Description

Technical Field

[0001] The utility model relates to the technical field of rubber-coated molds, in particular to a metal sheet rubber-coated mold. Background Art

[0002] The more common method for gluing metal sheets is manual gluing, that is, after the metal sheet is glued to the adhesive tape, the edge of the adhesive tape is manually bent upward 90° along the edge of the metal sheet and then bent inward 90°, and finally the adhesive tape and the metal sheet are pressed together.

[0003] In order to improve the efficiency of metal sheet encapsulation, encapsulation molds are gradually being used to automatically encapsulate metal sheets.

[0004] Specifically, the overmolding mold bends the adhesive sticker upward 90° along the edge of the metal sheet through the upper push block, and then pushes the edge of the adhesive sticker bent upward 90° inward 90° through the inner push block, and finally presses the adhesive sticker located outside the inner push block from above the metal sheet through the pressing block.

[0005] However, for products with a smaller edge width on the adhesive tape, that is, products where the edge of the adhesive tape does not protrude outside the inner push block after the inner push block pushes the edge of the adhesive tape inward and bends it 90°, the existing adhesive encapsulation mold is difficult to apply. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a metal sheet adhesive coating mold, which can be suitable for products with a small edge width on the adhesive label.

[0007] A metal sheet overmolding mold according to the first aspect of the utility model includes: a support block that can move up and down and is used to support a product; a first pressing block located above the support block and used to press the product downward; a first bending block located on one side of the support block, and when the product on the support block drops, the first bending block bends the edge of the product's adhesive label upward; a first translation seat that can horizontally approach and move away from the support block; a second bending block that is movably connected to the first translation seat, and the first translation seat approaches the support block to drive the second bending block to bend the edge of the product's adhesive label inward; a first spring located between the second bending block and the first translation seat, and is used to drive the side of the second bending block close to the support block to tilt upward; a first ejector pin located above the second bending block, and is used to press the second bending block downward to make the side of the second bending block close to the support block drop to press the product's adhesive label.

[0008] A metal sheet overmolding mold according to an embodiment of the utility model has at least the following beneficial effects:

[0009] 1. The utility model provides a support block, a first pressing block and a first bending block. When the first pressing block is pressed down, it cooperates with the support block to clamp the product between the first pressing block and the support block. Then the first pressing block continues to press down to drive the product and the support block to descend. During the descent of the product and the support block, the edge of the adhesive label of the product touches the first bending block, so that the first bending block bends the edge of the adhesive label of the product upward, thereby achieving the effect of the mold automatically bending the edge of the adhesive label of the product upward along the edge of the metal sheet, thereby improving efficiency.

[0010] 2. The utility model sets a first translation seat and a second bending block. When the first bending block bends the edge of the adhesive label of the product upward, the first translation seat drives the second bending block to translate close to the support block, so that the first bending block pushes the edge of the adhesive label after being bent upward inward to bend the edge of the adhesive label inward, thereby achieving the effect of the mold automatically bending the edge of the adhesive label of the product after being bent upward inward, thereby improving efficiency.

[0011] 3. The utility model makes the second bending block movably connected with the first translation seat, and sets the first spring so that the first spring drives the side of the second bending block close to the support block to tilt upward. It can be understood that when the second bending block is close to the support block, the side of the second bending block close to the support block tilts upward, increasing the space between the bottom of the side of the second bending block close to the support block and the top of the support block, so that when the second bending block pushes the adhesive sticker to bend inward, the adhesive sticker has a larger movable space between the bottom of the side of the second bending block close to the support block and the top of the support block, thereby reducing the risk of the adhesive sticker being cut off when the second bending block pushes the edge of the adhesive sticker inward.

[0012] 4. The utility model enables the second bending block to be movably connected with the first translation seat, and a first ejector is arranged above the second bending block, the first ejector is used to press the second bending block downward so that the second bending block descends close to the side of the support block to press the adhesive label of the product. It can be understood that the first ejector presses the second bending block downward so that the second bending block moves downward and cooperates with the support block to press the adhesive label and the metal sheet tightly together, thereby, there is no need for the mold to press down the adhesive label in the area outside the second bending block to fit the adhesive label and the metal sheet, and further, the mold can be suitable for products with smaller edging width on the adhesive label.

[0013] According to some embodiments of the utility model, a hinge axis and a limit axis are arranged between the second bending block and the first translation seat, the second bending block and the first translation seat are hinged through the hinge axis, and the limit axis is used to limit the swing angle of the second bending block.

[0016] According to some embodiments of the utility model, a first chamfer is provided at the top end of the first bending block on one side close to the supporting block, and the first chamfer is used to guide the adhesive label of the product.

[0018] According to some embodiments of the utility model, it also includes an upper mold mechanism and a first cylinder for driving the upper mold mechanism to rise and fall, the upper mold mechanism includes a stripping plate and a fourth spring for squeezing the stripping plate to move downward, and the first pressing block is arranged at the bottom of the stripping plate.

[0019] According to some embodiments of the utility model, a lower mold mechanism is further included, wherein the lower mold mechanism includes a floating block and a sixth spring supporting the bottom of the floating block, and the floating block is used to support the product between the supporting block and the first pressing block.

[0020] According to some embodiments of the utility model, the stripping plate is further provided with a third push rod, and the upper mold mechanism descends so that the stripping plate drives the third push rod to press the floating block downward.

[0036] A metal sheet overmolding mold according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0037] Reference Figure 1 The product 100 used by the metal sheet overmolding mold of the embodiment of the utility model includes a metal sheet 110 and an adhesive sticker 120. The product 100 is supported by a positioning support belt 130, and multiple products 100 are arranged on the positioning support belt 130 at one time.

[0038] Reference Figure 2 , Figure 3 and Figure 5 A metal sheet encapsulation mold according to an embodiment of the utility model includes a mold frame, a lower mold mechanism, an upper mold mechanism and a first cylinder 230. The lower mold mechanism is fixed on the mold frame, the upper mold mechanism is located above the lower mold mechanism, the first cylinder 230 is located above the upper mold mechanism and is fixedly connected to the mold frame, and the first cylinder 230 is used to drive the upper mold mechanism to rise and fall.

[0039] Reference Figure 3 and Figure 4 In some specific embodiments, the upper mold mechanism includes an upper pad and an upper clamping plate, the first cylinder 230 is connected to the upper pad, and the upper clamping plate is installed at the bottom of the upper pad.

[0040] Furthermore, the lower mold mechanism is provided with a support block 140 , a first bending block 160 , a first translation seat 170 , a second bending block 180 , and a first spring 190 , and the upper mold mechanism is provided with a first pressing block 150 and a first ejector pin 200 .

[0041] The supporting block 140 can move up and down, and is used to support the product 100 .

[0042] As for the first pressing block 150 , the first pressing block 150 is located above the supporting block 140 , and the first pressing block 150 is used to press down the product 100 .

[0043] As for the first bending block 160 , the first bending block 160 is located at one side of the supporting block 140 . When the product 100 on the supporting block 140 descends, the first bending block 160 bends the edge of the adhesive label 120 of the product 100 upward.

[0044] In this embodiment, a support block 140, a first pressing block 150 and a first bending block 160 are provided. When the first pressing block 150 is pressed down, it cooperates with the support block 140 to clamp the product 100 between the first pressing block 150 and the support block 140. Then, the first pressing block 150 continues to press down to drive the product 100 and the support block 140 to descend. During the descent of the product 100 and the support block 140, the edge of the adhesive label 120 of the product 100 touches the first bending block 160, so that the first bending block 160 bends the edge of the adhesive label 120 of the product 100 upward, thereby achieving the effect of the mold automatically bending the edge of the adhesive label 120 of the product 100 upward along the edge of the metal sheet 110, thereby improving efficiency.

[0045] As for the first translation seat 170 , the first translation seat 170 can horizontally approach and move away from the supporting block 140 .

[0046] As for the second bending block 180 , the second bending block 180 is movably connected to the first translation seat 170 , and the first translation seat 170 is close to the support block 140 to drive the second bending block 180 to bend the edge of the adhesive label 120 of the product 100 inward.

[0047] In this embodiment, a first translation seat 170 and a second bending block 180 are provided. When the first bending block 160 bends the edge of the adhesive label 120 of the product 100 upward, the first translation seat 170 drives the second bending block 180 to translate close to the support block 140, so that the first bending block 160 pushes the edge of the adhesive label 120 bent upward inward to bend the edge of the adhesive label 120 inward, thereby achieving the effect of the mold automatically bending the edge of the adhesive label 120 of the product 100 inward after being bent upward, thereby improving efficiency.

[0048] As for the first spring 190 , the first spring 190 is located between the second bending block 180 and the first translation seat 170 , and the first spring 190 is used to drive the side of the second bending block 180 close to the supporting block 140 to tilt upward.

[0049] In this embodiment, the second bending block 180 is movably connected to the first translation seat 170, and the first spring 190 is provided so that the first spring 190 drives the side of the second bending block 180 close to the support block 140 to tilt upward. It can be understood that when the second bending block 180 is close to the support block 140, the side of the second bending block 180 close to the support block 140 tilts upward, increasing the space between the bottom of the side of the second bending block 180 close to the support block 140 and the top of the support block 140. Therefore, when the second bending block 180 pushes the adhesive tape 120 to bend inward, there is a larger movable space between the bottom of the side of the second bending block 180 close to the support block 140 and the top of the support block 140, thereby reducing the risk of breaking the adhesive tape 120 when the second bending block 180 pushes the edge of the adhesive tape 120 inward.

[0050] The first ejector pin 200 is located above the second bending block 180 , and is used to press the second bending block 180 downward so that the second bending block 180 close to the side of the support block 140 descends to press the adhesive label 120 of the product 100 .

[0051] In this embodiment, the second bending block 180 is movably connected to the first translation seat 170, and a first ejector pin 200 is arranged above the second bending block 180. The first ejector pin 200 is used to press the second bending block 180 downward so that the second bending block 180 moves down close to the side of the support block 140 to press the adhesive tape 120 of the product 100. It can be understood that the first ejector pin 200 presses the second bending block 180 downward so that the second bending block 180 moves downward and cooperates with the support block 140 to press the adhesive tape 120 and the metal sheet 110 together. Therefore, there is no need for the mold to press down the adhesive tape 120 located outside the second bending block 180 to fit the adhesive tape 120 and the metal sheet 110. Furthermore, the mold can be suitable for products 100 with a smaller edging width on the adhesive tape 120.

[0052] In some specific embodiments, a hinge shaft 210 and a limit shaft 220 are provided between the second bending block 180 and the first translation seat 170 . The second bending block 180 and the first translation seat 170 are hinged via the hinge shaft 210 , and the limit shaft 220 is used to limit the swing angle of the second bending block 180 .

[0053] It can be understood that the second bending block 180 is hinged to the first translation seat 170 via the hinge shaft 210, so that the second bending block 180 can swing along the hinge shaft 210, thereby making the relative movement of the second bending block 180 and the first translation seat 170 more stable. In addition, by setting a limit shaft 220 between the second bending block 180 and the first translation seat 170, the limit shaft 220 can limit the swing angle of the second bending block 180, thereby preventing the first spring 190 from driving the second bending block 180 to swing up too large an angle and affecting the bending effect of the second bending block 180 on the adhesive 120 of the product 100.

[0054] Specifically, the limit shaft 220 can be fixedly connected to one of the second bending block 180 and the first translation seat 170, and the other of the second bending block 180 and the first translation seat 170 is provided with a limit hole, the aperture of the limit hole is larger than the axis diameter of the limit shaft 220, and the limit hole accommodates the movement of the limit shaft 220 and limits the limit shaft 220.

[0055] In some specific embodiments, the upper mold mechanism includes a lower insert block 240, and the upper end surface of the first translation seat 170 away from the support block 140 is provided with a first bevel 250, and the lower insert block 240 descends to squeeze the first bevel 250 to drive the first translation seat 170 close to the support block 140.

[0056] It can be understood that when the upper mold mechanism descends, the lower insert block 240 descends synchronously. During the descending process of the lower insert block 240, after the lower insert block 240 abuts against the first bevel 250 of the first translation seat 170, the first bevel 250 guides the lower insert block 240 so that the lower insert block 240 pushes the first translation seat 170 to horizontally approach the support block 140. As a result, during the process of the upper mold mechanism descending and closing the mold with the lower mold mechanism, the lower insert block 240 can drive the first translation seat 170 to automatically approach the support block 140 to bend the adhesive label 120 of the product 100 inward, thereby eliminating the need to set up an additional driving device to drive the first translation seat 170 to translate close to the support block 140, thereby reducing the cost of the mold.

[0057] Specifically, the top end of the lower insert block 240 is connected to the upper clamping plate.

[0058] Furthermore, a second bevel is provided at the bottom of the lower insert block 240 , and the second bevel is used to abut and cooperate with the first bevel 250 , thereby making the transmission between the lower insert block 240 and the first translation seat 170 smoother.

[0059] In some specific embodiments, a second spring 260 is arranged between the first translation seat 170 and the support block 140, and the second spring 260 is used to drive the first translation seat 170 away from the support block 140. Therefore, when the lower insert block 240 pushes the first translation seat 170 close to the support block 140, the first translation seat 170 and the support block 140 squeeze and compress the second spring 260. After the lower insert block 240 is separated from the first translation seat 170, the elastic force generated by the second spring 260 can automatically push the first translation seat 170 away from the support block 140, so that the first translation seat 170 is reset.

[0060] In some specific embodiments, a first chamfer 270 is provided at the top of the first bending block 160 on one side close to the support block 140. The first chamfer 270 is used to guide the adhesive tape 120 of the product 100. Thus, when the product 100 descends along with the support block 140, the edge of the adhesive tape 120 of the product 100 first abuts against the first chamfer 270 of the first bending block 160. The first chamfer 270 guides the edge of the adhesive tape 120, so that the edge of the adhesive tape 120 is more easily bent upward by the first bending block 160.

[0061] In some specific embodiments, the upper mold mechanism includes a third spring 280, and the first ejector pin 200 is slidably arranged on the upper mold mechanism up and down. The bottom end of the third spring 280 abuts against the top end of the first ejector pin 200, and the third spring 280 is used to press the first ejector pin 200 downward, so that when the first ejector pin 200 collides with the second bending block 180, the third spring 280 can buffer the first ejector pin 200. At the same time, as the upper mold mechanism descends, after the first ejector pin 200 presses the second bending block 180, the third spring 280 can continue to provide holding pressure to the first ejector pin 200, so that the second bending block 180 can press the adhesive label 120 and the metal sheet 110 tighter.

[0062] In some specific embodiments, the upper mold mechanism includes a stripper plate 290 and a fourth spring 300 that presses the stripper plate 290 to move downward, and the first pressing block 150 is disposed at the bottom of the stripper plate 290 .

[0063] It can be understood that when the upper mold mechanism descends, the stripping plate 290 drives the first pressure block 150 to descend synchronously. When the first pressure block 150 squeezes the support block 140 into place, the support block 140 stops descending and limits the first pressure block 150, so that the first pressure block 150 stops descending. At the same time, the stripping plate 290 also stops descending. At this time, the upper mold mechanism continues to descend and cooperates with the stripping plate 290 to compress the fourth spring 300. When the upper mold mechanism rises, the elastic force of the fourth spring 300 on the stripping plate 290 causes the stripping plate 290 to drive the first pressure block 150 to keep pressing the support block 140, thereby avoiding the second bending block 180 from completely separating from the top of the product 100 and causing the product 100 to collide with the second bending block 180 and damage the product 100.

[0064] In some specific embodiments, the lower mold mechanism includes a floating block 330 and a sixth spring 340 supporting the bottom of the floating block 330. The floating block 330 is used to support the product 100 between the supporting block 140 and the first pressing block 150, so that the product 100 can be moved on the floating block 330 to avoid the supporting block 140 interfering with the movement of the product 100.

[0065] It should be explained that the positioning support belt 130 is slidably disposed on the floating block 330 so that the floating block 330 places the product 100 between the supporting block 140 and the first pressing block 150 .

[0066] In some specific embodiments, the stripping plate 290 is also provided with a third push rod 350, and the upper mold mechanism descends so that the stripping plate 290 drives the third push rod 350 to press the floating block 330 down. Thus, when the upper mold mechanism descends, the third push rod 350 can drive the floating block 330 to descend synchronously, so that the movement of the floating block 330 is synchronized with the movement of the product 100.

[0067] In some specific embodiments, the support block 140 slides up and down on the lower mold mechanism, and the lower mold mechanism includes a second push rod 310 and a fifth spring 320 that presses the second push rod 310 upward. The top end of the second push rod 310 abuts against the bottom end of the support block 140, so that when the first pressure block 150 rises, the fifth spring 320 can push the support block 140 upward and reset it.

[0068] In some specific embodiments, the lower mold mechanism is provided with a pressure-maintaining base, and the upper mold mechanism is correspondingly provided with a pressure-maintaining top seat, and the pressure-maintaining base and the pressure-maintaining top seat cooperate to press and maintain the pressure of the product 100 after encapsulation.

[0069] Reference Figure 6 and Figure 7 The working principle of a metal sheet encapsulation mold in an embodiment of the utility model is as follows:

[0070] The positioning support belt 130 with the product 100 is installed on the floating block 330, and the first cylinder 230 is started. The first cylinder 230 drives the upper mold mechanism to descend. During the descent of the upper mold mechanism, the third push rod 350 abuts against the floating block 330, and the first pressing block 150 abuts against the product 100 on the floating block 330. The floating block 330 and the product 100 descend synchronously. When the product 100 abuts against the supporting block 140, the first pressing block 150 and the supporting block 140 clamp the product 100 and drive the supporting block 140 to descend synchronously. During the descent of the product 100, the edge of the adhesive label 120 of the product 100 contacts the first bending block 160, and the first bending block 160 bends the edge of the adhesive label 120 upwards. When the support block 140 is lowered into place, the support block 140, the product 100, and the first pressing block 150 stop descending.

[0071] Then, the upper pad and the upper clamp of the upper mold mechanism continue to descend, and the upper pad drives the lower insert block 240 to continue to descend, and the second bevel angle of the lower insert block 240 abuts against the first bevel angle 250 of the first translation block to bring the first translation block close to the support block 140, and the first translation block drives the second bending block 180 close to the support block 140 and bends the edge of the upward bent adhesive tape 120 inward. At this time, the first spring 190 squeezes the side of the second bending block 180 close to the support block 140 to tilt upward.

[0072] When the second bending block 180 bends the edge of the adhesive tape 120 into place, as the upper pad continues to descend, the first push rod pushes the second bending block 180 down so that the second bending block 180 swings downward to press the adhesive tape 120 and the metal sheet 110. At the same time, the third spring 280 maintains pressure on the first top plate.

[0073] After the rubber encapsulation is completed, the first cylinder 230 drives the upper mold mechanism to rise. After the first push rod is separated from the second bending block 180, the first spring 190 drives the second bending block 180 to tilt upward and reset. Then the lower insert block 240 is separated from the first translation block, and the second spring 260 drives the first translation block away from the support block 140 to reset. Then, the stripping plate 290 drives the first pressure block 150 to rise. At the same time, the fifth spring 320 drives the support block 140 to rise and reset, and the sixth spring 340 drives the floating block 330 to rise and reset.

[0074] Then, the positioning support belt 130 is moved on the floating block 330 to continue encapsulating the next product 100 .
