Description

Technical Field

[0001] The present invention relates to the field of injection molding machines, in particular to an injection molding machine for producing emergency lampshades. Background Art

[0002] An injection molding machine, also known as an injection molding machine or injection molding machine, is the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosetting plastics using plastic molding molds. Vertical injection molding machines are often used to produce lamp housings. These machines consist of a fixed mold and a movable mold mounted on top of each other, with an ejector mechanism installed on the movable mold.

[0003] The Chinese utility model patent with authorization announcement number CN214111196U discloses an injection molding machine for emergency indicator lights, including an injection molding machine body, the injection molding machine body having a fixed template for installing a mold and a movable template for pressing a film, the mold being arranged on the fixed template, the injection molding machine body being provided with a dust blowing gun, the injection molding machine body being provided with a dust collecting trough for collecting dust, the dust collecting trough being detachably connected to one side of the fixed template; when in use, the operator holds the dust blowing gun and blows air toward the dust collecting trough at the fixed template and the mold.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the following defects exist: the operator can use a dust blower to blow away the dust on the fixed template and the mold, but the dust not only exists on the fixed template and the mold, but also on the injection-molded lampshade. However, the above-mentioned related technologies do not have a structure for cleaning the dust on the injection-molded lampshade. At the same time, since the lampshade of the emergency indicator light is bowl-shaped, although it is possible to clean the inner surface of the lampshade by blowing air, it will cause dust to scatter and contaminate the fixed template and the mold again. Summary of the Invention

[0005] In order to solve the technical problem of cleaning dust on the lampshade of an emergency indicator light, the present invention provides an injection molding machine for producing the lampshade of an emergency light.

[0006] The present invention provides an injection molding machine for producing emergency lampshades, which adopts the following technical solutions:

[0008] By adopting the above technical solution, after the injection molding is completed, the ejection mechanism ejects four emergency light lampshades; then the emergency light lampshades enter between the outer surface cleaning mechanism and the inner surface cleaning mechanism, and then the lower cleaning cover rises to support the emergency light lampshades, and then the upper cleaning cover descends. During this process, the runner slurry cutting assembly removes the horizontal runner slurry and the vertical runner slurry, and then the outer cleaning assembly cleans the outer surface of the emergency light lampshade, and the inner cleaning assembly cleans the inner surface of the emergency light lampshade. During this process, the external air exhaust device is started, so that the air flow enters through the filter on the upper cleaning cover and then leaves from the exhaust pipe on the lower cleaning cover, thus forming a top-down airflow, and the dust cleaned by the outer cleaning assembly and the inner cleaning assembly is collected in the lower cleaning cover, which cleans the emergency light lampshade well and collects the dust, and at the same time completes the separation of the emergency light lampshade and the runner slurry.

[0009] Optionally, the external cleaning assembly includes four square-distributed external cleaning seats; the external cleaning seat includes a rectangular plate-shaped external cleaning plate; the external cleaning plate is rotatably arranged on the upper side wall of the upper cleaning cover; an external mounting groove is formed on the lower end face of the external cleaning plate and cooperates with the outer surface of the emergency light lampshade; an external cleaning layer is provided on the side wall of the external mounting groove.

During this process, the vertical runner slurry first passes vertically through the vertical perforation, and then a pair of cutting knives cut off the horizontal runner slurry resting on a pair of cutting pads; then the cutting auxiliary clamping claw cylinder clamps the vertical runner slurry, and then the cutting electric cylinder drives the cutting lifting plate to rise and return to its position, so that the horizontal runner slurry and the vertical runner slurry are brought up, so that after the runner slurry is cut off, it will not affect the subsequent cleaning of the outer surface of the emergency light lampshade.

[0015] Optionally, the inner cleaning assembly includes four square-distributed inner cleaning brushes; the inner cleaning brush includes an inner cleaning brush rod; the upper end of the inner cleaning brush rod is formed with an inner cleaning seat that cooperates with the inner surface of the emergency light lampshade, and the lower end is formed with a rotating connecting seat; an inner cleaning layer is provided on the upper surface of the inner cleaning seat; the lower end of the lower cleaning cover is detachably connected to a driving frame; the driving frame is a rectangular box with an open upper end; an inner cleaning motor is fixed in the middle of the bottom surface of the driving frame; a center gear is fixed on the upper end of the inner cleaning motor; four square-distributed inner cleaning gears are rotatably provided on the lower side wall of the driving frame; the center gear is respectively meshed with the four inner cleaning gears; the rotating connecting seat consists of a circular plate and a number of key blocks uniformly formed on the cylindrical surface of the circular plate; four connecting through-holes for the rotating connecting seat to vertically pass through are formed on the lower side wall of the lower cleaning cover; the center of the upper end surface of the inner cleaning gear is formed with a connecting slot that cooperates with the rotating connecting seat.

[0017] Optionally, four square-distributed circular cylindrical connecting rings are formed on the lower side wall of the driving frame; the connecting rings correspond one-to-one with the connecting through-holes and are coaxially arranged; the inner diameter of the connecting ring is the same as the diameter of the connecting through-hole; an external thread is formed on the outer cylindrical surface of the connecting ring; a sealing cover is provided on the inner cleaning brush rod; a sealing ring is provided between the sealing cover and the inner cleaning brush rod; the lower end of the sealing cover is formed with an internal thread that cooperates with the external thread of the connecting ring.

[0018] By adopting the above technical solution, the sealing cover covers the connecting through-hole to prevent dust from entering the connecting through-hole and affecting the subsequent collection and cleaning of dust in the lower cleaning cover.

[0019] Optionally, a rectangular frame-shaped connecting bracket is formed on the lower end surface of the upper cleaning cover; and a plug-in slot for vertically inserting the connecting bracket is formed on the upper end surface of the lower cleaning cover.

[0024] By adopting the above technical solution, after the emergency lampshade is cleaned, the lower cleaning cover moves downward to drive the emergency lampshade and the runner aggregate to descend together, which makes it convenient to remove the emergency lampshade and the runner aggregate.

[0025] Optionally, a lampshade translation mechanism is provided on the cleaning bracket; the lampshade translation mechanism is used to translate the four emergency light lampshades pushed upward by the ejection mechanism to between the outer surface cleaning mechanism and the inner surface cleaning mechanism.

[0026] By adopting the above technical solution, the lampshade translation mechanism moves the emergency lampshade ejected by the ejection mechanism between the outer surface cleaning mechanism and the inner surface cleaning mechanism, thereby avoiding accidental injuries when manually taking it.
