The top two connection ports of the feeding channel are located inside the outlet of the discharge connection port channel. The bottom of the feeding channel is connected to the material diversion pipe. The outlet of the discharge connection port channel is slidably connected to the inside of the sliding connecting plate. When the hydraulic telescopic rod moves the telescopic connecting block, it can also move the feeding channel inside the telescopic connecting block synchronously. When the feeding channel moves, it can also move the sliding connecting plate along the outlet of the discharge connection channel. When the feeding channel moves, it can connect with the outlet of the discharge connection channel in the direction of movement. When the feeding channel is connected with the outlet of the discharge connection channel, the discharge connection can inject casting raw materials into the interior of the movable mold block and the fixed mold block through the feeding channel and the material diversion pipe.

[0010] Preferably, a partition block is provided in the middle of the material diversion pipe, and the connection points of the material diversion pipe and the feeding channel are located on both sides of the partition block. Both sides of the material diversion pipe pass through the interior of the movable mold assembly. When the feed channel is connected to the channel outlet on one side of the discharge connection port, the casting raw material can be guided into the material diversion pipe on the corresponding side, and the casting raw material can be injected into the movable mold block and the fixed mold block on one side through the material diversion pipe.

[0011] Preferably, the workpiece demolding mechanism includes a sliding connecting rod, which is fixedly installed on the top of the support base.

[0015] A method for manufacturing a main and auxiliary valve plate regulating and guiding control valve uses the valve body casting equipment described above.

[0016] Compared with the prior art, the present invention provides a valve body casting equipment and a method for manufacturing a main and auxiliary valve plate regulating and guiding control valve, which has the following beneficial effects: 1. In this type of valve body casting equipment, when the movable mold block moves towards the fixed mold block, the limiting spring is compressed. After casting is completed, the movable mold block moves in the opposite direction. At this time, the limiting spring rebounds, causing the stop connecting rod and the demolding stop to move synchronously with the movable mold block. After the limiting spring rebounds, the movable mold block continues to move. At this time, the limiting connecting plate is supported by the spring on the other side and remains stationary. The demolding stop gradually separates from the movable mold block. During the gradual separation of the demolding stop from the movable mold block, the demolding stop can separate the cast workpiece from the demolding stop. During the repeated movement of the movable mold block, the limiting spring can limit the movement state of the stop connecting rod through elastic support. The connection state between the demolding stop and the movable mold block is adjusted by the movement state of the stop connecting rod, which enables the movable mold block to complete the demolding separation from the workpiece during the movement, thereby ensuring the production efficiency of the workpiece.

[0017] 2. This valve body casting equipment allows the movable mold block to connect with a fixed mold block on one side to form a casting mold when the movable mold block moves and contacts it. At this time, the discharge port can inject casting raw materials into the movable mold block and the fixed mold block through the feed channel and the material diversion pipe. After the workpiece is formed, the movable mold block moves to the other side and connects with the fixed mold block on the other side. When the movable mold block connects with the fixed mold block on the other side, the feed channel can connect with the outlet channel on the other side of the discharge port, and casting raw materials are injected into the movable mold block and the fixed mold block on one side through the material diversion pipe to continue the casting operation. By cyclically moving the movable mold block laterally and connecting with the fixed mold blocks on both sides for casting, the fixed mold block has a cooling time after casting is completed, thus ensuring the forming quality and forming efficiency of the workpiece.

[0020] 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.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a valve body casting equipment and a method for manufacturing a main and auxiliary valve plate regulating and guiding control valve. Example

[0022] Please see Figure 1 - Figure 12A valve body casting equipment includes a support base 1, a support mounting frame 2 installed on the top of the support base 1, a connection port mounting frame 3 installed on the outside of the support mounting frame 2, a discharge connection port 4 installed inside the connection port mounting frame 3, a fixed mold block 5 installed on the top of the support base 1, a movable mold structure 6 installed inside the support mounting frame 2, a workpiece demolding mechanism 7 installed inside the movable mold structure 6, and a discharge guide plate 8 installed on the top of the support base 1. The bottom of the discharge port 4 is slidably connected to the top of the movable mold structure 6. The discharge port 4 has two channels inside. The upper part of the workpiece demolding mechanism 7 is slidably connected to the inside of the movable mold structure 6. The bottom of the workpiece demolding mechanism 7 is connected to the support base 1. The movable mold structure 6 can move laterally inside the support mounting frame 2 and connect with the fixed mold blocks 5 on both sides. The discharge port 4 can connect with the external feed port and add casting raw materials into the movable mold structure 6 and the fixed mold blocks 5. When the movable mold structure 6 moves, it can connect with the two channels inside the discharge port 4. When the movable mold structure 6 moves, it can drive the workpiece demolding mechanism 7 to move. When the workpiece demolding mechanism 7 moves, it can demold the cast workpiece.

[0023] During operation, the discharge port 4 can connect to the external inlet, causing the movable mold structure 6 to move to one side and assemble with the corresponding fixed mold block 5 to form a mold. During the movement of the movable mold structure 6, its top can slide relative to the discharge port 4 and connect to the channel outlet on the corresponding side of the discharge port 4. Then, the external discharge port injects casting material into the interior of the movable mold structure 6 through the discharge port 4. The casting material entering the movable mold structure 6 flows into the casting mold formed by the movable mold structure 6 and the fixed mold block 5, and waits for the internal workpiece to form. When the workpiece is formed inside the mold formed by the movable mold structure 6 and the fixed mold block 5, the movable mold structure 6 moves in the opposite direction, contacting the workpiece during its movement. With a large area, the moving mold structure 6 can move synchronously with the formed workpiece. During the movement of the moving mold structure 6, the workpiece demolding mechanism 7 can actively demold the workpiece, allowing the formed workpiece to fall onto the discharge guide plate 8. Then, the moving mold structure 6 continues to move and assembles with the fixed mold block 5 on the other side to form a mold. During the movement of the moving mold structure 6, the top of the moving mold structure 6 can connect with the channel outlet on the other side of the discharge connection port 4, thereby injecting casting raw materials into the other side of the interior of the moving mold structure 6. The casting operation is repeated in this way. The cyclic casting operation is carried out by the repeated movement of the moving mold structure 6 inside the support mounting frame 2. In addition, during the movement of the moving mold structure 6, the formed workpiece can also be demolded by the workpiece demolding mechanism 7, thus enabling a good working cycle. Example

[0024] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The movable mold structure 6 includes a telescopic mounting frame 61, which is fixedly installed inside the support mounting frame 2. A hydraulic telescopic rod 62 is installed on the outside of the telescopic mounting frame 61. A telescopic connecting block 63 is connected to the drive end of the hydraulic telescopic rod 62. A movable mold assembly block 64 is connected to the bottom of the telescopic connecting block 63. A feeding channel 65 is installed inside the telescopic connecting block 63. A sliding connecting plate 66 is connected to the top of the feeding channel 65. A material diversion pipe 67 is installed inside the movable mold assembly block 64.

[0025] The movable mold assembly 64 is connected to the hydraulic telescopic rod 62 via the telescopic connecting block 63 at the top. Both sides of the movable mold assembly 64 can be spliced ​​with the fixed mold assemblies 5 on both sides. When the hydraulic telescopic rod 62 extends or retracts, it can drive the movable mold assembly 64 to move synchronously through the telescopic connecting block 63. When the movable mold assembly 64 moves, it can be spliced ​​with the fixed mold assemblies 5 on both sides to form a mold cavity.

[0026] The feeding channel 65 inside the telescopic connecting block 63 is also provided with two channels. The two connection ports at the top of the feeding channel 65 are located inside the outlet of the discharge connection port 4 channel. The bottom of the feeding channel 65 is connected to the material diversion pipe 67. The outlet of the discharge connection port 4 channel is slidably connected to the inside of the sliding connecting plate 66. When the hydraulic telescopic rod 62 moves the telescopic connecting block 63, it can move the feeding channel 65 inside the telescopic connecting block 63 synchronously. When the feeding channel 65 moves, it can move the sliding connecting plate 66 along the outlet of the discharge connection port 4. When the feeding channel 65 moves, it can connect with the outlet of the discharge connection port 4 in the direction of movement. When the feeding channel 65 is connected with the outlet of the discharge connection port 4, the discharge connection port 4 can inject casting raw materials into the interior of the movable mold assembly 64 and the fixed mold assembly 5 through the feeding channel 65 and the material diversion pipe 67.

[0027] A partition block is provided in the middle of the material diversion pipe 67. The connection points of the material diversion pipe 67 and the feed channel 65 are located on both sides of the partition block. Both sides of the material diversion pipe 67 pass through the interior of the movable mold assembly 64. When the feed channel 65 is connected to the channel outlet on one side of the discharge connection port 4, it can guide the casting raw material into the material diversion pipe 67 on the corresponding side, and inject the casting raw material into the interior of the movable mold block 64 and the fixed mold block 5 on one side through the material diversion pipe 67.

[0028] During operation, the extension and retraction of the hydraulic telescopic rod 62 can drive the telescopic connecting block 63 to move within the support mounting frame 2. When the telescopic connecting block 63 moves, it can drive the movable mold assembly 64 to move synchronously. When the movable mold assembly 64 moves, it can contact the fixed mold assembly 5. When the movable mold assembly 64 contacts the fixed mold assembly 5, it can be assembled with the fixed mold assembly 5 to form a casting mold. Furthermore, when the telescopic connecting block 63 moves, it can drive the feeding channel 65 to move synchronously. When the feeding channel 65 moves, it can drive the sliding connecting plate 66 to move along the outlet of the discharge connection port 4. When the feeding channel 65 moves, it can connect with the outlet of the discharge connection port 4 in the direction of movement. When the feeding channel 65 connects with the outlet of the discharge connection port 4, the discharge connection port 4 can inject casting raw materials into the movable mold assembly 64 and the fixed mold assembly 5 through the feeding channel 65 and the material diversion pipe 67. After the workpiece inside the movable mold assembly 64 and the fixed mold assembly 5 is formed, the hydraulic telescopic rod 62 drives the movable mold... The movable mold block 64 moves in the opposite direction, and there is a certain amount of space between the interior of the movable mold block 64 and the workpiece demolding mechanism 7. After the movable mold block 64 moves a certain distance, it can drive the workpiece demolding mechanism 7 to move synchronously. When the movable mold block 64 moves and the workpiece demolding mechanism 7 remains stationary, the workpiece demolding mechanism 7 can demold the workpiece on the movable mold block 64. Then the movable mold block 64 continues to move and connects with the fixed mold block 5 on the other side. When the movable mold block 64 connects with the fixed mold block 5 on the other side, the feeding channel 65 can connect with the channel outlet on the other side of the discharge connection port 4. The casting raw materials are injected into the interior of the movable mold block 64 and the fixed mold block 5 on one side through the material diversion pipe 67, so as to continue the casting operation. By moving the movable mold block 64 laterally and connecting with the fixed mold blocks 5 on both sides to carry out the casting operation, the fixed mold block 5 can have a cooling time after casting is completed, thereby ensuring the molding quality and molding efficiency of the workpiece. Example

[0029] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The workpiece demolding mechanism 7 includes a sliding connecting rod 71, which is fixedly installed on the top of the support base 1. Limiting springs 72 are installed at both ends of the inner side of the sliding connecting rod 71. The movable ends of the limiting springs 72 are connected to limiting support plates 73. A limiting connecting plate 74 is slidably installed on the outside of the sliding connecting rod 71. A stop connecting rod 75 is connected to the top of the limiting connecting plate 74. A demolding stop 76 is connected to the outside of the stop connecting rod 75.

[0030] The limiting support plate 73 is slidably installed on the outside of the sliding connecting rod 71. The outside of the limiting support plate 73 is connected to the outside of the sliding connecting rod 71 through the limiting spring 72. The outside of the limiting support plate 73 is in contact with the outside of the limiting connecting plate 74. When the limiting connecting plate 74 moves to one side, it can drive the limiting spring 72 on one side to compress through the limiting support plate 73.

[0031] The movable mold assembly 64 has a sliding groove inside for the movement of the limiting connecting plate 74. When the movable mold assembly 64 moves, it can first slide along the outside of the limiting connecting plate 74 and then drive the limiting connecting plate 74 to move synchronously.

[0032] The length of the stop connecting rod 75 is greater than the width of the movable mold assembly 64. The stop connecting rod 75 and the movable mold assembly 64 are slidably connected. When the movable mold assembly 64 moves, it can drive the stop connecting rod 75 to move after contacting the demolding stop 76. When the stop connecting rod 75 moves, it can drive the limiting connecting plate 74 to move synchronously. When the movable mold assembly 64 moves and separates from the demolding stop 76, the cast workpiece can be demolded through the demolding stop 76.

[0033] During operation, the movable mold assembly 64 moves laterally in a cyclic manner to perform casting operations. When the movable mold assembly 64 moves to one side, it first slides into contact with the stop connecting rod 75. At this time, the stop connecting rod 75 is released from the limit support plate 73 through the limit connecting plate 74. Supported by the limit spring 72, the stop connecting rod 75 remains stationary. As the movable mold assembly 64 continues to move, it can contact the demolding stop 76. After the movable mold assembly 64 contacts the demolding stop 76, the demolding stop 76 can drive the stop connecting rod 75 to move. The movement of the stop connecting rod 75 can cause the limit spring 72 on the corresponding side to compress through the contact between the limit connecting plate 74 and the limit support plate 73. Then, the movable mold assembly 64 performs casting operations. After casting is completed, the movable mold assembly 64 moves in the opposite direction. At this time, the limit spring 72 rebounds, causing the stop connecting rod 75 and the demolding stop 76 to move synchronously with the movable mold assembly 64. After the limit spring 72 returns to its original position, the movable mold block 64 continues to move. At this time, the limit connecting plate 74 remains stationary due to the support of the spring on the other side. The demolding block 76 gradually separates from the movable mold block 64. During the gradual separation of the demolding block 76 from the movable mold block 64, the demolding block 76 can separate the cast workpiece from the demolding block 76. As the movable mold block 64 continues to move, it can contact the demolding block 76 on the other side and drive the demolding block 76 to move to the other side to perform the casting operation again. During the repeated movement of the movable mold block 64, the limit spring 72 can limit the movement state of the stop connecting rod 75 through the elastic support. The movement state of the stop connecting rod 75 can adjust the connection state between the demolding block 76 and the movable mold block 64, so that the movable mold block 64 can complete the demolding separation from the workpiece during the movement, thereby ensuring the production efficiency of the workpiece. Example

[0034] A positioning method for machining a brake assembly, using a valve body casting apparatus as described in Examples 1 to 3, includes the following steps: When working, first connect the discharge port 4 to the external discharge port; When the movable mold structure 6 moves to one side, it can be spliced ​​with the fixed mold block 5 on the corresponding side to form a casting mold; The external discharge port can inject casting raw materials into the interior of the movable mold structure 6 through the discharge connection port 4; After the valve body is formed inside the movable mold structure 6 and the fixed mold block 5, the movable mold structure 6 moves to the other side. During the process of the moving mold structure 6 moving to the other side, the workpiece demolding mechanism 7 can demold the casting mold on the moving mold structure 6. After the movable mold structure 6 comes into contact with the fixed mold block 5 on the other side, the valve body can be cast again.
