Description

Technical Field

[0001] This utility model relates to the field of mold blank processing technology, and in particular to a suspension device for heat treatment of mold blanks. Background Technology

[0002] The mold blank is the core basic structure in mold manufacturing. As the "skeleton" of the mold, it plays a crucial role in supporting the molding module and ensuring accuracy and stability. It is made of high-strength materials such as steel or aluminum alloy and provides installation reference and mechanical support for functional components such as cavity, ejection system, and cooling water channel.

[0003] Currently, in the process of quenching or tempering the mold blank, the mold blank is generally placed on a conveyor and sent into the heating furnace for heating. The entire bottom surface of the mold blank is in contact with the conveyor, resulting in uneven heating of the mold blank. This can easily lead to poor spheroidizing annealing or runaway quenching temperature. If the tempering is insufficient, the residual austenite content can reach 15%-20%, resulting in poor dimensional stability. On the other hand, if the quenching temperature is too high, coarse martensite may be formed, which reduces impact toughness. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a suspension device for heat treatment of mold blanks, which solves the problem that when traditional conveying devices transport mold blanks to the heating furnace, the large contact area between the bottom surface of the mold blank and the conveying device leads to uneven heat treatment.

[0005] According to an embodiment of the present invention, a suspension device for heat treatment of a mold blank includes mounting blocks, support rails, and a drive assembly. There are two mounting blocks, each mounted on a column and positioned opposite each other. Slide grooves are provided on the opposite sides of the two mounting blocks. There are two support rails, each L-shaped, positioned opposite each other. Both ends of each support rail are slidably disposed in the slide grooves. Each mounting block is also provided with an adjustment assembly for adjusting the distance between the two support rails. The drive assembly is disposed on the support rails and is used to drive the mold blank placed between the two support rails to move on the support rails.

[0006] Compared with the prior art, the present invention has the following advantages: by setting the device on the heating furnace channel, the adjusting component adjusts the distance between the two support rails to a suitable size to move the mold blank onto the support rails, and the driving component drives the mold blank into the heating furnace. Since the mold blank is suspended, there is no obstruction on its bottom surface, and there are gaps on both sides of the mold blank facing the support rails to facilitate the entry of heat. Thus, the mold blank delivered by the device into the heating furnace is heated evenly in the heating furnace, and the quality of the heat-treated mold blank meets the requirements.

[0007] Furthermore, the drive assembly includes: a crossbar, a moving groove is provided on the side wall of each support rail, two crossbars are slidably provided between the two support rails, a limiting plate is provided at both ends of each crossbar after passing through the moving groove, and a power assembly for pulling the crossbar to move is provided at both ends of each support rail.

[0008] Furthermore, the power assembly includes: a motor, with the motor provided at both ends of each support rail, and a take-up roller provided after the output end of each motor extends out of the support rail, with one end of a pull rope fixed on the take-up roller, and the other end of the pull rope connected to the end of a crossbar away from it.

[0009] Furthermore, each crossbar has a slidable collar at both ends, and the collar is fixedly connected to the corresponding pull rope.

[0010] Furthermore, the adjustment component includes: a threaded rod, with sliders fixedly provided at both ends of each support track, each slider being slidably disposed in a corresponding groove, one end of the threaded rod being rotatably connected to the slider, and the other end of the threaded rod being threadedly connected to the mounting block and having a handle after passing through the mounting block.

[0011] Furthermore, one of the crossbars is shorter than the other.

[0012] Furthermore, each limiting plate is threadedly connected to the corresponding crossbar. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 3As shown in the figure, this utility model embodiment proposes a suspension device for heat treatment of mold blanks, including mounting blocks 1, support rails 4, and a drive assembly. There are two mounting blocks 1, each positioned opposite each other via columns 2. Slide grooves 3 are provided on the opposite sides of each mounting block 1. There are two support rails 4, each L-shaped, positioned opposite each other, with both ends of each support rail 4 slidably disposed within the slide grooves 3. Each mounting block 1 is also equipped with an adjustment assembly for adjusting the distance between the two support rails 4. The drive assembly is mounted on the support rails 4 and is used to drive the mold blank placed between the two support rails 4 to move along the support rails 4. It should be noted that this device is installed in the heating furnace passage, with the columns 2 and mounting blocks 1 located outside the heating furnace. All components of this device that need to enter the heating furnace are made of high-temperature resistant materials available in the prior art. The L-shaped support rail 4 includes a vertical section and a horizontal section. Based on the size of the mold blank to be heat-treated, the worker first adjusts the distance between the two support rails 4 using an adjusting component, ensuring the distance is slightly greater than the width of the mold blank. Then, the mold blank is placed on top of the horizontal section of the two support rails 4. The drive component is activated, moving the mold blank along the length of the support rails 4. Once the mold blank reaches the middle of the heating furnace, it stops, and the heating furnace is started to heat-treat the mold blank. During the heat treatment process, because the mold blank is suspended and its bottom is unobstructed, and because the distance between the two support rails 4 is slightly greater than the width of the mold blank, there is a gap between the vertical section of the support rail 4 and the outer wall of the mold blank. This allows heat from the heating furnace to transfer from the gap to the side of the mold blank facing the support rail 4, ensuring uniform heating of the entire mold blank within the heating furnace.

[0020] like Figure 1 and Figure 3 As shown, the driving assembly further includes: a crossbar 5; a moving groove 6 is provided on the side wall of each support rail 4; two crossbars 5 are slidably arranged between the two support rails 4; each crossbar 5 has a limiting plate 7 extending through the moving groove 6 at both ends; and a power assembly for pulling the crossbar 5 is provided at both ends of each support rail 4. When the mold blank is sent into and out of the heating furnace, the power assembly is activated, and the power assembly pulls one of the crossbars 5 to move along the length of the moving groove 6, thereby allowing the crossbar 5 to push the mold blank to slide on the support rail 4. By setting a crossbar 5 on each side of the mold blank, the mold blank can be transported from one end of the support rail 4 to the other end. After the mold blank has been heat-treated, the two crossbars 5 are reset.

[0021] like Figure 1 and Figure 3As shown, the power assembly further includes: a motor 8, with each support rail 4 having a motor 8 at both ends. Each motor 8 has an output end extending from the support rail 4 and a take-up roller 9. One end of a pull rope 10 is fixed to the take-up roller 9, and the other end of the pull rope 10 is connected to the end of a crossbar 5 located away from it. When conveying the mold blank, the motor 8 starts, and the two motors 8 located at the furnace outlet wind up the pull rope 10 (at this time, the motor 8 located at the inlet releases the pull rope 10), causing the pull rope 10 to pull the crossbar 5 located away from it towards the furnace outlet, thereby driving the mold blank from the furnace inlet into the furnace. After heat treatment, the two motors 8 located at the furnace outlet wind up the pull rope 10 again, causing the crossbar 5 to push the mold blank out of the furnace. After the mold blank is removed by a robotic arm or existing clamping mechanism, the motor 8 near the inlet of the heating furnace is started. When the motor 8 winds the pull rope 10, it pulls the crossbar 5 away from it toward the inlet of the heating furnace, thereby resetting the mold blank and facilitating subsequent heat treatment operations. Preferably, the pull rope can be made of ceramic fiber or nickel-based alloy wire.

[0022] By setting two crossbars 5 on both sides of the mold blank, the motor 8 at the outlet of the heating furnace can be started to send the mold blank into the heating furnace, and the motor 8 at the inlet of the heating furnace can be started to send the mold blank out of the inlet of the heating furnace.

[0023] like Figure 1 and Figure 3 As shown, furthermore, each end of the crossbar 5 is slidably fitted with a collar 11, which is fixedly connected to the corresponding pull rope 10. The collar 11 is slidably fitted on the crossbar 5, and the limiting plate 7 can prevent the collar 11 from loosening from the crossbar 5. Since the distance between the two support rails 4 needs to be adjusted for mold blanks of different widths, the sliding of the collar 11 on the crossbar 5 allows the pull position of the pull rope 10 to remain relative to the motor 8 when the motor 8 winds up the pull rope 10, making the winding of the pull rope 10 smoother.

[0024] like Figure 1 and Figure 4As shown, the adjustment assembly further includes: a threaded rod 12, with sliders 13 fixedly mounted at both ends of each support rail 4, each slider 13 slidably disposed within a corresponding groove 3, one end of the threaded rod 12 rotatably connected to the slider 13, and the other end of the threaded rod 12 threadedly connected to the mounting block 1 and extending beyond the mounting block 1 to a handle 14. When adjusting the spacing of the support rails 4, the threaded rod 12 is rotated via the handle 14. The screwing in and out of the threaded rod 12 on the mounting block 1 pushes the slider 13 to move within the groove 3. The corresponding threaded rod 12 is adjusted as needed to change the spacing between the two support rails 4, thereby adapting to mold blanks of different sizes. It should be noted that the threaded rod 12 and the slider 13 can be connected via bearings, or an annular groove can be provided on the slider 13, allowing the end of the threaded rod 12 to rotate relative to the slider 13 without dislodging from it.

[0025] like Figure 3 As shown, furthermore, the length of one crossbar 5 is shorter than the length of the other crossbar 5. Since both ends of the support rail 4 are equipped with motors 8 winding different pull ropes 10, the different lengths of the two crossbars 5 can avoid interference between the two pull ropes 10. Correspondingly, the lengths of the take-up rollers 9 corresponding to the two sections of pull ropes 10 on the crossbars of different lengths are also different, and the end of the take-up roller 9 is flush with the end of its corresponding crossbar 5. Preferably, the motors 8 at one end of the support rail 4 and the motors 8 at the other end can be staggered in the vertical direction to reduce interference between the different pull ropes 10.

[0026] Furthermore, each limiting plate 7 is threadedly connected to the corresponding crossbar 5. The limiting plate 7 and the crossbar 5 are detachable by thread, and the crossbar 5 can be replaced by removing the limiting plate 7.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
