Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, and in particular to a quick-disassembly and assembly structure for a color mixing injection molding machine. Background Technology

[0002] Injection molding equipment is widely used in the production of plastic products. Its main function is to heat plastic raw materials to a molten state and inject them into a mold under high pressure for molding. A color-mixing injection molding machine is a type of injection molding machine designed to produce plastic products with complex colors or material properties by simultaneously injecting different colors or types of plastic materials. The injection unit structure of a color-mixing injection molding machine differs from that of a traditional single-injection injection molding machine, employing a dual-injection or multi-injection unit design to meet the needs of simultaneous injection of different colors or materials.

[0003] Two-color injection molding machines are common in the market, capable of injecting two materials simultaneously to meet the production needs of mixed-color products. Some dual-injector injection molding machines typically employ a fixed injection stage design, mainly including R-type dual-injector structures and back-mounted dual-injector structures. Traditional integrated dual-injector structures have a high degree of coupling between components and a more complex overall layout, increasing the machine's lateral footprint and making it difficult to adapt to compact production lines.

[0004] Furthermore, when it is necessary to disassemble the injection station or perform maintenance on critical components, it often requires disassembling more parts and making complex adjustments. In addition, injection stations with angled surfaces require additional angle adjustments during hoisting. Therefore, the disassembly and debugging process of the injection station is extremely cumbersome, and maintenance consumes a significant amount of time and manpower. Moreover, the maintenance and replacement of the injection cylinder or push rod, simply by pulling out the injection cylinder or push rod, requires at least a considerable amount of manpower and resources, and more than 3 hours of high-intensity work to complete.

[0005] On the other hand, designs such as the backpack-type dual-stage firing platform directly install the secondary firing platform on top of the main firing platform. This also presents problems such as unstable center of gravity, difficulty in disassembly, and safety hazards. In particular, when it is necessary to perform local maintenance on the main firing platform components located at the bottom, the maintenance process is extremely cumbersome, greatly increasing the downtime and maintenance costs of the equipment during production.

[0006] Therefore, there is an urgent need for a new dual-launcher design that can solve the above problems, especially providing better solutions in terms of ease of assembly and disassembly, weight management, and rapid structural development. Utility Model Content

[0023] Compared with the prior art, the beneficial effects of this utility model are at least in the following aspects:

[0024] 1. The color mixing machine spraying platform structure of this utility model adopts a standardized modular design. The first spraying platform module and the second spraying platform module can be pre-assembled as independent units. Through the support step and locking step cooperation structure, combined with the design of adjustable components such as threaded adjustment rod and adjustment slide rod, the second spraying platform module can be quickly disassembled or installed. There is no need to hoist the whole machine. It can be operated by only lifting or sliding a part, which greatly reduces the degree of manual intervention and hoisting complexity, improves maintenance efficiency by about 60%, and greatly shortens equipment downtime.

[0025] Furthermore, this utility model is equipped with adjustment components in multiple directions, so that the second injection stage can be precisely adjusted according to the actual working conditions after assembly, effectively compensating for equipment deviations and assembly errors, and ensuring the accurate consistency of the main and auxiliary injection stages in core parameters such as axis, levelness, and thrust direction, thereby improving color mixing consistency and improving the stability and yield of injection molding.

[0026] In addition, since each firing station module can be quickly and independently replaced, the equipment can be quickly disassembled for cleaning, modification or replacement when changing to different production needs, different colors or different types of plastics, which greatly improves the adaptability to diversified production.

[0027] 2. This utility model avoids the space occupation of traditional backpack-type and R-type injection platforms by installing the second injection platform module as a whole on one side of the first injection platform module at the same height. It achieves a compact arrangement of the longitudinal and transverse structures of the injection platform, reducing the overall space occupied by the equipment by about 30%, resulting in high space utilization and adaptability to different site layouts. At the same time, the first injection platform module adopts a standard stepped installation structure that can be used with the second module. After the second injection platform module is pre-assembled, it is hoisted onto the first injection platform as a whole. The first injection platform module itself also reduces the interlocking and restriction of internal components through its modular structure, making it easier to replace key components such as injection guide rods, injection push rods, and injection cylinders individually in case of failure. This minimizes the difficulty of assembling integrated components of the injection molding machine in the air and in narrow spaces, greatly reducing the operational burden on maintenance personnel.

[0028] 3. The launcher structure of this utility model adopts a modular design. The standard modular structure is not only suitable for the manufacturing of complete sets of equipment, which greatly improves production efficiency and reduces production difficulty; at the same time, it is also easier for maintenance personnel to quickly replace the module units in case of failure, further reducing downtime for maintenance, ensuring continuous operation of the equipment, and making the overall adaptability stronger.

The second injection front plate 21 and the second injection rear plate 22 are respectively adjustablely mounted on the corresponding first injection front plate 11 and the first injection rear plate 12 through the adjusting components 4.

[0039] The color mixing machine spraying platform structure of this utility model adopts a standardized modular design. Both the first and second spraying platform modules can be pre-assembled as independent units. Through the design of the adjustable components, the second spraying platform module can be quickly disassembled or installed. There is no need to hoist the whole machine as a whole. It can be operated by partial lifting or sliding, which greatly reduces the degree of manual intervention and hoisting complexity, improves maintenance efficiency by about 60%, and greatly shortens equipment downtime.

[0040] In addition, since each firing station module can be quickly and independently replaced, the equipment can be quickly disassembled for cleaning, modification or replacement when changing to different production needs, different colors or different types of plastics, which greatly improves the adaptability to diversified production.

[0041] Optionally, the adjustment assembly 4 includes a threaded adjustment rod 41 rotatably disposed on the support step 14, and the engaging step 24 is provided with an adjustment screw hole 241 adapted to the threaded adjustment rod 41; by adjusting the length of the threaded adjustment rod 41 extending into the adjustment screw hole 241, the installation position of the second injection front plate 21 and / or the second injection rear plate 22 can be adjusted.

[0042] Optionally, the support steps 14 of the first injection front plate 11 and / or the second injection rear plate 22 are provided with a plurality of mounting screw holes 141 adapted to the threaded adjusting rod 41. The threaded adjusting rod 41 can be selectively installed in different mounting screw holes 141 according to the different installation positions of the second injection front plate 21 and the second injection rear plate 22.

[0043] Optionally, the adjustment assembly 4 includes an adjustment slide rod 42 disposed between the first injection front plate 11 and the second injection front plate 21 and / or between the first injection rear plate 12 and the second injection rear plate 22; one end of the adjustment slide rod 42 is provided with a strip-shaped hole 421 extending along its length direction, and the second injection front plate 21 and the second injection rear plate 22 are respectively provided with locking holes 25 corresponding to the strip-shaped hole 421; by fasteners passing through different positions of the strip-shaped hole 421 and connecting with the locking holes 25, the relative positions between the second injection front plate 21 and the first injection front plate 11, and between the second injection rear plate 22 and the first injection rear plate 12 are respectively adjusted.

[0044] Furthermore, the adjusting slide bar 42 includes a horizontal adjusting slide bar 422 and a vertical adjusting slide bar 423; the horizontal adjusting slide bar 422 is disposed on the top of the first injection front plate 11 and the second injection front plate 21, and the end of it connected to the second injection front plate 21 is provided with the strip hole 421; the vertical adjusting slide bar 423 is disposed between the supporting step 14 and the engaging step 24, and the end of it connected to the engaging step 24 is provided with the strip hole 421; the second injection front plate 21 and the second injection rear plate 22 can adjust their installation positions along the extension direction of the strip hole 421 of the horizontal adjusting slide bar 422 and the vertical adjusting slide bar 423, respectively.

[0045] In this embodiment, multiple lateral and vertical adjustment slides are installed at the top of the first and second injection front plates, as well as between the support and locking steps. These slides, along with slotted holes and locking holes, allow the second injection stage module to be finely adjusted and fixed in both directions using fasteners. This design accommodates auxiliary injection stages of different specifications and assembly tolerances, enabling rapid alignment and multi-angle precision adjustment, thus improving the installation compatibility and flexibility of the main injection stage structure. The bidirectional adjustment capability further enhances the calibration accuracy of the injection axis, ensuring consistent injection paths and effectively guaranteeing color mixing consistency and injection molded product quality.

[0046] Optionally, two first injection guide rods 13 are diagonally spaced between the first injection front plate 11 and the first injection rear plate 12; two second injection guide rods 23 are diagonally spaced between the second injection front plate 21 and the second injection rear plate 22; the distance between the upper first injection guide rod 13 and the second injection guide rod 23 is smaller than the distance between the lower first injection guide rod 13 and the second injection guide rod 23.

[0047] A first guide plate 15 is slidably sleeved on the two first injection guide rods 13, and a second guide plate 26 corresponding to the first guide plate 15 is slidably sleeved on the two second injection guide rods 23. The distance between the first guide plate 15 and the second guide plate 26 gradually decreases upward.

[0048] The first injection rear plate 12 and the second injection rear plate 22 are respectively provided with a first injection cylinder 16 and a second injection cylinder 27 on their rear sides. The first injection cylinder 16 and the second injection cylinder 27 are respectively connected to the center of the first guide plate 15 and the second guide plate 26 through the first injection piston rod 161 and the second injection piston rod 271. In this embodiment, a diagonally arranged double guide rod structure is adopted, that is, two injection guide rods are respectively arranged along the diagonal direction between the first injection front plate and the second injection front plate and the second injection rear plate, and a sliding guide plate is set on the guide rod. This arrangement forms a stable triangular mechanical support structure, which can improve the structural stability and resistance to eccentric loads while reducing the number of guide rods compared with the traditional four-corner straight arrangement.

[0049] Optionally, the color mixing injection molding machine includes a melting module 5, which includes a first melting cylinder 51 and a second melting cylinder 52 respectively installed on the first injection front plate 11 and the second injection front plate 21; the inner cavities of the first melting cylinder 51 and the second melting cylinder 52 are respectively provided with a first injection push rod 53 and a second injection push rod 54; the first injection push rod 53 and the second injection push rod 54 respectively pass through the first injection front plate 11 and the second injection front plate 21, and are connected to the center of the corresponding first guide plate 15 and the second guide plate 26; the first injection push rod 53, the second injection push rod 54 and the first injection piston rod 161 and the second injection piston rod 271 are respectively connected to both sides of the first guide plate 15 and the second guide plate 26;

[0050] The first guide plate 15 and the second guide plate 26 are driven by the corresponding first injection piston rod 161 and second injection piston rod 271 to reciprocate along the first injection guide rod 13 and the second injection guide rod 23, thereby driving the first injection push rod 53 and the second injection push rod 54 to reciprocate.

[0051] To improve the installation efficiency of the first and second melt cylinders, the first injection front plate 11 and the second injection front plate 21 are respectively provided with melt cylinder mounting holes 6 for installing the first melt cylinder 51 and the second melt cylinder 52. At least one positioning pin 7 is radially protruding from the outer wall of the first melt cylinder 51 and the second melt cylinder 52. The inner wall of the melt cylinder mounting hole 6 of the first injection front plate 11 and the second injection front plate 21 is recessed with a positioning groove 61 that matches the positioning pin 7. The positioning groove 61 has a limiting part for limiting the positioning pin 7. This not only enables automatic guided insertion during installation, avoiding rotational misalignment, but also allows for axial limiting and locking of the melt cylinder through the limiting part, significantly improving installation efficiency and reducing manual adjustment time. Simultaneously, it facilitates the disassembly and replacement of the melt cylinders, improving the convenience of overall machine maintenance and the ease of modular replacement.

[0052] In this embodiment, the outer periphery of the melting cylinder is equipped with conventional heating components, such as heating coils and heating elements, providing continuous and stable heating during the injection molding process. When plastic granules are fed through the inlet, the injection pusher, driven by the guide plate, propels the material forward. As the material moves forward in the melting cylinder, it is gradually melted by the external heating coils, forming molten plastic. After the melting process is complete, the first and second injection cylinders at the rear end begin operation, driving the first and second injection piston rods forward. This, in turn, causes the guide plate and its injection pusher to move forward in a synchronized linear motion, ultimately injecting the molten plastic into the mold cavity through the nozzle module, completing one color mixing injection operation.

[0053] Optionally, the center of the first guide plate 15 and the second guide plate 26 is provided with a first assembly hole 151 and a second assembly hole 261 for installing the first injection piston rod 161 and the second injection piston rod 271, respectively; the first injection push rod 53 and the second injection push rod 54 are respectively installed on the other side of the corresponding first assembly hole 151 and the second assembly hole 261, and are coaxially arranged with the first injection piston rod 161 and the second injection piston rod 271; the two ends of the first guide plate 15 and the second guide plate 26 are respectively provided with a first guide hole 152 and a second guide hole 262 that are adapted to the first injection guide rod 13 and the second injection guide rod 23, respectively, and the center of each set of first guide holes 152 or second guide holes 262 and the center of the corresponding first assembly hole 151 or second assembly hole 261 are located on the same straight line.

[0054] In this embodiment, by setting an assembly hole coaxial with the injection piston rod at the center of the guide plate and setting guide holes at both ends to cooperate with the guide rod, the push rod, piston rod, and guide path are aligned on the same axis, forming a complete force-closed system. This structure not only improves the linear accuracy and stability of the injection action but also forms a three-point coaxial support, providing excellent structural mechanical stability. It can effectively resist interference from off-center loads and lateral forces, reduce motion resistance and component wear, and further ensure color mixing uniformity and injection molding accuracy.

[0055] Optionally, the support 3 includes a front support 31, a rear support 32, and a jetting guide rod connecting the front support 31 and the rear support 32; the top of the front support 31 and the rear support 32 are respectively provided with V-shaped openings, one side of the V-shaped openings corresponding to the support step 14; the two jetting guide rods slide through the bottom of the first injection front plate 11 and the first injection rear plate 12 respectively, and are respectively connected to both sides of the V-shaped openings of the front support 31 and the rear support 32.

[0056] Optionally, the color mixing injection molding machine further includes a nozzle module 8; the nozzle module 8 includes a first color mixing body 81, a second color mixing body 82, and a nozzle 83 communicating with the first color mixing body 81 and the second color mixing body 82; the first color mixing body 81 and the second color mixing body 82 are respectively provided with a first flow channel 811 and a second flow channel 821 communicating with the first melt cylinder 51 and the second melt cylinder 52; the first flow channel 811 and the second flow channel 821 extend into the nozzle 83, and the molten plastic flows through the first flow channel 811 and the second flow channel 821 respectively and is then injected into the mold from the end of the nozzle 83.

[0057] The working process of this utility model is as follows: First, plastic granules enter the melting cylinder through the feed port (not shown in the attached figure) of the first melting cylinder / second melting cylinder. Then, the first injection push rod / second injection push rod, driven by the first injection cylinder / second injection cylinder respectively, pushes the plastic granules forward. The plastic granules are melted into a liquid state under the heating of heating components such as electric heating coils and heating plates (not shown in the attached figure) on the outer periphery of the melting cylinder. After passing through the first color mixer / second color mixer, they pass through the first flow channel and the second flow channel respectively and are injected into the mold from the end of the nozzle.

[0058] It should be noted that this utility model also includes other components that meet the normal operation of the injection molding machine. This utility model does not make any improvements to these components, and all components in the prior art can be used. These components include a glue-passing shaft set at the outlet of the first melt cylinder / second melt cylinder, and a check structure set between the first color mixer and the second color mixer to achieve zero backflow mixing of multiple raw materials.
