[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0022] As Figures 1 to 4As shown in the figure, this embodiment discloses a pressing die for a composite paper tray, which includes a pressing die body 100 and an ejection assembly 300. The pressing die body 100 includes an upper die 112 and a lower die. The bottom surface of the upper die 112 is provided with a plurality of cavities (two cavities are provided in this embodiment, and it is not limited to this in other embodiments) that cooperate with the cores on the lower die. The ejection assembly 300 is installed inside the upper die 112. An air injection port 310 is provided on the surface of the upper die 112. Inside the upper die 112, a cavity body 311 is provided above each cavity. A push rod 312 is slidably arranged in each cavity body 311. The push rod 312 is generally T-shaped. The push rod 312 includes a rod head, a rod body, and an embedded push head 314. A threaded spring 313 is sleeved on the rod body. One end of the threaded spring 313 abuts against the rod head, and the other end abuts against the bottom surface of the cavity body 311. A through hole communicating with the cavity is provided on the bottom surface of the cavity body 311. The part of the cavity body 311 above the rod head is communicated with the air injection port 310 through an air passage. By inputting gas into the air injection port 310, the gas pushes the push rod 312 to move downward so that the embedded push head 314 extends into the cavity to push the paper tray to demold.

[0023] One end of the air injection port 310 is externally connected with a nano hose, and a blower is connected to one side of the hose. After the upper die 112 and the lower die are pressed together, the paper tray will get stuck in the groove of the upper die 112. At this time, the gas enters through the air injection port 310. The gas pressure pushes the push rod 312 to compress the threaded spring 313, so that the embedded push head 314 pushes the paper tray downward to demold. When the gas stops entering, the threaded spring 313 will recover, so that the embedded push head 314 resets, and repeated ejection actions can be performed to help the paper tray to demold and blank automatically.

[0024] The pressing die body 100 further includes an upper top plate 110 and a lower base plate 111. The top plate and the lower base plate 111 are parallel and opposite to each other up and down. A lower die and a plurality of guide columns 113 (four guide columns are provided in this embodiment, at the four ends of the lower base plate respectively, and the lower die is installed in the middle of the top surface of the lower base plate) are installed on the lower base plate 111. The guide columns 113 pass through the upper top plate 110, and the upper die 112 is installed on the bottom surface of the upper top plate 110. The guide columns guide the up and down movement of the upper top plate 110.

[0025] Under normal conditions, the embedded push head 314 and the top surface of the cavity of the upper die 112 are kept horizontal, and the embedded push head 314 is trapezoidal frustum-shaped with a narrow upper part and a wide lower part. The shape of the embedded push head 314 with a narrow upper part and a wide lower part will enable the embedded push head 314 to be effectively limited after resetting, avoiding uneven inner walls caused by excessive contraction.

[0026] On one side of the lower substrate 111, a pushing component 200 is provided. The pushing component 200 includes a receiving tray 210, an electric push rod 215, a driving motor 211, a fixed bracket, and a moving bracket. The fixed bracket includes a fixed rod and two spaced-apart auxiliary rods 214 vertically connected to one side of the fixed rod. The moving bracket includes a sliding plate 213 and two columns 212 connected to the sliding plate 213. The two auxiliary rods 214 pass through the sliding plate 213, and the lower substrate 111 is located along the axial direction of the two auxiliary rods 214. The electric push rod 215 is installed on the fixed rod and its driving end is connected to the sliding plate 213. The electric push rod 215 drives the sliding plate 213 to move along the two auxiliary rods 214. The upper ends of the two columns 212 are connected by a rotating rod. One end of the rotating rod is connected to the output shaft of the driving motor 211, and the bottom of the receiving tray 210 is fixedly connected to the rotating rod. The driving motor 211 drives the receiving tray 210 to rotate. Preferably, the side profile of the receiving tray 210 is concave, and the receiving tray 210 is made of aluminum alloy. When the electric push rod 215 is started, it drives the sliding plate 213 to slide horizontally on the auxiliary rod 214, pushes the upper receiving tray 210 below the upper mold 112 to catch the paper tray after demoulding, and then takes it out for blanking. By starting the driving motor 211 to drive the receiving tray 210 to rotate and tilt, the paper tray is automatically discharged downward into the collection box.

[0027] In summary, when the pressing mold of the composite paper tray disclosed in the embodiment of the present application is in use, after the upper mold 112 and the lower mold are pressed, the paper tray will be stuck in the groove of the upper mold 112. At this time, gas enters through the air injection port 310, and the push rod 312 is pushed by the gas pressure to compress the threaded spring 313, so that the embedded push head 314 pushes the paper tray downward for demoulding. When the gas stops entering, the threaded spring 313 will recover, so that the embedded push head 314 resets. When the electric push rod 215 is started, it drives the sliding plate 213 to slide horizontally on the auxiliary rod 214, pushes the upper receiving tray 210 below the upper mold 112 to catch the paper tray after demoulding, and then takes it out for blanking. By starting the driving motor 211 to drive the receiving tray 210 to rotate and tilt, the paper tray is automatically discharged downward into the collection box.
