| titleOfInvention | In-mold mold foam molding device for thermoplastic polymer particles and its molding method |
| abstract | The present invention discloses an in-mold mold foam molding apparatus for thermoplastic polymer particles and a molding method thereof. The device includes a supercritical fluid transfer system, a mold foaming system, a preheat quantitative material supply system and a moving rail. The supercritical fluid transfer system communicates with the mold foaming system. The structure of the present invention is simple. In the method of foam molding the polymer particles at one time, the polymer particles are directly injected into the molding cavity without being foamed in advance. In addition, it is not necessary to add water or a mold release agent for preventing adhesion. Moreover, in the compression / fusion molding process, the adhesive strength is excellent and the process is clean without heat molding with high-pressure steam. Therefore, it is suitable for polymer materials that are easily hydrolyzed. In addition, the amount of heat required in the processing process is relatively small, the heating efficiency of the polymer particles is excellent, and the temperature of the polymer particles is uniform, so that the bubbles are fine, the size is accurate, and the polymer particle micropores are lightweight. A foam molded product is obtained. In addition, production efficiency is improved and automated production is realized. Therefore, it is suitable for foam molding of a large number of polymer particles. [Selection diagram] Fig. 2 |
