[0002] The mold core-pulling mechanism is a special mechanism used in mold design, primarily to solve the problem of molds failing to demold properly when products have side overcuts (i.e., side protrusions). The tunnel-slider mechanism achieves the function of side core pulling by setting a tunnel-shaped groove in the mold, allowing the slider to slide within the tunnel.
[0003] Traditional female mold slider solution: The slider base is fixed on the plate behind the female mold plate. When opening the mold, this plate needs to be separated from the female mold plate first and the slider needs to be pulled out. Then the male and female mold plates are separated to complete the mold opening. When opening the mold, the hot runner plate and the female mold plate are separated. If the technician fails to close the mold and inject the glue, it may cause abnormal glue injection through the hot nozzle hole. Utility Model Content
[0004] The purpose of this invention is to provide a hot runner mold master mold tunnel slider mechanism to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot runner mold female mold tunnel slider mechanism, comprising a hot runner plate, a male mold pad, and a slider base.

Guide sleeves are sleeved at both the upper and lower ends of the guide posts.
[0007] Furthermore, the guide posts are vertically inserted through the four opposite corners of the hot runner plate, the female template, the male template, and the male template pad, and the guide sleeves are respectively embedded and installed at the four opposite corners of the female template and the male template.
[0008] Furthermore, the lower end of the slider shovel base is fixedly installed on one end of the mold base, and the bottom end of the slider shovel base adopts an insert-type structure to connect and combine with the mold base.
[0009] Furthermore, the hot runner plate, the female mold plate, the male mold plate, and the male mold pad are arranged in a vertically stacked structure from top to bottom, and the slider base, the female mold slider, the limiting plate, and the guide slider are all located inside the connection between the female mold plate and the male mold plate.
[0010] Furthermore, the upper end of the slider base is provided with an inclined wedge-shaped structure, and the interior of the mother mold slider is provided with a groove channel structure that matches the upper surface structure of the slider base.
[0011] Furthermore, the female mold slider is horizontally slidably inserted into the left and right sides of the female template, and the guide slider and the limiting plate are disposed between the female mold slider and the female template.
[0012] Furthermore, the positioning block adopts an upper and lower splicing structure, and the upper and lower parts of the positioning block are respectively set with a "convex" shape and a "concave" shape, and the upper and lower parts of the positioning block are respectively installed with an embedded structure on the side of the female template and the male template.
[0013] This utility model provides a hot runner mold master mold tunnel slider mechanism, which has the following beneficial effects:
[0014] 1. This utility model adds a male mold pad structure to the bottom of the male mold plate, and vertically fixes the bottom end of the slider base to one end surface of the male mold pad using an insertion structure. The female mold slider, installed inside the bottom side of a section of the female mold plate, is inserted into the upper end of the slider base. Therefore, when mold opening is required, the male mold plate and the male mold pad can be structurally separated first. Since the slider base and the male mold pad are fixedly connected, when the slider base is pulled out and the mold is opened, the male mold pad and the slider base are simultaneously pulled vertically downwards. Then, when separating the female and male mold plates, the separation of the hot runner plate and the female mold plate can be minimized. With the above structural design, the female mold slider inserted into the slider base will not affect the structure of the female mold plate. This minimizes the risk of abnormal glue injection through the hot runner hole due to operator error, ensuring the normal use of structural components and avoiding unnecessary structural maintenance, thus reducing the impact on production efficiency.
[0015] 2. This utility model features positioning blocks that are vertically and horizontally connected on all four sides of the connection between the female and male templates. The upper and lower structures of these four positioning blocks are respectively connected and fixed to the sides of the female and male templates. Combined with the four sets of guide sleeves at the four opposite corners of the female and male templates, stable vertical sliding along the surface of the guide columns is achieved. The use of this structure ensures structural stability when the female and male templates are joined or separated, providing sufficient structural guidance and ensuring the accuracy of the connection. The limiting plate and guide slider structure not only provide structural limitation for the slider base and ensure stability after assembly, but also facilitate the stable extraction of the entire slider base from the connection between the female and male templates, ensuring smooth operation.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figures 1 to 3As shown, a hot runner mold female mold tunnel slider mechanism includes a hot runner plate 1, a male mold pad 4, and a slider base 5. A female mold plate 2 is located at the bottom of the hot runner plate 1, and a male mold plate 3 is located at the bottom of the female mold plate 2. The male mold pad 4 is located at the bottom of the male mold plate 3. The slider base 5 is vertically installed at both ends of the male mold pad 4, and a female mold slider 6 is connected to the top of the slider base 5. The lower end of the slider base 5 is fixedly installed at one end of the male mold pad 4, and the bottom end of the slider base 5 is connected to the male mold pad 4 using an insert-type structure. The hot runner plate 1, female mold plate 2, male mold plate 3, and male mold pad 4 are arranged in a vertically stacked structure from top to bottom. The slider base 5, female mold slider 6, limiting plate 7, and guide slider 8 are all located on the female mold plate 2. Inside the joint of the male template 3, the upper end of the slider base 5 adopts an inclined wedge structure, and the interior of the female template slider 6 is provided with a groove channel structure that matches the upper surface structure of the slider base 5. The female template slider 6 is horizontally slidably inserted into the left and right sides of the female template 2, and the guide slider 8 and the limiting plate 7 are set between the female template slider 6 and the female template 2. When mold opening is required, the male template 3 and the male template pad 4 can be structurally separated first. At the same time, since the slider base 5 and the male template pad 4 are fixedly connected to each other, when the slider base 5 is pulled out and the mold is opened, the male template pad 4 and the slider base 5 are simultaneously pulled out vertically downwards. Then, when separating the female template 2 and the male template 3, the separation of the hot runner plate 1 and the female template 2 can be avoided to the greatest extent.
[0022] like Figures 1 to 3 As shown, a limit plate 7 is provided on the top of the female mold slider 6, and guide sliders 8 are provided on the lower ends of both sides of the female mold slider 6. Positioning blocks 9 are installed at the four side joints of the female mold plate 2 and the male mold plate 3. Guide posts 10 are vertically inserted through the four diagonals of the female mold plate 2, and guide sleeves 11 are sleeved on the upper and lower ends of the guide posts 10. The guide posts 10 are vertically inserted through the four diagonals of the hot runner plate 1, the female mold plate 2, the male mold plate 3, and the male mold pad 4 in sequence. The guide sleeves 11 are respectively embedded and installed at the four diagonals of the female mold plate 2 and the male mold plate 3. The positioning blocks 9 adopt an upper and lower splicing structure, and the upper and lower parts of the positioning blocks 9 adopt a "convex" shaped structure and a "concave" shaped structure, respectively. The "U" shaped structure is designed, and the upper and lower parts of the positioning block 9 are embedded in the sides of the mother template 2 and the male template 3 respectively. The positioning blocks 9 are set on the four side facades at the junction of the mother template 2 and the male template 3. The upper and lower structures of the four sets of positioning blocks 9 are connected and fixed to the sides of the mother template 2 and the male template 3 respectively. With the structural setting of the four sets of guide sleeves 11 at the four opposite corners of the mother template 2 and the male template 3, it can slide stably up and down along the surface of the guide column 10. The use of the above structure can ensure the structural stability of the mother template 2 and the male template 3 when they are connected or separated, and provide sufficient structural guidance.
[0023] In summary, as Figures 1 to 3 As shown, when the hot runner mold mother mold tunnel slider mechanism needs to be opened, firstly, the male mold pad 4 with slider bases 5 vertically fixed at both ends is structurally separated from the male template 3 at its top. Since the left and right slider bases 5 vertically penetrate the male template 3, as the slider bases 5 and the male template 3 are separated, the slider bases 5 will slide along the channel opened inside the male template 3.
[0024] At this time, since the upper end of the slider base 5 is set with an inclined wedge structure, as the slider base 5 is pulled vertically downward, the female mold slider 6 will be pushed to the outside of the female template 2 in the horizontal direction. As the male mold pad 4 connected to the slider base 5 separates from the male template 3, no unnecessary structural interference will be caused to the upper female template 2 during this process.
[0025] Then, using the structure of the limiting plate 7 and the guide slider 8, the female mold slider 6 is pulled out from the lower end of the inside of the female mold plate 2. Then, the guide sleeves 11 set at the four opposite corners of the female mold plate 2 and the male mold plate 3 are used to disassemble the structure along the surface of the guide pillar 10. This can minimize the separation of the hot runner plate 1 and the female mold plate 2 when the mold is opened, and avoid the abnormality of hot nozzle hole injection caused by the technician's operation error of not closing the mold and injecting glue.
[0026] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
