[0044] With reference to Figure 1 and Figure 2 , the hot upper die according to the embodiments of the present application comprises a cooling plate 100, an upper die plate 300 and a first blocking member 210.

[0045] The cooling plate 100 is provided with a second channel 120, a third channel 130, a plurality of first channels 110 and a plurality of fourth channels 140, the first channels 110 extend along a first direction, the second channel 120 and the third channel 130 both extend along a second direction and penetrate at least one side of the cooling plate 100 in the second direction, the second channel 120 / third channel 130 forms an inlet 121 at the position where it penetrates the cooling plate 100, the second channel 120 / third channel 130 forms an outlet 122 at the position where it penetrates the cooling plate 100, the first direction intersects the second direction; the second channel 120 and the third channel 130 both communicate with at least two first channels 110, one end of the fourth channel 140 penetrates one side of the cooling plate 100 to form a fourth opening 141 on the cooling plate 100, and the other end communicates with the second channel 120 or the third channel 130 between two adjacent first channels 110;

[0046] The first blocking member 210 is arranged in the fourth channel 140 through the fourth opening 141, and can block the second channel 120 or the third channel 130, so that the cooling medium flowing into the first channel 110, the second channel 120 and the third channel 130 flows along an S-shaped path;

[0047] The upper die plate 300 is arranged on one side of the cooling plate 100.

[0048] It can be understood that the upper die plate 300 is used to combine with the lower die plate to hot-press the green compact to dry the green compact to form a dry compact, the cooling plate 100 is arranged on one side of the upper die plate 300, and the lifting driver is drivenly connected to the upper die plate 300 through the cooling plate 100, the lifting driver drives the cooling plate 100 to ascend and descend to drive the upper die plate 300 to ascend and descend, so that the upper die plate 300 combines with or separates from the lower die plate. The first channel 110, the second channel 120 and the third channel 130 in the cooling plate 100 can convey the cooling medium, so as to reduce the temperature of the upper die plate 300 transmitted to the lifting driver, reduce the failure rate of the lifting driver, and ensure the driving stability of the lifting driver to the upper die plate.

[0049] It can also be understood that, by arranging the first channel 110, the second channel 120, the third channel 130, the fourth channel 140 and the first blocking piece 210, the cooling medium entering the inside of the cooling plate 100 can flow along an S-shaped path, so as to improve the cooling effect of the cooling plate 100 on the upper die plate 300.

[0050] Specifically, in some embodiments, the cooling medium can enter the second channel 120 or the third channel 130 from the inlet 121, for example, the cooling medium enters the second channel 120 from the inlet 121, and then, since the first blocking piece 210 is arranged in the fourth channel 140, the second channel 120 at the position between the two first channels 110 is blocked, the cooling medium will turn into the first first channel 110a; when the cooling medium flows to the intersection of the first first channel 110a and the third channel 130, the cooling medium will turn into the third channel 130 from the first first channel 110a; when the cooling medium flows to the intersection of the third channel 130 and the second first channel 110b, since the first blocking piece 210 can block the position of the third channel 130 between the two first channels 110 or the third channel 130 has reached the end, the cooling medium will turn into the second first channel 110b from the third channel 130; when the cooling medium flows to the intersection of the second first channel 110b and the second channel 120, the cooling medium will turn into the second channel 120 from the second first channel 110b, and so on, so that the cooling medium flowing into the first channel 110, the second channel 120 and the third channel 130 can flow along an S-shaped path and flow out from the outlet 122, increase the flow path of the cooling medium in the cooling plate 100, increase the heat exchange time of the cooling medium and the upper die plate 300, and increase the effective heat exchange area between the cooling plate 100 and the upper die plate 300, thereby improving the cooling effect of the cooling plate 100.

[0051] It should also be understood that by extending the second channel 120 and the third channel 130 in the second direction and in communication with the plurality of first channels 110, and by extending the second channel 120 and the third channel 130 through the side of the cooling plate 100, the forming of the second channel 120 and the third channel 130 can be facilitated. Specifically, when forming the second channel 120 and the third channel 130, a drilling device can be inserted from one side of the cooling plate 100, and pass through the plurality of first channels 110 to form the second channel 120 and the third channel 130 in communication with the first channels 110, respectively. In order to allow the cooling medium to flow along the S-shaped path, a first blocking member 210 is needed to be arranged at a position where the second channel 120 or the third channel 130 is located between two first channels 110, so as to cut off the second channel 120 or the third channel 130, and allow the cooling medium to flow along the preset path. By arranging the fourth channel 140 in communication with the position where the second channel 120 or the third channel 130 is located between two first channels 110, the end of the first blocking member 210 is inserted into the intersection of the second channel 120 or the third channel 130 and the fourth channel 140, the first blocking member 210 can cut off the second channel 120 or the third channel 130, and the fourth channel 140 extends through one side of the cooling plate 100 and forms a fourth opening 141, the first blocking member 210 can be inserted into the fourth channel 140 through the fourth opening 141, which facilitates the forming of the fourth channel 140 and the installation of the first blocking member 210.

[0052] Specifically, the cooling medium can be water, oil, or cold air, etc.

[0053] Specifically, the upper mold plate 300 is provided with a heating pipe to heat the upper mold plate 300.

[0054] Specifically, the first direction is perpendicular to the second direction.

[0055] Referring to Figure 2 According to some embodiments of the present application, the second channel 120 is provided with two second channels 120, one of which is in communication with a portion of the first channels 110, and the other of which is in communication with another portion of the first channels 110, and the two second channels 120 are arranged at intervals at adjacent ends.

[0056] It can be understood that by setting two second channels 120 and letting one of the second channels 120 communicate with one part of the first channels 110 and the other second channel 120 communicate with the other part of the first channels 110, and letting the two second channels 120 be spaced apart, the first blocking member 210 does not need to be additionally arranged between the two first channels 110 to divert the cooling medium, thereby saving production cost. It can also be understood that the cooling plate 100 has a certain length, and by setting two second channels 120, the drilling equipment can be drilled from opposite sides of the cooling plate 100 during the formation of the two second channels 120, thereby avoiding the possibility of the drilling equipment drilling too deep and breaking the drill, and improving the forming precision of the second channels 120.

[0057] With reference to Figure 2 According to some embodiments of the present application, the third channel 130 is provided with two third channels 130, one of which communicates with one part of the first channels 110 and the other third channel 130 communicates with the other part of the first channels 110, and the adjacent ends of the two third channels 130 are spaced apart.

[0058] It can be understood that by setting two third channels 130 and letting one of the third channels 130 communicate with one part of the first channels 110 and the other third channel 130 communicate with the other part of the first channels 110, and letting the two third channels 130 be spaced apart, the first blocking member 210 does not need to be additionally arranged between the two first channels 110 to divert the cooling medium, thereby saving production cost. It can also be understood that the cooling plate 100 has a certain length, and by setting two third channels 130, the drilling equipment can be drilled from opposite sides of the cooling plate 100 during the formation of the two third channels 130, thereby avoiding the possibility of the drilling equipment drilling too deep and breaking the drill, and improving the forming precision of the third channels 130.

[0059] It should be noted that in order to allow the cooling medium to flow normally, the spacing positions between the two second channels 120 and the spacing positions between the two third channels 130 are staggered, i.e. the spacing positions are located between two different first channels 110.

[0060] With reference to Figure 2 According to some embodiments of the present application, the first channel 110 penetrates at least one side of the cooling plate 100 in the first direction of the cooling plate 100 to form a first opening 111 on the cooling plate 100.

[0061] It can be understood that by letting the first channel 110 penetrate at least one side of the cooling plate 100 and form the first opening 111, the formation of the first channel 110 can be facilitated. For example, during the formation of the first channel 110, the drilling equipment can be drilled along one side of the cooling plate 100 in the first direction to form the first channel 110.

[0062] With reference to Figure 2 , according to some embodiments of the present application, the first opening 111 is closed by a second closing member 220.

[0063] It can be understood that the first opening 111 is closed by the second closing member 220 to avoid the cooling medium flowing out of the first opening 111.

[0064] With reference to Figure 2 , according to some embodiments of the present application, the first channel 110 extends through both sides of the cooling plate 100 in the first direction.

[0065] It can be understood that the first channel 110 extends through both sides of the cooling plate 100 in the first direction, which can further facilitate the forming of the first channel 110. Specifically, in the process of forming the first channel 110, the drilling equipment can be first drilled from one side of the cooling plate 100 in the first direction to form one section of the first channel 110, and then the drilling equipment can be drilled from the other side of the cooling plate 100 in the first direction to form another section of the first channel 110 and communicate with the one section of the first channel 110, so as to form the first channel 110.

[0066] It can also be understood that in the process of forming the first channel 110, the drilling equipment can also be drilled from one side of the cooling plate 100 in the first direction and drilled out from the other side of the cooling plate 100 in the first direction to directly complete the machining of the first channel 110. After the drill bit of the drilling equipment is seen to drill out, it indicates that the first forming channel is completed machining, which is beneficial to observing the machining state of the first channel 110.

[0067] With reference to Figure 2 , according to some embodiments of the present application, the fourth channel 140 extends along the first direction.

[0068] It can be understood that by making the fourth channel 140 also extend along the first direction, the fourth channel 140 is parallel to the first channel 110, which can facilitate the arrangement of the drilling equipment. In the process of forming the first channel 110 and the fourth channel 140, the drilling equipment only needs to be translated, without the need to adjust the angle of the drilling equipment. Moreover, it can avoid the first channel 110 and the fourth channel 140 communicating, thereby avoiding affecting the correct flow of the cooling medium.

[0069] In summary, one of the specific structures of the cooling plate 100 in the hot-pressing upper die according to the present application is as follows:

[0070] With reference to Figure 2The first channel 110 is provided with six first channels 110, which are defined as a first first channel 110a, a second first channel 110b, a third first channel 110c, a fourth first channel 110d, a fifth first channel 110e and a sixth first channel 110f, and each of the first channels 110 forms a first opening 111 on the two sides of the cooling plate 100 along the first direction, and each of the first openings 111 is blocked by the second blocking member 220.

[0071] The second channel 120 is provided with two second channels 120, which are defined as a first second channel 120a and a second second channel 120b, and the two second channels 120 respectively penetrate the opposite sides of the cooling plate 100 along the second direction. The first second channel 120a forms an inlet 121 on the cooling plate 100, and the second second channel 120b forms an outlet 122 on the cooling plate 100. The inlet 121 is used for entering the cooling medium, and the outlet 122 is used for flowing out the cooling medium. The first second channel 120a is in communication with the first first channel 110a, the second first channel 110b and the third first channel 110c, and the second second channel 120b is in communication with the fourth first channel 110d, the fifth first channel 110e and the sixth first channel 110f. The two second channels 120 are spaced apart at the close end, and the spacing position of the two second channels 120 is between the third first channel 110c and the fourth first channel 110d.

[0072] The third channel 130 is provided with two third channels 130, which are defined as a first third channel 130a and a second third channel 130b, and the two third channels 130 respectively penetrate the opposite sides of the cooling plate 100 along the second direction. The two third channels 130 form a third opening 131 on the opposite sides of the cooling plate 100 at the far end, and the third blocking member 230 is arranged at the third opening 131. The first third channel 130a is in communication with the first first channel 110a and the second first channel 110b, and the second third channel 130b is in communication with the third first channel 110c, the fourth first channel 110d, the fifth first channel 110e and the sixth first channel 110f. The two third channels 130 are spaced apart at the close end, and the spacing position of the two third channels 130 is between the second first channel 110b and the third first channel 110c.

[0073] The fourth passages 140 are provided with three passages, which are defined as a first fourth passage 140a, a second fourth passage 140b and a third fourth passage 140c, and the first blocking members 210 are provided with three members, each of which is arranged in one of the fourth passages 140. The first fourth passage 140a is connected to the second passage 120 at a position between the first first passage 110a and the second first passage 110b, the second fourth passage 140b is connected to the third passage 130 at a position between the fourth first passage 110d and the fifth first passage 110e, and the third fourth passage 140c is connected to the second passage 120 at a position between the fifth first passage 110e and the sixth first passage 110f.

[0074] Thus, the cooling medium flows into the inlet 121 and enters the first second passage 120a and moves in the second direction. Due to the first blocking member 210 in the first fourth passage 140a, the cooling medium is diverted into the first first passage 110a. Then, the cooling medium enters the first third passage 130a and, due to the interval between the first third passage 130a and the second third passage 130b, the cooling medium enters the second first passage 110b. Subsequently, the cooling medium enters the second half of the first second passage 120a and, due to the interval between the first second passage 120a and the second second passage 120b, the cooling medium enters the third first passage 110c. Then, the cooling medium enters the second third passage 130b and, due to the first blocking member 210 in the second fourth passage 140b, the cooling medium is diverted into the fourth first passage 110d. Subsequently, the cooling medium enters the second second passage 120b and, due to the first blocking member 210 in the third fourth passage 140c, the cooling medium is diverted into the fifth first passage 110e. Then, the cooling medium enters the second half of the second third passage 130b, and then enters the sixth first passage 110f, and finally enters the second half of the second second passage 120b and flows out of the outlet 122, so that the cooling medium flows along an S-shaped path.

[0075] Referring to Figure 3 According to some embodiments of the present application, the first blocking member 210 comprises a head portion 211, a blocking portion 212 and a sealing ring 213, the head portion 211 is arranged at one end of the blocking portion 212, the blocking portion 212 is arranged in the fourth passage 140, the head portion 211 is partially arranged in the fourth passage 140 and connected to the inner wall of the fourth passage 140, and the head portion 211 is partially arranged outside the fourth passage 140 and abuts against the outer side of the cooling plate 100 through the sealing ring 213.

[0076] It can be understood that the end of the plugging part 212 can penetrate into the second channel 120 or the third channel 130 to cut off the second channel 120 or the third channel 130, the head part 211 is screwed or clamped with the inner wall of the fourth channel 140 to fix the plugging part 212 in the fourth channel 140, and the sealing ring 213 is arranged between the head part 211 and the outer side of the cooling plate 100 to enable the first plugging part 210 to plug the fourth opening 141 to prevent the cooling medium from leaking out of the fourth opening 141.

[0077] Referring to Figure 4 , Figure 5 and Figure 6 , according to some embodiments of the present application, the upper mold plate 300 is formed with a suction channel 310 and a blowing channel 320, the suction channel 310 forms a suction port 311 on one side of the upper mold plate 300, and the blowing channel 320 forms a blowing port 321 on one side of the upper mold plate 300, the suction pipe 400 and the blowing pipe 500 are both arranged through the upper mold plate 300, and the suction pipe 400 is in communication with the suction channel 310, and the blowing pipe 500 is in communication with the blowing channel 320.
