[0015] The advantages of the present invention compared with the prior art are as follows: When cleaning the solid graphite in the upper die and the lower die, when the two dies are attached to the first cylinder body in opposite directions, the suction force generated by the first cylinder body is used to clean the solid graphite in the two dies at the same time, and the cleaning efficiency is higher; Because the bottom walls of some dies are not in very regular shapes, when all the first cylinder bodies are in contact with the bottom walls of the dies, different degrees of expansion and contraction can occur when the first cylinder bodies are in contact with the bottom walls of the dies to achieve adaptive fitting, so that the bottom walls of dies of different specifications can be effectively cleaned, without manually cleaning the bottom walls of the dies in different areas one by one, improving the efficiency and saving time; When the upper die and the lower die move towards each other to a predetermined position, the airbag is quickly inflated by the jet mode of the scroll air pump.

When the scroll air pump is turned on to the suction mode, the first one-way valve closes and the second one-way valve opens, generating suction inside the fixing plate, and then generating suction on the bottom walls of the dies through the first cylinder bodies to suck the graphite powder, and the graphite inside the dies and on the inner walls can be cleaned and absorbed through the sliding holes; By reciprocally switching the magnetic direction of the bidirectional electromagnet, the magnetic field directions on both sides of the bidirectional electromagnet are reciprocally switched. When the bidirectional electromagnet generates a repulsive force on the permanent magnet, the sliding rod is pushed to make the striking hammer strike one end of the second cylinder body. Cooperating with the connecting block, the first cylinder body and the contact block, the contact block on the first cylinder body vibrates the corresponding bottom wall area of the die. When the bidirectional electromagnet generates an attractive force on the permanent magnet, the striking hammer and the contact block are separated. Then, by reciprocally switching the magnetic field direction of the bidirectional electromagnet, the striking hammer continuously and intermittently strikes the bottom walls of the upper die and the lower die, vibrating the corresponding areas, improving the effect of crushing the solid graphene, and further improving the effect of sucking the graphite.

When approaching the upper mold 32, the process of cleaning the graphite is started. When moving away from the upper mold 32, the process of molding the parts is started.

[0027] In some preferred embodiments, a plurality of limiting strips 42 arranged along the circumferential direction are connected to the end of the fixed plate 8 away from the airbag 4, effectively preventing the upper mold, the lower mold and the fixed plate from being too closely attached, which affects the flow of gas and the absorption of graphite dust particles.

[0028] In some preferred embodiments, a pressure switch 43 is connected to one of the limiting strips 42 on the side where the two fixed plates 8 are separated from each other. When the upper mold 32 and the lower mold 33 move towards each other towards the fixed plate 8, when the contact switch is squeezed, an electrical signal is transmitted to the controller 20, and the controller 20 stops the pushing of the electric push rod one 34, preventing the electric push rod one 34 from being over-pushed and damaging the fixed plate 8 or the upper mold 32 or the lower mold 33. In some embodiments, the airbag also has a deflation valve to maintain the initial state of the airbag.

[0030] In some preferred embodiments, a controller 20 is connected to one of the sliding frames 36. The electric push rod one 34, the electric push rod two 41, the bidirectional electromagnet 23, the scroll air pump 27 and the pressure switch 43 are all electrically connected to the controller 20.

[0031] The specific implementation process is as follows: When a molded part is needed, the sliding plate 6 is moved away from the upper mold 32 and the lower mold 33, so that the upper mold 32 can be close to or away from under the action of the electric push rod 34. When it is necessary to clean the graphite inside the upper mold 32 and the lower mold 33, the sliding plate 6 is moved between the upper mold 32 and the lower mold 33 under the action of the electric push rod 41; After that, under the action of the electric push rod 34, both the upper mold 32 and the lower mold 33 are abutted against the fixing plate 8. The scroll air pump 27 is turned on to generate blowing gas, which passes through the first one-way valve 18. At this time, the second one-way valve 19 is closed. After the gas passes through the first one-way valve 18, it enters the airbag 4. The airbag 4 starts to expand and drives the cylinder body 5 to slide on the pipe body 9 of the fixing plate 8 until all the contact blocks 47 on the cylinder body 5 are abutted against the bottom walls of the upper mold 32 and the lower mold 33. During this process, the cylinder body 5 can slide in the pipe body 9, and the baffle 12 always slides on the inner wall of the cylinder body 5. Through the action of the ventilation pipe 11, the inner cavity of the fixing plate 8 is always communicated with the inside of the cylinder body 5 through the ventilation pipe 11; The scroll air pump 27 is turned off. Since the airbag 4 is in an expanded state, the airbag 4 is closed under the action of the first one-way valve 18. At this time, by reciprocally switching the magnetic direction of the bidirectional electromagnet 23, the magnetic field directions on both sides of the bidirectional electromagnet 23 are reciprocally switched. When the bidirectional electromagnet 23 generates a repulsive force on the permanent magnet 44, the sliding rod 25 is pushed to make the striking hammer 26 strike one end of the cylinder body 24. Cooperating with the connecting block 48, the cylinder body 5 and the contact block 47, the contact block 47 on the cylinder body 5 vibrates the corresponding mold bottom wall area. When the bidirectional electromagnet 23 generates an attractive force on the permanent magnet 44, the striking hammer 26 and the contact block 47 are separated. Then, by reciprocally switching the magnetic field direction of the bidirectional electromagnet 23, the striking hammer 26 continuously and intermittently strikes the bottom walls of the upper mold 32 and the lower mold 33, vibrating the corresponding areas to improve the effect of crushing solid graphene; After the graphene on the bottom walls of the upper die 32 and the lower die 33 is crushed by vibration, the vortex air pump 27 is turned on for suction work. The gas in the upper die 32 and the lower die 33 can suck graphene dust particles through multiple positions, including the slag suction port 46 closest to the upper die 32 and the lower die 33, and the sliding holes 10 around the cylinder body side wall scattered on the upper die 32 and the lower die 33 inside the cylinder body 5. The absorbed graphite dust particles pass through the ventilation pipe 11, the cavity in the fixing plate 8, the pipeline, the second one-way valve 19, through the first end 15 of the four-way pipeline 14, and the pipeline into the filter cylinder 28, and play a filtering role through the filter plate 29. The cover plate 30 can be opened to clean the filter plate 29. The filter plate 29 can be fixed by conventional bolts or blocks, which will not be elaborated here. Furthermore, it can simultaneously clean the particles in the upper and lower dies, and can clean the entire bottom wall area of the die (one cylinder body 5 corresponds to one area), without cleaning one area by one, and can also clean the residual solid graphite.

The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding in the prior art.

Generally speaking, if those skilled in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
