Description

Technical Field

[0001] The utility model relates to the technical field of material forming, in particular to a thick plate thermoforming mould. Background Art

[0002] With the rapid development of the manufacturing industry, the requirements for material forming technologies are becoming increasingly stringent. Thick plate materials, due to their high strength and rigidity, are widely used in the automotive, aerospace, and construction industries. However, forming thick plate materials is challenging, and traditional cold stamping processes often cannot meet these requirements. Therefore, hot forming technology has emerged. This technology heats the material to a certain temperature, reducing its yield strength and tensile strength, thereby improving its plasticity and formability.

[0003] In the traditional thermoforming process of thick plates, the heated thick plates are first placed in the mold, and then the thick plates are stamped into shape by stamping equipment. After stamping, the thick plates are taken out after cooling and necessary trimming and cutting are performed to obtain the final required part shape and size.

[0004] However, since the thick plate is stamped into one piece, and the thick plate fits tightly with the molding cavity in the mold, and the complexity of the mold structure increases the difficulty of disassembly, the molded thick plate is easily damaged during the removal process, affecting the molding quality. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a thick plate thermoforming die. After stamping, the thick plate can be removed by simply removing the forming frame and then trimming the thick plate. This improves the efficiency of thick plate disassembly and reduces damage to the formed thick plate, ensuring the integrity and aesthetics of the thick plate.

[0006] To achieve the above-mentioned purpose, according to the embodiment of the first aspect of the present utility model, a thick plate thermoforming mold is proposed, including a lower mold, a forming frame and an upper mold, a boss is provided on the top of the lower mold, a forming groove is provided on the boss, and a first bevel is provided on the outer peripheral wall of the boss; a panel is provided in the forming frame, a second bevel is provided around the bottom of the panel, and the second bevel is interlocked with the first bevel; a positioning block is provided around the bottom of the forming frame, a positioning groove is provided around the top of the lower mold, the positioning groove is located on the outside of the boss, and the size of the positioning block is adapted to the positioning groove; a stamping plate is provided at the bottom of the upper mold, and the size of the stamping plate is adapted to the internal size of the forming frame; the forming frame is installed on the lower mold, wherein the top of the panel and the top of the boss are at the same height.

[0007] As a further solution of the present invention: a cooling mechanism is provided inside the lower mold, and the cooling mechanism includes a water inlet pipe, a water outlet pipe and a cooling cavity. The water inlet pipe is provided on the side wall on one side of the lower mold, and the water outlet pipe is provided on the side wall on the other side of the lower mold. The cooling cavity is provided inside the lower mold and has an S-shaped design, and the two ends of the cooling cavity are respectively connected to the water inlet pipe and the water outlet pipe.

[0008] As a further solution of the present invention: ear plates are provided on the side walls on both sides of the forming frame, and grabbing grooves are provided on the bottom of the ear plates.

[0009] As a further solution of the present invention: the side wall of the forming frame is provided with a temperature detection hole, and the temperature detection hole is arranged above the enclosure.

[0010] As a further solution of the present invention: a mounting seat is provided at the center of the top of the upper mold.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model ensures the precise alignment between the forming frame and the lower mold through the mutual engagement of the first bevel and the second bevel, and the cooperation of the positioning block and the positioning groove, thereby improving the forming accuracy. At the same time, it also enhances the stability of the mold during the stamping process, and prevents the mold from being deformed or damaged. After the stamping is completed, since the stamping plate is adapted to the internal dimensions of the forming frame, the height of the enclosure is consistent with that of the boss, so that waste materials of the edge of the thick plate are accumulated around the enclosure. When taking out the formed thick plate, it is only necessary to take out the forming frame to bring out the thick plate, and then the thick plate can be trimmed, thereby improving the efficiency of thick plate disassembly and reducing damage to the formed thick plate, thereby ensuring the integrity and aesthetics of the thick plate.

[0013] 2. This utility model introduces cooling water or other cooling media through the water inlet pipe to quickly cool the thick plate after forming. At the same time, the cooling chamber forms an S-shaped path, which increases the contact area between the cooling medium and the interior of the lower mold, thereby improving heat exchange efficiency.

[0014] 3. The utility model can monitor the temperature of the forming frame and the area near the enclosure in real time by setting the temperature probe hole. At the same time, by monitoring the temperature, the thermal state of the thick plate during the stamping process can be understood in time to ensure that the mold temperature is within a reasonable range, and prevent the degradation of material properties or damage to the mold due to overheating.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 5 As shown, a thick plate thermoforming mold includes a lower mold 1, a forming frame 2 and an upper mold 3. A boss 11 is provided on the top of the lower mold 1, and a forming groove 12 is opened on the boss 11. The forming groove 12 is used to form the final shape of the thick plate.

[0023] A first bevel 13 is provided on the outer peripheral wall of the boss 11; a panel 21 is provided in the forming frame 2, and a second bevel 22 is provided around the bottom of the panel 21, and the second bevel 22 is interlocked with the first bevel 13; a positioning block 23 is provided around the bottom of the forming frame 2, and a positioning groove 14 is provided around the top of the lower mold 1, and the positioning groove 14 is located on the outside of the boss 11, and the size of the positioning block 23 is adapted to the positioning groove 14; a stamping plate 31 is provided at the bottom of the upper mold 3, and the size of the stamping plate 31 is adapted to the internal size of the forming frame 2; the forming frame 2 is installed on the lower mold 1, wherein the top of the panel 21 and the top of the boss 11 are at the same height.

[0024] After the thick plate to be formed is heated to a suitable temperature, it is placed in the forming frame 2 , and pressure is applied to the upper mold 3 by a stamping device, so that the stamping plate 31 stamps the thick plate material into a shape that matches the forming groove 12 .

[0025] By interlocking the first bevel 13 and the second bevel 22, and cooperating the positioning block 23 and the positioning groove 14, the precise alignment between the forming frame 2 and the lower mold 1 is ensured, the forming accuracy is improved, and the stability of the mold during the stamping process is enhanced, and the mold is prevented from being deformed or damaged. After the stamping is completed, since the stamping plate 31 is adapted to the internal dimensions of the forming frame 2, the height of the enclosure 21 and the boss 11 are consistent, so that waste materials from the edge of the thick plate are accumulated around the enclosure 21. When taking out the formed thick plate, you only need to take out the forming frame 2 to bring out the thick plate, and then trim the thick plate, which improves the efficiency of thick plate disassembly and reduces damage to the formed thick plate, ensuring the integrity and aesthetics of the thick plate.

[0026] A cooling mechanism is provided inside the lower mold 1, and the cooling mechanism includes a water inlet pipe 41, a water outlet pipe 42 and a cooling chamber 4.

The cooling chamber 4 is provided inside the lower mold 1 and has an S-shaped design, and the two ends of the cooling chamber 4 are respectively connected to the water inlet pipe 41 and the water outlet pipe 42.

[0027] Cooling water or other cooling medium is introduced through the water inlet pipe 41 to quickly cool the formed thick plate. At the same time, the cooling cavity 4 forms an S-shaped path, which increases the contact area between the cooling medium and the interior of the lower mold 1, thereby improving the heat exchange efficiency.

[0028] Ear plates 5 are provided on the side walls of both sides of the forming frame 2 , and a grabbing groove 51 is provided at the bottom of the ear plates 5 .

[0029] By providing the ear plates 5 and the grabbing grooves 51 , it is convenient for the staff to remove the forming frame 2 from the lower mold 1 , thereby improving the efficiency of disassembling the formed thick plates.

[0030] The side wall of the forming frame 2 is provided with a temperature detection hole 24 , and the temperature detection hole 24 is provided above the enclosure 21 .

[0031] By setting the temperature probe hole 24, the temperature of the area near the forming frame 2 and the enclosure 21 can be monitored in real time. At the same time, by monitoring the temperature, the thermal state of the thick plate during the stamping process can be understood in time to ensure that the mold temperature is within a reasonable range, thereby preventing material performance degradation or mold damage due to overheating.

[0032] A mounting seat 32 is provided at the center of the top of the upper mold 3 .

[0033] The mounting base 32 is provided to facilitate connection between the stamping equipment and the upper die 3 , thereby improving stamping efficiency.

[0034] The working principle of the present invention is as follows: the thick plate to be formed is heated to a suitable temperature to ensure that the material has good plasticity and formability; the heated thick plate is placed in the forming frame 2 to ensure that the material can completely fill the forming groove 12. The upper mold 3 applies pressure through the stamping equipment, and the stamping plate 31 at the bottom thereof punches the thick plate material into a shape that matches the forming groove 12. The cooperation between the first bevel 13 and the second bevel 22, and the positioning block 23 and the positioning groove 14 ensures the stability and forming accuracy of the forming frame 2 and the lower mold 1 during the stamping process. At the same time, the height of the enclosure 21 is consistent with that of the boss 11, so that waste materials from the edge of the thick plate are accumulated around the enclosure 21. When taking out the formed thick plate, it is only necessary to take out the forming frame 2 to bring out the thick plate, and then trim the thick plate, thereby improving the efficiency of disassembly of the thick plate and reducing damage to the formed thick plate, thereby ensuring the integrity and aesthetics of the thick plate.
