4. A method for removing bubbles using the mold for preventing bubble generation of hot pressed film according to any one of claims 1 to 3, comprising the steps of:
Step one: the plate (2) is mounted on the lower die (4), the convex hull (1) of the plate enters the matching groove (5) of the lower die (4), the exhaust rubber pushing blocks (11) on two sides of the pressing block (7) are replaced by the types matched with the edges of the convex hull (1), and the exhaust rubber pushing blocks (11) synchronously abut against the adjusting baffle rods (27) when reaching the edges on two sides of the convex hull (1) by rotating the adjusting baffle rods (27);
Step two: the hot-pressing film (28) is paved on the plate (2) and the upper die (3) is controlled to be pressed downwards, the upper die (3) is pressed downwards to drive the arched rubber air discharging block (8) to descend, after the arched rubber air discharging block (8) is contacted with the plate (2), the arched rubber air discharging block (8) is pushed to enter the containing groove (9) continuously, and meanwhile, the arched rubber air discharging block (8) is deformed in the extrusion process so that the arched rubber part of the arched rubber air discharging block is sequentially contacted with the hot-pressing film (28) from the lowest point to two sides, and therefore the hot-pressing film (28) is paved from the middle part of the back side of the convex hull (1) to two sides until the arched rubber air discharging block (8) completely enters the containing groove (9);
Step three: in the extrusion process of the arched rubber air discharging block (8), the telescopic connecting rod (14) is driven to move so as to drive the energy storage piston (13) to rise, at the moment, air is compressed and stored in the energy storage cylinder (12), when the arched rubber air discharging block (8) completely enters the storage groove (9), the energy storage piston (13) and the pushing block (19) are propped against and synchronously rise so as to push the inserting rod (20) to be separated from the blocking of the air outlet hole (16), at the moment, compressed air in the energy storage cylinder (12) instantaneously enters the firing cylinder (18) and pushes the firing piston and the air discharging push rod (10) to move, and the air discharging push rod (10) drives the air discharging rubber pushing block (11) to move to the side far away from the pressing block (7) so as to completely spread the hot pressing film (28) at the back side of the convex hull (1) so as to remove internal air bubbles;
Step four: when the lower die (4) completes hot-pressing and exhausting, the exhaust push rod (10) is contacted with the magnetic adsorption block (22) and then overcomes the elasticity of the extrusion spring (15) to adsorb, and the energy storage piston (13) descends, when the arched rubber exhaust block (8) reaches the lowest point, the nylon rope (23) connected with the energy storage piston (13) pulls the push block (19) to descend so as to overcome the adsorption force of the magnetic adsorption block (22) to apply work, and then the exhaust push rod (10) is pulled downwards to seal the air outlet hole (16) again;
Step five: and (3) repeating the steps one to four to finish the batch bubble removal hot-pressing operation of the plate (2) film hot-pressing.
