Description
本創作係有關於一種變模溫模具，尤其是指一種能使模具溫度快速且均勻的傳導至模穴，改善充填階段塑料的流動性，並可減少熱源使用量，達到節能效果之變模溫模具的創新結構。This creation is about a variable mold temperature mold, especially a variable mold temperature that can make the mold temperature transfer to the cavity quickly and evenly, improve the fluidity of the plastic in the filling stage, and reduce the heat source usage to achieve energy saving effect. The innovative structure of the mold.
在射出成型的製程中，模具的溫度左右著成型產品品質的優劣，主要是因為模具溫度會影響射出成型時塑料的流動性，導致產品在成型後會產生收縮、變形、翹曲、表面品質（如縫合線、光澤度、表面浮纖、殘留應力）等問題。因此，模具溫度的控制一直備受重視，且持續被探討，並研發出各種模具溫度控制的方法與結構，以提升射出產品的良率，例如變模溫模具即是為改善射出成型時塑料的流動性而設計。In the injection molding process, the temperature of the mold affects the quality of the molded product, mainly because the mold temperature affects the fluidity of the plastic during injection molding, resulting in shrinkage, deformation, warpage, and surface quality after molding. Problems such as suture, gloss, surface fibrillation, residual stress, etc. Therefore, the control of mold temperature has been highly valued and has been continuously explored, and various methods and structures for mold temperature control have been developed to improve the yield of injection products. For example, the mold temperature change mold is to improve the plasticity during injection molding. Designed for fluidity.
傳統射出成型之模具溫度設定是以恆溫控制方式，利用循環水路或油路控制模具溫度，但此種恆溫式的控制，無法因應射出成型時各個階段的溫度需求，因此能隨著射出成型的不同階段提供不同溫度的變模溫模具因應而生。變模溫射出成型在日本被稱為「急冷急熱」RHCM，在英國則稱為RTC。The mold temperature setting of the traditional injection molding is controlled by a constant temperature control method, and the temperature of the mold is controlled by the circulating water circuit or the oil circuit. However, the constant temperature control cannot respond to the temperature requirements of each stage during the injection molding, and thus can be different with the injection molding. The stage provides mold temperature molds of different temperatures in response to the response. Variable mold temperature injection molding is called "quick and hot" RHCM in Japan and RTC in the UK.
目前常見的變模溫加熱方式有感應加熱與紅外線加熱變模溫兩種方式。雖然感應加熱與紅外線加熱變模溫方式皆具有可減少模具內之控溫迴路，使模具機構設計更有彈性之優點；但感應加熱變模溫方式因為線圈纏繞與彎曲方式有所限制，容易造成加熱不均；而紅外線變模溫加熱方式也因為必須使用經由光學設計的反射光罩才可得到均勻模面加熱；因此，在實際使用上皆有難以解決的缺失。At present, the common variable temperature heating methods are induction heating and infrared heating to change the mold temperature. Although both induction heating and infrared heating variable temperature mode have the advantages of reducing the temperature control loop in the mold and making the mold mechanism design more flexible; however, the induction heating variable temperature method is limited due to the limitation of coil winding and bending. The heating is not uniform; and the infrared variable temperature heating method also obtains uniform mold surface heating because the optical mask is required to be optically designed; therefore, there is an inconvenience in practical use.
今，本創作人即是鑒於上述射出成型模具在實際的實施使用上所產生的缺失之處，而研創出本創作。Nowadays, the creator has created the creation in view of the shortcomings caused by the above-mentioned injection molding die in actual implementation and use.
