Description

Technical Field

[0001] This invention relates to the field of molding die technology, and more specifically, to an energy flexible coupling mechanism for molding dies. Background Technology

[0002] In the field of mold forming and processing such as injection molding, die casting, and compression molding, the mold and forming equipment need to rely on water, oil, air, and electrical circuits to complete multiple energy transmission operations such as cooling, hydraulic drive, pneumatic control, and power supply. The reliability, convenience, and stability of energy connection directly determine the mold forming quality, equipment operating efficiency, and production line operation safety. At present, the industry generally adopts a split-type independent connection structure, with water, oil, air, and electricity pipelines connected separately and individually. This is the mainstream application form of mold energy connection at present.

[0003] Existing installation methods typically involve manually connecting each circuit individually, including pipes, switches, and connectors. When a single energy source has multiple circuits, due to the integrated nature of the energy source, connecting these circuits manually by locating and locking them is extremely demanding on the operator's skills. This method is not only time-consuming and inefficient, but also significantly increases the error rate when there are multiple circuits, making inspection difficult. Leaks at the connection points can easily lead to safety accidents. While it can achieve centralized connection of a single energy type, improving fault tolerance and work efficiency to some extent, it still needs further improvement in today's lean manufacturing environment. In particular, when a single circuit exceeds 20 lines and the pipe diameter is greater than 1 / 4 inch, the installation process becomes very strenuous due to the weight, significantly increasing the overall time consumption and corresponding safety hazards.

[0004] In view of this, we propose an energy flexible coupling mechanism for forming molds. Summary of the Invention

[0020] By adopting the above technical solution, the cleaning component can actively remove foreign objects that are easily stuck.

[0021] Beneficial effects: One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. By integrating four types of connection joints for water, oil, gas, and electricity, the synchronous connection of various pipelines and lines between the mold and the molding equipment can be completed in one go, eliminating the cumbersome process of separate connection. The overall assembly structure is neat and compact, and the installation, debugging and operation are simple and convenient. It can adapt to the energy transmission requirements of different specifications of molding molds and can meet the needs of various molding processes such as injection molding, die casting and compression molding. The equipment compatibility and practical application coverage are greatly improved.

[0022] 2. In the standby retracted state, the telescopic dust cover, together with the port magnetic sealing ring, tightly surrounds the transmission area, forming a complete closed protective cavity. This can completely block harmful impurities such as metal shavings, dust, and cutting oil from entering the internal structure, effectively preventing the accumulation of impurities that could cause parts to rust or movement to become stuck. This significantly reduces the failure rate in harsh production environments and ensures the stable operation of the mechanism.

[0023] 3. By relying on the telescopic action of the mechanism to compress the oil storage cavity, the T-screw can automatically spray oil for lubrication on demand, eliminating the need for manual periodic grease replenishment. This saves time and effort in maintenance. Furthermore, the lubricating grease is sealed and stored by a dust cover, preventing leakage and contamination of the mold cavity and molded products, thus ensuring product appearance and quality. At the same time, the lubricating oil can buffer the friction of the self-locking structure, effectively preventing thread jamming and excessive wear of parts. This significantly extends the service life of the drive transmission components and self-locking limit components, reduces the frequency of parts replacement, and effectively lowers the later maintenance and repair costs of the molding mold.

[0024] 4. The tapered guide with multi-directional floating compensation structure can autonomously correct coaxiality offset errors caused by assembly and operation. Even if there is an initial alignment deviation, it can automatically center and calibrate during movement through the multi-directional floating compensation structure to ensure precise alignment of the joint. The inner wall of the positioning guide sleeve is inlaid with wear-resistant ceramic anti-scratch plates. During the eccentric insertion process, only the protective parts bear the friction impact, effectively protecting the base structure from scratches and bumps. This not only improves the fault tolerance of docking but also stabilizes the positioning benchmark, ensuring that the docking position is consistent and standardized every time.

[0025] 5. During the floating deflection process of the substrate, the built-in air storage bag can be squeezed simultaneously. Compressed air is ejected from the inclined guide channel through the one-way valve and the manifold, forming a high-intensity swirling air field. This washes away residual debris and foreign objects in the floating mating gaps, actively removes easily obstructed foreign objects, improves the cleanliness of the mating surface, and avoids debris from getting stuck and affecting the floating compensation effect during the energy docking process of the mold, thus preventing docking deviations. At the same time, it can also effectively prevent debris from scratching the multi-directional floating compensation structure during the docking process, thereby affecting the docking accuracy. This effectively improves the positioning and docking effect of the molding mold during the energy docking process.

[0026] 6. The joint end face adopts a double-layer composite sealing structure of fluororubber and polytetrafluoroethylene. The inner fluororubber has excellent elastic deformation ability, which can adaptively fill the fine gaps and deformation gaps of the end face and firmly press the sealing interface; the outer PTFE material is oil and corrosion resistant and has a low coefficient of friction. It can resist the corrosion and erosion of various transport media and prevent the sealing surface from sticking and wearing out at high temperatures. The dual protection works together to maintain the sealing performance of the pipeline connection for a long time and effectively avoid safety hazards such as water leakage, oil leakage, gas leakage, and electric leakage after the molding mold is connected to the energy source.

[0027] 7. After docking, the elastic locking structure automatically engages and locks the T-screw rotation state, forming a mechanical rigid limit constraint. Even if the hydraulic system suddenly loses pressure or the equipment unexpectedly loses power during production, the mechanism position can be firmly locked to prevent the joint from loosening and separating in the opposite direction. The locking structure has adaptability and fault tolerance, and minor positional deviations will not damage the sealing performance, greatly improving the stability and safety of the energy docking operation of the molding mold.

An exhaust one-way valve 223 is disposed between the manifold 222 and the air storage bladders 221. Two oblique guide grooves 224 are provided on the inner wall of the manifold 222. A plurality of air inlets 225 are provided on the side of the moving base plate 134 near the fixed base plate 101. An air inlet one-way valve 226 is disposed inside the air inlet 225. The manifold 222 is connected to the interior of the air reservoir 221, the air inlet 225 is connected to the interior of the air reservoir 221, the oblique guide channel 224 extends through the inner wall of the movable base plate 134 to the side of the movable base plate 134 near the bridge plate 131, the end of the oblique guide channel 224 away from the manifold 222 is located on the side of the bridge plate 131, and the end of the air inlet 225 away from the air reservoir 221 is located on the side of the movable floating rod 14. During the floating deflection process of the substrate, the built-in air storage bag 221 can be squeezed simultaneously. Compressed air is ejected from the inclined guide channel 224 through the one-way valve and the manifold 222, forming a high-intensity swirling air field. This washes away residual debris and foreign objects in the floating mating gaps, actively removes easily stuck foreign objects, improves the cleanliness of the mating surface, and avoids the situation where debris gets stuck and affects the floating compensation effect during the energy docking process of the mold, causing the docking deviation to occur. At the same time, it can also effectively prevent the multi-directional floating compensation structure from being scratched by debris during the docking process, thereby affecting the docking accuracy. This effectively improves the positioning and docking efficiency of the molding mold during the energy docking process.

[0052] This invention provides an energy flexible coupling mechanism for molding dies, the working principle and usage process of which are as follows: First, the fixed bracket 102 is installed on the mold to be formed, and the fixed base plate 101 is installed on the fixed bracket 102, integrating a corresponding number of water connectors 103, oil connectors 104, air connectors 105, and electrical connectors 106, which are connected to the corresponding pipes and lines on the mold. Simultaneously, the mounting bracket 111 is installed on the forming equipment, and the water connectors 135, oil connectors 136, air connectors 137, and electrical connectors 138 on the moving base plate 134 are also connected to the corresponding pipes and lines, ensuring that the male and female connectors correspond to each other. After the system is powered on, the external hydraulic station is in standby mode, and the moving mechanism 13... Figure 1 As shown, the device is stopped at the backward limit position. At this time, the backward position sensor 115 is in contact with the bridge plate 131, and the telescopic dust cover 202 located on the side of the connecting bracket 112 near the coupling 124 is in a stretched state. The oil nozzle 204 of the annular oil storage chamber 203 inside is automatically closed by the oil seal 205 to lock the oil. The port magnetic sealing ring 201 is tightly in contact with the connecting bracket 112 and the coupling 124 to form a completely sealed dustproof space, which isolates metal scraps, dust and oil stains from the mold workshop. Subsequently, the operator triggers the docking command, and the external hydraulic station supplies oil to the hydraulic motor 123 in the forward direction, so that the hydraulic motor 123 drives the T-screw 125 to rotate through the coupling 124. Since the T-screw 125 is engaged with the threaded pair of the threaded sleeve 116, the threaded sleeve 116 is in a stationary state with the connecting bracket 112. Therefore, the rotation of the T-screw 125 will drive the drive assembly 12 and the moving mechanism 13 to move along the guide rod 126 towards the fixed base plate 101. During this process, the telescopic dust cover 202 located between the coupling 124 and the connecting bracket 112 will be compressed, causing the high-temperature resistant lubricating oil in the oil storage chamber 203 to break through the oil seal 205 under the extrusion pressure and be evenly sprayed from the oil nozzle 204 to the T-screw 125, so as to achieve on-demand oil replenishment and lubricate the T-screw 125. Excess grease is sealed inside by the telescopic dust cover 202, which will not contaminate the mold workpiece or the formed product, avoid thread jamming, and extend the service life of the drive component. At the same time, the rotation of the T-screw 125 will cause the fixing hole 216 on it to press the angle of the fixing rod 215, causing the fixing rod 215 to slide towards the elastic member 214, compressing the elastic member 214 and causing the fixing rod 215 to move out of the fixing hole 216. When the next fixing hole 216 moves to the position aligned with the fixing rod 215, the fixing rod 215 will be re-engaged by the elastic force of the elastic member 214. The above process will be repeated as the T-screw 125 rotates and moves horizontally. At this time, the lubricating oil sprayed on the T-screw 125 can also reduce the wear between the fixing rod 215 and the fixing hole 216, and extend the service life of the self-locking component. When the moving base plate 134 moves the positioning guide post 16 to the position where it is inserted into the fixed positioning guide sleeve 107 on the fixed base plate 101, if there is a misalignment between the center positions of the positioning guide post 16 and the positioning guide sleeve 107, the positioning guide post 16 will abut against the conical surface inside the positioning guide sleeve 107. As the moving base plate 134 continues to move, the conical surface of the positioning guide sleeve 107 will press against the conical surface of the positioning guide post 16, causing it to move closer to the positioning guide sleeve through the floating of the support floating rod 113 and the moving floating rod 14. The center position of 107 moves to achieve positioning guidance. The anti-scratching plate 108 made of wear-resistant ceramic on the inner wall of the positioning guide sleeve 107 can ensure that only the anti-scratching plate 108 is subjected to force during eccentric insertion, thus protecting the positioning guide sleeve 107. During the floating process, the positioning guide post 16 will drive the moving base plate 134 to deflect on the bridge plate 131, thereby causing the moving floating rod 14 to move in the floating hole 15. At the same time, the connecting bracket 112 will deflect on the bracket floating rod 113 through the component force, which will compress the disc spring 114. The movement of the floating rod 14 within the floating hole 15 compresses the internal air storage bladder 221, causing the air inside to be ejected from the inclined guide channel 224 through the exhaust one-way valve 223 and the manifold 222 towards the side of the moving base plate 134 near the bridge plate 131. This blows away the deflection area between the moving base plate 134 and the bridge plate 131, preventing debris from obstructing the floating and affecting the positioning effect. The airflow forms a swirling wind field under the guidance of the inclined guide channel 224, improving the effect of blowing away debris. When the positioning guide post 16 is inserted into the center position of the positioning guide sleeve 107, the positioning and guidance are completed. At this time, the male and female heads are aligned. When the moving plate 134 continues to move, the end faces of the male and female connectors will begin to contact and squeeze the fluororubber and PTFE double-layer composite sealing layer inside the female head: the fluororubber layer provides high elastic pre-tightening force and adaptively fills the tiny gaps on the end faces of the connectors; the PTFE layer provides excellent wear resistance, oil resistance and chemical corrosion resistance, while reducing the coefficient of friction and preventing the sealing surfaces from sticking together. When the female head and male head are docked, the forward position sensor 139 will be triggered, causing the hydraulic station to stop supplying oil to the hydraulic motor 123. At this time, the T-screw 125 stops rotating, and the fixing rod 215 will also engage with the fixing hole 216 under the elastic action of the elastic element 214, realizing the self-locking of the T-screw 125 and preventing the T-screw 125 from rotating in the opposite direction, causing the moving mechanism 13 to loosen the male and female ends. Even if the fixing rod 215 is not engaged with the fixing hole 216 at this angle, after the joint is slightly loosened, one of the fixing holes 216 will rotate to the position where it engages with the fixing rod 215. Slight loosening will not affect the sealing of the joint. After self-locking, even if the hydraulic system is completely depressurized, the joint can be prevented from loosening.

[0053] When replacement is needed in the future, simply pull the handle 212 outward to disengage the fixing rod 215 from the fixing hole 216, and then reverse the oil supply of the hydraulic station.
