Description

Technical Field

[0001] This invention relates to the field of hardware processing technology, specifically to a hardware processing mold that facilitates material discharge. Background Technology

[0002] Metal stamping is a processing method that uses an external press and mold to apply external force to a metal sheet, causing plastic deformation or separation, thereby obtaining parts with the required shape, size and performance.

[0003] During the stamping process of metal parts, the metal sheet is first cut to the appropriate size according to requirements, and then precisely placed in the cavity of the stamping die. The stamping equipment is started, and a certain pressure is applied through the punch, causing the raw material to undergo plastic deformation within the die, conforming to the shape of the die cavity to form a preliminary workpiece. After the stamping is completed, the equipment drives the punch to reset, and then the formed metal part is removed from the die manually or by auxiliary devices. However, in the production process of metal stamping parts, the current main reliance is on manual operation for picking up and unloading parts in the mold. Due to the small space inside the mold cavity and the uneven resistance experienced by different parts when demolding, jamming and deflection are very likely to occur. Under such conditions, the operator's working posture is severely restricted, making it difficult to exert effective force. This results in the obstruction of the unloading trajectory of the metal stamping parts, making the unloading action clumsy, inefficient and unstable. This not only seriously affects the production cycle, but also poses hidden dangers to safe production and product surface quality. Summary of the Invention

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0035] Example 1, referring to Figure 1 - Figure 7 This is the first embodiment of the present invention, which provides a hardware parts processing mold for easy material discharge. The device includes: a lower mold base 101, a buffer rod cylinder 102 fixedly connected to the surface of the lower mold base 101, and an upper mold base 103 fixedly connected to the surface of the buffer rod cylinder 102. It also includes: The extension structure 200 includes a mounting groove 201 formed on the surface of the lower mold base 101, a first bottom cylinder 203 movably connected to the surface of the mounting groove 201, a first extension cylinder 2031 slidably connected to the surface of the first bottom cylinder 203, a heightening cylinder 2032 slidably connected to the surface of the first extension cylinder 2031, a packaging box 202 fixedly connected to the surface of the first bottom cylinder 203, a trigger component 205 fixedly connected to the surface of the packaging box 202, and a conduction component 206 fixedly connected to the surface of the trigger component 205. The height can be adjusted to adapt to processing requirements, ensuring material transport and signal transmission, and laying the foundation for gravity monitoring.

[0036] The discharge structure 300 includes a groove 301 formed on the surface of the lower mold base 101 and located on the side of the transmission component 206, a second bottom cylinder 302 movably connected to the surface of the mounting groove 201, a second extension cylinder 3021 slidably connected to the surface of the second bottom cylinder 302, a telescopic component 304 fixedly connected to the surface of the second extension cylinder 3021, and a support component 305 fixedly connected to the telescopic component 304. The height is adjustable, enabling automatic ejection of workpieces, saving labor, improving efficiency, and reducing risks.

[0037] The triggering component 205 includes a fixing ring 2051 fixedly connected to the surface of the packaging box 202, a limiting cylinder 2052 fixedly connected to the surface of the fixing ring 2051 and arranged in a circle, a sliding column 2053 slidably connected to the surface of the limiting cylinder 2052, a connecting plate 2055 fixedly connected to the surface of the sliding column 2053, and a tension spring 2054 fixedly connected between the connecting plate 2055 and the limiting cylinder 2052.

[0038] The connecting plate 2055 has several telescopic rods 2056 arranged in a circular array fixedly connected to its surface. Sealing tubes 2057 are movably connected to the surfaces of the telescopic rods 2056. A punch 104 is fixedly connected to the surface of the lower mold base 101. This ensures stable sliding of the sliding column 2053, assists in the resetting of the connecting plate 2055, and provides energy for the suction backpressure cycle.

[0039] The conductive assembly 206 includes a fixing plate 2061 fixedly connected to the surface of the sealing tube 2057, a corrugated soft cone sleeve 2062 fixedly connected to the surface of the fixing plate 2061 and located at the top of the sealing tube 2057, and an integrated cavity bag 2066 fixedly connected to the surface of the corrugated soft cone sleeve 2062. It adapts to changes in liquid volume, centrally stores liquid to prevent turbulence, and ensures accurate gravity monitoring data. A mounting plate 2063 is fixedly connected to the surface of the fixing plate 2061. The mounting plate 2063 is located directly below the integrated cavity bag 2066. An infusion tube 2064 is fixedly connected to the surface of the mounting plate 2063. One end of the infusion tube 2064 is fixedly connected to the surface of the integrated cavity bag 2066, and the other end of the infusion tube 2064 is fixedly connected to a storage bag 2065. A gravity sensor 2067 is fixedly connected to the center point of the mounting plate 2063, located on the surface of the integrated cavity bag 2066. This system enables liquid circulation and recovery, while the gravity sensor 2067 controls the discharge, achieving fully automatic circulation.

[0040] During use, the lower die holder 101 and the upper die holder 103 on the surface of the buffer cylinder 102 come into contact and separate during the stamping process, thus achieving stamping. During stamping, when the upper die holder 103 moves upward and separates from the lower die holder 101, the resulting tension is transmitted through the pull rope 3043 and the buckle 3046 on the pull rope 3043, causing the heightening cylinder 2032 to move along the first extension cylinder 2031, and also causing the first extension cylinder 2031 to move along the first bottom cylinder 2031. 03. When the lower mold base 101 and the upper mold base 103 are in contact, the sliding column 2053 moves away from the fixed ring 2051 relative to the externally slidingly connected limiting cylinder 2052. The tension spring 2054 is in a stretched state. Since the sliding column 2053 is connected to components such as the telescopic rod 2056 and the sealing tube 2057 through the connecting plate 2055, it drives the connecting rod and the telescopic rod 2056 to move. The telescopic rod 2056 performs piston movement in the sealing tube 2057, generating suction and repulsion.

[0041] When the upper die holder 103 and the lower die holder 101 separate, it indicates that one stamping operation has been completed. In the separated state, the tension generated by the upper die holder 103 drives the extension cylinder 2032 to move upward along the first extension cylinder 2031 and the first extension cylinder 2031 to move upward along the first bottom cylinder 203 through the pull rope 3043 and the buckle 3046 on the pull rope 3043. At this time, the telescopic component 304 disengages from the surface of the connecting plate 2055. When the connecting plate 2055 moves away from the sealing tube 2057 under the force-driven mechanism, the telescopic rod 2056 fixed to the connecting plate 2055 is pulled outward from the internal cavity of the sealing tube 2057 a certain distance. The withdrawal of the telescopic rod 2056 causes the space originally occupied by the rod inside the sealing tube 2057 to expand instantaneously, thereby increasing the space inside the sealing tube 2057. A local negative pressure is formed in the inner cavity of 057. This negative pressure effect acts on the infusion tube 2064 system connected to the sealing tube 2057 through the fixing plate 2061. Since the reservoir bag 2065 contains liquid, and the infusion tube 2064 connects the reservoir bag 2065, the integrated cavity bag 2066, and the corrugated soft cone sleeve 2062 to form a closed fluid passage, under the action of pressure difference, the liquid in the reservoir bag 2065 is drawn into the infusion tube 2064 and flows upward along the pipe. After passing through the inlet on the mounting plate 2063, it is finally injected into and filled into the integrated cavity bag 2066 and the corrugated soft cone sleeve 2062 connected to it along the infusion tube 2064. As the liquid flows in, the integrated cavity bag 2066 and the corrugated soft cone sleeve 2062, which were originally in a relaxed or contracted state, begin to expand, and the weight of the internal liquid gradually increases.

[0042] Immediately afterwards, the upper mold base 103 begins to descend, and the pressure applied to the extension structure 200 increases rapidly. The tension spring 2054 contracts, pulling the connecting plate 2055 back to the direction of the limiting cylinder 2052. The resetting action of the connecting plate 2055 pushes all the telescopic rods 2056 to insert into the inner cavity of the sealing tube 2057 simultaneously. The telescopic rods 2056 re-enter the sealing tube 2057, occupying the internal space and exerting a squeezing effect on the liquid or gas inside the tube. The liquid is then transferred to the storage bag 2065 through the infusion tube 2064. A portion of the liquid that just flowed into the integrated cavity bag 2066 and the corrugated soft cone sleeve 2062 returns to the storage bag 2065 along the original path through the infusion tube 2064. With the return of the liquid, the volume of the integrated cavity bag 2066 and the corrugated soft cone sleeve 2062 shrinks, the amount of liquid contained inside decreases, and the overall weight decreases accordingly.

[0043] The gravity sensor 2067, fixed at the center point of the mounting plate 2063, directly supports the assembly of the integrated cavity bag 2066 and the corrugated soft cone sleeve 2062. Therefore, with each pressing cycle—that is, each downward and upward movement of the upper die holder 103—the reciprocating motion of the connecting plate 2055 and the telescopic rod 2056 completes one complete suction and backpressure cycle, causing a periodic increase or decrease in the amount of liquid in the integrated cavity bag 2066 and the corrugated soft cone sleeve 2062. The gravity sensor 2067 continuously and with high sensitivity monitors this weight change caused by the liquid flow. The gravity sensor 2067 measures and... Instead of an absolutely static weight value, it refers to the dynamic rate of change or magnitude of weight change per unit time. The control system presets a weight change threshold, which corresponds to the amount of liquid transferred in one effective and complete stamping stroke. When a stamping action is completed, and the weight increase signal detected by the gravity sensor 2067 reaches or exceeds the preset threshold, a clear electrical signal is immediately generated and sent to the support component 305 of the discharge structure 300, instructing the support component 305 to start and perform the workpiece ejection operation, eliminating the safety risks and discharge speed caused by operators manually picking up the workpiece.

[0044] It achieves a fully automated cycle of material output as soon as the mold opens, seamlessly embedding the material output action into the stamping cycle, transforming the part picking process, which previously relied on manual judgment and intervention and was prone to interrupting the production process, into an efficient, continuous and uninterrupted automated step.

[0045] Example 2, refer to Figure 1 - Figure 8 This is the second embodiment of the present invention, which differs from the first embodiment in that: the telescopic component 304 includes a support base 3041 fixedly connected to the surfaces of the heightening cylinder 2032 and the second extension cylinder 3021, a limiting hole 3042 formed on the surface of the support base 3041, a pull rope 3043 slidably connected to the surface of the limiting hole 3042 and fixedly connected at one end to the surface of the lower mold base 101, a buckle 3046 fixedly connected to the surface of the pull rope 3043, and a positioning piece 3045 fixedly connected to the surface of the heightening cylinder 2032 and located directly above the buckle 3046. The components are stably lifted in the order of first heightening, then synchronization, and finally extension. The workpiece is sequentially loosened, completely demolded, and automatically slid out. The ejection stroke is short and accurate, the mold does not require an additional power source, the structure is compact, and the number of failure points is reduced.

[0046] Compared to the previous embodiment, further, guide plates 3047 are fixedly connected to the surfaces of the first extension tube 2031 and the second extension tube 3021, respectively. A control belt 3048 is slidably connected to the surface of the guide plate 3047, and a gravity block 3049 is fixedly connected to the top end of the control belt 3048. By using its own weight to press or release the connecting plate 2055, the telescopic rod 2056 can start and stop without electrical control, which is simple and reliable.

[0047] Furthermore, an inner support ring 204 is fixedly connected to the surface of the first bottom cylinder 203 and the surface of the packaging box 202, and an expansion ring 303 is fixedly connected to the surface of the second bottom cylinder 302. This serves two purposes: firstly, to support the bottoms of the first bottom cylinder 203 and the second bottom cylinder 302 respectively; and secondly, to facilitate the movement of the control belt 3048 and the gravity block 3049 to the surfaces of the groove 301 and the connecting plate 2055. The inner support ring 204 supports the bottom end of the first bottom cylinder 203, and the expansion ring 303 grips the outer wall of the second bottom cylinder 302. With the two rings coaxially positioned, the cylinder rises and falls without wobbling, thus keeping the guide plate 3047 vertical. The control belt 3048 always slides in the center, avoiding uneven wear and jamming, and ensuring accurate alignment of the latch 3046 and the limiting hole 3042 even during long-term operation.

[0048] During use, the first bottom cylinder 203 and the second bottom cylinder 302 are at the same height as the first extension cylinder 2031, the second extension cylinder 3021, and the raising cylinder 2032. A buckle 3046 is fixedly connected to the top of the pull rope 3043 in the second bottom cylinder 302. Buckles 3046 are also fixedly connected to the surfaces of the pull rope 3043 inside the first bottom cylinder 203 and the raising cylinder 2032. When a stamping operation is completed and the upper die holder 103 begins to move upward and disengage from the lower die holder 101, the upper die holder 103 is fixed to the lower die holder 101. The pull rope 3043 on the surface is tightened by the upward movement of the upper mold base 103. First, the pull rope 3043 located inside the first bottom cylinder 203 and the buckle 3046 on its surface move upward. During the upward movement, the buckle 3046 contacts the positioning piece 3045 fixedly connected to the bottom of the extension cylinder 2032, thereby driving the entire extension cylinder 2032 to slide upward along the surface of the first extension cylinder 2031. This action causes the top of the extension cylinder 2032 to lift the stamped workpiece from the punch 104 on the surface of the lower mold base 101, thus achieving initial demolding.

[0049] As the upper mold base 103 continues to rise, the pull rope 3043 located inside the second bottom cylinder 302 is tightened, and the buckle 3046 on the surface rises accordingly. When the buckle 3046 contacts the support base 3041 fixedly connected to the bottom of the second extension cylinder 3021, it drives the support base 3041, the second extension cylinder 3021, and the already raised heightening cylinder 2032 as a whole to slide synchronously upward along the surface of the second bottom cylinder 302. This second stage of lifting ensures that the workpiece is completely lifted out of the mold cavity.

[0050] During this process, the guide plate 3047, which is fixedly connected to the surface of the first extension cylinder 2031 and the second extension cylinder 3021, guides the movement of the control belt 3048. The control belt 3048, which is fixed to the positioning piece 3045 on the surface of the heightening cylinder 2032 and the support base 3041 on the surface of the second extension cylinder 3021, is lifted as the cylinder is raised. The gravity block 3049 suspended at the end of the control belt 3048 rises, causing the originally loose control belt 3048 to gradually tighten. When the connecting plate 2055 moves upward under the drive of the mechanism, its surface will come into contact with the tightened control belt 3048 and be obstructed.

[0051] The control belt 3048 and the gravity block 3049 are controlled to stop and detach from the connecting plate 2055, thereby achieving pressure changes on the surface of the connecting plate 2055.

[0052] As the mold closing process progresses, the pull rope 3043 slackens, and components such as the riser 2032 and the second extension cylinder 3021 continue to slide downwards under the action of their internal restoring force. This causes the guide plate 3047 and the fixing point of the control belt 3048 to descend synchronously. The downward movement of the fixing point causes the control belt 3048 to completely lose its upward lifting force. Under its own weight, the gravity block 3049 at the end of the suspension drags the entire control belt 3048 down. The slackened control belt 3048 and gravity block 3049 land on the surface of the connecting plate 2055. This process is the reset state, which allows components such as the riser 2032 and the second extension cylinder 3021 to reset without the aid of external force. The upward tendency of the connecting plate 2055 is then suppressed by the combined weight of the control belt 3048 and the gravity block 3049. The movement was forced to stop, resulting in a standstill. When the stamping was completed and the upper die holder 103 rose again to open the die, the disengagement stage was initiated. The pull rope 3043 was tightened again, and the cylinder assembly was driven to rise step by step through the buckle 3046. The fixing point rose accordingly and generated an upward lifting force on the control belt 3048, overcoming the downward pressure of the gravity block 3049. The control belt 3048, which was originally loosely pressed on the connecting plate 2055, was pulled upward as a whole, making it instantly taut into a vertical cable. Thus, it changed from the previous state of weight suppression to the state of obstruction. Although the connecting plate 2055 was freed from direct weight pressure, its upward path was still blocked by this actively established barrier. The shape and position switching of a flexible stop block were controlled, realizing complex programmed control of the actuator movement.

[0053] It is worth noting that during the upward movement of the upper die holder 103, the pull rope 3043 and the buckle 3046 located in the first bottom cylinder 203 drive the lifting cylinder 2032 to rise. The pull rope 3043 and the buckle 3046 located in the second bottom cylinder 302 drive the second extension cylinder 3021 and the lifting cylinder 2032 to rise simultaneously. When the second extension cylinder 3021 and the lifting cylinder 2032 rise to the same height, the stamped workpiece is detached from the punch 104. The pull rope 3043 and the buckle 3046 located in the second bottom cylinder 302 will drive the first extension cylinder 2031 to move upward in the first bottom cylinder 203, so that the raised stamped workpiece slides down the support assembly 305 to the discharge port and then enters the collection area.

[0054] The entire ejection process requires no manual removal, and the hand remains outside the mold at all times, completely eliminating the drawbacks of narrow space, restricted posture, and difficulty in exerting force. The ejection rhythm is completely consistent with the stamping machine, the workpiece is no longer stuck, the surface is free of scratches, the cycle is stable, the mold life is extended, and the operator only needs to remove the part outside the mold. Labor intensity and safety hazards disappear simultaneously.

[0055] The remaining structure is the same as that in Example 1.

[0056] Example 3, referring to Figure 1 - Figure 13 This is the third embodiment of the present invention, which differs from the second embodiment in that: the support assembly 305 includes a support shaft 3044 fixedly connected to the surface of the support base 3041, a discharge plate 3060 rotatably connected to the surface of the support shaft 3044, a fixing strip 3051 fixedly connected to the surface of the discharge plate 3060, a plurality of extension columns 3052 slidably connected to the surface of the fixing strip 3051 and arranged in a linear array, and a shovel plate 3053 fixedly connected to the surface of the extension columns 3052. The shovel plate 3053, with its spring-cushioned design, effectively provides flexible support to the bottom of the workpiece, avoiding rigid contact and friction, thereby protecting the surface quality of the workpiece.

[0057] Compared to Embodiment 2, further, an extrusion column 3054 is fixedly connected to the surface of the extension column 3052, a compression spring 3055 is fixedly connected between the extrusion column 3054 and the fixing strip 3051, and an array plate 3059 is fixedly connected to the surface of the extrusion column 3054. Through the linkage between the gravity sensor 2067 and the control module 3058, the automated triggering of the material discharge process is realized, replacing manual part handling, eliminating safety hazards, and ensuring the accuracy and consistency of the material discharge action.

[0058] Furthermore, a control module 3058 is fixedly connected to the surface of the support base 3041, and an electric base 3056 is fixedly connected to the surface of the support base 3041 and to the side of the control module 3058. A piston rod 3057 is slidably connected to the surface of the electric base 3056, and one end of the piston rod 3057 away from the electric base 3056 is fixedly connected to the surface of the array plate 3059. Through the rotation design of the discharge plate 3060 around the support shaft 3044, the workpiece can automatically slide down the inclined plane by its own gravity, realizing smooth and non-forced discharge, which significantly improves the discharge speed and production cycle.

[0059] During use, the pull rope 3043 and the buckle 3046 mechanism start to work, sequentially driving the lifting cylinder 2032 and the second extension cylinder 3021 to move upward, smoothly lifting the formed workpiece from the punch 104 and causing the workpiece to leave the mold cavity. At the same time, the gravity sensor 2067 continuously monitors the weight change of the integrated cavity bag 2066 and the corrugated soft cone sleeve 2062 system. When the workpiece is fully lifted and the mold is in a safe open state, the weight signal detected by the gravity sensor 2067 reaches the preset threshold, indicating that an effective stamping cycle has been completed.

[0060] At this time, the gravity sensor 2067 immediately generates an electrical signal and sends it to the control module 3058, which is fixedly connected to the surface of the support base 3041. After receiving the signal, the control module 3058 processes the signal internally and then sends a command to the electric base 3056, which is also fixed to the surface of the support base 3041. The electric base 3056 starts, and the working principle of this part is existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here. The piston rod 3057 on its surface starts to perform a precise linear extension movement.

[0061] The top end of the piston rod 3057 is fixedly connected to the surface of the array plate 3059. When the piston rod 3057 moves forward, it directly pushes the array plate 3059 to move in a predetermined direction. The array plate 3059 is fixedly connected to multiple extrusion columns 3054, and each extrusion column 3054 is fixedly connected to an extension column 3052 that is slidably connected to the surface of the fixing strip 3051. The fixing strip 3051 is fixedly installed on the discharge plate 3060. Therefore, the thrust of the piston rod 3057 is transmitted to all the extrusion columns 3054 through the array plate 3059, thereby driving all the extension columns 3052 to slide synchronously and smoothly downwards towards the workpiece under the guidance of the fixing strip 3051.

[0062] When the spade 3053 moves forward under the drive of the extension column 3052, it enters the gap between the bottom of the workpiece and the surface of the discharge plate 3060 during the process. If resistance is encountered, the compression spring 3055 will be compressed. This elasticity ensures that the spade 3053 does not make a hard impact when it contacts the workpiece, but provides a buffered, gradual pressure. This ensures that the spade 3053 can gently support the bottom of the workpiece, thereby greatly avoiding scratches or indentations that may be caused to the workpiece surface by rigid contact and sliding friction. This process realizes the gradual insertion of the bottom of the workpiece per unit time, effectively protecting the surface quality of the workpiece.

[0063] Just after the spade 3053 securely holds the workpiece, the mold opening action continues. As the upper mold base 103 continues to rise, the pull rope 3043 and the buckle 3046 located in the second bottom cylinder 302 will further drive the first extension cylinder 2031 to move upward along the first bottom cylinder 203. Since the support base 3041 is fixedly connected to the surface of the second extension cylinder 3021, and the support shaft 3044 is fixed to the support base 3041, the ejector plate 3060 is rotatably connected to the support base 3041 through the support shaft 3044. When the second extension cylinder 3021 and the raising cylinder 2032 are synchronously raised to the same height under the traction of the pull rope 3043 and the buckle 3046, the stamped workpiece is completely separated from the surface of the punch 104. Immediately afterwards, the first extension cylinder 2031 located in the second bottom cylinder 302... The pull rope 3043 and the buckle 3046 mechanism inside the cylinder 302 continue to act as a barrier, driving the first extension cylinder 2031 to move upward along the track of the first bottom cylinder 203. The discharge plate 3060 drives the shovel plate 3053 to rotate on the surface of the support shaft 3044, causing the workpiece on the surface of the shovel plate 3053 and the discharge plate 3060 to slide along the inclined surface of the discharge plate 3060. The workpiece smoothly slides down the slope and finally enters the preset collection area through the discharge port.

[0064] The remaining structure is the same as that in Example 2.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
