Description

Technical Field

[0001] This invention relates to the field of vacuum die casting technology, specifically to a die casting device for high-strength, tough, and lightweight electrical distribution cabinet structural components. Background Technology

[0002] With the continuous advancement of vacuum die casting technology, some structural components of electrical distribution cabinets are also beginning to be produced using this technology. This technology effectively reduces or eliminates porosity and dissolved gases inside the casting by extracting air from the mold cavity during the die casting process, thus significantly improving the mechanical properties and appearance quality of the casting. However, existing vacuum die casting equipment often introduces air bubbles during material transport. These bubbles can directly enter the mold, adversely affecting product quality. Although some equipment can separate air bubbles from the material through vibration, the separated gas still remains in the transport pipeline and is not completely eliminated. Summary of the Invention

[0003] The purpose of this invention is to provide a die-casting device for high-strength, tough, and lightweight power distribution cabinet structural components, so as to solve at least one technical problem existing in the prior art.

[0007] Preferably, one end of the partition is fixedly connected to a mounting plate, the other end of the partition is fixedly connected to a fixing plate, and the motor is adapted to be installed on the outside of the fixing plate.

[0008] Preferably, a cylinder is adapted to be installed on the outer side of the mounting plate, the output end of the cylinder is fixedly connected to the outer side of the moving mold, and an exhaust valve is provided at the top of the fixed mold.

[0009] Preferably, a support rod is fixedly connected to the outside of the material tube, the other end of the support rod is fixedly connected to the top of the partition, a connecting pipe is fixedly connected to the top of the material tube, a protective shell is fixedly connected to the top of the material tube, an air cavity is opened on the outside of the protective shell, and two sets of vibrating rings are fixedly connected to the outside of the material tube.

[0010] Preferably, the screw rod is rotatably connected to the material tube, and a trigger plate is fixedly connected to the outer side of the screw rod. One end of the trigger plate has an arc-shaped groove, and one end of the arc-shaped groove is set as an inclined surface, which connects the end face of the trigger plate and the arc-shaped groove.

[0011] Preferably, a first spring is provided inside the sleeve, a long rod is slidably connected to one end of the sleeve, and two sets of slip rings are fixedly connected to the outside of the long rod;

[0012] Two sets of slip rings are slidably connected to the outside of the material tube. One end of the first spring is fixedly connected to the inner wall of the sleeve, and the other end of the first spring is fixedly connected to the long rod. The other end of the long rod is spherical and contacts the end face of the trigger plate.

[0013] Preferably, a ball is fixedly connected to the outer side of the two sets of slip rings, and a rack is fixedly connected to the outer side of the two sets of slip rings. The rack is located at the top of one side of the two sets of slip rings, and the rack is slidably connected to the protective shell.

[0014] Preferably, the outer side of the sealing plate is provided with a ventilation groove, the inside of the sealing plate is rotatably connected to a rotating shaft, the bottom end of the rotating shaft is fixedly connected to a fan-shaped plate, the outer side of the rotating shaft is fixedly connected to a disc, and the rotating shaft is connected to the sealing plate through a torsion spring.

[0015] Preferably, a mounting hole is provided on the outer side of the disk, and a second spring is fixedly connected inside the mounting hole, with a toothed block fixedly connected to one end of the second spring;

[0016] The toothed block is slidably connected to one end of the mounting hole, and one side of the toothed block is set at an angle. The toothed block is set in multiple sets, and the multiple sets of toothed blocks mesh with the rack.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In the process of die-casting the structural components of the power distribution cabinet, firstly, the cylinder is started, and its action causes the moving mold to move along the guide rail and fit into the fixed mold; then, the exhaust valve is started to vent the gas between the two molds, and the connecting pipe is connected to the feeding end; finally, the motor is started, and the motor drives the screw rod to rotate in the material pipe, conveying the material from the connecting pipe to the fixed mold, thus completing the die casting.

[0019] 2. When the motor drives the screw to convey materials, the trigger plate rotates accordingly. When the arc groove of the trigger plate is aligned with the long rod, the long rod is released from the limit and slides under the action of the first spring force, which drives the slip ring to move along the outside of the material tube, so that the ball at the end of the slip ring hits the vibrating ring, causing the material tube to vibrate and separating the gas in the material.

[0020] As the trigger disc continues to rotate, the long rod, under the limit of the trigger disc, squeezes the first spring to reset, realizing the reciprocating sliding of the long rod and the continuous impact of the ball on the vibration ring, generating continuous intermittent vibration; this process ensures that there is no gas in the material, guarantees the quality of die-cast products, and improves the die-casting effect.

[0021] 3. When the slip ring drives the ball to strike the vibrating ring, it simultaneously pushes the rack to slide. Due to the angled design of one end of the tooth block and the elasticity of the second spring, the rack cannot initially drive the tooth block, preventing the disc from rotating. When the ball returns to its original position, the rack presses against the non-angled end of the tooth block, causing the disc to rotate, opening the venting groove, and releasing the separated gas. After the long rod fully returns to its original position, the rack separates from the tooth block, and the shaft returns to its original position under the action of the torsion spring. The sector plate closes the venting groove and the material pipe. Throughout the process, the equipment first vibrates to separate the gas, then opens the venting groove to exhaust the gas, ensuring complete gas discharge, reducing the opening of the material pipe, maintaining material purity, and improving the quality and effect of die-casting products.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1;

[0033] Please see Figures 1 to 4 This invention provides a technical solution: a high-strength, lightweight power distribution cabinet structural component die-casting device, comprising a base plate 1, a partition plate 2 fixedly connected to the top of the base plate 1, and a moving mold 3 fixedly connected to the top of the base plate 1. A fixed mold 4 is slidably connected to the top of the base plate 1. A material pipe 5 is provided at the top of the base plate 1. A motor 6 is adapted to be installed on the outside of the partition plate 2. A screw rod 7 is fixedly connected to the output end of the motor 6. The screw rod 7 is located inside the material pipe 5. A sleeve 8 is fixedly connected to the outside of the base plate 1. A sealing plate 9 is fixedly connected to the top of the material pipe 5.

[0034] Furthermore, a bracket 11 is fixedly connected to the bottom end of the base plate 1, and a guide rail 12 is provided at the top end of the base plate 1.

[0035] Among them, the bottom end of the moving mold 3 is provided with a guide block, which is located inside the guide rail 12.

[0036] Furthermore, a mounting plate 21 is fixedly connected to one end of the partition, and a fixing plate 22 is fixedly connected to the other end of the partition. The motor 6 is adapted to be installed on the outside of the fixing plate 22.

[0037] Furthermore, a cylinder 31 is fitted to the outer side of the mounting plate 21, and the output end of the cylinder 31 is fixedly connected to the outer side of the moving mold 3. An exhaust valve 41 is provided at the top of the fixed mold 4.

[0038] A support rod 51 is fixedly connected to the outside of the material pipe 5. The other end of the support rod 51 is fixedly connected to the top of the partition plate 2. A connecting pipe 52 is fixedly connected to the top of the material pipe 5. A protective shell 53 is fixedly connected to the top of the material pipe 5. An air cavity is opened on the outside of the protective shell 53. Two sets of vibrating rings 54 are fixedly connected to the outside of the material pipe 5.

[0039] When die casting is required for the structural components of the power distribution cabinet, the cylinder 31 is started first. The operation of the cylinder 31 drives the moving mold 3 to move along the guide rail 12 and causes the moving mold 3 to fit with the fixed mold 4. Then, the exhaust valve 41 is started to vent the gas between the moving mold 3 and the fixed mold 4. The connecting pipe 52 is connected to the feeding end. Finally, the motor 6 is started. The operation of the motor 6 will drive the screw rod 7 at the output end of the motor 6 to rotate inside the material pipe 5, and gradually transport the material falling from the connecting pipe 52 into the material pipe 5 into the fixed mold 4, and finally complete the die casting work.

[0040] In summary, during the die-casting process of the electrical distribution cabinet structural components, cylinder 31 is first activated, causing the moving mold 3 to move along guide rail 12 and fit into the fixed mold 4. Next, exhaust valve 41 is activated to vent the gas between the two molds, and connecting pipe 52 is connected to the material supply end. Finally, motor 6 is activated, driving screw 7 to rotate within material pipe 5, conveying material from connecting pipe 52 into the fixed mold 4, thus completing the die-casting process.

[0041] Example 2 improves upon Example 1 by refining the specific feeding process. For details, please refer to [link / reference]. Figure 5 , Figure 6 The screw rod 7 is rotatably connected to the material tube 5. A trigger plate 71 is fixedly connected to the outside of the screw rod 7. An arc groove 72 is opened at one end of the trigger plate 71. One end of the arc groove 72 is set as an inclined surface 73. The end face of the trigger plate 71 and the arc groove 72 are connected through the inclined surface 73.

[0042] Furthermore, a first spring 81 is provided inside the sleeve 8, and a long rod 82 is slidably connected to one end of the sleeve 8. Two sets of slip rings 83 are fixedly connected to the outside of the long rod 82.

[0043] Two sets of slip rings 83 are slidably connected to the outside of the material tube 5. One end of the first spring 81 is fixedly connected to the inner wall of the sleeve 8, and the other end of the first spring 81 is fixedly connected to the long rod 82. The other end of the long rod 82 is spherical and contacts the end face of the trigger plate 71.

[0044] Furthermore, a ball 831 is fixedly connected to the outer side of the two sets of slip rings 83, and a rack 832 is fixedly connected to the outer side of the two sets of slip rings 83. The rack 832 is located at the top of one side of the two sets of slip rings 83, and the rack 832 is slidably connected to the protective shell 53.

[0045] When the starting motor 6 drives the screw 7 to convey the material, it will also drive the trigger disc 71 fixed on the outside of the screw 7 to rotate. When the arc groove 72 on the outside of the trigger disc 71 rotates to one end of the long rod 82, the limit on the long rod 82 is released. Under the elasticity of the first spring 81 inside the sleeve 8, the long rod 82 will slide. The sliding long rod 82 will drive the slip ring 83 fixed on the outside of the long rod 82 to slide on the outside of the material tube 5, and cause the ball 831 at one end of the slip ring 83 to hit the vibrating ring 54, thereby causing the material tube 5 to vibrate. Under the action of vibration, the gas in the material will be separated from the material.

[0046] When the trigger disc 71 rotates to one end of the long rod 82, the long rod 82, under the limit of the trigger disc 71, compresses the first spring 81 to reset. Thus, as the trigger disc 71 rotates continuously, it causes the long rod 82 to slide back and forth, causing the ball 831 to continuously impact the vibrating ring 54, generating vibration. This achieves continuous intermittent vibration of the material, ensuring that the material does not contain gas, guaranteeing the quality of the final die-cast product, and further improving the die-casting effect.

[0047] By using the inclined surface 73 and the spherical design of one end of the long rod 82, it can be ensured that the contact between the trigger plate 71 and the long rod 82 can be smoothly transitioned during the rotation, thus ensuring the stability of the equipment operation.

[0048] In summary, when the motor 6 drives the screw rod 7 to convey materials, the trigger disc 71 rotates accordingly. When the arc groove 72 of the trigger disc 71 is aligned with the long rod 82, the long rod 82 is released from its limit and slides under the elastic force of the first spring 81, causing the slip ring 83 to move along the outside of the material tube 5. This causes the ball 831 at the end of the slip ring 83 to strike the vibrating ring 54, causing the material tube 5 to vibrate and separating the gas in the material.

[0049] As the trigger disc 71 continues to rotate, the long rod 82, limited by the trigger disc 71, presses the first spring 81 to reset, realizing the reciprocating sliding of the long rod 82 and the continuous impact of the ball 831 on the vibrating ring 54, generating continuous intermittent vibration. This process ensures that there is no gas in the material, guarantees the quality of the die-casting product, and improves the die-casting effect.

[0050] Example 3 is a further detailed description based on Example 2 above, which can be found in the following reference. Figure 7 , Figure 8 The specific method is as follows: a ventilation groove 91 is provided on the outer side of the sealing plate 9, a rotating shaft 92 is rotatably connected inside the sealing plate 9, a fan-shaped plate 93 is fixedly connected to the bottom end of the rotating shaft 92, a disc 94 is fixedly connected to the outer side of the rotating shaft 92, and the rotating shaft 92 is connected to the sealing plate 9 through a torsion spring.

[0051] Furthermore, a mounting hole 941 is provided on the outer side of the disc 94, and a second spring 942 is fixedly connected inside the mounting hole 941. A toothed block 943 is fixedly connected to one end of the second spring 942.

[0052] Among them, the toothed block 943 is slidably connected to one end of the mounting hole 941, and one side of the toothed block 943 is set at an angle. The toothed block 943 is set in multiple groups, and the multiple groups of toothed blocks 943 mesh with the rack 832.

[0053] When the slip ring 83 drives the ball 831 to strike the vibrating ring 54, it will simultaneously drive the rack 832 to slide. Because one end of the toothed block 943 is set at an angle, and the toothed block 943 is designed to slide elastically in conjunction with the second spring 942, the sliding rack 832 cannot drive the toothed block 943 at this time, and therefore cannot drive the disk 94 to rotate.

[0054] When the slip ring 83 drives the ball 831 to strike the vibrating ring 54 for reset, the rack 832 will squeeze the tooth block 943 without an angle during the reset process, thereby driving the disc 94 to rotate. The disc 94 drives the sector plate 93 to rotate through the rotating shaft 92, so that the venting groove 91 is opened, thereby completely removing the gas separated from the material.

[0055] After the long rod 82 is completely reset, the rack 832 separates from the tooth block 943. At this time, under the action of the torsion spring, the rotating shaft 92 will be reset, thereby sealing the vent groove 91 with the sector plate 93 and achieving the closure of the material tube 5.

[0056] Thus, during the overall operation of the equipment, the material is first vibrated to separate the gas in the material, and then the venting groove 91 is opened to completely discharge the gas. By first vibrating and separating the gas and then opening the venting groove, it is possible to ensure that the gas is completely discharged, and the opening of the material pipe 5 is reduced to ensure the purity of the material, guarantee the quality of the final die-cast product, and further improve the die-casting effect.

[0057] In summary, when the slip ring 83 drives the ball 831 to strike the vibrating ring 54, it simultaneously pushes the rack 832 to slide. Due to the angled design of one end of the tooth block 943 and the elasticity of the second spring 942, the rack 832 initially cannot drive the tooth block 943, preventing the disk 94 from rotating. When the ball 831 resets, the rack 832 presses against the non-angled end of the tooth block 943, causing the disk 94 to rotate, opening the venting groove 91, and expelling the separated gas. After the long rod 82 fully resets, the rack 832 separates from the tooth block 943, the shaft 92 resets under the action of the torsion spring, and the sector plate 93 closes the venting groove 91, sealing the material pipe 5. Throughout the process, the equipment first vibrates to separate the gas, then opens the venting groove to exhaust the gas, ensuring complete gas discharge, reducing the opening of the material pipe, maintaining material purity, and improving the quality and effect of die-casting products.

[0058] Example 4: This example is based on the overall operation of the above examples and can be referred to as follows. Figures 1 to 8 The specific method is as follows:

[0059] In the die-casting process for manufacturing electrical distribution cabinet structural components, cylinder 31 is first activated, causing the moving mold 3 to move along guide rail 12 and close with the fixed mold 4. Then, exhaust valve 41 is activated to purge gas between the molds, and connecting pipe 52 is connected to the material supply end. Finally, motor 6 is started, driving screw 7 to rotate inside material pipe 5, conveying material from connecting pipe 52 to the fixed mold 4, completing the die-casting process.

[0060] While the motor 6 drives the screw 7 to convey materials, the trigger disc 71 rotates accordingly. When the arc groove 72 of the trigger disc 71 is aligned with the long rod 82, the long rod 82 is released from its limit and slides under the action of the first spring 81, causing the slip ring 83 to move along the outside of the material tube 5, so that the ball 831 at the end of the slip ring 83 strikes the vibrating ring 54, causing the material tube 5 to vibrate, thereby separating the gas in the material.

[0061] As the trigger disc 71 continues to rotate, the long rod 82, under the limiting action of the trigger disc 71, squeezes the first spring 81 and resets, realizing the reciprocating motion of the long rod 82 and the continuous striking of the vibrating ring 54 by the ball 831, producing continuous intermittent vibration. This process ensures that the material is free of gas, thereby guaranteeing the quality of the die-cast product and improving the die-casting effect.

[0062] When the slip ring 83 drives the ball 831 to strike the vibrating ring 54, it also pushes the rack 832 to slide. Due to the angled design of the tooth block 943 and the elastic action of the second spring 942, the rack 832 initially cannot drive the tooth block 943, preventing the rotation of the disk 94. However, when the ball 831 resets, the rack 832 presses against the non-angled end of the tooth block 943, causing the disk 94 to rotate, opening the vent groove 91, and expelling the separated gas. After the long rod 82 is fully reset, the rack 832 separates from the tooth block 943, the rotating shaft 92 resets under the action of the torsion spring, and the sector plate 93 closes the vent groove 91, sealing the material pipe 5. Throughout the process, the equipment first separates the gas through vibration, then opens the vent groove to expel the gas, ensuring that the gas is completely discharged, reducing the opening of the material pipe, maintaining the purity of the material, ensuring the quality of the die-cast products, and further improving the die-casting effect.
