Description

Technical Field

[0001] This utility model relates to the field of foaming mold technology, specifically to a synchronous opening and closing device for a multi-cavity foaming mold. Background Technology

[0002] The synchronous opening and closing device of a multi-cavity foaming mold is a key mechanism for realizing the synchronous opening or closing of multiple cavities of the mold. It transmits power evenly to the opening and closing units of each cavity through mechanical linkage, hydraulic / pneumatic synchronization or electromechanical servo, forcing each unit to maintain consistent action. This device can ensure that each cavity completes the opening and closing action in the same time, ensuring that the process conditions such as raw material filling, foaming reaction, cooling and shaping are consistent.

[0003] In the existing technology, the existing synchronous opening and closing device lacks an effective constraint structure. When it is raised, it is easy to cause the multi-module cavity to shake or shift. Moreover, it lacks auxiliary positioning function, which leads to critical deviations in the position of each cavity. For example, the gap between adjacent cavities becomes larger or misaligned. This will cause uneven material injection volume and speed, material accumulation in some cavities and insufficient filling in others, resulting in deviations in product dimensional accuracy and density distribution, which seriously affects consistency and pass rate. Utility Model Content

[0004] The purpose of this invention is to provide a synchronous opening and closing device for a multi-cavity foaming mold, in order to solve the problems mentioned in the background art. The existing synchronous opening and closing device tends to move multiple module cavities when it is raised, and lacks the function of auxiliary positioning of the cavities, which will cause the position of each cavity to deviate. This will not only cause uneven filling of raw materials and affect the product molding quality, but may also cause mold wear due to cavity misalignment, shorten the service life of the equipment, and increase maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a synchronous opening and closing device for a multi-cavity foaming mold, comprising a base frame and placement grooves on the left and right sides inside the base frame. Two cavities are movably connected inside the placement grooves. A positioning groove is provided at the top of the base frame, and a partition is connected inside the positioning groove.

A gear is connected to the bottom of the rotating plate extending to the lower end of the partition. A motor is connected to the rear end of the base frame. The positioning groove... The part is rotatably connected to a worm gear, which is connected to the output end of the motor. The worm gear meshes with a gear. A positioning plate is movably connected inside the arc groove. The positioning plate is slidably connected to the positioning groove and movably connected to the cavity. When the cavity is placed into the bottom frame, the motor drives the worm gear to rotate. The rotation of the worm gear drives the gear to rotate. The gear drives the rotating plate to rotate on the partition. The rotation of the rotating plate drives the arc groove to rotate. The rotation of the arc groove pushes the positioning plate to slide in the positioning groove until it fits against the cavity. When opening and closing, the motor drives the worm gear to rotate, making the positioning plate fit more tightly against the cavity.

[0006] Based on the preferred embodiment of this technical solution, the bottom frame is internally connected to a breathable plate, the left and right ends of the bottom frame are connected to interfaces, and a medium groove is provided on the lower inner side of the bottom frame.

[0008] In the preferred embodiment of this technical solution, a handle is connected to the top of the cover plate, a support rod is connected to the bottom of the auxiliary block, and an electric lifting rod drives the cover plate to move vertically.

[0009] Based on the preferred embodiment of this technical solution, grasping the handle causes the cover plate to rotate, and the cover plate is movably connected to the bottom frame.

[0010] Based on the preferred embodiment of this technical solution, after the cover plate is rotated to align with the corner of the bottom frame, the electric lifting rod drives the cover plate to descend, so that the cover plate fits against the bottom frame.

[0011] In this preferred embodiment of the technical solution, the support rod supports the bottom frame, the interface connects to an external pipe to transport the medium into the medium tank, the vent plate does not obstruct heat transfer, and the heating plate heats the medium to rapidly foam the material inside the cavity. Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a placement slot, cavity, positioning slot, rotating plate, arc groove, and motor-driven worm gear, the positioning plate in the arc groove slides and connects to the cavity, realizing real-time positioning and limiting to prevent displacement when lifting. After the cavity is placed, the motor drives the components to make the positioning plate fit tightly against the cavity. The fit is even tighter when opening and closing. This ensures the cavity is accurate, the raw material is filled stably and evenly, significantly improves the product qualification rate, reduces mold wear caused by displacement, greatly extends the life of the device, effectively reduces maintenance and production costs, and ensures efficient and stable production.

[0015] Please see Figure 1-5This utility model provides an embodiment of a synchronous opening and closing device for a multi-cavity foaming mold, including a base frame 1 and placement grooves 21 on the left and right sides inside the base frame 1.

After the cavity 22 is placed in, the motor 28 drives the worm gear 29 and gear 27 to rotate the rotating plate 25, and the arc groove 26 pushes the positioning plate 210 to fit tightly against the cavity 22. When opening and closing, the motor 28 drives the fit to be tighter, ensuring the cavity 22 is accurate, the material filling is stable, the pass rate is improved, wear is reduced, life is extended, and costs are reduced.

[0016] Please see Figure 2-5 A further solution based on this embodiment is as follows: a breathable plate 31 is connected inside the bottom frame 1, and interfaces 32 are connected to the left and right ends of the bottom frame 1. A medium groove 33 is opened on the lower inside of the bottom frame 1. The breathable plate 31 can support the wall without hindering heat transfer. The interface 32 is connected to an external pipe to transport the medium to the medium groove 33, which can provide the cavity 22 with the required heating medium and ensure the smooth progress of the foaming process.

[0017] Please see Figure 1-5A further solution based on this embodiment is as follows: a heating plate 34 is connected to the bottom of the bottom frame 1, and auxiliary blocks 35 are connected to the four corners of the bottom frame 1. An electric lifting rod 36 is connected inside the auxiliary block 35, and a cover plate 37 is connected to the top of the electric lifting rod 36 through a damping rotation. The heating plate 34 can heat the medium in the medium tank 33 to provide a suitable temperature for foaming and accelerate the foaming of the material. The electric lifting rod 36 on the auxiliary block 35 can drive the cover plate 37 to rise and fall. The damping rotation connection allows the cover plate 37 to rotate flexibly, which is convenient for opening and closing operations.

[0018] Please see Figure 1-5 A further solution based on this embodiment is as follows: a handle 38 is connected to the top of the cover plate 37, a support rod 39 is connected to the bottom of the auxiliary block 35, an electric lifting rod 36 drives the cover plate 37 to move vertically, the handle 38 makes it convenient for the operator to grab and rotate the cover plate 37, improving the ease of operation, the support rod 39 enhances the stability of the bottom frame 1 and prevents the device from shaking when it is working, and the electric lifting rod 36 drives the cover plate 37 to move vertically, ensuring the accuracy of opening and closing of the cover plate 37.

[0019] Please see Figure 1-5 A further solution based on this embodiment is as follows: Grasp the handle 38 to rotate the cover plate 37. The cover plate 37 is movably connected to the bottom frame 1. By rotating the cover plate 37 through the handle 38, the position of the cover plate 37 can be flexibly adjusted, making it convenient to take out or put in the cavity 22 or observe the internal situation. The operation is simple and efficient.

[0020] Please see Figure 1-5 A further solution based on this embodiment is as follows: After the cover plate 37 is rotated to align with the corner of the bottom frame 1, the electric lifting rod 36 drives the cover plate 37 to descend, so that the cover plate 37 fits with the bottom frame 1. After the cover plate 37 is aligned with the corner of the bottom frame 1, it descends and fits, which can form a good seal, reduce heat and medium loss, ensure the stability of the foaming environment in the cavity 22, and improve the foaming quality.

[0021] Please see Figure 1-5 A further solution based on this embodiment is as follows: the support rod 39 is used to support the bottom frame 1, the interface 32 is connected to the external pipe to transport the medium to the medium tank 33, the vent plate 31 does not obstruct heat transfer, the heating plate 34 is used to heat the medium to make the material in the cavity 22 foam quickly, the support rod 39 stably supports the bottom frame 1 to ensure the overall structure of the device is stable, the vent plate 31 does not obstruct heat transfer, and in conjunction with the heating plate 34 to heat the medium, it can quickly increase the temperature of the cavity 22, accelerate the foaming of the material, and improve production efficiency.

[0022] Working principle: When the synchronous opening and closing device of the multi-cavity foaming mold is working, the cavity 22 is first placed into the placement slots 21 on the left and right sides inside the bottom frame 1. At this time, the motor 28 at the rear end of the bottom frame 1 starts, driving the worm gear 29 in the positioning slot 23 to rotate. The worm gear 29 meshes with the gear 27 at the bottom of the rotating plate 25, thereby driving the rotating plate 25 to rotate on the partition plate 24. The staggered arc grooves 26 on the top of the rotating plate 25 rotate accordingly, pushing the internal positioning plate 210 to slide in the positioning slot 23 until it is tightly fitted with the cavity 22, achieving precise positioning of the cavity 22 and preventing it from shifting in the subsequent process. Afterwards, the operator uses the handle 38 on the top of the cover plate 37 and the damping rotation structure on the top of the electric lifting rod 36 on the auxiliary block 35 to rotate the cover plate 37 until it is aligned with the corner of the bottom frame 1. The electric lifting rod 36 then drives the cover plate 37 to rotate. 7. The device descends vertically to fit tightly against the bottom frame 1, forming a sealed environment. Simultaneously, the interface 32 connects to an external pipe, delivering the foaming medium to the medium tank 33 on the lower side of the bottom frame 1. The heating plate 34 at the bottom of the bottom frame 1 heats the medium in the medium tank 33. The heat is transferred to the cavity 22 through the breathable plate 31, which does not obstruct heat transfer, providing a suitable temperature for the foaming of the material in the cavity 22 and accelerating the foaming process. Meanwhile, the support rod 39 at the bottom of the auxiliary block 35 provides stable support for the bottom frame 1, ensuring the overall stable operation of the device. When the device needs to be opened or closed, the motor 28 drives the worm gear 29 to rotate again, making the positioning plate 210 fit more tightly against the cavity 22, ensuring that the cover plate 37 will not shift during the opening and closing process. To remove or place the cavity 22 or observe the interior, the cover plate 37 can be rotated by the handle 38, making the operation convenient and efficient.
