Description

Technical Field

[0001] This utility model belongs to the field of positioning mechanisms, specifically, it relates to a mold processing clamping and positioning mechanism. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping.

[0003] Chinese patent CN216359526U discloses a mold processing clamping and positioning mechanism. The mechanism has a movable mechanism that can easily drive two support arms to move towards each other. The clamping distance can be adjusted by adjusting two clamping blocks through a slide rail, which can facilitate the clamping and positioning of the mold by the clamping blocks. The mechanism has a simple structure and fast clamping speed.

[0004] However, in the above-mentioned mold processing clamping and positioning mechanism, the clamping blocks are adjusted individually on the slide rail. When changing the mold, it is necessary to adjust the four clamping blocks in sequence, which makes it difficult to ensure that the four clamping blocks are symmetrical in pairs. When clamping the mold, it is easy to cause uneven force on the mold and affect the mold positioning effect.

[0005] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-3 As shown, this embodiment provides a mold processing clamping and positioning mechanism, including a base 1, a support platform 2 fixed on the upper side of the base 1, two positioning seats 3 slidably engaged with each other on the upper side of the support platform 2, a first driving mechanism 4 for driving the two positioning seats 3 to slide towards each other on the upper side of the base 1, two clamping blocks 5 slidably engaged with each other on one side of the positioning seats 3, a first bidirectional threaded rod 6 rotatably engaged with the two clamping blocks 5 on one side of the positioning seats 3, a worm gear 7 rotatably engaged with the first bidirectional threaded rod 6 on one side of the positioning seats 3, a second driving mechanism 8 on the upper side of the support platform 2, and the worm gear 7 slidably sleeved on the movable end of the second driving mechanism 8.

[0028] By placing the mold on the support platform 2, the second drive mechanism 8 is activated to drive the two worm gears 7 to rotate synchronously. The worm gears 7 drive the two clamping blocks 5 to slide towards each other through the first bidirectional threaded rod 6, which facilitates quick adjustment of the position of the four clamping blocks 5 and keeps the four clamping blocks 5 symmetrical in pairs, thus maintaining the stability of the mold positioning. The first drive mechanism 4 is activated to drive the two positioning seats 3 to slide towards each other, and the mold is clamped by the four clamping blocks 5, which is convenient for adapting to the positioning of molds of different sizes.

[0029] Please see Figure 2As shown, in this embodiment, the positioning seat 3 has a T-shaped channel 9 on one side, and the clamping block 5 has a T-shaped plate structure at one end. The clamping block 5 is slidably fitted in the T-shaped channel 9. The first bidirectional threaded rod 6 is rotatably fitted on the inner wall of the T-shaped channel 9, which facilitates the sliding of the clamping block 5 through the T-shaped channel 9 and improves the sliding stability of the clamping block 5. A bearing is embedded on one side of the positioning seat 3. The outer side of the first end of the worm 7 has a smooth curved surface. The first end of the worm 7 is fixed in the bearing, which facilitates the improvement of the rotational stability of the worm 7 through the bearing. A worm wheel 10 is fixedly sleeved on one end of the first bidirectional threaded rod 6. The second end of the worm 7 extends into the T-shaped channel 9 and meshes with the worm wheel 10. The threads at both ends of the first bidirectional threaded rod 6 are opposite in direction. The two ends of the first bidirectional threaded rod 6 are threadedly fitted with the two clamping blocks 5 respectively, which facilitates the worm 7 to drive the two clamping blocks 5 to slide towards each other through the worm wheel 10 and the first bidirectional threaded rod 6.

[0030] Please see Figure 1-2 As shown, the second drive mechanism 8 in this embodiment includes a first servo motor 801 fixed on the upper side of the support platform 2 and a polygonal transmission shaft 802 fixed at the output end of the first servo motor 801. One end of the worm gear 7 is provided with a polygonal hole 11 corresponding to the polygonal transmission shaft 802. The worm gear 7 is slidably sleeved on the polygonal transmission shaft 802 through the polygonal hole 11, so that when the positioning seat 3 slides, the worm gear 7 slides on the polygonal transmission shaft 802 through the polygonal hole 11, so that the worm gear 7 slides synchronously with the positioning seat 3. This facilitates the second drive mechanism 8. The first servo motor 801 drives the polygonal transmission shaft 802 to rotate, and the polygonal transmission shaft 802 drives the two worm gears 7 to rotate synchronously. The worm gear 7 drives the two clamping blocks 5 to slide towards each other through the worm wheel 10 and the first bidirectional threaded rod 6, so as to quickly adjust the position of the four clamping blocks 5.

[0031] Please see Figure 1-3 As shown, in this embodiment, a plurality of raised columns 12 are fixed on the upper side of the base 1, and the support platform 2 is fixed on the upper side of the plurality of raised columns 12. The upper side of the support platform 2 is provided with a cross-shaped opening groove 13, and the bottom end of the positioning seat 3 is provided with a cross-shaped protrusion 14. The cross-shaped protrusion 14 is slidably engaged in the cross-shaped opening groove 13, which facilitates the sliding of the cross-shaped protrusion 14 through the cross-shaped opening groove 13, thereby improving the sliding stability of the positioning seat 3. The first driving mechanism 4 includes a second servo motor 401 fixed on the upper side of the base 1 and a second bidirectional threaded rod 402 provided at the output end of the second servo motor 401. The threads at both ends of the second bidirectional threaded rod 402 are opposite in direction, and the two ends of the second bidirectional threaded rod 402 are respectively threadedly engaged with the two cross-shaped protrusions 14, which facilitates the second servo motor 401 to drive the second bidirectional threaded rod 402 to drive the two cross-shaped protrusions 14 to slide towards each other, thereby driving the two positioning seats 3 to slide towards each other. The mold is clamped by four clamping blocks 5, which facilitates the positioning of molds of different sizes.

[0032] Please see Figure 1-3As shown, the support platform 2 in this embodiment is provided with a third servo motor 15 at the bottom and a groove on the upper side of the support platform 2. A turntable 16 is rotatably fitted in the groove. The output shaft of the third servo motor 15 extends into the groove and is fixedly connected to the turntable 16. This makes it convenient to release the clamping block 5 from limiting the mold when it is necessary to rotate the mold, and then turn on the third servo motor 15 to drive the turntable 16 to rotate, thereby driving the mold to rotate and improving the convenience of adjusting the rotation of the mold.

[0033] Working principle: The mold is placed on the turntable 16. The second drive mechanism 8 is activated, and the first servo motor 801 drives the polygonal transmission shaft 802 to rotate. The polygonal transmission shaft 802 drives the two worm gears 7 to rotate synchronously. The worm gears 7 drive the two clamping blocks 5 to slide towards each other through the worm wheel 10 and the first bidirectional threaded rod 6, which facilitates quick adjustment of the position of the four clamping blocks 5 and keeps the four clamping blocks 5 symmetrical in pairs, thus maintaining the stability of the mold positioning. The first drive mechanism 4 is activated, and the second servo motor 401 drives the second bidirectional threaded rod 402 to drive the two cross-shaped protrusions 14 to slide towards each other, which in turn drives the two positioning seats 3 to slide towards each other. The mold is clamped by the four clamping blocks 5, which is convenient for accommodating the positioning of molds of different sizes. When it is necessary to rotate the mold, the clamping blocks 5 are released from their position on the mold. Then, the third servo motor 15 is activated to drive the turntable 16 to rotate, which in turn drives the mold to rotate, improving the convenience of adjusting the mold rotation.
