Description

Technical Field

[0001] This application relates to the field of molding machine equipment technology, and in particular to a molding heating structure with integrated temperature monitoring. Background Technology

[0002] Optical glass is a type of glass material used in the manufacture of lenses, prisms, mirrors, windows, etc., for optical instruments or mechanical systems. It has wide applications in consumer electronics, medical devices, and military weaponry. Precision molding technology, with its advantages of high precision, high efficiency, and low cost, has become the primary method for mass production of optical glass components. Precision molding technology uses a molding machine to heat and shape optical glass components. Heating methods include gas flame heating, infrared heating, and resistance wire heating.

[0003] The mold assembly of a molding machine is the core production area, characterized by high temperatures and complex processes. It involves intricate heat exchange with the external environment, necessitating temperature monitoring and control during processing. Conventional temperature monitoring methods include thermocouple measurement and infrared monitoring. Thermocouples require specific design and installation based on the equipment's structure and thermal environment. Their limited, single-point measurement capabilities make them ill-suited to accurately reflect the temperature characteristics of the core area, resulting in low accuracy and slow response. Infrared monitoring, on the other hand, is susceptible to interference from various radiating surfaces, leading to significant data errors. Neither method meets the high precision requirements of optical glass production. Utility Model Content

[0025] Reference Figure 1 as well as Figure 2 A molding heating structure with integrated temperature monitoring includes a lower mold assembly 1 and an upper mold assembly 2 that can be brought close together or moved away from each other, and a temperature measuring component 3. During operation, the lower mold assembly 1 and the upper mold assembly 2 process the material. During this process, the temperature measuring component 3 monitors the temperature of the lower mold assembly 1 and the upper mold assembly 2. Based on the temperature monitoring results, the temperature of the molding heating structure can be easily and instantly adjusted to ensure the quality of the finished product.

[0026] Specifically, the lower mold assembly 1 includes a lower mold base plate 11, on which a lower mold component 12 and a lower heating element 13 are disposed. The lower mold component 12 is fixedly connected to the lower mold base plate 11 and has a lower mold cavity 121 facing the upper mold assembly 2. The lower heating element 13 may specifically be a heating wire, and the lower heating element 13 is spirally diffused along the circumferential direction of the lower mold base plate 11.

[0027] Similarly, the upper mold assembly 2 includes an upper mold base plate 21, on which an upper mold component 22 and an upper heating element 23 are disposed. The upper mold component 22 is fixedly connected to the upper mold base plate 21 and has an upper mold cavity 221 facing the lower mold cavity 121. The upper heating element 23 may specifically be a heating wire. The upper heating element 23 is spirally diffused along the circumferential direction of the upper mold base plate 21, and is connected to a heating lead for providing energy.

[0028] Reference Figure 1 , Figure 2 as well as Figure 3The temperature measuring component 3 includes an external temperature measuring component 31 and an internal temperature measuring component 32. The external temperature measuring component 31 is used to measure the temperature of the outer side of the heating structure, and the internal temperature measuring component 32 is used to measure the temperature of the inner side of the heating structure. The external temperature measuring component 31 includes a lower mold external temperature measuring fiber 311 covering the outer side of the lower mold component 1 and an upper mold external temperature measuring fiber 312 covering the outer side of the upper mold component 2. The structure of the lower mold external temperature measuring fiber 311 is the same as that of the upper mold external temperature measuring fiber 312.

[0029] Taking the external temperature sensing fiber 312 as an example, the external temperature sensing fiber 312 includes an upper mold segment 3121 and an upper substrate segment 3122. The upper mold segment 3121 is spirally arranged along the circumferential direction of the upper mold 22, and the upper substrate segment 3122 is spirally arranged along the circumferential direction of the upper mold substrate 21. In this embodiment, the upper mold segment 3121 has a starting point located on the side of the upper mold cavity 221 near the upper mold substrate 21. The upper mold segment 3121 is wound through the upper mold 22 and then connected to the upper substrate segment 3122. The upper substrate segment 3122 is wound through the upper mold substrate 21 and then connected to the internal temperature sensing component 32. It can be understood that the upper mold segment 3121 and the upper substrate segment 3122 can also be independently arranged temperature sensing fiber segments. To accommodate the installation of the upper mold segment 3121 and the upper substrate segment 3122, the upper mold substrate 21 and the upper mold component 22 are provided with upper mold slots. The upper mold segment 3121 and the upper substrate segment 3122 are fitted into the upper mold slots. Through the upper mold slots and upper substrate slots, the external temperature-sensing fiber optic cable 312 can be quickly fitted and installed. This also increases the contact area between the external temperature-sensing fiber optic cable 312 and the upper mold component 2, thereby enabling stable monitoring of the temperature process and distribution during heating and cooling. This makes temperature monitoring and control fast and controllable, facilitating efficient and accurate temperature acquisition.

[0030] The internal temperature measurement component 32 includes a lower mold internal temperature measurement fiber disposed inside the lower mold component 1 and an upper mold internal temperature measurement fiber 321 disposed in the upper mold component 2. The structure of the lower mold internal temperature measurement fiber is the same as that of the upper mold internal temperature measurement fiber 321. Taking the upper mold internal temperature measurement fiber 321 as an example, the upper mold internal temperature measurement fiber 321 is disposed on the upper mold substrate 21 along the arrangement direction of the upper heating body 23. That is, the routing shape of the upper mold internal temperature measurement fiber 321 is similar to the routing shape of the upper heating body 23, and the upper mold internal temperature measurement fiber 321 is disposed on one side of the upper heating body 23. In this embodiment, the starting point of the upper mold internal temperature measurement fiber 321 is connected to the upper substrate segment 3122, and the upper mold internal temperature measurement fiber 321 spirals through the upper heating body 23 and then connects to the outer end cable on one side of the upper heating body 23.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
