The invention discloses a double-color mould multi-sliding-block linkage mechanism. The double-color mould multi-sliding-block linkage mechanism comprises a water gap plate and a limiting rod connected to the top of the water gap plate, wherein a falling sliding block spring is arranged on one side of the limiting rod; the top of the falling sliding block is connected with a first falling sliding block; the top end of the limiting rod penetrates through a sliding block and is connected with a sliding block guide block; a mould opening mechanism is arranged on one side of the limiting rod; second falling sliding blocks are arranged on two sides of the sliding block correspondingly; a spring is arranged in the sliding block, and the two ends of the spring are fixed to a reverse abutting mechanism. On the original base, the multiple stages of sliding blocks and the multi-sliding-block mechanism are adopted to move step by step, and automatic demoulding is adopted, so that labor cost is greatly reduced, and the problems of poor safety and the like are solved. The double-color mould multi-sliding-block linkage mechanism is provided with the four second falling sliding blocks, and a mould with a large number of reverse buckles in the four freedom-degree directions is adopted. By adopting the mechanism, the quality of the mould can be greatly improved, and the product production period can be greatly shortened.
