Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold production positioning technology, and in particular to a displacement positioning device for mold production. Background Technology
[0002] Used for forming metal materials, such as die casting molds and stamping molds. Die casting molds are mainly used to inject liquid metal into the mold cavity under high pressure, and after cooling and solidification, they form the required metal parts. They are often used in the production of metal parts in the automotive and electronics industries. Stamping molds, on the other hand, apply pressure to metal sheets through stamping equipment to make them plastically deform, thereby obtaining stamped parts of various shapes, such as automotive body panels and hardware products.
[0003] The currently published patent, CN220944902U, discloses a displacement positioning device for mold production. Due to the arrangement of the rotating gear shaft, drive rack, rack connecting plate, and slide rail, the movable brackets of the two second limit column bases move relative to each other along the slide rail direction, thereby enabling the centering positioning limit rod to clamp the mold towards the center and finally achieve the centering positioning target of the mold. This solves the problem of the inconvenience of centering and aligning the mold in existing displacement positioning devices for mold production, which causes time-consuming and labor-intensive mold processing and fixing.
[0004] Based on the above search findings, when this displacement positioning device is in use, the rotating gear shaft, drive rack, rack connecting plate, and slide rail cause the two second limit column base movable brackets to move relative to each other along the slide rail direction, thereby aligning and clamping the mold towards the center with the center positioning limit rod. However, the mold is positioned and fixed by the meshing action of the gear and rack. Since the mold needs to be subjected to a large pressure during use, it is prone to shaking when subjected to pressure. When the mold shakes, it can drive the rack to move and apply pressure to the gear. Because the teeth used for meshing between the rack and gear are small and the pressure is small, the teeth used for meshing between the rack and gear are prone to damage after long-term use, which affects the stability of the mold fixation, resulting in not only economic losses but also affecting the normal use of the mold. Utility Model Content
[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a displacement positioning device for mold production. This device can solve the problem that the teeth used for meshing between the rack and gear are small in size and have low pressure, so the teeth used for meshing between the rack and gear are easily damaged after long-term use, which affects the stability of the mold fixation, resulting in not only economic losses, but also affecting the normal use of the mold.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a displacement positioning device for mold production, comprising a mounting base and a mold center positioning device; the top of the mounting base has two sliding grooves, and two sliders are slidably connected inside each of the two sliding grooves; the mold center positioning device includes a movable push block, a hydraulic press, two rotating shafts, two rotating support rods, two connecting bridge plates, and two rotating rollers; the movable push block is slidably connected inside the mounting base; the hydraulic press is fixedly installed at the rear end of the mounting base; the output end of the hydraulic press is fixedly installed on the rear side of the movable push block; grooves are provided at both ends of the movable push block; the two rotating shafts are rotatably connected inside the two grooves respectively; and the two rotating support rods are rotatably connected to the surfaces of the two rotating shafts respectively.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a displacement positioning device for mold production, including a mounting base 1 and a mold center positioning device. The top of the mounting base 1 has two sliding grooves 2, and two sliders 3 are slidably connected inside each of the two sliding grooves 2. Guide rods 4 are slidably sleeved inside the two front sliders 3 and the two rear sliders 3, respectively. The two guide rods 4 are fixedly connected inside the two sliding grooves 2. Two movable base rods 5 are fixedly connected to the top of the four sliders 3. Two limiting pins 6 are fixedly connected to the top of each of the two movable base rods 5.
[0026] The mold center positioning device includes a movable push block 7, a hydraulic press 8, two rotating shafts 10, two rotating support rods 11, two connecting bridge plates 12, and two rotating rollers 14. The movable push block 7 is slidably connected inside the mounting base 1. The hydraulic press 8 is fixedly installed at the rear end of the mounting base 1, and the output end of the hydraulic press 8 is fixedly installed on the rear side of the movable push block 7. Grooves 9 are provided at both ends of the movable push block 7. The two rotating shafts 10 are rotatably connected inside the two grooves 9, respectively. The two rotating support rods 11 are rotatably connected to the surfaces of the two rotating shafts 10, respectively. The two connecting bridge plates 12 are slidably connected to the bottom of the two left sliders 3 and the two right sliders 3, respectively. Both connecting bridge plates 12 are slidably installed inside the mounting base 1. Through grooves 13 are provided on the surfaces of the two connecting bridge plates 12, respectively. The two rotating rollers 14 are rotatably connected inside the two through grooves 13, respectively. The ends of the two rotating support rods 11 away from the movable push block 7 are rotatably connected to the surfaces of the two rotating rollers 14, respectively.
[0027] When the mold needs to be centered and its position adjusted, the operator can start the hydraulic press 8. The output end of the hydraulic press 8 slides backward, driving the moving push block 7 to slide backward. The moving push block 7 slides backward and drives the two rotating support rods 11 to rotate through the two rotating shafts 10. The rotation of the two rotating support rods 11 drives the two rotating rollers 14 to slide relative to each other. The sliding of the two rotating rollers 14 drives the two connecting bridge plates 12 to slide relative to each other. The relative movement of the two connecting bridge plates 12 drives the two left sliders 3 and the two right sliders 3 to slide relative to each other. The sliders 3 slide on the surface of the guide slide rods 4. At this time, the four sliders 3 can be guided and positioned by the two guide slide rods 4, ensuring that the four sliders 3 slide horizontally left and right. Sliding block 3 causes the two movable base rods 5 to slide relative to each other. The sliding of the two movable base rods 5 causes the two left and two right limit pins 6 to slide relative to each other to the position where the mold needs to be positioned. At this time, the four limit pins 6 can be inserted into the positioning holes of the mold for fixation, and the bottom of the mold is supported by the two movable base rods 5 to ensure the stability of the mold positioning by the four limit pins 6. At this time, the mold is positioned and fixed by the two rotating support rods 11. The two rotating support rods 11 have a greater pressure resistance, and when the mold is under pressure and shakes, it will not be damaged by the two rotating support rods 11, thus ensuring the stability of the mold fixation. This not only avoids economic losses, but also ensures the normal use of the mold.
[0028] The top wall of the mounting base 1 has a limiting slot 15, and the top of the movable push block 7 is fixedly connected to a limiting block 16, which is slidably connected inside the limiting slot 15.
[0029] When the movable push block 7 slides, it can drive the limit block 16 to slide inside the limit slot 15. At this time, the limit slot 15 can guide and position the limit block 16 and the movable push block 7, ensuring the stability of the movable push block 7 sliding back and forth and preventing the movable push block 7 from tilting when it slides.
[0030] Structural Description:
[0031] Mounting base 1: The basic support component of the entire displacement positioning equipment, providing a platform for the installation and placement of other components. The mold center positioning device and structures with sliders, etc., are all mounted on it;
[0032] Slide 2: A groove-shaped structure formed on the top of the mounting base 1, which provides a track for the sliding of the slider 3, allowing the slider 3 to move horizontally inside it. There are two of them, one for mounting the relevant slider and the other for mounting the guide rod and other components.
[0033] Slider 3: Four sliders 3 are slidably connected inside the two slide grooves 2 respectively. Their tops are connected to the movable base rods 5, which can slide along the guide slide rods 4 inside the slide grooves 2, playing the role of transmitting motion and supporting the upper structure (movable base rods 5 and limit pins 6, etc.). The guide slide rods 4 are slidably sleeved inside the two front sliders and the two rear sliders 3.
[0034] Guide slide rod 4: Two guide slide rods 4 are fixedly connected inside the two slide grooves 2 respectively, and pass through the inside of the four sliders 3, providing guidance for the sliding of the sliders 3, ensuring that the sliders 3 slide horizontally left and right, and restricting their displacement in other directions;
[0035] Movable base rod 5: Two movable base rods 5 are fixedly connected to the top of the four sliders 3 respectively. They move as the sliders 3 slide, and are used to support and connect the limit pin 6. They also support the bottom of the mold when the mold is positioned.
[0036] Limiting pins 6: Four limiting pins 6 are fixedly connected to the top of the two movable base rods 5 respectively. When the slider 3 drives the movable base rods 5 to move to the position where the mold needs to be positioned, the limiting pins 6 can be inserted into the positioning hole of the mold to fix the mold and ensure the stability of the mold positioning.
[0037] The movable push block 7 is slidably connected inside the mounting base 1 and can slide back and forth under the drive of the hydraulic press 8. The grooves 9 at its left and right ends are used to connect the rotating shaft 10, thereby driving the rotating support rod 11 and other components to move, thus realizing the drive of the slider and other structures.
[0038] Hydraulic press 8: Fixedly installed at the rear end of the mounting base 1, it is the power source of the equipment. Its output end is connected to the movable push block 7. Through the extension and retraction of the output end, the movable push block 7 is driven to slide backward or forward, thereby driving the movement of the entire mold center positioning device.
[0039] Grooves 9: These are formed at the left and right ends of the movable push block 7 and are used to install the rotating shaft 10, so that the rotating shaft 10 can rotate within the grooves 9, providing a connection point for the rotation of the rotating support rod 11.
[0040] Rotating shaft 10: Two rotating shafts 10 are respectively rotatably connected to the grooves 9 at the left and right ends of the movable push block 7, and are used to connect the rotating support rod 11 so that the rotating support rod 11 can rotate around it and transmit the movement of the movable push block 7.
[0041] Rotary support rod 11: Two rotating support rods 11 are respectively rotatably connected to the surfaces of two rotating shafts 10. By rotating, they drive the rotating roller 14 and other components to move. They also play a role in positioning and fixing the mold during mold positioning. They are subjected to a large pressure and can ensure the stability of the mold fixing.
[0042] Connecting bridge plate 12: Two connecting bridge plates 12 are slidably connected to the bottom of the two sliders 3 on the left and the two sliders 3 on the right, respectively, and are also slidably installed inside the mounting base 1. The through groove 13 on its surface is used to install the rotating rod 14, which drives the sliders 3 to slide relative to each other through relative sliding.
[0043] Through groove 13: It is formed on the surface of the two connecting bridge plates 12 and is used to install the rotating rod 14 so that the rotating rod 14 can rotate in the through groove 13 and slide under the drive of the rotating support rod 11, thereby driving the connecting bridge plate 12 and the slider 3 to move.
[0044] Rotating rod 14: Two rotating rods 14 are respectively rotatably connected inside the two through slots 13. Under the drive of the rotating support rod 11, they slide relative to each other, thereby driving the connecting bridge plate 12 to slide relative to each other, thus driving the slider 3.
[0045] Limiting slot 15: It is formed on the top wall of the mounting base 1 and is used in conjunction with the limiting block 16 on the top of the movable push block 7. When the movable push block 7 slides, the limiting block 16 slides in the limiting slot 15. Through this cooperation, the limiting block 16 and the movable push block 7 are guided and positioned to ensure the stability of the movable push block 7 during the forward and backward sliding process, prevent it from tilting, and ensure the reliability of the equipment operation.
[0046] Limiting block 16: It is fixedly connected to the top of the movable push block 7. When the movable push block 7 slides, it slides in the limiting slot 15 on the top wall of the mounting base 1. Together with the limiting slot 15, it guides and positions the sliding of the movable push block 7, ensuring that the movable push block 7 can slide back and forth stably. It is one of the important structures to ensure the normal operation of the equipment.
[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
