Method for preparing pad body with concave-convex structure and mold for preparing pad body with concave-convex structure

Abstract

The invention provides a method for preparing a pad body with a concave-convex structure and a mold for preparing the pad body with the concave-convex structure. A first elastic sheet is pasted on a second elastic sheet, the first elastic sheet is made of a closed-hole type elastic material, the second elastic sheet is made of an open-hole type elastic material, and the first elastic sheet and the second elastic sheet which are combined are heated. And finally, negative pressure suction is carried out on the heated first elastic sheet and the heated second elastic sheet from one side of the second elastic sheet by utilizing the mold and simultaneously cooling is carried out, so that the first elastic sheet and the second elastic sheet can be deformed by utilizing the concave-convex structure of the mold and are cooled and shaped, thereby obtaining the pad body with the concave-convex structure.

Description

technical field [0001] The invention relates to elastic pad technology, in particular to a pad body method with a concave-convex structure and a mold for preparing a pad body with a concave-convex structure. Background technique [0002] Nowadays, elastic mats with concave-convex structures on the surface can provide anti-slip and shock-absorbing functions, and are suitable for sports (such as yoga mats). [0003] The existing method of making the elastic cushion does not need to prepare a base material with a concave-convex structure and laminate it with another elastic sheet, and then heat and mature or foam it, as shown in China Taiwan Patent No. I584950 , that is, it is formed by embossing with a mold during the process of laminating the two elastic sheets, as shown in China Taiwan Publication No. 200916156. [0004] The concave-convex structure base material used in the Chinese Taiwan No. I584950 patent needs to be pre-fabricated, and the Chinese Taiwan No. 200916156 p...

AI Technical Summary

Problems solved by technology

[0004] The concave-convex structure base material used in the Chinese Taiwan No. I584950 patent needs to be pre-fabricated, and the Chinese Taiwan No. 200916156 public case is to solve the gap between the elastic sheets when the existing closed hot pressing mold is thermally pasted several elastic sheets. The problem that the generated air bubbles cannot be discharged will affect the quality of the product. The elastic sheets are punctured in advance to generate many holes. When heat laminating in the closed hot pressing mold, the air extraction method can be used to allow the generated air bubbles to pass through. The pre-punctured holes are extracted and eliminated, and the manufacturing process is more complicated
