A hot stamping device for plastic product production

Abstract

The present invention relates to the technical field of plastic product production, and in particular to a hot stamping device for the production of plastic products. The technical problem is that the electroplated aluminum is in a tense state when placed, which causes wrinkles to appear on the electroplated aluminum. When the wrinkles appear on the electroplated aluminum and then hot stamping is performed, creases or missing patterns will appear, resulting in unqualified products. The technical solution of the present invention is: a hot stamping device for the production of plastic products, including a workbench and a mounting frame, etc.; a mounting frame is provided on each side of the workbench. The two first guide rails drive the two first moving blocks connected thereto to move in opposite directions, so that the first moving block drives the connecting block and its related parts to move. When the connecting block moves, the second connecting plate pushes the electroplated aluminum to both sides to make it flat, and the scraper can scrape off the dust particles attached to the convex surface, and the push plate will push the electroplated aluminum downward to make it fit the convex surface.

Description

Technical Field

[0001] The present invention relates to the technical field of plastic product production, in particular to a hot stamping device for plastic product production. Background Art

[0002] When hot stamping a plastic curved plate, due to the bulge in the middle of the curved plate, it is necessary to first place the electroplated aluminum on the curved plate and then use the hot stamping equipment to perform hot stamping.

[0003] Since the anodized aluminum needs to be sent out of the unprinted part and the printed part needs to be rolled up through the winding equipment, the anodized aluminum needs to be in a relatively tight state to prevent slipping during rolling. When the anodized aluminum is placed on the curved plate, the middle of the curved plate is bulged, which causes the middle part of the anodized aluminum to be blocked first, making the anodized aluminum itself even tighter, resulting in wrinkles on the anodized aluminum. When the anodized aluminum is wrinkled and then hot-stamped, it will cause creases or missing patterns, resulting in unqualified products.

[0004] When the curved plate to be hot stamped has two curved surfaces, such as Figure 16 As shown, if the curvature of the curved surface is different, direct hot stamping will make the electroplated aluminum unable to fit, and then hot stamping needs to be done twice. In addition, the existing manual operation leads to low hot stamping efficiency and slow production efficiency.

[0005] Before hot stamping, the curved plate needs to be cleaned on the surface to be stamped, and the attached dust and other particles need to be wiped off to keep the stamping surface clean. This prevents dust particles from being stamped into the pattern during stamping, resulting in low product quality. The existing technology uses manual cleaning, which is prone to omissions and other problems. Summary of the Invention

[0042] The pushing unit includes a first connecting plate 129 and a pushing plate 1210. The telescopic parts of the two third push rods 128 on the same side are fixedly connected to a first connecting plate 129. Each first connecting plate 129 is connected to a pushing plate 1210 via a torsion spring shaft.

[0043] The cleaning unit includes a second connecting plate 131 and a scraper 132. Two connecting blocks 127 with the front and rear sides on the same side are screwed together to form a second connecting plate 131. Each second connecting plate 131 is connected to a scraper 132 via a torsion spring.

[0044] The specific working steps are:

[0045] Before working, the worker first places the first curved plate 100 and the second curved plate 200 into the left part of the first slide 6 with the two convex sides attached. Figure 2 As shown in the state, the motor 102 is controlled to drive the gear 103 to rotate clockwise from the perspective of front to back, so that the gear 103 drives the rack 104 to move to the right, and then drives the first slider 6 to move to the right through the rack 104, and then drives the first curved plate 100 and the second curved plate 200 to move to the right below the stamping mechanism 3 through the first slider 6, and then the four first push rods 112 on the left push the two limit blocks 113 on the left and related parts to move downward, so that the limit blocks 113 clamp the edges of the first curved plate 100 and the second curved plate 200, as shown in FIG. Figure 3 In the state shown, when the limit block 113 drives the first clamping plate 122 and the push plate 1210 to descend, since the first clamping plate 122 and the push plate 1210 are located above the electroplated aluminum that has been unfolded by the automatic winder 5, when the first clamping plate 122 and the push plate 1210 descend, they will push the electroplated aluminum to move downward, causing the electroplated aluminum to descend above the second connecting plate 131, and then the second push rod 121 pushes the first clamping plate 122 to descend, causing the first clamping plate 122 to push the two sides of the electroplated aluminum to move downward again, and since the middle of the electroplated aluminum is in contact with the upper part of the second connecting plate 131, when the two sides of the electroplated aluminum descend, the middle of the electroplated aluminum will not move, so that the middle of the electroplated aluminum is higher and the two sides are lower, so that the electroplated aluminum fits the convex surface shape, and at the same time as the two sides of the electroplated aluminum descend, the third push rod 128 drives the first connecting plate 129 to descend, so that the first connecting plate 129 drives the push rod 128 to push the The plate 1210 descends, causing the push plate 1210 to push the middle part of the anodized aluminum downward again. Due to the obstruction of the second connecting plate 131, the middle part of the anodized aluminum will be in an M shape, so that the anodized aluminum is completely in contact with the two scrapers 132. Then, the two first guide rails 125 drive the two first moving blocks 126 connected thereto to move in opposite directions, so that the first moving blocks 126 drive the connecting block 127 and its related parts to move. When the connecting block 127 drives the second connecting plate 131 to move, since the second connecting plate 131 is provided with a pushing groove 131a, and the anodized aluminum is in close contact with the second connecting plate 131, when the second connecting plate 131 moves, the pushing groove 131a will smooth the anodized aluminum to the left and right sides, and the scraper 132 can scrape off the dust particles attached to the convex surface, and the push plate 1210 will push the anodized aluminum downward to make it in contact with the convex surface.

[0046] It should be noted that when the push plate 1210 and the scraper 132 descend and contact the convex surface, they will rotate, so that the push plate 1210 and the scraper 132 are in close contact with the convex surface. When the convex surface moves, the rebound force of the torsion spring keeps the push plate 1210 and the scraper 132 in close contact with the convex surface, thereby achieving the adjustment according to the arc surface of the convex surface, and then the anodized aluminum can be fitted according to the curvature of the arc surface;

[0047] When the two push plates 1210 and the scraper 132 move back to back to the front and rear of the first curved plate 100 and the second curved plate 200, the stamping mechanism 3 is controlled to descend to stamp the electroplated aluminum into the convex surfaces of the first curved plate 100 and the second curved plate 200, and then the stamping mechanism 3 is controlled to return to its original position, and then the push plates 1210 and the scraper 132 and other parts are controlled to return to their original positions, but the limit block 113 will continue to clamp the first curved plate 100 and the second curved plate 200.

[0048] Example 2: Based on Example 1, Figure 7-9 As shown, it also includes a pushing component. The two right support plates 4 are commonly connected to a pushing component for pushing the stamped second curved plate 200 and the third curved plate 300 to move to the right. The pushing component includes a clamping block 201 and a moving unit; the two rear limit blocks 113 are commonly connected to a moving unit; the moving unit is connected to the two clamping blocks 201, and the two clamping blocks 201 are driven to move forward, backward, left and right through the moving unit.

[0049] The moving unit includes a first fixed plate 211, a second guide rail 212, a second moving block 213, a third fixed block 214 and a fourth push rod 215; the two rear limit blocks 113 are each fixedly connected to a first fixed plate 211; each first fixed plate 211 is each fixedly connected to a second guide rail 212; each second guide rail 212 is each slidingly connected to a second moving block 213; each second moving block 213 is each fixedly connected to a third fixed block 214; each third fixed block 214 is each fixedly connected to a fourth push rod 215; the telescopic part of each fourth push rod 215 is each connected to a clamping block 201.

[0050] The working steps are:

[0051] After the first curved plate 100 and the second curved plate 200 are processed, the motor 102 drives the gear 103 to rotate counterclockwise from the perspective of looking from the front to the back, so that the gear 103 drives the rack 104 and the first slider 6 to move to the left, so that the left part of the first slider 6 moves to the left end of the workbench 1 again, and the first curved plate 100 and the second curved plate 200 are clamped by the limit block 113, so as to remain in place and remain motionless, and then the third curved plate 300 and the fourth curved plate 400 are placed on the left part of the first slider 6, and then the first push rod 112 pushes the limit block 113 upward, so that the limit block 113 no longer limits the first curved plate 100 and the second curved plate 200, and then the automatic rewinder 5 rewinds the hot-stamped electroplated aluminum and sends out the new electroplated aluminum. At the same time, the first slider 6 is pushed again to drive the third curved plate 300 and the fourth curved plate 400 and the first curved plate 100 and the second curved plate 200 to move to the right synchronously, and then the first curved plate 100 is taken out, so that the concave surfaces of the second curved plate 200 and the third curved plate 300 are subsequently hot-stamped together, as shown in FIG. Figure 7 In the state shown, the third curved plate 300 and the fourth curved plate 400 are moved to the bottom of the limit block 113, and then the third curved plate 300 and the fourth curved plate 400 are hot stamped. At this time, the worker takes out the first curved plate 100, and then again clamps the third curved plate 300 and the fourth curved plate 400 with the limit block 113 and controls the first slider 6 to move to the left. At this time, the second curved plate 200 will move to the left together with the first slider 6, so that the second curved plate 200 The left side is fitted with the right side of the limit block 113, so that the second curved plate 200 and the third curved plate 300 maintain a certain distance, and then two new curved plates are put in again, and then the third curved plate 300 and the fourth curved plate 400 are released, and then the first slider 6 drives all the curved plates above it to move to the right, and the newly placed curved plate will move to the bottom of the limit block 113 again and be hot stamped, and the third curved plate 300 after the movement will be at a certain distance from the second curved plate 200, as shown in FIG. Figure 8As shown in the state, the two fourth push rods 215 then push the two clamping blocks 201 to move toward each other. When the clamping blocks 201 move, they push the third curved plate 300 and the second curved plate 200 to both sides. Then, the two clamping blocks 201 clamp the third curved plate 300 and the second curved plate 200, so that the distance between the third curved plate 300 and the second curved plate 200 is the length of the protruding portion of the clamping blocks 201. Then, the second guide rail 212 drives the second moving block 213 to drive the third fixed block 214 to move to the right, so that the third fixed block 214 drives the fourth push rod 215, the clamping blocks 201 and the clamped third curved plate 300 and the second curved plate 200 moves to the right and under the rear limit block 113, and at this time a concave surface is formed between the third curved plate 300 and the second curved plate 200, and then the fourth push rod 215 pushes the clamping block 201 to release the third curved plate 300 and the second curved plate 200, and then drives the second moving block 213 through the second guide rail 212 to drive the clamping block 201 to move left back to its original position, and then the third curved plate 300 and the second curved plate 200 are hot stamped. After the hot stamping is completed, the third curved plate 300 and the second curved plate 200 are clamped by the clamping block 201 and driven to move to the right, so that they are placed in the support table 7 and the workers can take them away.

[0057] The protruding portion of the clamping block 201 has beveled edges on both sides, so that when the clamping block 201 is pushed into the arc-shaped plate, the two arc-shaped plates that are closer to each other due to the movement are pushed apart, thereby preventing the clamping block 201 from getting stuck.

[0058] The specific working steps are:

[0059] When the second curved plate 200 and the third curved plate 300 move to the bottom of the right limit block 113, the first push rod 112 on the right pushes the limit block 113 and related parts connected thereto to descend, clamping the second curved plate 200 and the third curved plate 300. When the right limit block 113 descends, the related parts connected thereto will be driven to descend together, and then the fourth guide rail 305 drives the fourth moving block 306 to drive the third clamping plate 307 to descend, pressing the anodized aluminum onto the baffle 303, and then cutting it through the cutter 309 to make the cut The cut electroplated aluminum has the same width as the convex surface formed by the second curved plate 200 and the third curved plate 300; and in the process of the third clamping plate 307 descending, the third clamping plate 307 will first squeeze the front and rear sides of the electroplated aluminum and make it move downward, and when the electroplated aluminum is pushed down, the middle of the electroplated aluminum will contact the arched area in the middle of the baffle 303, so that the baffle 303 blocks the middle of the electroplated aluminum when it descends, preventing the middle of the electroplated aluminum from descending, so that the electroplated aluminum becomes an arc shape that fits the upper part of the baffle 303 after it descends; and in the process of the electroplated aluminum descending, If the two baffles 303 are far apart, the anodized aluminum will be concave and deformed toward the opposite sides of the two baffles 303. Therefore, the initial distance between the two baffles 303 is relatively close. Therefore, when the third clamping plate 307 pushes the anodized aluminum to move downward, the two third guide rails 301 each drive the third moving blocks 302 on the left and right to move backward, thereby driving the two baffles 303 to move backward through the third moving blocks 302, so that the opposite sides of the two baffles 303 are aligned with the two sides of the concave surface, and when the baffles 303 move, they can push the middle part of the anodized aluminum to move to both sides, thereby The compactness of the middle part of the anodized aluminum is increased, thereby preventing the middle part of the anodized aluminum from being dented. When the baffle 303 moves to both sides, the third clamping plate 307 drives the cutter 309 connected to the third fixed plate 308 to descend and contact the upper surface of the baffle 303. When the cutter 309 contacts the baffle 303, the two sides of the anodized aluminum are cut off, and the cut anodized aluminum falls into the collecting tank 303a, preventing the cut anodized aluminum from falling freely into the hot stamped convex surface after separation, thereby affecting the hot stamped pattern. At the same time, it is convenient for subsequent workers to clean.

[0060] While the electroplated aluminum is being pushed and cut, the sixth push rod 319 pushes the fifth fixed block 3110 to rise, thereby driving the second connecting plate 131 and the scraper 132 connected thereto to rise through the fifth fixed block 3110, so that the scraper 132 rises above the upper surface of the concave surface, and then controls the rotating platform 317 to drive the fourth fixed block 318, the sixth push rod 319 and the fifth fixed block 3110 to rotate counterclockwise at a top-down angle, thereby driving the second connecting plate 131 and the scraper 132 connected thereto to rotate through the fifth fixed block 3110, so that the two second connecting plates 131 and the scraper 132 rotate from longitudinal to transverse, and then pushes The second connecting plate 131 and the scraper 132 are lowered, so that the scraper 132 contacts the upper surface of the concave surface; then the fifth push rod 314 pushes the first connecting plate 129 and the push plate 1210 connected thereto to lower down, so that the push plate 1210 pushes the cut electroplated aluminum to lower down, so that it fits the concave surface, and then the two sixth guide rails 315 each drive the sixth moving block 316 connected thereto to drive the rotating platform 317 to move in reverse, so that the rotating platform 317 drives the fourth fixed block 318, the sixth push rod 319, the fifth fixed block 3110 and the second connecting plate 131 and the scraper 132 to move, and while the second connecting plate 131 and the scraper 132 move , the sixth push rod 319 will push the second connecting plate 131 and the scraper 132 to move downward, so that the scraper 132 is always in contact with the concave surface, thereby scraping away the dust particles on the concave surface. At the same time, the fifth guide rail 311 drives the fifth moving block 312 to drive the fixing frame 313 to move backward, so that the fixing frame 313 drives the fifth push rod 314 and the first connecting plate 129 and the push plate 1210 to move, so that the first connecting plate 129 and the push plate 1210 push the cut electroplated aluminum to make it fit the concave surface. After the movement, the first connecting plate 129, the push plate 1210, the second connecting plate 131 and the scraper 132 and other parts will move to the movable groove 113a, so that the right The stamping mechanism 3 descends to perform hot stamping operations on the second curved plate 200 and the third curved plate 300. When the stamping mechanism 3 on the right has finished hot stamping in its original position, all parts will return to their original positions, and then the clamping block 201 will push the hot stamped second curved plate 200 and the third curved plate 300 into the support table 7. It should be noted that the concave hot stamping operation of the second curved plate 200 and the third curved plate 300 is carried out simultaneously with the convex hot stamping operation of the newly placed curved plate. After the second curved plate 200 and the third curved plate 300 are pushed into the support table 7, the new curved plate can be placed and hot stamped again, thereby realizing the automated hot stamping operation of the curved plate.

Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
