The guide plate pad 152 is configured as a frame structure whose central opening is connected to the fifth through groove 121.

[0034] Among them, the upper punch plate pad 142 and the guide plate pad 152 can not only facilitate the installation of the upper punch heating seat 14 and the upper punch heating plate 15 and increase the stability of the structure, but also can isolate the heat of the upper punch heating seat 14 and the upper punch heating plate 15 from heat exchange with the upper punch plate 11 and the upper punch guide plate 12, thereby improving the service life of the hot pressing die frame.

[0035] Preferably, the upper punch assembly 1 may also include a third heating rod 143 and a fourth heating rod 153.

[0036] In order to facilitate the transmission connection between the upper punch plate 11 and the upper driving device of the external powder molding press, the upper punch assembly 1 can also include an upper pull seat 18 and two upper punch blocks 19. The upper pull seat 18 is fixedly arranged upward on the top surface of the upper punch plate 11, and the upper punch blocks 19 are relatively fixedly arranged on the top of the upper punch plate 11 and are clamped with the top surfaces of the two side edges of the upper pull seat 18 to improve the load-bearing capacity of the entire mold frame.

[0037] like Figure 7 As shown, the upper punch plate 11, the upper punch guide plate 12, the middle template 3 and the fixed plate 4 can be provided with condensate flow channels inside, and the outer walls of the upper punch plate 11, the upper punch guide plate 12, the middle template 3 and the fixed plate 4 are provided with more than two water transport joints 7 connected to their respective condensate flow channels.

[0038] During the cooling process after the product is molded or formed, the condensed water flow channel in each plate can be connected to the water pipe through its corresponding water joint 7, so that the condensed water can flow effectively in each plate, thereby improving the molding efficiency of the powder molded product.

[0039] Preferably, in order to extend the service life of the mold frame and ensure its stable and reliable operation during the hot pressing process, it can also include a front waterproof plate 122 of the upper punch guide plate and a front waterproof plate 32 of the middle template. The front waterproof plate 122 of the upper punch guide plate is fixedly arranged on a side surface of the upper punch guide plate 12 away from its water transport joint 7, and the front waterproof plate 32 of the middle template is fixedly arranged on a side wall of the middle template 3 away from its water transport joint 7.

[0040] The working principle of this embodiment is as follows:

[0041] First, the entire core rod module 5 is fixedly installed on the middle mold plate 3 and the fixed plate 4, and then the first heating rod 23 and the second heating rod 634 respectively heat the mother mold 2, the lower punch heating seat 63 and the lower punch 61, and the third heating rod 143 and the fourth heating rod 153 can heat the upper punch heating seat 14, the upper punch heating plate 15 and the upper punch 16. The output part of the lower driving device of the external powder molding press passes through the core rod bottom plate 54, the third through groove 41 and the second through groove 631 respectively, and is connected to the bottom of the core rod mounting plate 53 through the output part, and drives the core rod mounting plate 53 and the core rod 51 to move upward and have a distance away from the mother mold 2. At this time, the operator or the manipulator can place products such as inductor coils on the mother mold 2, and the coil body of the inductor coil is located at the opening of the molding hole 21 of the mother mold 2, and then fill the molding hole 21 with powder manually or by the powder feeding device of the powder molding press. At the same time, the external powder molding press The upper driving device of the machine is respectively connected to the upper pull seat 18 for transmission and drives the upper punch plate 11 and the upper punch guide plate 12 to move downward. When the bottom of the upper punch guide plate 12 contacts the top of the mother mold 2, the upper driving device continues to drive the upper punch plate 11 to move downward and squeeze the spring 171, and make the upper punch 16 pass through the upper punch heating plate 15 and extend into the forming hole 21. At this time, the heated upper punch 16 can press the metal powder filled in the forming hole 21 together with the lower punch 61 and the core rod 51, so that the metal powder wraps the coil body of the inductor coil, and the final inductor product is obtained by hot pressing. Then the upper driving device drives the upper punch plate 11 to move upward respectively, and the spring 171 can drive the upper punch 16 to reset quickly under the elastic action, and then move the upper punch guide plate 12 upward. The lower driving device also drives the core rod 51 to move downward at the same time. Finally, condensed water is connected through each water transport joint 7 and the water transport pipe to cool the molded product, that is, a hot pressing molding operation is completed.

[0042] It should be noted here that the upper and lower driving devices of the powder molding press described in this embodiment are conventional structures of powder molding presses currently on the market. The hot pressing die frame of this embodiment can be used in conjunction with a variety of powder molding presses and can be replaced with any model. This embodiment only involves structural improvements to the hot pressing die frame that is easy to disassemble and assemble.

[0043] In summary, the beneficial effects of the present invention are as follows:

[0044] 1. The present invention sets the core rod module separately from other components of the hot pressing die frame, so that the entire core rod module can be installed and replaced, which is convenient for installation and disassembly, reduces the complexity of operation and the labor intensity of workers, saves installation time, and can be quickly disassembled for repair or replacement when the core rod or the lower punch is worn, thereby reducing the use and maintenance costs. The operation is stable and reliable, and the disassembly and assembly efficiency is greatly improved. It is suitable for a variety of powder forming molds and has a wide range of uses, which can realize large-scale and standardized production of enterprises.
