[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-5 This utility model provides a technical solution:
[0028] Example 1:
[0029] A pre-pressing molding device based on hard magnetic oxide material includes a support leg 1, a hot pressing structure is installed on the top of the support leg 1, loading and unloading structures are installed on the top and left and right ends of the hot pressing structure, and a cooling structure is provided on the bottom left side of the hot pressing structure.
[0030] The hot pressing structure includes a hot pressing unit and a lifting unit. The hot pressing unit is located on top of the lifting unit. The lifting unit includes a worktable 101, with a mounting frame 102 installed in the center of the bottom surface of the worktable 101. A hydraulic cylinder 103 is installed on the top surface of the mounting frame 102, and a lifting plate 104 is installed at the output end of the hydraulic cylinder 103. The hot pressing unit includes a processing frame 105, with a hydraulic cylinder 106 installed in the center of the top surface of the processing frame 105. An upper mold 107 is installed at the output end of the hydraulic cylinder 106, and a heating tube 108 is installed inside the upper mold 107.
[0031] The bottom end of the processing frame 105 is fixedly connected to the top surface of the workbench 101 near the back end. The bottom surface of the workbench 101 is fixedly connected to the top end of the support leg 1. The outer surface of the lifting plate 104 is slidably connected to the inner wall of the lifting hole in the middle of the top surface of the workbench 101. The outer surface of the upper mold 107 is slidably connected to the inner wall of the hot pressing groove in the middle of the top surface of the workbench 101.
[0032] By setting up a hot pressing processing structure, the hydraulic cylinder 103 drives the lifting plate 104 to lift, which facilitates the lifting and discharge of the hot-pressed material. In addition, the heating tube installed inside the upper mold 107 can make the material heat more evenly during hot pressing, resulting in a better hot pressing effect.
[0033] When hot pressing magnetic oxide materials, the material to be processed is conveyed into the forming groove in the middle of the top surface of the worktable 101 through the loading and unloading structure. Then, the hydraulic cylinder 106 is activated to drive the upper mold 107 to press down. At the same time, the heating tube 108 is used to preheat the upper mold 107, thereby effectively ensuring the material is heated and improving the efficiency of hot pressing during the hot pressing process. After hot pressing, the hydraulic cylinder 103 is activated to drive the lifting plate 104 to rise, thereby ejecting the formed material through the forming groove, which facilitates the discharge of the material using the loading and unloading structure.
[0034] Example 2:
[0035] Based on Embodiment 1, the loading and unloading structure includes a loading rack 201. An electric push rod 202 is installed in the middle of the right side of the loading rack 201. A push plate 203 is installed at the output end of the electric push rod 202. A second heating tube 204 is arranged on the left side of the loading rack 201, and a guide plate 205 is arranged on the left side of the second heating tube 204. The left end of the loading rack 201 is fixedly connected to the middle of the right side of the workbench 101. The bottom surface of the push plate 203 is slidably connected to the middle of the top surface of the loading rack 201. The second heating tube 204 is installed in the middle of the top surface of the workbench 101 near the left and right ends of the installation groove. The guide plate 205 is installed in the middle of the left side of the workbench 101.
[0036] The cooling structure includes a loading platform 301. A semiconductor cooler 302 is installed in the middle of the left side of the loading platform 301. A cooling plate 303 is fixedly installed inside the left side of the loading platform 301. An air pump 304 is installed in the middle of the front side of the loading platform 301 near the bottom. A guide tube 305 is installed in the middle of the back side of the loading platform 301. A filter plate 306 is installed in the middle of the right side of the loading platform 301. The output end of the air pump 304 is connected to the inner wall of a circular hole in the middle of the front side of the loading platform 301 near the bottom. The filter plate 306 is snapped onto the right side of the loading platform 301 by a limiting strip. The bottom end of the outer surface of the guide tube 305 is fixedly connected to the inside of a rectangular hole in the middle of the back side of the loading platform 301.
[0037] By setting up the loading and unloading structure and the cooling structure, the electric push rod 202 drives the push plate 203 to move, which facilitates the loading and unloading of the materials to be processed and the materials after hot pressing. The installation of the heating tube 204 facilitates the preheating of the materials to be processed, thereby improving the efficiency of hot pressing. The semiconductor cooler 302 cools the inside of the material carrier 301 through the cooling plate 303, and the air pump 304 and the guide tube 305 blow air to quickly cool the hot-pressed materials.
[0038] By activating the electric push rod 202 to move the push plate 203, the material to be processed and the material to be formed can be loaded and unloaded. The heating tube 204 installed in the mounting groove in the middle of the top surface of the worktable 101 can heat the middle of the top surface of the worktable 101, thereby preheating and keeping the material to be processed, thus effectively ensuring the effect of hot pressing. After forming, the material is unloaded by the installation of the guide plate 205 and placed in the middle of the top surface of the carrier platform 301. Then, the semiconductor cooler 302 is activated to cool, and the cooling energy is transferred to the inside of the carrier platform 301 by the cooling plate 303. At the same time, the air pump 304 is activated to blow air into the inside of the carrier platform 301, and the cooling energy is blown to the formed product in the middle of the top surface of the carrier platform 301 through the guide tube 305. During the blowing process, the filter plate 306 can filter the air entering the inside of the carrier platform 301, thereby effectively preventing dust from entering.
