    • The device is constituted by a prism-shaped structure which has flat faces, is internally hollow and is rotatably mounted, with preset stops, about a horizontal axis which lies at right angles to the direction of movement of the casting head. A core box is mounted on at least two oppositely arranged faces of the rotating prism-like structure and supports a lower half-mold and associated plates for extracting the finished core; each one of the lower half-molds can be placed in succession, upon rotation of the prism-like structure, at the movable upper half-mold so as to allow, by means of a single upper half-mold, to mold a core in each one of the lower half-molds and to simultaneously extract the previously finished core from the oppositely arranged half-mold.
    • 该装置由棱柱形结构构成,该棱柱形结构具有平坦的表面,内部是中空的,并且围绕与铸造头的移动方向成直角的水平轴可旋转地安装有预设的止挡件。 芯盒安装在旋转棱柱状结构的至少两个相对布置的面上,并支撑下半模和相关板以提取成品芯; 下半模中的每一个可以在棱镜状结构旋转时被连续地放置在可移动的上半模上,以便借助于单个上半模可以将芯体模制成 每个下半模,并且从相对布置的半模同时提取先前成品的芯。

    • A machine for making molds and molding cores (126) includes a pair of mold boxes (42a, 42b) removably mounted on a frame (60) for rotation between an upright, molding position in which molding mateiral is introduced into the molding cavity of the molding boxes (42a, 42b) by a carrier (26) and an inverted discharge position in which the mold (126) is removed from the boxes by a mold receiving assembly (76). A pressure head assembly (46) both compresses molding material within the molding cavity and introduces a catalyst gas into the cavity for curing the molding material. A system for removing the spent gas from the molding cavity includes a pair of gas receiving chambers (122a, 122b) integral with the frame (60) which receives gas through the bottom of the mold boxes (42a, 42b) and an exhaust assembly (68, 70) which is selectively coupled with exhaust ports (124a, 124b) in the chambers (122a, 122b ). A mold transfer carriage (84) transfer molds (126) discharged from the mold boxes (42a, 42b) to either of two lateral positions and can be employed to automatically change mold boxes (42a, 42b) which are mounted on the frame (60) by quick release connections (62, 64, 134).
    • 一种用于制造模具和模制芯(126)的机器包括一对可拆卸地安装在框架(60)上的模具盒(42a,42b),用于在直立的成型位置之间旋转,在该模制位置中,成型材料被引入到模具 模具盒(42a,42b)通过托架(26)和倒置的排出位置,模具(126)通过模具接收组件(76)从盒子中取出。 压头组件(46)都压缩成型腔内的成型材料,并将催化剂气体引入空腔中以固化成型材料。 用于从成型腔中去除废气的系统包括与框架(60)成一体的一对气体接收室(122a,122b),其接收通过模具箱(42a,42b)的底部的气体和排气组件 68,70),其选择性地与腔室(122a,122b)中的排气口(124a,124b)联接。 模具转移支架(84)将从模具箱(42a,42b)排出的模具(126)转移到两个横向位置中的任一个,并且可以用于自动地更换安装在框架(60)上的模具箱(42a,42b) )通过快速释放连接(62,64,134)。
