[0015] This invention provides a die-casting mold for forging tractor chassis, which has the following advantages:

[0016] 1. During the mold closing process, the present invention uses a drive rod to link the limiting plate and the rotating roller, triggering the energy storage spring to release energy and drive the rubber-coated head to strike the moving mold. The vibration effect promotes the uniform flow of liquid metal and removes air bubbles, improving the casting quality. During demolding, the drive rod is reversed to trigger vibration again to reduce part adhesion. This design achieves adaptive vibration assistance in the molding and demolding stages, and can simultaneously optimize the internal density and demolding smoothness without additional devices, significantly reducing the product defect rate and shortening the production cycle.

[0017] 2. The mold closing mechanism of the present invention controls the insertion and removal of the positioning pin through the coordinated control of the buffer spring and the guide part. When the drive seat moves, it automatically completes the mold clamping and self-locking. When the mold is separated, the compression spring drives the positioning pin to reset and release the lock. The linkage baffle limit ensures the accuracy of the mold separation action. This structure integrates the buffering, clamping, self-locking and unlocking processes into a single drive system, which greatly improves the mold closing stability and operation efficiency, ensuring the safety of mold operation and simplifying the operation process.

[0018] 3. This invention utilizes a reset spring-driven ejector pin and vacuum suction to work in tandem. During mold closing, the reset spring controls the ejector pin to remain flush with the cavity during the liquid injection stage, ensuring the integrity of the molded surface. During demolding, when the ejector pin pushes out the workpiece, the suction pipe generates negative pressure suction through the suction hole at the end of the ejector pin. This prevents the workpiece from falling off and being damaged, reduces the contact area between the workpiece and the inside of the mold cavity, lowers the frictional resistance during part removal, and accelerates the heat dissipation of the workpiece while achieving rapid demolding, thereby improving the production efficiency of tractor chassis parts.

Detailed Implementation

[0026] Please see Figures 1 to 4 This invention provides a technical solution: a die-casting mold for forging a tractor chassis, comprising a first side plate 1 and an exhaust assembly 11. A fixed mold 2 is disposed on one side of the first side plate 1, and a movable mold 3 is disposed on one side of the fixed mold 2. A mold base 4 is fixed on one side of the movable mold 3. Guide rods 5 are fixed at the four corners of one side of the first side plate 1, and the ends of the guide rods 5 are connected to a second side plate 6. A hydraulic cylinder 7 is disposed in the middle of one side of the second side plate 6, and the end of the hydraulic cylinder 7 is connected to a drive seat 8. The drive seat 8 is slidably connected to the guide rods 5. A drive rod 9 is slidably connected inside the mold base 4. The drive rod 9 is fixedly connected to the drive seat 8, and a connecting assembly 10 is connected to one side of the drive seat 8. The connecting assembly 10 includes a buffer spring 1001, and a buffer spring 1001 is connected to one side of the drive seat 8. The driving rod 9 has a guide part 1002 at its end and a limit block 1003 fixed on the outer side of the middle part of the driving rod 9. The fixed mold 2 has connecting blocks 1004 on its upper and lower sides and a positioning pin 1005 slidably connected to the end of the connecting block 1004. The moving mold 3 has positioning holes 1006 on its upper and lower sides and the positioning holes 1006 match the positioning pin 1005. A compression spring 1007 is sleeved on the outer side of the positioning pin 1005 and a connecting plate 1008 is connected to the end of the compression spring 1007. The connecting plate 1008 is fixedly connected to the positioning pin 1005. A pulley 1009 is provided on one side of the connecting plate 1008. The fixed mold 2 has baffles 1010 symmetrically arranged on its upper and lower sides and the baffles 1010 are right angled.

[0027] The specific operation is as follows: When the hydraulic cylinder 7 drives the drive seat 8 to move along the outside of the guide rod 5 towards the first side plate 1, the buffer spring 1001 will first cause the mold base 4 to move together. At this time, the limiting block 1003 will limit the other side of the mold base 4. After the moving mold 3 and the fixed mold 2 are in contact, as the drive seat 8 continues to move, the buffer spring 1001 can play a buffering role to avoid the pressure from increasing instantly and damaging the mold. After the fixed mold 2 and the moving mold 3 are pressed together, as the drive rod 9 continues to move, the inclined guide part 1002 can squeeze the pulley 1009, so that the connecting plate 1008 drives all the positioning pins 1005 to pass through the connecting block 1004 and insert into the positioning hole 1006 on the moving mold 3, automatically aligning the fixed mold 2 and the moving mold 3. The locking mechanism creates a dual fastening structure of clamping and self-locking, which improves the stability of the fixed mold 2 and the moving mold 3 after mold closing. During mold separation, when the drive seat 8 moves the drive rod 9 back to separate it from the pulley 1009, the compression spring 1007 pushes the connecting plate 1008, removing all the positioning pins 1005 from the positioning holes 1006, automatically releasing the connection restriction between the fixed mold 2 and the moving mold 3. Simultaneously, the baffle 1010 limits the movement of the connecting plate 1008. Later, when the drive seat 8 continues to move the drive rod 9, the mold base 4 moves together via the limit block 1003, realizing the mold separation operation between the fixed mold 2 and the moving mold 3. Furthermore, since the clamping and self-locking operations do not require separate control, it is more convenient to use.

[0028] Please see Figures 1 to 5 The exhaust assembly 11 is located at the end of the drive rod 9, and the exhaust assembly 11 includes a rotating shaft 1101. The rotating shaft 1101 is rotatably connected inside the drive rod 9, and a limit plate 1102 is installed at the end of the rotating shaft 1101. A limit post 1103 is fixed on one side of the middle part of the limit plate 1102, and a guide groove 1104 is provided on the outer side of the limit post 1103. A rotating roller 1105 is connected to one side of the limit plate 1102, and one end of the rotating roller 1105... A slide rod 1106 is rotatably connected. A rubber-coated head 1107 is installed at the end of the slide rod 1106. An energy storage spring 1108 is sleeved on the outside of the rubber-coated head 1107. A fixing frame 1109 is connected to the end of the energy storage spring 1108. The fixing frame 1109 is slidably connected to the slide rod 1106 and is fixedly connected to the moving mold 3. The guide groove 1104 is arc-shaped and is equidistantly distributed along the length of the drive rod 9.

[0029] The specific operation is as follows: When the fixed mold 2 and the moving mold 3 are closed, the drive seat 8 will also drive the drive rod 9 to move simultaneously. During the subsequent liquid injection process, as the drive rod 9 continues to move, the limiting plate 1102 will contact the rotating roller 1105. At this time, the guide groove 1104 will restrict the position of the limiting post 1103, so that the limiting plate 1102 remains inclined. Therefore, under the guidance of the inclined surface, the sliding rod 1106 can be pulled by the rotating roller 1105, and the rubber coating head 1107 will separate from the moving mold 3. At the same time, the energy storage spring 1108 is compressed between the rubber coating head 1107 and the fixed frame 1109. When the rotating roller 1105 separates from the limiting plate 1102, the pressure on the rotating roller 1105 is released. With the obstruction of 05, the energy storage spring 1108 can push the rubber-coated head 1107 under the limit of the fixed frame 1109, so that it strikes the moving mold 3. The vibration generated by the strike promotes the uniform flow of liquid metal inside the mold and removes air bubbles, improving the molding effect of the tractor chassis parts. When demolding, when the drive rod 9 moves back, it will first drive the limit plate 1102 to rotate around the pivot 1101. When the limit post 1103 moves to the other end of the guide groove 1104, the limit plate 1102 will tilt. Similarly, the slide rod 1106 can be pulled first and then separated to achieve the striking action again, thereby generating vibration, reducing the adhesion between the parts and the mold cavity, and facilitating the demolding operation of the parts.

[0030] Please see Figure 2 and Figure 6 A demolding assembly 12 is provided on one side of the mold base 4, and the demolding assembly 12 includes a fixing post 1201. The fixing post 1201 is placed on one side of the mold base 4, and a fixing block 1202 is connected to the end of the fixing post 1201. A flow divider plate 1203 is provided on one side of the fixing block 1202, and the flow divider plate 1203 is slidably connected to the fixing post 1201. The interior of the flow divider plate 1203 is hollow. A return spring 1204 is sleeved on the outside of the fixing post 1201. Both ends abut against the mold base 4 and the flow divider plate 1203 respectively. The middle front end of the flow divider plate 1203 is connected to the suction pipe 1205, and an ejector pin 1206 is installed on one side of the flow divider plate 1203. The ejector pin 1206 is slidably connected to the mold base 4. The outer peripheral surface of the end of the ejector pin 1206 is provided with a suction hole 1207, and the suction hole 1207 is connected to the interior of the flow divider plate 1203. A top post 1208 is fixed in the middle of one side of the second side plate 6, and the top post 1208 is slidably connected to the drive seat 8.

[0031] The specific operation is as follows: During the injection process, the return spring 1204 pushes the flow divider plate 1203 to make it fit tightly against the fixing block 1202. Therefore, the end of the ejector pin 1206 will be flush with the internal cavity surface of the moving mold 3, avoiding obstruction of the molding operation of the tractor chassis parts. During mold separation, when the drive rod 9 moves the mold base 4 through the limit block 1003, it will also simultaneously drive the flow divider plate 1203 to move towards the ejector pin 1208. After the flow divider plate 1203 fits against the ejector pin 1208, as the mold base 4 continues to move, the return spring 1204 will contract, and the ejector pin 1206 can slide inside the moving mold 3, ejecting the workpiece from the cavity inside the moving mold 3, realizing the automatic demolding function. At the same time, due to the suction pipe 1205 Connected to an external vacuum pump, when the ejector pin 1206 pushes the workpiece, the suction port 1207 at its end can move into the cavity of the moving mold 3. At this time, starting the vacuum pump can suck the cavity through the suction port 1207, so that a certain suction force is generated inside the moving mold 3, preventing the ejector pin 1206 from pushing out too far and causing the workpiece to fall directly from the moving mold 3 and be damaged. At the same time, since the ejector pin 1206 can push a greater distance, the contact area between the workpiece and the mold cavity can be reduced, which facilitates the subsequent part removal operation. It can also accelerate the airflow around the workpiece, which is beneficial to assist in the cooling of the workpiece. After the workpiece is manually clamped with a clamp, the suction operation is stopped, thus facilitating the removal and unloading of the workpiece.

[0032] In summary, when using this die-casting mold for tractor chassis forging, the hydraulic cylinder 7 first drives the drive seat 8 to move along the outside of the guide rod 5 towards the first side plate 1. The buffer spring 1001 will first cause the mold base 4 to move together. At this time, the limiting block 1003 will limit the other side of the mold base 4. When the moving mold 3 and the fixed mold 2 are in contact, as the drive seat 8 continues to move, the buffer spring 1001 can play a buffering role. After pressing the fixed mold 2 and the moving mold 3 together, as the drive rod 9 continues to move, the inclined guide part 1002 can squeeze the pulley 1009, so that the connecting plate 1008 drives all the positioning pins 1005 to pass through the connecting block 1004 and insert into the positioning hole 1006 on the moving mold 3, automatically locking the fixed mold 2 and the moving mold 3.

[0033] Secondly, during the injection process, the return spring 1204 pushes the flow divider 1203 to make it fit tightly against the fixed block 1202. Therefore, the end of the ejector pin 1206 will be flush with the internal cavity surface of the moving mold 3, avoiding interference with the molding of the tractor chassis parts. Afterward, as the drive rod 9 continues to move, the limiting plate 1102 will come into contact with the rotating roller 1105. At this time, the guide groove 1104 will restrict the position of the limiting post 1103, keeping the limiting plate 1102 tilted. Therefore, under the guidance of the tilted surface, the sliding part can be pulled by the rotating roller 1105. When rod 1106 and rubber-coated head 1107 are separated from moving mold 3, the energy storage spring 1108 is compressed between rubber-coated head 1107 and fixed frame 1109. When rotating roller 1105 is separated from limiting plate 1102, the energy storage spring 1108 can push rubber-coated head 1107 under the limitation of fixed frame 1109, so that it strikes moving mold 3. The vibration generated by the strike promotes uniform flow of liquid metal inside the mold and removes air bubbles, thereby improving the molding effect of tractor chassis parts.

[0034] Then, after cooling and molding, when the hydraulic cylinder 7 controls the drive seat 8 to drive the drive rod 9 to move back, it will first drive the limit plate 1102 to rotate around the pivot 1101. When the limit post 1103 moves to the other end of the guide groove 1104, the limit plate 1102 will tilt again. Similarly, the slide rod 1106 can be pulled and then separated, and the knocking action can be realized again, thereby generating vibration and reducing the adhesion between the part and the mold cavity. Afterwards, when the drive rod 9 separates from the pulley 1009, the compression spring 1007 will push the connecting plate 1008 to move all the positioning pins 1005 out of the positioning hole 1006, automatically releasing the connection restriction between the fixed mold 2 and the moving mold 3. At the same time, the baffle 1010 will limit the movement position of the connecting plate 1008. Subsequently, when the drive seat 8 continues to drive the drive rod 9 to move, the mold base 4 can be moved together through the limit block 1003 to realize the mold separation operation between the fixed mold 2 and the moving mold 3.

[0035] Finally, when the mold base 4 drives the flow divider plate 1203 to fit against the ejector pin 1208, as the mold base 4 continues to move, the return spring 1204 will contract, and the ejector pin 1206 can slide inside the moving mold 3, ejecting the workpiece from the cavity inside the moving mold 3. At the same time, since the suction pipe 1205 is connected to an external vacuum pump, when the ejector pin 1206 pushes the workpiece, the suction hole 1207 at its end can move into the cavity inside the moving mold 3. At this time, starting the vacuum pump can suck the cavity through the suction hole 1207, so that a certain suction force is generated inside the moving mold 3, preventing the ejector pin 1206 from pushing out too far and causing the workpiece to fall directly from the moving mold 3 and be damaged. At the same time, since the ejector pin 1206 can push a greater distance, the contact area between the workpiece and the mold cavity can be reduced, and the airflow around the workpiece can also be accelerated, which is beneficial to assist in the cooling of the workpiece. Afterwards, the suction operation is stopped after the workpiece is manually clamped with a clamp, which facilitates the removal and unloading of the workpiece.
