Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogels, and in particular relates to a mold for producing hydrogels. Background Art

[0002] Hydrogel is a type of extremely hydrophilic three-dimensional network structure gel. It swells rapidly in water and can hold a large volume of water without dissolving in this swollen state. Due to the presence of a cross-linked network, hydrogel can swell and hold a large amount of water. The amount of water absorbed is closely related to the degree of cross-linking. The higher the degree of cross-linking, the lower the water absorption. This property is very similar to a soft tissue. The water content in the hydrogel can be as low as a few percent or as high as 99%. The aggregate state of the gel is neither completely solid nor completely liquid. The behavior of a solid is that it can maintain a certain shape and volume under certain conditions, and the behavior of a liquid is that solutes can diffuse or penetrate from the hydrogel.

[0003] During the production of hydrogel, it needs to be extruded into shape through a mold, and after the hydrogel is formed, it needs to be cut. However, the existing molds do not have the cutting function, which means that the cutting step requires other different devices, which results in a waste of human resources and equipment resources.
