Description

Technical Field

[0001] The invention relates to the technical field of thermal shaping, in particular to a thermal shaping device for metal injection molding. Background Art

[0002] Sintering is a process in the metal injection molding process. Sintering eliminates the pores between powder particles, making the metal injection molded product fully dense or nearly fully dense. After sintering, the metal usually needs to be heat-shaped.

[0003] For example, a heat shaping device for metal structures used for die-casting, with publication number CN115138715A, is provided with a striking and shaping mechanism that can drive the mounting column to move back and forth up and down, so that the striking hammer and the protective hammer can move back and forth up and down. The cooperation of the limit groove, the limit block and the spring can buffer the striking of the protective hammer to avoid the strong impact force caused by the direct contact of the striking hammer with the metal surface, and to prevent the protective hammer from being able to pop up downward under the elastic force of the spring, so as to form an elastic striking on the metal surface, and the shaping effect is better and more obvious. However, in actual use, during the heat shaping process of the metal component, in order to protect the mold and reduce the friction between the metal component and facilitate subsequent demolding, the shaping mold needs to be sprayed with lubricant regularly. It is not convenient to spray the lubricant on the mold during the shaping process. If the spraying is performed directly during the shaping process, an additional spraying step needs to be added. The spraying time is long, and it is not easy to ensure the continuity of the metal component processing and shaping, and the uniformity of the spraying cannot be guaranteed. It is easy to cause inconsistent spraying thickness and low spraying efficiency, and there are certain defects in use.

[0004] Therefore, we propose a heat shaping device for metal injection molding to solve the above problems. Summary of the Invention

[0029] 1. When heat shaping a metal component, place the component in the lower mold on the rear side above the workbench. The lower mold is arranged on a rotating plate with four circumferences. Then, the rotating motor is started to drive the rotating plate to rotate a quarter turn counterclockwise, so that the placed component is rotated to the bottom of the upper mold. The lower mold on which the component is placed is rotated to the left side above the workbench. The electric push rod drives the heating plate to move above the component to heat the component. After heating, the heating plate is reset, and the hydraulic cylinder drives the movable plate to move down; the upper mold and the lower mold are clamped to shape the component. Then, the upper mold is reset, and the rotating motor is started to drive the rotating plate to rotate a quarter turn, so that the ejector rod contacts the boss, so that the ejector rod moves up and drives the ejector plate to move up to eject the component. At this time, the lower mold on which the component is placed is rotated to the front side above the workbench to facilitate the removal of the component. Then, the rotating motor can be started to drive the rotating plate to continue to rotate a quarter turn. At this time, the lower mold that has just taken out the component is rotated to the right side above the workbench. At this time, the fixed rod moves to the rear opening of the movable groove on the arc plate. The movable groove is tilted, and after the rotating plate is rotated, the movable groove can be used to push the fixed rod to move, so that the fixed rod can move close to the rotating plate, and the movable groove can be used to push the fixed rod to move, so that the movable rod can slide on the fixed plate, and the telescopic spring can be stretched to make the rotating frame move. After the rotating frame moves, it can drive the spraying pipe to move, so that the spraying pipe moves to spray lubricant on the lower mold. The four lower molds can be continuously shaped and sprayed under the rotation of the rotating plate. The four lower molds rotate a quarter of a circle in turn, so that the lower molds at different positions can continuously spray lubricant, place components, shape components and take out components, so that the four lower molds can be automatically sprayed with lubricant one by one during the continuous shaping process of the components, saving spraying time and avoiding waste of lubricant.

[0030] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring or rubber cushion, and castor is arranged on the pin of base bottom four, to carry mobile handler location.

[0031] 3. If the upper mold is sprayed with lubricant, after the shaping work is completed, the movable plate can be reset and then moved up, so that the moving rod enters the sliding grooves on the two mounting plates, and the second pump body is started to spray the lubricant inside the storage barrel through the spray pipe, and then the movable plate is moved up. At this time, the moving rod abuts against the sliding groove, and the sliding groove is tilted. With the upper part of the movable plate, the moving rod can be driven to move up, and the moving rod can move by abutting against the sliding groove, so that the two groups of moving rods on both sides of the movable plate move close to each other, so that the two groups of movable plates on both sides of the movable plate are close to each other, the positioning rod is fixed on the movable plate, and the spray pipe can be driven to move with the movement of the movable plate. The spray pipe drives the movable plate to move during the movement, and the positioning rod will only move up and down with the movable plate. The movable plate is The positioning rod slides on the guide, and the connecting plate is fixed on the two positioning rods, so that the reset spring can be stretched and the rotating rod and the driven gear can rotate. After the driven gear moves, it engages with the rack to rotate the rotating rod, thereby driving the spray pipe to rotate, and the torsion spring can be deformed. After the driven gear moves away from the rack, the rotating rod is reset under the action of the torsion spring, so that the spray pipe is reset. Gaps are provided between the multiple racks, so that the rotating rod can automatically reset after the driven gear moves away from the rack, and then the spray pipe can swing back and forth in the process of driving the spray pipe to move, and the lubricant can be evenly sprayed on the bottom of the upper mold to ensure uniform spraying of the upper mold. When spraying the upper mold, it is only necessary to move the movable plate upward, which is convenient for operation and improves work efficiency and practicality.

[0060] Example 3: Figure 1 and Figures 8-10As shown, if the upper mold 114 is sprayed with lubricant, after the shaping work is completed, the movable plate 112 can be further moved up after it is reset, so that the moving rod 306 enters the sliding groove 307 on the two mounting plates 305, and the second pump body 313 is started to spray the lubricant inside the storage barrel 312 through the spraying pipe 311, and then the movable plate 112 is moved up. At this time, the moving rod 306 is in contact with the sliding groove 307, and the sliding groove 307 is tilted. As the movable plate 112 moves up, the moving rod 306 is in contact with the sliding groove 307, and the sliding groove 307 is tilted. The movable plate 112 is moved by the two groups of movable rods 306 on both sides, and the two groups of movable plates 302 on both sides of the movable plate 112 are moved closer to each other. The positioning rod 301 is fixed on the movable plate 112, and the movement of the movable plate 302 can drive the spraying pipe 311 to move. The spraying pipe 311 drives the movable plate 302 to move during the movement. The positioning rod 301 only moves up and down with the movable plate 112. The movable plate 302 slides on the positioning rod 301 for guidance, and the connecting plate 303 is fixed on the two positioning rods 301, so that the reset spring 304 can be stretched, and the rotating rod 309 and the driven gear 315 can be rotated. After the driven gear 315 moves, it meshes with the rack 317 to rotate the rotating rod 309, thereby driving the spray pipe 311 to rotate and deforming the torsion spring 314. After the driven gear 315 moves away from the rack 317, the rotating rod 309 is reset under the action of the torsion spring 314. The position allows the spray pipe 311 to be reset, and gaps are set between the multiple racks 317, so that the rotating rod 309 can automatically reset after the driven gear 315 moves away from the rack 317, and then the spray pipe 311 can be driven to swing back and forth during the movement, and the lubricant can be evenly sprayed on the bottom of the upper mold 114 to ensure uniform spraying of the upper mold 114. When spraying the upper mold 114, it is only necessary to move the movable plate 112 upwards, which is convenient for operation and improves work efficiency and practicality.

[0061] Working principle: When using the metal injection molding heat shaping device, first, according to Figures 1-10As shown, when the metal component is heat-formed, the component is placed in the lower mold 106 on the rear side above the workbench. Four lower molds 106 are arranged circumferentially on the rotating plate 103. Then the rotating motor 102 is started to drive the rotating plate 103 to rotate a quarter of a turn counterclockwise, so that the placed component is rotated to the bottom of the upper mold 114. The lower mold 106 on which the component is placed is rotated to the left side above the workbench 1. The electric push rod 116 drives the heating plate 117 to move above the component to heat the component. After heating, the heating plate 117 is reset and the hydraulic cylinder is used to press the heating plate 117 to heat the component. 111 drives the movable plate 112 to move downward; the upper mold 114 and the lower mold 106 are molded together to shape the component, and then the upper mold 114 is reset, and the rotary motor 102 is started to drive the rotating plate 103 to rotate a quarter of a circle, so that the ejector 107 contacts the boss 109, so that the ejector 107 moves upward and drives the ejector plate 108 to move upward to eject the component. At this time, the lower mold 106 on which the component is placed is rotated to the front side above the workbench 1, which is convenient for the component to be taken out. Then the rotary motor 102 can be started to drive the rotating plate 103 to continue to rotate a quarter of a circle. After one circle, the lower mold 106 that has just taken out the component rotates to the right side above the workbench 1. At this time, the fixed rod 203 moves to the rear opening of the movable groove 211 on the arc plate 210, and then the rotating plate 103 continues to rotate a quarter of a circle, and the first pump body 209 is started to extract the lubricant inside the barrel body 208, and then the lubricant is sprayed out through the spray pipe 207. The outer bottom of the fixed rod 203 abuts against the movable groove 211, and the movable groove 211 is tilted. After the rotating plate 103 rotates, it can abut against the movable groove 211 and the fixed rod 203. Then, the fixed rod 203 is pushed to move so that the fixed rod 203 can move closer to the rotating plate 103. The fixed rod 203 can be pushed to move through the movable groove 211, so that the movable rod 202 slides on the fixed plate 201, and the telescopic spring 204 can be stretched to move the rotating frame 206. After the rotating frame 206 moves, it can drive the spraying pipe 207 to move, so that the spraying pipe 207 moves to spray lubricant on the lower mold 106. The four lower molds 106 can be continuously shaped and sprayed under the rotation of the rotating plate 103.

[0062] During the movement of the fixed rod 203, the movable frame 215 can be driven by the connecting frame 217 to slide on the support rod 214, so that the movable frame 216 is moved. During the movement of the movable frame 216, the column 222 is driven to slide in the guide groove 221. The movable frame 216 can be driven by the fixed rod 203 to move close to the rotating plate 103. The outer side of the column 222 is always in contact with the inner side of the guide groove 221. When the movable frame 216 drives the column 222 to move, the guide groove 221 is wavy as a whole. The movable frame 216 can move left and right on the movable frame 215, so that during the movement of the movable frame 216, the column 222 is closed by the contact with the guide groove 221, so that the column 222 can be pushed to move back and forth, thereby The reciprocating movement of the movable frame 216 can drive the tooth plate 218 to move back and forth. After the tooth plate 218 moves, it can drive the rotating frame 206 to swing back and forth by meshing with the rotating gear 219, so that the rotating frame 206 can swing back and forth during the movement, and the spray pipe 207 can swing back and forth during the movement. If the upper mold 114 is sprayed with lubricant, after the shaping work is completed, the movable plate 112 can continue to move up after it is reset, so that the movable plate 112 enters the sliding groove 307 on the two mounting plates 305, and the second pump body 313 is started, so that the lubricant inside the storage barrel 312 is sprayed out through the spray pipe 311, and then the movable plate 112 is moved up. At this time, the movable rod 306 and the sliding groove 307 are The two sets of movable plates 302 on both sides of the movable plate 112 are moved closer together, and the positioning rod 301 is fixed on the movable plate 112. The movement of the movable plate 302 can drive the spraying pipe 311 to move. The spraying pipe 311 drives the movable plate 302 to move during the movement. The positioning rod 301 can only move up and down with the movable plate 112. The movable plate 302 slides on the positioning rod 301 for guidance, and the connecting plate 303 is fixed on the two positioning rods 301, so that The reset spring 304 is stretched, and the rotating rod 309 and the driven gear 315 are rotated. After the driven gear 315 moves, it engages with the rack 317 to rotate the rotating rod 309, thereby driving the spray pipe 311 to rotate, and can cause the torsion spring 314 to deform. After the driven gear 315 moves away from the rack 317, the rotating rod 309 is reset under the action of the torsion spring 314, so that the spray pipe 311 is reset. There are gaps between the multiple racks 317, so that the rotating rod 309 can automatically reset after the driven gear 315 moves away from the rack 317, and then the spray pipe 311 can swing back and forth in the process of driving the spray pipe 311 to move, so that the lubricant can be evenly sprayed on the bottom of the upper mold 114.
