DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-3 A device for smoothing the mouth of a molding sand filling box comprises a base 1. A symmetrical slide groove 2 is provided at the upper end of the base 1. A slide rail 3 is fixedly connected in the slide groove 2. A moving part is slidably connected to the slide rail 3. An auxiliary vibrating part is rotatably connected to the upper end of the moving part. A smoothing part is arranged at the upper end of the auxiliary vibrating part. The smoothing part comprises a scraper 16. The scraper 16 is adjustable in height and its direction can be replaced in opposite directions.
[0021] The specific working principle and implementation method are as follows: the base 1 is placed on the ground and the sand box is placed on the upper end of the base 1. Slide grooves 2 are provided on both sides of the base 1. Slide rails 3 are fixed in the slide grooves 2. Moving parts are slidably connected to the slide rails 3. The moving parts can drive the auxiliary vibrating parts to move. The auxiliary vibrating parts contact with both sides of the sand box when moving, and the sand box is vibrated by the auxiliary vibrating parts, so that the molding sand inside the sand box is more compacted. At the same time, when the auxiliary vibrating parts move, the smoothing parts drive the upper end of the sand box to contact and slide to scrape out the excess molding sand. The scraper 16 can be adjusted up and down according to the height of the sand box, and the scraper 16 can change the scraping direction; the advantage of such a design is that after the sand box is placed on the base 1, the staff moves the smoothing parts back and forth, the moving parts move on the slide rails 3, the scraper 16 can move up and down to adjust the height, and the scraper 16 moves back and forth on the sand box to scrape the molding sand flat, and the auxiliary vibrating parts can vibrate the side walls of the sand box, and the molding sand can be compacted in the sand box, so that the quality of mold manufacturing is better.
[0022] like Figure 3 As shown, the auxiliary vibration member includes a vertical rod 9, a rotation groove 10 is provided at the upper end of the vertical rod 9, and the smoothing member also includes an adjusting rod 12. The lower end of the adjusting rod 12 is fixedly connected with a swivel head 11, and the swivel head 11 is rotatably connected in the rotation groove 10. The adjusting rod 12 is slidably connected to a connecting seat 13 up and down, and mounting grooves 15 are provided on the opposite surfaces of the two connecting seats 13. The scraper 16 is inserted in the mounting groove 15, and a fixing button 14 is threadedly connected to the outer end of the connecting seat 13. The end of the fixing button 14 is abutted against the adjusting rod 12. A rotation groove 10 is provided at the upper end of the vertical rod 9, and the connecting head swivel head 11 is rotated in the rotation groove 10. The upper end of the swivel head 11 is fixedly connected with the adjusting rod 12, and the adjusting rod 12 slides up and down to connect the seat 13. The connecting seat 13 is provided with a mounting groove 15, and the mounting groove 15 is arranged in an "X" shape. The scraper 16 can be inserted and placed at both ends.
[0023] like Figure 2 As shown, the moving part includes a roller 4, which is slidably arranged on the slide rail 3, and the upper end of the roller 4 is rotatably connected to a connecting rod 6. The auxiliary vibrating part also includes a gear 5, and the gear 5 is rotatably connected to the connecting rod 6. A toothed plate 7 is fixedly connected to one side of the slide groove 2 on the base 1, and the toothed plate 7 is meshingly connected to the gear 5. The upper end of the connecting rod 6 is fixedly connected to the lower end of the vertical rod 9, and the outer side wall of the vertical rod 9 is fixedly connected to a ligament 18, and the end of the ligament 18 is fixedly connected to an impact ball 19. The roller 4 moves on the slide rail 3, a gear 5 is fixed to the outer end of the connecting rod 6, and the gear 5 is meshed with the tooth plate 7. When the roller 4 moves, the gear 5 can mesh with the tooth plate 7 and move, and the vertical rod 9 is driven to rotate by the gear 5. The upper end of the vertical rod 9 is rotatably connected with the adjusting rod 12, and the lower end of the vertical rod 9 is rotatably connected with the roller 4. Then, the vertical rod 9 drives the ligament 18 and the impact ball 19 to move, and the impact ball 19 contacts and impacts the side wall of the sand box, so that the sand box can be vibrated to compact the internal molding sand through the impact.
[0024] like Figure 1 As shown, a protective strip 8 is fixedly connected to the other side of the slide groove 2 on the base 1. The protective strip 8 is arranged on the outside of the gear 5. The protective strip 8 is fixed on the side opposite to the tooth plate 7. The protective strip 8 covers the outer end of the gear 5, which can prevent external operations from affecting the movement of the gear 5 during actual use.
[0025] like Figure 3 As shown, a handle 17 is fixedly connected to the outer end of the connecting seat 13, and an anti-slip sleeve is fixedly connected to the outer end of the handle 17. The handle 17 fixed to the outer end of the connecting seat 13 can facilitate the user to move through the handle 17, and pushing the handle 17 can drive the overall movement.
[0026] like Figure 2 As shown, the lower end of the tooth plate 7 is recessed, and the lower edge of the gear 5 is slidably arranged in the recess. The recessed setting of the lower end of the tooth plate 7 can limit the rotation of the gear 5 on the base 1, so as to prevent the gear 5 from falling off during movement.
