Summary:The utility model relates to the field of hot die forging press machines, in particular to an embedded ejection device. Comprising a base plate and a counter bore formed in the base plate, a first channel and a second channel are formed in the side wall of the counter bore, a piston is coaxially installed in the counter bore, a piston rod is fixedly connected to the upper portion of the piston, a flange is arranged on the outer side of the piston rod in a sleeving mode, and a cylinder sleeve is arranged between the piston and the counter bore. According to the utility model, the cylinder sleeve is arranged between the piston and the counter bore, when the piston moves up and down in the cylinder sleeve, only friction force is generated between the cylinder sleeve and the piston, only the cylinder sleeve and the piston are abraded, the base plate is not abraded, and the service life of the base plate is prolonged. 本实用新型涉及热模锻压力机领域，特别是涉及一种嵌入式顶出装置。包括垫板以及设置在垫板上的沉孔，沉孔的侧壁上设置有第一通道和第二通道，沉孔中同轴安装有活塞，活塞上方固定连接有活塞杆，活塞杆的外侧套
