Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5As shown, a rapid cooling injection mold for a front seat back panel includes a base 100. A support column 101 is fixedly connected to the upper end of the base 100. A fixed mold 200 is fixedly connected to the upper end of the support column 101. Four limiting columns 201 are fixedly connected to the upper end of the fixed mold 200. A moving mold 300 is slidably connected to the outer end of each limiting column 201. A feed pipe 301 is connected to the top of the moving mold 300. A front seat back panel forming cavity 202 is provided at the upper end of the fixed mold 200. The fixed mold 200 contains a surrounding cavity for the front seat back panel. The molding cavity 202 has a cooling cavity 203, which is equipped with a cooling mechanism. The lower end of the fixed mold 200 is equipped with an ejector for ejecting the model. The upper end of the base 100 is equipped with a transmission component for driving the ejector. The moving mold 300 moves downward along the limiting post 201 and closes with the fixed mold 200. The cooling mechanism in the cooling cavity 203 accelerates the cooling of the front seat back panel model. The moving mold 300 is opened, and the transmission component drives the ejector to eject the front seat back panel model in the molding cavity 202.

[0026] In this embodiment, as Figure 1 and Figure 4 As shown, the cooling mechanism includes a spiral cooling pipe 401 located in the cooling chamber 203. The inlet of the spiral cooling pipe 401 is fixedly connected to the outlet of a water pump 402. The inlet of the water pump 402 is fixedly connected to the outlet of a water tank 403. The inlet of the water tank 403 is fixedly connected to the outlet of a heat exchanger 404. The inlet of the heat exchanger 404 is connected to the outlet of the spiral cooling pipe 401. An installation groove 405 is provided on the inner wall of the cooling chamber 203, and a fan 4 is fixedly connected in the installation groove 405. 06. A vent 407 is provided on the side of the cooling chamber 203 away from the fan 406. The water pump 402 draws the cooling water in the water tank 403 into the spiral cooling pipe 401 to exchange heat with the molding chamber 202 for cooling. The cooling water that has absorbed heat enters the heat exchanger 404 for further cooling and then returns to the water tank 403 to circulate and cool the molding chamber 202. The fan 406 increases the flow of gas in the cooling chamber 203, allowing heat to dissipate more quickly and accelerating the cooling speed. The fan 406 applies the cold air to the outer surface of the molding chamber, making the cooling more uniform.

[0027] In one embodiment, such as Figure 2As shown, the ejection component includes an ejection plate 501. Four sliding pillars 502 are fixedly connected to the upper end of the ejection plate 501. The sliding pillars 502 are slidably connected to the fixed mold 200. A spring 503 is sleeved on the sliding pillars 502. One end of the spring 503 is connected to the lower end of the fixed mold 200, and the other end of the spring 503 is connected to the upper end of the ejection plate 501. An ejection pin 504 is fixedly connected to the upper end of the ejection plate 501, and an ejector pin 505 is fixedly connected to the lower end of the ejection plate 501. When the ejection plate 501 moves upward, it drives the sliding pillars 502 upward and compresses the spring 503. The ejection pin 504 at the upper end of the ejection plate 501 ejects the front seat back panel model in the molding cavity 202. After ejection, the spring 503 pushes the ejection plate 501 to reset.

[0028] In one embodiment, such as Figure 3 and Figure 5 As shown, the transmission component includes a push block 601, which is fixedly connected to the upper end of a sliding plate 602. The sliding plate 602 is slidably connected to a transmission bracket 603, which is fixedly connected to the upper end of a base 100. One end of the sliding plate 602 extends out of the transmission bracket 603 and is fixedly connected to a gear plate 604. A gear plate 605 is fixedly connected to the upper end of the base 100. A gear 606 meshes between the gear plate 604 and the gear plate 605. One end of a connecting rod 607 is rotatably connected to the gear 606. The other end of the connecting rod 607 is rotatably connected to one end of a connecting rod 608. The other end of the connecting rod 608 is connected to a motor 609. The output shaft is connected, the motor 609 is fixedly connected to the transmission bracket 603, the push block 601 is connected to the top column 505, the motor 609 rotates, driving the second connecting rod 608 to rotate, the second connecting rod 608 drives the first connecting rod 607 to push the gear 606. Since the second gear plate 605 is fixed, the gear 606 meshes with the second gear plate 605, so that the gear 606 rotates along the second gear plate 605. The gear 606 also meshes with the first gear plate 604, driving the first gear plate 604 and the sliding plate 602 to slide along the transmission bracket 603. The push block 601 on the sliding plate 602 lifts and lowers the top column 505, achieving the effect of pushing out the front seat back panel model and resetting the push plate 501 after pushing out.

[0029] In one embodiment, such as Figure 3 As shown, the upper end of the fixed mold 200 is provided with a sealing ring 700 to increase the sealing between the moving mold 300 and the fixed mold 200 and prevent leakage.

[0030] In one embodiment, such as Figure 4As shown, a filter plate 800 is fixedly connected in the mounting groove 405. The filter plate 800 is located on the side of the fan 406 away from the spiral cooling pipe 401. The filter plate 800 filters dust in the air and prevents dust from adsorbing in the spiral cooling pipe 401 and the cooling chamber 203, thus affecting the cooling effect.

[0031] In one embodiment, such as Figure 2 As shown, the ejector pins 504 are four evenly arranged in the molding cavity 202, so that when the front seat back panel model is ejected, the front seat back panel model is subjected to uniform force, which is less likely to cause deformation and damage to the front seat back panel model.

[0032] In one embodiment, such as Figure 2 As shown, the toothed plate 604 and the toothed plate 605 are parallel to each other to ensure the normal operation of the device.

[0033] The above embodiment discloses a rapid cooling injection mold for a front seat back panel. The moving mold 300 moves downwards along the limiting post 201, and the moving mold 300 and fixed mold 200 close. Molding material is injected into the molding cavity 202 from the feed pipe 301. A water pump 402 draws cooling water from the water tank 403 into the spiral cooling pipe 401, where it exchanges heat with the molding cavity 202 for cooling. The cooled water, having absorbed heat, enters the heat exchanger 404 for further cooling and then returns to the water tank 403 to circulate and cool the molding cavity 202. A fan 406 increases the airflow in the cooling cavity 203, allowing heat to dissipate more quickly and accelerating the cooling process. The fan 406 applies cool air to the outer surface of the molding cavity, resulting in more uniform cooling and rapid cooling of the front seat back panel model. After the front seat back panel model has cooled, the motor... Rotation of 609 drives the second connecting rod 608 to rotate. The second connecting rod 608 drives the first connecting rod 607 to push the gear 606. Since the second gear plate 605 is fixed, the gear 606 meshes with the second gear plate 605, causing the gear 606 to rotate along the second gear plate 605. The gear 606 also meshes with the first gear plate 604, causing the first gear plate 604 and the sliding plate 602 to slide along the transmission bracket 603. The push block 601 on the sliding plate 602 lifts and lowers the top column 505. The ejector plate 501 moves upward, driving the sliding column 502 upward and compressing the first spring 503. The ejector pin 504 at the upper end of the ejector plate 501 ejects the front seat back panel model in the molding cavity 202. After ejection, the first spring 503 pushes the ejector plate 501 to reset, facilitating the ejection of the front seat back panel model and improving work efficiency.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
