Rubber plugging head, foaming plate and foaming method

The invention provides a glue plugging head, a foaming board and a foaming method, and belongs to the technical field of foaming, the glue plugging head comprises a clamping part and a glue plugging part, and the clamping part is used for being clamped on a filling opening of a foaming space. And the rubber blocking part is arranged on one side of the clamping part, a discharging opening is formed in the rubber blocking part and is opened when the foaming material is poured, and after the foaming material is poured, the discharging opening shrinks, so that the foaming material is blocked in the foaming space. The glue blocking head is novel in structure, can play a role in preventing foaming materials in the foaming space from overflowing in the foaming process, and can ensure the foaming quality of a foaming plate. 本发明提供了一种堵胶头、发泡板及发泡方法，属于发泡技术领域，该堵胶头包括卡接部和堵胶部，卡接部用于卡接在发泡空间的灌注口上。堵胶部设置在卡接部一侧，堵胶部上设有出料口，出料口在灌注发泡料时被撑开，发泡料灌注完成后，出料口收缩使得发泡料被堵塞在发泡空间内。该堵胶头结构新颖，能够在发泡过程中起到阻止发泡空间中的发泡料溢出的作用，能够保证发泡板的发泡质量。
