Elbow casting machine

Abstract

The present invention discloses an elbow casting machine, which relates to the technical field of water conservancy engineering, and includes a casting table, a support frame, and an alternating plate. The front and rear side walls of the two alternating plates are fixedly installed with support ring rods at equal distances, and the internal rotation of the support ring rods is connected with a separating and combining screw. The present invention improves the demoulding efficiency and the quality of the finished product through multiple designs when demoulding the elbow. On the one hand, when separating the two halves of the mold, the movable groove cooperates with the inclined protrusion so that the vibration rod continuously impacts the outside of the vibration mold to reduce the bonding strength. At the same time, the arc-shaped guide frame cooperates with the spiral guide groove to allow the vibration rod to move and vibrate along the outer surface of the mold, evenly covering and avoiding local stress concentration. On the other hand, the trigger rod cooperates with the second support block to spray the molded elbow with a release agent at the initial stage of separation to ensure utilization efficiency. The subsequent vibration function also promotes the release agent to penetrate the gap, reducing the difficulty of demoulding and meeting the production needs of water conservancy engineering elbows.

Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, in particular to an elbow casting machine. Background Art

[0002] Water conservancy projects involve the supply of domestic and industrial water, as well as sewage treatment and discharge. In water supply pipes, elbows are used to adjust the direction of water flow and optimize the layout of the pipe network. In drainage systems, corrosion-resistant elbows (such as ceramic composite materials) can cope with chemical substances in sewage. In addition, hydropower generation is an important part of water conservancy projects, converting water energy into electrical energy. Therefore, high-strength elbows are required in high-pressure water pipelines to withstand the impact of water flow and pressure changes. At the same time, flood control projects are one of the basic functions of water conservancy projects. In drainage pipes and flood discharge channels, large-diameter elbows are used to adjust the flow path and reduce turbulent damage to the structure. Therefore, water conservancy projects generally require large quantities of pipe elbows with multiple specifications. The efficient production mode of elbow casting machines can meet this demand.

[0003] For example, the Chinese patent, publication number: CN118699290B, patent name: A elbow casting machine. It can be seen that this patented technology uses the design of four sets of half-side elbow molds to enable the elbow after casting to be automatically ejected by separating the two half molds, and can be collected without removing the mold.

[0004] However, the above patents still have the following problems in the implementation process:

[0005] For example, it uses two half-side elbow molds to separate so that the formed elbow falls off automatically. However, in the actual separation process, the metal or non-metallic material of the elbow will shrink during the cooling stage during the casting process. The shrinkage rates of different parts may vary due to temperature gradients and material anisotropy. If the contact area between the elbow and a certain half-side mold forms a local "vacuum adsorption effect" due to the difference in shrinkage rate, the degree of fit between the formed elbow and the two half-side molds will be inconsistent, which may easily cause the formed elbow to stick to one of the half-side molds and fail to achieve synchronous separation and falling. Alternatively, the elbow may fall after moving a certain distance with one of the half-side molds, and at this time, it will not be able to fall accurately to the collection position, so there is a problem of poor production efficiency due to unstable demolding.

Two half-side molds 6 are arranged between two adjacent support ring rods 4 on the same side.

[0030] The outer wall of the half mold 6 is provided with a separation and dispersion component 7.

[0031] Furthermore, the separation and dispersion component 7 includes a first support block 701, the inner walls of the two first support blocks 701 are threadedly connected to the outer wall of the separating and combining screw 5 away from the alternating plate 3, one end of the two first support blocks 701 is respectively fixedly connected to the outer wall of the two half-side molds 6 away from the alternating plate 3, the outer walls of the two half-side molds 6 facing the alternating plate 3 are fixedly connected with a second support block 702, the inner walls of the two second support blocks 702 are threadedly connected to the outer wall of the separating and combining screw 5 close to the alternating plate 3, the interior of the two second support blocks 702 are slidably provided with a support cross bar 703, and the two ends of the support cross bar 703 are respectively fixed to the inner wall between the two adjacent support ring rods 4 on the same side, the outer wall of the side away from the two second support blocks 702 is fixedly connected with a slide 704, and the inner wall of the slide 704 is slidably connected to the outer wall of the support cross bar 703.

[0032] Furthermore, when producing elbows, the two alternating plates 3 are respectively arranged at the loading station and the cooling station, and can rotate to change the stations. First, the molten metal or other alloy is injected into the two merged half-molds 6 on the alternating plate 3 located at the loading station. After the injection is completed, the two alternating plates 3 are driven by a driving device to exchange positions, and the several merged half-molds 6 that have been injected are transferred to the cooling station for rapid molding. During the molding process, the several half-molds 6 on the other alternating plate 3 to be loaded can be loaded, so that the loading and cooling are carried out simultaneously.

[0033] More specifically, in the embodiment, after the elbows in the two merged half molds 6 are formed, the inner walls of the two first support blocks 701 can be threadedly connected to the outer wall of the separating and combining screw 5 away from the alternating plate 3, and one end of the two first support blocks 701 is fixedly connected to the outer wall of the two half molds 6 away from the alternating plate 3, and the outer wall of the two half molds 6 facing the alternating plate 3 is fixedly connected with the second support block 702, and the inner walls of the two second support blocks 702 are threadedly connected to the outer wall of the separating and combining screw 5 close to the alternating plate 3, so that the two half molds 6 can be driven to separate by the rotation of the separating and combining screw 5.

[0034] Then, during the separation process of the two half-side molds 6, support cross bars 703 are slidably provided inside the two second support blocks 702, and the two ends of the support cross bars 703 are respectively fixed to the inner wall between the two adjacent support ring bars 4 on the same side, and the outer wall of the side where the two second support blocks 702 are away from each other is fixedly connected with a slide 704, and the inner wall of the slide 704 is slidably connected to the outer wall of the support cross bar 703, so that when the two second support blocks 702 are separated, the two slides 704 can be synchronously driven to move away.

[0035] Then, the rotating rod 705 is rotatably connected to one end of the two slide cylinders 704 that are away from each other, and the inner wall of the rotating rod 705 is rotatably connected to the outer wall of the supporting cross bar 703. The outer wall of the supporting cross bar 703 is symmetrically provided with a spiral guide groove 706, and the inner wall of the rotating rod 705 is fixedly connected with a ball 707 corresponding to the spiral guide groove 706. The outer wall of the ball 707 fits and slides with the inner wall of the spiral guide groove 706. Therefore, when the two rotating rods 705 move away from each other, the spiral guide groove 706 and the ball 707 can cooperate with each other to make the rotating rods 705 continue to rotate a certain angle in the process of moving away from each other.

[0036] Then, the outer wall of the side where the two arc-shaped guide frames 708 are close to each other is fixedly connected with a support column 709, and one end of the two support columns 709 is fixedly connected to the outer wall of the side where the two half-side molds 6 are away from each other. The inner wall of the arc-shaped guide frame 708 is fitted and slidably connected with a vibration rod 710, and the outer wall of the vibration rod 710 is provided with a movable groove 711. The inner wall of the arc-shaped guide frame 708 is symmetrically fixedly connected with a limiting arc bar 712 corresponding to the movable groove 711. The outer wall of the side where the two limiting arc bars 712 are close to each other is fitted and slid with the inner wall of the movable groove 711, and the rotation rod 705 is connected. The outer wall on the near side corresponds to the vibration rod 710 and is provided with a sliding groove 713, and the outer wall of the vibration rod 710 fits and slides with the inner wall of the sliding groove 713, and the ends of the two vibration rods 710 that are away from each other are fixedly connected to a spring 1 714, and the ends of the two springs 1 714 that are away from each other are fixedly connected to a connecting ring 715, and the ends of the two connecting rings 715 that are away from each other fit and slide with the inner wall of the sliding groove 713, so that under normal circumstances, the elastic force of the spring 1 714 drives the ends of the two vibration rods 710 that are close to each other to fit and squeeze with the ends of the two half-side molds 6 that are away from each other.

[0037] When the lever 705 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever 706 is in a state of rotation and the lever After the movable groove 711 of the vibration rod 710 passes over a certain inclined protrusion 716, it can be reset by the rapid rebound of spring 1 714, and then drive the two vibration rods 710 to approach each other and impact, so that the vibration rod 710 can continuously impact and vibrate the outside of the two half-side molds 6, thereby reducing the bonding strength between the half-side mold 6 and the formed elbow during the separation process. At the same time, through the cooperation of the arc guide frame 708 and the spiral guide groove 706, the vibration rod 710 can move and vibrate along the outside of the half-side mold 6, not only evenly covering different areas of the outer surface of the half-side mold 6, but also avoiding the problem of local stress concentration caused by fixed knocking at a certain position, which is beneficial to improving the demolding efficiency and finished product quality of this molding machine, and meeting the elbow production needs of water conservancy projects.

[0038] Embodiment 2: Based on the above embodiment, auxiliary dropping components 8 are provided inside the front and rear sides of the alternating plate 3 corresponding to the separation and dispersion components 7 .

[0039] Furthermore, the auxiliary falling component 8 includes a piston 802, and cavities 801 are equidistantly provided inside the front and rear sides of the alternating plate 3. The outer wall of the piston 802 slides in contact with the inner wall of the cavity 801. The piston 802 on the same side is fixedly connected to a trigger rod 803 on one end face facing the second support block 702, and the other end of the trigger rod 803 extends through the interior of the alternating plate 3 to the outside of the alternating plate 3. The piston 802 on the same side is fixedly connected to a spring 2 804 on one end face away from the second support block 702, and the other end of the spring 2 804 is fixedly connected to the inner wall of the cavity 801. The trigger rod 803 forms a telescopic structure through the piston 802 and the spring 2 804. The end of the trigger rod 803 facing the second support block 702 is in an inclined state, and the end of the trigger rod 803 facing the second support block 702 is squeezed by the spring 2 804 on the same side of the outer wall of the two second support blocks 702.

[0040] More specifically, in the embodiment, when the elbow is demoulded, cavities 801 are opened at equal distances inside the front and rear sides of the alternating plate 3, and the outer wall of the piston 802 slides in contact with the inner wall of the cavity 801. The piston 802 on the same side is fixedly connected to a trigger rod 803 on one end facing the second support block 702, and the other end of the trigger rod 803 extends through the interior of the alternating plate 3 to the outside of the alternating plate 3. The piston 802 on the same side is fixedly connected to a spring 2 804 on one end away from the second support block 702, and the other end of the spring 2 804 is fixedly connected to the spring 2 804. Fixedly connected to the inner wall of the cavity 801, the trigger rod 803 forms a telescopic structure through the piston 802 and the spring 2 804. The end of the trigger rod 803 facing the second support block 702 is in a truncated cone shape, and the end of the trigger rod 803 facing the second support block 702 is squeezed against the outer wall of the same side of the two second support blocks 702 through the spring 2 804. Therefore, when the two half-side molds 6 are in a merged state, the truncated cone end of the trigger rod 803 will use the elastic force of the spring 2 804 to push against the middle position of the outer wall of the same side of the two second support blocks 702.

[0041] When the two half molds 6 are separated and demoulded, the two second support blocks 702 will be separated synchronously, so that the trigger rod 803 can be pushed out by the spring 2 804, so that the release agent in the cavity 801 can be squeezed and pushed by the piston 802. At this time, inclined spray holes 805 are symmetrically opened on the front and rear outer walls of the alternating plate 3 corresponding to the cavity 801 at equal distances, and the inner walls of the inclined spray holes 805 are connected to the inner wall of the cavity 801, and the inner walls of the two inclined spray holes 805 are inclined toward the space between the outer walls of the same side of the two second support blocks 702. The mold release agent is sprayed on the leaked molded elbow at the initial stage of separation, which is conducive to the mold release agent sprayed on the surface of the elbow to cover the surface between the two separated half-molds 6 and the molded elbow respectively, ensuring the utilization efficiency of the mold release agent. At the same time, the subsequent vibration function can promote the mold release agent to penetrate into the gap between the molded elbow and the half-mold 6, further reducing the difficulty of subsequent demoulding and achieving an efficient demoulding effect, which is conducive to improving the demoulding efficiency and finished product quality of the molding machine and meeting the elbow production needs of water conservancy projects.

[0042] Then, when the demolding is completed, the two half molds 6 begin to merge again, so that the conical end of the ejected trigger rod 803 can be squeezed and the trigger rod 803 is pressed back into the cavity 801. At this time, a liquid inlet pipe 806 is fixedly connected to the inner wall of the cavity 801, and a liquid storage cylinder 9 is installed at the top of the two alternating plates 3 corresponding to the liquid inlet pipe 806, and the other end of the liquid inlet pipe 806 is fixedly installed on the outer wall of the liquid storage cylinder 9, so that the release agent in the liquid storage cylinder 9 can be re-sucked and replenished into the cavity 801 through the reset movement of the piston 802 using the liquid inlet pipe 806 for next use.

[0043] Then, one-way valves are installed in the liquid inlet pipe 806 and the inclined spray hole 805 respectively, thereby realizing one-way communication, so that when the trigger rod 803 can be pushed out, the release agent is pushed out by the piston 802, and the release agent is sucked and replenished when the piston 802 is reset.

[0044] Working principle: After the elbow is formed in the two merged half-side molds 6, the two half-side molds 6 are first separated by the rotation of the separating and combining screw 5. When the two second support blocks 702 are separated, the two slide cylinders 704 can be synchronously driven to move away. When the two rotation rods 705 move away from each other, the spiral guide groove 706 and the ball 707 can cooperate to make the rotation rods 705 continue to rotate a certain angle in the process of moving away from each other, thereby synchronously driving the vibration rod 710 to move along the inner wall of the arc-shaped guide frame 708.

[0045] During the movement of the vibration rod 710, the inner wall of the movable groove 711 of the vibration rod 710 can be contacted and squeezed by the inclined protrusion 716, so that the two vibration rods 710 move away from each other and squeeze the spring 1 714. When the movable groove 711 of the vibration rod 710 passes over a certain inclined protrusion 716, it can be reset by the rapid rebound of the spring 1 714, and then drive the two vibration rods 710 to approach each other and impact, so that the vibration rod 710 can continuously impact and vibrate the outside of the two half-side molds 6, thereby reducing the bonding strength between the half-side mold 6 and the forming elbow during the separation process. At the same time, through the cooperation of the arc guide frame 708 and the spiral guide groove 706, the vibration rod 710 can move and vibrate along the outside of the half-side mold 6, not only evenly covering different areas of the outer surface of the half-side mold 6, but also avoiding the problem of local stress concentration caused by fixed knocking at a certain position, which is beneficial to improving the demolding efficiency and finished product quality of this molding machine.

[0046] Then, when the two half-molds 6 are in a merged state, the conical end of the trigger rod 803 will use the elastic force of the second spring 804 to push against the middle position of the outer wall of the same side of the two second support blocks 702. When the two half-molds 6 are separated and demolded, the two second support blocks 702 will be separated synchronously, so that the trigger rod 803 can be pushed out by the second spring 804, so that the piston 802 can be used to squeeze and push the release agent in the cavity 801, so that the release agent is sprayed out from the inclined spray hole 805, and the release agent can be sprayed on the leaked molding elbow immediately at the initial stage of separation, which is conducive to the release agent sprayed on the surface of the elbow to cover the surface between the two separated half-molds 6 and the molding elbow respectively. At the same time, the subsequent vibration function can promote the release agent to penetrate into the gap between the molding elbow and the half-mold 6, further reducing the difficulty of subsequent demolding and achieving an efficient demolding effect.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
