Referring to fig. 4 and 6, the hot press device 5 further includes a temperature control system 6 for monitoring the temperatures of the upper die 51 and the lower die 52, and the temperature control system 6 includes a control terminal 65, a temperature detection module 61, a threshold module 62, a comparison module 64, a calling module 63, and a trigger module 67; the control terminal 65 is used for controlling the heating plate 53 to heat the upper die 51 and the lower die 52 and controlling the upper die 51 and the lower die 52 to perform hot-pressing work; the temperature detection module 61 is used for detecting the temperatures of the upper die 51 and the lower die 52 in real time; the threshold module 62 is configured to provide a temperature value for heating the heating plate 53, and a temperature preset value database corresponding to a heatable temperature of the heating plate 53 is built in the threshold module; the retrieving module 63 is coupled to the threshold module 62 and retrieves a desired preset value from the database of preset temperature values and sets the temperature stored in the database; the comparing module 64 is coupled to the temperature detecting module 61 for receiving the detected temperature when the hot press device 5 is in the working state and comparing the detected temperature with the preset temperature value retrieved by the retrieving module 63; the trigger module 67 is controlled by the comparison module 64, and when the temperature detected by the temperature detection module 61 is less than the preset temperature value, the trigger control terminal 65 controls the heating plate 53 to heat the upper die 51 and the lower die 52; on the contrary, when the temperature detected by the temperature detecting module 61 is greater than the preset temperature value, the control terminal 65 is not triggered.
Further, in the hot pressing process, the temperatures that the upper die 51 and the lower die 52 can be raised are constant, the temperature of the second medium-temperature heating part corresponding to the first medium-temperature heating part needs to be kept the same, and the temperature of the second side-temperature heating part corresponding to the first side-temperature heating part also needs to be kept the same; the temperature preset value database comprises a first middle temperature threshold database 661 storing the heating temperature of the first middle heating part 511, a first side temperature threshold database 662 storing the heating temperature of the first side heating part 512, a second middle temperature threshold database 663 storing the heating temperature of the second middle heating part 521, and a second side temperature threshold database 664 storing the heating temperature of the second side heating part 522, wherein the temperature threshold in the first middle temperature threshold database 661 corresponds to the temperature threshold in the second middle temperature threshold database 663 one by one and changes with the temperature data in the second middle temperature threshold database 663, and the temperature threshold in the first side temperature threshold database 662 corresponds to the temperature threshold in the second side temperature threshold database 664 one by one and changes with the temperature data in the second side temperature threshold database 664; when the heating temperature of the heating plate 53 is set, the first intermediate-temperature heating portion and the first side-temperature heating portion can be changed along with the setting only by setting the temperature thresholds of the second intermediate-temperature heating portion and the second side-temperature heating portion, so that the setting of the heating temperature of the whole heating plate 53 is more convenient.
Further, the temperature threshold in the first medium-temperature threshold database 661 is smaller than the corresponding temperature threshold in the second medium-temperature threshold database 663; the temperature threshold in the first edge temperature threshold database 662 is smaller than the corresponding temperature threshold in the second edge temperature threshold database 664; because the lower die 52 moves upwards to carry out hot pressing on the lower cloth and the sponge two layers, compared with the upper die 51 for carrying out hot pressing on the upper cloth one layer after a period of time, the lower die 52 has higher cooling and heat dissipation speed, and because the temperature threshold set by the upper die 51 fluctuates along with the lower die 52, the threshold of each heating part of the upper die 51 is set to be smaller than that of the lower die 52, so that when the lower die 52 is heated again by the subsequent heating plate 53, the heating of the upper die 51 can be reduced.
The temperature thresholds in the first medium temperature threshold database 661 correspond to the temperature thresholds in the first side temperature threshold database 662 one to one, and the temperature thresholds in the first medium temperature threshold database 661 are smaller than the corresponding temperature thresholds in the first side temperature threshold database 662; the temperature thresholds in the second moderate temperature threshold database 663 correspond to the temperature thresholds in the second side temperature threshold database 664 one to one, and the temperature thresholds in the second moderate temperature threshold database 663 are smaller than the corresponding temperature thresholds in the second side temperature threshold database 664.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
