    • The invention relates to a casting tool for the production of castings, particularly for the production of cores (90) for sand castings, comprising a supporting device consisting of a first and a second supporting unit (10, 20, 50, 60) capable of being moved in a joining direction (2) toward each other, and comprising at least two mold elements (30, 40), of which a first mold element (30) is attached to the first supporting unit (10, 20) and a second mold element (40) is secured to the second supporting unit (50, 60), which mold elements (30, 40) each have a mold recess (33, 43), which mold recesses (33, 43) in the mold elements (30, 40) together define the shape of at least one casting core to be produced (90) when the first and second mold elements (30, 40) bear against each other.According to the present invention, one of the supporting units (10, 20) has a first peripheral frame (20) that surrounds the mold element (30) attached to said supporting unit (10, 20), and the frame (20), as multi-segment frame, is composed of at least two frame segments (22, 24, 26) joined together by positively effective securing means.The use thereof as a very simply and quickly produced core-casting tool.
    • 本发明涉及一种用于生产铸件的铸造工具,特别是用于生产用于砂铸件的铸芯(90)的铸件,其包括由第一和第二支撑单元(10,20,50,60)组成的支撑装置,所述支撑装置能够 沿着连接方向(2)彼此移动,并且包括至少两个模具元件(30,40),其中第一模具元件(30)附接到第一支撑单元(10,20),第二模具元件 模具元件(40)固定到第二支撑单元(50,60),模具元件(30,40)各自具有模具凹槽(33,43),模具元件(30,40)在模具元件中模制凹口(33,43) 30,40)当第一和第二模具元件(30,40)彼此抵靠时,一起限定待生产的至少一个铸造芯(90)的形状。 根据本发明,支撑单元(10,20)中的一个具有围绕附接到所述支撑单元(10,20)的模具元件(30)的第一外围框架(20)和框架(20), 作为多段框架由至少两个由积极有效的固定装置连接在一起的框架段(22,24,26)组成。 作为一种非常简单而快速生产的铸造工具的使用。

    • A seal for surrounding the cavity in a core box made up of a pair of mating members meeting at an interface in which a cavitysurrounding channel of greater than semicircular section is formed in but one of the members. The channel carries coextensively therewith a tubular elastomer seal of somewhat greater diameter than the channel so as to initially project from the channel in parabolic fashion, the parabolic portion being deformed into the channel as the two members are brought tightly together.
    • 用于围绕由一对配合构件构成的芯盒中的空腔的密封件,所述一对配合构件在其中形成有大于半圆形截面的腔周围通道的界面处会合,但是其中一个构件中。 通道与管道弹性体密封件共同延伸,该管状弹性体密封件的直径略大于通道的直径,以便最初以抛物线方式从通道突出,当两个部件紧紧地连在一起时,抛物线部分变形为通道。
