[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a heating and pressure-maintaining mechanism, which includes a frame 101, a pressing assembly is provided on the upper end of the frame 101, and the pressing assembly includes a lifting mechanism 102 and a hot pressing profiling jig 103 driven by the lifting mechanism 102. A translation assembly 108 is provided below the frame 101, and a moving plate 109 is provided on the translation assembly 108. An adaptive assembly is provided on the moving plate 109, and the adaptive assembly is located below the pressing assembly. Figures 4 to 7As shown, the adaptive assembly includes a base 106, an intermediate fixing block 105, and multiple outer sliders 104. The base 106 can be composed of multiple blocks connected by bolts. The upper end of the slider 104 is provided with a pressure portion 1042. The intermediate fixing block 105 is fixed to the base 106. The outer wall of the intermediate fixing block 105 is circumferentially provided with multiple outwardly inclined guide rails 1051. The outer sliders 104 are provided with inclined sliding grooves 1041. Each outer slider 104 is arranged circumferentially along the outer wall of the intermediate fixing block 105. The sliding grooves 1041 of the outer sliders 104 slide in conjunction with the corresponding guide rails. Below each outer slider 104 is provided a slider reset assembly 107 mounted on the base 106.

[0045] It is understandable that multiple pressing components can be set on the frame 101 at the same time, and multiple adaptive components can be set on the movable plate 109.

[0046] Specifically, the slider reset assembly 107 includes a spring mounting pin and a spring sleeved on the spring mounting pin. One end of the spring is mounted on the base 106. The slider 104 is supported by the spring mounting pin. The spring mounting pin moves up and down relative to the base 106. The downward movement of the spring mounting pin compresses the spring. The compressed spring drives the spring mounting pin upward, thereby causing the slider 104 to reset. It is understood that the slider reset assembly 107 may also be other types of elastic elements.

[0047] Specifically, the hot pressing profiling jig 103 includes a profiling cavity for accommodating the product 200 , and the profiling cavity faces the adaptive component below.

[0048] Specifically, at the unloading station, the sliders 104 are retracted, and the product 200 to be held under pressure is placed on the adaptive assembly. Each slider 104 is located inside the product 200. Then, the translation assembly 108 transports the adaptive assembly and the product 200 to the holding station. At the holding station, the hot pressing profiling jig 103 descends, allowing the product 200 to enter the profiling cavity of the hot pressing profiling jig 103. The product 200 is located between the sliders 104 and the hot pressing profiling jig 103. As the hot pressing profiling jig 103 descends further, the hot pressing profiling jig 103 applies pressure to the product 200, forcing the product 200 to press down on each slider 104. Each slider 104 moves downward and outward along the corresponding outwardly inclined guide rails 1051, that is, the sliders 104 separate from each other, thereby causing each slider 104 to apply force to the inner surface of the product 200, so that the product 200 can be closely attached to the hot pressing profiling jig 103. After the holding period is complete, the hot pressing profiling jig 103 rises, and the sliders 104 move upward and retract under the action of the slider reset assembly 107. Next, the translation assembly 108 transports the product 200 and the adaptive assembly back to the unloading station. At the unloading station, the product 200 that has completed the holding period can be removed, and then a new product 200 that needs to be held can be placed on the adaptive assembly.

[0049] In one embodiment, Figures 8 to 10As shown, the lifting mechanism 102 includes a lifting cylinder 1021, a guide rod 1027 and a lower pressing block 1022. A linear bearing is provided on the frame 101. The guide rod 1027 slides with the linear bearing. One end of the guide rod 1027 is connected to the hot pressing profiling fixture 103. The other end of the guide rod 1027 is provided with an end plate 1027a. A sleeve is provided between the end plate 1027a and the linear bearing. The spring 1028 on 7, the lifting cylinder 1021 is installed on the frame 101, the lifting cylinder 1021 is connected to the lower pressing block 1022, the bottom end of the lower pressing block 1022 is provided with a buffer block 1023, the lower pressing block 1022 is located above the hot pressing profiling jig 103, the lower pressing block 1022 is provided with a guide pin 1024, the lower end of the guide pin 1024 is connected to the hot pressing profiling jig 103, the upper end of the guide pin 1024 is provided with a A limiting portion is provided, which is located above the lower pressing block 1022. The hot pressing profiling jig 103 is provided with a first type of through hole, and a linear bearing is provided in the first type of through hole. The pressing block is provided with a second type of through hole, which is a stepped hole. It also includes an extrusion rod 1025, the lower end of the extrusion rod 1025 is located in the profiling cavity, and the upper end of the extrusion rod 1025 passes through the linear bearing of the first type of through hole and the second type of through hole in sequence. A limiting head 1025a is provided at the upper end of the extrusion rod 1025, and a limiting plug-in plate 1026 is provided at the top of the pressing block. The limiting plug-in plate 1026 is located below the limiting head 1025a. A spring positioning platform is provided on the extrusion rod 1025, and a spring 1029 is provided on the outer sleeve of the extrusion rod 1025. One end of the spring 1029 abuts against the spring positioning platform, and the other end of the spring 1029 is located in the second type of through hole and abuts against the stepped surface in the second type of through hole.

[0050] Specifically, when the hot pressing profiling jig 103 descends, the extrusion rod 1025 moves upward under the pressure exerted by the product 200, thereby compressing the spring 1029. When the hot pressing profiling jig 103 ascends, the extrusion rod 1025 moves downward under the action of the spring 1029, thereby exerting a downward thrust on the product 200, thereby helping to separate the product 200 from the hot pressing profiling jig 103.

[0051] In one embodiment, Figure 9 and Figure 10 As shown, a pressing portion 1025b is provided at the lower end of the extrusion rod 1025, and the hot pressing profiling jig 103 is provided with a receiving hole 1031 for receiving the pressing portion 1025b, and the receiving hole 1031 is communicated with the first type of through hole.

[0052] Specifically, when the extrusion rod 1025 moves upward, the pressing portion 1025 b of the extrusion rod 1025 enters the receiving hole 1031 .

[0053] In one embodiment, the hot pressing and profiling jig 103 is provided with a heating rod. For example, the heating rod can be inserted transversely into the hot pressing and profiling jig 103. The heating rod is used to heat the hot pressing and profiling jig 103. The heating rod and the temperature control system connected to the heating rod can be implemented using existing equipment.

[0054] In one embodiment, Figure 5 As shown, the intermediate fixed block 105 is provided with an intermediate cavity 1052 , and an intermediate moving block 110 is provided in the intermediate cavity 1052 and moves up and down along the intermediate cavity 1052 . A moving block reset assembly 111 is provided below the intermediate moving block 110 .

[0055] Specifically, the movable block reset assembly 111 is configured similarly to the slider reset assembly 107. For example, it includes a spring mounting pin and a spring sleeved on the spring mounting pin. The lower end of the spring is mounted on the base 106. The spring mounting pin supports the intermediate movable block 110. The spring mounting pin moves up and down relative to the base 106. The downward movement of the spring mounting pin compresses the spring. The compressed spring drives the spring mounting pin upward, thereby causing the intermediate movable block 110 to reset. It is understood that the movable block reset assembly 111 may also be other types of elastic elements.

[0056] In one embodiment, the intermediate fixed block 105 is equipped with a heating rod. Specifically, the heating rod can be vertically inserted into the intermediate fixed block 105, and a corresponding through-hole is provided in the base 106 for the heating rod to pass through. The heating rod is used to heat the intermediate fixed block 105. The heat from the intermediate fixed block 105 can be transferred to the product 200 through the intermediate movable block 110 and the slider 104.

[0057] In one embodiment, steps 1053 are provided at both ends of the middle cavity 1052 of the middle fixed block 105 . The steps 1053 are used to cooperate with both ends of the middle movable block 110 .

[0058] In one embodiment, the translation assembly 108 includes a motor 1081, a synchronous belt assembly 1082, and a linear guide assembly 1083. The motor 1081 is connected to the synchronous belt assembly 1082, and the movable plate 109 is connected to the linear guide assembly 1083. The movable plate 109 is also connected to the synchronous belt assembly 1082. Specifically, the motor 1081 is used to drive the synchronous belt assembly 1082. The synchronous belt assembly 1082 can be composed of a synchronous belt and synchronous pulleys, which are conventional structures. The movable plate 109 is connected to the synchronous belt via a clamp. The movement of the synchronous belt drives the movable plate 109 to move.

[0059] In one embodiment, photoelectric sensors 122 are provided at each end of the linear guide assembly 1083, and a sensing plate 121 is provided at the lower end of the movable plate 109. The sensing plate 121 is used to trigger the photoelectric sensors 122 to generate a signal. The photoelectric sensors 122 are used to detect the position of the movable plate 109. When the movable plate 109 moves into position, the photoelectric sensors 122 generate a signal, prompting the motor 1081 to stop.

[0060] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
