傳統的射出成型模具應用於大量生產上，一般大多採用增加模穴數的方法，如此可以在一次成型過程中得到倍數的產品，若採用模具結構來克服，則大都使用疊模(stack mold) 或是縱列式模具 (Tandem mold) 俗稱 T 模的架購，而疊模僅適用於生產體積小、平板的成品(質量輕、壁板薄、投影面積大、大量生產)。T模則必需安裝額外的驅動裝置來做為模具開閉之輔助。
本研究在於提出一個新的 T 模機構，利用本身模具的開閉行為來達到新型式T 模機構之運動，以減少傳統T模必須安裝額外驅動裝置之成本。在研究過程中，首先搜尋現有的期刊、論文、專利等相關知識文件，結合現有之技術，先提出一個機構的初步概念，在新型式的 T 模機構開發中，首先提出一個凸輪型式搭配卡鉤的機構觀念，以模具的開合的週期運動，使凸輪機構做週期性的轉動，再利用凸輪推動卡鉤做為T模中隔板間兩側模板的卡合，在研究過程中並利用改良式分群法TRIZ 對整體新型式之 T 模機構做逐步之分析及改善，以滿足機構之合理性，完成後之設計，首先利用Pro/Engineer 建立理論模型，並利用Pro/Mechanism 針對理論模型做動態模擬，以確定機構在運作中的動作順利且無干涉。確認模擬之機構動作正常後，再利用真實模型驗證新型式T模機構之可行性。最後設計一組 T 模產品之模具圖並結合新型式之 T 模機構，針對其產品以Moldex-3D 執行模流分析，以確保本文所研發之新型式T模機構是可以被實際應用在模具上。
本文所得之新型式T模機構，利用模具本身之開合的週期性行為帶動凸輪達到週期性之卡合，可免去一般舊有 T 模機構需安裝額外驅動機構之缺點，節省成本並因全機械式機構的使用可降低故障比率。

The conventional injection molds applied to mass production, and this method mostly increases cavities or varies the mold structure to get multiple products in the period process. As to the mold structure, some of the molds makers use the stack molds or tandem molds to achieve this purpose. But the product categories of stack molds were limited to fabricate thin wall and flat products. The tandem molds need extra electronic drivers to make the mechanism work.
This research aims to propose the new mechanism, which utilizes open /close behavior of the mold to drive the locking system, replaces the electronic drivers of the original tandem molds. Firstly, we search the journals, theses and patents combining with the existing mold knowledge to create a new mechanism concept. The concept of new mechanism, composed of a cam set and locking system, utilizing open /close period behavior of the mold to make the cam set rotate and locking system alternately work. The cam set will push locking system to lock the hook of mid -plate with two side plate alternately.
For the reasonableness of mechanism, use “clustering TRIZ analysis method” to improve and accomplish this design. Secondly, use Pro/Engineer to create the theory mold and analyze dynamic simulation by pro/mechanism to verify the movement normal and no interference. Finally, make a set of mockup and put this new mechanism into a mold design and analyze the product by Moldex-3D software to make sure the mechanism could be implemented to a real mold.
The new mechanism for tandem molds, which utilizes open /close behavior of the mold to drive the locking system, replace the electronic driver of original tandem mold. Not only save the cost but reduce the fail rate by using the mechanical devices as well.
