Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a stamping demolding and ejection device for automotive parts. Background Technology

[0002] Stamping of automotive parts is one of the core processes in automobile manufacturing. It applies external force to metal sheets through molds and presses, causing them to plastically deform or separate, thereby obtaining high-precision, high-strength, and lightweight parts. The stamping device is the core equipment for realizing metal plastic forming in automobile manufacturing. Through the synergistic action of molds and presses, it applies external force to metal sheets, causing them to plastically deform or separate, thereby precisely manufacturing parts with complex shapes.

[0003] After the parts are stamped, the metal sheet is ejected by the demolding mechanism to demold the metal sheet. However, after demolding, it is necessary to manually or with a specific fixture to reach into the stamping device to remove the metal sheet and install a new metal sheet to be stamped. The action of the upper mold is automatically controlled by the hydraulic pump. The operation time window is short, and the speed of manual operation is difficult to match the high-speed stamping cycle, which poses a safety hazard and is prone to causing safety accidents.

[0004] Therefore, this application provides a stamping demolding and ejection device for automotive parts to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a stamping demolding and ejection device for automotive parts, which solves the problem that existing stamping devices require manual removal of parts, which poses a certain degree of danger.

[0006] To solve the above-mentioned technical problems, this utility model provides a stamping demolding and ejection device for automotive parts, including a base, a plurality of support columns on the base, a support plate on the top of the support columns, a lower die on the upper surface of the base body, an upper die adapted above the lower die, and the upper die being located on the lower side of the support plate; a support frame is provided on one side of the lower die, and a pushing mechanism is provided on the support frame. The pushing mechanism is slidably connected to a drive mechanism, which is located on the support plate. The drive mechanism is linked to the pushing mechanism to push the stamped parts away from the working area.

[0007] A further improvement of the present invention is that the driving mechanism includes an electric cylinder mounted on the upper surface of the support plate, the telescopic push rod of the electric cylinder passes through the support plate, an active slider is mounted at the bottom end of the telescopic push rod, and matching sliding columns are symmetrically mounted on both sides of the active slider.

[0008] A further improvement of the present invention is that the driving mechanism includes two symmetrically arranged driven plates, each driven plate having a T-shaped component at its bottom. The T-shaped component is adapted to a limiting slide groove, which is symmetrically arranged on the upper surface of the support frame.

[0009] A further improvement of this utility model is that: matching grooves are opened on the opposite sides of the two driven plates, and matching sliding columns are slidably connected in the matching grooves.

[0010] A further improvement of this utility model is that the two mating grooves are parallel and the mating grooves are inclined, with the mating grooves inclined upward at 45° in the direction away from the lower mold.

[0011] A further improvement of this utility model is that a connecting rod is provided on the side of the driven plate, and a pushing block is provided on the end face of the connecting rod.

[0012] A further improvement of this utility model is that: support sliders are symmetrically arranged on the lower surface of the push block, and cleaning blocks are also symmetrically arranged on the lower surface of the push block.

[0013] A further improvement of this utility model is that the support slider is adapted to slide within the support groove, and the support groove is symmetrically opened on the upper surface of the lower mold body.

[0014] A further improvement of this utility model is that a collection hole is also provided in the middle of the upper surface of the lower mold body, which is used to collect the waste generated after the parts are processed.

[0015] A further improvement of this utility model is that a hydraulic pump is provided on the upper surface of the support plate, and the output end of the hydraulic pump passes through the support plate and is adapted to the upper mold.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. The present invention provides a stamping demolding and ejection device for automotive parts. By starting an electric cylinder, a telescopic push rod is driven to rotate. Through threaded engagement, the active slider moves upward. As the active slider continues to move upward, the sliding of the mating sliding pins on both sides within the mating groove drives the driven plate to move towards the part. The driven plate, through a connecting rod, drives the push block to move together, thereby ejecting the part. This eliminates the need for manual removal of the part from the stamping device and reduces safety hazards during the removal process.

[0018] 2. The present invention provides a stamping demolding and ejection device for automotive parts, which drives the driven plate to move by the cooperation between the sliding pillars on both sides of the active slider and the sliding groove on the side of the driven plate, making the entire ejection process more stable.

[0030] The present invention will be further explained below with reference to specific embodiments.

[0031] like Figures 1-2As shown, in this embodiment, a stamping demolding and ejection device for automotive parts includes a base 1, a plurality of support columns 12 on the base 1, a support plate 2 on the top of the support columns 12, a lower die 5 on the upper surface of the base 1 body, and an upper die 3 vertically fitted above the lower die 5, the upper die 3 being positioned below the support plate 2; a support frame 6 is provided on the horizontal side of the lower die 5 body, a pushing mechanism 7 is provided on the support frame 6, the pushing mechanism 7 is slidably connected to the active slider 803 in the drive mechanism 8, the drive mechanism 8 is mounted through the support plate 2, and the drive mechanism 8 pushes the stamped parts away from the stamping area through the telescopic linkage of the push mechanism 7; specifically, a plurality of support columns 12 are provided on the base 1, a support plate 2 is provided on the top of the support columns 12, a lower die 5 is provided on the upper surface of the base 1 body, and an upper die 3 is vertically fitted above the lower die 5, the upper die 3 being positioned below the support plate 2; a support frame 6 is provided on the horizontal side of the lower die 5 body, a pushing mechanism 7 is provided on the support frame 6, the pushing mechanism 7 is slidably connected to the active slider 803 in the drive mechanism 8, the drive mechanism 8 is mounted through the support plate 2, and the drive mechanism 8 pushes the stamped parts away from the stamping area through telescopic linkage of the push mechanism 7; specifically, a plurality of support columns 12 are provided on the base 1, a support plate 2 is provided on the top of the support columns 12 ... The upper die 3 is set on the underside of the support plate 2. A hydraulic pump 4 is set on the upper surface of the support plate 2. The hydraulic pump 4 works with other hydraulic components to control the up and down movement of the upper die 3. The output end of the hydraulic pump 4 passes through the support plate 2 and is connected to the upper die 3. A support frame 6 is set on one side of the lower die 5. A pushing mechanism 7 is set on the support frame 6. The pushing mechanism 7 is slidably connected to the driving mechanism 8. The driving mechanism 8 is set on the support plate 2. The driving mechanism 8 is linked with the pushing mechanism 7 to push the stamped parts away from the working area. Before stamping, the parts are rectangular metal sheets with a length much greater than the length of a single part. When stamping the parts, the upper die 3 will cut the metal sheet at the same time. After the stamping of a single part is completed, the metal sheet is pushed towards the lower die 5 to achieve rapid feeding.

[0032] like Figures 2-4 As shown, the drive mechanism 8 includes an electric cylinder 801 mounted on the upper surface of the support plate 2. A telescopic push rod 802 is mounted at the output end of the electric cylinder 801, passing through the support plate 2. An active slider 803 is mounted at the bottom end of the telescopic push rod 802. Symmetrical sliding columns 804 are mounted on both sides of the active slider 803. The push mechanism 7 includes two symmetrically arranged driven plates 701. T-shaped members 707 are mounted on the bottom of each driven plate 701. The T-shaped members 707 fit into limiting grooves 11, thus confining the driven plates 701 within the limiting grooves 11. Limiting grooves 11 are symmetrically arranged on the upper surface of the support frame 6. Matching grooves 704 are also opened on the opposite sides of the two driven plates 701. Matching sliding columns 804 are slidably connected in the matching grooves 704. The two matching grooves 704 are parallel and the matching grooves 704 are inclined. The matching grooves 704 are inclined upward at 45° away from the lower mold 5, so as to ensure that the matching grooves 704 are evenly stressed and the movement of the driven plates 701 in the horizontal direction is stable. A connecting rod 702 is provided on the side of the driven plate 701, and a pushing block 703 is provided on the end face of the connecting rod 702.

[0033] like Figures 5-6As shown, a support slider 705 is symmetrically arranged on the lower surface of the push block 703, and a cleaning block 706 is also symmetrically arranged on the lower surface of the push block 703. The cleaning block 706 is located inside the support slider 705. The cleaning block 706 cleans up the waste generated during the stamping process and allows the waste to enter the lower die 5, thereby saving resources. A support groove 9 is symmetrically opened on the upper surface of the lower die 5 body, and the support slider 705 is slidably arranged on the upper surface of the support groove 9. The lower die 5 has a built-in ejection mechanism for demolding the completed parts. A collection hole 10 is also opened in the middle of the upper surface of the lower die 5 body for collecting the waste generated after the parts are processed.

[0034] The working principle of the technical solution provided by this utility model is as follows:

[0035] When using the device, the user first places the metal sheet to be stamped on the lower die 5, and then controls the upper die 3 at its bottom to move downward by starting the hydraulic pump 4. Through the cooperation of the upper die 3 and the lower die 5, the metal sheet is stamped, thereby forming a single part. During this process, the waste generated by stamping enters the lower die 5 through the collection hole 10 and falls into the waste material frame.

[0036] After the parts are demolded, the electric cylinder 801 is activated to drive the telescopic push rod 802 at the output end to shorten upward. At this time, the telescopic push rod 802 drives the active slider 803 to move upward at a constant speed. The mating slide pins 804 on both sides of the active slider 803 slide in the mating slide groove 704, thereby driving the two driven plates 701 to move towards the parts. At the same time, the driven plates 701 drive the push block 703 to move in the same direction through the connecting rod 702, thereby causing the push block 703 to push the parts away from the working area. Meanwhile, the cleaning block 706 at the bottom of the push block 703 cleans the waste around the parts after stamping and pushes the waste into the collection hole 10.

[0037] After the work area for ejecting the parts is completed, the electric cylinder 801 is activated in the reverse direction, which drives the telescopic push rod 802 to extend downward, causing the active slider 803 to move downward at a constant speed. This, in turn, drives the driven plate 701 away from the parts through the sliding column 804. The driven plate 701, through the connecting rod 702, drives the push block 703 to move in the same direction, completing the overall reset. At the same time, the metal sheet is pushed to the lower die 5 to realize the feeding of the next stamping process. At this time, the hydraulic pump 4 is activated again to complete the entire cycle.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
