Technical Field

[0001] The present invention belongs to the technical field of automotive lamp housing production, and specifically relates to a rapid cooling and shaping device for automotive lamp housings. Background Art

[0002] With the continuous development of society, people's living standards have been continuously improved, and cars have begun to enter the lives of thousands of households. As one of the essential components of a car, the importance of car lights cannot be ignored. Automotive lamp housings are usually formed by injection molding. Molten plastic is injected into the mold cavity under high pressure by an injection molding machine, and after cooling and solidification, a formed product is obtained.

[0003] Traditional mold cooling usually uses a cooling water channel layout. This method is simple and direct, but it has obvious deficiencies: First, the cooling effect is uneven, which easily leads to local overheating or overcooling of the mold, affecting the consistency of product forming. Moreover, the uneven cooling effect will cause inconsistent temperature drops on the inner and outer sides of the lamp housing, making it difficult to demold the lamp housing. Second, it is difficult to maintain. Impurities are easily accumulated inside the water channel, which is inconvenient to clean and may be blocked, affecting the long-term use effect. Therefore, a rapid cooling and shaping device for lamp housings is proposed. Summary of the Invention

[0012] Preferably, the liquid infusion pipe and the liquid outlet pipe are both connected to an external heat exchange device, the liquid infusion pipe is connected to the liquid outlet end of the heat exchange device, and the liquid outlet pipe is connected to the liquid inlet end of the heat exchange device.

[0013] Preferably, the second telescopic rod pushes the extrusion plate to move downward, so that the extrusion plate transports the low-temperature oil inside the oil chamber to the cooling chamber through the connecting port, and the oil pushes the one-way valve to open.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figures 1 to 8 shown, the present invention provides a rapid cooling and shaping device for automobile lamp covers, including a base 1. A pair of first telescopic rods 2 are fixedly connected to the top of the base 1. A mold two 4 is installed inside the base 1. The device further includes: A forming component 3, which is installed inside the base 1 for shaping the lamp cover; An adjustment component 5, which is arranged inside the forming component 3 and is used for replacing the oil liquid inside the forming component 3; A wind cooling component 6, which is arranged inside the mold two 4 for cooling the mold two 4; Among them, the forming component 3 includes a support frame 301 fixedly connected to the first telescopic rod 2. A mold one 302 is fixedly connected to the bottom of the support frame 301. An oil chamber 303 is opened inside the mold one 302; The adjustment component 5 includes a pair of second telescopic rods 501 fixedly connected to the bottom of the support frame 301. An extrusion plate 502 is fixedly connected to the output end of the second telescopic rod 501.

[0020] Adopting the above solution: The extrusion plate 502 is quickly pushed downward by the second telescopic rod 501, so that the extrusion plate 502 quickly extrudes the low-temperature oil liquid inside the oil chamber 303 to be conveyed into the cooling chamber 304 through the communication port 306. At this time, the low-temperature oil liquid will extrude the hot oil liquid to be discharged from the check valve 508. At the same time, the low-temperature oil liquid quickly fills the inside of the cooling chamber 304. At this time, the low-temperature oil liquid quickly absorbs the heat of the hot plastic, so that it is quickly shaped.

[0021] As Figures 2 to 5As shown in the figure, the forming assembly 3 further includes a cooling cavity 304 opened inside the first mold 302. The inside of the cooling cavity 304 is fixedly connected with partition plates 305 at equal intervals. Communication ports 306 are linearly distributed in the middle of the oil cavity 303 and the cooling cavity 304. A model cavity is provided at the bottom of the first mold 302. The cooling cavity 304 matches the shape of the model cavity. The first mold 302 is located above the cooling cavity 304. The first mold 302 is fitted with the second mold 4. Discharge channels are provided on both sides of the cooling cavity 304.

[0022] Adopting the above solution: By setting the forming assembly 3, the first mold 302 is driven by the support frame 301 to move, so that the first mold 302 moves downward to close with the second mold 4, forming a closed mold for injection molding. The oil cavity 303 and the cooling cavity 304 opened inside the first mold 302 are used to store oil. Among them, the cooling cavity 304 stores the oil that has absorbed heat once, and the oil cavity 303 stores the low-temperature oil that has undergone heat exchange. The design of the partition plate 305 enables the inside of the cooling cavity 304 to be divided into multiple cavities, so that the oil inside the cooling cavity 304 can be quickly extruded. The design of the communication port 306 connects the oil cavity 303 with the cooling cavity 304, enabling the oil inside the cooling cavity 304 to be quickly replaced by the oil inside the oil cavity 303.

[0023] As Figures 3 to 7 shown, the output end of the second telescopic rod 501 penetrates the top of the first mold 302 and is movably connected inside the oil cavity 303. The extrusion plate 502 is slidably connected inside the oil cavity 303. The extrusion plate 502 matches the oil cavity 303. An injection port 7 is provided on the side of the first mold 302.

[0024] Adopting the above solution: By setting the adjustment assembly 5, by setting the second telescopic rod 501 and the extrusion plate 502, the second telescopic rod 501 is used to push the extrusion plate 502 to move, so that the extrusion plate 502 extrudes the oil in the oil cavity 303 to quickly enter the cooling cavity 304 through the communication port 306, and the oil inside the cooling cavity 304 is quickly replaced.

[0025] As Figures 2 to 7As shown, the adjustment component 5 further includes a limit frame 503 fixedly connected inside the communication port 306. A one-way valve 504 is arranged below the limit frame 503. An elastic blocking frame 505 is arranged in the middle of the one-way valve 504. One side of the top of the first mold 302 is fixedly connected with a liquid supplement pipe 506. At the same time, a plurality of liquid outlet pipes 507 are fixedly connected to both sides of the first mold 302. The limit frame 503 is distributed at both ends of the hole of the communication port 306. The one-way valve 504 is located in the middle of the limit frame 503, and the one-way valve 504 opens unidirectionally towards the cooling cavity 304. The elastic blocking frame 505 is slidably connected with the limit frame 503 at the top and abuts against the one-way valve 504. A blocking rod is arranged at one end of the elastic blocking frame 505 located below the one-way valve 504. An elastic member is arranged inside the elastic blocking frame 505, and the elastic blocking frame 505 abuts against the limit frame 503 at the bottom of the limit frame 503.

[0026] Adopting the above solution: By setting the limit frame 503, the communication port 306 is sealed by the one-way valve 504 in the middle of the limit frame 503, so that the oil chamber 303 can only convey oil unidirectionally into the cooling cavity 304. When the second telescopic rod 501 pulls the extrusion plate 502 to reset, at this time the one-way valve 504 will close, and at the same time the elastic member inside the elastic blocking frame 505 resets, causing the elastic blocking frame 505 to be pulled upward to squeeze and close the one-way valve 504 and seal the communication port 306.

[0027] As Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, one-way valves 508 are arranged at the ends of the liquid supplement pipe 506 and the liquid outlet pipes 507 communicating with the first mold 302. One end of the liquid supplement pipe 506 is connected to the inside of the oil chamber 303. A liquid supplement groove is opened between the liquid supplement pipe 506 and the oil chamber 303, and this liquid supplement groove extends to the bottom of the oil chamber 303. The liquid outlet pipes 507 are located on both sides of the cooling cavity 304 and are connected to the cooling cavity 304. The liquid supplement pipe 506 and the liquid outlet pipes 507 are both connected to an external heat exchange device. The liquid supplement pipe 506 is connected to the liquid outlet end of the heat exchange device, and the liquid outlet pipes 507 are connected to the liquid inlet end of the heat exchange device.

[0028] Adopting the above solution: While the extrusion plate 502 resets, the inside of the oil chamber 303 will suck the low-temperature oil that has been cooled by heat exchange from the liquid supplement pipe 506 into the oil chamber 303. The liquid supplement groove opened between the liquid supplement pipe 506 and the oil chamber 303 can ensure that when the extrusion plate 502 resets, oil is pumped from the liquid supplement pipe 506, so that the oil in the oil chamber 303 can be replenished in time; The arrangement of the liquid outlet pipe 507 facilitates the discharge of the oil in the cooling chamber 304. Meanwhile, the arrangement of the one-way valve 508 enables the liquid supply pipe 506 to only input oil into the oil chamber 303 in one direction, and the liquid outlet pipe 507 can only transport the oil in the cooling chamber 304 outwards in one direction, thereby ensuring the one-way flow of the oil in the oil chamber 303 and the cooling chamber 304, preventing the oil in the cooling chamber 304 from flowing back after absorbing heat and affecting the cooling effect next time. At the same time, the cooling chamber 304 is divided into multiple compartments by the partition plate 305 inside, which facilitates the rapid discharge of the oil in the cooling chamber 304.

[0029] As Figures 2 to 8 shown, the second telescopic rod 501 pushes the extrusion plate 502 to move downward, so that the extrusion plate 502 transports the low-temperature oil in the oil chamber 303 to the inside of the cooling chamber 304 through the communication port 306. The oil pushes the one-way valve flap 504 to open, and at this time, the one-way valve flap 504 will push the elastic blocking frame 505 to move downward. At the same time, the low-temperature oil in the oil chamber 303 will push the oil in the cooling chamber 304 that has absorbed heat to be pushed out from the liquid outlet pipe 507.

[0030] Adopting the above solution: when the second telescopic rod 501 pushes the extrusion plate 502 to move downward, at this time, the extrusion plate 502 transports the low-temperature oil in the oil chamber 303 to the inside of the cooling chamber 304 through the communication port 306. When the oil moves, it will push the one-way valve flap 504 to open. At this time, the one-way valve flap 504 will push the elastic blocking frame 505 to move downward. At the same time, the low-temperature oil in the oil chamber 303 will push the oil in the cooling chamber 304 that has absorbed heat to be pushed out from the liquid outlet pipe 507, quickly completing the replacement of the oil in the cooling chamber 304.

[0031] As Figure 3 and Figure 8 shown, the wind cooling component 6 includes a pair of heat conduction plates 601 fixedly connected inside the mold two 4. The heat conduction plates 601 are fixedly connected with heat dissipation fins 602 inside. The bottom of the mold two 4 is fixedly connected with a vortex fan 603. The fins of the heat dissipation fins 602 are vertically distributed with the air outlet of the vortex fan 603.

[0032] Adopting the above solution: by setting the wind cooling component 6, the heat at the mold two 4 is conducted to the heat dissipation fins 602 by the heat conduction plates 601, and then the vortex fan 603 blows air on the heat dissipation fins 602 to cool down the heat dissipation fins 602.

[0033] Working principle and usage process of the present invention: During production, the first telescopic rod 2 pushes the support frame 301 downward, causing the support frame 301 to drive the first mold 302 downward, so that the first mold 302 is closed and sealed with the second mold 4. Then, injection molding is carried out through the injection port 7 between the second mold 4 and the first mold 302. When injection molding is in progress, the oil liquid inside the cooling cavity 304 will first absorb part of the heat of the hot plastic. At the same time, the heat conducting plate 601 inside the second mold 4 synchronously absorbs part of the heat. After injection molding is completed, the second telescopic rod 501 quickly pushes the extrusion plate 502 downward, causing the extrusion plate 502 to quickly extrude the low-temperature oil liquid inside the oil liquid cavity 303 to be transported into the cooling cavity 304 through the communication port 306. At this time, the low-temperature oil liquid will squeeze the hot oil liquid to be discharged from the one-way valve 508. At the same time, the low-temperature oil liquid quickly fills the inside of the cooling cavity 304. At this time, the low-temperature oil liquid quickly absorbs the heat of the hot plastic, causing it to quickly take shape; While the oil liquid inside the cooling cavity 304 is being replaced, the eddy current fan 603 located at the bottom will start to blow air on the heat dissipation fins 602, causing the heat dissipation fins 602 to cool down the heat conducted from the heat conducting plate 601 by the blowing of the eddy current fan 603; Through different heat conduction methods on both sides, the outside of the lampshade is quickly cooled by heat absorption, making the outside of the lampshade quickly cooled. At the same time, the inside of the lampshade absorbs heat from the second mold 4 through the heat conducting plate 601, resulting in different cooling speeds for the inside and outside of the lampshade. The outside of the lampshade is stabilized first, and the inside is stabilized later, causing the lampshade body to be separated from the first mold 302, facilitating the removal of the lampshade.
