Description

Technical Field

[0001] The present invention relates to the technical field of sand casting, and particularly to a sealing structure for the interface of a lower sand storage box of a full-automatic sand casting molding machine. Background Art

[0002] During the process of sand casting, a full-automatic sand casting molding machine is used. The structure of the existing full-automatic sand casting molding machine mainly includes: a frame, a molding and sand blasting device, a sand storage device, and a mold template conveying device arranged on the frame. The sealing structure for the interface of the lower sand storage box in the existing full-automatic sand casting molding machine mainly includes: a lower sand storage box moving assembly and a lower sand feeding box elbow. The lower sand storage box moving assembly is slidably arranged on the column of the frame of the full-automatic sand casting molding machine through sliding sleeves arranged at its four corners. A lower sand storage box and a lower sand blasting plate are arranged on the lower sand storage box moving assembly. A number of sand blasting ports are evenly arranged on the lower sand blasting plate. A wear-resistant interface plate of the lower sand storage box is arranged on the right side of the lower sand storage box. A wear-resistant interface plate of the elbow is arranged on the left side of the lower sand feeding box elbow. When in use, the lower sand storage box moving assembly drives the wear-resistant interface plate of the lower sand storage box to move up and down to realize the connection and closing of the internal cavity between the lower sand storage box and the lower sand feeding box elbow. After long-term use, the wear of the wear-resistant interface plate of the lower sand storage box and the wear-resistant interface plate of the elbow is very serious, affecting the sealing and use effects. At the same time, the manufacturing and replacement costs of the wear-resistant interface plate of the lower sand storage box and the wear-resistant interface plate of the elbow are relatively high.

Adjusting waist holes are respectively arranged on the front and rear two locking blocks. A number of roller bearings are respectively and fixedly arranged on the right sides of the front and rear two locking blocks. Adjusting bolts are respectively arranged on the left sides of the front and rear two locking blocks. The support position of the locking block on the elbow fixing plate can be adjusted through the adjusting bolts, so as to adjust the contact tightness between a number of roller bearings on the locking block and the right side surface of the wear-resistant interface plate of the lower sand storage box, thereby adjusting the frictional force between the wear-resistant interface plate of the lower sand storage box and the wear-resistant interface plate of the elbow, effectively ensuring the service life of the wear-resistant interface plate of the lower sand storage box and the wear-resistant interface plate of the elbow, reducing the replacement frequency and usage cost. At the same time, a quadrilateral sealing strip installation cavity is arranged on the wear-resistant interface plate of the elbow.

The lower sand storage box moving component 1 is slidably arranged on the column of the frame of the fully automatic sand mold casting molding machine through sliding sleeves 11 arranged at its four corners. A lower sand storage box 12 and a lower sand blasting plate 13 are arranged on the lower sand storage box moving component 1. A number of sand blasting ports 14 are evenly arranged on the lower sand blasting plate 13. A connecting bin 15 connected to it is arranged on the right side of the lower sand storage box 12. A number of connecting bin air inlets 151 are evenly arranged at the bottom of the connecting bin 15. A connecting bin fixing plate 16 is arranged on the right side of the connecting bin 15. The right side of the connecting bin fixing plate 16 is fixedly provided with a lower sand storage box wear-resistant interface plate 18 through a number of first fixing bolts 17. An opening 181 matching the connecting bin 15 is arranged on the lower sand storage box wear-resistant interface plate 18. A number of elbow air inlets 21 are evenly arranged at the bottom of the lower sand feeding box elbow 2. An elbow fixing plate 22 is arranged on the left side of the lower sand feeding box elbow 2. The left side of the elbow fixing plate 22 is fixedly provided with an elbow wear-resistant interface plate 24 through a number of second fixing bolts 23. A channel 241 communicating with the inside of the lower sand feeding box elbow 2 is arranged on the elbow wear-resistant interface plate 24. Locking blocks 3 are movably arranged on the front and back sides of the elbow fixing plate 22 through third fixing bolts 25 respectively. Adjusting waist holes 31 are arranged on the front and back two locking blocks 3 respectively. The third fixing bolts 25 pass through the adjusting waist holes 31 matching them and are connected to the elbow fixing plate 22. The elbow fixing plate 22, the elbow wear-resistant interface plate 24, the lower sand storage box wear-resistant interface plate 18 and the connecting bin fixing plate 16 are arranged between the front and back two locking blocks 3. A number of roller bearings 33 are fixedly arranged on the right sides of the front and back two locking blocks 3 through fourth fixing bolts 32 respectively. Adjusting bolts 34 are arranged on the left sides of the front and back two locking blocks 3 respectively. The adjusting bolts 34 pass through the locking blocks 3 and abut against the left side surface of the elbow fixing plate 22. The roller bearings 33 abut against the right side surface of the lower sand storage box wear-resistant interface plate 18. By adjusting the adjusting bolts 34, the supporting position of the locking blocks 3 on the elbow fixing plate 22 can be adjusted, so as to adjust the contact tightness between a number of roller bearings 33 on the locking blocks 3 and the right side surface of the lower sand storage box wear-resistant interface plate 18. Thus, the friction force between the lower sand storage box wear-resistant interface plate 18 and the elbow wear-resistant interface plate 24 is adjusted, so as to effectively ensure the service life of the lower sand storage box wear-resistant interface plate 18 and the elbow wear-resistant interface plate 24, and reduce the replacement frequency and use cost.

Adjusting waist holes 31 are respectively arranged on the front and rear two locking blocks 3. A number of roller bearings 33 are respectively fixedly arranged on the right sides of the front and rear two locking blocks 3. Adjusting bolts 34 are respectively arranged on the left sides of the front and rear two locking blocks 3. The support position of the locking block 3 on the elbow fixing plate 22 can be adjusted through the adjusting bolts 34, so as to adjust the contact tightness between a number of roller bearings 33 on the locking block 3 and the right side surface of the lower sand storage box wear-resistant interface plate 18, thereby adjusting the friction force between the lower sand storage box wear-resistant interface plate 18 and the elbow wear-resistant interface plate 24, effectively ensuring the service life of the lower sand storage box wear-resistant interface plate 18 and the elbow wear-resistant interface plate 24, reducing the replacement frequency and use cost. At the same time, a quadrilateral sealing strip installation cavity 241 is provided on the elbow wear-resistant interface plate 24, and the sealing strip is arranged in the quadrilateral sealing strip installation cavity 241 that cooperates with it to seal between the elbow wear-resistant interface plate 2 and the lower sand storage box wear-resistant interface plate 18, which can better ensure the use effect.
