[0019] An elastic insert 4 is horizontally installed inside the slide seat 3 at the front end of the elastic insert connecting rod 6, and the front end of the elastic insert connecting rod 6 is in contact with the rear end of the elastic insert 4. A terminal foot forming fixture 2 is installed at the front end of the elastic insert 4 for clamping the product terminal.

[0020] A stopper 1 is vertically installed below the slide seat 3 at the position of the elastic insert 4. The stopper 1 is installed on the mold and is in a fixed static state. A safety protection device 5 is installed inside the bottom end of the elastic insert connecting rod 6.

[0021] The safety protection device 5 includes a push rod 501 and a reset spring 502. The push rod 501 is in a cross-shaped structure. One end of the push rod 501 is located inside the reset spring 502. The other end of the push rod 501 penetrates the elastic insert connecting rod 6 and the slide seat 3. In the initial state, the push rod 501 extends to the outside of the slide seat 3 by 0.2 mm. The front end of the push rod 501 faces the side of the stopper 1. Through the interaction between the safety protection device 5 and the stopper 1, the elastic insert connecting rod 6 is pushed to move in the moving groove 301.

[0022] A tilted pressure block 9 is installed at the tail end of the slide 3, and an elastic insert control block 8 is installed at one end of the tilted pressure block 9 for pushing the elastic insert connecting rod 6. The tail end of the slide 3 is tilted downward, and the side of the tilted pressure block 9 close to the slide 3 is tilted upward, and the tail end of the slide 3 cooperates with one side of the tilted pressure block 9 to facilitate close contact between the tilted pressure block 9 and the slide 3. An inclined guide column 7 is hinged inside the tail end of the slide 3, and one side of the inclined guide column 7 is tilted downward at the same angle as the tail end of the slide 3. The inclined surface of the inclined guide column 7 is flush with the inclined surface of the tail end of the slide 3, which is convenient for pushing the overall movement of the slide 3.

[0023] Working principle: First, Figure 1 As shown, the elastic insert 4 is in the initial state, at which time the tail end of the elastic insert 4 contacts the front end of the elastic insert connecting rod 6, and the push rod 601 on the elastic insert connecting rod 6 is located inside the push groove 302 as a whole; then, under the action of the elastic insert control block 8 inside the inclined pressure block 9, the slide 3 is pushed forward, as shown in FIG. Figure 2As shown, the terminal foot forming fixture 2 at the front end of the elastic insert 4 captures the product terminal on the front mold strip, and continues to move forward until the front end of the ejector rod 501 in the safety protection device 5 contacts the stopper 1. At this time, the distance between the slide 3 at the position of the safety protection device 5 and the stopper 1 is the distance that the ejector rod 501 extends to the outside, and the distance value is 0.2mm; then push the slide 3 to continue moving forward, as shown in FIG. Figure 3 As shown, the push rod 501 interacts with the stopper 1, thereby pushing the elastic insert connecting rod 6 to move toward the tail end of the slide seat 3 in the moving groove 301 through the safety protection device 5, so that the tail end of the push rod 601 moves to the outside of the push groove 302. At this time, the elastic insert 4 is separated from the elastic insert connecting rod 6, and the elastic insert 4 rebounds under its own elasticity, so that the terminal foot molding fixture 2 at its front end is received into the slide seat 3, entering the mold closing state, and performing the injection molding operation; finally, when the mold is opened, as shown in FIG. Figure 1 As shown, the top end of the inclined guide column 7 is pushed to move the slide seat 3 backward, and the elastic insert connecting rod 6 is pushed through the elastic insert control block 8 inside the inclined pressure block 9 to eject the terminal foot forming fixture 2 at the front end of the elastic insert 4 and return to the initial state.
