得ることができるが、一般に外型２個以上の割型
としているために、脱型して得たマネキンの表面
に割型の接合部により「バリ」が生じる。 The fleshing of a mannequin with such a skeleton needs to be made of a flexible and elastic material, which can be achieved by injecting an elastic polymer material latex into the mold together with a reaction initiator, but generally it is necessary to fill the mold with two or more outer molds. Because it is made into a mold, "burrs" occur on the surface of the demolded mannequin due to the joints of the split molds.
ところが、マネキンの素材が弾性高分子材料で
ある場合、前記「バリ」を消失させるための研摩
や切削処理が著しく困難である。 However, when the material of the mannequin is an elastic polymer material, it is extremely difficult to perform polishing or cutting treatments to remove the "burrs".
また、この「バリ」を生じたまま無理に脱型さ

面に醜い傷を生じて、マネキンとしての商品価値
を著しく低下する欠点がある。 In addition, if the mold is forcibly removed with these "burrs" still formed, ugly scratches will occur on the smooth outer surface, which resembles human skin, and this will significantly reduce the commercial value of the mannequin.
この発明は、上記の問題を解決し、成形時の

In order to solve the above problems, this invention
Inside the undivided outer mold, which is formed to imitate the shape of the upper body of a human body and has an open torso and a core insertion port in the head and shoulders, hollow sections are formed from the open part and the core insertion port, respectively. A forming core is loaded, and a latex made of an elastic polymer material is injected together with a reaction initiator into the hollow space formed between the core and the outer mold. After the reaction is completed, the core is removed and then covered. This method of manufacturing a mannequin is characterized in that the molded product is removed from the mold by pushing it out into an open part while shrinking and twisting from each core insertion port.

With the core assembled in the outer mold, an elastic polymer material latex is injected into the outer mold and polymerized (or crosslinked). After polymerization (or crosslinking) of the injected material, the core is removed from the outer mold and covered. The molded product is extracted from the open part of the outer mold. During this demolding, a hand or an instrument is inserted through the core insertion opening, and the molded product is crushed and twisted while being pushed toward the opening.
