[0008] The glass mold wet clay sand static pressure line casting method has a wide range of applications in the fields of automobile manufacturing, machine tool manufacturing and shipbuilding. The prior art discloses some invention patents in the field of sand casting technology, among which the invention patent with publication number CN115488324B discloses a sputtering-proof sand mold negative pressure gravity casting equipment, including a workbench, the top of the workbench is fixedly connected to a fixed bracket, the top of the fixed bracket is fixedly connected to a storage device, the bottom of the inner wall of the fixed bracket is fixedly connected to a liquid injection device, and the liquid injection device includes: a liquid injection pipe, the liquid injection pipe has a cylindrical tubular structure, and a connecting frame arranged on the outside of the liquid injection pipe, the connecting frame is fixedly connected to the liquid injection pipe, both ends of the connecting frame are fixedly connected to a lifting rod, a liquid injection head, The injection head has a conical structure and connecting rods arranged on both sides of the injection head, one end of the connecting rod is fixedly connected to the side of the injection head. The present invention relates to the field of sand mold gravity casting technology. The anti-sputtering sand mold negative pressure gravity casting equipment can avoid sputtering during the injection process, facilitate the protection of staff, and avoid the situation where metal liquid splashes and causes damage to the staff. The technical scheme still has some shortcomings in the process of application. The surface of the casting cast by sand mold is prone to rough and uneven undesirable phenomena. This is because the metal liquid enters the casting cavity at too fast a speed, resulting in a large number of tiny air bubbles remaining inside. Moreover, such a casting method will also cause the metal liquid to be unable to completely fill the casting cavity, thereby reducing the gradual edge accuracy.

[0009] Based on this, the present invention designs a glass mold wet clay sand static pressure line casting device and a casting process thereof to solve the above problems. Summary of the invention

[0010] The purpose of the present invention is to solve the problem that the surface of the castings cast by sand casting in the traditional glass mold wet clay sand static pressure line casting device is prone to roughness and unevenness. This is because the metal liquid enters the casting cavity too fast, resulting in a large number of tiny air bubbles remaining inside. In addition, such a casting method will also cause the metal liquid to be unable to completely fill the casting cavity, thereby reducing the gradual edge accuracy. A glass mold wet clay sand static pressure line casting device and a casting process thereof are proposed.

[0011] In order to achieve the above object, the present invention adopts the following technical solutions:

[0016] As a further description of the above technical solution:

[0017] The lifting action generating component comprises a heat-insulating sleeve B clamped to the bottom end of the casting pipe, the space between the heat-insulating sleeve B and the casting pipe is filled with a shape memory polymer composite material, and a heat-absorbing pad is connected to the bottom of the heat-insulating sleeve corresponding to the shape memory polymer composite material;

[0018] A lifting sleeve is sleeved on the casting tube, the bottom end of the lifting sleeve is sleeved in the upper port of the insulation sleeve B, and a semiconductor refrigeration plate is installed on the bottom end of the lifting sleeve.

[0019] As a further description of the above technical solution:

[0020] The casting control assembly comprises a conical head embedded in the casting pipe, a plurality of adapter notches A in a ring array are provided at the edge of the conical head, a flow rate control blade is rotatably connected in the adapter notch A, a adapter is connected under the flow rate control blade, and an umbrella-shaped shaft is rotatably connected inside the adapter;

[0021] A lifting ring is provided below the conical head, and a plurality of transfer notches B are provided on the lifting ring corresponding to the plurality of umbrella-shaped shafts. The other ends of the plurality of umbrella-shaped shafts are rotatably connected in the plurality of transfer notches B respectively. A rotating disk is rotatably connected in the lifting ring, and the casting control assembly also includes a transmission member for realizing the synchronous movement of the lifting sleeve and the rotating disk.

[0022] As a further description of the above technical solution:

[0023] The transmission member includes a lifting plate slidably connected to the lifting slot, a support spring is connected to the lifting plate, the lifting plate is elastically supported and connected to the top of the lifting slot through the support spring, a transmission block is connected between the lifting plate and the lifting sleeve, and a connecting rod is connected between the lifting plate and the rotating disk.

[0024] As a further description of the above technical solution:

[0025] A vibration generating component is sleeved in the casting tube, and the vibration generating component includes a connecting sleeve clamped on the rotating disk, a transmission shaft is sleeved in the connecting sleeve, a through-connecting hole is opened on the conical head corresponding to the transmission shaft, and the end of the transmission shaft is connected to an impeller after passing through the through-connecting hole, the impeller is rotatably connected in the casting tube, and the other end of the transmission shaft is connected to a vibration generating component.

[0026] As a further description of the above technical solution:

[0027] The vibration generating member comprises a vibration sleeve fixedly sleeved on the bottom end of the connecting sleeve, a vibration disk is clamped in the vibration sleeve, a vibration shaft connected to the transmission shaft is rotatably connected in the vibration disk, and an eccentric vibrator is connected to the vibration shaft.

[0028] A glass mold green clay sand static pressure line casting process, comprising the following steps:

[0029] Place the prepared lower sand core on the loading platform, then cover the prepared upper sand core cover on the lower sand core, control the lifting seat to move downward, and drive the casting tube downward through the insulation sleeve A during the downward movement of the lifting seat, and the bottom end of the casting tube moves downward through the casting port to the bottom wall of the inner cavity of the lower sand core, and control the lifting seat to stop the downward movement;

[0030] Add molten metal into the casting hopper, and the molten metal flows out along the casting tube. When the molten metal flows out through the casting tube, the lifting seat is controlled to slowly move upward. The inner cavity structures of the lower sand core and the upper sand core are diversified, that is, the casting amount of molten metal per unit height of the inner cavity of the lower sand core and the upper sand core is different, while the upward speed of the casting tube is constant, and the amount of molten metal flowing into the lower sand core and the upper sand core through the casting tube per unit time remains unchanged. When the molten metal in the lower sand core or the upper sand core submerges the heat absorbing pad, the heat absorbing pad will absorb more heat from the molten metal, and the heat absorbing pad will act on the shape memory polymer composite material with heat, and the shape memory polymer composite material absorbs heat and expands thermally. The shape memory polymer composite material pushes the lifting sleeve to slide upward on the casting tube through the semiconductor refrigeration sheet, and the lifting sleeve drives the lifting plate to slide upward in the lifting groove through the transmission block during the upward rising process, and squeezes the support The spring causes it to undergo elastic deformation. During this process, the lifting plate pushes the adapter plate through the connecting rod, and the adapter plate drives the lifting plate to rise. When the lifting plate approaches the conical head, it will generate an upward thrust on the flow rate control blades on the multiple adapters through multiple umbrella-shaped shafts. The multiple flow rate control blades rotate with the conical head as the transfer point at the same time. After the multiple flow rate control blades are unfolded, they tend to be horizontal. When the height of the heat absorption pad gradually exceeds the height of the metal liquid inside the lower sand core or the upper sand core, the heat transferred by the heat absorption pad to the shape memory polymer composite material per unit time gradually decreases, and the semiconductor refrigeration sheet is in a working state. The heat released by the semiconductor acts on the shape memory polymer composite material. The shape memory polymer composite material gradually recovers its deformation after cooling, and the support spring begins to recover its elastic deformation, and the flow rate control blades in the unfolded state gradually gather together.

[0031] When the molten metal flows through the impeller, it drives the impeller to rotate. The impeller drives the cone head to rotate through the transmission shaft. The cone head drives multiple flow rate control blades to rotate. The flow rate control blades use the adapter to drive the lifting plate to rotate on the adapter plate through the umbrella shaft. The molten metal that is about to flow into the lower sand core or the upper sand core is stirred by rotating the multiple flow rate control blades.

[0032] When the impeller drives the conical head to rotate through the transmission shaft, the transmission shaft will also drive the vibration shaft to rotate in the vibration sleeve. The vibration sleeve drives multiple eccentric vibrators to rotate and generate vibration. The vibration effect acts on the molten metal injected into the lower sand core and the upper sand core through the vibration sleeve.

[0033] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0034] 1. In the present invention, after the multiple flow rate control blades are unfolded, they tend to be horizontal, so that they can hinder the molten metal flowing through and reduce the flow rate of the molten metal. When the height of the heat absorbing pad is gradually higher than the height of the molten metal inside the lower sand core or the upper sand core, the heat transferred by the heat absorbing pad to the shape memory polymer composite material per unit time gradually decreases, and the flow rate control blades in the unfolded state gradually gather together. After the multiple flow rate control blades are folded, the hindering effect on the molten metal is reduced. Therefore, the injection speed of the molten metal can be automatically controlled according to the changes in the internal space structure of the upper sand core and the lower sand core, which can effectively prevent the traditional casting method from casting too fast and causing bubbles in the molten metal in the upper sand core and the lower sand core, effectively reducing the bubbles in the molten metal during casting, so that the molten metal is more completely filled in the upper sand core and the lower sand core.

[0035] 2. In the present invention, multiple flow rate control blades rotate to stir the molten metal that is about to flow into the lower sand core or the upper sand core, thereby ensuring the uniformity of the texture of the molten metal flowing into the lower sand core and the upper sand core.

[0036] 3. In the present invention, the vibration effect acts on the molten metal injected into the lower sand core and the upper sand core through the vibration sleeve, which can not only further play a defoaming role, but also facilitate the molten metal to quickly and completely fill the casting cavity, ensuring the surface accuracy of the casting.

[0057] Specifically, the casting tube 304 is sleeved with a vibration generating component 9, which includes a connecting sleeve 901 that is clamped on the rotating disk, and a transmission shaft 902 is sleeved inside the connecting sleeve 901. A through-connecting hole corresponding to the transmission shaft 902 is opened on the conical head 801, and the end of the transmission shaft 902 is connected to an impeller 903 after passing through the through-connecting hole. The impeller 903 is rotatably connected to the casting tube 304, and the other end of the transmission shaft 902 is connected to a vibration generating component 904.

[0058] Specifically, the vibration generating element 904 includes a vibration sleeve 9041 fixedly sleeved on the bottom end of the connecting sleeve 901, a vibration disk 9042 is clamped in the vibration sleeve 9041, a vibration shaft 9043 connected to the transmission shaft 902 is rotatably connected in the vibration disk 9042, and an eccentric vibrator 9044 is connected to the vibration shaft 9043.

[0059] A glass mold green clay sand static pressure line casting process, comprising the following steps:

[0060] Place the prepared lower sand core 4 on the loading platform 2, then cover the prepared upper sand core 5 on the lower sand core 4, control the lifting seat 301 to move downward, and during the downward movement of the lifting seat 301, drive the casting tube 304 downward through the heat insulation sleeve A303, and the bottom end of the casting tube 304 passes through the casting port 6 and moves downward to the bottom wall of the inner cavity of the lower sand core 4, and control the lifting seat 301 to stop the downward movement;

[0061] The molten metal is added into the casting hopper 305, and the molten metal flows out along the casting pipe 304. When the molten metal flows out through the casting pipe 304, the lifting seat 301 is controlled to slowly move upward. The inner cavity structures of the lower sand core 4 and the upper sand core 5 are diversified, that is, the casting amount of the molten metal per unit height of the inner cavity of the lower sand core 4 and the upper sand core 5 is different, while the upward speed of the casting pipe 304 is constant, and the amount of molten metal flowing into the lower sand core 4 and the upper sand core 4 through the casting pipe 304 per unit time is constant, and the molten metal in the lower sand core 4 or the upper sand core 5 submerges the heat absorbing pad 7. 02, the heat absorbing pad 702 will absorb more heat from the metal liquid, and the heat absorbing pad 702 will act on the shape memory polymer composite material 703. The shape memory polymer composite material 703 absorbs heat and expands. The shape memory polymer composite material 703 pushes the lifting sleeve 704 to slide upward on the casting tube 304 through the semiconductor cooling sheet 705. In the process of lifting upward, the lifting sleeve 704 drives the lifting plate 8081 to slide upward in the lifting groove 11 through the transmission block 8082, and squeezes the support spring 8 084 causes elastic deformation. During this process, the lifting plate 8081 pushes the adapter plate 807 through the connecting rod 8083, and the adapter plate 807 drives the lifting plate 806 to rise. When the lifting plate 806 approaches the conical head 801, it will generate an upward thrust to the flow rate control blades 803 on the multiple adapters 804 through the multiple umbrella-shaped shafts 805. The multiple flow rate control blades 803 rotate at the same time with the conical head 801 as the transfer point. After the multiple flow rate control blades 803 are unfolded, they tend to be horizontal, waiting to be sucked. When the height of the heat pad 702 gradually becomes higher than the height of the metal liquid inside the lower sand core 4 or the upper sand core 5, the amount of heat transferred per unit time from the heat absorbing pad 702 to the shape memory polymer composite material 703 gradually decreases, while the semiconductor refrigeration sheet 705 is in a working state, and the heat released by the semiconductor acts on the shape memory polymer composite material 703. After the temperature is reduced, the shape memory polymer composite material 703 gradually recovers its deformation, and the support spring 8084 begins to recover its elastic deformation, and the flow rate control blades 803 in the expanded state gradually gather together;

[0062] When the molten metal flows through the impeller 903, the impeller 903 is driven to rotate. The impeller 903 rotates through the transmission shaft 902 to drive the conical head 801 to rotate. The conical head 801 drives the plurality of flow rate control blades 803 to rotate. The flow rate control blades 803 use the adapter 804 to drive the lifting plate 806 to rotate on the adapter plate 807 through the umbrella shaft 805. The molten metal that is about to flow into the lower sand core 4 or the upper sand core 5 is stirred by rotating the plurality of flow rate control blades 803.

[0063] When the impeller 903 drives the conical head 801 to rotate through the transmission shaft 902, the transmission shaft 902 will also drive the vibration shaft 9043 to rotate in the vibration sleeve 9041. The vibration sleeve 9041 drives multiple eccentric vibrators 9044 to rotate and generate vibration. The vibration effect acts on the metal liquid injected into the lower sand core 4 and the upper sand core 5 through the vibration sleeve 9041.

[0064] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

A glass mold green clay sand static pressure line casting process, using the glass mold green clay sand static pressure line casting device according to any one of claims 1 to 7 for casting, characterized in that: The following steps are involved: The prepared lower sand core (4) is placed on the loading platform (2), and then the prepared upper sand core (5) is covered on the lower sand core (4), and the lifting seat (301) is controlled to move downward. During the downward movement of the lifting seat (301), the casting tube (304) is driven downward by the heat insulation sleeve A (303), and the bottom end of the casting tube (304) passes through the casting port (6) and moves downward to the bottom wall of the inner cavity of the lower sand core (4), and the lifting seat (301) is controlled to stop the downward movement; Liquid metal is added into the casting hopper (305), and the liquid metal flows out along the casting pipe (304). When the liquid metal flows out through the casting pipe (304), the lifting seat (301) is controlled to slowly move upward. The inner cavity structures of the lower sand core (4) and the upper sand core (5) are diversified, that is, the casting amount of liquid metal per unit height of the inner cavity of the lower sand core (4) and the upper sand core (5) is different, while the upward speed of the casting pipe (304) is constant, and the amount of liquid metal flowing into the lower sand core (4) and the lower sand core (4) through the casting pipe (304) per unit time is constant. When the liquid metal in the lower sand core (4) or the upper sand core (5) is submerged and absorbs heat, the liquid metal in the lower sand core (4) or the upper sand core (5) is submerged and absorbs heat. When the pad (702) is placed on the casting tube (304), the heat absorbing pad (702) will absorb more heat from the molten metal, and the heat absorbing pad (702) will act on the shape memory polymer composite material (703). The shape memory polymer composite material (703) absorbs heat and expands. The shape memory polymer composite material (703) pushes the lifting sleeve (704) to slide upward on the casting tube (304) through the semiconductor cooling plate (705). During the upward lifting process, the lifting sleeve (704) drives the lifting plate (8081) to slide upward in the lifting groove (11) through the transmission block (8082), and squeezes the support The spring (8084) causes elastic deformation. During this process, the lifting plate (8081) pushes the adapter plate (807) through the connecting rod (8083), and the adapter plate (807) drives the lifting plate (806) to rise. When the lifting plate (806) approaches the conical head (801), the multiple umbrella-shaped shafts (805) respectively generate upward thrusts on the flow rate control blades (803) on the multiple adapters (804). The multiple flow rate control blades (803) rotate at the same time with the conical head (801) as the transfer point. After the multiple flow rate control blades (803) are unfolded, they tend to When the height of the heat absorbing pad (702) gradually becomes higher than the height of the metal liquid inside the lower sand core (4) or the upper sand core (5), the amount of heat transferred per unit time from the heat absorbing pad (702) to the shape memory polymer composite material (703) gradually decreases, while the semiconductor refrigeration sheet (705) is in a working state, and the heat released by the semiconductor acts on the shape memory polymer composite material (703). After the temperature is reduced, the shape memory polymer composite material (703) gradually recovers its deformation, the support spring (8084) begins to recover its elastic deformation, and the flow rate control blades (803) in the expanded state gradually gather together; When the molten metal flows through the impeller (903), the impeller (903) is driven to rotate. The impeller (903) rotates through the transmission shaft (902) to drive the conical head (801) to rotate. The conical head (801) drives the plurality of flow rate control blades (803) to rotate. The flow rate control blades (803) use the adapter (804) to drive the lifting plate (806) to rotate on the adapter plate (807) through the umbrella shaft (805). The molten metal that is about to flow into the lower sand core (4) or the upper sand core (5) is stirred by rotating the plurality of flow rate control blades (803). When the impeller (903) drives the conical head (801) to rotate via the transmission shaft (902), the transmission shaft (902) also drives the vibration shaft (9043) to rotate inside the vibration sleeve (9041), and the vibration sleeve (9041) drives the plurality of eccentric vibrators (9044) to rotate and generate vibrations, and the vibration effect acts on the metal liquid injected into the lower sand core (4) and the upper sand core (5) via the vibration sleeve (9041).
