Description

Technical Field

[0001] The invention relates to the technical field of lost foam processing, in particular to aging equipment and a process for lost foam casting. Background Art

[0002] Lost foam casting, also known as full-mold casting, is a new casting method in which foam models of the same size as the casting are bonded together to form a model cluster, coated with refractory paint and dried, and then buried in dry quartz sand for vibration molding. Under negative pressure pouring, the model is vaporized, and liquid metal occupies the position of the model. After solidification and cooling, the casting is formed.

[0003] Before adding the foam beads into the mold, the foam needs to be pre-foamed first to expand the foam beads to a certain size. After pre-foaming, the foam beads need to be placed in a dry and ventilated silo for a certain period of time to balance the internal and external pressures of the foam beads, so that the foam beads have elasticity and re-expansion ability, and remove moisture from the surface of the beads. However, in the process of drying the foam beads, because the foams have a certain adsorption force between each other, the foams are closely connected. If only ventilation is used for drying, on the one hand, because the foams are closely connected, they will be separated into blocks when affected by wind, thereby relieving the wind pressure, making it difficult to remove moisture on the surface of a single foam bead, resulting in a long drying process time. On the other hand, when filling, because the foam beads are light in weight and have a certain amount of electrostatic adsorption, during the unloading process, the inner wall of the barrel is prone to adsorb a large number of foam beads, which are difficult to clean and increase the difficulty of unloading.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1 and Figure 3 A aging equipment for lost foam casting comprises a feeding processing mechanism 1, a stirring and separating mechanism 2 is arranged inside the feeding processing mechanism 1, a ventilation and drying mechanism 3 is arranged at the lower end of the feeding processing mechanism 1, a driving transmission mechanism 4 is installed at the right end of the feeding processing mechanism 1, a one-way air collecting mechanism 5 is arranged inside the wind pressure gathering mechanism 6, a feeding solenoid valve 7 is installed on the left side of the feeding processing mechanism 1, a material guide pipe 8 is fixedly connected to the left end of the feeding solenoid valve 7, a pressure relief solenoid valve 9 is installed at the upper end of the feeding processing mechanism 1, and a discharging solenoid valve 10 is installed at the right end of the feeding processing mechanism 1.

[0036] See also Figure 5 The feeding processing mechanism 1 includes a barrel 11, and a plurality of air holes 12 are opened inside the lower side of the barrel 11. The air holes 12 are evenly distributed from left to right. The vertical cross-section of the air holes 12 is a truncated cone, and the diameter of the air holes 12 gradually decreases from top to bottom.

[0037] See also Figure 1 and Figure 3 The pressure relief solenoid valve 9 is located on the upper side of the barrel 11. The pressure relief solenoid valve 9 is fixedly connected to the barrel 11 and passes through the inside of the barrel 11. The discharge solenoid valve 10 is fixedly connected to the right end of the barrel 11. There are two discharge solenoid valves 10, which are located at the front and rear ends of the drive transmission mechanism 4 respectively.

[0038] See also Figure 3 and Figure 4 A diverter block is fixedly installed at the right end of the barrel 11, and the discharge solenoid valve 10 is located on the front and rear sides of the diverter block. The cross-section of the diverter block is an isosceles trapezoid when viewed from above.

[0039] When the foam beads are ventilated and dried, the feed solenoid valve 7 is opened, and the foam beads enter the feed processing mechanism 1 through the material guide pipe 8. At the same time, high-pressure strong wind is introduced into the ventilation and drying mechanism 3, a small part of the wind enters the feed processing mechanism 1, and the other part enters the drive transmission mechanism 4 and drives the stirring and separating mechanism 2 to rotate inside the feed processing mechanism 1, thereby continuously transporting the foam beads entering the feed processing mechanism 1 to the right. After the feed processing mechanism 1 is filled, the feed solenoid valve 7 is closed. At this time, the feed processing mechanism 1 is filled with The interior of the feeding and processing mechanism 1 is in a closed state. Since the ventilation and drying mechanism 3 continuously supplies air evenly to the interior of the feeding and processing mechanism 1, the wind passing through the interior of the feeding and processing mechanism 1 is collected by the one-way wind collecting mechanism 5. The collected wind is gathered and compressed in the wind pressure gathering mechanism 6. When the foam beads in the feeding and processing mechanism 1 are dried, the pressure relief solenoid valve 9 and the discharge solenoid valve 10 are opened. At this time, the high-pressure wind gathered in the wind pressure gathering mechanism 6 will blow the foam beads inside the feeding and processing mechanism 1 through the pressure relief solenoid valve 9 at high pressure, and then be discharged to the outside through the discharge solenoid valve 10.

[0040] See also Figure 5 The ventilation and drying mechanism 3 includes an outer cover 31, the upper end of the outer cover 31 is fixedly connected to the lower end of the barrel 11, a fan blower 32 is fixedly connected to the left side of the inner wall of the outer cover 31, the left end of the fan blower 32 is connected to the outside, and the right end of the fan blower 32 is fixedly connected to a ventilation pipe 33, a plurality of air leakage holes 34 are opened inside the ventilation pipe 33, the air leakage holes 34 are evenly distributed from left to right, and the air leakage holes 34 connect the inside and outside of the ventilation pipe 33.

[0041] When the feeding processing mechanism 1 is filled with foam beads, the fan blower 32 is started, thereby drawing external air into the ventilation pipe 33, increasing the air flow rate inside the ventilation pipe 33, and at the same time, a small part of the flowing air enters the outer cover 31 through the air leakage hole 34. Since the diameter of the air leakage hole 34 is small, the air flow rate in the outer cover 31 is slower than that in the high-pressure flowing air in the ventilation pipe 33, and flows into the barrel 11 through the air vent 12. Since the air vent 12 is an inverted frustum, the air flow rate through the air vent 12 is further reduced, thereby avoiding damage to the foam beads by high-speed flowing air and ensuring the fluidity of the air inside the barrel 11. Since there are multiple air leakage holes 34 and air vents 12, the flowing air in the ventilation pipe 33 is evenly distributed to the inside of the outer cover 31, and the air in the outer cover 31 is evenly distributed to the barrel 11, thereby achieving the effect of uniform ventilation and drying of the foam beads in the barrel 11.

[0042] See also Figure 3 、 Figure 6 and Figure 7The drive transmission mechanism 4 includes a protective shell 41, the left end of the protective shell 41 is fixedly connected to the right end of the barrel 11, a cavity 42 is opened inside the protective shell 41, a transmission hollow tube 43 is rotatably connected inside the cavity 42, and a force-bearing plate 44 is fixedly connected to the annular surface of the transmission hollow tube 43, an air inlet hole 45 is opened inside the protective shell 41 and located at the lower end of the cavity 42, the air inlet hole 45 is connected to the cavity 42, the right end of the ventilation pipe 33 is fixedly connected to the outer wall of the protective shell 41, the interior of the ventilation pipe 33 is connected with the air inlet hole 45, a reflux chamber 47 is opened inside the protective shell 41 and located at the right end of the cavity 42, a connecting pipe 46 is opened inside the protective shell 41 and located at the upper end of the force-bearing plate 44, the connecting pipe 46 connects the force-bearing plate 44 and the reflux chamber 47, the right end of the transmission hollow tube 43 is located inside the reflux chamber 47, and the transmission hollow tube 43 is connected to the inside of the reflux chamber 47.

[0043] See also Figure 4 and Figure 8 The stirring and separating mechanism 2 includes a through rod 21, the right end of the through rod 21 is fixedly connected to the left end of the transfer empty pipe 43, the interior of the through rod 21 is connected to the interior of the transfer empty pipe 43, a spiral plate 22 is fixedly installed on the surface of the through rod 21, and a plurality of air outlet holes 23 are opened on the surface of the through rod 21.

[0044] The high-speed flowing air inside the ventilation pipe 33 moves to the right and enters the cavity 42 through the air inlet hole 45. As the air flows at a high speed, the force-bearing plate 44 is driven to rotate. After the force-bearing plate 44 rotates, it drives the transmission tube 43 to rotate, and then drives the through rod 21 and the spiral plate 22 to rotate. Because the spiral plate 22 is spiral-shaped, on the one hand, it is convenient for the foam beads entering the barrel 11 from the material guide pipe 8 to quickly fill the barrel 11, and at the same time, it accelerates the rapid separation of the foam beads from the barrel 11, saving operation time. On the other hand, the through rod 21 drives the spiral plate 22 to rotate continuously, so that the foam beads inside the barrel 11 are always in motion, thereby greatly increasing the gap between the foam beads and the flowing air. The contact surface accelerates the evaporation of water on the surface of the foam beads. At the same time, the high-speed flowing air at this time has a greatly reduced flow rate after passing through the longer path of the ventilation pipe 33 and pushing the force-bearing plate 44 to rotate. The air with reduced flow rate enters the reflux chamber 47 through the connecting pipe 46. Since the interior of the transfer air pipe 43 is connected with the interior of the reflux chamber 47, the air with reduced flow rate enters the interior of the transfer air pipe 43 under the squeeze of the subsequent air, and finally passes into the interior of the through rod 21, and is ejected from the air outlet 23. The air outlet 23 is located on the surface of the through rod 21, that is, located in the middle of the barrel 11, so that the ejected flowing air can effectively ventilate the overall foam beads from the middle to the outside, thereby accelerating the drying of the foam beads.

[0045] See also Figure 9The one-way air collecting mechanism 5 includes a straight cylinder 51, the surface of the straight cylinder 51 is fixedly connected to the inner side of the upper side of the barrel 11, the inner wall of the straight cylinder 51 is fixedly connected to a fixed plate 52, the middle of the fixed plate 52 is slidably connected to a slide rod 53, the lower end of the slide rod 53 is fixedly connected to a plug 54, a compression spring 55 is fixedly connected between the fixed plate 52 and the plug 54, the compression spring 55 is sleeved on the surface of the slide rod 53, and a guide rod 56 is slidably connected on the plug 54 and on both sides of the slide rod 53. The guide rod 56 passes through the inside of the plug 54, and the upper end of the guide rod 56 is fixedly connected to the lower end of the fixed plate 52. A sealing block 57 is fixedly connected to the inner wall of the straight cylinder 51 and located on the outside of the plug 54. The lower end of the straight cylinder 51 is fixedly connected to a filter plate 58, and the filter plate 58 is arc-shaped.

[0046] See also Figure 10 The wind pressure gathering mechanism 6 includes a fixed shell 61, the lower end of the fixed shell 61 is fixedly connected to the upper end of the barrel 11, an air cavity 62 is opened inside the fixed shell 61, a water-absorbing sponge 63 is fixedly connected to the inner wall of the air cavity 62 and located on the left side of the one-way air collecting mechanism 5, a wind compressor 64 is fixedly connected to the inner wall of the fixed shell 61 and located on the left side of the water-absorbing sponge 63, the surface of the straight cylinder 51 is fixedly connected to the right side of the inside of the fixed shell 61, and the lower end of the straight cylinder 51 passes through the inside of the barrel 11.

[0047] As the gas inside the barrel 11 gradually increases, the internal pressure of the barrel 11 also gradually increases, so that the plug 54 is pushed upward, and then the plug 54 overcomes the elastic force of the compression spring 55 under the guidance of the guide rod 56 and moves upward, thereby moving to the upper end of the sealing block 57. At this time, the air inside the barrel 11 flows into the gap between the plug 54 and the sealing block 57, thereby entering the air cavity 62 and gradually moving to the left end of the air cavity 62. When passing through the water-absorbing sponge 63, the water-absorbing sponge 63 absorbs the water contained in the air. The air is absorbed and passed through the wind compressor 64, which compresses the air on the left side of the wind compressor 64. After the foam beads inside the barrel 11 are ventilated and dried, the discharge solenoid valve 10 is opened. At this time, the internal pressure of the barrel 11 is balanced with the external pressure, and the pressure relief solenoid valve 9 is opened again to discharge the compressed air on the left side of the wind compressor 64 into the barrel 11 through the pressure relief solenoid valve 9. The foam beads inside the barrel 11 are subjected to an impact force and are quickly transported outward under the rotation of the stirring and separation mechanism 2.

[0050] S2, ventilation is started inside the ventilation and drying mechanism 3, a small part of the wind enters the feeding and processing mechanism 1, and the other part enters the driving and transmitting mechanism 4 and drives the stirring and separating mechanism 2 to rotate inside the feeding and processing mechanism 1;

After the foam beads in the feeding processing mechanism are dried, the pressure relief solenoid valve and the discharge solenoid valve are opened, and the high-pressure wind gathered inside the wind pressure gathering mechanism blows the foam beads inside the feeding processing mechanism through the pressure relief solenoid valve at high pressure, and then is discharged to the outside through the discharge solenoid valve.
