[0017] Refer to Figures 1 to 4 As shown in the figure, the utility model provides a food packaging box forming mold device, including: a base 1 and a fixed mold 3. The upper surface of the base 1 is fixedly connected with a fixed frame 7 and a fixed mold 3 respectively. Installation grooves are opened inside both the base 1 and the fixed mold 3. An electric rod 5 is fixedly connected inside the installation groove, and the telescopic rod of the electric rod 5 is fixedly connected with a push plate 4. The push plate 4 is slidably connected in the mold cavity of the fixed mold 3. The top of the fixed frame 7 is fixedly connected with a servo electric cylinder 16, and the telescopic rod of the servo electric cylinder 16 is fixedly connected with a moving plate 15. At the same time, a flow splitting groove 2 is opened inside the base 1, and an air pump 8 is fixedly connected to the side of the base 1. The air pump 8 is communicated with the flow splitting groove 2 through an air pipe. Side air grooves 17 and end air grooves 6 are symmetrically opened on both sides and at both ends of the fixed mold 3 respectively. The lower ends of the side air grooves 17 and the end air grooves 6 are both communicated with the flow splitting groove 2, and the upper end of the end air groove 6 is communicated with a top air groove 13 opened inside the moving plate 15. The lower surface of the moving plate 15 is fixedly connected with a movable mold 9, the outer side surface of the movable mold 9 is fixedly connected with a heat conducting plate 10, injection molding pipes 11 are fixedly connected inside both the movable mold 9 and the moving plate 15. At the same time, a heat dissipation rod 14 is correspondingly connected at a position on the upper surface of the heat conducting plate 10 opposite to the top air groove 13, and the upper end of the heat dissipation rod 14 is fixedly connected inside the top air groove 13.

[0018] In this embodiment, after injecting the injection molding raw material into the mold cavity of the fixed mold 3 through the injection molding pipe 11, the switch of the air pump 8 is turned on. The air pump 8 injects gas into the flow splitting groove 2 through the air pipe. Part of the gas will flow into the end air groove 6, and the other part of the gas will flow to the outside through the side air groove 17. During the flow of the gas in the end air groove 6 and the side air groove 17, the outer side surface of the food packaging box can be rapidly cooled by heat dissipation. The gas in the end air groove 6 will flow to the outside through the communicated top air groove 13. During the flow of the gas in the top air groove 13, the air flow can perform corresponding air-cooled heat dissipation on the heat dissipation rod 14, so that the heat conducting plate 10 can rapidly transfer the heat inside the food packaging box to the heat dissipation rod 14, thereby improving the overall heat dissipation and cooling efficiency of the food packaging box, and further effectively reducing the waiting time of workers for the food packaging box to cool and improving the demolding efficiency of the food packaging box. After the food packaging box is cooled, the switch of the air pump 8 is turned off, and the reset switch of the servo electric cylinder 16 is turned on. The telescopic rod of the servo electric cylinder 16 drives the moving plate 15, the movable mold 9 and the heat conducting plate 10 to reset synchronously. Then the switch of the electric rod 5 is turned on, and the telescopic rod of the electric rod 5 pushes the food packaging box to move upward through the push plate 4, thereby completing the detachment process of the food packaging box and facilitating the injection molding operation of the next food packaging box.

At the same time, the installation groove formed in the base 1 is located inside the flow-dividing groove 2, and the mold cavity sizes of the push plate 4 and the fixed mold 3 are adapted to each other.

[0020] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the formation of the flow-dividing groove 2 enables a plurality of groups of end air grooves 6 and side air grooves 17 formed in the side wall of the fixed mold 3 to inject gas synchronously, facilitating the improvement of the cooling effect of the fixed mold 3 on the food packaging box.

The heat-insulating layer is fixedly connected to the outer side surface of the heat-conducting layer, and both the end air grooves 6 and the side air grooves 17 are formed on the outer side surface of the heat-conducting layer. At the same time, the heat-insulating layer has a square structure.

[0024] In this embodiment, as shown in Figure 1 and Figure 3 , the layered structure of the fixed mold 3 can not only ensure that the raw materials can maintain an appropriate temperature during injection molding, improving the quality of the injection molding of the food packaging box, but also improve the heat dissipation and cooling efficiency of the food packaging box after the injection molding of the food packaging box.

[0025] As a preferred embodiment, the moving plate 15 has a square structure, the size of the moving plate 15 is adapted to the upper surface of the fixed mold 3, and a plurality of groups of top air grooves 13 are formed in the moving plate 15 in parallel and at equal intervals. The top air grooves 13 have an F-shaped structure. At the same time, the number and positions of the bottom openings of the end air grooves 6 and the top air grooves 13 correspond one by one.

[0026] In this embodiment, as shown in Figure 1 and Figure 2 , the top air grooves 13 formed in the moving plate 15 enable the inside of the moving plate 15 to perform corresponding auxiliary heat dissipation when the air flows, and then can assist in improving the heat dissipation speed of the food packaging box.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 4 , the gasket 12 can be made of soft rubber material, which can then assist in enhancing the sealing performance of the contact surface between the moving plate 15 and the fixed mold 3. At the same time, the gasket 12 is fixedly connected to the edge of the lower surface of the moving plate 15 through a groove, which can effectively reduce the probability of the food packaging box contacting the gasket 12 during injection molding.
