As an embodiment of the invention, one end of the fixing element 7, which is far away from the push plate 6, is fixedly connected with a knocking block 76; when the extrusion device works, after the pushing disc 6 drives the ring sleeve 71 to be far away from the second magnet 75, the second spring 72 drives the ring sleeve 71 to move close to the knocking block 76, so that the knocking block 76 collides with the ring sleeve 71, the ring sleeve 71 and the knocking block 76 vibrate after being impacted, the knocking block 76 transmits the vibration force to the pushing disc 6, the pushing disc 6 drives the material cylinder 2 to vibrate, the material cylinder 2 can drive the inner raw material to vibrate in the vibrating process, bubbles in the raw material float upwards under the vibrating action, so that the bubbles in the raw material are far away from the through hole 21 and are matched with the pushing disc 6 to extract gas below the pushing disc 6, the risk that the gas enters the extrusion cylinder 4 along the through hole 21 is further avoided, and the quality of the product manufactured by the extrusion device is further improved.

The specific working process is as follows:

the staff firstly cleans and dries the waste plastics, and then pours the waste plastics into the interior of the material cylinder 2, so that the waste plastics can fall on the upper end of the push disc 6, the second motor 23 drives the turntable 24 to plug the opening of the material cylinder 2, and the controller can control the resistance wire 26 to heat, and the resistance wire 26 can generate heat after being heated, so that the waste plastics on the upper end of the push disc 6 can be heated and melted, and then the controller can control the hydraulic cylinder 22 to drive the push disc 6 to slide upwards along the inner wall of the material cylinder 2, and the waste plastics can be melted to form the raw material, and the raw material can be extruded by the push disc 6 to open the first check valve 62, so that the raw material enters the first step hole 61, the raw material in the first step hole 61 can fall under the action of gravity to the lower part of the push disc 6, and can slide downwards along with the hydraulic cylinder 22 driving the push disc 6 along the inner wall of the material cylinder 2, so that the raw material below the push disc 6 is extruded by the push disc 6, the raw materials below the push disc 6 enter the extrusion cylinder 4 through the cooperation of the raw materials with the self gravity of the raw materials, the first motor 3 drives the stud 41 to rotate, so that the raw materials in the extrusion cylinder 4 enter the first die 42 along the through hole 43 under the action of the stud 41, the raw materials are filled between the first die 42 and the second die 51, then the raw materials between the first die 42 and the second die 51 are cooled by workers, the second die 51 is driven to be far away from the first die 42 through the controller controlled electric push rod 5, the purpose of demolding is achieved, the workers take out the molded product from the space between the first die 42 and the second die 51, and the purposes of energy conservation and environmental protection are achieved through the manufactured product; the resistance wires 26 around the extrusion cylinder 4 and the first die 42 are electrified, so that the raw materials are prevented from being solidified due to too low temperature in the forming process, cooling holes are formed in the second die 51 and the first die 42, so that a hydraulic pump injects cooling liquid into the cooling holes, the water cooling purpose is realized, and the formed product can be cooled; the feeding mode of the workers is quantitative feeding; after the product is injected, pressure maintaining treatment needs to be carried out on the production in the first die 42 and the second die 51 after 1-2 seconds, and the pressure maintaining mode is that the stud 41 extrudes raw materials to a position between the first die 42 and the second die 51, so that the fused raw materials fill and contract gaps in the first die 42 and the second die 51, the internal raw material pressure of the first die 42 and the second die 51 is ensured to be 70-80MPa, and the pressure maintaining time is consistent with the cooling forming time; because the melted waste plastics are positioned at the upper end of the push disc 6, the push disc 6 moves upwards under the drive of the hydraulic cylinder 22, because the first spring 65 in the first check valve 62 has certain elasticity, certain negative pressure can be formed after the lower part of the push disc 6 moves, gas in the raw material below the push disc 6 can be pumped out, the gas below the push disc 6 is ensured to be positioned above the raw material, the gas cannot enter the extrusion cylinder 4 along the through hole 21, the raw material at the upper end of the push disc 6 can be extruded below the push disc 6 after the push disc 6 moves upwards, the raw material cannot block the second stepped hole 63 due to the action of the blocking disc 8, and meanwhile, in the process that the raw material below the push disc 6 moves downwards along the inner wall of the charging cylinder 2, the push disc 6 can open the blocking disc 8 to discharge the gas below the second stepped hole 63, thereby preventing the gas from entering the extrusion cylinder 4 to cause the phenomenon of air holes on the formed product, and improving the quality of the product made by the forming machine; the gas above the push disk 6 flows away after the charging barrel 2 is opened; because the first spring 65 in the second check valve 64 has certain pressure, the pushing disc 6 has certain pressure when pushing the raw material below the pushing disc 6, and then the certain pressure is matched with the pressure generated by the self weight of the raw material and the rotation of the stud 41, so that the raw material in the charging barrel 2 is ensured to enter the extruding barrel 4; when the push disc 6 slides upwards along the inner wall of the charging barrel 2, the push disc 6 drives the ring sleeve 71 and the stirring rod 73 to move upwards, the ring sleeve 71 and the stirring rod 73 are hindered by raw materials at the upper end of the push disc 6 in the movement process, so that the ring sleeve 71 extrudes the second spring 72, after the push disc 6 stops moving, the second spring 72 pushes the ring sleeve 71 and the stirring rod 73 to move, the raw materials at the upper end of the push disc 6 are stirred by the stirring rod 73, further, waste plastics which are not melted are pushed away by the stirring rod 73, the situation that the waste plastics which are not melted are completely hindered by the melted waste plastics from flowing is prevented, meanwhile, all particles of the raw materials at the upper end of the push disc 6 are distributed more uniformly under stirring, and the quality of products manufactured by a forming machine is improved; because the fixing piece 7 is in threaded connection with the ring sleeve 71, the ring sleeve 71 and the stirring rod 73 can rotate around the fixing piece 7 after being blocked by raw materials, so that the range of stirring the raw materials at the upper end of the push disc 6 by the stirring rod 73 is enlarged, the raw materials are distributed more uniformly under stirring, the improvement of the melting uniformity of the waste plastics is facilitated, the melting efficiency of the waste plastics is improved, and the raw material supply efficiency of the charging barrel 2 is improved; in the process that the ring sleeve 71 is driven by the push disc 6 to move close to the rotary disc 24, the first magnet 74 on the ring sleeve 71 and the second magnet 75 on the rotary disc 24 repel each other, so that the ring sleeve 71 overcomes the elastic force of the second spring 72 and rotates around the fixing piece 7 under the action of the magnetic force, after the ring sleeve 71 is driven by the push disc 6 to be far away from the second magnet 75, the ring sleeve 71 restores to the original position relative to the push disc 6 under the action of the second spring 72, and the condition that the force generated by the blocking of raw materials on the ring sleeve 71 is smaller than the elastic force of the second spring 72 is prevented, and the implementation of the invention is further ensured; after the pushing disc 6 drives the ring sleeve 71 to be far away from the second magnet 75, the second spring 72 drives the ring sleeve 71 to move close to the knocking block 76, so that the knocking block 76 collides with the ring sleeve 71, the ring sleeve 71 and the knocking block 76 vibrate after being impacted, the knocking block 76 transmits the vibration force to the pushing disc 6, the pushing disc 6 drives the material barrel 2 to vibrate, the material barrel 2 can drive the inner raw material to vibrate in the vibrating process, bubbles in the raw material float upwards under the vibrating action, so that the bubbles in the raw material are far away from the through hole 21 and are matched with the pushing disc 6 to extract gas below the pushing disc 6 after moving upwards, the risk that the gas enters the extruding barrel 4 along the through hole 21 is further avoided, and the quality of the product manufactured by the invention is further improved.
