Description

Technical Field

[0001] The present invention relates to the technical field of plastic processing equipment, in particular to processing equipment for plastic-magnetic functional composite materials. Background Art

[0002] The scientific name of PA12 is polylaurolactam, also known as nylon 12. Its basic raw material is butadiene, which can be relied on petrochemicals. It is a semi-crystalline-crystalline thermoplastic material. Samarium iron nitrogen magnet refers to R2Fe 17 R2Fe formed by nitriding 17 N x or R2Fe 17 N x Samarium iron nitride (SmFeN) permanent magnets are third-generation permanent magnets. Combining the two aforementioned materials creates a plastic-magnetic functional composite material. Its advantages include a magnetic energy product of 80-111 kJ / m³ (10-14 MGOe) and a lower density than traditional magnets, resulting in component weight reduction and high process efficiency. The injection molding process supports high-volume production, shortens processing cycles, accommodates complex geometries (such as thin-walled and special-shaped parts), and exhibits excellent environmental tolerance. Furthermore, the low hygroscopicity of PA12 synergizes with the rust resistance of SmFeN magnets to extend the material's lifespan in humid and chemically corrosive environments.

[0003] It should be noted that, in the production process of the above-mentioned plastic-magnetic functional composite material, injection molding is still required by an injection molding machine. During the injection molding process of the injection molding machine, a turntable rotates a lower mold base to a position corresponding to the upper mold base, and the upper mold base moves down to close the mold with the lower mold base, and injection is performed to complete the molding of the plastic-magnetic functional composite material. However, during the injection molding process, there is no shielding measure on the lower mold base. Therefore, before and after injection, the lower mold base is in a directly exposed state, and the environment of the production workshop is complex, which makes the lower mold base or the injected product easily contaminated by impurities, and during the operation of the injection molding machine, it is inevitable that the upper mold base and the lower mold base will be misaligned. If the misalignment cannot be discovered in time, the plastic-magnetic functional composite material will be directly injected onto the surface of the lower mold base or even overflow. This will not only easily cause waste of raw materials, but also pollute the mold and generate a large amount of waste, resulting in a large amount of waste of resources. Summary of the Invention

[0064] In summary, the working principle of the processing equipment for the plastic-magnetic functional composite material provided by the embodiment of the present invention is:

[0065] When the turntable 5 drives multiple lower mold bases 7 to rotate, one lower mold base 7 rotates to the position of the installation box 803, and the lower mold base 7 rotates synchronously with the installation bottom frame 801, at this time, the upper push frame 813 is squeezed with the arc seat 814, thereby causing the upper push frame 813 to move and drive the pull-down spring 815 to be stretched, and the upper push frame 813 moves and drives the rotating opening and closing rod 812 to rotate through the upper push shaft 816, and the rotating opening and closing rod 812 drives the two isolation boxes 802 to slide and unfold on the installation bottom frame 801 through the two opening and closing sliding shafts 817, and the two opening and closing sliding shafts 817 are used to open and close the two isolation boxes 802. The shaft 817 slides in the two opening and closing grooves 818, and the lower mold base 7 is exposed. At the same time, when the isolation box 802 moves, the exhaust pipe 804 is driven to move, so that the exhaust pipe 804 pushes the sliding cover 806 to slide in the sliding groove 808 through the exhaust cover 805, and drives the return spring 809 to be stressed, so that the exhaust cover 805 is connected to the exhaust pump 807. At this time, the exhaust pump 807 extracts air through the exhaust pipe 804 and the connecting hose 819 to remove impurities on the lower mold base 7. After the injection molding is completed, the exhaust can also play an auxiliary cooling role.

[0066] Furthermore, when the injection molding seat 3 drives the upper mold base 4 to move downward for injection molding, if the position of the upper mold base 4 corresponds to the position of the lower mold base 7, the upper mold base 4 directly passes through the positioning frame 902 to complete the injection molding. If the position of the upper mold base 4 and the lower mold base 7 is misaligned, the positioning frame 902 will be squeezed to move downward, and the positioning frame 902 will move downward in the lower pressing groove 907, and the support spring 908 will be forced to shrink. The positioning frame 902 moves downward to move the driving frame 909 on the extrusion shaft 911, and then drives the driving frame 909 to move. The driving frame 909 moves and squeezes the two rotating connecting rods 904 to rotate through the two extrusion push plates 912. The rotating connecting rod 904 drives the blocking plate 903 to slide through the pulling shaft 905, so that the two blocking plates 903 close the positioning frame 902, thereby preventing plastic from dripping onto the lower mold base 7 and affecting the problem of later injection molding.

[0067] Furthermore, during the movement of the blocking plate 903, the follower push rod 1010 is synchronously driven to move, and the follower push rod 1010 squeezes the cutting rack 1005 to move, and the cutting rack 1005 moves in the telescopic slot 1003, and drives the telescopic spring 1004 to be subjected to force. At the same time, the movement of the cutting rack 1005 drives the driven push plate 1009 to move, so that the driven push plate 1009 drives the rotating cutting plate 1001 to rotate, and then the feeding tube 11 is closed, so as to avoid the waste of raw materials caused by continuous feeding when the upper mold base 4 is misplaced.

[0068] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
