[0024] Example 1: Please refer to Figure 1 - Figure 6 A plastic tableware molding and demoulding device comprises a bottom mold 1, a lower mold groove 2 for molding plastic tableware is provided inside the bottom mold 1, a threaded groove 7 is provided inside the bottom mold 1, and the wind direction is changed by the threaded groove 7, thereby helping the plastic tableware molded inside the lower mold groove 2 to be demoulded, a top block 3 is slidably connected to the top of the bottom mold 1, an upper mold convex block 4 for molding plastic tableware is provided inside the top block 3, an adding structure 5 for spraying an additive is provided on the top of the upper mold convex block 4, and a cover body 6 for storing gas is provided on the outer wall of the top block 3;

[0025] The cover body 6 includes a connecting hose 601, which is fixedly connected to the outer wall of the bottom mold 1. A circular groove 602 for collecting gas is opened inside the bottom mold 1, and the gas enters the threaded groove 7 more evenly through the circular groove 602, and flows up and down to help the plastic tableware to be demoulded.

[0026] See also Figure 1 - Figure 2 A cylinder 101 for pushing the top block 3 upward is fixedly installed inside the bottom mold 1, and the top of the cylinder 101 is fixedly connected to the bottom of the top block 3. A support rod 102 for supporting the bottom of the cover body 6 is fixedly connected to the bottom of the cover body 6. When the top block 3 moves down to the top of the lower bottom mold 1 through the support rod 102, the cover body 6 is lifted up, so that a certain amount of gas is stored inside the cover body 6.

[0027] See also Figure 1 - Figure 2 The adding structure 5 includes a material receiving tray 501, the bottom of the material receiving tray 501 is fixedly connected to the inside of the top block 3, and the top of the material receiving tray 501 is fixedly connected with a connecting hose 2 502, which is fixedly connected to the outer wall of the cover body 6, and the outer wall of the connecting hose 2 502 is fixedly connected to the inner cavity of the top block 3. A circular groove 503 is opened inside the top block 3, and an arc-shaped annular groove 504 is opened at the bottom of the circular groove 503. When the top block 3 rises to squeeze the inside of the cover body 6, the gas inside the cover body 6 can enter the circular groove 503 through the connecting hose 2 502, and the gas blows up the gas on the top of the material receiving tray 501, and enters the lower mold groove 2 through the arc-shaped annular groove 504, the top of the plastic tableware, thereby improving the efficiency and safety of the device and avoiding the need for manual powdering and burns caused by contact with the device.

[0028] See also Figure 5 - Figure 6 A gas pipeline 807 is fixedly connected inside the cover body 6, and a turntable 8 is rotatably connected to the bottom of the gas pipeline 807. Two groups of cap bodies 803 for driving the turntable 8 to rotate are fixedly connected to the outer wall of the turntable 8. Multiple groups of cap bodies 804 are fixedly connected to the outer wall of the turntable 8. A stop block 805 for stopping the cap body 803 is fixedly installed on the top of the cap body 804. The height of the cap body 804 is lower than that of the cap body 803. Therefore, when the cap body 803 and the cap body 804 drive the turntable 8 to rotate, when the stop block 805 contacts the cap body 803, the stop block 805 can stop the turntable 8 through the cap body 803.

[0029] See also Figure 5 - Figure 6 A top rod 801 is fixedly connected to the bottom of the turntable 8, and the bottom of the top rod 801 is rotatably connected to the flap 802. Specifically, a connecting shaft 806 is fixedly connected inside the flap 802, and both ends of the connecting shaft 806 are rotatably connected to the inside of the cover body 6 through bearings.

[0030] The working principle of the utility model is:

[0031] First, the cylinder 101 is driven to move the top block 3 upward, and then the plastic mold mass is placed in the lower mold groove 2, so that the heat generated inside the bottom mold 1 melts the plastic mass, and the cylinder 101 is driven to make the top block 3 drive the upper mold protrusion 4 downward to extrude the plastic mold mass. After the plastic tableware is formed, when it is necessary to sprinkle an additive to increase the smoothness on the surface of the plastic tableware, the cylinder 101 can be driven again to push the cap body 803 to flip during the process of the top block 3 moving upward. Because the top rod 801 can push the top end of the flap 802 The flap 802 is turned toward the end of the second connecting hose 502, so that the compressed gas inside the cover body 6 flows toward the end of the second connecting hose 502, and the gas enters the circular groove 503 through the second connecting hose 502, and blows the additive placed on the top of the material tray 501, so that the additive is sprinkled into the top of the formed tableware through the arc-shaped annular groove 504, and drives the cylinder 101 again, so that the top block 3 drives the upper mold protrusion 4 to squeeze the tableware again. In the process of the top block 3 moving downward, the cover body 6 is moved by the lower mold 10 The limit of the groove 2 stays at a certain height. Therefore, when the space between the cover body 6 and the top block 3 is squeezed, the gas inside the cover body 6 enters the gas supply pipe 807, and in the process of continuous gas supply, the gas inside the gas supply pipe 807 drives the top rod 801 to rotate around the central axis of the turntable 8 through the cap body 1 803 and the cap body 2 804. During the gradual rotation, the air flow pressure gradually decreases, causing the cap body 1 803 to contact the stop block 805. The stop block 805 limits the cap body 1 803, thereby stopping the top rod 801, causing the top rod 801 to stay in the opposite position, so that the cylinder 101 pushes the top block 3 to rise again. When the tableware needs to be taken out, the top block 3 rises to squeeze the air inside the cover body 6 again. At the same time, due to the change in the position of the top rod 801, the tilting direction of the flap 802 changes, causing the gas to enter the circular groove 602 through the connecting hose 1 601, and continuously move upward through the threaded groove 7 to blow out the already formed inside the bottom mold 1, thereby facilitating the staff to take out the bowl body.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
