[0018] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0019] like Figures 1 to 6 As shown, the present invention provides a ferrite magnetic tile 5 processing forming equipment, including a forming mold, the forming mold includes a bottom mold assembly 1 and an upper mold assembly 3 that are aligned and matched with each other, and the bottom mold assembly 1 and the upper mold assembly 3 are extruded by docking and combining to achieve extrusion molding of the magnetic tile material. A docking assembly 2 is provided between the bottom mold assembly 1 and the upper mold assembly 3. Figure 2 The docking component 2 includes a docking frame 201, and a plurality of docking grooves 202 are arranged inside the docking frame 201. The docking grooves 202 of the docking component 2 are used to accommodate the material, so that the extrusion molding process occurs inside the docking frame 201. Compared with the traditional extrusion molding mold, the extrusion molding process occurs inside the mold with a large dead weight and complex geometric structure. The present application sets up the docking component 2 independently, making it easier to disassemble, repair and clean it.

[0020] An air supply separation slot 203 is provided in the middle of each of the docking slots 202. A constant-pressure air supply unit is provided in the middle of the docking frame 201. The constant-pressure air supply unit is connected to the air supply separation slots 203 and is used to supply high-pressure air to the air supply separation slots 203. This allows for the initial separation of the formed magnetic tiles within the docking slots 202, thereby reducing contact between the mechanical structure of the device and the magnetic tiles during complete demolding, thereby reducing the generation of cracks. In one embodiment, the bottom mold assembly 1 includes a frame 101, and a lifting hydraulic cylinder 102 is fixedly installed on the inner wall of the frame 101. The output end of the lifting hydraulic cylinder 102 is fixedly connected to the bottom mold plate 103, and the top of the bottom mold plate 103 is fixedly connected to a plurality of bottom mold rods 104; the plurality of bottom mold rods 104 are respectively slidably arranged inside a plurality of docking grooves 202; the bottom mold plate 103 is driven to move up and down by the lifting hydraulic cylinder 102, and then the various bottom mold rods 104 are synchronously driven to move up and down to meet the needs of forming and pressing the magnetic tiles; in order to make the pushing pressure of the bottom mold rods 104 at various locations on the bottom mold plate 103 more balanced, a pushing rack 106 is fixedly connected to the bottom of the bottom mold plate 103, and both sides of the pushing rack 106 are inclined.

[0021] In one embodiment, see Figure 1 and Figure 2 The upper mold assembly 3 includes an upper mold plate 301, and a plurality of upper mold rods 302 are fixedly connected to the bottom of the upper mold plate 301. The bottoms of the plurality of upper mold plates 301 are arranged corresponding to the tops of the plurality of docking grooves 202. An external hydraulic drive mechanism is arranged above the upper mold plate 301, and the upper mold plate 301 is driven up and down by the hydraulic drive mechanism. The size of the upper mold rod 302 is consistent with the size of the inner cavity of the docking groove 202, so as to achieve stable extrusion and closure of the material, and at the same time, achieve obstruction and closure of the air supply separation groove 203 during the extrusion process, so that the pressure can be stably accumulated in the docking cover 204.

[0022] In one embodiment, see Figure 4 The top of the bottom mold rod 104 is fixedly connected with a pushing block 105, and the top of the pushing block 105 protrudes upward and is set as an arc-shaped surface. The bottoms of several upper mold rods 302 are all recessed upward and set as concave grooves. The magnetic tiles are pressed and formed by the cooperation of the concave grooves and the arc-shaped surfaces. The air supply separation groove 203 is set as an arc-shaped groove, and the curvature of the arc-shaped groove is consistent with the curvature of the arc-shaped surface, so that the air flow sent out along the air supply separation groove 203 can better fit the shape of the contact surface between the top surface of the pushing block 105 and the magnetic tile, thereby improving the blowing separation efficiency and reducing the damage to the corners of the magnetic tile caused by the air flow.

[0023] In one embodiment, see Figure 2 and Figure 5Specifically, the constant pressure air supply unit includes an air guide frame 209, the inner wall of which is fixedly connected to a plurality of connecting pipes 208, the middle of which is fixedly connected to a plurality of diversion pipes 206, one end of which is fixedly connected to a docking cover 204, which is respectively fixedly connected to one side of a plurality of air supply separation slots 203, an air pressure sensor 207 is fixedly installed in the middle of each of the diversion pipes 206, and one side of the air guide frame 209 is fixedly connected to an air intake pipe 210. One end of the air inlet pipe 210 is fixedly connected to the output end of the external air pump, and the air flow is delivered to each docking cover 204 through the air inlet pipe 210 and the diversion pipe 206 and other structures. The air pressure sensor 207 is used to detect the air pressure in the docking cover 204 so that it can meet the requirements. When the formed magnetic tiles pass through the air supply separation groove 203, the air flow in the docking cover 204 can overcome the material pressure in the docking groove 202 and be stably delivered into the docking groove 202, thereby realizing the stable separation of the formed magnetic tile material and structural plates such as the pushing block 105 and the upper mold rod 302.

[0024] In one embodiment, see Figure 4 In order to further reduce the damage of the magnetic tile during the demolding process, a drainage cavity 1051 is opened inside the pushing block 105, and a plurality of diversion cavities 1052 are fixedly connected to the edge of the drainage cavity 1051. A drainage tube is fixedly connected to the middle of the drainage cavity 1051, and one end of the drainage tube is fixedly connected to the output end of the external solvent pump. The release agent is applied to the inner wall of the docking groove 202 by using the drainage tube and the diversion cavity 1052 and other structures to reduce the adhesion of the magnetic tile to the inner wall of the docking groove 202 and other structures.

[0025] In one embodiment, in order to improve the sealing between the pushing block 105 and the docking groove 202 , a sealing gasket 1053 is fixedly connected to the edge of the pushing block 105 , and a through groove corresponding to the diversion cavity 1052 is opened in the middle of the sealing gasket 1053 .

[0026] In one embodiment, see Figure 6 In order to achieve the synchronous removal of the magnetic tiles after the forming is completed, a material unloading mechanism 4 for unloading the formed magnetic tiles is provided on one side of the forming mold. The material unloading mechanism 4 includes a mounting frame 401, and a transverse guide rail 402 is fixedly installed on the inner wall of the mounting frame 401. A material unloading frame 403 is slidably installed on the inner wall of the transverse guide rail 402. Several material picking push rods are fixedly installed inside the material unloading frame 403, and the bottoms of the several material picking push rods are fixedly connected to material picking suction cups 404. The material unloading is carried out by using the material picking suction cups 404 and a negative pressure suction method, which reduces the damage to the magnetic tiles themselves.

[0027] When the present invention is in use, first, the external feeding device adds the material into the docking groove 202; the external hydraulic drive mechanism drives the upper mold assembly 3 to move downward, so that the upper mold rod 302 penetrates the docking groove 202 to squeeze the material. At this time, the jacking hydraulic cylinder 102 in the bottom mold assembly 1 is synchronously started, driving each bottom mold rod 104 and the pushing block 105 to move upward, and the material in the docking groove 202 is squeezed and formed by the squeezing of the pushing block 105 and the upper mold rod 302. The state at this time is shown in FIG. Figure 3 (a); After forming, the lifting hydraulic cylinder 102 is started again, driving the pushing block 105 and the material to move upward, and the upper mold assembly 3 is driven upward synchronously by the external hydraulic drive mechanism, and the formed material is driven upward while maintaining the extrusion of the material. When the contact position between the top of the material and the arc surface of the upper mold rod 302 is aligned with the air supply separation groove 203, the air flow in the docking cover 204 is sent out by the air supply separation groove 203, and the contact position is blown to achieve separation of the top surface of the material, and then the material continues to move upward. When the contact position between the bottom of the material and the top of the pushing block 105 is aligned with the air supply separation groove 203, the air flow in the docking cover 204 is sent out by the air supply separation groove 203 again, and the contact position is blown to achieve separation of the material from the ground. Figure 3 (b); Then the upper die assembly 3 is synchronously moved upward by the external hydraulic drive mechanism until it is completely separated from the docking frame 201 and continues to be raised. The jacking hydraulic cylinder 102 continues to drive the push block 105 and the material to move upward until the material is discharged from the docking groove 202. Figure 3 (c), at this time, the transverse guide rail 402 of the unloading mechanism 4 is started, driving the unloading rack 403 to move to the top of the docking component 2, and the formed magnetic tile is adsorbed and taken out by the material picking push rod and the material picking suction cup 404, completing the molding operation of the magnetic tile; after the unloading is completed, the jacking hydraulic cylinder 102 continues to drive the pushing block 105 to move down and reset. During the downward movement, it is started by the external solvent pump, and the release agent is transported into the drainage chamber 1051 and the diversion chamber 1052 through the liquid drainage tube, and then sent out from the through groove on the sealing gasket 1053, and the release agent is coated on the inner wall of the docking groove 202, so as to facilitate the subsequent demolding operation of the extruded magnetic tile.
