Description

Technical Field

[0001] This utility model belongs to the field of mold moving arm technology, specifically referring to a folding mold moving arm. Background Technology

[0002] In modern production processes such as injection molding and die casting, rapid and safe mold replacement is crucial for improving equipment utilization and production efficiency. As a core component of automated mold-changing systems, the performance of the mold-changing arm directly determines the smoothness and reliability of mold changes.

[0003] Currently, the traditional mold-moving arms commonly used in workshops are mostly one-piece or simple hinged structures, which have many inherent problems: First, the fixing method is simple and unreliable. Most of them use simple pins or bolts for locking, which is not only cumbersome to operate, but also prone to loosening under long-term equipment vibration, posing serious safety hazards. Secondly, the lack of an effective folding and storage mechanism means that the one-piece structure takes up a lot of space, and the existing simple articulated arms lack a secure lock after folding, making them prone to accidental unfolding during storage and transportation, causing inconvenience and risks. Furthermore, there is a general lack of anti-backflow mechanisms for molds. After the mold is positioned, it may slide in the opposite direction due to external forces or equipment vibrations, requiring manual intervention and affecting the continuity of the automated process. Utility Model Content

[0004] To address the aforementioned problems of unreliable fixing, lack of locking during folding, and lack of backflow prevention in traditional mold-moving arms, this invention provides a foldable mold-moving arm.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a folding mold moving arm, including a first arm group and a second arm group, wherein the first arm group includes a fixed base, a first hinge base and a first mold moving arm hinged thereto; The second arm assembly includes a fixed base, a second hinge base, and a second mold-moving arm hinged thereto; Both the first mold-moving arm and the second mold-moving arm are equipped with plug-in fixing components; The first and second mold-moving arms are also provided with auxiliary fixing components.

[0006] Furthermore, the plug-in fixing assembly includes a positioning screw hole with internal threads opened on the first hinge seat and the second hinge seat, a fixing screw hole opened on the first hinge seat and the second hinge seat and perpendicular to the positioning screw hole, and a fixing screw with anti-loosening washer threaded into the fixing screw hole.

[0007] Furthermore, the auxiliary fixing assembly includes a socket fixed to the second mold moving arm, a threaded rod with screws inserted into the socket, and an auxiliary block fixed to the side of the second hinge seat and having a through hole.

[0008] Furthermore, the first mold-moving arm and the second mold-moving arm have support grooves at the top center, and the bottom support parts of the two are in the shape of a broken line. The free ends of the first and second mold-moving arms are symmetrically provided with through slots, and a blocking component is provided in the through slot; The free end of the first mold-moving arm is a through structure, and the free end of the second mold-moving arm is connected to a baffle.

[0009] Furthermore, the socket is fixed to the baffle.

[0010] Furthermore, multiple sets of evenly distributed rollers are rotatably installed in the support groove, and an auxiliary wheel with the same axis as the rollers is rotatably provided on the top of the second hinge seat. The total number of auxiliary wheels of the second hinge seat and rollers of the second mold-moving arm is equal to the number of rollers of the first mold-moving arm.

[0011] Furthermore, the blocking assembly includes a zigzag-shaped blocking block rotatably mounted in the through slot, a spring, and a limiting block fixed to the first mold moving arm and the second mold moving arm; One end of the spring is fixed to the inner wall of the block, and the other end is fixed to the corresponding limiting block.

[0012] Furthermore, the mounting base is provided with multiple sets of mounting holes evenly distributed on it.

[0013] Furthermore, the length of the second hinge seat is greater than that of the first hinge seat.

[0014] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure: 1. By using the plug-in fixing components, the self-locking characteristics of the threaded pair and the anti-loosening washer provide a reliable and vibration-resistant rigid lock for the mold moving arm in both the unfolded (working) and folded (storage) states. The operation is simple, the positioning is accurate, and the stability and safety of the mold moving operation are effectively guaranteed.

[0015] 2. By setting up auxiliary fixing components and adopting the principle of pin-type mechanical locking, a rigid connection between the two arm groups can be quickly achieved through the threaded rod in the folded state, preventing accidental unfolding, simplifying the fixing operation, greatly facilitating the storage and transportation of the equipment, and improving space utilization.

[0016] 3. By setting up the blocking components and utilizing the cooperation of springs, blocking blocks, and limit blocks, an automatic anti-return function for one-way mold passage is achieved. This mechanism can automatically reset after the mold passes through and effectively prevent mold backflow or accidental slippage using the mechanical self-locking principle, thereby improving the automation level and safety of the mold moving process.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, the present invention provides a folding mold-moving arm, comprising a first arm assembly 1 and a second arm assembly 2. The first arm assembly 1 includes a fixed base 11, a first hinge base 12, and a first mold-moving arm 13 hinged thereto. The second arm assembly 2 includes a fixed base 11, a second hinge base 21, and a second mold-moving arm 22 hinged thereto. The fixed base 11 is evenly provided with multiple sets of mounting holes for quick positioning and installation on the machine tool table via bolts. The length of the second hinge base 21 is greater than that of the first hinge base 12, and this length difference provides clearance for folding the first arm assembly 1. By setting two independent arm assemblies and using a hinged connection, the mold-moving arm has a folding function, which facilitates reducing space occupation when not in use and unfolding to support and transfer molds when in use. Both the first mold-moving arm 13 and the second mold-moving arm 22 are provided with plug-in fixing components 3, which are used to lock the corresponding mold-moving arm in the unfolded or folded position; the first mold-moving arm 13 and the second mold-moving arm 22 are also provided with auxiliary fixing components 4, which are used to fix the two arms in the folded state.

[0023] like Figure 1-5 As shown, the plug-in fixing assembly 3 includes a positioning screw hole 31 with internal threads on the first hinge seat 12 and the second hinge seat 21, a fixing screw hole 32 on the first hinge seat 12 and the second hinge seat 21 and perpendicular to the positioning screw hole 31, and a fixing screw 34 with an anti-loosening washer 33 threaded into the fixing screw hole 32. The self-locking characteristic of the threaded pair achieves reliable connection and fixing. Screwing the fixing screw 34 into the fixing screw hole 32 locks the mold moving arm in the working position; screwing it into the positioning screw hole 31 locks it in the folded position. The anti-loosening washer 33 prevents the fixing screw 34 from loosening during equipment vibration, enhancing the reliability of the locking mechanism.

[0024] like Figure 1-4As shown, the auxiliary fixing assembly 4 includes a socket 41 fixed to the second mold-moving arm 22, a threaded rod 42 with screws 44 inserted into the socket 41, and an auxiliary block 43 with through holes fixed to the side of the second hinge seat 21, employing a pin-type mechanical locking principle. When both arms are folded, the threaded rod 42 passes through the through holes on both the socket 41 and the auxiliary block 43, and is fixed with screws 44, thereby rigidly connecting the two arm assemblies together, preventing relative movement and simplifying the fixing operation.

[0025] like Figure 1-4 As shown, the first mold-moving arm 13 and the second mold-moving arm 22 have support grooves 5 at their top center, and the bottom support parts of both are in a zigzag shape, which enhances the structural rigidity and bending strength of the arm body; the support grooves 5 provide a foundation and space for installing rollers 51; multiple sets of evenly distributed rollers 51 are rotatably installed in the support grooves 5, and the top of the second hinge seat 21 is rotatably provided with auxiliary wheels 52 on the same axis as the rollers 51; the total number of auxiliary wheels 52 of the second hinge seat 21 and the rollers 51 of the second mold-moving arm 22 is equal to the number of rollers 51 of the first mold-moving arm 13; this ensures that the number of support points (i.e., the number of rollers 51) of the folding mold-moving arm remains consistent when supporting the mold movement, avoiding mold jamming or overturning due to insufficient support, and ensuring a smooth transition in the transmission process; The free ends of the first mold-moving arm 13 and the second mold-moving arm 22 are symmetrically provided with through slots 6, and a blocking component 8 is provided in the through slots 6; wherein the free end of the first mold-moving arm 13 is a through structure, and the free end of the second mold-moving arm 22 is connected to a baffle 7; the socket 41 is fixed to the baffle 7; the blocking component 8 includes a zigzag-shaped blocking block 81 rotatably installed in the through slot 6, a spring 82, and a limiting block 83 fixed to the first mold-moving arm 13 and the second mold-moving arm 22; one end of the spring 82 is fixed to the inner wall of the blocking block 81, and the other end is fixed to the corresponding limiting block 83; the limiting block 83 provides a mechanical limit to the rotation of the rotating blocking block 81, preventing it from losing its blocking function on the mold on the roller 51 due to excessive rotation, and avoiding the mold from accidentally sliding out. When the mold slides in along the roller 51 group, its bottom pushes the blocking block 81 to rotate around the axis and flip down to make way; after the mold has completely passed, the spring 82 immediately drives the blocking block 81 to spring back to the initial upright state. If the mold moves in the opposite direction, its sidewall will hit the inclined limiting surface of the block 81. Since the block 81 is constrained by the limiting block 83, it cannot rotate in that direction, thus achieving mechanical self-locking and effectively preventing the mold from flowing back.

[0026] In practical use, the first step is to install and prepare the equipment. The operator selects the appropriate mounting holes on the mounting base 11 according to the distribution of threaded holes on the machine tool table, and uses bolts to securely install the entire mold-moving arm at the designated position. Then, according to operational needs, the mold-moving arm is switched between extended and folded states. If it needs to be extended to the working state, the first arm assembly 1 and the second arm assembly 2 can be manually extended until they are fully straight. Then, the fixing screws 34 in the insertion fixing assembly 3 are tightened so that they are screwed into the corresponding fixing screw holes 32. The self-locking characteristic of the threads rigidly locks the two mold-moving arms in the working position, and the anti-loosening washers 33 on them effectively prevent the fixing screws 34 from loosening due to equipment vibration.

[0027] Next, the mold is transferred and positioned. The mold is hoisted or pushed onto the extended mold-moving arm, with its bottom contacting the rollers 51 in the support groove 5. Since the sum of the number of auxiliary wheels 52 on the second hinge seat 21 and the number of rollers 51 on the second mold-moving arm 22 is equal to the number of rollers 51 on the first mold-moving arm 13, the mold receives continuous and stable support when sliding on the roller set 51, without the risk of jamming or overturning. When the mold slides into the end of the block 81 of the mold-moving arm, its bottom will press down on the block 81 in the through groove 6, causing it to temporarily tilt downwards to allow passage. After the mold has completely passed, the block 81 will immediately and automatically spring back to an upright position under the action of the spring 82. If the mold moves in the opposite direction, its side wall will hit the inclined limiting surface of the block 81. Since the block 81 is constrained by the limiting block 83, it cannot rotate in the opposite direction, thus achieving mechanical self-locking, effectively preventing the mold from flowing back, and ensuring safety after positioning.

[0028] Finally, the work is completed and the components are stored. The operator first loosens the fixing screw 34, removing it from the fixing screw hole 32, and then screws it into the positioning screw hole 31 to lock the mold-moving arm in the folded position. Then, the first arm assembly 1 and the second arm assembly 2 are folded towards the center. After folding, the threaded rod 42 of the auxiliary fixing component 4 is removed. One end is inserted into the socket 41 fixed to the baffle 7, and the other end is inserted into the through hole of the auxiliary block 43 on the side of the second hinge seat 21. Then, the screw 44 is screwed into the end of the threaded rod 42, forming a rigid connection to prevent the two arm assemblies from accidentally unfolding during storage or transport, greatly saving space and ensuring operational safety.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
