[0002] Optical glass is a glass material used to manufacture lenses, prisms, mirrors, windows, etc. in optical instruments or mechanical systems. The molding technology of optical glass lenses is a high-precision optical component processing technology. It involves placing softened glass into a high-precision mold and molding it directly into an optical part that meets the requirements of use under heating, pressure and oxygen-free conditions in one go.

[0003] The conventional method for temperature measurement in molding machines is thermocouples. However, thermocouples have only one or a limited number of measurement points, making it difficult to accurately reflect the temperature process characteristics of the core area. The measurement accuracy and response are also slow, resulting in inaccurate temperature monitoring and control in molding machines. Utility Model Content

[0004] Therefore, it is necessary to provide a temperature monitoring device and a molding machine to solve the technical problem of inaccurate temperature monitoring in existing molding machines.

[0005] Therefore, according to one aspect of this application, a temperature monitoring device is provided for monitoring the operating temperature of a molding machine, the molding machine including an upper mold and a lower mold, the temperature monitoring device including two temperature measuring optical fibers and an information processing device communicating with the two temperature measuring optical fibers, the two temperature measuring optical fibers being wound around the outer side of the upper mold and the outer side of the lower mold respectively, the temperature measuring optical fibers being distributed with multiple temperature measuring segments along their length direction, and the information processing device being used to monitor the temperature measurement data of the multiple temperature measuring segments.

[0006] Optionally, both the upper and lower molds are cylindrical structures, with two temperature-measuring optical fibers spirally wound around the outer surfaces of the upper and lower molds, respectively.

[0007] Optionally, the outer sides of the upper mold and the lower mold are respectively provided with grooves for adapting the temperature measuring fiber, and the temperature measuring fiber is embedded in the groove.

[0008] Optionally, the temperature monitoring device may also include a display device electrically connected to the information processing device.

[0009] Alternatively, the information processing device may be integrated into the display device.

[0010] According to another aspect of this application, a molding machine is provided, which includes an upper mounting base, a lower mounting base, a linear drive mechanism, an upper mold, a lower mold, a heating device, and a temperature monitoring device as described above. The upper mounting base is located above the lower mounting base. The linear drive mechanism is used to drive the upper mounting base to move in a vertical direction. The upper mold is disposed on the bottom surface of the upper mounting base, and the lower mold is disposed on the top surface of the lower mounting base and corresponds to the upper mold. The heating device is used to heat the lower mold. The bottom surface of the upper mold is provided with an upper mold cavity, and the top surface of the lower mold is provided with a lower mold cavity corresponding to the upper mold cavity. Two temperature-measuring optical fibers of the temperature monitoring device are respectively wound around the outer side of the upper mold and the outer side of the lower mold.

[0011] Optionally, the temperature-sensing optical fiber wound around the outer side of the upper mold is also laid on the bottom surface of the upper mounting base, and the temperature-sensing optical fiber wound around the outer side of the lower mold is also laid on the top surface of the lower mounting base.

[0012] Optionally, the bottom surface of the upper mounting base and the top surface of the lower mounting base are respectively provided with grooves for adapting the temperature measuring fiber, and the temperature measuring fiber is embedded in the groove.

[0013] The beneficial effects of the temperature monitoring device and molding machine provided in this application are as follows: Compared with the prior art, the molding machine of this application includes an upper mounting base, a lower mounting base, a linear drive mechanism, an upper mold, a lower mold, a heating device, and the temperature monitoring device. The temperature monitoring device includes two temperature-sensing optical fibers and an information processing device that is communicatively connected to the two temperature-sensing optical fibers. The two temperature-sensing optical fibers are respectively wound around the outer side of the upper mold and the outer side of the lower mold. Compared with the traditional thermocouple point structure, the temperature-sensing optical fiber laying structure is more stable and has better contact, making the temperature monitoring of the mold more sensitive and efficient. The temperature-sensing optical fibers are distributed with multiple temperature-sensing segments along their length. The information processing device is used to monitor the temperature measurement data of multiple temperature-sensing segments, realizing distributed continuous temperature measurement and synchronous monitoring. It can relatively stably monitor the temperature dynamic process and temperature distribution status of the heating and cooling process of the molding machine in real time, which is beneficial for observing the process temperature status and system structure stability during the production process of the molding machine.

[0025] In this embodiment, the temperature monitoring device includes two temperature-sensing optical fibers 6 and an information processing device connected to the two temperature-sensing optical fibers 6.

[0027] In one embodiment, see Figure 1 The outer sides of the upper mold 3 and the lower mold 4 are respectively provided with grooves for the temperature measuring fiber 6. The temperature measuring fiber 6 is embedded in the grooves, which improves the installation stability of the temperature measuring fiber 6 and makes it less likely to fall off.

The upper mold 3 is disposed on the bottom surface of the upper mounting base 1, and the lower mold 4 is disposed on the top surface of the lower mounting base 2 and corresponds to the upper mold 3. The heating device 5 is used to heat the lower mold 4. The bottom surface of the upper mold 3 is provided with an upper mold cavity 310, and the top surface of the lower mold 4 is provided with a lower mold cavity 410 corresponding to the upper mold cavity 310. The two temperature measuring optical fibers 6 of the temperature monitoring device are respectively wound around the outer side of the upper mold 3 and the outer side of the lower mold 4.
