Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a slider protection pin and an injection mold. Background Technology

[0002] As a core component in injection molds that ensures the safe movement of the slider and prevents molding defects, the slider protection pin plays a crucial role in protecting the slider from damage and ensuring product quality during ejection. However, existing slider protection pins generally adopt a traditional ejector pin structure, which requires complete disassembly of the rear ejector plate and base plate during each mold trial adjustment or maintenance. This results in a complex and time-consuming disassembly and assembly process, high maintenance costs, and frequent disassembly, which accelerates mold wear, ultimately leading to a dual dilemma of reduced production efficiency and soaring overall costs. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a slider protection pin, which has the advantage of being able to quickly replace the slider protection pin.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] The first aspect of this utility model provides a slider protection pin, which includes: a protection pin body, one end of the protection pin body is provided with a first connecting part, and the protection pin body is detachably connected to a push pin plate through the first connecting part; the other end of the protection pin body is provided with a second connecting part.

[0006] Compared with the prior art, this application achieves a detachable connection with the ejector plate by setting a first connecting part on the protective pin body, which solves the limitation that the traditional slider protective pin requires complete disassembly of the ejector plate and base plate for replacement, effectively simplifies the disassembly and assembly process of the protective pin body and improves maintenance efficiency.

[0007] As a preferred embodiment of this utility model, the first connecting part is a threaded hole.

[0008] By adopting the above solution, the first connecting part is designed as a threaded hole. The connection stability between the protective pin body and the ejector plate is enhanced by utilizing the self-locking characteristic of the thread. This avoids the defect of easy loosening of the traditional structure of the slider protective pin under high injection pressure, while retaining the advantage of quick disassembly and assembly of the slider protective pin, thus taking into account both structural reliability and maintenance convenience.

[0009] As a preferred embodiment of this utility model, the protective pin body is detachably connected to the ejector plate by a fixing screw, and the fixing screw passes through the ejector plate and is threadedly connected to the first connecting part.

[0010] By adopting the above solution, the sliding protection pin and the ejector plate are detachably connected through the cooperation of the fixing screw and the threaded hole. This not only ensures the connection strength between the sliding protection pin and the ejector plate, but also allows maintenance personnel to replace the sliding protection pin by simply operating the screw. Compared with the traditional method of disassembling the entire ejector plate and base plate, this effectively improves maintenance efficiency.

[0011] As a preferred embodiment of this utility model, the top wall of the ejector plate is provided with an installation groove, and one end of the protective pin body having the first connecting part is located in the installation groove; the bottom wall of the ejector plate is provided with a receiving groove, the fixing screw is located in the receiving groove, and the fixing screw passes through the ejector plate and is threadedly connected to the first connecting part.

[0012] By adopting the above solution, the mounting groove can provide precise positioning for the protective pin body, reduce the time required for positioning the protective pin body during installation, and prevent displacement caused by vibration during injection molding, thereby improving the accuracy of the molded product. The receiving groove can provide space for the fixing screw, optimize the internal space layout of the mold, and make the structure more compact.

[0013] In a preferred embodiment of this utility model, the position of the mounting groove corresponds to the position of the receiving groove.

[0014] The above-mentioned design, with the mounting slot and the receiving slot positioned in a corresponding manner, ensures that the fixing screw can pass through the ejector plate and connect to the threaded hole in a straight line, avoiding screw stripping or connection failure due to positional deviation and improving the assembly success rate.

[0015] As a preferred embodiment of this utility model, the size and shape of the mounting groove correspond to the size and shape of the cross-section of the protective pin body.

[0016] By adopting the above solution, the size and shape of the mounting groove match the cross-section of the protective pin body, achieving precise positioning and preventing the protective pin from tilting or shaking under high injection pressure. This reduces the risk of slider damage caused by protective pin offset and extends the service life of the mold.

[0017] As a preferred embodiment of this utility model, the second connecting part is a threaded hole.

[0018] The above-mentioned solution uses a threaded hole for the second connection part, which provides a standardized interface for the connection of the protective pin with other mold components (such as push rods, ejector blocks, etc.), enhances the scalability of the structure, facilitates quick adaptation to different mold requirements, and improves the versatility of the solution. Secondly, during the disassembly of the protective pin body, the second connection part can be used in conjunction with other threaded parts to quickly remove the protective pin body, effectively improving the disassembly efficiency of the protective pin body.

[0019] The second aspect of this utility model provides an injection mold that includes the aforementioned slider protection pin, which passes through the moving template.

[0020] The aforementioned slider protection pin has the following advantages: by providing a first connecting part and a second connecting part at both ends of the protection pin body, the protection pin body can be detachably mounted on the ejector plate through the cooperation of the first connecting part and the fixing screw, effectively improving the disassembly and assembly efficiency of the protection pin body; when disassembling the protection pin body, other threaded parts can be used to cooperate with the second connecting part to achieve quick removal of the protection pin body, effectively improving the disassembly efficiency of the protection pin body.

[0029] This utility model proposes a slider protection pin and an injection mold.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2 This utility model provides a slider protection pin in its first aspect, comprising: a protection pin body 1, with a first connecting portion 2 at one end of the protection pin body 1, and the protection pin body 1 being detachably connected to an ejector plate 3 via the first connecting portion 2; and a second connecting portion 4 at the other end of the protection pin body 1. In this embodiment, both the first connecting portion 2 and the second connecting portion 4 are threaded holes. The first connecting portion 2 on the protection pin body 1 enables a detachable connection with the ejector plate 3, overcoming the limitation of traditional slider protection pins requiring complete disassembly of the ejector plate 3 and base plate for replacement. This effectively simplifies the disassembly and assembly process of the protection pin body 1 and improves maintenance efficiency. Designing the first connecting portion 2 as a threaded hole enhances the connection stability between the protection pin body 1 and the ejector plate 3 by utilizing the self-locking characteristic of the thread, avoiding the defect of easy loosening under high injection pressure in traditional slider protection pin structures, while retaining the advantage of quick disassembly and assembly of slider protection pins, thus balancing structural reliability and maintenance convenience. The second connecting part 4 is designed as a threaded hole, which provides a standardized interface for the connection of the protective pin with other mold components (such as push rods, ejector blocks, etc.), enhances the scalability of the structure, facilitates quick adaptation to different mold requirements, and improves the versatility of the solution. Secondly, during the disassembly of the protective pin body 1, the second connecting part 4 can be used in conjunction with other threaded parts to quickly remove the protective pin body 1, effectively improving the disassembly efficiency of the protective pin body 1.

[0032] Reference Figure 1In one embodiment, the protective pin body 1 is detachably connected to the ejector plate 3 via a fixing screw 5. The fixing screw 5 passes through the ejector plate 3 and is threadedly connected to the first connecting part 2. The detachable connection between the slider protective pin and the ejector plate 3 is achieved through the cooperation of the fixing screw 5 and the threaded hole. This ensures the connection strength between the slider protective pin and the ejector plate 3, and allows maintenance personnel to replace the slider protective pin simply by operating the screw. Compared with the traditional method of disassembling the entire ejector plate 3 and the base plate, this effectively improves maintenance efficiency.

[0033] Referring to Figure 2, in one embodiment, to further optimize the internal space layout of the mold and make the structure more compact, an installation groove 6 is provided on the top wall of the ejector plate 3, and one end of the protective pin body 1 with the first connecting part 2 is located in the installation groove 6; a receiving groove 7 is provided on the bottom wall of the ejector plate 3, and a fixing screw 5 is located in the receiving groove 7. The fixing screw 5 passes through the ejector plate 3 and is threadedly connected to the first connecting part 2, and the position of the installation groove 6 corresponds to the position of the receiving groove 7. The size and shape of the installation groove 6 correspond to the size and shape of the cross-section of the protective pin body 1. The installation groove 6 can provide precise positioning for the protective pin body 1, reduce the time required for positioning the protective pin body 1 during installation, and avoid displacement caused by vibration during injection molding, thus improving the accuracy of the molded product; the receiving groove 7 can provide space for the fixing screw 5, optimize the internal space layout of the mold, and make the structure more compact. The corresponding design of the positions of the installation groove 6 and the receiving groove 7 ensures that the fixing screw 5 can pass through the ejector plate 3 in a straight line and connect to the threaded hole, avoiding screw stripping or connection failure due to positional deviation, and improving the assembly success rate. The size and shape of the mounting groove 6 match the cross-section of the protective pin body 1, achieving precise positioning and preventing the protective pin from tilting or shaking under high injection pressure. This reduces the risk of damage to the slider 9 caused by protective pin offset and extends the service life of the mold.

[0034] By providing a first connecting part 2 and a second connecting part 4 at both ends of the protective needle body 1, the protective needle body 1 can be detachably mounted on the ejector plate 3 through the cooperation of the first connecting part 2 and the fixing screw 5, which effectively improves the disassembly and assembly efficiency of the protective needle body 1. When disassembling the protective needle body 1, other threaded parts can be used to cooperate with the second connecting part 4 to realize the quick removal of the protective needle body 1, which effectively improves the disassembly efficiency of the protective needle body 1.
