[0047] Please refer to Figures 2 to 14 and in combination with Figure 1 This embodiment provides a product quenching device for quenching alloy plates in a high-temperature state. The product quenching device adopts an in-mold quenching method. Specifically, the product quenching device includes a lower mold 21 and an upper mold 22. Among them, the lower mold 21 is configured to place the product 1 to be quenched to expose the cavity 11 formed on the product 1. It can be understood that the product 1 mentioned in this embodiment is an alloy plate that has successively undergone casting, annealing, forging, and solution treatment. Moreover, the lower mold 21 is provided with a positioning module 211, and the positioning module 211 is configured to position the product 1. The upper mold 22 can move towards the lower mold 21 to complete mold closing, and the upper mold 22 and the lower mold 21 respectively press against both sides of the product 1 along the arrangement direction of the upper mold 22 and the lower mold 21, so that the product 1 is clamped between the upper mold 22 and the lower mold 21. Both the lower mold 21 and the upper mold 22 are provided with cooling passages, and the cooling passages are configured to circulate coolant to rapidly cool the product 1.

[0048] As described above, the lower die 21 and the upper die 22 are respectively provided with a first cooling passage 213 and a second cooling passage 222. Both the first cooling passage 213 and the second cooling passage 222 can circulate coolant, so as to rapidly cool the product 1. Exemplarily, in this embodiment, the cooling rate of the product 1 can reach 20 - 30 °C / S.

[0049] Moreover, the lower die 21 is provided with more than two first cooling passages 213. Exemplarily, in this embodiment, the lower die 21 is provided with three first cooling passages 213, so as to further ensure that the product quenching device can rapidly cool the product 1.

[0050] Of course, in other alternative embodiments, a cooling passage may also be provided only on the upper die 22 or the lower die 21, and this embodiment does not make specific restrictions on this.

[0051] In addition to the lower die 21 and the upper die 22, the product quenching device further includes an inner support mechanism 23. The inner support mechanism 23 is disposed on the side of the upper die 22 facing the lower die 21. The inner support mechanism 23 includes a first inner support module 231 and a second inner support module 232. When the upper die 22 moves towards the lower die 21 to complete mold closing, the first inner support module 231 and the second inner support module 232 can extend into the cavity 11. Moreover, the first inner support module 231 can press against the two side walls of the cavity 11 along the first direction, and the second inner support module 232 can press against the two side walls of the cavity 11 along the second direction. The first direction and the second direction are perpendicular, and both are perpendicular to the arrangement direction of the upper die 22 and the lower die 21. Taking the upper die 22 and the lower die 21 arranged in the vertical direction as an example, both the first direction and the second direction are horizontal directions, and the first direction and the second direction are perpendicular.

[0052] It should be noted that, in this embodiment, the product 1 is an alloy plate member with a cavity 11 provided therein. That is, in this embodiment, the cavity 11 is the structure of the alloy plate member itself, and the cavity 11 is formed on the plate surface of the alloy plate member. Of course, in other alternative embodiments, if the alloy plate member is a solid plate member, when initially forming the alloy plate member, a protrusion extending along the outer contour of the alloy plate member can be formed on the plate surface of the alloy plate member at the same time, so as to enclose and form the cavity 11 through the protrusion on the plate surface of the alloy plate member. That is, in other alternative embodiments, the product 1 may also be an alloy plate member that does not have a cavity 11 itself, but the cavity 11 is enclosed and formed by protrusions formed on its plate surface. This embodiment does not make specific restrictions on this. It can be understood that for an alloy plate member that does not have a cavity 11 itself, but the cavity 11 is enclosed and formed by protrusions formed on its plate surface, after quenching, the protrusions need to be removed.

[0053] Exemplarily, in this embodiment, the positioning module 211 includes a plurality of positioning blocks 2111. The plurality of positioning blocks 2111 are all fixed on the lower mold 21 and enclose a placement cavity for placing the product 1. The product 1 is placed in the placement cavity, and the plurality of positioning blocks 2111 support the outer periphery of the product 1, thereby positioning the product 1 to ensure that when the upper mold 22 and the lower mold 21 are clamped, the first inner support module 231 and the second inner support module 232 can accurately extend into the interior of the product 1.

[0054] As described above, in this embodiment, the product 1 is rapidly cooled by setting a coolant flowing along the cooling passage. Moreover, during the rapid cooling process, the first inner support module 231 and the second inner support module 232 press against the cavity wall of the cavity 11, thereby internally supporting the inner side wall of the product 1 to prevent the product 1 from shrinking during the rapid cooling process, so as to avoid the product 1 bulging and deforming due to large internal stress generated by itself, and further improve the qualification rate of the manufactured product 1.

[0055] Specifically, the lower mold 21 is provided with a placement surface 212, and the product 1 is placed on the placement surface 212 of the lower mold 21. It can be understood that the product 1 placed on the lower mold 21 is heated to a high temperature state. According to the characteristics of thermal expansion and contraction of materials, heating will cause the overall expansion of the product 1, that is, the product 1 placed on the lower mold 21 is the product 1 after bulging. It can be understood that since the thermal expansion characteristics of the material are controllable, the bulging rate of the product 1 heated to a high temperature state is controllable. Exemplarily, in this embodiment, the bulging rate of the product 1 heated to a high temperature state is controlled to 5%.

[0056] Based on the above, to ensure that the size of the product 1 after quenching meets the requirements, in this embodiment, based on the thermal expansion characteristics, the size of the product 1 obtained through casting, annealing, forging, and solution treatment is small. When the product 1 is subsequently heated to a high temperature state, the overall expansion of the product 1 occurs, and the size of the product 1 after bulging is the required size of the product 1. Subsequently, in this embodiment, the first inner support module 231 and the second inner support module 232 internally support the inner side wall of the product 1 to prevent the product 1 from shrinking during the rapid cooling process, so as to ensure that the size of the product 1 does not change during the cooling process, to ensure that the size of the cooled product 1 meets the requirements. Moreover, this embodiment can also avoid the generation of large internal stress in the product 1, thereby preventing the product 1 from bulging and deforming, and further improving the qualification rate of the manufactured product 1.

[0057] To enable the first inner support module 231 and the second inner support module 232 to internally support the inner sidewall of the product 1, in this embodiment, the first inner support module 231 includes two first inner support members 2311 oppositely arranged in the first direction, the second inner support module 232 includes two second inner support members 2321 oppositely arranged in the second direction, and the inner support mechanism 23 further includes a transmission member 233. The transmission member 233 is configured to drive the two first inner support members 2311 to move away from each other, and drive the two second inner support members 2321 to move away from each other, and all the first inner support members 2311 and all the second inner support members 2321 move synchronously, so that all the first inner support members 2311 and all the second inner support members 2321 can jointly internally support the inner sidewall of the product 1, so that the first inner support module 231 and the second inner support module 232 can limit the shrinkage of the product 1.

[0058] Thus, in this embodiment, the transmission member 233 can move in the third direction, and the third direction is perpendicular to the first direction and the second direction. Specifically, the third direction is the arrangement direction of the upper mold 22 and the lower mold 21.

[0059] Moreover, first inclined surfaces 2331 are provided on both sides of the transmission member 233 in the first direction, and second inclined surfaces 23111 are provided on the first inner support members 2311. The first inclined surfaces 2331 are adapted to and in contact with the second inclined surfaces 23111. That is, the transmission between the transmission member 233 and the two first inner support members 2311 is through a wedge structure. Specifically, one of the first inner support members 2311 is in transmission cooperation with one side of the transmission member 233 in the first direction through the second inclined surface 23111, and the other first inner support member 2311 is in transmission cooperation with the other side of the transmission member 233 in the first direction through the second inclined surface 23111. When the upper mold 22 moves towards the lower mold 21 and the two first inner support members 2311 extend into the cavity 11, the two first inner support members 2311 press against the product 1 in the third direction. After that, when the transmission member 233 moves in the third direction, the two first inner support members 2311 move away from each other in the first direction, so as to be able to press against the two side walls of the cavity 11 in the first direction respectively.

[0060] Moreover, third inclined surfaces 2332 are provided on both sides of the transmission member 233 along the second direction, and the second inner support member 2321 is provided with a fourth inclined surface 23211. The third inclined surface 2332 is adapted to and abuts against the fourth inclined surface 23211. That is, the transmission between the transmission member 233 and the two second inner support members 2321 is achieved through a wedge structure. Specifically, one of the second inner support members 2321 is in transmission cooperation with one side of the transmission member 233 along the second direction through the fourth inclined surface 23211, and the other second inner support member 2321 is in transmission cooperation with the other side of the transmission member 233 along the second direction through the fourth inclined surface 23211. When the upper die 22 moves towards the lower die 21 and the two second inner support members 2321 extend into the cavity 11, the two second inner support members 2321 press against the product 1 in the third direction. After that, when the transmission member 233 moves in the third direction, the two second inner support members 2321 move away from each other along the second direction, so as to be able to press against the two side walls of the cavity 11 along the second direction respectively.

[0061] From the above, in this embodiment, the transmission structure between the transmission member 233 and the first inner support module 231 and the second inner support module 232 is simple and compact, so as to facilitate pressing the wall of the cavity 11.

[0062] Moreover, among the mutually adapted first inclined surface 2331 and second inclined surface 23111, one is provided with a first dovetail groove 2333, and the other is provided with a first insert block 23112. Exemplarily, in this embodiment, the first inclined surface 2331 is provided with the first dovetail groove 2333, and the second inclined surface 23111 is provided with the first insert block 23112. The first insert block 23112 is fitted into the first dovetail groove 2333. Both the first dovetail groove 2333 and the first insert block 23112 extend along the direction parallel to the first inclined surface 2331 and the second inclined surface 23111, so as to be able to provide a guiding function for the transmission member 233 to drive the two first inner support members 2311 to move.

[0063] In addition, one of the first embedded block 23112 and the first dovetail groove 2333 is provided with a first protrusion 231121, and the other of the first embedded block 23112 and the first dovetail groove 2333 is provided with a first card groove 23331. Exemplarily, in this embodiment, the first embedded block 23112 is provided with a first protrusion 231121, and the first dovetail groove 2333 is provided with a first card groove 23331. The first protrusion 231121 is embedded in the first card groove 23331, and the outer wall of the first protrusion 231121 and the groove wall of the first card groove 23331 are parallel to the third direction. When the two first inner support members 2311 move back to back to respectively press the two side walls of the cavity 11 along the first direction, the first protrusion 231121 and the first card groove The bottom of the groove 23331 has a gap along the first direction. Thus, when the upper mold 22 moves away from the lower mold 21, the first inner support member 2311 can slide along the first inclined surface 2331 toward the side away from the upper mold 22, and the gap formed between the first protrusion 231121 and the bottom of the first groove 23331 is eliminated. After the gap formed between the first protrusion 231121 and the bottom of the first groove 23331 is eliminated, the first protrusion 231121 is pressed against the bottom of the first groove 23331 to limit the first inner support member 2311 from continuing to slide along the first inclined surface 2331, thereby ensuring that the first embedment block 23112 will not be detached from the first dovetail groove 2333, and further ensuring that the first inner support member 2311 will not be detached from the transmission member 233.

[0064] When the upper mold 22 moves toward the lower mold 21 and the transmission member 233 drives the two first inner support members 2311 to move oppositely along the first direction, as the first inner support members 2311 move along the first direction, a gap is re-formed between the first protrusion 231121 and the bottom of the first slot 23331 along the first direction.

[0065] Correspondingly, among the matching third bevel 2332 and fourth bevel 23211, one is provided with a second dovetail groove 2334, and the other is provided with a second embedment block 23212. By way of example, in this embodiment, the third bevel 2332 is provided with a second dovetail groove 2334, and the fourth bevel 23211 is provided with a second embedment block 23212. The second embedment block 23212 is embedded in the second dovetail groove 2334. Both the second dovetail groove 2334 and the second embedment block 23212 extend in a direction parallel to the third bevel 2332 and the fourth bevel 23211, thereby providing a guiding effect for the transmission member 233 to drive the two second inner support members 2321 to move.

[0066] In addition, one of the second embedded block 23212 and the second dovetail groove 2334 is provided with a second protrusion 232121, and the other of the second embedded block 23212 and the second dovetail groove 2334 is provided with a second card groove 23341. Exemplarily, in this embodiment, the second embedded block 23212 is provided with a second protrusion 232121, and the second dovetail groove 2334 is provided with a second card groove 23341. The second protrusion 232121 is embedded in the second card groove 23341, and the outer wall of the second protrusion 232121 and the groove wall of the second card groove 23341 are parallel to the third direction. When the two second inner support members 2321 move back to back to respectively press the two side walls of the cavity 11 along the second direction, the second protrusion 232121 and the second card groove The bottom of the groove 23341 has a gap along the second direction. Thus, when the upper mold 22 moves away from the lower mold 21, the second inner support member 2321 can slide along the third inclined surface 2332 toward the side away from the upper mold 22, and the gap formed between the second protrusion 232121 and the bottom of the second groove 23341 is eliminated. After the gap formed between the second protrusion 232121 and the bottom of the second groove 23341 is eliminated, the second protrusion 232121 presses against the bottom of the second groove 23341 to limit the second inner support member 2321 from continuing to slide along the third inclined surface 2332, thereby ensuring that the second embedment block 23212 will not detach from the second dovetail groove 2334, and further ensuring that the second inner support member 2321 will not detach from the transmission member 233.

[0067] When the upper mold 22 moves toward the lower mold 21 and the transmission member 233 drives the two second inner support members 2321 to move oppositely along the second direction, as the second inner support members 2321 move along the second direction, a gap is re-formed between the second protrusion 232121 and the bottom of the second slot 23341 along the second direction.

[0068] It is worth noting that, in addition to the mounting block 221, the upper mold 22 also includes a sleeve block 223, which is mounted on the side of the mounting block 221 facing the lower mold 21 and surrounds the outer periphery of the inner support mechanism 23, while the first inner support member 2311, the second inner support member 2321 and the transmission member 233 extend out of the sleeve block 223 along the third direction, and the sleeve block 223 can limit the first inner support member 2311 from disengaging from the transmission member 233 along the first direction, and limit the second inner support member 2321 from disengaging from the transmission member 233 along the second direction.

[0069] Further, in this embodiment, the upper mold 22 includes a mounting block 221. The transmission member 233 can move along the third direction together with the upper mold 22. Specifically, the inner support mechanism 23 is installed on the side of the mounting block 221 facing the lower mold 21, and the transmission member 233 is fixedly connected to the mounting block 221. Based on the content described above, in this embodiment, the two first inner support members 2311 and the two second inner support members 2321 are both suspended on the transmission member 233. Under the action of the first dovetail groove 2333, the first insert block 23112, the first convex block 231121 and the first card slot 23331, the two first inner support members 2311 will not detach from the transmission member 233. Correspondingly, under the action of the second dovetail groove 2334, the second insert block 23212, the second convex block 232121 and the second card slot 23341, the two second inner support members 2321 will not detach from the transmission member 233.

[0070] As described above, in this embodiment, when the upper mold 22 moves towards the lower mold 21, the two first inner support members 2311 and the two second inner support members 2321 extend into the cavity 11. Then, the two first inner support members 2311 and the two second inner support members 2321 first press against the product 1 in the third direction. After that, the transmission member 233 continues to move with the upper mold 22, so that the transmission member 233 can drive the two first inner support members 2311 to move away from each other in the first direction, and drive the two second inner support members 2321 to move away from each other in the second direction, until the upper mold 22 and the lower mold 21 are closed and respectively press against both sides of the product 1 along the arrangement direction of the upper mold 22 and the lower mold 21. At this time, the two first inner support members 2311 respectively press against the two side walls of the cavity 11 in the first direction, and the two second inner support members 2321 respectively press against the two side walls of the cavity 11 in the second direction.

[0071] In addition, in this embodiment, a stud 241 is correspondingly arranged on the side of all the first inner support members 2311 and all the second inner support members 2321 away from the placement surface 212. The stud 241 extends along the third direction and is movably inserted into the mounting block 221 along the third direction, and has a first working position extending out of the mounting block 221 and a second working position retracted into the mounting block 221. A spring 242 is arranged on the side of the stud 241 away from the placement surface 212 along its extending direction. The spring 242 is configured to drive the stud 241 to stop at the first working position.

[0072] Specifically, when the upper mold 22 moves downward toward the lower mold 21, the two first inner support members 2311 and the two second inner support members 2321 first extend into the cavity 11. After that, the two first inner support members 2311 and the two second inner support members 2321 press against the product 1 in the third direction. Subsequently, as the mounting block 221 and the transmission member 233 continue to move in the third direction, on the one hand, the first inner support member 2311 and the second inner support member 2321 gradually approach the mounting block 221 in the third direction. At the same time, the stud 241 gradually retracts into the mounting block 221, that is, the stud 241 switches from the first working position to the second working position, and the spring 242 is compressed and deformed. On the other hand, under the pushing of the transmission member 233, the two first inner support members 2311 move away from each other in the first direction, and the two second inner support members 2321 move away from each other in the second direction until the sleeve block 223 presses against the side of the product 1 away from the lower mold 21 along the arrangement direction of the upper mold 22 and the lower mold 21. At this time, the two first inner support members 2311 respectively press against the two side walls of the cavity 11 in the first direction, and the two second inner support members 2321 respectively press against the two side walls of the cavity 11 in the second direction.

[0073] After the quenching operation is completed, the upper mold 22 moves away from the lower mold 21 and drives the two first inner support members 2311 and the two second inner support members 2321 to move toward the side away from the lower mold 21. The spring 242 then restores its deformation, thereby driving the stud 241 to reset from the second working position to the first working position. At the same time, under the drive of the spring 242 and the stud 241, the first inner support member 2311 slides along the first inclined surface 2331 to reset. Specifically, the first inner support member 2311 moves away from the mounting block 221 in the third direction and moves toward the side closer to the transmission member 233 in the first direction. Correspondingly, the second inner support member 2321 slides along the third inclined surface 2332 to reset. Specifically, the second inner support member 2321 moves away from the mounting block 221 in the third direction and moves toward the side closer to the transmission member 233 in the second direction, so that the first inner support member 2311 and the second inner support member 2321 are reset to their initial positions, which is convenient for inner supporting the product 1 when quenching the next product 1.

[0074] As described above, a plurality of studs 241 are correspondingly arranged on the sides of all the first inner support members 2311 and all the second inner support members 2321 away from the placement surface 212, and springs 242 are correspondingly arranged for all the studs 241. Thus, when the upper mold 22 moves away from the lower mold 21 and drives the two first inner support members 2311 and the two second inner support members 2321 to move toward the side away from the lower mold 21, the first inner support member 2311 can slide as a whole along the first inclined surface 2331 to reset. Correspondingly, the second inner support member 2321 can slide as a whole along the third inclined surface 2332 to reset.

[0075] Furthermore, in this embodiment, two corners 111 are formed between any one side wall of the cavity 11 along the first direction and the two side walls of the cavity 11 along the second direction. That is, in this embodiment, the cavity 11 is rectangular and has four corners 111. Correspondingly, two first support portions 234 are provided on one side of the transmission member 233 along the first direction, and the two first support portions 234 are spaced apart along the second direction. Specifically, the two first support portions 234 are provided on both sides of the transmission member 233 along the second direction. Two second support portions 235 are provided on the other side of the transmission member 233 along the first direction, and the two second support portions 235 are spaced apart along the second direction. Specifically, the two second support portions 235 are provided on both sides of the transmission member 233 along the second direction. The two first support portions 234 and the two second support portions 235 can respectively fit with the four corners 111, so as to cooperate with the first inner support module 231 and the second inner support module 232 to internally support the inner side wall of the product 1 together, thereby realizing the support of all parts of the inner side wall of the product 1, so as to more fully prevent the product 1 from shrinking during the rapid cooling process, thereby further avoiding the generation of large internal stresses in the product 1, and further preventing the product 1 from bulging and deforming.

[0076] Based on the above, in this embodiment, a fifth inclined surface 23113 and a sixth inclined surface 23114 are respectively provided on both sides of the first inner support member 2311 along the second direction, a seventh inclined surface 23213 and an eighth inclined surface 23214 are respectively provided on both sides of the second inner support member 2321 along the first direction, a ninth inclined surface 2341 and a tenth inclined surface 2342 are provided on the first support portion 234, and an eleventh inclined surface 2351 and a twelfth inclined surface 2352 are provided on the second support portion 235.

[0077] Moreover, one of the first inner support members 2311 is provided between the two first support portions 234, and the two ninth inclined surfaces 2341 respectively fit and are adapted to the fifth inclined surface 23113 and the sixth inclined surface 23114. Another first inner support member 2311 is provided between the two second support portions 235, and the two eleventh inclined surfaces 2351 respectively fit and are adapted to the fifth inclined surface 23113 and the sixth inclined surface 23114.

[0078] In addition, a second inner support member 2321 is disposed between the first support portion 234 and the second support portion 235 provided on the same side, and the tenth inclined surface 2342 and the twelfth inclined surface 2352 are respectively adapted to and in contact with the seventh inclined surface 23213 and the eighth inclined surface 23214, so that the first support portion 234 can achieve transmission cooperation with the first inner support member 2311 and the second inner support member 2321 adjacent thereto, and the second support portion 235 can achieve transmission cooperation with the first inner support member 2311 and the second inner support member 2321 adjacent thereto. Furthermore, it is ensured that after the two first inner support members 2311 move away from each other and the two second inner support members 2321 move away from each other, the two first support portions 234, the two second support portions 235, the first inner support module 231 and the second inner support module 232 can support all parts of the inner side wall of the product 1.

[0079] Furthermore, it is worth noting that in order to facilitate the separation of the product 1 from the inner support mechanism 23, in this embodiment, a thirteenth inclined surface 112 is provided on the wall of the cavity 11. Thus, in this embodiment, the outer peripheries of the two first inner support members 2311, the two second inner support members 2321, the two first support portions 234 and the two second support portions 235 can jointly form a support wall that imitates the wall of the cavity 11. Moreover, along the third direction, from the side close to the upper die 22 to the side away from the upper die 22, the side of the support wall away from the upper die 22 inclines towards the central portion of the transmission member 233. When the two first support portions 234, the two second support portions 235, the first inner support module 231 and the second inner support module 232 support all parts of the inner side wall of the product 1, the side of the support wall away from the upper die 22 can be directly opposite to the thirteenth inclined surface 112. As a result, the bulging rate of the product 1 heated to a high temperature state does not need to be too large, thereby facilitating the preparation of alloy plates.

[0080] In addition, it is worth noting that the second cooling passage 222 includes a first branch 2221, a second branch 2222 and a third branch 2223. The first branch 2221, the second branch 2222 and the third branch 2223 are all provided on the sleeve block 223. Among them, the first branch 2221 and the third branch 2223 are respectively the liquid inlet branch and the liquid outlet branch, and the second branch 2222 is connected between the first branch 2221 and the third branch 2223 and surrounds the outer periphery of the inner support mechanism 23, so as to further achieve rapid cooling of the product 1.
