Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a positioning structure for a curved surface product forming mold. Background Technology
[0002] A mold is a set of molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, and smelting. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of objects by changing the physical state of the material being molded. By feeding a long strip of sheet material into a mold, stamping can be performed, and multiple finished products can be stamped from a single sheet.
[0003] The existing positioning structure of the forming mold for curved products requires manual positioning of the sheet metal to prevent the long strip sheet metal from shifting back and forth and to avoid defects in the stamped finished product. However, manual positioning is sometimes inaccurate and time-consuming, which affects production efficiency. Utility Model Content

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] Example
[0020] like Figure 1-4As shown, the present invention proposes a positioning structure for a curved product forming mold, including a base 1, which is placed on a horizontal surface. A first support 101 is fixedly connected to the top of the base 1, and a hydraulic rod 102 is fixedly installed in the middle of the first support 101. The first support 101 supports the hydraulic rod 102, and an upper mold 103 is fixedly installed on the output shaft of the hydraulic rod 102. The upper mold 103 is replaceable. When the hydraulic rod 102 is working, the upper mold 103 can move up and down. A lower mold 104 is fixedly installed on the top of the base 1 of the upper mold 103. The lower mold 104 is replaceable. The upper mold 103 and the lower mold 104 cooperate. When the upper mold 103 moves down, it can cooperate with the lower mold 104 to stamp and form the sheet metal.
[0021] A mounting bracket 204 is fixedly connected to the top of the base 1. The mounting brackets 204 are distributed on the front and rear sides. Multiple first rotating cylinders 205 of equal height are installed between the mounting brackets 204. Each mounting bracket 204 contains a drive mechanism that allows multiple first rotating cylinders 205 to rotate simultaneously. When a plate is placed on a first rotating cylinder 205, it can move to the left. A second support 2 is fixedly connected to the top of the base 1. A first electric telescopic rod 201 is fixedly installed in the middle of the second support 2. The second support 2 supports the first electric telescopic rod 201. The output shaft of the first electric telescopic rod 201 is fixedly installed with… The movable frame 202 and the first electric telescopic rod 201 are in operation, which can make the movable frame 202 move up and down. The second rotating cylinder 203 is installed in the middle of the movable frame 202. The movable frame 202 has a drive device inside, which can make the second rotating cylinder 203 rotate. The rotation speed is the same as that of the first rotating cylinder 205 but the opposite direction. The second rotating cylinder 203 cooperates with the leftmost first rotating cylinder 205. As the movable frame 202 moves downward, the second rotating cylinder 203 can clamp plates of different thicknesses with the leftmost first rotating cylinder 205. When the second rotating cylinder 203 can no longer move downward, the first electric telescopic rod 201 stops working.
[0022] A slide structure 3 is fixedly connected to the top of the base 1. Slide grooves are provided on both sides of the interior of the slide structure 3. Slide bars 301 are slidably connected inside the slide structure 3. There are two slide bars 301. A rack 302 is fixedly connected to the side of the slide bar 301. The rack 302 and the slide bar 301 are a whole. When the slide structure 3 moves, a gear 303 is rotatably connected to the middle of the slide structure 3. The rack 302 meshes with the gear 303. When the rack 302 on one side moves back and forth, it will cause the gear 303 to rotate. The rack 302 on the other side also moves back and forth, but in the opposite direction. The slide bars 301 are parallel to each other. The distance from the slide bars 301 to the gear 303 is the same. The slide structure 3 is a closed structure at the front and back. The rack 302 can always mesh with the gear 303 and will not disengage.
[0023] A connecting strip 304 is fixedly connected to the side of the sliding strip 301. The connecting strip 304 moves back and forth with the sliding strip 301. A mounting seat 4 is fixedly connected to the top of the connecting strip 304. The mounting seat 4 moves back and forth with the connecting strip 304. Since the two racks 302 move in opposite directions, the two mounting seats 4 move in opposite directions and can move closer and further away from each other. A third rotating cylinder 401 is rotatably connected to the upper part of the mounting seat 4. The third rotating cylinder 401 moves back and forth with the mounting seat 4. The front third rotating cylinder 401 and the rear third rotating cylinder 401 can move closer and further away from each other. At the same time, the third rotating cylinder 401 can rotate. When the third rotating cylinders 401 move closer to each other, they will contact the plate on the first rotating cylinder 205. The plate on the first rotating cylinder 205 can be moved towards the center for positioning. The movement of the plate will cause the third rotating cylinder 401 to rotate. The resistance of the plate movement is very small. The third rotating cylinder 401 does not contact the first rotating cylinder 205, which can avoid mutual interference.
[0024] A second electric telescopic rod 305 is fixedly installed at the front of the slide structure 3. The extension range of the second electric telescopic rod 305 can be controlled. The output shaft of the second electric telescopic rod 305 is fixedly connected to the front connecting bar 304. When the second electric telescopic rod 305 is working, the front connecting bar 304 can move back and forth, the right sliding bar 301 and rack 302 can move back and forth, the gear 303 can rotate, the left sliding bar 301 and rack 302 can move back and forth, the rear connecting bar 304 can move back and forth, the mounting base 4 can move accordingly, and the third rotating cylinders 401 can move closer and further away from each other. After the third rotating cylinders 401 on both sides come into contact with the plate, the third rotating cylinders 401 can no longer move, and the second electric telescopic rod 305 stops working.
[0025] In this embodiment, the long strip of material is first placed on the first rotating drum 205 and between the second rotating drums 203, with the left side of the material not in contact with the second rotating drum 203. At this time, the material will move to the left, the second electric telescopic rod 305 will operate, the front connecting bar 304 will move backward, the right sliding bar 301 and rack 302 will move backward, the gear 303 will rotate, the left sliding bar 301 and rack 302 will move forward, the rear connecting bar 304 will move forward, and the third rotating drums 401 will move closer to each other, clamping the material from the front and back. When the material moves to the leftmost first rotating drum 205, the first... When the electric telescopic rod 201 is in operation, the second rotating drum 203 moves downward with the moving frame 202, and can clamp the plate from the top and bottom with the leftmost first rotating drum 205. When the unpressed part moves between the upper mold 103 and the lower mold 104, all rotating drums stop rotating, the hydraulic rod 102 is activated, the upper mold 103 moves down to perform stamping and forming, and after the finished product is taken out, the plate continues to move. This equipment can position the long strip plate from the front and back, restricting the long strip plate to the middle position, without the need to manually position the front and back of the long strip plate. The positioning is accurate and saves time and effort.
[0026] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
