[0011] By adopting the above technical solution, water is transported through a spiral pipe, extending the water transport time and thus improving the heat dissipation effect on the lower mold.

[0012] Furthermore, the telescopic end of the cylinder extends into the interior of the countersunk hole, the lifting member and the countersunk hole are engaged and connected, the outer end face of the lifting member is flush with the bottom end face inside the lower mold, and the lifting member and the countersunk hole are tightly fitted together.

[0013] By adopting the above technical solution, through countersunk holes and lifting components, rapid demolding can be performed after the product is formed, thereby improving production efficiency.

[0014] Furthermore, the telescopic end of the hydraulic cylinder is fixedly connected to the carrier plate, and the carrier plate and the support rod are slidably connected.

[0017] It employs a cooling chamber, spiral pipe, cylinder, and lifting component. The cooling chamber and spiral pipe are added inside the mold, and water can be transported through the spiral pipe to cool the lower mold. Water is continuously supplied into the spiral pipe for cooling. At the same time, the lifting structure is added inside the lower mold to improve the efficiency of product demolding, resulting in efficient cooling and rapid demolding. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1-7 An automatic demolding device for paper tableware includes a workbench 1, a cooling chamber 2 inside the workbench 1, a lower mold 3 fixedly connected to the center inside the workbench 1, a heat-conducting component 4 fixedly connected to the outer side of the lower mold 3, a spiral pipe 5 provided on the outer side of the heat-conducting component 4, a countersunk hole 6 and a mounting groove 7 inside the lower mold 3, a cylinder 8 installed inside the mounting groove 7, a lifting component 9 fixedly connected to the telescopic end of the cylinder 8, a support rod 10 fixedly connected to the outer side of the workbench 1, and a carrier plate 11 fixedly connected to the outer side of the support rod 10. The upper mold 12 is fixedly connected inside the workbench 11, and the hydraulic cylinder 13 is fixedly connected to the outside of the carrier plate 11. A cooling chamber 2 is added to the outside of the workbench 1 and the lower mold 3. A spiral pipe 5 is added inside the cooling chamber 2 to cool the lower mold 3. At the same time, a lifting structure is added inside the lower mold 3 so that the product can be ejected from the mold for easy demolding. Water is transported through the spiral pipe 5 to extend the water transport time and improve the heat dissipation effect on the lower mold 3.

[0028] like Figure 1-7 As shown, the inner side of the heat-conducting component 4 is in close contact with the outer side of the lower mold 3. The spiral pipe 5 is spirally wound around the outer side of the heat-conducting component 4 and is in contact with the outer side of the heat-conducting component 4. The two ends of the outer side of the spiral pipe 5 are respectively fixedly connected to the inlet pipe 51 and the outlet pipe 52. The telescopic end of the cylinder 8 extends into the interior of the countersunk hole 6. The lifting component 9 and the countersunk hole 6 are engaged. The outer end face of the lifting component 9 is flush with the bottom end face inside the lower mold 3. The lifting component 9 and the countersunk hole 6 are tightly fitted together. The telescopic end of the hydraulic cylinder 13 is fixedly connected to the carrier plate 11. The carrier plate 11 and the support rod 10 are slidably connected.

[0029] The implementation principle of this embodiment is as follows: water is transported into the spiral pipe 5 through the inlet pipe 51 and then out through the outlet pipe 52. The water cools the lower mold 3. At the same time, the structure of the spiral pipe 5 can increase the time that the water is transported inside the pipe, remove more heat, and improve the heat dissipation and cooling effect. Meanwhile, the cylinder 8 at the bottom controls the lifting part 9 to move and push out the mold, making it easier to demold and making the mold for paper tableware more convenient to use.
