Description

Technical Field

[0001] The invention relates to the technical field of plastic sealing process, in particular to a high-efficiency and stable turnover mechanism suitable for a double injection molding system. Background Art

[0002] In the semiconductor back-end industry, the packaging and testing industry is a key link, and packaging is even more important. The traditional packaging system is a servo-controlled fully automatic packaging system. One press machine produces two frames in one mold. For the flip mechanism, there are no requirements for appearance and weight, and the design of the flip mechanism is not too difficult; with the expansion of customer production capacity, the dual injection molding system has achieved one press machine with four frames in one mold. For products with specific flow channels in the upper mold, due to the appearance of the four-piece frame and the weight of the mechanism, the flip mechanism has become a bottleneck restricting automated production.

[0003] The traditional packaging system can only produce two-piece frames in one mold, while the double injection system has doubled its capacity, and one mold can produce four-piece frames. In the process of automated production, some special types of chips have encountered problems. In order to stabilize production and meet special process requirements, the flow channel for glue inlet can only be set in the upper mold during mold design. Since double injection molding is a four-piece frame flip, compared with the traditional flip mechanism, the size is twice as large, and the flip mass is doubled, which causes troubles in the design of the flip mechanism. Therefore, the present invention proposes an efficient and stable flip mechanism suitable for the double injection system. Summary of the invention
