[0032] Embodiment 1

[0033] This embodiment discloses an injection mold structure for manufacturing a handlebar. Referring to Figures 1 to 4 , it includes an upper template 1, on which an upper die core 2 is fixed. The upper die core 2 is machined with a cavity 3 and a tilt column 4. The cavity 3 is used to form the top shape of the handlebar, and the tilt column 4 is used to cooperate with the tilt hole 8 on the slide block 7 to realize the opening and closing of the mold. The bottom of the upper die core 2 is assembled with a lower die core 5, and the lower die core 5 is machined with a plurality of guide holes 13, which match the guide columns 14 at the bottom of the upper die core 2 to ensure that the upper die core 2 and the lower die core 5 can be accurately aligned. Inside the lower die core 5, four equally spaced handlebar mold bases 6 are arranged, and the shapes of these mold bases match the shape of the handlebar and are used to form the main body part of the handlebar.

[0034] During the injection molding process, the molten plastic is injected into the mold through the pouring gate 17, filling the cavity 3 and the handlebar mold bases 6, and after cooling, a handlebar product is formed. At the same time, an ejecting structure 15 is arranged between the lower die core 5 and the lower template 10. The ejecting structure 15 includes an ejector plate 151 arranged between the lower template 10 and the lower die core 5. A plurality of ejector pins 152 are fixed on the ejector plate 151, and the lower die core 5 is machined with ejector pin holes 153 that match the ejector pins 152, so that the ejector pins 152 can penetrate the ejector pin holes 153 and eject the molded product. In order to further control the movement of the ejector pins 152, a telescopic structure 16 is also arranged between the ejector plate 151 and the lower template 10. The telescopic structure 16 includes an oil cylinder 161 fixed on the lower template 10, and the output shaft of the oil cylinder 161 is fixedly connected to the ejector plate 151. By controlling the telescopic movement of the oil cylinder 161, the movement of the ejector pins 152 can be accurately controlled to realize the stable ejection of the product.

[0035] The implementation principle of Embodiment 1 is as follows: Under the action of an injection molding machine, the molten plastic enters the mold through the pouring gate 17, flows through the pouring channel, and then fills into the cavity 3 and the handlebar mold base 6. Under the action of the cooling system 9, the plastic gradually solidifies and forms. When the product is completely cooled, the ejection structure 15 ejects the product from the mold, completing the entire injection molding process.

Tilt holes 8 matching the tilt posts 4 are machined on these sliders 7, enabling the sliders 7 to perform opening and closing movements under the guidance of the tilt posts 4. A guide rail 11 is installed at the bottom of the slider 7, and the slider 7 is connected to the guide rail 11 through a slide rail to ensure the stable movement of the slider 7. In addition, a locking structure 12 is provided on the slider 7, which includes a limit hole 121 opened in the slider 7 for inserting a limit rod 122. When the limit rod 122 is inserted into the limit hole 121, the slider 7 and the lower mold core 5 will be locked together to ensure the stability of the mold during the injection molding process.

[0038] Embodiment 3

[0039] Referring to Figure 3 This embodiment is different from Embodiment 2 in that a cooling system 9 is provided in the lower mold core 5. The cooling system 9 includes a plurality of cooling channels 91, and the ends of these channels are connected to cooling pipes 92 for circulating coolant. An inlet pipe 93 is also provided on the cooling pipe 92, which is used to connect to a liquid supply device to ensure the continuous supply of coolant. During the injection molding process, the coolant enters the cooling pipe 92 through the inlet pipe 93, then flows through the cooling channels 91 to continuously cool the mold base, ensuring the rapid forming and high quality of the product.
