Problems solved by technology

However, because the sponge elastic body itself is relatively soft, when its height is 5mm or above, the sponge elastic body is affected by molding during punching, and the pressure on the inside and outside of the mold is inconsistent, and the product will be deformed, resulting in a 'C' on the punched surface. 'shape or upward and downward slope, and the die-cutting size tolerance is usually above 1mm, and the defect rate is high

Embodiment Construction

[0018] The technical scheme of the present invention will be further elaborated below.

[0019] The above-mentioned production process for punching and deforming of a sponge elastic body comprises the following steps:

[0020] (1) Preparation and cutting: prepare a number of sponge elastic bodies required for the process. In this embodiment, the sponge elastic body includes a sponge body, a glue layer, and a release layer attached to the surface of both sides of the sponge body through the glue layer. The thickness of the sponge elastic body is not less than 5mm, and the density is 10-300kg / m 3 between. According to the size of the product, the sponge elastic body is cut out to the required width.

[0021] (2) Preparation of mold set: the mold set includes a plurality of molds arranged successively along the feeding direction of the sponge elastic body, and each mold includes an upper die, a lower mold corresponding to the upper die, and the upper die The mold is provided w...

Abstract

The invention discloses a production technology free of sponge elastomer punching deformation. Due to the fact that the shape periphery lines of products which need to be formed by punching sponge elastomers are decomposed into a plurality of lines, and curve segments and linear segments are scattered and then are engraved into different upper cutter dies; and the upper cutter dies are sequentially distributed in the feeding direction of the sponge elastomers, and therefore needed products can be obtained after the sponge elastomers are punched for many times in different steps. By means of the technology, the deformation degree of the punched faces of the sponge elastomers is effectively controlled, the die-cutting dimensional tolerance is within 0.3 mm, and the product percent of pass is increased.

Description

technical field [0001] The invention relates to a production process of a sponge elastic body which is not deformed by punching. Background technique [0002] At present, the method of punching sponge elastic body on the market is mainly to directly open a mold according to the shape of the customer's product to obtain the desired product. However, because the sponge elastic body itself is relatively soft, when its height is 5mm or above, the sponge elastic body is affected by molding during punching, and the pressure on the inside and outside of the mold is inconsistent, and the product will be deformed, resulting in a 'C' on the punched surface. 'shape or up and down slopes, and the die-cutting size tolerance is usually above 1mm, and the defective rate is high. Contents of the invention [0003] The object of the present invention is to provide a production process for punching the sponge elastic body without deformation of the punched product. [0004] In order to ac...
