By relying on multiple automotive parts stacked on the temporary storage plate, the temporary storage plate slides down with the weight of the stacked automotive parts, reducing the serious impact and wear caused by the height difference when multiple automotive parts are stacked. When the temporary storage plate slides down, it drives the pressure plate to trigger the pressure sensor. After the pressure sensor is triggered, it sends a signal to warn of material collection, which plays a role in reminding to collect when there is too much material. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 3 As shown in the embodiment of the present invention, a stamping die includes a die body 1; a stamping groove 11 is formed at the end of the die body 1; a stamping press base 12 is fixedly connected to the outside of the die body 1; a sliding block 13 is slidably connected to the inner wall of the die body 1; a stamping assembly is provided on the stamping press base 12, which is used to cooperate with the die body 1 to stamp automotive parts; an ejection assembly is provided inside the stamping press base 12, which is used to eject the automotive parts stamped in the stamping groove 11; when stamping automotive parts, the automotive parts are first formed... The raw material for the component is placed at the end of the mold body 1. The stamping base 12 serves as the main structure of the stamping equipment. The stamping assembly is used to stamp the raw material on the mold body 1. The raw material is pressed into the stamping groove 11 and is located at the end of the sliding block 13. The raw material is stamped into automotive parts. Then the stamping assembly is reset, and the ejection assembly, together with the sliding block 13, pushes the stamped automotive parts onto the mold body 1. The automotive parts are ejected from the stamping groove 11 and out of the mold body 1, which facilitates the quick removal of the formed automotive parts and improves the efficiency of automotive parts stamping production.

[0029] A controller 2 is installed on the outside of the stamping press base 12; the ejection assembly includes an electric cylinder 21 and an ejector rod 22; the electric cylinder 21 is fixed inside the stamping press base 12 and is located below the sliding block 13, and the electric cylinder 21 is electrically connected to the controller 2; the ejector rod 22 is fixed to the output end of the electric cylinder 21; when ejecting the automotive parts formed in the stamping groove 11, the controller 2 controls the output end of the electric cylinder 21 to extend, driving the ejector rod 22 inserted into the bottom end of the sliding block 13 to push upward, which can eject the automotive parts on the sliding block 13 out of the stamping groove 11, thereby facilitating the rapid removal of automotive parts.

[0030] like Figure 1 As shown, the stamping assembly includes a hydraulic cylinder 3 and a stamping block 31; the hydraulic cylinder 3 is fixedly connected to the stamping machine base 12 and is located above the mold body 1, and the hydraulic cylinder 3 is electrically connected to the controller 2; the stamping block 31 is fixedly connected to the output end of the hydraulic cylinder 3; when stamping the raw material of the automobile parts, the raw material of the automobile parts is first placed at the end of the mold body 1, and the controller 2 controls the output end of the hydraulic cylinder 3 to extend downward, directly driving the stamping block 31 to stamp the raw material of the automobile parts on the mold body 1, thereby playing the role of stamping and forming the automobile parts.

[0031] like Figures 1 to 3 As shown, the sliding block 13 has an extrusion chamber 41 inside; an extrusion plate 4 is slidably connected inside the extrusion chamber 41, and the bottom end of the extrusion plate 4 is fixedly connected to the end of the push rod 22; multiple atomizing nozzles 42 are fixedly connected to the outside of the sliding block 13; two one-way valves 43 are fixedly connected to both sides of the sliding block 13 near the extrusion chamber 41; a storage component is provided inside the mold body 1, which is used to temporarily store the release agent; when the automotive parts are stamped and removed, the formed automotive parts are tightly attached to the inner wall of the stamping groove 11, affecting demolding. The release agent stored inside the storage component is used to demold the parts. The release agent is delivered to the extrusion chamber 41 through two one-way valves 43. The two one-way valves 43 are designed for one-way channels, which can only deliver the release agent and will not discharge it. Some of the release agent is temporarily stored on the extrusion plate 4. As the output end of the electric cylinder 21 drives the push rod 22 to push up, the push rod 22 can lift the extrusion plate 4 and squeeze the release agent inside the extrusion chamber 41. The sliding block 13 is pushed up and slides on the inner wall of the mold body 1 until the multiple atomizing nozzles 42 are located at the stamping groove 11. The release agent is sprayed out by the multiple atomizing nozzles 42 and sprayed on the inner wall of the stamping groove 11, which is conducive to the rapid demolding after the next automotive part is stamped.

[0032] The storage component includes a storage box 5 and a flow cavity 51; the storage box 5 is fixed inside the mold body 1; the flow cavity 51 is opened inside the mold body 1, and the storage box 5 can be connected to the one-way valve 43 through the flow cavity 51; when the release agent is sprayed on the stamping groove 11, the release agent is pre-injected into the storage box 5, and the release agent in the storage box 5 is guided from high to low through the flow cavity 51. The guided release agent flows into the extrusion chamber 41 from the one-way valve 43. As the extrusion plate 4 extrudes the release agent temporarily stored in the extrusion chamber 41, it is atomized and sprayed onto the stamping groove 11, which plays the role of storing and guiding the release agent.

[0033] A sliding plate 6 is slidably connected inside the mold body 1; a first sealing block 61 is fixedly connected to the end of the sliding plate 6; a second sealing block 62 is fixedly connected to the side of the end of the sliding plate 6 away from the first sealing block 61, and overflow holes are staggered on the first sealing block 61 and the second sealing block 62; a transmission assembly is provided on the outside of the ejector rod 22, which is used to drive the sliding plate 6 to slide; when the release agent in the storage box 5 flows down, the transmission assembly slides up with the ejector rod 22 when demolding the molded automotive parts, and the release agent temporarily stored between the first sealing block 61 and the second sealing block 62 will flow into the extrusion chamber 41 in advance, at which time the overflow hole of the first sealing block 61 and the second sealing block 62 will flow into the extrusion chamber 41 in advance, and ... will flow into the extrusion chamber 41 in advance, and the overflow hole of the first sealing block 61 will flow into the extrusion chamber 41 in advance, and the overflow hole of the first sealing block 61 will flow into the extrusion chamber 41 in advance, and the overflow hole of the first sealing block 61 will flow into the extrusion chamber 41 in advance, and the overflow hole of the first sealing block 61 will flow into the extrusion chamber 41 in advance, and the overflow hole of the first sealing block The flow chambers 51 are staggered and blocked, and the overflow hole of the second blocking block 62 is connected to the flow chamber 51. The transmission component slides upward with the push rod 22, causing the sliding plate 6 to slide. The first blocking block 61 and the second blocking block 62 slide upward synchronously with the sliding plate 6. At this time, the overflow hole of the first blocking block 61 is connected to the flow chamber 51, while the overflow hole of the second blocking block 62 is staggered with the flow chamber 51 and blocks the flow chamber 51. The release agent in the storage box 5 flows through the flow chamber 51 to the second blocking block 62 for temporary storage. When the sliding plate 6 is reset, the release agent temporarily stored in the second blocking block 62 will enter the extrusion chamber 41 to wait for another extrusion and spraying, which plays the role of quantitative control of the release agent spraying.

[0034] The transmission assembly includes a fixed frame 7 and a top plate 71; the fixed frame 7 is fixed to the outer wall of the push rod 22; both top plates 71 are fixed to the two ends of the fixed frame 7; the mold body 1 has two sliding cavities 72 inside, and the sliding cavities 72 are correspondingly arranged with the top plates 71; when the flow cavity 51 is blocked, the output end of the electric cylinder 21 drives the push rod 22 to push upward, the push rod 22 drives the fixed frame 7 fixed to the outer wall to slide upward, and the two top plates 71 on the fixed frame 7 slide upward synchronously and insert into the two sliding cavities 72 until the top plate 71 pushes the sliding plate 6 upward and drives the first blocking block 61 and the second blocking block 62 to slide, thereby enabling the flow cavity 51 to be blocked.

[0035] like Figure 1 , Figure 4 and Figure 5As shown, a fixed base 8 is fixedly connected to the outside of the stamping press base 12; an electric slider 81 is slidably connected to the end of the fixed base 8; a support frame 82 is fixedly connected to the end of the electric slider 81; a servo motor 83 is fixedly connected to the end of the support frame 82; a clamping plate 84 is slidably connected to the outer wall of the support frame 82 near the servo motor 83; a lead screw 85 is fixedly connected to the output end of the servo motor 83, and the lead screw 85 is connected to the lead screw nut pair of the clamping plate 84; when the automotive parts are stamped and formed, the sliding block 13 pushes the automotive parts out of the mold body 1. Inside, the fixed seat 8 is fixed to the outer side of the stamping machine base 12. The electric slider 81 drives the support frame 82 to slide on the fixed seat 8. Then, the output end of the servo motor 83 drives the lead screw 85 to rotate in the forward direction, and the distance between the clamping plate 84 and the servo motor 83 increases. After one side of the car part is placed above the clamping plate 84, the output end of the servo motor 83 drives the lead screw 85 to rotate in the reverse direction, so that the clamping plate 84 and the support frame 82 clamp the car part. As the electric slider 81 slides and resets, it plays the role of automatically picking up the stamped car parts.

[0036] The end of the fixed base 8 is fixedly connected to a collection box 9; a temporary storage plate 91 is slidably connected to the inner wall of the collection box 9; an elastic element 92 is fixedly connected to the bottom end of the temporary storage plate 91; when the stamped automotive parts are being removed, the clamping plate 84 cooperates with the support frame 82 to clamp the ejected automotive parts. As the electric slider 81 drives the clamped automotive parts to slide above the collection box 9, the automotive parts are placed on the temporary storage plate 91 and located in the collection box 9, which serves to store the automotive parts. Whenever an automotive part is placed on the temporary storage plate 91, the temporary storage plate 91 will press against the elastic element 92 and contract and slide down, and multiple automotive parts will be stacked in the collection box 9, reducing the serious impact and wear caused by the height difference when multiple automotive parts are stacked.

[0037] A fixing block 93 is fixedly connected inside the collection box 9; a pressing rod 94 is slidably connected to the inner wall of the fixing block 93, and a spring is sleeved on the pressing rod 94; a pressure plate 95 is fixedly connected to the bottom end of the pressing rod 94, and the pressure plate 95 is located inside the fixing block 93; a pressure sensor 96 is installed inside the fixing block 93 and below the pressure plate 95; when multiple automotive parts are stacked, the multiple automotive parts stacked on the temporary storage plate 91 continuously press down on the elastic element 92 due to gravity and contract until the temporary storage plate 91 slides down and presses down on the pressing rod 94. The pressing rod 94 drives the pressure plate 95 to slide down, the spring on the pressing rod 94 contracts and is forced, the pressure plate 95 slides down and triggers the pressure sensor 96, and the pressure sensor 96 sends a signal to warn that there is too much material stored in the collection box 9, notifying the staff to come and collect the material, which serves to remind people to collect the material when there is too much material.

[0038] Working process: When stamping automotive parts, the raw material for the automotive parts is first placed at the end of the mold body 1. The stamping press base 12, as the main structure of the stamping equipment, uses the stamping assembly to stamp the raw material on the mold body 1. The raw material is pressed into the stamping groove 11 and located at the end of the sliding block 13, stamping the raw material into automotive parts. Subsequently, the stamping assembly is reset, and the ejector assembly, in conjunction with the sliding block 13, pushes the stamped automotive parts upward, ejecting the automotive parts from the stamping groove 11 into the mold body 1. This facilitates rapid unloading of the formed automotive parts, thereby improving the efficiency of automotive parts processing. The efficiency of stamping production is improved. When the automotive parts formed in the stamping groove 11 are ejected, the controller 2 controls the output end of the electric cylinder 21 to extend, which drives the push rod 22 inserted into the bottom of the sliding block 13 to push up, thus ejecting the automotive parts on the sliding block 13 out of the stamping groove 11, thereby facilitating the quick removal of automotive parts. When stamping the raw material of automotive parts, the raw material of automotive parts is first placed at the end of the mold body 1, and the controller 2 controls the output end of the hydraulic cylinder 3 to extend downward, directly driving the stamping block 31 to stamp the raw material of automotive parts on the mold body 1, thereby playing the role of stamping and forming automotive parts.

[0039] When the stamped automotive parts are removed from the mold, the parts adhere tightly to the inner wall of the stamping groove 11, affecting demolding. A storage component stores the release agent, which is then delivered to the extrusion chamber 41 through two one-way valves 43. These valves 43 are one-way channels, allowing only the release agent to be delivered and not discharged. Some release agent is temporarily stored on the extrusion plate 4. As the output of the electric cylinder 21 drives the push rod 22 upwards, the push rod 22 lifts the extrusion plate 4, squeezing the release agent inside the extrusion chamber 41. The sliding block 13 is pushed upwards and slides against the inner wall of the mold body 1 until multiple atomizing nozzles 42 are positioned at the stamping groove 11. At this point, the release agent is sprayed from the atomized nozzles 42 onto the stamping groove 11. The inner wall of 1 facilitates rapid demolding after the next automotive part is stamped; when the release agent is sprayed on the stamping groove 11, the release agent is pre-injected into the storage box 5. The release agent in the storage box 5 flows from high to low through the flow cavity 51. The guided release agent flows into the extrusion cavity 41 from the one-way valve 43. As the extrusion plate 4 squeezes the release agent temporarily stored in the extrusion cavity 41, it is atomized and sprayed onto the stamping groove 11, which plays the role of storing and guiding the release agent; when the release agent in the storage box 5 flows down, the transmission component slides upward with the ejector rod 22 when demolding the formed automotive part. The release agent temporarily stored between the first sealing block 61 and the second sealing block 62 will flow into the extrusion cavity 41 in advance. At this time, the first sealing block 61 The overflow hole of the first sealing block 61 is intersected with and blocks the flow cavity 51, while the overflow hole of the second sealing block 62 is connected to the flow cavity 51. The transmission assembly slides upward with the push rod 22, causing the sliding plate 6 to slide. The first sealing block 61 and the second sealing block 62 slide upward synchronously with the sliding plate 6. At this time, the overflow hole of the first sealing block 61 is connected to the flow cavity 51, while the overflow hole of the second sealing block 62 is intersected with and blocks the flow cavity 51. The release agent in the storage box 5 flows through the flow cavity 51 to the second sealing block 62 for temporary storage. When the sliding plate 6 is reset, the release agent temporarily stored at the second sealing block 62 will enter the extrusion cavity 41 to wait for another extrusion and spraying, which plays the role of quantitative control of the release agent spraying. When the flow cavity 51 is controlled... When sealing, the output end of the electric cylinder 21 drives the push rod 22 to push upward. The push rod 22 drives the fixed frame 7 fixed to the outer wall to slide upward. The two top plates 71 on the fixed frame 7 slide upward simultaneously and insert into the two sliding cavities 72 until the top plate 71 pushes the sliding plate 6 upward and drives the first sealing block 61 and the second sealing block 62 to slide, thereby controlling the sealing at the flow cavity 51. When controlling the sealing at the flow cavity 51, the output end of the electric cylinder 21 drives the push rod 22 to push upward. The push rod 22 drives the fixed frame 7 fixed to the outer wall to slide upward. The two top plates 71 on the fixed frame 7 slide upward simultaneously and insert into the two sliding cavities 72 until the top plate 71 pushes the sliding plate 6 upward and drives the first sealing block 61 and the second sealing block 62 to slide, thereby controlling the sealing at the flow cavity 51.

[0040] When the stamped automotive parts are being unloaded, the sliding block 13 ejects the automotive parts from the interior of the mold body 1. The fixed seat 8 is fixed to the outside of the stamping machine base 12. The electric slider 81 drives the support frame 82 to slide on the fixed seat 8. Then, the output end of the servo motor 83 drives the lead screw 85 to rotate in the forward direction, increasing the distance between the clamping plate 84 and the servo motor 83. After one side of the automotive parts is placed above the clamping plate 84, the output end of the servo motor 83 drives the lead screw 85 to rotate in the reverse direction, so that the clamping plate 84, together with the support frame 82, clamps the automotive parts. As the electric slider 81 slides back to its original position, it automatically unloads the stamped automotive parts. When unloading the stamped automotive parts, the clamping plate 84, together with the support frame 82, clamps the ejected automotive parts. As the electric slider 81 drives the clamped automotive parts to slide above the collection box 9, the unloaded parts slide to the top of the collection box 9. The vehicle parts are placed on the temporary storage plate 91 and located in the collection box 9, serving as a storage device for the vehicle parts. Whenever a vehicle part is placed on the temporary storage plate 91, the temporary storage plate 91 will press down on the elastic element 92 and slide down, allowing multiple vehicle parts to be stacked in the collection box 9. This reduces the risk of severe impact and wear due to height differences when multiple vehicle parts are stacked. When multiple vehicle parts are stacked, the multiple vehicle parts stacked on the temporary storage plate 91 continuously press down on the elastic element 92 due to gravity until the temporary storage plate 91 slides down and presses down on the compression rod 94. The compression rod 94 drives the pressing plate 95 to slide down, and the spring on the compression rod 94 contracts under force. The sliding of the pressing plate 95 triggers the pressure sensor 96, which sends a signal to warn that there is too much material stored in the collection box 9, notifying the staff to collect the material. This serves as a reminder to collect the material when there is too much material.
