Embodiment Construction

[0014] The present invention will be further described below in conjunction with specific examples, but not as a limitation to the present invention.

[0015] The invention relates to a stretching and pressing heat setting processing method, which adopts the method of layering and pressing down step by step, and uses a mold divided into multiple layers to process materials.

[0016] The layered step-by-step pressing method comprises the following steps:

[0017] A. First press the non-extending part (that is, the part that will wrinkle);

[0018] B. Press the part to be extended to the desired position, and set it at high temperature for tens of seconds.

[0019] The processing method of described mold comprises the following steps:

[0020] A. Make a model

[0021] B. Casting;

[0022] C. Grinding

[0023] D. After the module is divided, install the iron plate below;

[0024] E, planing die blank;

[0025] F, separation and cutting;

[0026] G. Assembly.

[0027] The...

Abstract

The present invention relates to a pulling-pressing thermosetting processing method, belonging to the field of mould processing technology. In the concrete, said invention relates to a pulling-pressing thermosetting processing method by using spongy fabric, foamed cotton, leather and fibre paper, etc as production material and utilizing mould to make high-temperature setting operation. It is characterized by that said invention adopts a layered step-by-step down-pressing mode to utilize the mould which is divided into several layers to make material processing.

Description

technical field [0001] The invention relates to the field of mold processing, and specifically provides a stretch-press heat-setting processing method for fabric sponge, foamed cotton, leather, fiber paper, etc., which are used for high-temperature shaping with a mold. Background technique [0002] The traditional heat-setting mold is a direct pressure type. Usually, there are only two male (upper) and female (lower) molds (except for the mold that needs to be crimped). When using this mold, the male mold is pressed down against the female mold Once, that is to complete a finalization job. It does not support any point of force around the part that needs to be extended, and there is no external pulling force. The pulling force required for its extension only comes from the elastic force of the extending part and its surroundings. When the required extension exceeds the elastic range, it will follow the upper mold Pressing down, the extension part cannot be extended, and the...
