In this embodiment, four springs are provided and evenly distributed between the mold B plate 2 and the mold C plate 4, so that the force between the mold B plate 2 and the mold C plate 4 is stable.
[0026] In one embodiment, if Figure 1-Figure 9 As shown, a fixing portion 61 is radially protruded from the bottom of the forming insert pin 6, and the sliding member 8 includes a sliding A plate 81 and a sliding B plate 82. The fixing portion 61 is arranged between the sliding A plate 81 and the sliding B plate 82, and the sliding A plate 81 is fixedly connected to the sliding B plate 82. The fixing portion 61 cooperates with the sliding A plate 81 and the sliding B plate 82 to realize the fixed connection between the forming insert pin 6 and the sliding member 8, and the clamping plate type fixing structure can make the forming insert pin 6 and the sliding member 8 reliably connected.
[0027] In the above embodiment, if Figure 1-Figure 9As shown, the sliding plate A 81 and the sliding plate B 82 are fastened by screws.
[0028] In one embodiment, if Figure 1-Figure 9 As shown, the lower surface of the sliding A plate 81 is concavely provided with a limiting groove 811 that cooperates with the fixing part 61, and the fixing part 61 is a semicircular columnar structure. Specifically, the sliding A plate 81 is provided with a through hole that allows the forming insert 6 to pass through; during assembly, the forming insert 6 is passed through the through hole, so that the fixing part 61 is placed in the limiting groove 811, and the semicircular columnar structure is used to fix and stop the forming insert 6. The fixing part 61 is limited in the limiting groove 811 by installing the sliding B plate 82 on the sliding A plate 81.
[0029] In one embodiment, if Figure 1-Figure 9 As shown, the fixing member 7 includes a fixing plate A 71 and a fixing plate B 72. The surface of the fixing plate B 72 is provided with a groove 711 that matches the sliding member 8. The fixing plate A 71 covers the fixing plate B 72. The fixing plate A 71 and the fixing plate B 72 form a channel for guiding the movement of the sliding member 8, which simplifies the assembly steps. Among them, the fixing plate A 71 is provided with a through hole that allows the forming pin 6 to move and satisfies the movement of the forming pin 6.
[0030] In the above embodiment, if Figure 1-Figure 9 As shown, Figure 1-Figure 9 As shown, the fixed A plate 71 and the fixed B plate 72 are fastened by screws.

When the mold is opened, the bottom position of the forming pin 6 is kept at the same height as the mold C plate 4. Therefore, guided by the matching hole 31, the mold C plate 4 drives the forming pin 6 to move downward, and at the same time, the forming pin 6 moves horizontally along the Y axis with the sliding piece 8. When the characteristic part of the forming pin 6 is separated from the product, the mold B plate 2 is separated from the mold A plate 1 to complete the mold opening. When the mold is closed, the mold B plate 2 contacts the mold A plate 1 first; after contact, the mold B plate 2 and the mold A plate remain stationary; the mold C plate 4 continues to move toward the mold B plate 2, and due to the oblique fit between the forming pin 6 and the matching hole 31, the characteristic part of the forming pin 6 protrudes and penetrates into the product cavity; in this process, the forming pin 6 will move horizontally along the Y axis with the sliding piece 8. Until the mold C plate 4 contacts the mold B plate 2. Among them, the guide rod 92 connects the two guide sleeves 91, guides the movement of the mold A plate 1, the mold B plate 2 and the mold C plate 4 along the Z axis, and also plays a positioning role to ensure the relative position relationship of the mold A plate 1, the mold B plate 2 and the mold C plate 4.
