[0019] Example

[0020] like Figure 1-3 As shown, a fast-discharging plastic mold comprises a fixing frame 1 and a controller 2, wherein one end of the fixing frame 1 is fixedly connected to the controller 2, and one end of the fixing frame 1 is fixedly connected to a first electric telescopic rod 3, and the bottom end of the first electric telescopic rod 3 is fixedly connected to an upper mold body 4, and the upper mold body 4 can be moved in a vertical direction by the first electric telescopic rod 3, so that the upper mold body 4 can be automatically separated from the lower mold body 5, and the two ends of the fixing frame 1 are rotatably connected to a first ventilation pipe 6 and a second ventilation pipe 7, and one end of the first ventilation pipe 6 is connected to the lower mold body 5 on the outside, The lower mold body 5 is connected to the second ventilation pipe 7, and the first ventilation pipe 6 and the second ventilation pipe 7 are both fixedly connected to the lower mold body 5. A cavity 9 is opened on the inner side of the lower mold body 5, and the first ventilation pipe 6 and the second ventilation pipe 7 are both connected to the cavity 9. An ejection mechanism is arranged on the inner side of the bottom end of the lower mold body 5, and a rotating mechanism is arranged at one end of the first ventilation pipe 6. Low-temperature gas can be introduced into the inner side of the cavity 9 through the first ventilation pipe 6, and the contact part between the lower mold body 5 and the plastic product is cooled by the low-temperature gas, thereby facilitating the removal of the plastic product from the inner side of the lower mold body 5.

[0021] As a further improvement of the utility model, Figure 1 , Figure 2 and Figure 3As shown, one end of the first ventilation pipe 6 is connected to an air supply pipe 14, and the air supply pipe 14 is connected to an external low-temperature gas source. The other end of the second ventilation pipe 7 is connected to an electromagnetic valve 8. The air supply pipe 14 is made of a metal hose, thereby ensuring that the air supply pipe 14 does not affect the rotation of the first ventilation pipe 6 and the lower mold body 5. At the same time, the opening and closing of the second ventilation pipe 7 can be controlled by the electromagnetic valve 8, so as to facilitate the discharge of high-temperature gas inside the cavity 9 and allow low-temperature gas to enter the inner side of the cavity 9.

[0022] As a further improvement of the utility model, Figure 2 As shown, the ejection mechanism includes an ejector cylinder 15 slidably connected to the lower mold body 5, an air groove 16 is opened on the inner side of the ejector cylinder 15, and connecting blocks 18 are fixedly connected to both ends of the ejector cylinder 15. As the gas pressure inside the cavity 9 gradually increases, the ejector cylinder 15 will move. Under the action of the ejector cylinder 15, the plastic product can be ejected from the inner side of the lower mold body 5 for a distance. No manual operation is required, which is convenient for staff to use and improves overall work efficiency.

[0023] As a further improvement of the utility model, Figure 2 As shown, one end of the connecting block 18 is fixedly connected to a spring 17, and the spring 17 is fixedly connected to the lower mold body 5. The spring 17 applies a downward pressure to the top cylinder 15 through the connecting block 18 to ensure that the thrust of the low-temperature gas inside the top cylinder 15 to the top cylinder 15 is greater than the downward pressure applied by the spring 17 to the top cylinder 15 through the connecting block 18. Only then will the top cylinder 15 eject the plastic product from the lower mold body 5, so that the lower mold body 5 and the plastic mass have sufficient cooling time.

[0024] As a further improvement of the utility model, Figure 1 and Figure 3 As shown, the rotating mechanism includes a second electric telescopic rod 13 fixedly connected to the fixed frame 1, one end of the second electric telescopic rod 13 is fixedly connected to a rack 11, the outer side of the rack 11 is slidably connected to a limit frame 12, and the limit frame 12 is fixedly connected to the fixed frame 1, one end of the rack 11 is meshed with a gear 10, and the gear 10 is fixedly connected to the first ventilation pipe 6. With the mutual cooperation of the gear 10 and the rack 11, the lower mold body 5 can be flipped 180 degrees, so that the plastic product can be moved out from the inner side of the lower mold body 5 with the action of the top cylinder 15, without the need for manual removal, and the operation is simple, thereby improving work efficiency.

[0025] Working process: when a plastic product, such as a plastic barrel, is manufactured by using the upper mold body 4 and the lower mold body 5, after the plastic barrel is manufactured, the upper mold body 4 is removed from the surface of the lower mold body 5 by the first electric telescopic rod 3, and the solenoid valve 8 is opened at the same time, so that the external low-temperature gas source rushes into the cavity 9 inside the lower mold body 5 through the gas supply pipe 14 and the first ventilation pipe 6. At the same time, the low-temperature gas will also cause the high-temperature gas in the cavity 9 to be discharged through the second ventilation pipe 7 and the solenoid valve 8, and the lower mold body 5 and the plastic barrel are cooled by the low-temperature gas, and then the solenoid valve 8 is closed, and the cooling continues through The gas supply pipe 14 and the first ventilation pipe 6 introduce low-temperature gas into the cavity 9, so that the low-temperature gas enters the inner side of the gas groove 16 and gradually pushes the ejector 15. Under the action of the ejector 15, the plastic product can be ejected from the inner side of the lower mold body 5 for a distance. At the same time, the second electric telescopic rod 13 will also rotate clockwise with the gear 10 through the rack 11, so that the gear 10 will turn downward 180 degrees with the lower mold body 5 through the first ventilation pipe 6, so that the plastic barrel will automatically fall from the inner side of the lower mold body 5, without manual operation, which is convenient for the staff to use and improves the overall work efficiency.
