Title
(EN) PREPARATION METHOD FOR DOUBLE-HARDNESS MOLDED FOAMED SOLE, AND FOAMED SOLE THEREOF
(FR) PROCÉDÉ DE PRÉPARATION POUR SEMELLE FOAMÉE MOULÉE À DOUBLE DURETÉ ET SEMELLE FOAMÉE CORRESPONDANTE
(ZH) 一种双硬度模压发泡鞋底的制备方法及其发泡鞋底
Abstract
(EN) Disclosed in the present invention is a preparation method for a double-hardness molded foamed sole, comprising the following steps: preparing material grains A; preparing material grains B; pouring the material grains B into a material suction barrel, and ejecting the material grains B by means of a primary ejection machine to obtain a cold blank; putting the cold blank at the edge of a small vacuum foaming mold, pouring the material grains A to the middle part of the small vacuum foaming mold, closing the mold, heating for foaming, and automatically opening the mold after foaming is finished, to obtain a foamed primary blank; putting the foamed primary blank into an oil pressure mold, closing the mold, pushing the mold into a heating station of a secondary foam forming machine, pressurizing and heating; and then transferring the oil pressure mold to a cooling station, pressurizing, spraying water to cool the mold, pulling out the mold, and taking out a finished product, to obtain the double-hardness molded foamed sole. According to the foamed sole of the present invention, the hardness of the surrounding circle is 55C-62C, the hardness of the middle part is 35C-43C, and the hardness of the middle part is low, such that the comfort of the sole can be improved, the resilience rate is high, the shock absorption performance is good, the hardness of the surrounding circle is high, and the defects of easy collapse of soft materials, high compression denaturation rate, and severe wrinkling can be improved.
(FR) La présente invention concerne un procédé de préparation d'une semelle foamée moulée à double dureté comprenant les étapes suivantes : la préparation de grains de matériau A ; la préparation de grains de matériau B ; le versement des grains de matériau B dans un cylindre d'aspiration de matériau et l'éjection des grains de matériau B au moyen d'une machine d'éjection primaire pour obtenir une ébauche froide ; le placement de l'ébauche froide au niveau du bord d'un petit moule de foamage sous vide, le versement des grains de matériau A sur la partie centrale du petit moule de foamage sous vide, la fermeture du moule, le chauffage pour le foamage et l'ouverture automatique du moule une fois le foamage terminé pour obtenir une ébauche primaire foamée ; le placement de l'ébauche primaire foamée dans un moule à pression d'huile, la fermeture du moule, la poussée du moule dans une station de chauffage d'une machine de foamage secondaire, la mise sous pression et le chauffage ; puis le transfert du moule de pression d'huile vers une station de refroidissement, la mise sous pression, la pulvérisation d'eau pour refroidir le moule, la traction du moule et l'extraction d'un produit fini pour obtenir la semelle foamée moulée à double dureté. Selon la semelle foamée de la présente invention, la dureté du cercle environnant est de 55C-62C, la dureté de la partie centrale est de 35C-43C et la dureté de la partie centrale est faible, de sorte que le confort de la semelle peut être amélioré, le taux d'élasticité est élevé, la performance d'absorption des chocs est bonne, la dureté du cercle environnant est élevée et les défauts d'effondrement facile de matériaux mous, de taux de dénaturation à haute compression et de plissement sévère peuvent être améliorés.
(ZH) 本发明公开了一种双硬度模压发泡鞋底的制备方法,包括以下步骤:制备料米A;制备料米B;将料米B倒入吸料桶,经一次射出机台射出,得到冷胚;将冷胚放在真空小发泡模具的边沿,再将料米A倒入真空小发泡模具中间,合模、升温发泡,发泡结束,自动开模,得到发泡初胚;将发泡初胚放入油压模具,合模,推入二次发泡成型机的加热站位,加压、升温;然后将油压模具转移至冷却站位,加压、淋水冷却模具,拉出模具,取出成品,即得到双硬度模压发泡鞋底。本发明的发泡鞋底,周围一圈的硬度55C-62C,中间的硬度35C-43C,中间硬度低,有利于提高鞋底舒适性,回弹率高,减震性能好;周围一圈的硬度高,有利于改善软料容易塌陷、压缩变性率大、起皱厉害的缺陷。
