DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figure 1 - Figure 2 , the present utility model provides an umbrella manufacturing device for hot pressing and forming a plastic umbrella surface, including: a base 1, columns 3, a cross beam 4, and an umbrella surface hot pressing block 6. The base 1 is of a square structure, an installation groove is formed on the upper surface of the base 1, the installation groove is of a regular hexagon structure, a positioning plate 2 is fixedly connected in the installation groove, the positioning plate 2 is of a regular hexagonal pyramid structure, a through hole is formed at the conical tip of the positioning plate 2, the through hole is of a cylindrical structure, the regular hexagonal pyramid structure can adapt to the shape of the umbrella surface, and the bottom of the positioning plate 2 is hollow to place the umbrella cover of the umbrella.

[0017] The interior of the base 1 has a hollow structure. The base 1 and the positioning plate 2 form a cavity. At the corners of the upper surface of the base 1, the columns 3 are symmetrically connected. The columns 3 are all in the shape of a cuboid. The upper surface of the columns 3 is fixedly connected to the crossbeam 4. The crossbeam 4 is in the shape of a square. A servo electric cylinder 5 is fixedly connected to the crossbeam 4.

[0018] The telescopic rod of the servo electric cylinder 5 is fixedly connected to the umbrella surface hot pressing block 6. The umbrella surface hot pressing block 6 is in the shape of a regular hexagonal pyramid. The umbrella surface hot pressing block 6 can move up and down through the telescopic rod.

[0019] A fixed plate 9 is fixedly installed in the cavity. 18 vacuum generators 7 are fixed on the fixed plate 9. 18 suction holes 8 are provided on the upper surface of the positioning plate 2. The vacuum generators 7 are connected to the suction holes 8 through suction hoses 73.

[0020] The vacuum generator 7 includes: a vacuum generator body 71, an adsorption tube 72, and a suction hose 73. The adsorption tube 72 is installed on the surface of the vacuum generator body 71.
