However, when the terminal is to be mated with a plurality of slider inserts (e.g., two ends of the terminal are respectively inserted into different sliders), the sequence of movement of the sliders is sequentially time-sequential. When the sliding blocks have timing control requirements, an oil cylinder/air cylinder/motor and the like are added to realize movement decomposition of the sequential movement of a plurality of groups of sliding blocks, but the space occupied by the execution elements of the oil cylinder/air cylinder/motor for driving the sliding blocks is larger, and when the number of the die holes is more, the sizes of the arranged dies are larger, and a larger injection molding machine needs to be matched. Meanwhile, the terminal is difficult to implant in the inner slide of the die, and the molding period is longer. For the above situation, for the limited machine resources, under the condition of ensuring the strength and the function of the die, the die space can be reduced as much as possible, the molding period is shortened as much as possible, the improvement of the production efficiency is the direction that we need to take effort, and the following technical difficulties are mainly solved:
1. the terminal needs to be matched with a plurality of sliding block inserts, the mode of implanting the terminal needs to be simplified as much as possible, the implantation is convenient, the time is saved, and the molding period is shortened.
2. The movement of the sliding block has sequential requirements, and the conventional mechanism capable of realizing sequential actions occupies a relatively large space, so that a new optimization scheme needs to be found.
3. And the die arrangement is optimized as much as possible by combining the machine parameters, so that the die space is saved.
Based on this, there is also a need to provide a more rational solution to solve the current problem and achieve the above-mentioned object.
