Description

Technical Field

[0001] The utility model relates to the technical field of forming machines for processing filters, in particular to a forming machine for processing a conical end cover of a filter. Background Art

[0002] The filter is an indispensable device on the medium conveying pipeline. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve and water level valve. The filter consists of a cylinder, a stainless steel filter screen, a sewage discharge part, a transmission device and an electrical control part. After the water to be treated passes through the filter cartridge of the filter screen, its impurities are blocked by the stainless steel filter screen to achieve the purpose of filtration. When cleaning is required, just take out the detachable filter cartridge, open the conical end cover on the filter cartridge, and reinstall it after treatment. When producing the filter cartridge, a plastic molding machine is required. The existing plastic molding machine controls the opening and closing of the mold group through the extension and contraction of multiple hydraulic cylinders. The mold group is closed when the hydraulic cylinder is extended, and vice versa. When working, the mold group is closed first, and the external hydraulic pump station Continuing to work keeps the hydraulic cylinder maintaining pressure, so that the mold group is in a closed state. The external injection molding machine injects the plasticized molten plastic into the closed mold cavity through the injection hole. After solidification and shaping, the hydraulic cylinder contracts the mold group to open, and the electric push rod extends to eject the finished workpiece. The mold group of the traditional plastic molding machine controls the opening and closing of the mold group through the extension and contraction of multiple hydraulic cylinders. The equipment cost and subsequent operation and maintenance cost are high. The hydraulic cylinder does not have self-locking performance. During injection molding, the external hydraulic pump station needs to work continuously to ensure the pressure of the hydraulic cylinder, which can easily lead to hydraulic failure. After the workpiece is formed, it will adhere to the mold group. The finished workpiece is directly ejected by the electric push rod, which can easily damage the workpiece. For this reason, we propose a molding machine for processing conical end covers of filters. Utility Model Content

[0026] The working principle of the molding machine for processing the conical end cap of the filter provided by the utility model is as follows: when the conical end cap of the filter is molded, the worm wheel 632 and the worm 633 are meshed to form a mechanical self-locking, so that the mold group consisting of the left mold 3, the right mold 4 and the upper mold 5 is in a closed state, the discharge port of the external injection molding machine is aligned with the injection molding port 7, and the plasticized molten plastic is injected into the closed mold group through the injection molding port 7. The molten plastic forms the shape of the conical end cap of the filter in the mold cavity of the mold group. After the plastic cools, a conical end cap of the finished filter is formed. The single-chip computer 8 controls the operation of the motor 1 631. The output shaft of the motor 1 631 drives the worm gear 632 to rotate, and the worm 633 also rotates, driving the gear 61 to rotate. As the gear 61 rotates, the rack plate 1 621 moves right, driving the right mold 4 to move right synchronously. The rack plate 2 622 moves left, driving the left mold 3 to move left synchronously. The rack plate 3 623 moves up, driving the upper mold 5 to move up synchronously. The mold group opens. At the same time, the single-chip computer 8 controls the operation of the motor 2 644. The output shaft of motor 2 644 drives cam 646 to rotate. As cam 646 rotates, notch 645 continuously passes by the protrusion. When notch 645 aligns with the protrusion, moving block 641 does not move. When notch 645 passes by the protrusion, the edge of notch 645 squeezes the protrusion, causing moving block 641 to move up slightly, and top column 643 also moves up slightly. The elastic deformation of spring 642 makes moving block 641 always stick to the surface of cam 646, so that the upper end of top column 643 continuously contacts the lower end of the conical end cover of the finished filter. , forming a vibration effect, so that the conical end cover of the finished filter is quickly separated from the mold group. As the cam 646 continues to rotate, the raised part of the cam 646 contacts the lower end of the moving block 641 and squeezes the moving block 641, so that the moving block 641 moves upward, the spring 642 is forced to shrink, and the ejector column 643 also moves upward synchronously, ejecting the conical end cover of the finished filter that has been separated from the mold group. The vibration can make the conical end cover of the finished filter quickly and completely separated from the mold group, avoiding damage to the conical end cover of the finished filter during ejection.
