Description

Technical Field

[0001] This utility model relates to the field of plastic molding technology, and in particular to a multi-station injection device and an injection molding machine. Background Technology

[0002] Injection molding machines are molding devices that inject molten plastic into molds to create plastic products of various shapes. Most injection molding machines used today are horizontal. To accommodate horizontal injection molding machines, the injection gates of most molds are horizontally positioned. For two-color / two-material plastic products, two single-color injection molding machines are typically used to inject the material one color at a time, resulting in relatively high production costs. Although V-shaped two-color injection molding machines exist, these are expensive and cannot be used in conjunction with single-color injection molding machines, leading to low equipment utilization and hindering cost reduction. Furthermore, regardless of whether two single-color injection molding machines are used for injection or a V-shaped two-color injection molding machine is used, its horizontal placement within the mold area results in a high occupancy rate of the injection molding machine, increasing the company's space investment costs.

[0003] In order to produce two-color / two-material plastic products more efficiently and reduce the floor space occupancy of injection molding machines, some manufacturers have developed molding dies with a gate on the top side. Two different plastic materials are injected into the molding die through the gate on the top side to produce two-color / two-material plastic products. Since the gate is located on the top side, the injection device needs to be installed in the upper area of ​​the molding die, thereby reducing the floor space occupancy of the injection molding machine.

[0004] Therefore, there is an urgent need for a top-side injection device that can be applied to molding dies with a gate on the top side. On the one hand, it can be adjusted in multiple directions to match molding dies of different specifications, thereby improving the compatibility of the injection device; on the other hand, it can reduce the floor space occupancy of the injection molding machine, thereby helping to reduce the site investment costs of enterprises.

[0005] It should be noted that the above content is only used to help understand the technical solution of this utility model, and does not represent an admission that the above content is prior art. Utility Model Content

[0007] To achieve the above objectives, this utility model proposes a top-side multi-station injection device for use in injection molding machines. The injection molding machine includes a template for mounting a molding die, wherein the molding die has a glue inlet on the top side.

[0008] The multi-station injection device is characterized in that it comprises:

[0009] Mounting base, the mounting base is located on the top side of the template;

[0010] A first injection mechanism and a second injection mechanism are both mounted on the mounting base, and the first injection mechanism and the second injection mechanism inject adhesive into the glue inlet;

[0013] In one embodiment, the multi-station injection device on the top side is characterized in that the first injection mechanism and the second injection mechanism include an injection assembly, a mounting plate, a support frame, and an injection transfer seat. The mounting plate slides along the first linear guide rail. The injection assembly and the injection transfer seat are mounted on the support frame. The support frame is mounted on the mounting plate. The mounting plate is provided with a second linear guide rail. The support frame can move along the second linear guide rail in the X-axis direction.

[0014] In one embodiment, the injection assembly is mounted in the injection transfer seat, the injection transfer seat is mounted on the support frame, the support frame is provided with a third linear guide rail, and the injection transfer seat can move along the third linear guide rail in the Z-axis direction.

[0015] In one embodiment, the mounting base is provided with a lead screw drive device, which drives the first injection mechanism and the second injection mechanism to move along the first linear guide rail. The lead screw drive device includes two sets of transmission lead screws, which are respectively connected to the mounting plates of the first injection mechanism and the second injection mechanism.

[0020] To achieve the above objectives, this utility model proposes an injection molding machine, which includes the top-side multi-station injection device described in any of the above claims.

[0021] The technical solution of this utility model involves setting a mounting base on the top side of the injection molding machine's mold platen, and mounting a first injection mechanism and a second injection mechanism on the mounting base.

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0037] To achieve more efficient production of two-color / two-material plastic products and reduce the floor space occupancy of injection molding machines, some manufacturers have developed molds with injection ports on the top side. Two different plastic materials are injected into the mold through these top-side ports to produce two-color / two-material plastic products. Since the injection ports are located on the top side, the injection unit needs to be installed above the mold, further reducing the floor space occupancy of the injection molding machine. Therefore, there is an urgent need for a top-side injection unit that can be used with molds having injection ports on the top side. This unit should allow for multi-directional adjustment to accommodate different mold sizes, improving the compatibility of the injection unit; and it should also reduce the floor space occupancy of the injection molding machine, thereby reducing the company's site investment costs.

[0038] To solve the above-mentioned technical problems, this utility model proposes a multi-station injection device for the top side.

[0039] Please see Figure 1 In one embodiment of the present invention, the top-side multi-station injection device is applied to an injection molding machine, which includes a template 100 (not shown in the figure) for mounting a molding die, wherein the molding die is provided with a glue inlet (not shown in the figure) on the top side.

[0040] Specifically, the multi-station injection device on the top side includes:

[0041] Mounting base 200 is positioned on the top side of template 100;

[0042] The first injection mechanism 300 and the second injection mechanism 400 are both mounted on the mounting base 200. The first injection mechanism 300 and the second injection mechanism 400 inject adhesive into the glue inlet.

[0043] The distance between the first injection mechanism 300 and the second injection mechanism 400 is adjustable in the X-axis direction and / or the Y-axis direction and / or the Z-axis direction.

[0044] The technical solution of this utility model involves setting a mounting base 200 on the top side of the mold plate 100 of an injection molding machine, and mounting the first injection mechanism 300 and the second injection mechanism 400 on the mounting base 200. The first injection mechanism 300 and the second injection mechanism 400 inject rubber material into the sprue, thereby achieving injection molding of the mold with a sprue on the top side. Simultaneously, the distance between the first injection mechanism 300 and the second injection mechanism 400 is adjustable in the X-axis and / or Y-axis and / or Z-axis directions, allowing the first injection mechanism 300 and the second injection mechanism 400 to connect with the sprue on the top side through multi-dimensional movement. This allows for multi-directional adjustment to accommodate molds of different specifications, thereby improving the compatibility of the injection device. Furthermore, since the first injection mechanism 300 and the second injection mechanism 400 are mounted on the top side of the mold plate 100, i.e., the area above the mold, the planar space occupancy rate of the injection molding machine is reduced, which helps to reduce the company's site investment costs.

[0045] Since the first injection mechanism 300 and the second injection mechanism 400 each carry different types of plastic materials, such as one material being red and the other blue, the first injection mechanism 300 and the second injection mechanism 400 sequentially inject the materials into the inlet to produce two-color / two-material plastic products. In other embodiments, there may also be two inlets, with the first injection mechanism 300 and the second injection mechanism 400 corresponding one-to-one with the two inlets.

[0046] Specifically, see the attached document. Figure 4 The mounting base 200 has a first linear guide rail 210 in the Y-axis direction. The first injection mechanism 300 and the second injection mechanism 400 are slidably mounted on the first linear guide rail 210. The first injection mechanism 300 is closer to or farther away from the second injection mechanism 400 in the Y-axis direction. This arrangement simplifies the design structure in the Y-axis displacement by having the first injection mechanism 300 and the second injection mechanism 400 share the first linear guide rail 210, thereby reducing design complexity.

[0047] Specifically, see the attached document. Figure 2-3The first injection mechanism 300 and the second injection mechanism 400 include an injection assembly 310, a mounting plate 320, a support frame 330, and an injection transfer seat 340. The mounting plate 320 slides along the first linear guide rail 210. The injection assembly 310 and the injection transfer seat 340 are mounted on the support frame 330. The support frame 330 is mounted on the mounting plate 320. The mounting plate 320 is provided with a second linear guide rail 350. The support frame 330 can move along the second linear guide rail 350 in the X-axis direction. With this configuration, the mounting plate 320 is slidably connected to the first linear guide rail 210 to achieve displacement of the mounting plate 320 along the Y-axis direction; then, the support frame 330, on which the injection assembly 310 and the injection transfer seat 340 are mounted, is slidably connected to the second linear guide rail 350 to achieve displacement of the support frame 330 along the X-axis direction; since the second linear guide rail 350 is mounted on the mounting plate 320, the two together achieve displacement of the injection assembly 310 along the X-axis and Y-axis directions, resulting in a simple structure and strong practicality.

[0048] Specifically, the injection assembly 310 is installed in the injection transfer seat 340, which is mounted on a support frame 330. The support frame 330 is equipped with a third linear guide rail 360, allowing the injection transfer seat 340 to move along the third linear guide rail 360 in the Z-axis direction. This configuration allows the injection transfer seat 340 to be slidably connected to the third linear guide rail 360, thus enabling displacement of the injection transfer seat 340 along the Z-axis. Since the third linear guide rail 360 is mounted on the support frame 330, displacement of the injection assembly 310 along the Z-axis is achieved, resulting in a simple and practical structure.

[0049] The injection assembly 310 is used to inject molten rubber into the injection port; since the injection assembly 310 is prior art, its structure will not be described in detail here. In this embodiment, refer to the attached... Figure 5 The injection assembly 310 includes a barrel 311 and a screw 312 rotatably disposed inside the barrel 311. The side of the barrel 311 is provided with a feed hole 315 for feeding the rubber material. The end of the barrel 311 facing the feed hole is provided with a nozzle 313. The end of the barrel 311 away from the feed hole is provided with a rotary motor 314. The rotary motor 314 is used to drive the screw 312 to rotate, so that the rubber material is moved to the nozzle 313 under the push of the screw 312 to perform injection molding on the mold.

[0050] As a preferred embodiment of the above embodiments, refer to the appendix. Figure 2-3A first drive cylinder 370 is provided on the mounting plate 320. The piston rod of the first drive cylinder 370 is connected to the support frame 330, and the first drive cylinder 370 drives the support frame 330 to move along the second linear guide rail 350. This configuration utilizes the first drive cylinder 370 as a power source to drive the support frame 330, resulting in a simple structure and strong practicality. It is understood that those skilled in the art, based on their understanding of the technical solution of this embodiment, can conceive of other drive structures besides the first drive cylinder 370 without creative effort, and these should also fall within the scope of protection of this application.

[0051] As a preferred embodiment of the above embodiments, refer to the appendix. Figure 2-3 A second drive cylinder 380 is mounted on the support frame 330. The piston rod of the second drive cylinder 380 is connected to the injection seat 340, and the second drive cylinder 380 drives the injection seat 340 to move along the third linear guide rail 360. This configuration utilizes the second drive cylinder 380 as a power source to drive the injection seat 340, resulting in a simple structure and strong practicality. It is understood that those skilled in the art, based on their understanding of the technical solution of this embodiment, can conceive of other drive structures besides the second drive cylinder 380 without creative effort, and these should also fall within the scope of protection of this application.

[0052] Furthermore, electronic rulers (not shown in the attached figures) are respectively provided on the second linear guide rail 350 of the mounting plate 320 and the third linear guide rail 360 of the support frame 330. With this configuration, the electronic rulers are used to set the moving distance of the support frame 330 along the second linear guide rail 350 and the moving distance of the injection displacement seat 340 along the third linear guide rail 360, and then the first drive cylinder 370 and the second drive cylinder 380 are precisely controlled by their moving distances, thereby improving the displacement accuracy of the injection assembly 310 in the X-axis and Z-axis directions.

[0053] As a preferred embodiment of the above embodiments, refer to the appendix. Figure 4A lead screw drive device 220 is provided on the mounting base 200. The lead screw drive device 220 drives the first injection mechanism 300 and the second injection mechanism 400 to move along the first linear guide rail 210. The lead screw drive device 220 includes two sets of transmission lead screws 221, which are respectively connected to the mounting plates 320 of the first injection mechanism 300 and the second injection mechanism 400. Understandably, one set of transmission lead screws 221 is connected to the mounting plate 320 of the first injection mechanism 300 to drive the mounting plate 320 of the first injection mechanism 300 to move along the first linear guide rail 210; the other set of transmission lead screws 221 is connected to the mounting plate 320 of the second injection mechanism 400 to drive the mounting plate 320 of the second injection mechanism 400 to move along the second linear guide rail 350. With this configuration, since the displacement drive of the support frame 330 and the injection seat 340 mentioned above is driven and controlled by the first drive cylinder 370 and the second drive cylinder 380 respectively, there are certain requirements for the layout of the hydraulic oil circuit; therefore, the mounting plate 320 is driven and controlled by the screw drive device 220, which can save the layout of the hydraulic oil circuit and save costs.

[0054] Furthermore, the lead screw drive device 220 also includes a handwheel 222, which drives the transmission lead screw 221 to move. This configuration allows the operator to manually rotate the lead screw by turning the handwheel 222, which is simple and quick.
