Description

Technical Field

[0001] This utility model relates to the field of mold positioning technology, and in particular to a mold positioning device with accurate positioning. Background Technology

[0002] Molds, as one of the core process equipment in modern manufacturing, are widely used in many fields such as automobiles, aerospace, electronics, and home appliances. In automobile manufacturing, body stamping dies determine the shape and precision of the car body; in the electronics field, injection molds are used to produce various precision plastic parts. The quality and precision of molds directly affect the quality, performance, and production efficiency of the final product. Precise positioning is crucial during mold use. Traditional mold positioning methods often have many shortcomings. For example, some simple positioning pins or blocks have limited positioning accuracy, making it difficult to meet the requirements of modern high-precision mold processing and forming. During mold installation and replacement, inaccurate positioning can easily lead to misalignment between the mold and the equipment, thus affecting product quality and production efficiency. Moreover, traditional positioning methods have poor adaptability to molds of different sizes and shapes, often requiring additional adjustments or replacements of positioning components, which is cumbersome and time-consuming. Therefore, we propose a mold positioning device with accurate positioning to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a mold positioning device with accurate positioning, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mold positioning device with accurate positioning includes: a mounting frame, a drive motor and four sets of fixing columns are fixedly mounted on the bottom inner wall of the mounting frame, a turntable is fixedly mounted on the output end of the drive motor, four sets of guide rods are slidably mounted inside the turntable, a sliding plate is slidably mounted on the top of each of the four sets of fixing columns, a movable seat is fixedly mounted on the top of each of the four sets of sliding plates, the four movable seats are slidably mounted on the top of the mounting frame, a clamp is fixedly mounted on one side of each of the four sets of movable seats, and the four sets of guide rods are rotatably mounted on the bottom of the corresponding movable seats.

[0006] Preferably, a disc is fixedly mounted at the bottom of the mounting frame, a rotating ring is fixedly mounted at the bottom of the disc, an annular base is rotatably mounted on the outer side of the rotating ring, a mounting seat is fixedly mounted at the bottom of the annular base, a second drive motor is fixedly mounted at the bottom of the mounting seat, a rotating shaft is rotatably mounted on the top of the mounting seat, the top of the rotating shaft is fixedly mounted on the bottom of the disc, a large transmission gear is fixedly mounted on the outer side of the rotating shaft, a small drive gear is fixedly mounted on the output end of the second drive motor, and four sets of support legs are fixedly mounted at the bottom of the mounting seat.

[0007] Preferably, the top of the mounting frame is provided with four sets of slide rails, the four sets of movable seats are slidably installed in the corresponding slide rails, and the four sets of clamps are all anti-slip clamps.

[0008] Preferably, each of the four sets of fixed columns has a groove at its top, and the four sets of sliding plates are slidably installed in the corresponding grooves.

[0009] Preferably, the turntable has four sets of arc-shaped grooves inside, and the four sets of guide rods are slidably installed in the corresponding arc-shaped grooves.

[0010] Preferably, the small drive gear meshes with the large transmission gear, and the annular base has an annular rotating track inside, with the rotating ring rotatably mounted within the annular rotating track.

[0011] In this invention, a mold positioning device with accurate positioning is described. A drive motor drives a small drive gear to rotate. The small drive gear meshes with a large transmission gear, which in turn drives the large transmission gear to rotate, causing the rotating shaft to rotate on the mounting base. This, in turn, drives the turntable to rotate, thereby adjusting the angle of the accurately positioned mold positioning device. By setting a rotating ring at the bottom of the turntable and an annular base at the top of the mounting base, the rotation adjustment of the turntable is made more stable. This transmission method enables high-precision angle control and allows for angle adjustment of the mold positioning device, greatly increasing processing flexibility. For products of different shapes and structures, adjusting the mold angle allows different parts of the mold to better adapt to the processing technology. Furthermore, during mold repair and inspection, the angle adjustment function facilitates technicians in inspecting and maintaining different parts of the mold.

[0012] This utility model features a reasonable structural design. A drive motor rotates the turntable, and through the interaction of the arc-shaped groove, guide rod, and sliding plate, four sets of sliding plates move relative to each other within the grooves of the fixed column. This, in turn, moves the movable seat relative to each other within the corresponding slide rails on the top of the mounting frame, thereby causing the four sets of clamps to move relative to each other. This achieves self-centering and four-way clamping of the mold. This structural design ensures that regardless of any initial offset in the mold's placement, the four sets of clamps automatically adjust and converge towards the center, accurately positioning the mold at the center of the device. This significantly reduces the time required for mold positioning, saving considerable time compared to traditional manual positioning methods. Due to its automatic centering and four-way clamping mechanism, the position and clamping force of the clamps can be quickly adjusted regardless of changes in mold specifications, achieving precise positioning.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-3A mold positioning device with accurate positioning includes: a mounting frame 1, a drive motor 2 and four sets of fixed columns 4 are fixedly installed on the bottom inner wall of the mounting frame 1, a turntable 3 is fixedly installed on the output end of the drive motor 2, four sets of guide rods 6 are slidably installed inside the turntable 3, a sliding plate 5 is slidably installed on the top of each of the four sets of fixed columns 4, a movable seat 7 is fixedly installed on the top of each of the four sets of sliding plates 5, the four movable seats 7 are slidably installed on the top of the mounting frame 1, a clamp 8 is fixedly installed on one side of each of the four sets of movable seats 7, and the four sets of guide rods 6 are rotatably installed on the bottom of the corresponding movable seats 7.

[0019] In this embodiment, a disc 9 is fixedly installed at the bottom of the mounting frame 1, a rotating ring 10 is fixedly installed at the bottom of the disc 9, an annular base 11 is rotatably installed on the outer side of the rotating ring 10, a mounting seat 12 is fixedly installed at the bottom of the annular base 11, a second drive motor 13 is fixedly installed at the bottom of the mounting seat 12, a rotating shaft 15 is rotatably installed at the top of the mounting seat 12, the top of the rotating shaft 15 is fixedly installed at the bottom of the disc 9, a large transmission gear 16 is fixedly installed on the outer side of the rotating shaft 15, a small drive gear 14 is fixedly installed on the output end of the second drive motor 13, and four sets of support legs 17 are fixedly installed at the bottom of the mounting seat 12. This transmission method can achieve high-precision angle control and can adjust the angle of the mold positioning device, greatly increasing the flexibility of processing. For products of different shapes and structures, by adjusting the angle of the mold, the various parts of the mold can be better adapted to the processing technology.

[0020] In this embodiment, four sets of slide rails are provided on the top of the mounting frame 1, and four sets of movable seats 7 are slidably installed in the corresponding slide rails. All four sets of clamps 8 are anti-slip clamps 8. The slide rails provided on the top of the mounting frame 1 provide a precise guide path for the movable seats 7. When the drive mechanism drives the movable seats 7 to move, the slide rails can ensure that the movable seats 7 move along a preset straight line direction.

[0021] In this embodiment, the tops of the four sets of fixed columns 4 are all provided with sliding grooves, and the four sets of sliding plates 5 are slidably installed in the corresponding sliding grooves. This is crucial for achieving precise positioning of the mold, especially in mold processing scenarios with extremely high precision requirements, such as precision injection molds or micro-nano molds. Any tiny deviation may lead to product quality problems, and this precise linear motion guidance can control the positioning error within a very small range.

[0022] In this embodiment, the turntable 3 has four sets of arc-shaped grooves inside, and four sets of guide rods 6 are slidably installed in the corresponding arc-shaped grooves. When positioning molds with complex shapes or high precision requirements, this structure can ensure that the fixture 8 moves accurately toward the center of the mold from all directions, and accurately positions the mold at the center of the device, avoiding mold processing errors caused by positioning deviations.

[0023] In this embodiment, the small drive gear 14 meshes with the large transmission gear 16. An annular rotating track is provided inside the annular base 11, and the rotating ring 10 is rotatably installed in the annular rotating track. By meshing the small drive gear 14 with the large transmission gear 16, the rotation speed is reduced, which can achieve slow and smooth angle adjustment. This is beneficial for protecting the mold and the entire positioning device, and can also control the angle adjustment process more precisely.

[0024] In this embodiment, during use, the mold is placed on top of the mounting frame 1, and the drive motor 2 is started to drive the turntable 3 to rotate. Then, through the cooperation of the arc groove, guide rod 6 and slide plate 5, the four sets of slide plates 5 can move relative to each other in the grooves in the fixed column 4. This drives the moving seat 7 to move relative to each other in the corresponding slide rails on the top of the mounting frame 1, thereby driving the four sets of clamps 8 to move relative to each other, realizing self-centering and four-way clamping of the mold. This structural design can ensure that no matter how the initial placement position of the mold is offset, the four sets of clamps 8 can automatically adjust and move towards the center, accurately positioning the mold in the center position of the device, greatly shortening the time required for mold positioning. Compared with the traditional manual positioning method, it can save a lot of time and cost. Due to its automatic centering and four-way clamping mechanism, no matter how the mold specifications change, the position and clamping force of the clamps 8 can be quickly adjusted to achieve accurate positioning.

[0025] The start-up of drive motor 13 drives the small drive gear 14 to rotate. Through the meshing between the small drive gear 14 and the large transmission gear 16, the large transmission gear 16 is driven to rotate, which in turn drives the rotating shaft 15 to rotate on the mounting base 12, thereby driving the disc 9 to rotate. This, in turn, drives the accurately positioned mold positioning device to adjust its angle. By setting a rotating ring 10 at the bottom of the disc 9 and an annular base 11 at the top of the mounting base 12, the rotation adjustment of the disc 9 is made more stable. This transmission method can achieve high-precision angle control and adjust the angle of the mold positioning device, greatly increasing the flexibility of processing. For products with different shapes and structures, by adjusting the mold angle, the various parts of the mold can be better adapted to the processing technology. At the same time, during mold maintenance and inspection, the angle adjustment function also facilitates technicians to inspect and maintain different parts of the mold.

The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of ​​this utility model.
