[0002] like Figure 1 As shown, there is a workpiece whose overall shape is a flat thin-walled part 8. After processing, this thin-walled part 8 has high requirements for product flatness, which usually needs to be maintained within the range of 0.3mm.

[0003] For the above-mentioned workpieces, the existing production method mainly adopts die-casting. However, in the actual production process, it is found that due to the thinness of the overall product, the product is prone to deformation during the die-casting process, resulting in the flatness of the produced product not meeting the standard.

[0004] Therefore, there is an urgent need for a device that can adjust the flatness of the above-mentioned products to meet the standards. Utility Model Content

During this closing process, the temperature control module controls the temperature in the upper shaping cavity and the lower shaping cavity to be maintained within a specified temperature range, thereby heating the thin-walled part. After the thin-walled part is heated for a period of time, the problem of deformation of the thin-walled part can be solved through this heating and closing process, thereby ensuring the flatness of the thin-walled part and avoiding the problem of stress rebound in the thin-walled part during the shaping process.

[0044] Reference Figure 3 and Figure 4 When in use, first install the first insulation base plate 51 on the upper mold mounting plate 12, then install the upper mold core 13 on the first insulation base plate 51, and finally install the four first insulation side plates 52 on the side plates around the upper mold core 13, so that the first insulation base plate 51 and the four first insulation side plates 52 can enclose the upper mold core 13 in the upper insulation cavity, so that during the heating process of the upper mold core 13, the heat of the upper mold core 13 is blocked from causing thermal expansion of other parts, and the heat loss of the upper mold core 13 is also reduced, ensuring that the temperature in the upper insulation cavity is stably maintained at the specified degree, thereby ensuring the effect of subsequent adjustment of the thin-walled part 8.

[0045] Reference Figure 2 and Figure 3 The lower mold 2 is divided into a lower mold core 24, a lower mold mounting plate 23, a lower mold bottom plate 21 and a mold foot 22 from top to bottom, wherein the mold foot 22 is used to support the lower mold bottom plate 21, and the mold foot 22 is fixedly connected to the lower mold bottom plate 21 by bolts. The lower mold mounting plate 23 is placed on the lower mold bottom plate 21, and a second heat blocking structure 6 is arranged between the lower mold mounting plate 23 and the lower mold core 24.

A mounting hole 611 is provided on the bottom wall of the second heat-insulating bottom plate 61, and an embedding groove 211 is provided on the upper end surface of the lower mold bottom plate 21. When in use, the top end of the second connecting stud 25 is first passed through the lower mold mounting plate 23 and the mounting hole 611 in turn and then threadedly connected to the lower mold core 24, thereby completing the assembly of the lower mold core 24, the lower mold mounting plate 23 and the second heat-insulating bottom plate 61. After that, the lower mold mounting plate 23 is placed as a whole on the lower mold bottom plate 21, and the bottom end of the second connecting stud 25 is embedded in the embedding groove 211, thereby realizing the positioning of the lower mold mounting plate 23, thereby realizing the assembly of the lower mold 2.

[0047] Reference Figure 3 and Figure 5 The second insulation side panels 62 are fixed to the four side walls of the lower mold core 24 by bolts. In this embodiment, the lower mold core 24 also has a rectangular block structure. Therefore, four second insulation side panels 62 are provided, and the four second insulation side panels 62 are enclosed to form a rectangular frame structure, which can be combined with the second insulation bottom plate 61 to form a lower insulation cavity. When the lower mold core 24 and the second insulation side panels 62 are installed on the second insulation bottom plate 61, the second insulation side panels 62 and the second insulation bottom plate 61 can be used to achieve the purpose of insulating the lower insulation cavity.

[0048] Reference Figure 3 and Figure 5 A second set of temperature control modules 4 is provided in the lower mold core 24. When in use, the temperature control module 4 controls the temperature rise of the lower mold core 24. During the temperature rise process, the cooperation of the second thermal insulation side plate 62 and the second thermal insulation bottom plate 61 can achieve the effect of blocking the thermal expansion of the lower mold core 24 on other components caused by the temperature rise, and at the same time reduce the heat loss of the lower mold core 24, ensuring that the temperature in the lower insulation cavity is stably maintained at the specified degree.

[0049] Reference Figure 4 In this embodiment, a group of temperature control modules 4 installed in the upper mold core 13 and another group of temperature control modules 4 installed in the lower mold core 24 are set up in the same manner and layout. Therefore, the connection method of the temperature control module 4 in the upper mold core 13 is described. The temperature control module 4 is composed of several groups of heating tubes 41. Several groups of heating tubes 41 are distributed at intervals on the upper mold core 13. In this embodiment, the heating tubes 41 are set into two groups. The two groups of heating tubes 41 are symmetrically arranged at both ends of the upper mold core 13. Each group includes 6 heating tubes 41. One end of the heating tube 41 extends into the upper mold core 13 and is fixed to the upper mold core 13 by bolts. The other end of the heating tube 41 is connected to the external temperature controller through a wire.

[0050] Reference Figure 4 When in use, the staff controls the external temperature controller to drive the heating tube 41 to start, so that the upper mold core 13 is heated as a whole through the joint action of multiple heating tubes 41, thereby ensuring that the temperature of the upper mold core 13 is always maintained at the specified degree. In this application, the temperature of the upper mold core 13 needs to be maintained at about 220 degrees Celsius.

[0051] Reference Figure 2 and Figure 3A guide structure 3 is also provided between the upper mold 1 and the lower mold 2.

The bottom end of the second guide column 31 is fixed on the lower mold base plate 21, and the top end of the second guide column 31 is provided with a guide slope. The top end of the second guide sleeve 32 is fixed on the upper mold base plate 11, and the bottom end of the second guide sleeve 32 extends to the bottom of the upper mold base plate 11 and forms a plug-in fit with the second guide column 31. When in use, first move the upper mold 1 to align the second guide sleeve 32 with the second guide column 31, and then move the upper mold 1 downward. Under the action of the second guide column 31, the upper mold 1 gradually approaches the lower mold 2, while also ensuring the rapid alignment of the upper shaping cavity and the lower shaping cavity.

[0052] Reference Figure 2 and Figure 3 A positioning structure 7 is provided between the upper mold base plate 11 and the lower mold base plate 21. The positioning structure 7 is used to position the upper mold 1 and the lower mold 2 after completing the mold closing state. The positioning structure 7 is composed of an upper mold limit block 71 bolted to the upper mold base plate 11 and a lower mold limit block 72 bolted to the lower mold base plate 21. A first avoidance hole 711 is opened through the upper mold limit block 71, and a second avoidance hole 721 is opened through the lower mold limit block 72. When the upper mold limit block 71 is installed on the upper mold base plate 11 and the lower mold limit block 72 is installed on the lower mold base plate 21, the bottom end of the second guide sleeve 32 is inserted into the first avoidance hole 711, and the top end of the second guide column 31 passes through the second avoidance hole 721 and extends into the first avoidance hole 711, and is plugged into and engaged with the second guide sleeve 32.

[0053] The implementation principle of the embodiment of the present application is as follows: when in use, first assemble the lower mold 2 and the upper mold 1, and fix the lower mold 2 flatly in the specified position, fix the upper mold base 11 in the upper mold 1 to the mounting plate of the hydraulic press, and then place the thin-walled part 8 in the lower shaping cavity, and then control the heating of the lower mold core 24 and the upper mold core 13 through the temperature control module 4, so that the temperature of the lower mold core 24 and the upper mold core 13 is maintained at about 220 degrees Celsius. At this time, it is necessary to heat and shape the thin-walled part 8 at a temperature of 220 degrees Celsius for about 1 minute. During this heating process, the thin-walled part 8 will gradually heat up, and then the upper mold 1 can be driven downward by the hydraulic press; after moving downward During the molding process, the second guide column 31 is first inserted into the second guide sleeve 32. When the upper mold core 13 and the lower mold core 24 gradually abut against each other, the first guide column 15 is inserted into the second guide column 31, and the return spring 17 is gradually compressed until the upper mold limit block 71 abuts against the lower mold limit block 72. The upper mold 1 and the lower mold 2 are then closed. At the same time, under the influence of the elastic force of the return spring 17, the upper mold core 13 and the lower mold core 24 are pressed against each other, thereby achieving the purpose of adjusting the flatness of the thin-walled part 8 to the standard overall flatness through the above-mentioned heating and closing process. In this way, the adjusted thin-walled part 8 is ensured to have high flatness, and no emergency rebound will occur during the adjustment process, which is more conducive to actual processing and use.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
