Description

Technical Field

[0001] The utility model relates to the technical field of automobile radiator production, in particular to a radiator main plate mold. Background Technique

[0002] The manufacturing processes of radiator main plates mainly include two methods: stamping and casting, but the stamping process dominates in the manufacturing of radiator main plates. The stamping process includes steps such as feeding, lubricating, and stamping. Before welding, the material is lubricated through a lubricating device, and operations such as cutting, tooth cutting and flanging, and punching are carried out through a stamping device, so as to realize the forming of the radiator main plate. This process has the advantages of low investment, low technical threshold, high production efficiency, etc., so it is widely used in the manufacturing process of radiator main plates.

[0003] The technical solution disclosed in the Chinese patent with the authorization announcement number CN210702102U fills a liftable support block inside the stamping die groove to play a supporting role. After that, the sheet metal is pressed tightly by a pressing plate and then stamped and formed, effectively avoiding the problems of bottom bulging and sheet metal side warping, improving the product quality. By jointly forming a pushing structure with a pushing plate, a push rod, and a connecting rod, the linkage of the structure is formed, which is convenient to use. And after the mold is opened, the workpiece is directly lifted up, and the mold taking is convenient.

[0004] However, this device still has deficiencies: This device uses a spring as the power structure, and the service life of the spring is limited. As the use time prolongs, it will gradually become weak, and then the structure reset will no longer be accurate or even fail. And because the radiator main plate is a porous structure, cutting fragments will be generated during stamping. In this device, although the cutting fragments can be separated from the bottom of the support block, the separated fragments are easy to accumulate, which will affect the stroke of the support block.

[0016] Compared with the prior art, the utility model has the following beneficial technical effects:

[0017] By setting the structures of the support base, support plate, movable plate and push block A, during the stamping process, the support plate is preferentially stressed and slides downward, synchronously pushing the movable plate to slide downward. After the aluminum original plate enters the mold cavity, its edge is cut off. Then, the push block B presses down on the push block A to cut off the scrap. After the push block B completely disengages from the aluminum original plate, the movable plate moves upward and resets, driving the support plate to move upward and reset.

[0023] Embodiment 1

[0024] As Figures 1 - 3As shown in the figure, a main plate mold of a radiator proposed by the utility model includes a base 1, a movable plate 4, a tensioning component, and a bracket 8. A mold cavity 101 with an open upper end is arranged in the base 1. A support seat 2 and a support plate 3 are arranged in the mold cavity 101. The support plate 3 is located above the support seat 2 and is slidably connected to the inner wall of the mold cavity 101. A number of through holes 301 are arranged on the support plate 3. The movable plate 4 is arranged in the mold cavity 101 and is located below the support seat 2. A number of pushing blocks A5 are arranged on the movable plate 4. The pushing blocks A5 penetrate through the support seat 2 and are inserted into the through holes 301. A sliding rod A6 is arranged on the movable plate 4, and the sliding rod A6 is connected to the support plate 3. A number of through holes are arranged on the support seat 2, and each pushing block A5 penetrates through the corresponding through hole on the side and is slidably connected to its inner wall. The tensioning component is located in the mold cavity 101. The tensioning component includes two permanent magnets A7. The two permanent magnets A7 are respectively connected to the bottom of the movable plate 4 and the bottom of the mold cavity 101, and the ends with the same magnetic poles of the two permanent magnets A7 face each other. The tensioning component pushes the movable plate 4 towards the support seat 2 in the working state. The bracket 8 is slidably connected to a top plate 9. An upper die base 13 and a number of pushing blocks B10 corresponding to each pushing block A5 are arranged at the bottom of the top plate 9. A driving component for driving the top plate 9 to lift is arranged on the bracket 8. The driving component includes a hydraulic cylinder 81. The cylinder barrel of the hydraulic cylinder 81 is connected to the bracket 8, and the push rod of the hydraulic cylinder 81 is connected to the top plate 9. The upper die base 13 is located below the top plate 9. The top plate 9 is slidably connected to a sliding rod B11. The bottom of the sliding rod B11 is connected to the upper surface of the upper die base 13, and the top of the sliding rod B11 is connected to a protection plate 12. The protection plate 12 is located above the top plate 9. A permanent magnet B15 is arranged on each of the sides of the top plate 9 and the protection plate 12 that are close to each other. The ends with opposite magnetic poles of the two permanent magnets B15 face each other. The suction force of the permanent magnet B15 is used to make it necessary to use greater force to press down the upper die base 13 at the same height of the top plate 9, so as to facilitate flattening the aluminum original plate with the cutting plate 14 on the upper die base 13. A cutting plate 14 adapted to the mold cavity 101 is arranged at the bottom of the upper die base 13, and each pushing block B10 penetrates through the cutting plate 14 and is slidably connected to it.

[0025] In this embodiment, the aluminum sheet is conveyed by unwinding with an aluminum strip roller, and the aluminum strip slides along the upper surface of the base 1 under the drive of the traction mechanism. When the device is started, the hydraulic cylinder 81 presses down the top plate 9, and then the cutting plate 14 preferentially contacts the upper surface of the aluminum original plate and cooperates with the support plate 3 to smooth its surface, and then the cutting plate 14 presses down the aluminum original plate and makes it enter the mold cavity 101, thereby forming a main sheet model in the mold cavity 101, and then the top plate 9 continues to slide down and separates with the permanent magnet B15, and the top plate 9 contacts and squeezes the upper mold seat 13, and the push block B10 punches down the aluminum original plate and presses the punched pieces into the through hole 301. After the punching is completed, the hydraulic cylinder 81 pulls up the top plate 9, and the cutting plate 14 is pressed down. The broken plate 14 is pulled out from the mold cavity 101. At this time, since the support plate 3 is no longer under heavy pressure and the push block A5 is no longer under pressure, the movable plate 4 slides upward and resets under the repulsive force of the permanent magnet A7 at its bottom and the permanent magnet A7 at the bottom of the mold cavity 101. The support plate 3 slides upward and resets synchronously and pushes the main plate out of the mold cavity 101, and the push block A5 pushes the broken pieces that have been punched out upward along the through hole 301 until they are re-embedded in the main plate. The main plate slides horizontally to demold, and when the main plate is separated from the base 1, the broken pieces automatically fall off and separate from the main plate.

[0026] Embodiment 2

[0027] like Figure 1 and Figure 4 As shown, the present invention proposes a heat sink main plate mold. Compared with the first embodiment, the discharging side of the base 1 is connected to a separation discharging mechanism, and the separation discharging mechanism includes a guide frame 16 and multiple groups of conveying components. The guide frame 16 is provided with an inclined slot 161 for separating broken pieces, and two rotating shafts 17 are symmetrically provided on the guide frame 16. Each group of conveying components is connected to the rotating shaft 17, and each conveying component is parallel to each other. The conveying component includes a roller 18 and a conveyor belt 19. The two rollers 18 are coaxially connected to the rotating shaft 17 on the corresponding side, respectively. The rollers 18 on both sides are connected by transmission through the conveyor belt 19, and an annular groove is provided on the arc surface of the roller 18. A ring 181 that rotates with the roller 18 is provided in the annular groove. The rings 181 on both sides are connected to the same connecting rod 20. The width of the connecting rod 20 is the same as that of the conveyor belt 19, and the upper and lower surfaces of the connecting rod 20 are both attached to and slidably connected to the inner arc surface of the conveyor belt 19.

[0028] In this embodiment, the aluminum original plate slides toward the guide rack 16 and drives the stamped main plate and the stamped cut fragments to slide. The main plate and the aluminum original plate are transported by the conveyor belt 19. When the main plate leaves the conveyor belt 19, it automatically falls off, and the fragments fall along the gap between the conveyor belts 19 into the inclined chute 161. Since a connecting rod 20 is added between the rollers 18, the connecting rod 20 closes the inner space of the conveyor belt 19 to prevent the fragments from falling into the inner side of the conveyor belt 19. This structure can realize the rapid separation of the aluminum original plate, the main plate and the fragments, and the separated fragments will not fall on the base.

[0029] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the relevant art.
