[0006] Further, the drive pipe piece is cylindrical tube, one end of the cylindrical tube is connected with the through-hole, and the other end is connected with aeration structure.

[0007] Further, the drive pipe piece includes a bar and a sleeve, one end of the bar is connected with the inner wall of the ellipsoidal mold, the bar sleeve is loosely fitted on the bar, and the sleeve is connected with the through-hole.

[0008] Further, the ellipsoidal mold is formed by a plurality of thin steel sheets.

[0009] Further, the outer surface of the ellipsoidal mold is provided with a surface layer.

[0010] Further, the surface layer is mesh-like.

[0011] Further, the material of the surface layer is silica gel.

[0012] Compared with the prior art, the paper-plastic spherical forming die has the following beneficial effects:

[0013] The hollow elliptical spherical die and the driving pipe are arranged in the paper-plastic spherical forming die, the spherical die is soaked in the wet paper-plastic, the paper-plastic is attached to the surface of the elliptical spherical die, thereby forming a spherical product, and the elliptical spherical die can be controlled to shrink or expand through the driving pipe, thereby adjusting the shape of the elliptical spherical die to be circular or different sizes of elliptical, that is, one die can process products with different shapes according to actual requirements, can meet more requirements, and has high flexibility.

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application. EMBODIMENT

[0020] Referring to Figures 1-4The application discloses a forming mold for paper-plastic and soft material ellipsoidal products, which comprises an ellipsoidal mold and a driving pipe for driving the ellipsoidal mold to expand or contract. The ellipsoidal mold is made of thin steel sheets which can be deformed under the action of air or external force. The ellipsoidal mold is hollow and has a surface covered with tiny holes. The ellipsoidal mold is provided with a through hole 2, and the driving pipe is connected to the through hole 2. In the embodiment, the driving pipe is a cylindrical pipe 3, one end of which is connected to the through hole 2 and the other end is connected to an air inlet structure which is an air pump or other equipment with the function of inflating.

[0021] In use, the cylindrical pipe 3 is inflated to expand the ellipsoidal mold 1 to a suitable shape, and then the ellipsoidal mold 1 is immersed in a cylinder filled with paper-plastic, so that the paper-plastic is attached to the surface of the ellipsoidal mold 1. When the paper-plastic is dried, a hollow paper-plastic product is formed. Then the cylindrical pipe 3 is deflated to a strip shape, and the product is taken out from the through hole 2. The mold can also be used for processing spherical products made of other materials, such as silica gel. The ellipsoidal mold 1 is immersed in a cylinder filled with liquid silica gel, so that the liquid silica gel is attached to the surface of the ellipsoidal mold 1. Then the ellipsoidal mold 1 is placed in a high-temperature drying device to heat the liquid silica gel, and the formed product is taken out from the device.

[0022] In the embodiment, the outer surface of the ellipsoidal mold 1 is provided with a surface layer which makes the inner wall of the formed spherical product have a desired shape. The surface layer is made of silica gel and has a mesh structure. Embodiment

[0023] The embodiment is another embodiment of the application. The difference between the embodiment and the first embodiment is that the driving pipe comprises a strip-shaped rod and a sleeve. One end of the strip-shaped rod is connected to the inner wall of the ellipsoidal mold 1, the sleeve is loosely sleeved on the strip-shaped rod, and the sleeve is connected to the through hole 2. The sleeve is pushed to slide on the strip-shaped rod, so as to approach or move away from the top end of the strip-shaped rod, thereby expanding or contracting the ellipsoidal mold 1. That is, the structure of the driving pipe in the embodiment is different from that in the first embodiment, and the structure of the driving pipe can be selected in multiple ways to control the expansion and contraction of the ellipsoidal mold 1.

[0024] The above description is merely that of a specific implementation of the present application, which enables those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Accordingly, the present application is not to be limited to these embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
