Description

Technical Field

[0001] This utility model relates to the technical field of core-pulling molds, specifically to a slider structure with an internally designed inclined core-pulling mechanism. Background Technology

[0002] Angled core pulling refers to the process in which, in order to form side holes, side recesses, or other non-axial features on a product, a directional core is set inside the mold slider at a certain angle to the mold opening and closing direction.

[0003] When the mold opens, the inclined core puller needs to move and extract the core. Conventional extraction methods typically use a hydraulic cylinder to drive the core for inclined extraction. However, in some parts, due to the limited range of the mold slider, a hydraulic cylinder cannot be installed. Therefore, some inclined core pullers rely on the movement of the moving mold to automatically pull the core using an inclined block. For example, the existing technology "Mold Mechanism for Slider Driving Inclined Ejector Reversing Shaft" (Publication No.: CN106808655A) discloses a core pulling structure. An inclined guide post is set on the fixed mold. When the mold opens, the movement of the moving mold causes the core to slide obliquely along the inclined guide post and detach from the product, automatically completing the inclined core pulling process. However, the existing technology still has the following technical problems:

[0004] After the mold is fully opened, the core needs to detach from the inclined guide post in order to facilitate demolding of the molded product. However, in the existing technology, since the core itself is slidably connected to the moving mold, the inertial force of the moving mold can easily cause the core to continue to slip slightly after detaching from the inclined guide post. This results in a slight deviation between the position of the inclined hole on the core and the end position of the inclined guide post. Consequently, during the next mold closing, the inclined guide post cannot be accurately inserted into the inclined hole on the core, making it easy for the inclined guide post to hit the core, causing damage to the core and the equipment, resulting in poor safety and reliability. Utility Model Content

[0005] This utility model provides a slider structure with an internal inclined core-pulling mechanism, which can solve the problem that the existing slider mechanism cannot guarantee that the core will slip after the mold is fully opened, which will cause the inclined guide post to fail to accurately insert into the inclined hole on the core during the next mold closing, resulting in the inclined guide post hitting the core, causing damage to the core and equipment, and poor safety and reliability.

[0006] This application provides the following technical solution: a slider structure with an internal inclined core pulling, including a fixed mold, a moving mold, an inclined pin fixed on the fixed mold, and a main slide block slidably connected to the moving mold;

[0007] The main slide is provided with a core that slides in an inclined direction. The core includes a core-pulling slide, a fixing block and an inclined core-pulling block that are fixedly connected in sequence. The core-pulling slide has an inclined hole and an inclined pin is located in the inclined hole.

[0008] It also includes a core limiting component disposed at the tail of the core-pulling slide. The core limiting component includes a limiting plate fixed on the main slide, a pull stud slidably connected to the limiting plate, and a compression spring sleeved on the pull stud rod. The limiting plate is in the same direction of inclination as the core-pulling slide, and the end of the pull stud away from the compression spring is fixed to the tail of the core-pulling slide.

[0009] Beneficial effects:

[0010] This design ensures precise positioning of the core and the inclined pin, preventing the inclined pin from impacting the core and improving safety and reliability. In this solution, one end of the pull pin is fixed to the core-pulling slide, while the other end is fitted with a compression spring. When the mold is fully opened, the core-pulling slide completely disengages from the inclined pin, and the entire core is gradually pulled closer to the limiting plate by the spring force. Simultaneously, the limiting plate and the core-pulling slide are tilted in the same direction, ensuring the tail end face of the core-pulling slide is in close contact with the limiting plate, achieving precise positioning of the core-pulling slide. During the next mold closing, the inclined hole on the core-pulling slide aligns with the end of the inclined pin, allowing the inclined pin to precisely insert into the inclined hole and guide the entire core. Compared to existing technologies, this design effectively limits the core, preventing the inclined pin from impacting the core during mold closing, ensuring mold safety, and improving safety and reliability.

[0011] Furthermore, a slanted pin locking block is fixed on the moving mold. The slanted pin locking block is used to press the slanted pin against the center of the moving mold. After being pressed, the slanted pin makes contact with the inner side of the slanted hole of the core-pulling slide without any gap.

[0012] Beneficial effects: Due to the high pressure inside the mold during the die casting process, the inclined pin locking block can prevent the core from dislodging, which helps to improve the accuracy of the die-cast product.

[0013] Furthermore, the inclined pin includes an inclined section and a vertical section, and the vertical section of the inclined pin is fixed to the fixed mold.

[0014] Beneficial effects: Setting the beveled pin to a bent shape, and the vertical section of the beveled pin facilitates its installation and removal.

[0015] Furthermore, the vertical section of the inclined pin is fixed to the mold by a vertical screw and a horizontal screw.

[0016] Beneficial effect: By using both vertical and horizontal screws for bidirectional fixation, the positioning stability of the wedge pin can be improved.

[0017] Furthermore, the contact surface between the inclined pin locking block and the inclined pin is an inclined surface, and the inclination direction of the inclined surface is opposite to the inclination direction of the inclined pin.

[0018] Beneficial effects: Since the inclined pin is fixed on the fixed mold with a certain inclination, the contact surface between the inclined pin locking block and the inclined pin is set to be opposite to the inclination direction of the inclined pin. When the mold is closed, the inclined pin locking block gradually presses against the inclined pin to ensure the pressing force. When the mold is opened, the inclined pin will not interfere with the inclined pin locking block, thus protecting the mold and the safety of mold opening.

[0019] Furthermore, a main slider is fixed on the main slide block, and the inclined core puller is slidably connected inside the main slider.

[0020] Beneficial effects: Due to the longer length of the inclined core puller, the main slide block can be used to limit and fix the rod of the inclined core puller, ensuring that the inclined core puller deforms during the die casting process and ensuring the product forming accuracy.

[0021] Furthermore, a slide locking block is also fixed on the fixed mold, which is used to limit the movement of the main slide.

[0022] Beneficial effects: The slide locking block is used to limit the main slide, preventing the main slide from dislodging due to the high pressure inside the mold during the die casting process, which helps to ensure the accuracy of product molding. Attached Figure Description

[0027] Example 1

[0028] like Figure 1 and Figure 2 As shown, a slider structure with an internal inclined core pull includes a fixed mold 7, a moving mold 2 disposed opposite to the fixed mold 7, an inclined pin 15 fixed on the fixed mold 7, a main slide block 10 slidably connected to the moving mold 2, a main slider 11 fixed on the main slide block 10, a core slidably disposed in the main slide block 10 in an inclined direction, and a core limiting member disposed at the tail of the core.

[0029] The core includes a core-pulling slide 14 slidably connected to the main slide 10, a fixing block 13 screwed to the end of the core-pulling slide 14 and slidable relative to the main slide 10, and an inclined core-pulling 12 fixed in the fixing block 13. One end of the inclined core-pulling 12 extending out of the fixing block 13 is slidably connected to the main slide block 11. An inclined hole is provided at the end of the core-pulling slide 14 away from the fixing block 13, and an inclined pin 15 is located in the inclined hole and can slide relative to the inclined hole.

[0030] The core limiting component includes a limiting plate 3 fixed on the main slide 10, a pull stud 4 slidably connected to the limiting plate 3, and a compression spring 5 sleeved on the rod of the pull stud 4. Figure 2 As shown, the limiting plate 3 is L-shaped, with one end fixed to the tail end of the main slide 10, and the other end used to support the rod of the pull pin 4, and cooperates with the tail end of the pull pin 4 to limit the compression spring 5, as shown. Figure 1 As shown, the end of the pull pin 4 away from the compression spring 5 is fixed to the tail of the core-pulling slide 14 by a threaded connection, and the limiting plate 3 is in the same tilt direction as the core-pulling slide 14.

[0031] The inclined pin 15 includes an inclined section and a vertical section. The fixed mold 7 is provided with a horizontal screw hole 6 and a vertical screw hole 8. The vertical section of the inclined pin 15 is bidirectionally fixed to the fixed mold 7 by the horizontally set screw and the vertically set screw, which can improve the positioning stability of the inclined pin 15.

[0032] The fixed mold 7 is also fixed with a slide locking block 9, which is used to limit the main slide 10; to prevent the main slide 10 from dislodging due to the high pressure in the mold during the die casting process, which helps to ensure the accuracy of product molding.

[0033] A slanted pin locking block 1 is also fixed on the moving mold 2. The contact surface between the slanted pin locking block 1 and the slanted pin 15 is an inclined surface, and the inclination direction of the inclined surface is opposite to the inclination direction of the slanted pin 15. The slanted pin locking block 1 is used to press the slanted pin 15 towards the center of the moving mold 2. After being pressed, the slanted pin 15 makes contact with the inner side of the inclined hole of the core-pulling slide block 14 without gap. Since the internal pressure of the mold is high during the die-casting process, the pressing of the slanted pin 15 by the slanted pin locking block 1 can prevent the core position from dislodging, which helps to improve the accuracy of the die-cast product. In addition, the slanted pin 15 is fixed on the fixed mold 7 with a certain inclination. The contact surface between the slanted pin locking block 1 and the slanted pin 15 is set to be opposite to the inclination direction of the slanted pin 15. When the mold is closed, the slanted pin locking block 1 gradually presses against the slanted pin 15 to ensure the pressing force. When the mold is opened, the slanted pin 15 will not interfere with the slanted pin locking block 1, protecting the mold and the safety of the mold opening.

[0034] The usage method of this structure is as follows:

[0035] Figure 1In the mold-closed state, when mold opening and core pulling are required, the moving mold 2 retracts away from the fixed mold 7. The main slide 10, main slide block 11, core-pulling slide 14, angled core pull 12, limiting plate 3, and pull pin 4 all move with the moving mold 2. Due to the guiding effect of the angled pin 15, the core-pulling slide 14 gradually exits from the main slide 10, and the angled core pull 12 also gradually exits from the main slide block 11. When the moving mold 2 moves into position and reaches the fully open state, the core-pulling slide 14 completely disengages from the angled pin 15. At this time, the elastic force of the compression spring 5 causes the core-pulling slide 14 to slide until its tail end is pressed against the limiting plate 3 and then stops, thus limiting the core-pulling slide 14. Then the main slide 10, main slide block 11, core-pulling slide 14, angled core pull 12, limiting the core-pulling slide 14; The slide block 10 will retract away from the center of the moving mold 2 under the action of the hydraulic cylinder. At the same time, the core-pulling slide block 14 and the various parts associated with the limiting plate 3 will also move with the main slide block 10, and the product can be demolded later. When the mold is closed, the hydraulic cylinder will drive the main slide block 10 to reset towards the center of the moving mold 2. Since the limiting plate 3 has already limited the core-pulling slide block 14, after the main slide block 10 is reset, the position of the inclined hole and the inclined pin 15 of the core-pulling slide block 14 has also been accurately positioned. At this time, the moving mold 2 moves towards the fixed mold 7 to close the mold, and the core-pulling slide block 14 will gradually reset along the inclined pin 15 until the mold is completely closed, and the next die casting can begin.
