    • A first aspect of the invention relates to the manufacture of disparate workpieces by the process of injection molding using a single base tool. The tool is made up of cavity and core halves, and each half is made up of separate, removable/interchangeable, inserts which, when combined in a particular order, form the workpiece-forming surface. All or any number of the inserts may be replaced with other inserts to alter the workpiece-forming surface and allow a large number of differently shaped workpieces (i.e. having different surface features and shapes) to be formed from a single base tool. In another aspect of the invention, the inserts are connected to respective thermally conductive cavity and core mounting plates, which are in turn connected to respective cavity and core heating/cooling plates so that insert-mounting holes need not be made in the heating/cooling plates.
    • 本发明的第一方面涉及通过使用单个基础工具的注射成型方法来制造不同的工件。 该工具由腔和半部组成,每一半由独立的,可拆卸/可互换的插入件组成,当以特定顺序组合时,该插入件形成工件形成表面。 所有或任何数量的插入件可以用其它插入件代替以改变工件形成表面,并允许从单个基础工具形成大量不同形状的工件(即具有不同的表面特征和形状)。 在本发明的另一方面,插入件连接到各自的导热腔和芯安装板,这些安装板又连接到相应的腔和芯加热/冷却板,使得在加热/冷却中不需要制造插入件安装孔 板。

    • An injection moulding tool with an insert that has a cross sectional profile closely matching that of a hole in a face of the tool, and the insert has a first and a second end, wherein the first end is located furthest away from the said face of the tool, and the second end is arranged to be coplanar with the face of the tool. The first end includes a cavity extending longitudinally into the insert so that a blind end is located at a predetermined distance from the face of the tool. A tube in the cavity is connected to a cooling or heating fluid conduit that extends in the vicinity of the blind end and the fluid impinges upon the blind end of the cavity. Heat is exchanged with the tool in the vicinity of the face of the tool, arid then flows out of the cavity into the void defined by the outer wall of the tube and the inner wall of the cavity.
    • 一种具有插入件的注射模制工具,其具有与所述工具的表面中的孔的横截面轮廓紧密匹配的截面轮廓,并且所述插入件具有第一和第二端,其中所述第一端位于距所述工具的所述表面最远的位置 工具和第二端被布置成与工具的面共面。 第一端包括纵向延伸到插入件中的空腔,使得盲端位于距工具的表面预定距离处。 空腔中的管连接到在盲端附近延伸的冷却或加热流体导管,并且流体撞击空腔的盲端。 热量与工具在工具表面附近更换,然后从空腔中流出到由管的外壁和腔的内壁限定的空隙中。
