BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The embodiments of the present invention are described below in conjunction with the accompanying drawings, wherein:

[0014] Figure 1 This is a schematic structural diagram of a paper cup mold assembly provided by the present invention. DETAILED DESCRIPTION

[0015] The specific embodiments of the present invention are further described in detail below based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0016] Please refer to Figure 1 , which is a structural schematic diagram of a paper cup mold assembly provided by the present invention. The paper cup mold assembly is used for placing paper cups (not shown) during the paper cup crimping process. The paper cup mold assembly includes a mold fixing rod 10, a pushing device 20 arranged at one end of the mold fixing rod 10, and a mold body 30 arranged at the other end of the mold fixing rod 10. The paper cup mold assembly should also be connected to an air source (not shown), and it should also include some other functional modules, such as connecting components, mounting components, etc., which should be technologies well known to those skilled in the art, so they will not be described in detail here.

[0017] An air circuit 11 is provided inside the mold fixing rod 10, and the air circuit is connected to the air source. The mold fixing rod 10 is used to connect the pushing device 20 and the mold body 30. The mold body 30 is fixed on the mold fixing rod 10. The air circuit 11 inside the mold fixing rod 10 is connected to the air source to enable relative movement between the pushing device 20 and the mold body 30.

[0018] The pushing device 20 includes a polished rod 21 sleeved on the mold fixing rod 10, a bearing assembly 22 arranged at one end of the polished rod 21 away from the mold fixing rod 10, and a cup pushing block 23 arranged on the polished rod 21 close to the mold body 30. The polished rod 21 is a standard part, so it is not repeated here. The bearing assembly 22 includes a bearing support block 221 connected to the polished rod 21, and a CF bearing 222 installed on the bearing support block 221. The polished rod 21 is sleeved on the mold fixing rod 10 so that a chamber 25 is formed between the polished rod 21 and the mold fixing rod 10, and the chamber is connected to the gas path 11. Since the gas path 11 is connected to an external gas source, when the gas in the chamber 25 is discharged, the external air pressure pushes the cup pushing block 23 toward the mold body 30, so that the paper cup placed on the mold body 30 is ejected. The cup pushing block 23 includes a cup pushing block body 231 and an abutment portion 232 arranged in the circumferential direction of the cup pushing block body 231. The diameter of the abutment portion 232 is larger than the diameter of the end surface of the mold body 30 close to the pushing device 20, so as to facilitate the placement and pushing out of the paper cup. The mold fixing rod 10 is provided with a spring 15, and the spring 15 is located below the cup pushing block 23. When the cup pushing block 23 completes the cup pushing action, the cup pushing block 23 is reset under the action of the spring 15.

[0019] The mold body 30 includes a frustum section 31 and a straight section 32 connected to the frustum section 31. The arrangement of the frustum section 31 and the straight section 32 allows the paper cup to be better placed on the mold body 30. The taper of the frustum section 32 is 4.0° to 5.5°, so that the paper cup can be easily placed and removed after crimping.

[0020] A through slot 33 is formed on the end surface of the mold body 30 close to the pushing device 20, and a gasket 34 is formed at one end of the through slot 33 away from the pushing device 20. The mold fixing rod 10 is inserted into the through slot 33 and fixedly connected to the gasket 34. At least two bearings 35 are also provided between the mold body 30 and the mold fixing rod 10. Each of the bearings 35 is provided with a bearing hole retaining spring 36, and the bearing hole retaining spring 36 cooperates with the bearing 35 to position the mold fixing rod 10 and the mold body 30.

[0021] Compared with the prior art, the present invention provides a paper cup mold assembly, which connects a pushing device 20 and a mold body 30 through a mold fixing rod 10, an air path 11 is provided inside the mold fixing rod 10, a chamber 25 connected to the air path 11 is formed between the pushing device 20 and the mold fixing rod 30, a through groove 33 is provided on the mold body 30, a gasket 34 for fixing the mold fixing rod 10 is provided in the through groove 33, and at least two bearings 35 are provided between the mold body 30 and the mold fixing rod 10. Such a structure is simple, and the paper cup after crimping can be automatically removed, with a high degree of automation, improved production efficiency, and meeting modern production needs.

[0022] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
