Description

Technical Field

[0001] This invention relates to the field of refrigerator body foaming technology, specifically an adjustable foaming mold. Background Technology

[0002] Foaming molding is the core process in refrigerator body manufacturing. As a key piece of equipment in this process, foaming molds are essential for refrigerators. With the diversification of consumer demand in the home appliance market and the accelerated pace of product iteration, a product matrix of different specifications within the same series has become an important strategy for companies to enhance their market competitiveness. SD215L and SD235L are two core body models in a mainstream refrigerator series.

[0003] For enclosures of different lengths, it is necessary to develop dedicated integrated foaming molds. That is, to adapt to both SD215L and SD235L enclosures, it is necessary to independently complete the entire process of designing two sets of molds, procuring materials, precision machining, assembly and debugging, and trial molding verification.

[0004] While traditional solutions can guarantee the molding quality of single-specification refrigerator cabinets, the cost of mold making is exorbitant. The R&D and manufacturing cost of a single refrigerator cabinet foaming mold can typically reach several million yuan. The investment in two sets of molds will directly increase the company's initial fixed asset investment by several million yuan, significantly raising the threshold for product R&D and production. Moreover, the efficiency of production changeover is low. When the production line needs to switch between two cabinet types, the entire set of molds must be disassembled, hoisted, positioned, installed, and calibrated for precision. A single changeover typically takes 4-8 hours, during which the production line is shut down, severely reducing the production line turnover rate. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable foaming mold, which has the advantage of being able to adjust two mold sizes according to requirements, thus solving the problem of needing to develop different molds.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An adjustable foaming mold includes a main body assembly, on which a telescopic mechanism assembly is mounted, and a retraction mechanism assembly is connected to the telescopic mechanism assembly. A lifting frame assembly is also mounted on the main body assembly, and the lifting frame assembly cooperates with a sofa seat assembly. A rear baffle is mounted on one side of the main body assembly, and a front baffle is mounted on the other side. A support component is connected to the bottom of the main body assembly. The main assembly includes an end core-pulling assembly one and a movable main body. The movable main body contains a side core-pulling assembly, an end core-pulling assembly two, and a flip-plate assembly.

[0007] Preferably, the telescopic mechanism assembly includes a cylinder, a cylinder mounting bracket, and a cylinder tailstock. The cylinder mounting bracket and the cylinder tailstock are fixed to the mounting surface. The two ends of the cylinder body of the cylinder are detachably connected to the cylinder mounting bracket and the cylinder tailstock by screws. Shims are provided between the cylinder body of the cylinder and the cylinder mounting bracket and the cylinder tailstock for fine adjustment.

[0008] Preferably, the bottom of the moving plate of the telescopic mechanism assembly is provided with two wear-resistant blocks. The wear-resistant blocks are fixed to the moving plate by countersunk bolts, and the lower end face of the wear-resistant blocks slides in contact with the mounting surface. Linear guide rails are provided on both sides of the moving plate. The moving plate and the slider of the linear guide rail are fixedly connected by bolts, and the guide rail seat of the linear guide rail is fastened to the mounting surface.

[0009] Preferably, the telescopic mechanism assembly further includes a limiting block one and a limiting block two, which are located at the two ends of the stroke of the moving plate one and are fixed to the mounting surface by internal hexagon screws. The opposite sides of the limiting block one and the limiting block two are provided with buffer pads, which collide with the limiting blocks to reduce the inertial impact with the moving plate one.

[0010] Preferably, the piston rod of the first cylinder is hinged to the cylinder connecting block via a pin-connected rod, and both ends of the pin-connected rod are respectively limited by double-ear ring supports. The double-ear ring supports are welded and fixed to the cylinder connecting block, and the end of the cylinder connecting block away from the pin-connected rod is bolted to the first moving plate.

[0011] Preferably, the retraction mechanism assembly includes cylinder two, cylinder three, a fixed plate, and a cylinder mounting plate. The cylinder mounting plate is fixed to the fixed plate by mounting plate inserts, and cylinder two and cylinder three are detachably connected to the cylinder mounting plate by bolts.

[0012] Preferably, the second moving plate of the retraction mechanism assembly is slidably engaged with the first, second, third, and fourth guide posts, respectively, and the upper and lower enclosure plates are fastened to the side plate of the fixed plate by screws to achieve stable guidance of the second moving plate.

[0013] Preferably, the two ends of the connecting rod of the retraction mechanism assembly are respectively connected to connecting rod seat one and connecting rod seat two by shafts. Connecting rod seat one is fixed on moving plate two, and connecting rod seat two is fixed on side plate one. The up and down movement of moving plate two drives the connecting rod to drag connecting rod seat one and side plate one through connecting rod seat one, and moves horizontally under the guidance of guide post one.

[0014] Preferably, the inclined sliding connecting rod of the retraction mechanism assembly is connected to the moving plate connecting block and the cylinder mounting plate by screws, and the guide block in the lifting mechanism assembly is connected to the inclined sliding connecting rod by a pin.

[0015] Preferably, the piston rod of cylinder three in the lifting mechanism assembly reciprocates, and through the pushing and retracting of cylinder connector two, it drives the guide block to move back and forth. The inclined surface in the inclined slide groove pushes the pin shaft two, which drives the inclined slide connecting rod to change direction and move up and down, thereby driving the passive lifting and lowering of the retraction mechanism assembly to complete the control.

[0016] By employing the above technical solution, the present invention provides an adjustable foaming mold, which has at least the following beneficial effects: 1. This adjustable foaming mold, through the coordinated linkage structure of the telescopic mechanism assembly and the shrinkage mechanism assembly, combined with the electromagnetic signal triggered cylinder drive system and the high-precision linear guide rail guiding mechanism, achieves the function of precisely retracting the mold length to 96.5mm. It can be compatible with the foaming molding of refrigerator cabinets of two length specifications, SD215L and SD235L, without the need to develop two sets of dedicated molds. This significantly reduces the mold R&D and manufacturing costs for refrigerator manufacturers, and at the same time shortens the mold disassembly and assembly time when switching models from several hours to minutes, greatly improving production efficiency.

[0017] 2. This adjustable foaming mold, through the setting of a multi-guide post positioning motion plate guiding structure, a power transmission component of cylinder and hinged connecting rod, and a limit buffer mechanism at the end of the stroke, combined with the protective design of wear-resistant blocks and inserts, not only ensures the motion accuracy and structural stability during the mold length adjustment process, avoiding box molding defects caused by adjustment deviations, but also extends the service life of the mold through wear-resistant protection of key components, achieving dual assurance of molding quality and production stability for two specifications of products.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The following describes, with reference to the accompanying drawings, some embodiments of an adjustable foaming mold provided by the present invention.

[0022] Example 1: Combination Figures 1-5As shown, the present invention provides an adjustable foaming mold, including a main body assembly 1, a telescopic mechanism assembly 2 installed on the main body assembly 1, a shrinking mechanism assembly 3 connected to the telescopic mechanism assembly 2, a lifting frame assembly 4 installed on the main body assembly 1, the lifting frame assembly 4 cooperating with the sofa seat assembly 5, a rear baffle 7 installed on one side of the main body assembly 1, a front baffle 8 installed on the other side, and a back panel side strip 6 connected to the bottom of the main body assembly 1, realizing an integrated design of shape changing and core pulling molding functions, reducing the overall space occupied by the mold, and adapting to the installation needs of multiple scenarios; The main body assembly 1 includes an end core-pulling assembly 9 and a movable body 14. The movable body 14 is equipped with a side core-pulling assembly 10, an end core-pulling assembly 11, a flip plate assembly 12, and a pad block 13. It can flexibly move according to the core-pulling requirements of different parts of the foam, adapt to the molding of complex-shaped foam, and break through the application limitations of a single core-pulling structure.

[0023] As can be seen from the embodiments, the active body 14 serves as the mounting carrier for internal components, providing an adjustable mounting base for the end core pulling assembly 9, the flip plate assembly 12, etc., and cooperating with the mold changing mechanism to achieve rapid adaptation of foaming parts of different specifications, thereby improving the mold changing efficiency.

[0024] Example 2: Combination Figures 6-8 As shown, based on Embodiment 1, the telescopic mechanism assembly 2 includes a cylinder 213, a cylinder mounting bracket 27, and a cylinder tailstock 28. The cylinder mounting bracket 27 and the cylinder tailstock 28 are respectively fixed to the mounting surface. The two ends of the cylinder body of the cylinder 213 are detachably connected to the cylinder mounting bracket 27 and the cylinder tailstock 28 by screws. A gasket 29 is provided between the cylinder body of the cylinder 213 and the cylinder mounting bracket 27 and the cylinder tailstock 28. Compared with the single-end fixing method, the coaxiality of the cylinder during operation is greatly improved, avoiding the swaying of the piston rod during the extension and retraction process, and ensuring the accuracy of power transmission.

[0025] Specifically, the bottom of the moving plate 21 of the telescopic mechanism assembly 2 is provided with two wear-resistant blocks 23. The wear-resistant blocks 23 are fixed to the moving plate 21 by countersunk bolts, and the lower end face of the wear-resistant blocks 23 slides in contact with the mounting surface. Linear guide rails 212 are provided on both sides of the moving plate 21. The sliders of the moving plate 21 and the linear guide rails 212 are fixedly connected by bolts. The guide rail seat of the linear guide rail 212 is fastened to the mounting surface. The two symmetrically arranged wear-resistant blocks 23 at the bottom directly contact the mounting surface, replacing the sliding friction between the moving plate body and the mounting surface. By selecting wear-resistant blocks 23 made of wear-resistant material, the wear of core components can be reduced. The countersunk screw fixing method avoids the screw head protruding and interfering with the sliding, further ensuring smooth sliding.

[0026] Furthermore, the telescopic mechanism assembly 2 also includes a first limiting block 24 and a second limiting block 25. The first limiting block 24 and the second limiting block 25 are located at both ends of the stroke of the first moving plate 21 and are fixed to the mounting surface by hexagonal screws. The opposite sides of the first limiting block 24 and the second limiting block 25 are provided with buffer pads. The buffer pads selectively abut against the end face of the first moving plate 21. The first limiting block 24 and the second limiting block 25 are respectively arranged at both ends of the stroke of the first moving plate 21 to precisely limit its maximum telescopic range, avoid the moving plate from overtravel due to air pressure fluctuations or control delays, prevent collision damage with surrounding components, and ensure the consistency of the changeover dimensions.

[0027] The piston rod of cylinder 213 is hinged to cylinder connecting block 26 via pin connecting rod 214. Both ends of pin connecting rod 214 are limited by double-ear ring supports 215. Double-ear ring supports 215 are welded and fixed to cylinder connecting block 26. The end of cylinder connecting block 26 away from pin connecting rod 214 is bolted to motion plate 21. Double-ear ring supports 215 form precise limit on both ends of Y-shaped connecting rod to prevent radial movement of connecting rod during movement. Combined with the welding and fixing of double-ear ring supports 215 and cylinder connecting block 26, a double guarantee of "limiting + rigid fixing" is formed to avoid loosening of connection during power transmission.

[0028] As can be seen from the embodiments, the pin-connecting rod 214 and the cylinder connecting block 26 are hinged, which can adapt to the small angular deviation during the extension and retraction of the piston rod, avoid the jamming or stress concentration caused by rigid connection, and ensure smooth and lossless power transmission.

[0029] Example 3: Combination Figures 9-11 As shown, based on Embodiment 1, the retraction mechanism assembly 3 includes cylinder 2 328, cylinder 329, fixing plate 326, and cylinder mounting plate 317. Cylinder mounting plate 317 is fixed to fixing plate 326 by mounting plate insert 318. Cylinder 2 328 and cylinder 329 are detachably connected to cylinder mounting plate 317 by screws. Cylinder mounting plate 317 is fixed to fixing plate 326 by mounting plate insert 318. The horizontal and verticality of cylinder mounting plate 317 can be finely adjusted by the thickness of the insert to ensure the coaxiality of cylinder 2 328 and cylinder 329 and avoid power transmission offset caused by installation deviation.

[0030] The second moving plate 35 of the retraction mechanism assembly 3 is slidably engaged with the first guide post 39, the second guide post 310, the third guide post 319, and the fourth guide post 324. The upper enclosure plate 312 and the lower enclosure plate 311 are fastened to the second side plate 313 by bolts to achieve stable guidance of the second moving plate 35. The upper enclosure plate 312 and the lower enclosure plate 311 are fastened to the fixed plate 326 by screws to form a closed guide support frame, which not only provides a stable installation base for the guide post, but also distributes the force when the moving plate moves, avoids bending deformation of the guide post due to excessive force on one side, and extends the service life of the guide components.

[0031] Specifically, the two ends of the connecting rod 38 of the retraction mechanism assembly 3 are hinged to the connecting rod seat 1 36 and the connecting rod seat 2 37 respectively. The connecting rod seat 1 36 and the connecting rod seat 2 37 are fixed on the motion plate 2 35, and the connecting rod seat 2 37 is fixed on the side plate 1 31. The up and down movement of the motion plate 2 35 drives the connecting rod 38 to drag the connecting rod seat 1 36 and the side plate 1 31 through the connecting rod seat 1 36, and moves horizontally under the guidance of the guide post 1 39.

[0032] Furthermore, the inclined sliding connecting rod 320 of the retraction mechanism assembly 3 is connected to the moving plate connecting block 316 and the cylinder mounting plate 317 by screws through the second pin 322, and the guide block 321 in the lifting mechanism assembly 4 is connected to the inclined sliding connecting rod 320 through the second pin 322.

[0033] The piston rod of cylinder 329 in lifting mechanism assembly 4 reciprocates, and through the pushing and retraction of cylinder connector 325, it drives guide block 321 to move back and forth. The inclined surface in the inclined slide groove pushes pin 322, which drives inclined sliding connecting rod 320 to change direction and move up and down, thereby driving the passive lifting and lowering of retraction mechanism assembly 3 to complete the control.

[0034] Initially, the mold is adapted to the SD235L refrigerator body. When switching to the SD215L specification, the mold-making equipment first supplies retraction air to cylinder 329 of the retraction mechanism assembly 3, causing its piston rod to retract. Through the cooperation of cylinder connector 314 and cylinder connecting block 26, the moving plate 35 is driven. Under the guidance of guide post 39, guide post 310, guide post 319, and guide post 324, the moving plate 35 drives the connecting rod 38. The connecting rod 38, through connecting rod seat 36 and connecting rod seat 37, pulls side plate 31 and side plate 313 to retract autonomously in opposite directions along the X direction. The retraction mechanism 3 contracts by 32mm on each side, and the magnetic ring trigger signal of cylinder 329 is transmitted to the equipment. Subsequently, the equipment automatically switches the air source to cylinder 328 of the lifting mechanism assembly. Cylinder 328 pushes the inclined sliding connecting rod 320 in the Y-direction. Under the constraint of the guide block 321 and the inclined sliding groove of the fixed plate 326, the inclined sliding connecting rod 320 converts the horizontal thrust into the Z-direction lifting force through the cooperation of the pin 322 and the inclined surface in the inclined sliding groove, driving the retraction mechanism assembly 3 to rise stably by 36mm. At the same time, the impact plate 210 touches the proximity switch. The proximity switch triggers the air circuit switching, connecting the air source to the telescopic mechanism assembly 2. Cylinder 213 retracts its piston rod, driving the moving plate 21 via the Y-shaped pin connecting rod 214 and cylinder connecting block 26. Guided by the bottom wear-resistant block 23 and the two side linear guide rails 212, the moving plate 21 pulls the shrinking mechanism assembly 3 to slide precisely 96.5mm along the Y direction, allowing the refrigeration and freezing main bodies to close accurately, completing the conversion to the SD215L specification. After conversion, it is necessary to check whether the closing gap between the refrigeration and freezing main bodies is uniform, and confirm the shrinking amount (32mm) in the X direction, the lifting height (36mm) in the Z direction, and the moving distance in the Y direction of the shrinking mechanism assembly 3. (96.5mm) Does it meet the parameter requirements? When it is necessary to switch back to the SD235L specification or stop the machine, a reset command is issued through the box-type equipment to sequentially control the cylinder 213 of the telescopic mechanism assembly 2 to extend (driving the retraction mechanism assembly 3 back to the initial position in the Y direction), the cylinder 328 of the lifting mechanism assembly to retract (driving the retraction mechanism assembly 3 back to the initial position in the Z direction), and the cylinder 329 of the retraction mechanism assembly 3 to extend (driving the side plate 31 and the side plate 313 to reset in the X direction), so that each component is restored to the initial state adapted to the SD235L specification, waiting for the next operation.
