[0018] Example 1

[0019] like Figure 1 、 Figure 2 and Figure 4 As shown, the present invention proposes a polyimide resin molding device, including a body 1, a lower electric heating plate 103 and a cooling mechanism; a first extension seat 101 is installed on one side wall of the body 1, and a translation mechanism is installed between the first extension seat 101 and the body 1; the lower electric heating plate 103 is installed on the translation mechanism, and the lower electric heating plate 103 corresponds to the upper electric heating plate at the top of the body 1. The lower electric heating plate 103 is driven by the translation mechanism to adjust the lateral displacement along the body 1, approaching or moving away from the upper electric heating plate; the cooling mechanism is composed of a second extension seat 102 installed on the body 1, a mounting cover 3 installed on the top of the second extension seat 102, a material receiving assembly installed at the feeding end of the mounting cover 3, and a cooling assembly installed inside the mounting cover 3.

[0020] Furthermore, the material receiving assembly includes a screw 4, a movable seat 401 and a clamping plate 402; two groups of screws 4 are provided, and two groups of mounting ports 301 are symmetrically opened on the mounting cover 3, and the screw 4 is rotatably connected to the mounting port 301 by a motor driven by the motor installed on the mounting cover 3; the movable seat 401 is threadedly sleeved on the outside of the screw 4, and the movable seat 401 is slidingly connected to the mounting port 301; the clamping plate 402 is connected to the movable seat 401 through an electric push rod, and a shovel plate 403 is installed at the bottom end of the clamping plate 402, and the shovel plate 403 corresponds to the upper and lower mold bases at the top of the lower electric heating plate 103, so as to facilitate the separation of the lower mold base from the lower electric heating plate 103.

[0021] Furthermore, the cooling component includes a cooling seat 5, and two groups of cooling seats 5 are provided. The two groups of cooling seats 5 are symmetrically distributed between the mounting cover 3 and the second extension seat 102. The cooling seat 5 is connected to the top of the mounting cover 3 or the top of the second extension seat 102 through an electric push rod. A serpentine cavity 501 is opened inside the cooling seat 5, and a water inlet valve 502 and a water outlet valve 503 are installed on the side wall of the cooling seat 5. The water inlet valve 502 and the water outlet valve 503 are respectively connected to the inlet end and the outlet end of the serpentine cavity 501.

[0022] In this embodiment, in an initial state, the upper and lower electric heating plates 103 are located above the first extension seat 101 and away from the upper electric heating plate. The upper and lower electric heating plates 103 are started by a controller for preheating, and the upper and lower mold bases containing polyimide resin powder are placed on top of the lower electric heating plate 103. The lower electric heating plate 103 is driven by a translation mechanism to move to just below the upper electric heating plate. The upper electric heating plate is driven downward by an electric push rod to bring the upper and lower mold bases into contact with the lower electric heating plate 103 for heating and molding. After molding is completed, the motor is restarted to drive the translation mechanism to continue moving the upper and lower mold bases toward the cooling mechanism.

The screw 4 is driven by the motor to rotate and drive the moving seat 401 to slide along the installation port 301, and then the upper and lower mold bases are moved between the two sets of cooling seats 5. The electric push rod drives the two sets of cooling seats 5 to move closer to each other, and at the same time, the electric push rod drives the clamping plate 402 away from the upper and lower mold bases, so that the upper and lower mold bases fall to the lower The cooling seat 5 is placed on the side of the cooling seat 5, so that the two groups of cooling seats 5 can clamp the upper and lower mold seats. The external coolant enters the serpentine cavity 501 through the water inlet valve 502 and is discharged through the water outlet valve 503. The upper and lower mold seats are cooled by the circulating coolant, thereby accelerating the cooling and molding of the polyimide resin, shortening the cooling time, and improving the molding efficiency. After cooling, the two groups of cooling seats 5 are driven away from each other by the electric push rod, and the upper and lower mold seats on the lower cooling seat 5 can be taken out.

When the molding is completed, the motor is restarted to drive the translation seat 2 to continue moving toward the cooling mechanism, and the upper and lower mold bases on the top of the lower electric heating plate 103 can be clamped and transported by the material receiving assembly to avoid burns caused by workers directly loading and unloading materials.
