[0024] In order to produce two-color / two-material or multi-color / multi-material plastic products more efficiently, some manufacturers have developed a molding mold with a glue inlet at the top side, that is, the molding mold is additionally provided with a glue inlet at the top side on the basis of the original horizontal glue inlet, and two or more different materials are injected into the molding mold at the same time through the combination of the horizontal glue inlet and the top side glue inlet to produce two-color / two-material or multi-color / multi-material plastic products; therefore, there is an urgent need for a top side injection device that can be applied to a molding mold with a glue inlet at the top side, and whose injection assembly can be adjusted in multiple directions to cooperate with molding molds of different specifications, thereby improving the compatibility of the injection device.

[0025] In order to solve the above technical problems, the present invention proposes a sky-side injection device.

In this way, the Z-axis translation component 400, the X-axis translation component 500 and the Y-axis translation component 600 are used to respectively realize the displacement of the injection assembly 700 along the X-axis direction and / or the Y-axis direction and / or the Z-axis direction, and the structure is simple and practical. In actual operation, the Z-axis translation component 400, the X-axis translation component 500 and the Y-axis translation component 600 can be set at will according to the on-site conditions, or all three can be set at the same time, and this application does not make specific restrictions on them.

It can be understood that on the basis of understanding the technical solution of this embodiment, technical personnel in the field can creatively associate other first driving mechanisms 420 other than the first driving cylinder 421 without paying attention, and they should also belong to the protection scope of this application.

[0033] Furthermore, a first ball bearing (not shown in the drawings) is provided in the first guide rail slider to change the movement mode of the first guide rail slider and the first linear guide rail 411 from sliding movement to rolling movement, so that the Z-axis translation movement of the projection shift seat 310 is smoother.

[0034] Furthermore, a first electronic ruler (not shown in the drawings) can be arranged on the moving path of the shooting and displacement seat 310, and the first electronic ruler is electrically connected to the first driving cylinder 421; with such arrangement, the first electronic ruler is used to measure the moving distance of the shooting and displacement seat 310 in real time, and when the shooting and displacement seat 310 moves to the specified position, the first electronic ruler sends a signal to the first driving cylinder 421 to stop the first driving cylinder 421 from outputting the movement of the shooting and displacement seat 310; thereby, the position control accuracy of the shooting and displacement seat 310 is high, and the operation is convenient and reliable.

[0036] Among them, the second driving mechanism 520 includes a second driving cylinder 521, the second driving cylinder 521 is installed on the mounting plate 330, and the driving end of the second driving cylinder 521 is connected to the support frame 320. In this way, the second driving cylinder 521 is used as a power source to drive the support frame 320 to move, and the structure is simple and practical. It can be understood that on the basis of understanding the technical solution of this embodiment, technical personnel in the field can think of other second driving mechanisms 520 other than the second driving cylinder 521 without creatively paying attention, and they should also belong to the protection scope of this application.

[0037] Furthermore, a second ball bearing (not shown in the drawings) is provided in the second guide rail slider 512 to change the movement mode of the second guide rail slider 512 and the second linear guide rail 511 from sliding movement to rolling movement, so that the X-axis translation movement of the support frame 320 is smoother.

[0038] Furthermore, a second electronic ruler (not shown in the drawings) can be arranged on the moving path of the support frame 320, and the second electronic ruler is electrically connected to the second driving cylinder 521; with such arrangement, the moving distance of the support frame 320 is measured in real time by the second electronic ruler, and when the support frame 320 moves to the specified position, the second electronic ruler sends a signal to the second driving cylinder 521 to stop the second driving cylinder 521 from outputting the movement of the support frame 320; thereby, the position control accuracy of the support frame 320 is high, and the operation is convenient and reliable.

[0039] Specifically, the Y-axis translation component 600 includes a third guide mechanism 610 and a third drive mechanism 620; the third guide mechanism 610 includes two third linear guide rails 611 extending along the Y-axis direction, the two third linear guide rails 611 are arranged parallel to each other on the mounting base 200, the mounting plate 330 is provided with a third guide rail slider 612, and the third guide rail slider 612 is slidably connected to the third linear guide rail 611; the third drive mechanism 620 is used to drive the mounting plate 330 to move along the third linear guide rail 611's track movement; in this way, the mounting plate 330 equipped with the X-axis translation component 500 is slidably connected to two sections of the third linear guide 611 extending along the Y-axis direction, so that the third linear guide 611 can be used to limit and guide the translation of the mounting plate 330; then, under the driving action of the third driving mechanism 620, the mounting plate 330 can be translated along the track direction of the third linear guide 611, that is, the Y-axis direction, so as to realize the movement of the injection assembly 700 along the Y-axis direction.

In this way, the screw transmission structure is used to realize the movement of the mounting plate 330 along the Y-axis direction, and the structure is simple and practical. At the same time, since the first driving cylinder 421 and the second driving cylinder 521 are both driven by oil pressure, there are certain requirements for the arrangement of the hydraulic oil circuit; and the third driving mechanism 620 adopts a screw transmission structure, which can save the arrangement of the hydraulic oil circuit and save costs. It can be understood that on the basis of understanding the technical solution of this embodiment, the technical personnel in the field can creatively associate other specific structures of the third driving mechanism 620 without paying attention, and they should also belong to the protection scope of this application.

[0041] Furthermore, an adjusting wheel 625 is fixedly connected to one end of the lead screw, so that an operator can rotate the lead screw 621 by manually rotating the adjusting wheel 625, which is light, fast and easy to achieve a self-locking function.

[0042] Furthermore, a third ball bearing (not shown in the drawings) is provided in the third guide rail slider 612 to change the movement mode of the third guide rail slider 612 and the third linear guide rail 611 from sliding movement to rolling movement, so that the Y-axis translation movement of the mounting plate 330 is smoother.

[0043] As a preferred solution of the above embodiment, refer to the attached Figure 5-6The injection assembly 700 includes a plasticizing component 710, a pre-plasticizing component 720 and an injection molding component 730; the plasticizing component 710 includes a barrel 711 and a screw 720 rotatably arranged inside the barrel 711; a feeding hole 7111 for feeding plastic is provided on the side of the barrel 711, and a glue injection nozzle 7112 is provided at one end of the barrel 711 facing the glue inlet; the pre-plasticizing component 720 is used to drive the screw 720 to rotate so that the plastic moves to the glue injection nozzle 7112 under the push of the screw 720; the injection molding component 730 is used to apply a force on the plasticizing component 710 toward the glue inlet. With such arrangement, after the plastic enters the inner cavity of the barrel 711 through the feed hole 7111, the pre-plastic component 720 drives the screw 720 to rotate, so that the plastic moves to the injection nozzle 7112 under the push of the screw 720 to perform injection molding operation on the molding mold; wherein a heating device is arranged in the barrel 711, so that the plastic melts and forms a molten state during the movement inside the barrel 711. At the same time, considering that when the molten plastic is injected into the molding mold from the injection nozzle 7112, a reverse thrust is generated due to the extrusion force between the molten plastic and the molding mold, and the reverse thrust causes the barrel 711 to move away from the molding mold, at this time, the plasticizing component 710 is exerted with a force toward the injection port by the injection component 730, and the reverse thrust is overcome by the force, so as to prevent the barrel 711 from moving away from the molding mold, and ensure that the injection nozzle 7112 of the barrel 711 and the injection port of the molding mold are always tightly engaged.

[0044] Specifically, the pre-plastic component 720 includes a rotating motor 721 and a first plate 722.

In this arrangement, the rotating motor 721 is used as a power source to drive the screw 720 to rotate, and the structure is simple and practical.

[0045] Specifically, the injection component 730 includes an injection cylinder 731, a second plate 732 and a third plate 733, wherein the second plate 732, the third plate 733 and the first plate 722 are arranged in sequence from top to bottom; the second plate 732 is fixedly connected to the injection displacement seat 310 through a support rod 734; the first plate 722 is slidably connected to the support rod 734; the injection cylinder 731 is installed on the second plate 732, and the driving end of the injection cylinder 731 is connected to the third plate 733, and the third plate 733 is fixedly connected to the second plate 732 through a plurality of connecting rods 735; the injection cylinder 731 is used to apply a force toward the glue inlet to the plasticized component 710. In this arrangement, the injection cylinder 731 installed on the second plate 732 applies a force to the third plate 733, so that the third plate 733 applies a force to the first plate 722 through the connecting rod 735. Since the rotating motor 721 is installed in the first plate 722, and the driving end of the rotating motor 721 is connected to the plasticizing component 710, the plasticizing component 710 is subjected to a force toward the glue inlet, so as to ensure the smooth implementation of the technical solution of this embodiment. The first plate 722 is slidably connected to the support rod 734, so that under the guidance of the support rod 734, the first plate 722 is ensured to move along the preset path.
