    • A pattern plate for making moulds intended for use in the production by sand casting of window seals or similar articles having an undercut bead, includes a plate, a fixed exterior part, an axially movable interior part and a elastomeric ring connecting the interior and exterior part. The interior part moves axially over a short path defined within the exterior part by mechanical stops between an extended position, to which it is pushed back by springs, and a retracted position which it assumes through the action of the compaction pressure. During compaction, an annular elastomer ring located between the interior and exterior parts compresses to compact the mold material in a lateral direction. Upon release, the elastomeric ring returns to its original position facilitating the removal of the mould.
    • 用于制造模具的模板用于制造窗口密封件或具有底切珠的类似物品的制造中,包括板,固定外部部件,可轴向移动的内部部件和连接内部和外部部件的弹性体环 。 内部部分通过机械止动件在外部部件内限定的短路径上轴向移动,该延伸位置被弹簧推回到其延伸位置与通过压实压力的作用而呈现的缩回位置之间。 在压实期间,位于内部和外部之间的环形弹性体环压缩以沿横向压紧模具材料。 松开时,弹性环返回到其初始位置,便于移除模具。

    • An adjustable filler means for molds and method thereof which comprises a molding flask adapted to adjustably receive and support a plurality of mold-contouring fingers arranged to be functionally held in spaced relation to a pattern within the flask, so as to be readily moved and adjusted to conform to any irregular contour of such pattern or core print disposed within the flask, and wherein a contour medium is provided between the fingers and the surface of the pattern to establish a contoured space between the fingers and pattern, whereby molding sand is provided therein to form the face of a mold or core.
    • 一种用于模具的可调节填充装置及其方法,其包括适于可调节地接收和支撑多个模具轮廓的手指的模制烧瓶,所述多个模具形状的手指被布置成在功能上保持与烧瓶内的图案间隔开的关系,以便容易地移动和调整 以符合布置在烧瓶内的这种图案或芯纹的任何不规则轮廓,并且其中在指状物和图案的表面之间设置轮廓介质,以在指状物和图案之间建立轮廓空间,由此在其中提供型砂 以形成模具或芯的表面。
