Description

Technical Field

[0001] This utility model relates to the field of hydraulic mold technology, and in particular to a hydraulic mold device for cold storage panels. Background Technology

[0002] In the manufacturing process of cold storage panels, hydraulic mold devices are key equipment to ensure product forming quality and production efficiency. By applying pressure to the sheet material through the hydraulic mold device, and in conjunction with the specific structure of the mold, precise forming of cold storage panels can be achieved, including complex shape shaping, hole processing, and other processes. Its performance directly affects the dimensional accuracy, structural strength, and surface quality of the cold storage panels.

[0003] However, existing hydraulic molds lack effective support structures for the portion of the sheet metal extending beyond the mold edge during the stamping process of cold storage panels. This leads to localized deformation or wobbling of the sheet metal under stress. Due to the unpredictable nature of the sheet metal deformation, the relative position between the mold and the sheet metal shifts, causing the mold punch to fail to act vertically and stably on the sheet metal during stamping. This results in tilted punched holes and deviations between the formed cold storage panel shape and the design dimensions, affecting subsequent assembly and use. Therefore, a hydraulic mold device for cold storage panels needs to be designed.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a hydraulic mold device for cold storage panels to solve the problem that existing hydraulic molds do not provide sufficient support for the panels that extend beyond the mold edge, causing the panels to deform and shake, and the relative position of the mold and the panels to shift, which affects the subsequent assembly of the cold storage panels.

[0006] This utility model embodiment adopts the following technical solution: a hydraulic mold device for cold storage panels.

[0011] A first slide rail is slidably installed between the two sets of angle seats arranged horizontally. A sliding block adapted to slide along the first slide rail is installed on the bottom surface of the angle seat. One end of the first slide rail is installed on an extension rod, and the other end of the first slide rail is adapted to be fixed to the workbench by a second bolt.

[0012] Furthermore, the two sets of sliding blocks arranged laterally are connected by connecting rods. The two sets of sliding blocks and one set of connecting rods are defined as sliding parts. The two sets of sliding parts are fixed to the position on the first slide rail by fasteners.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1 to 6 As shown, this utility model embodiment provides a hydraulic mold device for cold storage panels, including a workbench 1, a hydraulic component 2, a support component 3, a pressing component 4, and an extension component 5;

[0028] The hydraulic assembly 2 includes a lower mold 21 mounted on a workbench 1. The lower mold 21 is fixedly mounted with a top plate 23 via four sets of guide rods 22, and an upper mold 25 is slidably mounted on the four sets of guide rods 22. At the same time, a hydraulic cylinder 24 is fixedly mounted on the top plate 23, and the output end of the hydraulic cylinder 24 passes through the top plate 23 and is connected to the upper mold 25.

[0029] During the operation of the hydraulic component 2, the cold storage panel is placed on the lower mold 21. Four sets of guide rods 22 ensure the relative positional accuracy and motion stability between the upper mold 25 and the lower mold 21. The hydraulic cylinder 24 is activated, generating thrust at its output end, pushing the upper mold 25 on the top plate 23 to slide downwards along the guide rods 22. During this process, the upper mold 25 and the lower mold 21 gradually approach each other, applying pressure to the cold storage panel placed on the lower mold 21 to complete the stamping operation. After stamping, the output end of the hydraulic cylinder 24 retracts, causing the upper mold 25 to slide upwards along the guide rods 22, separating from the lower mold 21, facilitating the removal of the formed cold storage panel. The entire process utilizes hydraulic transmission to achieve efficient and precise stamping of the cold storage panel.

[0030] The support assembly 3 includes four sets of corner brackets 31 fixedly installed on the workbench 1 and located on one side of the lower mold 21. The four sets of corner brackets 31 are symmetrically arranged, and a guide rail 32 is connected between two sets of horizontally arranged corner brackets 31 (see reference). Figure 2 );

[0031] Two sets of movable units are slidably connected between the two sets of guide rails 32. The two sets of movable units are symmetrically arranged along the straight line of the guide rails 32. Each movable unit includes two sets of covers 38 that are slidably sleeved on the two sets of guide rails 32. Guide wheels 381 adapted to slide along the guide rails 32 are rotatably installed on the upper and lower surfaces of the inner wall of the cover 38. The cover 38 slides along the straight line of the guide rails 32 through the guide wheels 381. A support plate 36 is fixedly connected between the two sets of covers 38. The support plate 36 is used to support the part of the cold storage plate that extends out of the mold.

[0032] The two activity units are arranged here according to Figure 3 The perspective, from left to right, is defined as the first active unit and the second active unit, and the cover 38 of the second active unit is defined as the cover 39.

[0033] Meanwhile, a drive unit is installed between the two sets of guide rails 32. The drive unit is adapted to drive the first movable unit and the second movable unit to move closer or further away from each other. The drive unit includes a fixed cover 33 installed on the two sets of guide rails 32. Sliding wheels 34 adapted to slide on the guide rails 32 are fixedly installed at the upper and lower ends of the inner wall of the fixed cover 33. The fixed cover 33 is fixed to the guide rails 32 by fasteners, and gears 35 are mounted on the fixed cover 33 by bearings.

[0034] Meanwhile, rack 1 382 and rack 2 383 are provided on one side of the guide rail 32, and rack 1 382 and rack 2 383 are both meshed with gear 35. Rack 1 382 is fixedly connected to cover 1 38, and rack 2 383 is fixedly connected to cover 2 39. Gear 35 has a central shaft, and the central shafts of gear 35 on the two sets of fixed covers 33 are connected by connecting rod 37. The central shaft passes through the guide rail 32 and the movable cover in sequence, and a turntable 384 is mounted on the side bearing of cover 1 38. The turntable 384 is connected to one end of the central shaft.

[0035] Furthermore, a support plate 310 is fixedly connected between the two sets of fixed covers 33. The support plate 310 is suitable for supporting the part of the cold storage panel that extends out of the mold, so as to provide balanced support for the part of the cold storage panel that extends out of the mold.

[0036] The support component 3 achieves synchronous opposite / backward movement of the moving units through a gear and rack transmission system (35 gears), forming multi-point balanced support in conjunction with the fixed and moving support structures, effectively improving the stamping stability of the cold storage panel. Its working principle is as follows:

[0037] When support is needed for the portion of the cold storage panel extending from the mold, the drive unit begins operation. The operator rotates the turntable 384, causing the central shaft connected to it to rotate, which in turn causes the gears 35 on the two sets of fixed covers 33 to rotate synchronously via the connecting rod 37. Since the gears 35 mesh with racks 382 and 383 fixed on cover 38 and cover 39 respectively, when the gears 35 rotate, the two sets of racks generate opposite movements due to the meshing transmission, driving the first and second movable units to move closer or further apart along the guide rail 32.

[0038] During movement, the guide wheels 381 of cover 1 38 and the sliding wheels 34 on the inner wall of cover 2 39 roll along the guide rail 32, reducing friction and ensuring smooth movement. When the movable unit is adjusted to the appropriate position, the combined action of support plate 1 36 and support plate 2 310 fixed between the two sets of fixed covers 33 forms a multi-point balanced support structure, providing stable support for the part of the cold storage panel that protrudes from the mold, effectively solving the problem of deformation and shaking of the panel due to lack of support during stamping, and ensuring the stamping accuracy and quality of the cold storage panel.

[0039] In this application, to address the problem that the turntable 384 lacks a locking function after driving the first and second cover bodies 39 to displacement, which easily leads to secondary displacement of the movable cover, the turntable 384 is replaced with a drive unit. This drive unit is fixedly installed on the side of one of the movable covers and coaxially connected to the central shaft to achieve precise positioning of the movable cover, prevent displacement of the movable cover along the guide rail 32 due to external interference or vibration, ensure the support stability of the support assembly 3 for the extended part of the cold storage panel, and improve the stamping accuracy;

[0040] like Figures 3-5 As shown, specifically, the pressing assembly 4 is installed on the movable cover and multiple sets are provided. The pressing assembly 4 includes a fixed seat 41 fixed on the movable cover, and a cylinder 42 is installed on the fixed seat 41 near one side end. A base 43 is fixedly installed on the fixed seat 41. A connecting rod 44 is movably connected between the base 43 and the telescopic end of the cylinder 42. A rotating rod 45 is movably connected to the base 43. A driving rod 47 is movably connected between the telescopic end of the cylinder 42 and the rotating rod 45. A pressing plate 46 is fixedly installed at one end of the rotating rod 45. An anti-slip pad is provided at the contact position between the pressing plate 46 and the cold storage plate. The anti-slip pad is made of silicone.

[0041] When it is necessary to press and fix the cold storage panel, cylinder 42 starts to work. The telescopic end of cylinder 42 extends, pushing connecting rod 44 to rotate around the connection point on base 43. At the same time, driving rod 47 also moves with the telescopic end of cylinder 42. Since driving rod 47 is movably connected to rotating rod 45, rotating rod 45 will rotate at the connection point on base 43. As rotating rod 45 rotates, the pressure plate 46 fixed at one end will move downward until the silicone anti-slip pad on pressure plate 46 contacts the surface of cold storage panel and applies pressure, pressing the cold storage panel tightly.

[0042] The silicone anti-slip pad increases friction with the surface of the cold storage panel, preventing it from sliding during stamping and other processing, thus ensuring processing accuracy. After processing is complete, the telescopic end of cylinder 42 retracts, causing connecting rod 44 and driving rod 47 to move in the opposite direction. This causes rotating rod 45 to lift the pressing plate 46 upwards, releasing the cold storage panel for subsequent operations. Simultaneously, it prevents positional shifts or wobbling due to external forces during stamping and other processing, ensuring the cold storage panel remains stable during processing and guaranteeing processing accuracy.

[0043] It should be noted that the clamping component 4 adopts the pneumatic switching clamp structure in the existing technology, and its working principle will not be described in detail here.

[0044] like Figure 3 and Figure 6 As shown, specifically, the extension assembly 5 includes an extension rod 54 slidably mounted at one end of the worktable 1, and second slide rails 53 are fixedly mounted on both sides of the worktable 1. At the same time, a slide rod 55 adapted to the second slide rail 53 is fixedly mounted on the side of the extension rod 54 near the second slide rail 53. The slide rod 55 is adapted to be fixed on the second slide rail 53 by a first bolt.

[0045] Meanwhile, a first slide rail 51 is slidably installed between two sets of horizontally arranged corner seats 31. A sliding block 52 adapted to slide on the bottom surface of the corner seat 31 is fixedly installed. One end of the first slide rail 51 is fixedly installed on the extension rod 54, and the other end of the first slide rail 51 is suitable for being fixed to the workbench 1 by a second bolt. When supporting a cold storage panel that exceeds the length of the workbench 1, the second bolt and the first bolt are loosened, and the extension rod 54 is pulled to slide along the straight direction of the second slide rail 53 until it moves to the appropriate position. Then, the second bolt and the first bolt are screwed in to fix the extension rod 54 and one end of the first slide rail 51 respectively.

[0046] It should be noted that the two sets of sliding blocks 52 arranged horizontally are connected by connecting rods (see reference). Figure 3Here, two sets of sliding blocks 52 and a set of connecting rods are defined as sliding parts. After the extension rod 54 has been moved as a whole, the position of the two sets of sliding parts on the first slide rail 51 can be adjusted by adjusting the position of the two sets of sliding parts and fixed by fasteners to adjust the overall position of the support component 3. In this application, since the core function of the support component 3 in this device is to provide basic support for the part of the cold storage panel that extends beyond the mold, its displacement accuracy only needs to meet the approximate positioning requirements of engineering applications. Therefore, in actual operation, visual positioning can meet the usage requirements, and there is no need to achieve precise and balanced support for the extended part of the cold storage panel.

[0047] The extension component 5 works by using dual-rail sliding and segmented adjustment to flexibly expand the support range. When supporting a cold storage panel that exceeds the length of the workbench 1, the operator first loosens the first bolt fixing the slide rod 55 and the second bolt fixing the first slide rail 51, allowing the extension rod 54 to slide along the second slide rail 53, thus extending the first slide rail 51 synchronously. After adjusting to the appropriate position, the bolts are tightened to lock the extension rod 54 and the first slide rail 51. Subsequently, by loosening the fasteners of the sliding part (two sets of sliding blocks 52 and connecting rod), it slides along the first slide rail 51, thereby adjusting the overall position of the support component 3. Since the support component 3 mainly undertakes the basic support function, visual positioning is sufficient to meet the approximate positioning requirements in actual operation, without the need for precise calibration. This allows it to be adapted to support cold storage panels within a certain length range, effectively improving the equipment's versatility.

[0048] Working principle: During overall operation, the cold storage panel is first placed on the lower mold 21 of the hydraulic component 2. The hydraulic cylinder 24 is activated, and its output end pushes the upper mold 25 down along the guide rod 22 to complete the stamping process. During this process, if the cold storage panel exceeds the edge of the mold, the drive part of the support component 3 drives the gear 35 to rotate, and the movable unit moves through the rack and pinion transmission. This, together with the first support plate 36 and the second support plate 310, forms multi-point support to prevent local deformation or shaking of the panel. At the same time, the cylinder 42 of the pressing component 4 extends, and the pneumatic switching clamp structure presses down the pressing plate 46. The silicone anti-slip pad increases the friction and prevents the panel from shifting. If the cold storage panel exceeds the length of the workbench 1, the bolts of the extension component 5 can be loosened, and the extension rod 54 and the sliding part can be slid to adjust the position of the support component 3 to accommodate panels of different lengths.

[0049] The multi-point balanced support of the support component 3 effectively solves the problem of deformation and shaking of the plate due to lack of support, ensures the relative position stability of the mold and the plate, and enables the punch to act vertically and stably on the plate, reducing hole tilting and shape deviation; the clamping component 4 further enhances the plate fixing effect and improves the forming accuracy; the extension component 5 realizes flexible support for plates of different lengths and expands the applicability of the equipment.
