    • This invention presented is a method of polymerizing colored patterns inside a mode, comprising a top pattern, a middle pattern and a bottom pattern, enabling a meltable object to be infused into the mode for forming the mold shape. The bottom pattern enables a thermal-transfer film to be put thereon, and then the middle pattern keeps down the perimeter of the thermal-transfer film for fixing the film and forming a vacuity, thereby the thermal-transfer film is able to completely contact the cavity inside the bottom pattern; subsequently, a meltable object is infused into the mold after the mold is closed. Seeing that the thermal-transfer film is a thermoplastic polymer having a similar property to the meltable object, therefore, the thermal-transfer film is able to be directly printed on the meltable object surface by way of the hot temperature of the meltable object. The transfer printing process is then finished after the meltable object inside the mold is shaped. Therefore, the invention possesses the characteristics of simultaneously shaping and transfer printing without an additional increase in temperature on the thermal-transfer film, moreover, the invention is more applicable to objects with cambered surfaces and/or large areas.
    • 本发明提供了一种在模式内聚合着色图案的方法,其包括顶部图案,中间图案和底部图案,使得可熔融物体能够注入模具以形成模具形状。 底部图案能够将热转印膜放在其上,然后中间图案保持用于固定薄膜的热转印膜的周边,并形成真空,由此热转印膜能够完全接触 底部图案内腔; 随后,在模具闭合之后将可熔物体注入模具中。 看到热转印膜是与可熔物体具有相似性质的热塑性聚合物,因此,热转印膜能够通过可熔物体的热温直接印刷在可熔物体表面上。 然后在模具内部的可熔化物体成形之后完成转印印刷工艺。 因此,本发明具有同时成型和转印印刷的特性,而不会在热转印膜上另外增加温度,而且本发明更适用于具有弧形表面和/或大面积的物体。

    • The present invention is related to an automatic tool-changing mechanism adapted to be used in a machining center and including a power source, a machine frame and an automatic tool changing device secured to the machine frame, wherein the automatic tool changing device includes a tool changer secured to the machine frame for functioning in tool-grasping, tool-extracting, tool-interchanging, tool-inserting and tool-returning motions; a rotating device secured to a driving shaft and coupled to the tool changer and a swing arm device, the rotating device including a first and second rotating elements in which the first rotating element is used for enabling a to-and-fro swing motion of the swing arm device and the second rotating element is used for enabling a to-and-fro rotary motion of the tool changer to perform the tool-grasping, tool-interchanging and tool-returning motions; and the swing arm device having an intermediate portion thereof pivotally coupled to the machine frame and a first end portion and a second end portion thereof pivotally coupled to the first rotating element and the tool changer, respectively, so as to swing to and fro stably in response to an operation of the first rotating element to facilitate the tool-extracting and tool-inserting motions of the tool changer. The present invention has less mechanical elements compared to the conventional mechanism so that the assembling time can be reduced. In addition, the present invention can effectively lower the rocking of the tool-changing arm upon swinging so as to enhance the positioning precision.
