Description

Technical Field

[0001] This utility model relates to a device suitable for rotary injection molding, and more specifically to a connecting device, specifically a connecting device for rotary injection molding. Background Technology

[0002] A gyrator is a novel two-port element, a type of two-port resistive element used in modern network theory. It can convert the input current at one port into the output voltage at the other port, or vice versa. Utilizing this property, a capacitor can be equivalently simulated as an inductor, and vice versa.

[0003] A gyroscope consumes no energy and does not store energy. It is a non-reciprocal element. From the voltage-current relationship of the gyroscope, it can be seen that the output voltage and input voltage are linear functions of the input current and output current, respectively.

[0004] The outer shell of the rotary device needs to be produced using injection molds, which requires the use of injection molds.

[0005] In industrial production, molds are various types of molds and tools used to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects; this tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of objects by changing the physical state of the material being molded. It is often referred to as the "mother of industry."

[0006] The rotary mold has four rotating surfaces for production and two front-to-back parting surfaces. This allows for simultaneous single production steps such as mold filling, cooling, or part removal, reducing cycle time by up to 30%. Further process steps, such as embedded assembly or quality assurance, can be integrated without extending cycle time. There are twice the number of cavities on the same mold mounting surface.

[0007] A typical plastic mold consists of two parts: a moving mold and a fixed mold. The moving mold is mounted on the moving platen of the injection molding machine, and the fixed mold is mounted on the fixed platen. During injection molding, the moving mold and the fixed mold close to form the gating system and the cavity. When the mold opens, the moving mold and the fixed mold separate to remove the plastic product.

[0008] However, existing injection molds cannot achieve synchronous operation of injection and unloading, i.e., they cannot achieve cyclic operation, resulting in low efficiency of the injection process. In addition, existing equipment is not convenient for synchronous pulling and rotating, causing inconvenience in using rotating molds. Utility Model Content

[0009] One objective of this invention is to provide a new technical solution for a connecting device for rotary injection molding.

[0010] According to a first aspect of the present invention, a connecting device for injection molding of a rotary device is provided, including a rotary mold, wherein injection grooves are provided on all four sides of the rotary mold;

[0011] The rotating mold has a rotating shaft fixedly installed at both the upper and lower ends. A gear mechanism is keyed to the lower rotating shaft. The gear mechanism includes a connecting ring fixedly connected to the rotating shaft. A support plate is integrally formed at the lower part of the connecting ring. A gear ring is movably installed on the support plate. A ratchet tooth is fixedly provided on the outer side of the connecting ring. A pawl is movably installed on the inner side of the gear ring.

[0012] Furthermore, a limiting ring is fixedly provided on the support plate, and a limiting groove is provided at the lower part of the gear ring, with the limiting ring movably located inside the limiting groove.

[0013] Furthermore, an installation groove is provided on the inner side of the gear ring, one end of the pawl is movably installed inside the installation groove via a connecting pin, one side of the pawl is movably installed with an elastic plate via a connecting pin, and the other end of the elastic plate is movably installed inside the installation groove via a connecting pin.

[0014] Furthermore, the upper end face of the gear ring is provided with a cover, and the cover is keyed to the rotating shaft.

[0015] Furthermore, positioning plates are movably mounted on the upper and lower rotating shafts respectively, and a connecting plate is fixedly provided at one end of the upper and lower positioning plates. Sliding blocks are movably connected to the ends of the upper and lower rotating shafts respectively.

[0016] Furthermore, sliding grooves are provided on both sides of the sliding block, and guide frames are sleeved on the outer sides of the upper and lower sliding blocks. Guide bars are fixedly provided on the inner side of the guide frames, and the guide bars are movably located inside the sliding grooves.

[0017] Furthermore, vertical plates are welded to the ends of the upper and lower guide frames, and a servo electric cylinder is fixedly installed on one side of the vertical plate. The telescopic end of the servo electric cylinder passes through the vertical plate and is fixedly connected to one side of the connecting plate.

[0018] Furthermore, a rack is fixedly provided on one side of the lower guide frame, and the rack meshes with the gear ring.

[0019] According to one embodiment of this disclosure, the present invention uses a rotary mold to perform injection molding production on a rotary press, which allows the rotary mold to perform injection molding, cooling, unloading and mold cleaning simultaneously during production, effectively improving the injection molding production efficiency of the rotary press.

[0020] The rotary mold is guided, limited, and installed by a guide frame, which facilitates the push-pull adjustment of the rotary mold. A rack is set on the lower guide frame to facilitate meshing with the gear mechanism on the rotating shaft. This allows the rotary mold to rotate when it is pushed or pulled, enabling simultaneous operation of injection molding, cooling, unloading, and mold cleaning, which can effectively improve the injection molding production efficiency of the rotary machine.

[0021] In order to prevent the gear mechanism from driving the rotating mold to rotate during the reset and fitting process, the gear mechanism is designed with a connecting ring and ratchet teeth. A pawl is set on the inner side of the gear ring. The locking connection between the pawl and the ratchet teeth makes it easy to drive the rotating mold to rotate when the gear ring and rack are engaged and pulled backward. The elastic plate pushes to make the pawl and ratchet teeth lock together. And when the rotating mold is reset, it will not drive the rotating mold to rotate.

[0036] like Figure 1-7 As shown, a connecting device for rotary injection molding includes a rotary mold 1, and injection grooves 2 are provided on all four sides of the rotary mold 1.

[0037] Rotary mold 1 has a rotating shaft 3 fixedly installed at its upper and lower ends respectively. A gear mechanism 8 is keyed to the lower rotating shaft 3. The gear mechanism 8 includes a connecting ring 804 fixedly connected to the rotating shaft 3. A support plate 801 is integrally formed at the lower part of the connecting ring 804. A gear ring 802 is movably installed on the support plate 801. A ratchet tooth 805 is fixedly provided on the outer side of the connecting ring 804. A pawl 807 is movably installed on the inner side of the gear ring 802.

[0038] In this embodiment, preferably, a limiting ring 809 is fixedly provided on the support plate 801, and a limiting groove 810 is provided at the lower part of the gear ring 802, with the limiting ring 809 movably located inside the limiting groove 810.

[0039] It should be noted that the combination of the limiting ring 809 of the support plate 801 and the limiting groove 810 of the gear ring 802 can maintain the stable connection of the gear ring 802 and prevent the gear ring 802 from shaking or falling off.

[0040] In this embodiment, preferably, the gear ring 802 has an installation groove 806 on its inner side, one end of the pawl 807 is movably installed inside the installation groove 806 by a connecting pin, one side of the pawl 807 is movably installed with an elastic piece 808 by a connecting pin, and the other end of the elastic piece 808 is movably installed inside the installation groove 806 by a connecting pin.

[0041] It should be noted that the mounting slot 806 is designed to enable the pawl 807 to be movably mounted, and the elastic plate 808 is designed to push the pawl 807, so that the pawl 807 can be stably locked between the ratchet teeth 805, which facilitates locking the ratchet teeth 805 and makes it easier to drive the rotating mold 1 to rotate.

[0042] In this embodiment, preferably, the upper end face of the gear ring 802 is provided with a cover 803, and the cover 803 is keyed to the rotating shaft 3;

[0043] It should be noted that the cover 803 provided on the upper part of the gear ring 802 facilitates the sealing of the internal ratchet teeth 805, pawls 807, etc., to achieve safety protection.

[0044] In this embodiment, preferably, positioning plates 4 are movably installed on the upper and lower rotating shafts 3 respectively, a connecting plate 5 is fixedly provided at one end of the upper and lower positioning plates 4, and a sliding block 6 is movably connected to the ends of the upper and lower rotating shafts 3 respectively.

[0045] It should be noted that the positioning plate 4 and the connecting plate 5 are designed to position and install the rotating mold 1 to maintain stability.

[0046] In this embodiment, preferably, sliding grooves 7 are provided on both sides of the sliding block 6, and guide frames 9 are sleeved on the outer sides of the upper and lower sliding blocks 6. Guide strips 10 are fixedly provided on the inner side of the guide frames 9, and the guide strips 10 are movably located inside the sliding grooves 7.

[0047] It should be noted that the sliding groove 7 allows the sliding block 6 to slide inside the guide frame 9, maintaining stability and mobility.

[0048] In this embodiment, preferably, vertical plates 12 are welded to the ends of the upper and lower guide frames 9, and a servo electric cylinder 13 is fixedly installed on one side of the vertical plate 12. The telescopic end of the servo electric cylinder 13 passes through the vertical plate 12 and is fixedly connected to one side of the connecting plate 5.

[0049] It should be noted that the upper and lower guide frames 9 are connected and installed through a vertical plate 12, and the power is output through a servo electric cylinder 13, which also enables the push-pull adjustment of the connecting plate 5.

[0050] In this embodiment, preferably, a rack 11 is fixedly provided on one side of the lower guide frame 9, and the rack 11 is meshed with the gear ring 802;

[0051] It should be noted that the rack 11 is designed to mesh with the gear ring 802, so that the rotating mold 1 can rotate and adjust accordingly when it is pushed and pulled.

[0052] The specific operational procedures for this application are as follows:

[0053] During use, the vertical plate 12 and guide frame 9 are used for positioning and installation, and the servo electric cylinder 13 is used to push and pull the rotating mold 1 for adjustment.

[0054] In use, the connecting plate 5 is pulled by the servo electric cylinder 13, and the connecting plate 5 is connected to the rotating shaft 3 at both ends of the rotating mold 1 through the upper and lower positioning plates 4, and the rotating mold 1 is connected to it, so that the servo electric cylinder 13 can push and pull the rotating mold 1 for adjustment. In order to move the rotating mold 1, the sliding block 6 is movably installed at both ends of the rotating shaft 3, and the sliding block 6 cooperates with the guide strip 10 inside the guide frame 9 through the sliding groove 7 to maintain the stability of the sliding block 6 within the guide frame 9 for movement adjustment.

[0055] Then, when the servo electric cylinder 13 pulls the connecting plate 5 and the rotating mold 1, the gear ring 802 in the gear mechanism 8 meshes with the rack 11, causing the gear ring 802 to rotate. When the gear ring 802 rotates, the ratchet teeth 805 on the connecting ring 804 are locked by the inner pawl 807, which facilitates the rotation of the ratchet teeth 805 and the connecting ring 804, thereby driving the rotating mold 1 to rotate. This allows the rotating mold 1 to achieve simultaneous operation of injection molding, cooling, unloading, and mold cleaning, effectively improving the injection molding production efficiency of the rotary machine. Furthermore, the elastic plate 808 pushes the pawl 807, allowing the pawl 807 to be locked between the ratchet teeth 805.

[0056] When the servo electric cylinder 13 pushes the connecting plate 5 and the rotary mold 1, the pawl 807 is pushed by the ratchet tooth 805, so that the pawl 807 will not lock the ratchet tooth 805. At this time, the transmission of the meshing connection between the rack 11 and the gear ring 802 will not drive the connecting plate 5 and the ratchet tooth 805 to rotate, and thus will not drive the rotary mold 1 to rotate. This allows the rotary mold 1 to achieve continuous clockwise rotation, which facilitates the synchronous operation of injection molding, cooling, unloading and mold cleaning, and can effectively improve the injection molding production efficiency of the rotary machine.
