Description
Technical Field
[0001] This utility model belongs to the field of injection molding technology, and more specifically, it relates to an ultrasonic injection molding auxiliary device for thin and light cups. Background Technology
[0002] Injection molding is an industrial manufacturing process in which molten material is injected into a mold and then cooled and solidified. It is mainly used for the high-efficiency and mass production of various plastic products. Currently, in the injection molding process of thin cups, molten plastic solution is usually injected into the mold through the injection hole of the mold, filling the molding gap of the mold. After the plastic solution has completely cooled and solidified, the thin cup mold is disassembled and removed. However, in the actual injection molding process, due to the small gap of the mold for thin cups, some residual air in the mold gap is not completely discharged from the vent hole of the mold when the molten plastic solution fills the gap. This uneven filling of the plastic solution in the mold gap results in air bubbles and pores on the surface of the injection-molded thin cup, which seriously affects the injection molding quality of the thin cup. In addition, the cooled thin cup is very easy to stick to the mold surface, and the mold itself cannot automatically demold the thin cup, so manual demolding is required after injection molding. Therefore, the demolding and removal of thin cups is extremely inconvenient. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides an ultrasonic injection molding auxiliary device for thin and light cups, which solves the problems of uneven filling of the plastic solution in the mold gap during the traditional thin and light cup injection molding process, resulting in holes on the surface of the injection-molded cup and the inability of the mold itself to automatically demold the thin and light cup.

[0005] Furthermore, the slides are in two sets, each set being an inverted L-shaped structure. Each set of slides has two sets of cuboid uprights on its upper side, and the cuboid uprights of the slides have oblique through slots running from front to back. The center of the slides has a circular through hole running from left to right, and an ultrasonic transmitter is installed in the circular through hole of the slides. The transmitting end of the ultrasonic transmitter is attached to the surface of the outer diaphragm. The left side of the slides has two sets of protruding pillars near the front and rear ends, and the center of the left side of the protruding pillars has a through hole. The guide rod is inserted into the through hole of the protruding pillar of the slides.
[0006] Furthermore, the upper side of the lifting plate is provided with through holes at the four corners, and the uprights are inserted into the through holes of the lifting plate. A protruding post is provided at the center of the lifting plate, and a threaded through hole is provided on the upper side of the protruding post. Two sets of pushing posts are welded to the front and rear sides of the lifting plate. Each set of pushing posts is a cylindrical structure. The two sets of pushing posts are symmetrically distributed from left to right. The pushing posts are embedded in the inclined through groove of the rectangular upright plate of the slide.
[0007] Furthermore, the upper side of the inner mold near the edge is provided with an exhaust hole and an injection hole, and the lower side of the inner mold is provided with a circular groove at the center. The bottom of the circular groove is provided with a through hole that runs vertically through the groove. A push rod slides through the through hole of the inner mold, and a pressure plate is welded to the bottom end of the push rod. The pressure plate is embedded in the circular groove of the inner mold.
[0008] Furthermore, a ring plate is provided on the outer side of the rotating drum near the top, and the outer side of the ring plate is provided with an external tooth structure. The transmission gear is meshed with the external tooth structure of the rotating drum ring plate. The outer side of the rotating drum is provided with a threaded structure, and the threaded through hole of the lifting plate is meshed with the threaded structure of the rotating drum.
[0009] Furthermore, the number of the outer membrane devices is two sets, and each set of outer membrane devices has four sets of through holes on the front side.

In this utility model, an ultrasonic transmitter, which is inserted and installed in the through hole of the carriage, forms a close contact structure with the outer mold. The ultrasonic generator controls the ultrasonic transmitter to generate ultrasonic waves on the outer mold, causing the molten plastic solution in the gap between the outer mold and the inner mold to generate high-frequency vibrations. This breaks up the tiny air bubbles remaining in the mold gap, and promotes the rapid discharge of residual air from the vent hole of the inner mold. This ensures that the plastic solution flows and fills the mold gap fully under the vibration, avoiding air bubbles and pores on the surface of the thin cup, improving the smoothness of the surface of the thin cup, and enhancing the molding quality of the thin cup product.
[0012] 2. In this utility model, on the one hand, a drive motor drives a rotating drum to rotate through a transmission gear. This causes the threaded outer side of the rotating drum to drive the push column, which is welded to the lifting plate, along the inclined through groove wall structure of the upper and lower slide frames on the column. This allows the two sets of slide frames to drive the two sets of outer molds to move in opposite directions along the guide rod, thus realizing the automatic demolding of the cup body from the two sets of outer molds. On the other hand, the telescopic rod of the electric telescopic cylinder drives the push rod to drive the pressure plate to extend from the bottom of the inner mold. The pressure plate pushes the cooled and formed cup body downwards, thus realizing the automatic demolding of the cup body from the inner mold. This eliminates the need for manual demolding operations, making it more convenient to demold and handle the thin cup body. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0024] like Figures 1-9 As shown, this utility model provides an ultrasonic injection molding auxiliary device for thin cups, including a base plate 1; an ultrasonic generator 2 is mounted on the upper side of the base plate 1, a control unit 3 is mounted on the upper side of the ultrasonic generator 2, a loading tray 4 is welded to the upper side of the base plate 1, and a circulating cooler 6 is mounted on the upper side of the base plate 1; it also includes a column 10 and a guide rod 13; beams 9 are welded to both ends of the guide rod 13, a slide 12 is slidably connected to the outer side of the guide rod 13, and an outer mold 20 is bolted to the lower side of the slide 12; the beams 9... An electric telescopic cylinder 7 is installed at the center of the upper side of the beam frame 9. A push rod 16 is installed at the bottom of the telescopic rod of the electric telescopic cylinder 7. A drive motor 8 is installed near the left end of the upper side of the beam frame 9. A transmission gear 15 is installed on the motor shaft of the drive motor 8. A support cylinder 18 is welded at the center of the lower side of the beam frame 9. A rotating cylinder 14 is rotatably connected to the outer side of the support cylinder 18. An inner mold 19 is installed at the bottom end of the support cylinder 18. The top and bottom ends of the column 10 are both welded with the beam frame 9. A lifting plate 11 is slidably connected to the outer side of the column 10.
[0025] In this embodiment of the utility model, there are two sets of slides 12. Each set of slides 12 is an inverted L-shaped structure. The upper side of each set of slides 12 is provided with two sets of cuboid uprights. The cuboid uprights of the slides 12 are provided with oblique through grooves that run from front to back. The center of the slides 12 is provided with a circular through hole that runs from left to right. An ultrasonic transmitter 22 is installed in the circular through hole of the slides 12. The transmitting end of the ultrasonic transmitter 22 is attached to the surface of the outer mold 20. The ultrasonic transmitter 22 emits ultrasonic waves to the outer mold 20, so that the plastic solution in the gap between the outer mold 20 and the inner mold 19 forms ultrasonic vibrations, which accelerates the discharge of residual air from the vent of the inner mold 19, so that the plastic solution flows and fills the gap between the outer mold 20 and the inner mold 19 evenly, avoiding the formation of holes after the thin cup body is formed. Two sets of protrusions are provided on the left side of the slides 12 near the front and rear ends. The center of the left side of the protrusions is provided with a through hole, and the guide rod 13 is inserted into the through hole of the protrusion of the slides 12.
[0026] In this embodiment of the utility model, the four corners of the upper side of the lifting plate 11 are provided with through holes that run vertically through each other. The column 10 is inserted into the through holes of the lifting plate 11. The center of the lifting plate 11 is provided with a protruding column. The upper side of the protruding column of the lifting plate 11 is provided with a threaded through hole. Two sets of pushing columns 17 are welded to the front and rear sides of the lifting plate 11. Each set of pushing columns 17 is a cylindrical structure. The two sets of pushing columns 17 are symmetrically distributed from left to right. The pushing columns 17 are embedded in the oblique through groove of the cuboid vertical plate of the slide 12. When the lifting plate 11 moves up or down, the pushing columns 17 of the lifting plate 11 push the oblique through groove wall of the cuboid vertical plate of the slide 12. The pushing columns 17 drive the two sets of slides 12 to move in opposite directions along the guide rod 13, completing the separation and demolding of the two sets of outer molds 20.
[0027] In this embodiment of the present invention, the upper side of the inner mold 19 near the edge is provided with an exhaust hole and an injection hole, and the lower side of the inner mold 19 is provided with a circular groove at the center. The bottom of the circular groove is provided with a through hole that runs vertically through the groove. A push rod 16 is inserted and slidably inserted into the through hole of the inner mold 19. A pressure plate 23 is welded to the bottom end of the push rod 16. The pressure plate 23 is embedded in the circular groove of the inner mold 19. When the inner side of the thin cup body after cooling and forming adheres to the outer side of the inner mold 19, the telescopic rod of the electric telescopic cylinder 7 pushes the push rod 16 to move downward along the through hole of the inner mold 19, so that the pressure plate 23 welded to the bottom end of the push rod 16 extends out of the circular groove of the inner mold 19. The pressure plate 23 protrudes downward and pushes the thin cup body after cooling and forming, so that the thin cup body automatically detaches from the outer side of the inner mold 19.
[0028] In this embodiment of the utility model, a ring plate is provided on the outer side of the rotating cylinder 14 near the top. The outer side of the ring plate is provided with an external tooth structure. The transmission gear 15 is meshed and connected to the external tooth structure of the ring plate of the rotating cylinder 14. The outer side of the rotating cylinder 14 is provided with a threaded structure. The threaded through hole of the lifting plate 11 is meshed and connected to the threaded structure of the rotating cylinder 14. During the process of the drive motor 8 driving the transmission gear 15 to rotate, the transmission gear 15 drives the rotating cylinder 14 to rotate on the outer side of the support cylinder 18. The thread on the outer side of the rotating cylinder 14 drives the lifting plate 11 to move up and down along the column 10. The push column 17, which is welded and connected to the lifting plate 11, pushes the two sets of slides 12, thereby realizing the automatic separation and demolding of the two sets of outer molds 20, so that the outer side of the cooled and formed thin cup body automatically detaches from the two sets of outer molds 20.
[0029] In this embodiment of the invention, there are two sets of outer molds 20. Each set of outer molds 20 has four sets of through holes on its front side. A serpentine cooling tube 21 is inserted into each set of four sets of through holes. A liquid delivery hose 24 is installed at both the inlet and outlet ends of the serpentine cooling tube 21. A circulating cooler 6 is installed at the other end of the liquid delivery hose 24. The circulating cooler 6 injects coolant into the inlet end of the serpentine cooling tube 21 through the liquid delivery hose 24. The coolant flows in the serpentine cooling tube 21, allowing the serpentine cooling tube 21 to exchange heat and cool the outer mold 20. The cooled coolant after heat exchange flows back to the circulating cooler 6 from the outlet end of the serpentine cooling tube 21 through another set of liquid delivery hoses 24 for recooling. This allows the thin cup body wrapped by the two sets of outer molds 20 to cool and solidify quickly, shortening the cooling time of the thin cup body and improving the molding efficiency of the thin cup body.
[0030] In this embodiment of the utility model, the tray 4 is a rectangular groove structure with an opening on the upper side. A sponge pad 5 is placed on the bottom surface of the groove structure of the tray 4. The groove structure of the tray 4 is vertically opposite to the inner mold 19. The thin cup body pushed and demolded by the pressure plate 23 falls into the groove structure of the tray 4 by gravity. The sponge pad 5 at the bottom of the groove of the tray 4 buffers and supports the falling thin cup body, avoiding direct contact between the thin cup body and the bottom of the groove of the tray 4, which would cause the cup body to collide and be damaged.
[0031] Specific usage and function of this utility model embodiment: In the injection molding of a thin cup body, the control machine 3 controls the drive motor 8 via wires to rotate the transmission gear 15. Since the transmission gear 15 is meshed with the external tooth structure of the rotating cylinder 14, it drives the rotating cylinder 14 to rotate on the outer side of the support cylinder 18. Because the outer side of the rotating cylinder 14 is threadedly connected to the threaded through hole of the lifting plate 11, the rotating cylinder 14 drives the push column 17, which is welded to the lifting plate 11, to move downwards along the column 10. At this time, the push column 17 pushes downwards against the inclined through groove structure of the rectangular vertical plate of the slide 12. The two sets of slides 12 move towards each other along the guide rod 13 until the two sets of slides 12 respectively drive the two sets of outer molds 20 to make left and right contact. At this time, the outer molds 20 wrap around the left and right sides of the inner mold 19. The molten plastic is injected into the gap between the two sets of outer molds 20 and the inner mold 19 through the injection hole on the upper side of the inner mold 19. Air in the gap between the outer molds 20 and the inner mold 19 is discharged through the vent hole on the upper side of the inner mold 19. Then, the controller 3 controls the ultrasonic generator 2 to start via a wire. The ultrasonic generator 2 controls the ultrasonic transmitter 22 to emit ultrasonic waves onto the outer mold 20, which is attached to the transmitting end of the ultrasonic transmitter 22. The ultrasonic waves are transmitted through the outer mold 20 to the gap between the outer mold 20 and the inner mold 19, causing the molten plastic to vibrate and flow at high frequency in the gap. This ensures that the molten plastic fills the gap more evenly and fully. After the injection filling is completed, the ultrasonic generator 2 controls the ultrasonic transmitter 2 to start via a wire. The sound wave transmitter 22 is turned off, and the control unit 3 starts the circulating cooler 6 via a wire. The coolant in the circulating cooler 6 is delivered to the serpentine cooling pipe 21 through the infusion hose 24. The coolant flowing in the serpentine cooling pipe 21 exchanges heat with the outer mold 20 to cool the molten plastic rapidly. After cooling and shaping, the control unit 3 turns off the circulating cooler 6 via a wire. The control unit 3 then drives the drive motor 8 to rotate the transmission gear 15 in the opposite direction via a wire. The transmission gear 15 drives the rotating drum 14 to rotate in the opposite direction on the outer side of the support cylinder 18. The rotating drum 14 then drives the pushing column 17, which is welded to the lifting plate 11, to move upward along the column 10. At this time, the pushing column 17 pushes upward against the inclined through-slot structure of the rectangular vertical plate of the slide 12. The carriage 12 moves left and right in opposite directions along the guide rod 13, thereby completing the separation and demolding of the two sets of outer molds 20 from the outer surface of the thin cup body. Then, the control machine 3 controls the electric telescopic cylinder 7 to start via a wire. The telescopic rod of the electric telescopic cylinder 7 pushes the push rod 16 downward along the through hole of the support cylinder 18 and the inner mold 19. The push rod 16 drives the pressure plate 23, which is welded to the bottom end, to push the thin cup body downward, causing the thin cup body to detach from the outer side of the inner mold 19. At this time, the thin cup body falls into the upper side of the sponge pad 5 inside the groove structure of the loading tray 4 under gravity, completing the automatic demolding of the thin cup body. Finally, the control machine 3 controls the electric telescopic cylinder 7 to start again via a wire. The telescopic rod of the electric telescopic cylinder 7 pulls the push rod 16 upward along the through hole of the support cylinder 18 and the inner mold 19.The push rod 16 drives the pressure plate 23, which is welded to its bottom end, to retract into the circular groove of the inner mold 19, thereby completing the injection molding of the thin cup body.
[0032] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies. Any method that achieves the desired beneficial effect can be implemented. The ultrasonic generator 2, control unit 3, circulating cooler 6, electric telescopic cylinder 7, drive motor 8, serpentine cooling pipe 21, and ultrasonic transmitter 22 mentioned above are all common commercially available components. Upon purchase and use, simply connect them according to the instruction manual provided with the purchase; therefore, further details are omitted here.
