[0023] like Figures 1 to 6 As shown, a movable slider head structure for a mold with anti-collision clearance includes a lower template. A lower groove is formed on the upper surface of the lower template, and a lower mold core 1 is installed in the lower groove. An inner cavity 2 for forming the product body 8 is provided on the upper surface of the lower mold core 1. A sliding groove 3 is formed on one side of the inner cavity 2 on the upper surface of the lower mold core 1. A placement groove 4 communicating with the inner cavity 2 is provided on one side of the sliding groove 3. A movable slider head 6 for installation is provided in the sliding groove 3. A metal terminal 9 is installed on the side of the movable slider head 6 facing the inner cavity 2. The metal terminal 9 is fixed in the groove of the movable slider head 6 by an interference fit. The front end of the metal terminal 9 extends into the inner cavity 2, and the rear end is located in the placement groove 4. A part of the metal terminal 9 is located in the inner cavity 2, and the other part of the metal terminal 9 is located in the placement groove 4. A first gap is provided between the side of the movable slider head 6 facing the center of the inner cavity 2 and the side wall of the slide groove 3. Specifically, the first gap is left between the sealing surface of the movable slider head 6 facing the inner cavity and the corresponding sealing surface of the slide groove 3 in the moving direction of the movable slider head 6.

[0024] In the manufacturing process of the product body 8 with metal terminals 9, insert molding process is usually adopted. First, metal terminals 9 are installed on the movable slider head 6 of the mold. After placing the pre-prepared metal terminals 9, injection molding is performed to form a single piece, and the product body 8 with metal terminals 9 can be obtained. Due to the setting of the first gap, when the movable slider head 6 is placed in the slide groove 3, the movable slider head 6 is prevented from colliding with the inner cavity of the mold core, which would cause damage to the inner cavity of the mold core, thus ensuring product quality and improving the yield rate of the product after injection molding. The setting of the first gap avoids direct rigid contact between the movable slider head 6 and the lower mold core 1.

[0025] The width of the first gap ranges from 0.2 to 0.3 mm, preferably 0.2 mm, to improve the yield of the product after injection molding.

[0026] The first gap may contain air, or it may contain an elastic seal, which includes a pressure plate covered with PFA.

[0027] On the other side of the slide groove 3, a driving component is provided on the lower template. The driving component is a hydraulic cylinder 10. The output end of the driving component is connected to a slider seat 5. A shovel base 11 is provided on the slider seat 5. The inclined surface of the shovel base 11 faces the movable slider head 6. A receiving groove is provided on the lower end face of the slider seat 5. A speed reduction component is provided on the lower template to cooperate with the receiving groove. The speed reduction component includes a speed reduction block 7. The speed reduction block 7 is located between the driving component and the side wall of the lower mold core 1. A second gap is provided between the speed reduction block 7 and the side wall of the lower mold core 1.

[0028] When the mold is in the open state, the hydraulic cylinder 10 drives the slider seat 5 to move until the deceleration block 7 stops. The deceleration block 7 blocks the slider seat 5 from moving further and prevents the slider seat 5 from moving too far forward. At this time, there is a second gap between the deceleration block 7 and the lower mold core 1, and the two do not contact each other. The movable slider head 6 is placed into the slide groove 3. There is a 0.2mm gap between the movable slider head 6 and the lower mold core 1. The sealing part of the movable slider head 6 and the lower mold core 1 is not easily damaged. Finally, the mold is closed in place with the shovel base 11.

[0029] The width of the second gap ranges from 0.1 to 0.3 mm, preferably 0.2 mm, to improve the yield of the product after injection molding.

[0030] The speed reduction component may also include a connecting plate, which is disposed between the speed reduction block 7 and the lower mold core 1. Multiple elastic elements are disposed between the connecting plate and the speed reduction block 7. The elastic elements are elastic springs or buffer dampers. The arrangement of the elastic elements facilitates the speed reduction block 7 and the lower mold core 1 to maintain a certain gap, thereby helping to ensure the stability of the movement of the slider seat 5.

[0031] The deceleration block 7 has multiple sliding holes on one side facing the side wall of the lower mold core 1. A sliding rod that is fixedly connected to the connecting plate is slidably connected in the sliding hole. The elastic element is located between the end of the sliding rod and the bottom of the sliding hole. The elastic element is set in the sliding hole. The setting of the sliding rod and the sliding hole helps to prevent the connecting plate from shifting, ensuring a certain degree of accuracy and stability. The setting of the elastic element helps to maintain a certain gap between the deceleration block 7 and the lower mold core 1, and also facilitates buffering, helping to ensure the stability of the movement of the slider seat 5.

[0032] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
