摘要： A method of injection molding an over-molded article in which a cavity extension associated with a core is first moved to a disengaged position and the core is inserted into a first cavity having a defined volume in a first geometrical configuration. A first injection operation is performed into the first cavity to form a first layer of the article. The core is then removed from the first cavity with the first layer of the article on the core. The cavity extension is moved to an engagement position and the core and first layer are inserted into a second cavity. The second cavity and the cavity extension engage to form a composite cavity having a larger volume than the defined volume and define a second geometrical configuration. A second injection operation is performed into the composite cavity to over-mold the first layer to form the article. The core and cavity extension are separated from the second cavity to remove the article therefrom. The second cavity extension is moved relative to the core to remove the article from the core.

摘要： An injection molding machine for forming a multi-layer plastic article by over molding where the second layer of the article includes a portion having a different geometrical profile than the first. The injection mold machine comprises an array of one or more cores which engage arrays of one or more first cavity and arrays of one or more composite cavities. Each composite cavity is formed from the combination of a second cavity and a cavity extension which carries at least a portion of the different geometrical profile. In one embodiment, the cavity extension comprises a pair of cavity portions which are mounted adjacent the core to laterally moveable slides on a movable platen. In another embodiment, the cavity extension is a single element which is moved between a disengaged position wherein the core can be inserted into the first cavity and an engaged position wherein the core is inserted into the composite cavity.
摘要翻译：一种用于通过过模塑形成多层塑料制品的注射成型机，其中制品的第二层包括具有与第一层不同的几何形状的部分。注射模具机包括一个或多个芯的阵列，其接合一个或多个第一腔和一个或多个复合腔的阵列的阵列。每个复合空腔由第二腔体和空腔延伸部的组合形成，该第二腔体和腔体延伸部分承载不同几何轮廓的至少一部分。在一个实施例中，空腔延伸部包括一对空腔部分，这些空腔部分相对于芯部安装在可移动压板上的可横向移动的滑块上。在另一个实施例中，空腔延伸部是在分离位置之间移动的单个元件，其中芯可插入第一腔体中，并且接合位置，其中芯体插入到复合腔体中。
