Description

Technical Field

[0001] The present invention relates to the field of casting technology, and particularly to an efficient demolding device for castings. Background Art

[0002] Metal castings have a profound impact on industrial development. As one of the basic processes in the manufacturing industry, casting technology can produce components with complex shapes and precise dimensions, and is widely used in fields such as automobiles, aerospace, mechanical manufacturing, and energy. It not only improves production efficiency, reduces costs, but also promotes the progress of materials science and process technology. Through casting, metal materials can be efficiently utilized, promoting the diversification and performance improvement of industrial products, providing important support for the large-scale, automated, and precision of modern industry, and becoming a key driving force for the industrial revolution and the development of the modern industrial system.

[0003] The demolding process after casting is crucial in the casting process, directly affecting the quality, production efficiency, and cost of castings. Demolding refers to the process of removing the solidified casting from the mold. Improper demolding operations may cause surface damage, cracks, or deformation of the casting, affecting its dimensional accuracy and appearance quality, and even resulting in scrap. A reasonable demolding method can reduce the wear and damage of the mold, extend the service life of the mold, and reduce production costs. The demolding process is closely related to mold design, cooling systems, lubricant use, etc. Optimizing the demolding process helps to improve the overall level of the casting process.

[0004] The Chinese invention patent with the publication number CN110918949B discloses a demolding device for sand mold casting. This device generates vibrations between the sand box, molding sand, and the casting, causing the molding sand and the casting in the sand box to fall off, and at the same time controlling the demolding direction to avoid damage to the casting caused by excessive force during demolding. However, this device cannot remove the casting from a large amount of molding sand, and it is easy to cause collisions between castings when processing multiple castings, reducing the accuracy and yield of the castings. At the same time, it cannot effectively recycle the molding sand, reducing the demolding efficiency of the casting, and the cleaning of the sand box by this device is not thorough enough, and a large amount of molding sand is likely to remain on the sand box, reducing the demolding efficiency.

Detailed implementation manners

[0030] Refer to Figures 1 to 12 As shown in the figure, a high - efficiency demolding device for castings includes a recycling component 1 for recycling sand molds. The recycling component 1 crushes and recycles the molding sand, and screens out the castings in the molding sand, improving the demolding efficiency of the castings. A transfer component 2 is slidably arranged at the upper end of the recycling component 1. The transfer component 2 transports the sand box 201 and adjusts the position of the sand box 201 to prevent the castings from colliding with other castings during demolding. A demolding component 3 is also slidably arranged on the recycling component 1. The demolding component 3 knocks the sand box 201, increasing the dropping speed of the molding sand and the castings in the sand box 201. At the same time, the demolding component 3 can clean the inner wall of the sand box 201, improving the reuse efficiency of the sand box 201. The present invention automatically demolds the castings, improving the demolding efficiency of the castings.

[0031] The recycling component 1 includes a recycling bin 101. An installation groove 103 is provided on the side of the recycling bin 101.

A first spring 108 is arranged between the demagnetizing plate 107 and the recycling bin 101. The demagnetizing plate 107 demagnetizes the molding sand and adsorbs magnetic objects in the molding sand. When the molding sand accumulates too much at the lower end of the recycling bin 101, the sealing plate 102 is driven to slide on the recycling bin 101, and the recycling bin 101 releases the closure of the sealing plate 102. At this time, the molding sand is discharged through the discharge port at the bottom of the recycling bin 101. When it is necessary to take out the casting in the recycling bin 101, the screening rack 105 is driven to slide on the recycling bin 101. When the screening rack 105 rises, it pushes out the casting. At the same time, a plurality of groups of sieve plates 106 are driven to slide back and forth on the screening rack 105 to shake off the molding sand on the casting, improving the demolding efficiency of the casting.

A cleaning head 304 slides inside the first cleaning frame 303. Multiple sets of first cleaning rods 305 are rotatably arranged on the cleaning head 304. A second cleaning rod 306 slides inside the first cleaning rod 305. After the castings and molding sand in the sand box 201 fall into the recycling box 101, the first flap 301 is driven to rotate. The first flap 301 drives the first cleaning frame 303 and the cleaning head 304 to insert into the sand box 201. The cleaning head 304 is driven to slide inside the first cleaning frame 303. The first cleaning frame 303 drives multiple sets of first cleaning rods 305 to move, adjusting the positions of the first cleaning rods 305. The second cleaning rod 306 is driven to slide inside the first cleaning rod 305. After the second cleaning rod 306 is in contact with the inner wall of the sand box 201, the first cleaning frame 303 is driven to rotate on the first flap 301. The first cleaning frame 303 drives the cleaning head 304 to rotate. The cleaning head 304 drives the first cleaning rods 305 and the second cleaning rod 306 to rotate.

[0034] Working principle: During operation, place the sand box 201 on the support plate 204, drive the two sets of stabilizing plates 205 to approach each other, and the stabilizing plates 205 clamp the sand box 201. Drive the support plate 204 to slide on the installation groove 103, and the support plate 204 drives the sand box 201 to rise. Subsequently, clamp the sand box 201. Drive the first adjusting frame 202 to slide on the recycling box 101, and the first adjusting frame 202 drives the support frame 203 and the clamping frame 206 to move. Drive the support frame 203 to slide on the first adjusting frame 202, and the support frame 203 drives the clamping frame 206 to align with the sand box 201. Drive the two sets of support frames 203 to approach each other, and the support frames 203 drive the first limit block 207 and the second limit block 208 to align with the sand box 201. Drive the first limit block 207 to move, and the first limit block 207 supports the sand box 201. Drive the two sets of second limit blocks 208 to approach each other, and the two sets of second limit blocks 208 clamp the sand box 201. Drive the two sets of stabilizing plates 205 to move away, and drive the first adjusting frame 202 and the support frame 203 to move to transfer the sand box 201.

[0035] After the first adjusting frame 202 drives the sand box 201 to reach between the two second adjusting frames 310, drive the two sets of second adjusting frames 310 to move towards the position of the sand box 201. When the two sets of second adjusting frames 310 reach the working position, stop driving the second adjusting frames 310 to move. Drive the cam 315 to rotate. When the cam 315 rotates, it drives the knocking plate 313 to reciprocate on the installation frame 302, and the knocking plate 313 knocks on the sand box 201 to complete the vibration of the sand box 201. At the same time, drive the knocking head 311 to slide on the installation plate 312. After the knocking head 311 aligns with the side of the sand box 201, drive the installation plate 312 to reciprocate on the second adjusting frame 310, and the installation plate 312 drives the knocking head 311 to knock on the sand box 201, knocking the molding sand and the casting in the sand box 201 to fall into the recycling box 101 to complete the demolding of the casting.

[0036] After the casting and molding sand fall into the recycling box 101, drive the first flap 301 to rotate. The first flap 301 drives the first cleaning frame 303 and the cleaning head 304 to insert into the sand box 201. Drive the cleaning head 304 to slide within the first cleaning frame 303. The first cleaning frame 303 drives multiple groups of the first cleaning rods 305 to move, adjusting the positions of the first cleaning rods 305. Drive the second cleaning rod 306 to slide within the first cleaning rod 305. After the second cleaning rod 306 fits against the inner wall of the sand box 201, drive the first cleaning frame 303 to rotate on the first flap 301. The first cleaning frame 303 drives the cleaning head 304 to rotate. The cleaning head 304 drives the first cleaning rods 305 and the second cleaning rods 306 to rotate.

The second cleaning frame 308 drives the blowing head 309 to move. The second cleaning frame 308 adjusts the position of the blowing head 309 while avoiding collision between the blowing head 309 and the first cleaning rods 305. Drive the blowing head 309 to work. The blowing head 309 blows high-pressure air into the sand box 201 to clean the bonded sand that cannot be cleaned by the clamping frame 206.

[0037] When the casting and molding sand fall into the recycling box 101, drive the screening frame 105 to slide within the recycling box 101. At the same time, drive the sieve plate 106 to reciprocate on the screening frame 105. At this time, the sieve plate 106 drives the casting to shake, and the molding sand on the casting falls off the casting. The broken molding sand enters the recycling box 101 through the leakage holes on the sieve plate 106. Larger pieces of molding sand enter the recycling box 101 through the gaps between multiple groups of sieve plates 106. The casting is lifted by the sieve plate 106 to achieve demolding of the casting. After the molding sand enters the recycling box 101, drive the stirring roller 110 to rotate. The stirring roller 110 further breaks up the molding sand. During the process of further breaking up, drive the adjusting block 109 to slide within the recycling box 101. The adjusting block 109 drives the stirring roller 110 to reciprocate, improving the effect of the stirring roller 110 in breaking up the molding sand. At this time, the molding sand falls onto the bottom of the sealing plate 102. During the process of the molding sand falling, drive the demagnetizing plate 107 to work. The demagnetizing plate 107 adsorbs the magnetic substances in the molding sand, completing the demagnetization of the molding sand. Subsequently, it accumulates at the bottom of the recycling box 101, completing the recycling of the molding sand. When it is necessary to take out the molding sand in the recycling box 101, drive the sealing plate 102 to move on the recycling box 101. The sealing plate 102 releases the closure of the recycling box 101. At this time, the molding sand is discharged through the discharge opening of the sealing plate 102.
