DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0023] The hot forming technology is to put the steel plate into a heating furnace, heat it to about 950 degrees, make it uniformly austenitized, and then quickly transfer it to the hot forming mold of the press 100, and quickly cool it and stamp it to obtain a high-strength structural part with a uniform martensitic structure. In order to achieve rapid cooling of the hot formed parts, it is necessary to open a cooling water channel on the mold, and the cooling water circulates in the water channel. At the same time, an external cooling water circulation system is required to supply cooling water to the mold. In addition, after some parts are formed, a hydraulic cylinder is needed to push the parts out of the mold to facilitate the unloading mechanism to take out the formed parts, so an oil channel is also required on the mold. For a press 100, it is often necessary to match multiple models of molds to adapt to different parts or process steps. When replacing the mold, it is necessary to disconnect the oil and water circuits between the mold and the press 100 and disassemble the mold; during the mold installation process, it is necessary to reconnect the oil and water circuits between the mold and the press 100 to facilitate the mold to mold and demold the workpiece.

[0024] At present, the oil circuit and the water circuit between the upper die bed 110 and the upper die base 200 of the press machine 100 are manually connected by the staff through additional pipelines, which greatly increases the workload of the workers and reduces the efficiency of mold replacement.

[0025] Therefore, please refer to the mold provided in the embodiment of this application. Figures 1 to 5, including a press 100 and an upper die base 200, the press 100 includes an upper die bed 110, the upper die bed 110 is provided with a first connector 120, the upper die base 200 is provided with a second connector 210, one of the first connector 120 and the second connector 210 is a male connector, and the other is a female connector, the upper die bed 110 can move toward the upper die base 200 to allow the first connector 120 and the second connector 210 to be plugged in. It can be understood by those skilled in the art that when the first connector 120 is a male connector, the second connector 210 is a female connector; conversely, when the first connector 120 is a female connector, the second connector 210 is a male connector. The specific selection can be set by those skilled in the art according to needs. The embodiments of the present application are not limited. Specifically in the embodiment of the present application, the first connector 120 is preferably a male connector, and the second connector 210 is preferably a female connector, that is, a male connector is provided on the upper mold bed 110, and a female connector is provided on the upper mold base 200.

[0026] Those skilled in the art may know that the press 100 has a hydraulic system, which can drive the upper die bed 110 to move up and down. Therefore, in the embodiment of the present application, when the upper die base 200 is installed on the upper die bed 110, the upper die base 200 is placed under the upper die bed 110, and then the upper die bed 110 is moved down to fit the upper die base 200, and then the upper die base 200 is fastened to the upper die bed 110. In this process, since the upper mold bed 110 is provided with a first connector 120 and the upper mold base 200 is provided with a second connector 210, when the upper mold bed 110 moves downward, the first connector 120 will be driven to move downward, and when the upper mold bed 110 is in contact with the upper mold base 200, the first connector 120 is inserted into the second connector 210. In this way, the pipe connection between the upper mold base 200 and the upper mold bed 110 is realized. There is no need for workers to provide additional adapter tubes for connection. Instead, the pressure during the contact process between the upper mold bed 110 and the upper mold base 200 is used to connect the first connector 120 and the second connector 210, thereby reducing the work intensity of workers and improving the efficiency of mold replacement.

[0027] Please refer to Figure 2 and Figure 3In some embodiments, the upper die bed 110 is provided with a mounting groove 111, the press 100 further includes a first mounting plate 130, the first mounting plate 130 is fixed to the mounting groove 111, and the first connector 120 is fixed to the first mounting plate 130; the upper die base 200 includes a body and a second mounting plate 220, the body is provided with a mounting platform 201, the second mounting plate 220 is fixed to the mounting platform 201, and the second connector 210 is fixed to the second mounting plate 220. In this embodiment, by providing the first mounting plate 130 and the second mounting plate 220, the first connector 120 and the second connector 210 can be easily fixed, and by providing the mounting groove 111 and the mounting platform 201, a positioning function can be played. It can be understood by those skilled in the art that, during the installation of the first connector 120, the first connector 120 can be first installed on the first mounting plate 130, and then the first mounting plate 130 can be fixed in the mounting groove 111. Similarly, the second connector 210 can be first installed on the second mounting plate 220, and then the second mounting plate 220 can be fixed on the mounting platform 201. Those skilled in the art can also understand that the first connector 120 is installed on the first mounting plate 130, and the second connector 210 is installed on the second mounting plate 220, which are both prior arts and will not be described in detail here.

[0028] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the mold further includes a guide device 300, the guide device 300 includes a first guide member 310 and a second guide member 320, one of the first guide member 310 and the second guide member 320 is a guide column, and the other is a guide sleeve, the first guide member 310 is fixed to the first mounting plate 130, the second guide member 320 is fixed to the second mounting plate 220, the upper mold bed 110 moves toward the upper mold base 200, and the first guide member 310 can cooperate with the second guide member 320 to accurately plug the first connector 120 and the second connector 210. By setting the guide device 300, it can be ensured that the first connector 120 and the second connector 210 are accurately docked and accurately installed, thereby ensuring that the concentricity of the first connector 120 and the second connector 210 will not be offset to cause leakage.

[0029] Please continue to refer to Figure 2 and Figure 3In the embodiment of the present application, the first guide member 310 is preferably a guide post, and the second guide member 320 is preferably a guide sleeve, and the diameter of the guide post at one end close to the upper mold base 200 is slightly smaller, and / or the inner diameter of the guide sleeve at the side close to the upper mold bed 110 is slightly larger, so that the guide post can be easily inserted into the guide sleeve. The guide post and the guide sleeve are both prior art and will not be described in detail here. It can be understood by those skilled in the art that there can be two guide devices 300, and the provision of two guide devices 300 can increase the accuracy of positioning. In addition, it can be understood by those skilled in the art that during the downward movement of the upper mold bed 110, the guide post is first inserted into the guide sleeve, and at this time the first connector 120 and the second connector 210 are not in contact. When the upper mold bed 110 moves further downward, the guide post and the guide sleeve play a guiding role, so that the first connector 120 and the second connector 210 can be accurately docked.

[0030] In some embodiments, the number of the first mounting plates 130 is multiple, and the first connector 120 is fixed on each of the multiple first mounting plates 130; the upper mold bed 110 is provided with multiple mounting grooves 111, and the first mounting plates 130 are fixed in the mounting grooves 111 one by one. It is known to those skilled in the art that, since a press 100 can be installed with multiple different molds, that is, an upper mold bed 110 can correspond to multiple different upper mold bases 200, and the positions of the water pipes and / or oil pipe interfaces of different upper mold bases 200 are not necessarily the same; that is, the positions of the second connectors 210 on different upper mold bases 200 are not exactly the same, therefore, in the embodiment of the present application, by arranging multiple first mounting plates 130 on the upper mold bed 110 and presetting the first connector 120 on the first mounting plates 130, it is possible to facilitate the adaptation of molds of different models and increase the applicability of the press 100.

[0031] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the first connector 120 includes an oil circuit male connector 121; the second connector 210 includes an oil circuit female connector 211, and the oil circuit male connector 121 corresponds to the oil circuit female connector 211. It can be understood by those skilled in the art that there can be multiple oil circuit male connectors 121, and there can also be multiple corresponding oil circuit female connectors 211, and multiple oil circuit male connectors 121 correspond to multiple oil circuit female connectors 211 one by one. The specific number of oil circuit male connectors 121 and oil circuit female connectors 211 can be determined by those skilled in the art as needed.

[0032] In some embodiments, the press 100 further includes an oil pipe, and the oil pipe is fixedly connected to one end of the oil circuit male connector 121 away from the oil circuit female connector 211. Furthermore, the oil pipe is a rigid oil pipe, such as a seamless steel pipe, etc. The use of a rigid oil pipe can facilitate the fixing of the oil pipe to the upper mold bed 110 to prevent the upper mold bed 110 from moving and causing the oil pipe to shake, thereby causing collisions between the oil pipe and other components and damaging the oil pipe. In the embodiment of the present application, the oil pipe can be connected to the oil circuit male connector 121 in advance, and when the upper mold bed 110 is replaced later, it does not need to be disassembled, thereby increasing the replacement efficiency.

[0033] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the first connector 120 includes a water channel male connector 122; the second connector 210 includes a water channel female connector 212, and the water channel male connector 122 corresponds to the water channel female connector 212. The press 100 also includes a water pipe, and the water pipe is fixedly connected to one end of the water channel male connector 122 away from the water channel female connector 212. It can be understood by those skilled in the art that the arrangement of the water channel female connector 212, the water channel male connector 122 and the water pipe can refer to the arrangement of the oil pipe, and will not be repeated here.

[0034] Please refer to Figure 4 and Figure 5 , those skilled in the art can understand that a plurality of oil circuit male connectors 121, a plurality of water circuit male connectors 122 and guide posts can be pre-installed on the first mounting plate 130. Obviously, by setting the first mounting plate 130, the integrated installation of the oil circuit male connectors 121, the water circuit male connectors 122 and the guide posts can also be facilitated. Correspondingly, by setting the second mounting plate 220, the installation of the oil circuit female connectors 211, the water circuit female connectors 212 and the guide sleeves can also be facilitated. Then, the first mounting plate 130 is fixed in the mounting groove 111, and the second mounting plate 220 is fixed to the mounting platform 201; then, the upper mold bed 110 is moved downward, so that the first mounting plate 130 approaches the second mounting plate 220, until the guide posts are first inserted into the guide sleeves, and then the upper mold bed 110 is further moved downward, and through the cooperation of the guide posts and guide sleeves, the oil circuit male connectors 121 and the oil circuit female connectors 211, and the water circuit male connectors 122 and the water circuit female connectors 212 are docked. In this process, the cooperation of the guide pin and guide sleeve ensures the concentricity of the oil circuit male head 121 and the oil circuit female head 211, and the water circuit male head 122 and the water circuit female head 212, avoiding oil and water leakage; and the docking process is achieved by moving the upper mold bed 110 downward under the action of the hydraulic system, without the need for workers to manually plug in, reducing the workload of workers.

[0035] In some embodiments, the press 100 further includes a switch valve, which is disposed at one end of the first connector 120 away from the second connector 210. By providing the switch valve, when the upper die base 200 needs to be disassembled from the upper die bed 110, the switch valve can be closed in advance before disassembly, thereby preventing the liquid in the water pipe or oil pipe from overflowing during the separation process of the first connector 120 and the second connector 210, thereby ensuring a clean environment.

[0036] Please refer to Figure 1 In some embodiments, the press 100 further includes a guide post 140, and the upper die bed 110 is disposed through the guide post 140, and the upper die bed 110 can move along the guide post 140. It is known to those skilled in the art that there are generally four guide posts 140, and the four guide posts 140 are located at the four corners of the upper die bed 110. By providing the guide posts 140, the movement of the upper die bed 110 can be facilitated.

[0037] Please continue to refer to Figure 1 , those skilled in the art can also understand that, the mold provided in the embodiment of the present application also includes a lower mold base 400, which is also fixed to the press 100 and is located below the upper mold bed 110. The upper mold bed 110 of the press 100 can drive the upper mold base 200 to move toward the lower mold base 400 to stamp the workpiece located between the upper mold base 200 and the lower mold base 400.
