[0019] Compared to traditional molds that use a vertical cylindrical extraction method, which is difficult to adapt to complex structures with top clips and can easily lead to demolding obstruction or product damage, this utility model mold uses an inclined guide post mechanism to guide the upper mold core to move along a horizontal angle, accurately achieving demolding of lateral features. Simultaneously, it utilizes the cooperation of a through-hole insert and an ejector pin, where the through-hole insert and ejector pin abut against each other within the mold cavity. Combined with an optimized design where the ejector pin area is larger than the through-hole insert, this ensures that during molding, the molten plastic flows through the abutment between the through-hole insert and the ejector pin, forming a shaped product on the ejector pin. This allows the ejector pin to eject the shaped product. Notably, the through-hole insert is located in the middle of the ejector pin, ensuring uniform force during upward ejection of the shaped product. Furthermore, at least two through-hole inserts are used, located on both sides of the elastic bending arm, ensuring uniform force on the elastic bending arm during ejection. Utilizing its deformable characteristics, the insert smoothly detaches from the molding part, improving demolding efficiency and product integrity, and enhancing the mold's adaptability to complex kettle rack structures.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0036] Please refer to Figure 1-13 ;

[0037] like Figure 2 As shown, the molded product manufactured by this utility model includes an elastic bending arm 1, a main body 2 and a top buckle 3. The main body 2 has three holes. There are two elastic bending arms 1. The two elastic bending arms 1 are integrally formed with the main body 2. The top buckle 3 is integrally formed with the main body 2.

[0038] This embodiment discloses an injection mold for a bicycle water bottle holder, including: an upper mold base 4, on which an upper mold core 5 and an inclined guide post mechanism are provided; a lower mold base 6, in which a lower mold core 7 and an ejection mechanism 8 are installed; the lower mold core 7 includes a fixing part 71 and a forming part 72, the forming part 72 is an irregularly horizontally placed cylindrical structure, the fixing part 71 is used to keep the position fixed with the lower mold base 6, the two sections of the forming part 72 are symmetrical, and both sections of the forming part 72 are provided with flow channels 9, the inner wall of the upper mold core 5 is provided with a cavity 10 adapted to the flow channel 9, the lower mold core 7 is provided with several reserved slots, the through insert 11 of the upper mold base 4 abuts against the ejector pin 81 of the ejection mechanism 8 and is located in the flow channel 9, the area of ​​the through insert 11 of the upper mold base 4 is smaller than the area of ​​the ejector pin 81 of the ejection mechanism 8.

[0039] Specifically, in use, the injection mold for this bicycle water bottle cage first closes the upper mold base 4 and the lower mold base 6, forming a closed mold cavity with the upper mold core 5 and the lower mold core 7. The runner 9 inside the mold cavity matches the cavity 10 of the upper mold core 5 to form the structure of the water bottle cage. Then, molten plastic is injected into the mold cavity through the runner 9, filling the runner 9 and the cavity 10. After the product is formed, the mold opens, and the inclined guide post mechanism guides the upper mold core 5 to move along a horizontal angle, completing the demolding of the lateral features of the product. At this time, the elastic bending arm 1 in the product is fitted onto the forming part of the lower mold core 7. At 72, because the through insert 11 of the upper mold base 4 abuts against the ejector pin 81 of the ejector mechanism 8 and is located within the flow channel 9, the area of ​​the through insert 11 of the upper mold base 4 is smaller than the area of ​​the ejector pin 81 of the ejector mechanism 8, causing the ejector pin 81 after molding to abut against the product. At this time, when the ejector pin 81 pushes upward, the product water bottle holder is forced to move upward, driving the elastic bending arm 1 to move upward and separate from the molding part 72. Utilizing the deformable characteristic of the elastic bending arm 1, the molded product water bottle holder is pushed out from bottom to top, ensuring that the product completely leaves the mold; compared with the traditional mold... The vertical cylindrical 112 body extraction method is difficult to adapt to complex structures with top clips, easily leading to demolding obstruction or product damage. This mold uses an inclined guide post mechanism to guide the upper mold core 5 to move along a horizontal angle, accurately achieving demolding of lateral features. At the same time, the through insert 11 and the ejector pin 81 cooperate, that is, the through insert 11 and the ejector pin 81 abut against each other, and the abutment point is located inside the mold cavity. Combined with the optimized design that the area of ​​the ejector pin 81 is larger than that of the through insert 11, it is ensured that during the molding process, when the molten plastic flows through the abutment point of the through insert 11 and the ejector pin 81, A molded product is formed on the ejector pin 81, so that the ejector pin 81 can eject the molded product. It is worth noting that the through insert 11 is located in the middle of the ejector pin 81, so that the ejector pin 81 is subjected to uniform force when ejecting the molded product upward. In addition, there are at least two through inserts 11, which are located on both sides of the elastic bending arm 1 to ensure that the elastic bending arm 1 is subjected to uniform force during the ejection process. With its deformable characteristics, it can smoothly detach from the molding part 72, which not only improves the demolding efficiency and product integrity, but also enhances the mold's adaptability to complex kettle rack structures.

[0040] Furthermore, the through insert 11 includes a straight groove post 111 and a cylindrical post 112. Both the straight groove post 111 and the cylindrical post 112 are connected to the upper mold base 4 and move with the movement of the upper mold base 4. The ejector pin 81 of the ejector mechanism 8 includes a straight groove pin 811 and a cylindrical pin 812. The flow channel 9 of the lower mold core 7 is provided with a straight groove protrusion 12 and a cylindrical protrusion 13. The straight groove protrusion 12 has a straight groove 14, and the cylindrical protrusion 13 has a circular groove 15. The straight groove 14 and the circular groove 15 are respectively connected to the lower mold core 7. The reserved slots are connected. In the initial state, the straight groove needle 811 passes through the straight groove 14 and is flush with the upper surface of the straight groove protrusion 12, and the round needle 812 passes through the round groove 15 and is flush with the upper surface of the round groove 15. On the one hand, the straight groove protrusion 12 and the round protrusion 13 facilitate the filling of the molded product, namely hole one and hole two. On the other hand, the straight groove 14 of the straight groove protrusion 12 and the round groove 15 of the round protrusion 13 prevent the straight groove needle 811 and the round needle 812 in the ejector pin 81 from swinging and affecting the quality of the molded product.

[0041] In this embodiment, the upper mold base 4 also includes a heart-shaped column insert 16, which passes through the upper mold core 5 and is connected to the upper mold base 4. It moves with the movement of the upper mold base 4. One end of the heart-shaped column insert 16 facing the lower mold core 7 is located in the flow channel 9 and maintains a gap with the lower mold core 7. A warning sign is provided at this end of the heart-shaped column insert 16, thereby saving the engraving process after the molded product is formed, saving the process and increasing work efficiency.

[0042] In this embodiment, steps 17 are provided on both sides of the groove of the lower mold base 6, and side pressure columns 18 are provided on the steps 17. The side pressure columns 18 are detachably connected to the steps 17. The way the side pressure columns 18 are connected to the steps 17 is not unique. In this embodiment, screws are used as an example. Side sliding grooves 51 are provided on both sides of the upper mold core 5. The side sliding grooves 51 are slidably connected to the side pressure columns. The side pressure columns 18 are used to limit the position of the upper mold core 5 and prevent the upper mold core 5 from being driven to move upward, so that the upper mold core 5 can achieve stable horizontal movement.

[0043] In this embodiment, the inclined guide post mechanism includes an inclined guide post 19. An adjustment hole 20 is provided on the lower mold base 6, and a fixing hole is provided on the upper mold base 4. The inclined guide post 19 moves with the movement of the upper mold base 4. One end of the inclined guide post 19 is fixedly connected to the upper mold base 4 through the fixing hole, and the other end of the inclined guide post 19 moves through the upper mold core 5 and the wall of the adjustment hole 20.

[0044] In this embodiment, the lower mold base 6 is provided with several square grooves 22, and a stabilizing block 23 is provided in each square groove 22. The stabilizing block 23 is connected to the lower mold base 6. The stabilizing block 23 has a clearance hole 24 for avoiding the inclined guide post 19 and a stabilizing hole 25. The lower mold base 6 is provided with a retaining member 26. The stabilizing hole 25 is used to calibrate the position of the retaining member 26. The stabilizing block 23 and the upper mold base 4 are used to fix the retaining member 26. The retaining member 26 is used to fix the position of the upper mold core 5. Further, the retaining member includes a stabilizing part 261, a stepped part 262 and an inclined wall part 263. The stabilizing part 261 is engaged with the stabilizing hole 25. The stepped part 262 is engaged with the inner cavity of the upper mold base 4. The inclined wall part 263 is adapted to the side wall of the upper mold core 5. The inclined wall part 263 has an inclined groove, and a soft pad 27 is fixedly provided on the groove wall.

[0045] Specifically, during the use of the bicycle water bottle cage injection mold in this embodiment, during transportation, the stabilizing part 261 of the fixing component is first engaged with the stabilizing hole 25 on the stabilizing block 23 of the lower mold base 6 to ensure accurate positioning of the fixing component. The upper mold base 4 is then engaged with the stepped part 262 of the fixing component. At this time, the soft pad 27 of the inclined wall part 263 of the fixing component is in close contact with the side wall of the upper mold core 5. The cushioning effect of the soft pad 27 protects the upper mold core 5 and prevents the upper mold core 5 from shifting due to vibration or collision during transportation, thereby ensuring the stability of the upper mold core 5. When using the mold, the fixing component is removed, and the engagement between the stabilizing part 261 and the stabilizing hole 25, and between the stepped part 262 and the inner cavity of the upper mold base 4 is released. In the connected state, the upper mold base 4 and the lower mold base 6 close together. The inclined guide post 19 passes through the clearance hole 24 of the stabilizing block 23, and the upper mold core 5 and the lower mold core 7 form a closed mold cavity, and the injection molding process continues. By setting the stabilizing block 23 and the fixing parts in the lower mold base 6, the stability of the mold during transportation and use is improved. The stabilizing hole 25 of the stabilizing block 23 and the stabilizing part 261 of the fixing parts are precisely engaged. Combined with the engagement design of the stepped part 262 and the inner cavity of the upper mold base 4, the position of the upper mold core 5 is effectively fixed to prevent displacement or damage during transportation. The inclined wall part 263 is adapted to the side wall of the upper mold core 5 and is equipped with a soft pad 27, which further protects the upper mold core 5 through the buffering effect and improves the durability of the mold.

[0046] Furthermore, there are four square slots, which are located on both sides of the lower mold core 7. A sliding groove is provided between two square slots, and a sliding block 28 is provided in the sliding groove. The length direction of the sliding block 28 is consistent with the moving direction of the upper mold core 5. The upper mold core 5 is provided with a through groove, and the sliding block 28 is slidably connected to the groove wall of the through groove, thereby realizing the stable movement of the upper mold core 5 in the horizontal direction.

[0047] In this embodiment, the upper mold core 5 is provided with a cooling pipe 29, which includes an inlet pipe and an outlet pipe. The inlet pipe and the outlet pipe are connected through a circulation pipe to achieve cooling and rapid molding.
