Description

Technical Field

[0001] This invention belongs to the field of forging equipment technology, specifically relating to a forging and forming equipment for automotive parts flanges. Background Technology

[0002] Flange forging equipment is a device that uses a forging press to apply pressure to a heated metal billet, causing it to flow in a die cavity and forging flange parts.

[0003] Traditional forging presses mostly use mechanical demolding structures, that is, ejector pins directly eject the parts. During hot forging, the flange parts have a large adhesion force to the cavity interface after high-temperature forming, and there is static friction locking in a vacuum state, which can easily lead to edge damage, deformation, or even local tearing of the flange.

[0004] The surface temperature of hot-forged parts exceeds 300–400°C. If traditional top-sprayed release agent is used, the droplets will instantly generate film boiling upon contact with the high-temperature surface, forming a vapor film that hinders the release agent from penetrating the gaps, resulting in low adhesion efficiency and easy evaporation and loss. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automotive parts flange forging and forming equipment to solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automotive parts flange forging and forming equipment includes a forging press unit and a fixed mold assembly. The forging press unit includes a bottom mold platform, and a fixed mold assembly is fixedly assembled inside the bottom mold platform. The fixed mold assembly includes a fixed mold body and a flange cavity. The flange cavity is provided on the fixed mold body, and a plurality of demolding holes are arranged at the bottom of the flange cavity. Several demolding mechanisms are slidably assembled in several demolding holes. The demolding mechanisms are used to lift the flange parts during the demolding process. The demolding mechanisms include a demolding rod and an inner guide tube. The inner guide tube is slidably inserted into the inner cavity of the demolding rod and is connected to the flange cavity for injecting demolding agent into the flange cavity. The automotive parts flange forging equipment also includes a collision assembly, which comprises several collision blocks. The collision blocks reciprocate in the vertical direction and continuously collide with the bottom die table to vibrate and separate the flange parts that are tightly clamped on the forging press unit.

[0007] As a further embodiment of the present invention, the fixed mold assembly further includes a clamping mold, a limiting cavity, and a pipe hole. The clamping mold is fixedly connected to the bottom of the fixed mold body, and the clamping mold is provided with a plurality of limiting cavities arranged coaxially with the demolding holes. The bottom of the limiting cavity is connected to the pipe hole.

[0008] As a further embodiment of the present invention, the collision assembly further includes a guide shaft, a support plate, a slide, a first elastic element, and a driven rack. The guide shaft is fixedly mounted on the bottom of the bottom mold platform, the support plate is fixedly mounted between two adjacent sets of guide shafts, the slide is slidably arranged on the guide shaft, and the first elastic element is arranged between the bottom of the slide and the support plate. The collision block is fixedly mounted in the slide, and a driven rack is also fixedly mounted at one end of the collision block.

[0009] As a further embodiment of the present invention, the demolding mechanism further includes a limiting boss and a third elastic element. The limiting boss is fixedly arranged on the outer diameter end of the demolding rod, and the limiting boss is slidably assembled in the limiting cavity. The outer diameter end of the demolding rod is also sleeved with a third elastic element, which movably abuts against the limiting cavity.

[0010] As a further embodiment of the present invention, the demolding mechanism further includes a conical seal, an inner guide tube, a conical rod head, a spacer cavity, and overflow holes. The top side of the demolding rod is provided with a conical seal, and the top of the inner guide tube is provided with a conical rod head, which is limited and assembled in the conical seal. The outer diameter end of the inner guide tube is also provided with a spacer cavity, and a gap is provided between the spacer cavity and the conical seal. Several overflow holes are also provided on the wall side of the inner guide tube.

[0011] As a further embodiment of the present invention, the automotive parts flange forging and forming equipment further includes a base plate component. The base plate component includes a base plate body, a central shaft, connecting pins, and a limiting bottom rod. The base plate body is disposed at the bottom of the bottom mold table, and a central shaft is disposed in the middle of the base plate body. The central shaft is fixedly assembled at the bottom of the bottom mold table, and the base plate body is slidably assembled on the central shaft. Several connecting pins are also disposed on the base plate body, and the bottom of the demolding rod is fixedly assembled in the connecting pins. The base plate component further includes a gear shaft component, an elastic gear plate, and a reset cylinder. One end of the gear shaft component is fixedly assembled at the bottom of the bottom mold table, and the other end of the gear shaft component passes through the base plate body. One end of the elastic gear plate component is movably abutting against the gear shaft component, and the other end of the elastic gear plate component is assembled and connected to the reset cylinder. The reset cylinder is fixedly disposed on the base plate body.

[0012] As a further embodiment of the present invention, the base plate component further includes a tube frame, a flow guide, and a flow guide pipe. The tube frame is fixedly arranged at the bottom of the forging press housing. Several flow guides are provided on the tube frame. The bottom of the inner guide pipe passes through the base plate body and is fixedly connected to the flow guide. The flow guide pipe is inserted into the flow guide and is connected to several inner guide pipes. The base plate component further includes a driver, a drive wheel, a driven wheel, a shaft disc, and a residual tooth ring. The driver is fixedly arranged at the bottom of the bottom die table. One end of the drive wheel is connected to the driver for transmission, and the other end of the drive wheel is connected to the driven wheel for transmission. The driven wheel is fixedly arranged at the bottom of the bottom die table. The two ends of the driven wheel are coaxially mounted with shaft discs. The surface of the shaft disc is provided with a residual tooth ring, which is movably engaged with the driven rack.

[0013] As a further embodiment of the present invention, the collision assembly further includes a C-shaped plate, a collar, and a second elastic element. One end of the C-shaped plate is fixedly disposed at the bottom of the collision block, and the other end of the C-shaped plate is fixedly fitted with a collar. The collar is slidably sleeved on the limiting bottom rod, and the second elastic element is sleeved on the surface of the limiting bottom rod and disposed between the collar and the bottom plate.

[0014] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art: This invention uses a collision component to periodically compress an elastic element and release it quickly, forming a controllable impact frequency. The base plate is connected to multiple demolding rods, enabling all the ejector rods to rise synchronously, ensuring uniform force on the bottom surface of the flange. The collar buffers and pushes the base plate after the collision, ensuring that the demolding rods move closely with the bottom of the part, preventing local voids and forming stable support. Furthermore, the reciprocating impact of the collision component and the unidirectional limiting linkage of the base plate component enable progressive demolding. The collision block instantaneously impacts the bottom mold table to generate inertial displacement, creating a gap between the flange parts and the cavity wall, thus avoiding stress concentration caused by direct ejection. At the same time, the demolding rod moves upward synchronously with the lifting of the parts, always providing uniform bottom support and preventing the parts from deforming and cracking due to local stress. It is suitable for safe demolding of high temperature and thin-walled flanges. Furthermore, the release agent is stored through an internal conduit and is sprayed out only through the conical sealing gap when the release rod is lifted, injecting it into the gap between the part and the cavity. This avoids the film boiling phenomenon that occurs when conventional release agents are sprayed, ensuring that the release agent effectively spreads to form a lubricating film. At the same time, the release agent directly exchanges heat with the bottom of the high-temperature flange, reducing the temperature of the contact area, causing the metal to shrink and deform slightly, reducing the interface pressure, reducing frictional resistance, and reducing the risk of tearing and sticking to the mold.

Detailed Implementation

[0027] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please see Figures 1-11According to one embodiment of the present invention, an automotive parts flange forging and forming equipment has a first direction x, a second direction y, and a third direction z. The automotive parts flange forging and forming equipment includes a forging press unit 1 and a fixed mold assembly 2. The forging press unit 1 includes a bottom mold platform 102, and the fixed mold assembly 2 is fixedly assembled inside the bottom mold platform 102. The fixed mold assembly 2 includes a fixed mold body 201 and a flange cavity 202. The flange cavity 202 is provided on the fixed mold body 201, and a plurality of demolding holes 203 are arranged at the bottom of the flange cavity 202. A plurality of demolding mechanisms 4 are slidably assembled on the plurality of demolding holes. In section 203, the demolding mechanism 4 is used to lift the flange parts during the demolding process. The demolding mechanism 4 includes a demolding rod 401 and an inner guide tube 405. The inner guide tube 405 is slidably inserted into the inner cavity of the demolding rod 401 and is connected to the flange cavity 202 for injecting a demolding agent into the flange cavity 202. The automotive parts flange forging and forming equipment also includes a collision assembly 3. The collision assembly 3 includes several collision blocks 305. The collision blocks 305 reciprocate in the vertical direction and continuously collide with the forging press housing 101 for vibration separation of the flange parts tightly clamped on the forging press unit 1.

[0029] In practical application, the main structure of the automotive parts flange forging equipment consists of a forging press unit 1 and a fixed mold assembly 2. The forging press unit 1 includes a forging press housing 101, a bottom mold platform 102, guide pillars 103, a top plate 104, a closing mold 105, and a hydraulic press 106. The bottom mold platform 102 is fixedly mounted on the forging press housing 101. Four sets of guide pillars 103 are vertically arranged along the z-axis on the bottom mold platform 102. The top plate 104 is fixedly mounted on the top of the guide pillars 103. The hydraulic press 106 is arranged on the top of the top plate 104. The bottom end of the machine 106 is connected to the mold plate 105. The mold plate 105 is slidably mounted on the guide post 103, and a moving mold is fixedly mounted on the mold plate 105. The fixed mold assembly 2 is provided with a flange cavity 202 for flange forging. Several demolding holes 203 are arranged circumferentially along the z-axis on the bottom side of the flange cavity 202. The demolding mechanism 4 passes through the demolding holes 203. The bottom side of the flange cavity 202 is a first plane a1. The top end faces of several demolding mechanisms 4 are arranged coplanarly with the first plane a1. The demolding mechanism 4 includes a hollow demolding rod 401 and an inner conduit 405 slidably disposed on the inner cavity side of the demolding rod 401. The end of the inner conduit 405 is connected to an external demolding agent injection pipe. During the flange forging process, the fluid passage between the inner conduit 405 and the inner cavity of the flange cavity 202 is disconnected, and the demolding agent is temporarily stored in the hollow cavity inside the demolding rod 401 and does not contact the flange parts during forging. When the forging process ends and the moving mold retracts, the mold release mechanism 4 is located on the bottom side of the bottom mold platform 102. Driven by the driving source, the collision block 305 can perform controllable reciprocating linear motion along the z-axis. When the collision block 305 accelerates along the positive z-axis and approaches the bottom mold table 102, the impact kinetic energy of the collision block 305 hits the lower surface of the bottom mold table 102, causing the entire bottom mold table 102 and the fixed mold assembly 2 fixed on it to generate instantaneous acceleration, thereby causing the flange parts in the cavity to obtain inertia along the positive z-axis. This inertia causes the flange parts to generate micron-level displacement relative to the inner wall of the flange cavity 202. When the adhesion between the flange part and the cavity wall is too large, compared with the mechanical structure of direct ejection by ejector pins, this impact-type demolding can effectively reduce the risk of flange edge scratches, deformation and local tearing. At the same time, when the above impact occurs, the inner guide tube 405 moves axially relative to the demolding rod 401, so that the fluid channel between the outlet end of the inner guide tube 405 and the inner cavity of the flange cavity 202 is connected, and the release agent is sprayed into the gap between the bottom surface of the flange part and the flange cavity 202. Each impact is accompanied by the inner guide tube 405 spraying the release agent. The mechanical vibration generated during the impact process helps to break the interfacial adhesion between the flange part and the mold cavity, break the interface vacuum state and static friction lock formed by high temperature and high pressure molding, and the subsequently sprayed release agent can quickly spread at the interface and form a continuous and stable lubricating film, reducing demolding resistance. The synergistic effect can greatly reduce the mechanical ejection force applied by the demolding mechanism 4, and smoothly eject the flange part from the flange cavity 202 with a lower defect rate.

[0030] Furthermore, since the surface temperature of hot-forged parts often exceeds 300–400°C, when water-based release agent is sprayed onto its surface, the bottom of the droplet undergoes violent vaporization upon contact with the high-temperature surface, forming a continuous and unstable vapor film, i.e., film boiling. This vapor film has the characteristics of low thermal conductivity and high fluidity, which can lift the droplet away from the surface of the part and inhibit the direct contact between the release agent and the substrate. Under these conditions, the release agent cannot effectively penetrate into the gap between the part and the mold, but instead evaporates or rolls off the surface of the part, thereby reducing the adhesion efficiency of the release agent. In this embodiment, the bottom spraying method triggers the spraying device located at the bottom when the flange part undergoes a slight displacement relative to the mold cavity under ejection or external force. This injects the release agent into the gap between the lower end face of the part and the mold cavity surface, allowing the release agent fluid molecules to rapidly spread along the gap and form a lubricating medium film. Simultaneously, in addition to its lubricating function, the injected release agent also directly exchanges heat with the bottom of the high-temperature flange part, carrying away a large amount of heat from that area and triggering localized structural heat exchange. This heat exchange is limited to the localized area of ​​the bottom of the part near the mold cavity, without changing the mechanical properties and state of the main structure of the part. This effectively reduces the temperature of the contact area, causing the metal material to undergo linear contraction during cooling, which in turn causes the flange part to undergo cold shrinkage deformation, reducing the interface contact pressure between it and the mold. This helps to separate the part from the mold and enhances the demolding effect.

[0031] Please see Figure 4 and Figure 7 In a preferred embodiment of the present invention, the fixed mold assembly 2 further includes a clamping mold 204, a limiting cavity 205, and a pipe hole 206. The clamping mold 204 is fixedly connected to the bottom of the fixed mold body 201. The clamping mold 204 is provided with a plurality of limiting cavities 205 arranged coaxially with the demolding hole 203. The bottom of the limiting cavity 205 is connected to the pipe hole 206. The demolding mechanism 4 further includes a limiting boss 402 and a third elastic element 403. The limiting boss 402 is fixedly arranged at the outer diameter end of the demolding rod 401, and the limiting boss 402 is slidably fitted in the limiting cavity 205. The outer diameter end of the demolding rod 401 is also sleeved with a third elastic element 403, and the third elastic element 403 is movably abutted against in the limiting cavity 205.

[0032] In practical application, the clamping mold 204 has several limiting cavities 205 internally. The diameter of each limiting cavity 205 is configured to be larger than the diameter of the corresponding pipe hole 206, thus forming a stepped diameter structure. The limiting cavity 205 is used to accommodate and restrict the limiting boss 402 provided on the outside of the demolding rod 401, so that the limiting boss 402 can be confined inside the limiting cavity 205 during the axial movement of the demolding rod 401. When the upper end face of the limiting boss 402 abuts against the stepped end face of the limiting cavity 205, the top end face of the demolding rod 401 remains coplanar with the first plane a1, which can effectively prevent the demolding rod 401 from moving in the non-demolding direction. The mold stage protrudes from the first plane a1 to prevent the demolding rod 401 from mechanically interfering with the mold closing or blank forming process in the forging process. The third elastic element 403 is sleeved on the outside of the demolding rod 401. One end of the elastic element abuts against the lower end face of the limiting boss 402, and the other end abuts against the corresponding step or support structure inside the clamping mold 204. The third elastic element 403 provides a continuous elastic preload force, so that the demolding rod 401 remains stationary in the initial position where the limiting boss 402 abuts against the step surface of the limiting cavity 205 when it is not subjected to external lifting or forging pressure, thus ensuring the positional stability of the demolding rod 401 in the non-working state.

[0033] Please see Figure 6 and Figure 10 In a preferred embodiment of the present invention, the collision assembly 3 further includes a guide shaft 301, a support plate 302, a slide 303, a first elastic element 304, and a driven rack 306. The guide shaft 301 is fixedly mounted on the bottom of the bottom mold platform 102. The support plate 302 is fixedly mounted between two adjacent sets of guide shafts 301. The slide 303 is slidably arranged on the guide shaft 301, and the first elastic element 304 is arranged between the bottom of the slide 303 and the support plate 302. The collision block 305 is fixedly mounted in the slide 303, and a driven rack 306 is also fixedly mounted on one end of the collision block 305.

[0034] In practical application, the guide shaft 301 is fixedly mounted on the bottom end face of the bottom mold platform 102, and the slide 303 is slidably mounted on the surface of the guide shaft 301, allowing for reciprocating linear motion along the z-axis. A first elastic element 304 is provided between the slide 303 and the support plate 302. When no external force is applied, the slide 303 and the collision block 305 connected above it maintain a preset axial distance from the lower end face of the bottom mold platform 102. When an external load is applied to the collision block 305 and causes it to move along the negative z-axis, the force is transmitted to the first elastic element 304 through the slide 303, causing the first elastic element 304 to be compressed axially. Its elastic deformation increases continuously with the increase of the external force, thereby continuously accumulating elastic potential energy. At this time, the slide 303... 03 Slides downward along guide shaft 301 until the external force reaches its maximum value or the movement limit position. After the negative z-axis external force applied to collision block 305 is removed, the constraint conditions that originally restricted the movement of slide table 303 and collision block 305 are eliminated. At this time, the first elastic element 304 returns to its original size from the compressed state and quickly converts the accumulated elastic potential energy into the kinetic energy of collision block 305. Under this energy release action, collision block 305 gains accelerated movement along the positive z-axis and has an instantaneous rigid collision with the lower end face of bottom mold table 102 with a certain initial velocity. This rigid impact is transmitted through bottom mold table 102 to the flange inside flange cavity 202, causing the flange part to be subjected to a short and high-intensity mechanical impact in its installation cavity, thereby causing a small relative displacement between the flange part and the inner wall of the cavity.

[0035] Please see Figure 8 In a preferred embodiment of the present invention, the demolding mechanism 4 further includes a conical seal 404, an inner conduit 405, a conical rod head 406, a spacer cavity 407, and an overflow hole 408. The top side of the demolding rod 401 is provided with a conical seal 404, and the top of the inner conduit 405 is provided with a conical rod head 406, which is limited and assembled in the conical seal 404. The outer diameter end of the inner conduit 405 is also provided with a spacer cavity 407, and a gap is provided between the spacer cavity 407 and the conical seal 404. The wall side of the inner conduit 405 is also provided with a plurality of overflow holes 408.

[0036] In practical application, the demolding rod 401 has a relative contracted state and an extended state. In the non-stressed state, the demolding rod 401 is in the contracted state. At this time, the conical seal 404 and the conical rod head 406 are tightly fitted to form a closed sealing interface, ensuring that the demolding agent stored in the inner cavity of the inner conduit 405 is effectively sealed inside the demolding rod 401 to prevent premature leakage. The top of the conical seal 404 is provided with a relative second plane a2, and the top of the conical rod head 406 is provided with a relative third plane a3. When the demolding rod 401 is in the non-stressed contracted state, the second plane a2 and the third plane a3 are both coplanar with the first plane a1 of the bottom mold table 102, ensuring that the bottom of the flange cavity 202 can form a complete continuous plane without protrusions or depressions during the forging process of the flange parts, avoiding defects or dimensional deviations at the bottom of the forging due to uneven bottom structure. When the ejector rod 401 moves along the positive z-axis under the action of external ejection force, since the inner guide tube 405 is fixedly assembled at the bottom of the bottom mold platform 102, the inner guide tube 405 remains stationary relative to the bottom mold platform 102. Therefore, the ejector rod 401 produces an upward sliding displacement relative to the inner guide tube 405. At this time, the axial contact between the originally tightly fitted conical seal 404 and the conical rod head 406 is released, and the radial gap between them increases continuously as the upward movement distance of the ejector rod 401 increases. As the pressure difference increases, the release agent stored in the inner cavity of the inner conduit 405 first enters the spacer cavity 407 through the overflow hole 408 opened on the side wall of the release rod 401. The spacer cavity 407 is located inside the release rod 401 and is axially connected to the gap area between the conical seal 404 and the conical rod head 406. The release agent then continues to flow upward along the spacer cavity 407 and finally enters the gradually expanding annular gap between the conical seal 404 and the conical rod head 406. Because the radial dimension of the gap between the conical seal 404 and the conical rod head 406 is small, when the release agent flows through this narrow gap under the action of external ejection pressure or the dynamic pressure of the liquid itself, the flow velocity of the release agent at the outlet of the gap increases sharply, while the static pressure decreases, forming a jet flow with radial velocity. The release agent thus enters the gap between the inner wall of the flange cavity 202 and the outer surface of the flange part. This jetting action enables the release agent to be evenly covered on the contact surface between the flange part and the cavity, improving the filling efficiency and coverage uniformity of the release agent, effectively reducing the demolding resistance after forging, and reducing the risk of surface scratches or sticking to the mold.

[0037] Please see Figure 7 and Figure 11In a preferred embodiment of the present invention, the automotive parts flange forging and forming equipment further includes a base plate component 5. The base plate component 5 includes a base plate body 501, a central shaft 502, a connecting pin head 503, and a limiting bottom rod 504. The base plate body 501 is arranged at the bottom of the bottom mold table 102. The central shaft 502 is arranged in the middle of the base plate body 501. The central shaft 502 is fixedly assembled to the bottom of the bottom mold table 102, and the base plate body 501 is slidably assembled on the central shaft 502. A plurality of connecting pin heads 503 are also arranged on the base plate body 501. The bottom of the demolding rod 401 is fixedly assembled in the connecting pin heads 503.

[0038] In practical application, the base plate 501 is slidably mounted on the central shaft 502, and the base plate 501 is fixedly connected to several demolding rods 401. When the base plate 501 moves up and down along the z-axis, it can synchronously drive several demolding rods 401 to move in the same direction along the z-axis. The base plate 501 and the central shaft 502 form a sliding fit. The central shaft 502 acts as a guide element, limiting the movement trajectory of the base plate 501 in the z-axis direction. The base plate 501 and the demolding rods 401 are rigidly fixedly connected. When an external force drives the base plate 501 to move in the positive or negative z-axis direction, the movement is directly transmitted to each demolding rod 401 through the fixed connection structure, so that all demolding rods 401 move synchronously along the z-axis at equal distances in the same direction, realizing the demolding action of multi-rod linkage, and ensuring the consistency of movement of the demolding rods 401 and the base plate 501 in the z-axis direction.

[0039] Furthermore, the base plate component 5 also includes a gear shaft 505, an elastic gear plate 506, and a reset cylinder 507. One end of the gear shaft 505 is fixedly mounted to the bottom of the forging press housing 101, and the other end of the gear shaft 505 passes through the base plate body 501. One end of the elastic gear plate 506 is movably abutting against the gear shaft 505, and the other end of the elastic gear plate 506 is assembled and connected to the reset cylinder 507. The reset cylinder 507 is fixedly arranged on the base plate body 501, and the gear shaft 505 is fixedly installed on the bottom of the bottom die table 102. The elastic gear plate 506 and the gear shaft 505 are engaged by a movable abutment. The elastic gear plate 506 is provided with a plurality of elastic gears that can rotate around their respective axes. When the base plate body 501 moves linearly along the positive z-axis, the elastic gear plate 506... The elastic teeth on 06 slide relative to each other on the outer surface of the gear shaft 505. By utilizing the friction of the tooth surface and the one-way locking characteristics, the displacement of the base plate 501 relative to the gear shaft 505 in the negative z-axis direction is restricted, thereby realizing the one-way movement limit function of the base plate 501 in the positive z-axis direction. The purpose is that when the external flange part is subjected to the instantaneous impact of the collision block 305 and is displaced in the positive z-axis direction, the base plate 501 simultaneously bears the thrust in the positive z-axis direction. This thrust causes the several demolding rods 401 fixed on the base plate 501 to rise synchronously in the positive z-axis direction, thereby pressing the top end face of each demolding rod 401 against the bottom surface of the flange part in an elastic pre-tightening manner, thereby effectively filling the gap between the flange part and the bottom of its molding cavity. During this process, the top of the release rod 401 serves as a new bottom support surface for the flange part, causing the flange part to continuously rise in the positive z-axis direction until it is completely separated from the cavity. Simultaneously, as the gap between the flange part and the cavity expands, the release agent continuously flows in the gap area, thereby achieving efficient cooling of the flange part and preventing deformation due to heat accumulation. After the flange part is completely separated from the cavity, the reset cylinder 507 drives the elastic toothed plate 506 to perform a retraction action, releasing the one-way limiting contact state between the elastic toothed plate 506 and the toothed shaft 505, thereby releasing the movement constraint on the base plate 501 in the negative z-axis direction. The base plate 501 can then reset to its initial position along the z-axis direction.

[0040] Please see Figure 10 and Figure 11In a preferred embodiment of the present invention, the base plate component 5 further includes a pipe rack 508, a flow guide 509, and a flow guide pipe 510. The pipe rack 508 is fixedly arranged on the bottom of the bottom mold platform 102, and a plurality of flow guides 509 are provided on the pipe rack 508. The bottom of the inner conduit 405 passes through the base plate body 501 and is fixedly connected to the flow guide 509. The flow guide pipe 510 is inserted into the flow guide 509 and communicates with the plurality of inner conduits 405. The base plate component 5 also includes a driver 511, a drive wheel 512, and a follower wheel 510. The device comprises a driving wheel 513, a shaft disc 514, and a residual tooth ring 515. The driver 511 is fixedly mounted on the bottom of the bottom mold platform 102. One end of the driving wheel 512 is connected to the driver 511 for transmission, and the other end of the driving wheel 512 is connected to the driven wheel 513 for transmission. The driven wheel 513 is fixedly mounted on the bottom of the forging press housing 101. The two ends of the driven wheel 513 are coaxially mounted with the shaft disc 514. The surface of the shaft disc 514 is provided with a residual tooth ring 515, which is movably meshed with the driven rack 306.

[0041] In practical application, the pipe rack 508 is fixedly installed in the bottom area of ​​the bottom mold platform 102 and is fixedly connected to several longitudinally arranged inner conduits 405 to form an overall support structure. A flow guide 509 is provided at the bottom of the pipe rack 508. The outlet end of the flow guide 509 is connected to one or more flow guide pipes 510. The flow guide pipes 510 are used to deliver the release agent to the internal cavity of each inner conduit 405 by directional pumping, thereby completing the application of the release agent at the working interface. The driver 511 can drive the drive wheel 5 connected to its output end. 12. Continuous rotational motion, and then the kinetic energy is transmitted to the driven wheel 513 through the synchronous belt, so that the driven wheel 513 rotates synchronously. The driven wheel 513 has a shaft disk 514 installed at both ends of the axial direction. The outer diameter end face of the shaft disk 514 is provided with a residual tooth ring 515. The residual tooth ring 515 is composed of several tooth-shaped structures arranged at intervals along the circumferential direction. It has meshing teeth only in a certain angle range of the circumference. When the driven wheel 513 drives the shaft disk 514 to rotate, the residual tooth ring 515 rotates accordingly and gradually approaches and enters the meshing range with the driven rack 306 in its tooth segment area. When the residual tooth ring 515 rotates to a side close to the driven rack 306, the residual tooth ring 515 and the driven rack 306 form a tooth profile mesh, thereby driving the driven rack 306 to move linearly along the negative z-axis. A collision block 305 is fixedly connected to the lower end of the driven rack 306. The collision block 305 moves together with the driven rack 306 along the negative z-axis, and continuously compresses the first elastic element 304 during this movement, causing the first elastic element 304 to continuously accumulate elastic potential energy. When the residual tooth ring 515... As the gear continues to rotate and disengages from the meshing area on one side of the driven rack 306, the tooth profile constraint between the residual tooth ring 515 and the driven rack 306 is released. The driven rack 306 loses its positional restriction on the collision block 305 in the negative z-axis direction. At this time, the elastic potential energy stored in the first elastic element 304 is rapidly released, pushing the collision block 305 to generate high-speed linear motion in the positive z-axis direction. Ultimately, the upper end face of the collision block 305 and the bottom surface of the bottom mold table 102 undergo an instantaneous mechanical collision, thereby forming an impact.

[0042] Furthermore, the collision assembly 3 also includes a C-shaped plate 307, a collar 308, and a second elastic element 309. One end of the C-shaped plate 307 is fixedly disposed at the bottom of the collision block 305, and the other end of the C-shaped plate 307 is fixedly fitted with a collar 308. The collar 308 is slidably sleeved on the limiting bottom rod 504. The second elastic element 309 is sleeved on the surface of the limiting bottom rod 504 and disposed between the collar 308 and the bottom plate 501. The C-shaped plate 307 is fixedly installed on the bottom end face of the collision block 305, forming a rigid connection. When the limiting constraint on one side of the collision block 305 is released, the collision block 305 moves linearly along the positive z-axis and interacts with the bottom mold. When platform 102 generates a mechanical impact, during the impact process, the collar 308 on one side of the collision block 305 slides axially along the limiting bottom rod 504 and applies an axial thrust to the second elastic element 309 sleeved on the outer surface of the limiting bottom rod 504, causing the second elastic element 309 to compress and deform along the limiting bottom rod 504 toward the lower end of the base plate 501. Under the push of the elastic force, the base plate 501 drives several demolding rods 401 rigidly connected to it to slide relative to each other along the bottom direction of the flange part until several demolding rods 401 simultaneously abut against the bottom end face of the flange part, forming a uniformly distributed support contact, thereby achieving bottom support for the flange part.
