21 extends to its longest length, the injection nozzle 32 extends into the injection hole 54, and the lower end of the cylinder 21 presses against the upper mold 5.

[0052] An air pump 12 is fixedly installed on the top of the workbench 1, and the working end of the air pump 12 can be connected to the air pipe 7.

[0053] In summary, this injection molding machine for perfume bottle manufacturing, which enables rapid cooling and demolding, comprises a lower mold 4, an upper mold 5, a rotating roller 10, an outer casing 102, and a cylinder 103, which work together to produce the perfume bottle body and cap respectively. The bottle body cavity 41 is enclosed by an outer cavity 42, which contains an ultrasonic vibration module 43. The ultrasonic vibration module 43 vibrates the inner wall of the bottle body cavity 41, achieving the effect of separating the preform from the inner wall of the bottle body cavity 41. This facilitates demolding and bottle removal. A micro electric push rod 107 and a cutter 108 work together to create a locking groove inside the cap, and the cutter 108 uses this to hook the cap out of the cap groove 51, preventing jamming during demolding.
