Description

Technical Field

[0001] This utility model relates to the field of mold changing tooling technology, specifically a positioning structure for quick mold changing tooling. Background Technology

[0002] Quick-change tooling is a process improvement method that uses industrial engineering approaches to minimize mold changeover time, production start-up time, and setup time. It is particularly widely used in machining centers.

[0003] The positioning structure principle of quick mold change tooling relies on advanced zero-point positioning technology. Through precise arrangement and matching, high repeatability positioning accuracy, and adaptability to various working environments, it realizes the rapid, accurate, and reliable replacement and positioning of molds or fixtures.

[0004] In production environments such as turning, the stability of tooling accuracy is crucial to production efficiency and product quality. However, due to the complexity of tooling structures, the stability of quality is often challenged, leading to unstable tooling accuracy, which in turn affects the machining accuracy of products and reduces production efficiency. Therefore, a positioning structure for quick mold change tooling is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the stability of tooling accuracy is crucial for production efficiency and product quality in manufacturing environments such as turning. However, due to the complexity of tooling structures, the stability of quality is often challenged, leading to unstable tooling accuracy, which in turn affects the machining accuracy of products and reduces production efficiency. This invention proposes a positioning structure for quick mold change tooling.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A positioning structure for a quick mold change tooling, comprising a base; through holes are provided on opposite ends of the upper two sides of the base, and sliders are slidably installed in the through holes. Both ends of the sliders penetrate the base, and a clamping plate is fixedly installed at the upper end, and a toothed plate is fixedly installed at the lower end. A sliding hole is provided on one side of the clamping plate, and an adjusting box is fixedly installed on the outer side of the clamping plate. Sliding plates are slidably installed at both ends inside the adjusting box. A threaded hole is provided at one end of the sliding plate, and the other end is slidably disposed in the sliding hole. The clamping plate has a bidirectional screw installed inside the adjustment box. Both ends of the bidirectional screw are rotatably mounted in the adjustment box via bearings. The sliding plate is slidably mounted on both ends of the bidirectional screw. A positioning seat is fixedly mounted on the other end of the sliding plate. A limit hole is opened on the top of the positioning seat, and a limit block is slidably mounted inside the limit hole. The lower end of the limit block passes through the positioning seat and is fixedly mounted with a wedge-shaped fixing block. By adjusting the bidirectional screw, the position of the positioning seat can be quickly adjusted, and the wedge-shaped fixing block can be used to achieve rapid positioning and stable clamping of the mold, simplifying the mold changing process and improving production efficiency.

[0007] Preferably, the upper sides of the base are provided with sliding grooves, and the bottom ends of the clamping plate are slidably installed in the sliding grooves. The sliding cooperation between the sliding grooves and the clamping plate ensures the stable sliding of the clamping plate on the base, while restricting the direction of movement of the clamping plate and preventing it from deviating or shaking during movement.

[0008] Preferably, an adjustment motor is fixedly installed at the same end of the adjustment box. The rotating shaft of the adjustment motor is fixedly connected to the bidirectional screw. The adjustment motor enables the electric drive of the bidirectional screw, thereby allowing convenient control of the sliding plate's movement speed and position.

[0009] Preferably, the positioning seat has a mounting hole on one side, and a slide rod is slidably installed in the mounting hole. One end of the slide rod passes through the positioning seat and is fixedly installed on the wedge-shaped fixing block. A spring is provided between the wedge-shaped fixing block and the positioning seat and is fitted onto the slide rod. The connection between the slide rod and the wedge-shaped fixing block, as well as the setting of the spring, together constitute a stable clamping mechanism for the mold. When the mold is placed on the positioning seat, the wedge-shaped fixing block will automatically adjust its position under the action of the spring to ensure that the mold is firmly clamped.

[0010] Preferably, slide rails are fixedly installed on both sides of the bottom of the base, and a stop block is fixedly installed in the middle of the slide rails at the bottom of the base. The toothed plate is slidably disposed between the slide rails and the stop block. The design of the slide rails and the stop block provides stable guidance and limitation for the movement of the toothed plate.

[0011] Preferably, the upper center of the stop block has a groove, and a rotary motor is fixedly installed at the bottom. The rotating shaft of the rotary motor passes through the stop block and a gear is fixedly installed thereon. The teeth of the gear mesh with the tooth grooves on the gear plate. By rotating the rotary motor, the position of the gear plate can be easily adjusted, thereby achieving rapid positioning and fixing of the mold.

[0012] The advantages of this utility model are:

[0013] 1. This utility model achieves rapid positioning and fixing by activating an adjusting motor and a rotating motor during workpiece processing when mold replacement is required. This releases the mold fixed to the upper part of the base, removes the mold from the base, and places a new mold on top. The rotating motor then drives a gear to rotate, causing two toothed plates to slide relative to each other between a stop and a slide rail. The toothed plates, through a slider, move a clamping plate to both sides of the mold, fixing and positioning both sides. Activating the adjusting motor then drives a bidirectional screw to rotate, causing one end of a sliding plate to slide within an adjusting box. The other end of the sliding plate moves a positioning seat to the other sides of the mold, using wedge-shaped fixing blocks to position and fix the other sides of the mold. This design solves the problem that in production environments such as turning, the stability of tooling accuracy is crucial for production efficiency and product quality. However, due to the complexity of the tooling structure, the stability of quality is often challenged, leading to unstable tooling accuracy, which in turn affects the processing accuracy of the product and reduces production efficiency. This invention improves both production efficiency and product quality. Attached Figure Description

Both ends of the sliders 12 penetrate the base 1, with a clamping plate 2 fixedly installed at the upper end and a toothed plate 17 fixedly installed at the lower end. A sliding hole is formed on one side of the clamping plate 2, and an adjusting box 3 is fixedly installed on the outer side of the clamping plate 2. Slide plates 6 are slidably installed at both ends inside the adjusting box 3. One end of the slide plate 6 has a threaded hole, and the other end is slidably positioned within the sliding hole and penetrates the clamping plate 2.

During operation, when the mold needs to be changed during workpiece processing, the adjusting motor 4 and the rotating motor 15 are started to release the mold fixing on the upper part of the base 1, remove the mold from the base 1, and then place the new mold on the upper part of the base 1. The rotating motor 15 is started to drive the gear 16 to rotate, and the gear 16 drives the two side tooth plates 17 to slide relative to each other between the stop block 14 and the slide rail 13. The tooth plates 17 drive the clamping plate 2 to move to both sides of the mold through the slider 12 to fix and position the two sides of the mold.

The other end of the slide plate 6 drives the positioning seat 7 to move to the other two sides of the mold, and the wedge-shaped fixing block 9 fixes and positions the other two sides of the mold.

[0023] The base 1 has sliding grooves on both sides of its upper part, and the bottom ends of the clamping plate 2 are slidably installed in the sliding grooves. During operation, when the mold needs to be changed during the workpiece processing, the clamping plate 2 starts to move under the action of the slider 12, and at the same time, its bottom ends slide in the sliding grooves on the upper part of the base 1, which ensures the stable sliding of the clamping plate 2 on the base 1, and restricts the direction of movement of the clamping plate 2 to prevent it from deviating or shaking during the movement.

[0024] Each of the adjustment boxes 3 is fixedly installed with an adjustment motor 4 at the same end. The rotating shaft of the adjustment motor 4 is fixedly connected to the bidirectional screw 5. During operation, when it is necessary to change the mold during the workpiece processing, the adjustment motor 4 is started. The rotating shaft of the adjustment motor 4 drives the bidirectional screw 5 to rotate. The bidirectional screw 5 drives the positioning seat 7 to position and fix the two sides of the mold through the sliding plate 6.

[0025] The positioning seat 7 has an installation hole on one side, and a slide rod 10 is slidably installed in the installation hole. One end of the slide rod 10 passes through the positioning seat 7 and is fixedly installed on the wedge-shaped fixing block 9. A spring 11 is provided between the wedge-shaped fixing block 9 and the positioning seat 7 and is fitted onto the slide rod 10. During operation, when the mold needs to be changed during the workpiece processing, when the wedge-shaped fixing block 9 in the positioning seat 7 comes into contact with one side of the mold, the mold pushes the wedge-shaped fixing block 9 to slide in the positioning seat 7 under the action of the limiting block 8, and at the same time drives the slide rod 10 to slide in the positioning seat 7, compressing the spring 11, and fixing and positioning both sides of the mold through the wedge-shaped fixing block 9.

[0026] The base 1 has slide rails 13 fixedly installed on both sides of its bottom. A stop block 14 is fixedly installed in the middle of the slide rail 13 at the bottom of the base 1. The toothed plate 17 is slidably disposed between the slide rail 13 and the stop block 14. During operation, when the mold needs to be changed during the workpiece processing, the toothed plate 17 starts to slide between the stop block 14 and the slide rail 13 after being subjected to force, and drives the clamping plate 2 to move through the slider 12.

[0027] The upper center of the stop block 14 has a groove, and a rotary motor 15 is fixedly installed at the bottom. The rotating shaft of the rotary motor 15 passes through the stop block 14 and a gear 16 is fixedly installed thereon. The teeth on the gear 16 mesh with the tooth grooves on the tooth plate 17. During operation, when it is necessary to change the mold during the workpiece processing, the rotary motor 15 is started to drive the gear 16 to rotate. The gear 16 drives the tooth plates 17 on both sides to slide between the stop block 14 and the slide rail 13.

[0028] Working principle: When it is necessary to change the mold during the workpiece processing, start the adjusting motor 4 and the rotary motor 15 to release the mold fixed on the upper part of the base 1, remove the mold from the base 1, and then place the new mold on the upper part of the base 1. Start the rotary motor 15 to drive the gear 16 to rotate. The gear 16 drives the toothed plates 17 on both sides to slide relative to each other between the stop block 14 and the slide rail 13. The toothed plates 17 drive the clamping plate 2 to move to both sides of the mold through the slider 12 to fix and position the mold on both sides. Start the adjusting motor 4 to drive the bidirectional screw 5 to rotate. The bidirectional screw 5 drives one end of the slide plate 6 to slide in the adjusting box 3. The other end of the slide plate 6 drives the positioning seat 7 to move to the other sides of the mold. When the wedge-shaped fixing block 9 in the positioning seat 7 contacts one side of the mold, the mold pushes the wedge-shaped fixing block 9 to slide in the positioning seat 7 under the action of the limiting block 8. At the same time, it drives the slide rod 10 to slide in the positioning seat 7 and compress the spring 11. The wedge-shaped fixing block 9 is used to position and fix the other sides of the mold, completing the quick mold change.
