Description

Technical Field

[0001] The invention relates to the field of casting moulds, in particular to a nine-port valve body casting mould. Background Art

[0002] Casting dies are used to rapidly press liquid or semi-liquid metal into the mold cavity under high pressure, where it solidifies and forms. These dies offer advantages such as high production efficiency, precise casting dimensions, and excellent surface quality, making them widely used in industries such as automobiles, motorcycles, and electronics.

[0003] Reference Figure 9 This is a schematic diagram of a nine-mouth valve body product. During casting, a larger gate may be designed to ensure smooth filling of the liquid metal and avoid insufficient pouring or cold shut defects. However, the large gate is difficult to cut directly and requires precise processing of the large gate through CNC milling and turning technology. However, the product after casting is then processed by CNC milling and turning, which makes the production efficiency of the nine-mouth valve body low. Summary of the Invention

[0004] In order to improve the production efficiency of a nine-port valve body, the present application provides a nine-port valve body casting mold.

[0005] The nine-port valve body casting mold provided in this application adopts the following technical solution: A nine-mouth valve body casting mold includes a fixed mold plate and a movable mold plate, and the movable mold plate is slidably connected to a plurality of side withdrawal blocks with product molding surfaces, and also includes a gate reduction component, and the gate reduction component is used to reduce the gate after casting is completed. The gate reduction component includes multiple sliding blocks with molding surfaces and a driving component, and some of the side withdrawal blocks are provided with multiple gate runners, and the multiple sliding blocks respectively correspond to the multiple gate runners. The multiple sliding blocks are respectively slidably connected to the side withdrawal blocks with the gate runners, and the driving component is used to drive the movement of the sliding blocks and the side withdrawal blocks. When the casting mold completes the casting operation, the multiple sliding blocks respectively move toward one side of the gate runner until they abut on the fixed mold to divide the gate runner.

[0006] By adopting the above technical solution and providing a gate reduction assembly, the gate runner can be segmented and reduced after casting is completed. The gate runners are provided on some side withdrawal blocks, to which the sliding blocks are slidably connected. The driving assembly controls the movement of the sliding blocks, which ultimately abut the fixed mold to segment the gate runners. This reduces the gate size of the molded product, eliminating the need for CNC milling of the gate, allowing direct shearing of the gate, thereby improving the production efficiency of the nine-gate valve body.

[0007] Preferably, a connecting rod is slidably connected to the side withdrawal block, and several sliding blocks on the same side withdrawal block are fixedly connected to the connecting rod at the same time, and the driving assembly is used to drive the sliding of the connecting rod.

[0008] By adopting the above technical solution, the driving component synchronously drives the movement of multiple sliding blocks by controlling the sliding of the connecting rod. The multiple sliding blocks are integrated through the connecting rod to avoid driving each sliding block individually, reducing the complexity and cost of the driving component. The connecting rod can ensure that the sliding blocks on the same side of the withdrawal block move synchronously, avoiding the asynchronous movement caused by individual driving, and ensuring the accuracy and stability of the gate reduction.

[0009] Preferably, the driving assembly includes a hydraulic cylinder and a limit assembly, the side drawer block is provided with a first inclined rail, the connecting rod is provided with a second inclined rail, the connecting rod can be moved to the first inclined rail and the second inclined rail to be connected, the hydraulic cylinder is fixedly connected to the movable template, and a slider is provided at one end of the piston rod of the hydraulic cylinder, and the slider can be slidably connected to the first inclined rail or the second inclined rail, and the limit assembly is used to limit the sliding of the connecting rod and the side drawer block respectively. During the mold closing process, the sliding block is located on the first inclined rail and the second inclined rail at the same time, and the limit assembly limits the position of the sliding block on the side drawer block. When casting is completed, the sliding block moves to the second inclined rail, and the limit assembly limits the position of the side drawer block on the movable mold.

[0010] By adopting the above technical solution, a hydraulic cylinder drives the slider to slide on two inclined rails, which cooperate with the limit assembly to achieve the sequential movement of the connecting rod and the side withdrawal block. When the mold is closed, the slider is located on both the first and second inclined rails. The limit assembly limits the position of the slide block on the side withdrawal block, allowing the connecting rod and the side withdrawal block to move synchronously. After casting is completed, the slider moves to the second inclined rail, the limit assembly fixes the side withdrawal block, and the hydraulic cylinder continues to move to drive the connecting rod and the slide block to complete the gate reduction.

[0011] Preferably, the moving direction of the piston rod is inclined relative to the moving direction of the side draw block.

[0012] By adopting the above technical solution, the moving direction of the piston rod is inclined relative to the moving direction of the side draw block, so that the slider can slide along, so that the slider is located on the first inclined rail and the second inclined rail at the same time when the mold is closed, and the slider moves to the second inclined rail after casting is completed.

[0013] Preferably, the limit assembly includes a limit rod, a first limit groove is provided on the fixed mold, a second limit groove is provided on the side wall of the connecting rod, and the limit rod is slidably connected to the side draw block along a sliding direction perpendicular to the sliding direction of the connecting rod. The two ends of the limit rod in the length direction can respectively cooperate with the first limit groove and the second limit groove. During the casting process, one end of the limit rod moves to cooperate with the second limit groove, and when the casting is completed, the other end of the limit rod moves to cooperate with the first limit groove.

[0014] By adopting the above technical solution, during casting, the limiting rod cooperates with the second limiting groove to lock the connecting rod, preventing the sliding block from moving and affecting the stability of the gate runner. After casting, the limiting rod cooperates with the first limiting groove to lock the side withdrawal block, ensuring that the side withdrawal block is stationary when the hydraulic cylinder drives the connecting rod.

[0015] Preferably, the driving assembly also includes a spring, which is installed on the limit rod. The spring always drives the limit rod to move toward one side of the connecting rod. A guide groove is also provided on the side wall of the connecting rod. The guide groove is connected to the second limit groove. The guide groove gradually becomes closer to the side wall of the connecting rod from the side close to the second limit groove to the side away from the second limit groove. When the casting is completed, the limit rod moves along the guide groove close to one end of the connecting rod, so that the limit rod moves away from one end of the connecting rod to cooperate with the first limit groove.

[0016] By adopting the above technical solution, the spring installed on the limit rod continuously provides elastic force, driving the limit rod to rotate toward the side withdrawal block, ensuring that the limit rod cooperates with the second limit groove in the initial state. When the fan-shaped block moves along the guide groove, the geometric constraint of the groove wall forces the limit rod to overcome the spring elastic force and move toward the side of the first limit groove. During casting, the limit rod is stuck in the second limit groove under the action of the spring and locks the connecting rod; after the casting is completed, the side withdrawal block moves and drives the limit rod into the guide groove, and the guide groove forces the limit rod to rotate and disengage from the second limit groove, and finally cooperate with the first limit groove to lock the side withdrawal block.

[0017] The technical effects of the present invention are mainly reflected in the following aspects: 1. The present invention provides a gate reduction assembly to segment and reduce the gate runner after casting is completed. Gate runners are provided on some side withdrawal blocks, to which sliding blocks are slidably connected. A drive assembly controls the movement of the sliding blocks, which ultimately abut against the fixed mold to segment the gate runners. This reduces the gate size of the molded product, eliminating the need for CNC milling of the gate, allowing direct shearing of the gate, thereby improving the production efficiency of the nine-gate valve body. 2. The present invention uses a hydraulic cylinder to drive the slider to slide on the inclined rail, and cooperates with the limit assembly to achieve the sequential movement of the connecting rod and the side withdrawal block. When the mold is closed, the slider is located on the first and second inclined rails at the same time. The limit assembly limits the position of the slide block on the side withdrawal block, allowing the connecting rod and the side withdrawal block to move synchronously. After casting is completed, the slider moves to the second inclined rail, the limit assembly fixes the side withdrawal block, and the hydraulic cylinder continues to move to drive the connecting rod to drive the slide block to complete the gate reduction. 3. The spring installed on the limit rod of the present invention continuously provides elastic force, driving the limit rod to rotate toward the side withdrawal block, ensuring that the limit rod cooperates with the second limit groove in the initial state. When the fan-shaped block moves along the guide groove, the geometric constraint of the groove wall forces the limit rod to overcome the spring elastic force and move toward the side of the first limit groove. During casting, the limit rod is stuck in the second limit groove under the action of the spring and locks the connecting rod; after the casting is completed, the side withdrawal block moves to drive the limit rod into the guide groove, and the guide groove forces the limit rod to rotate and disengage from the second limit groove, and finally cooperate with the first limit groove to lock the side withdrawal block.

[0028] The following is combined with Figure 1-9 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0029] The embodiment of the present application discloses a nine-port valve body casting mold.

[0030] Reference Figure 1 and Figure 2 , a nine-mouth valve body casting mold of this embodiment includes a fixed mold plate 1 and a movable mold plate 2, and the movable mold plate 2 is slidably connected with several side withdrawal blocks 3 with product molding surfaces along the mold opening direction perpendicular to the mold, and also includes a gate 19 reduction component 4, the gate 19 reduction component 4 is used to reduce the gate 19 after casting is completed, the gate 19 reduction component 4 includes multiple sliding blocks 5 with molding surfaces and a driving component 6, some side withdrawal blocks 3 are opened with multiple gate 19 runners 7, multiple sliding blocks 5 correspond to multiple gate 19 runners 7 respectively, and multiple sliding blocks 5 are respectively slidably connected to the side withdrawal blocks 3 with the gate 19 runners 7, and the driving component 6 is used to drive the movement of the sliding blocks 5 and the side withdrawal blocks 3. When the casting mold completes the casting operation, the multiple sliding blocks 5 move toward one side of the gate 19 runner 7 until they abut on the fixed mold to divide the gate 19 runner 7.

[0031] Reference Figure 2 and Figure 4 By providing a gate 19 reduction assembly 4, the gate 19 runner 7 can be segmented and reduced after casting is completed. The gate 19 runner 7 is opened on some side withdrawal blocks 3, and the sliding block 5 is slidably connected to the side withdrawal block 3. The driving assembly 6 controls the movement of the sliding block 5. Finally, the gate 19 runner 7 is segmented by the sliding block 5 abutting the fixed mold, thereby reducing the gate 19 of the molded product. This eliminates the need for turning and milling the gate 19 on a CNC milling machine, and the gate 19 can be directly sheared, thereby improving the production efficiency of the nine-mouth valve body 20.

[0032] Reference Figure 4 A connecting rod 8 is slidably connected to the side withdrawal block 3 along its sliding direction. Several sliding blocks 5 on the same side withdrawal block 3 are simultaneously fixedly connected to the connecting rod 8. The driving assembly 6 is used to drive the sliding of the connecting rod 8. The driving assembly 6 synchronously drives the movement of multiple sliding blocks 5 by controlling the sliding of the connecting rod 8. The multiple sliding blocks 5 are integrated through the connecting rod 8, avoiding the need to drive each sliding block 5 individually, reducing the complexity and cost of the driving assembly 6. The connecting rod 8 can ensure that the sliding blocks 5 on the same side withdrawal block 3 move synchronously, avoiding asynchronous movements caused by individual driving, and ensuring the accuracy and stability of the gate 19 reduction.

[0033] Reference Figure 4The driving assembly 6 includes a hydraulic cylinder 9 and a limit assembly 10. The side withdrawal block 3 is fixedly connected to a first inclined rail 11, and the connecting rod 8 is fixedly connected to a second inclined rail 12. The connecting rod 8 can be moved to connect the first inclined rail 11 and the second inclined rail 12. The hydraulic cylinder 9 is fixedly connected to the movable template 2, and one end of the piston rod of the hydraulic cylinder 9 is hingedly connected to a slider 13. The slider 13 can be slidably connected to the first inclined rail 11 or the second inclined rail 12. The limit assembly 10 is used to limit the sliding of the connecting rod 8 and the side withdrawal block 3 respectively. During the mold closing process, the sliding block 5 is simultaneously located on the first inclined rail 11 and the second inclined rail 12. The limit assembly 10 limits the position of the sliding block 5 on the side withdrawal block 3. When the casting is completed, the sliding block 5 moves to the second inclined rail 12, and the limit assembly 10 limits the position of the side withdrawal block 3 on the movable mold.

[0034] Reference Figure 2 and Figure 4 The hydraulic cylinder 9 drives the slider 13 to slide on the two inclined rails, cooperating with the limit assembly 10 to achieve the sequential movement of the connecting rod 8 and the side withdrawal block 3. When the mold is closed, the slider 13 is located on the first inclined rail 11 and the second slide rail at the same time. The limit assembly 10 limits the position of the slide block 5 on the side withdrawal block 3, allowing the connecting rod 8 and the side withdrawal block 3 to move synchronously. After casting is completed, the slider 13 moves to the second inclined rail 12, the limit assembly 10 fixes the side withdrawal block 3, and the hydraulic cylinder 9 continues to move to drive the connecting rod 8 and the slide block 5 to complete the reduction of the gate 19.

[0035] Reference Figure 1 and Figure 2 The movement direction of the piston rod is inclined relative to the movement direction of the side withdrawal block 3. The movement direction of the piston rod is inclined relative to the movement direction of the side withdrawal block 3, so that the slider 13 can slide along the first inclined rail 11 and the second inclined rail at the same time during mold closing. After casting is completed, the slider 13 moves to the second inclined rail 12.

[0036] Reference Figure 3 and Figure 4 The limiting assembly 10 includes a limiting rod 14, a first limiting groove 15 is opened on the fixed mold, and a second limiting groove 16 is opened on the side wall of the connecting rod 8. The limiting rod 14 is slidably connected to the side drawer block 3 along a sliding direction perpendicular to the sliding direction of the connecting rod 8. The two ends of the limiting rod 14 in the length direction can respectively cooperate with the first limiting groove 15 and the second limiting groove 16. During the casting process, one end of the limiting rod 14 moves to cooperate with the second limiting groove 16. When the casting is completed, the other end of the limiting rod 14 moves to cooperate with the first limiting groove 15.

[0037] Reference Figure 4 and Figure 5During casting, the limiting rod 14 cooperates with the second limiting groove 16 to lock the connecting rod 8, preventing the sliding block 5 from moving and affecting the stability of the gate 19 runner 7. After casting, the limiting rod 14 cooperates with the first limiting groove 15 to lock the side withdrawal block 3, ensuring that the side withdrawal block 3 is stationary when the hydraulic cylinder 9 drives the connecting rod 8. The driving assembly 6 also includes a spring 17, which is installed on the limit rod 14. The two ends of the spring 17 are respectively in contact with the limit rod 14 and the movable mold. The spring 17 always drives the limit rod 14 to move toward the side of the connecting rod 8. A guide groove 18 is also provided on the side wall of the connecting rod 8. The guide groove 18 is connected to the second limit groove 16. The guide groove 18 gradually becomes closer to the side wall of the connecting rod 8 from the side close to the second limit groove 16 to the side away from the second limit groove 16. When the casting is completed, the end of the limit rod 14 close to the connecting rod 8 moves along the guide groove 18, so that the limit rod 14 moves away from the end of the connecting rod 8 to cooperate with the first limit groove 15.

[0038] Reference Figure 4 and Figure 6 The spring 17 installed on the limit rod 14 continuously provides elastic force, driving the limit rod 14 to rotate toward the side withdrawal block 3, ensuring that the limit rod 14 cooperates with the second limit groove 16 in the initial state. When the limit rod 14 moves along the guide groove 18, the geometric constraint of the groove wall forces the limit rod 14 to overcome the elastic force of the spring 17 and move toward the side of the first limit groove 15. During casting, the limit rod 14 is stuck in the second limit groove 16 under the action of the spring 17, locking the connecting rod 8; after the casting is completed, the side withdrawal block 3 moves to drive the limit rod 14 into the guide groove 18, and the guide groove 18 forces the limit rod 14 to rotate and disengage from the second limit groove 16, and finally cooperates with the first limit groove 15 to lock the side withdrawal block 3.

[0039] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
