Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a mold blank positioning mechanism for mold blank processing. Background Technology

[0002] The mold blank is the skeleton of the mold, used to support and fix the core parts of the mold such as the cavity, core, and guiding mechanism, ensuring the precise and stable opening and closing movement of the mold. The quality of the mold blank processing directly affects the assembly accuracy, service life and stability of the molded product.

[0003] The welding of existing mold blanks usually involves the repair of specific parts or the splicing of structures. During the operation, mechanical movement can easily affect the displacement of the workpiece, causing the mold blank plate to be repeatedly adjusted by the welding operator, which reduces the work efficiency of mold blank processing.

[0004] To address this issue, a mold blank positioning mechanism for mold blank processing is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a mold blank positioning mechanism for mold blank processing. It aims to improve the existing technology where mold blank welding usually involves the repair of specific parts or structural splicing. During the operation, mechanical movement can easily affect the displacement of the workpiece, causing the mold blank plate to be repeatedly adjusted by the welding operator, which reduces the working efficiency of mold blank processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mold blank positioning mechanism for processing mold blanks includes a mold welding machine. A processing table is fixedly connected to the top of the mold welding machine. A mold blank body is movably connected to the top of the processing table. An installation mechanism is fixedly connected to the front end of the processing table. The installation mechanism includes a fixed box, connecting rods, and an L-shaped pressure plate. The fixed box is fixedly connected to the front end of the processing table. Connecting rods are movably connected to the left and right sides of the top of the fixed box. An L-shaped pressure plate is fixedly connected to the top of the connecting rods. The end of the L-shaped pressure plate away from the connecting rods contacts the top of the mold blank body. A driving mechanism is fixedly connected to the bottom of the inner wall of the fixed box.

[0008] The above technical solution involves placing the workpiece on the surface of the processing table, then operating the mechanical parts inside the fixed box to move, thereby causing the connecting rod to move downwards under force. The downward movement of the connecting rod drives the L-shaped pressure plate to move synchronously, and the downward movement of the L-shaped pressure plate presses and positions the workpiece on both sides. Then, the mold welding machine is started to work, so that the workpiece is not affected by welding during the mechanical movement and does not shift.

[0009] As a further description of the above technical solution: the driving mechanism includes a U-shaped seat, a double-headed cylinder, a movable rod, and a cross plate. The U-shaped seat is fixedly connected to the bottom of the inner wall of the fixed box. The double-headed cylinder is fixedly connected to the center of the top of the U-shaped seat. The movable rod is movably connected to the left and right sides of the double-headed cylinder through bearings. The bottom of the movable rod is slidably connected to the bottom of the U-shaped seat. The end of the movable rod away from the U-shaped seat is movably connected to the cross plate through a rotating shaft. The left and right sides of the cross plate are fixedly connected to a balancing mechanism.

[0010] Through the above technical solution, the drive mechanism enables the double-headed cylinders to work and push the movable rod to move. While the movable rod moves along the surface of the U-shaped seat, it rotates and folds around the bearing. During the rotation and folding process, the movable rod pulls the cross plate to move synchronously, thereby realizing the transmission of mechanical power.

[0011] As a further description of the above technical solution: the balancing mechanism includes a docking plate, a sliding plate, and a vertical rod. The docking plate is fixedly connected to both the left and right sides of the horizontal plate. The bottom of the connecting rod extends through the interior of the fixed box and is fixedly connected to the top of the docking plate. The sliding plate is fixedly connected to the left side of the docking plate. The vertical rod is fixedly connected to both the left and right sides of the bottom of the inner wall of the fixed box. The top of the vertical rod extends through the top of the sliding plate and is fixedly connected to the top of the inner wall of the fixed box.

[0012] Through the above technical solution, the setting of the balancing mechanism enables the horizontal plate to drive the docking plate to move along during the movement. When the docking plate moves, it drives the connecting rod and the sliding plate to move synchronously. The sliding plate moves vertically along the surface of the vertical rod, thereby stabilizing the downward movement of the connecting rod. Finally, the connecting rod drives the L-shaped pressure plate to move steadily downward to press and position the workpiece.

[0013] As a further description of the above technical solution: the top left and right sides of the U-shaped seat, corresponding to the position of the movable rod, are provided with sliding grooves, which are used in conjunction with the movable rod.

[0014] Through the above technical solution, the sliding groove allows the movable rod to move left and right inside the groove, while also serving as a limit, preventing the movable rod from deviating during movement.

[0015] As a further description of the above technical solution: a damping spring is sleeved on the surface of the vertical rod, and the top and bottom of the damping spring are fixedly connected to the bottom of the slide plate and the surface of the vertical rod, respectively.

[0016] Through the above technical solution, the damping spring can assist the skateboard in its operation and also play a buffering role, preventing the skateboard from moving too fast on the surface of the vertical bar and causing impact that could deform or break the vertical bar.

[0017] As a further description of the above technical solution: a protective shell is fixedly connected to the top of the U-shaped seat and covering the surface of the double-headed cylinder, and the protective shell is used in conjunction with the double-headed cylinder.

[0018] Through the above technical solution, the protective shell can assist the double-headed cylinder in its operation and also play a protective role, preventing the double-headed cylinder from being exposed to the air for a long time and being covered by dust and impurities, which would affect its service life.

[0019] As a further description of the above technical solution: the left and right sides of the U-shaped seat are both fixedly connected with reinforcing ribs, and the number of reinforcing ribs is several and they are evenly distributed.

[0020] The above technical solution, with its reinforcing ribs, assists the U-shaped seat in its operation and also provides reinforcement, preventing deformation and breakage during load-bearing.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up a fixed box, connecting rod and L-shaped pressure plate, the mold blank body can be placed on the surface of the processing table. Then, the mechanical parts inside the fixed box are operated to retract the connecting rod into the fixed box. The connecting rod moves downward and drives the L-shaped pressure plate to move accordingly. The L-shaped pressure plate moves downward and presses and positions the two sides of the mold blank body. Finally, the mold welding machine is started to work, so that the mold blank body is not affected by displacement during the welding mechanical movement, thus achieving the function of positioning and processing the mold blank body.

[0023] 2. In this utility model, the U-shaped seat, double-headed cylinder, and movable rod enable the double-headed cylinder to drive the movable rods on both sides to move synchronously. The movable rods move horizontally along the surface of the U-shaped seat and rotate and fold around the pivot. During the folding process, the movable rods pull the horizontal plate downwards, thereby transmitting mechanical power. Finally, the connecting rod and L-shaped pressure plate follow the movement to press and fix the mold blank body on the processing table, thereby positioning the workpiece and facilitating its processing by the mold welding machine.

[0030] 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.

[0031] Reference Figure 1-4 This utility model provides an embodiment of a mold blank positioning mechanism for mold blank processing, including a mold welding machine 1. A processing table 2 is fixedly connected to the top of the mold welding machine 1. A mold blank body 3 is movably connected to the top of the processing table 2. An installation mechanism 4 is fixedly connected to the front end of the processing table 2. The installation mechanism 4 includes a fixing box 41, connecting rods 42, and an L-shaped pressure plate 43. The fixing box 41 is fixedly connected to the front end of the processing table 2. Connecting rods 42 are movably connected to the left and right sides of the top of the fixing box 41. An L-shaped pressure plate 43 is fixedly connected to the top of the connecting rods 42. 3. The end of the L-shaped pressure plate 43 away from the connecting rod 42 contacts the top of the mold body 3. The bottom of the inner wall of the fixed box 41 is fixedly connected to the drive mechanism 5. By placing the workpiece on the surface of the processing table 2, and then operating the mechanical parts inside the fixed box 41, the connecting rod 42 is forced to move downward. The downward movement of the connecting rod 42 drives the L-shaped pressure plate 43 to move synchronously. The downward movement of the L-shaped pressure plate 43 presses and positions the workpiece on both sides. Then the mold welding machine 1 is started to work, so that the workpiece is not affected by welding and is displaced during the mechanical movement.

[0032] Reference Figure 1-4The drive mechanism 5 includes a U-shaped base 51, a double-headed cylinder 52, a movable rod 53, and a horizontal plate 54. The U-shaped base 51 is fixedly connected to the bottom of the inner wall of the fixed box 41. The double-headed cylinder 52 is fixedly connected to the center of the top of the U-shaped base 51. Movable rods 53 are movably connected to the left and right sides of the double-headed cylinder 52 via bearings. The bottom of the movable rod 53 is slidably connected to the bottom of the U-shaped base 51. The end of the movable rod 53 away from the U-shaped base 51 is movably connected to the horizontal plate 54 via a rotating shaft. Balancing mechanisms 6 are fixedly connected to the left and right sides of the horizontal plate 54. Through the drive mechanism 5, the double-headed cylinder 52 can work to push the movable rod 53 to move. While moving along the surface of the U-shaped base 51, the movable rod 53 rotates and folds around the bearing. During the rotation and folding process, the movable rod 53 pulls the horizontal plate 54 to move synchronously, thereby realizing the transmission of mechanical power and balancing the machine. The structure 6 includes a docking plate 61, a sliding plate 62, and a vertical rod 63. The docking plate 61 is fixedly connected to the left and right sides of the horizontal plate 54. The bottom of the connecting rod 42 passes through the interior of the fixed box 41 and is fixedly connected to the top of the docking plate 61. The sliding plate 62 is fixedly connected to the left side of the docking plate 61. The vertical rod 63 is fixedly connected to the left and right sides of the bottom of the inner wall of the fixed box 41. The top of the vertical rod 63 passes through the top of the sliding plate 62 and is fixedly connected to the top of the inner wall of the fixed box 41. Through the setting of the balancing mechanism 6, the horizontal plate 54 can drive the docking plate 61 to move along with it during the movement. When the docking plate 61 moves, it drives the connecting rod 42 and the sliding plate 62 to move synchronously. The sliding plate 62 moves vertically along the surface of the vertical rod 63, thereby stabilizing the downward movement of the connecting rod 42. Finally, the connecting rod 42 drives the L-shaped pressure plate 43 to move downward and press and position the workpiece.

[0033] Reference Figure 1-4On the top left and right sides of the U-shaped base 51, corresponding to the positions of the movable rod 53, there are sliding grooves 7. The sliding grooves 7 work in conjunction with the movable rod 53. The sliding grooves 7 allow the movable rod 53 to move left and right within the sliding grooves 7, and also serve as limiters to prevent the movable rod 53 from deviating during movement. A damping spring 8 is sleeved on the surface of the vertical rod 63. The top and bottom of the damping spring 8 are fixedly connected to the bottom of the slide plate 62 and the surface of the vertical rod 63, respectively. The damping spring 8 assists the slide plate 62 in its operation and also serves as a buffer to prevent the slide plate 62 from moving too fast on the surface of the vertical rod 63 and causing impact that could deform the vertical rod 63. To prevent deformation and breakage, a protective shell 9 is fixedly connected to the top of the U-shaped seat 51 and the surface of the double-headed cylinder 52. The protective shell 9 works in conjunction with the double-headed cylinder 52. The protective shell 9 assists the double-headed cylinder 52 in its operation and also provides protection, preventing the double-headed cylinder 52 from being exposed to the air for a long time and being covered by dust and impurities, which would affect its service life. Reinforcing ribs 10 are fixedly connected to the left and right sides of the U-shaped seat 51. There are several reinforcing ribs 10, which are evenly distributed. The reinforcing ribs 10 assist the U-shaped seat 51 in its operation and also provide reinforcement, preventing the U-shaped seat 51 from deforming and breaking during the load-bearing process.

[0034] Working principle: The mold blank body 3 is placed on the surface of the processing table 2, and then the double-headed cylinder 52 inside the fixed box 41 is activated. The double-headed cylinder 52 pushes the movable rod 53 to move. The movable rod 53 moves horizontally on the surface of the U-shaped seat 51 in conjunction with the sliding groove 7. During the movement, the movable rod 53 rotates and folds around the bearing. During the folding process, the movable rod 53 pulls the horizontal plate 54 downward. The downward movement of the horizontal plate 54 drives the docking plate 61 to move accordingly. The downward movement of the docking plate 61 drives the connecting rod 42 and the sliding plate 62 to move synchronously. The sliding plate 62 moves vertically along the surface of the vertical rod 63 and compresses the damping spring 8 on the surface of the vertical rod 63. Finally, the connecting rod 42 moves downward, driving the L-shaped pressure plate 43 to move accordingly. The downward movement of the L-shaped pressure plate 43 presses and positions the two sides of the mold blank body 3. Finally, the mold welding machine 1 is started to work normally. During the mechanical movement, the mold blank body 3 is restricted by the L-shaped pressure plate 43 and cannot move, making the processing more stable and efficient.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
