It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The main feature of this utility model is that the nose pads and the eyeglass frame are cast as one piece. Since the existing nose pads are set at an angle on the eyeglass frame, they cannot be demolded smoothly in one go according to the conventional model. Therefore, it is necessary to improve the mold structure to achieve one-time molding of the frame and nose pads, and to make them easy to separate after molding.

[0029] The specific structure is shown below, such as Figures 1 to 10 The illustrated eyeglass frame manufacturing mold includes an upper mold base 1 and a lower mold base 2. An upper mold body 11 and an upper mold mounting plate 12 are provided on the upper mold base 1. An upper mold cavity 100 is provided in the upper mold body 11, and an upper mold 101 for eyeglass frames is provided in the upper mold cavity 100. The lower mold base 2 includes a lower mold body 21, a lower mold fixing plate 22 and an ejector pin fixing plate 23. A lower mold mounting cavity 200 is provided in the lower mold body 21.

[0030] like Figure 1 , Figure 2 As shown, a spring 24 is provided between the lower mold fixing plate 22 and the lower mold body 21, and a spring 25 is provided between the ejector pin fixing plate 23 and the lower mold fixing plate 22.

[0031] A spring 24 is arranged between the lower mold fixed plate 22 and the lower mold body 21. After the glasses frame is formed, when the upper mold body 3 and the lower mold body 21 are separated, the spring 24 separates the lower mold body 21 and the lower mold fixed plate 22 due to the elastic effect, so that the glasses frame can be initially demolded. A ejector pin fixed plate 23 is arranged on the lower mold base 2, and an ejector pin is arranged on the ejector pin fixed plate 23. Ejector pin through holes are arranged on the lower mold fixed plate 22 and the lower mold body 21, and the ejector pin is arranged in the ejector pin through holes. In this way, after the glasses frame is formed, when the glasses frame needs to be demolded from the lens lower mold 11, the handle part of the glasses frame can be upwardly pushed by the ejector pin, so that the glasses frame can be secondarily demolded, and the demolding efficiency is improved. A spring 25 is arranged between the ejector pin fixed plate 23 and the lower mold fixed plate 22. After demolding is completed, when the push rod is returned, the ejector pin fixed plate 23 is returned to the original position due to the elastic effect of the spring 25.
