Description

Technical Field

[0001] The invention relates to the technical field of blister equipment, in particular to a blister device for a vehicle sealing part. Background Art

[0002] Blistering is a common plastic molding process, which belongs to thermoplastic plastic molding technology. It absorbs heated plastic film onto the mold surface and uses the vacuum to make the plastic fit the mold tightly, thus forming the desired shape. In the production of automotive seals, the heated PE material is usually transported to the blistering equipment, and the PE material is blister-molded to obtain seals of corresponding shapes.

[0003] However, after the blistering is completed, the existing equipment is often unable to directly cut the formed seals. The blistered PE material needs to be sent out and cut and trimmed by external cutting equipment to obtain the required seals. This is relatively troublesome and inconvenient. It not only increases the production process of the seals, affects the production efficiency of the seals, but also increases the equipment cost. In the blistering process of PE materials, different processes such as positioning, blistering, and demolding of the PE materials are separately controlled and driven by multiple stations. This leads to the need to coordinate and debug the devices at different stations before the production line is started to ensure perfect coordination between different processes, which wastes time and slows down the startup efficiency, thereby affecting the production of seals.

When the cutting frame 30 descends, the positioning assembly 40 can position the PE material, and the transmission assembly 50 drives the lower mold body 20 to rise. With the cooperation of the blister mechanism 70, the blister molding of the seal is completed. The braking mechanism 60 limits the movement of the lower mold body 20, so that the lower mold body 20 remains stationary after the seal is formed, and then the cutting of the seal is completed by the cutting frame 30.

[0032] refer to Figure 1 , Figure 2 as well as Figure 5 A frame 11 is fixedly installed on the base 10, and a lower mold body 20 is slidably arranged inside the frame body 11. A top plate 12 is arranged on the top of the frame body 11. A through hole 13 and a through groove 14 are opened inside the top plate 12 to facilitate the lower mold body 20 to pass through the frame body 11. A guide rod 15 is fixedly installed on the outside of the frame body 11. The cutting frame 30 is slidably arranged on the guide rod 15 and can be close to the lower mold body 20. A limiting groove 16 is opened in the frame wall of the frame body 11, and a positioning groove 121 is opened on the top of the top plate 12. The internal thread of the top plate 12 is connected with a first bolt 122, and the end of the first bolt 122 is threadedly connected in the frame wall of the frame body 11 to facilitate the disassembly and replacement of the top plate 12.

[0033] refer to Figure 5 and Figure 6The lower mold body 20 includes a base 21, a support plate 22 and a template 23. The base 21 is located below the frame 11, and the top end of the base 21 is slidably assembled inside the frame 11. The support plate 22 is fixedly installed inside the base 21. The template 23 is arranged on the support plate 22. The template 23 is located directly below the through slot 14, and its shape and size are adapted to the through slot 14. When the base 21 is raised, it can pass through the through slot 14, and then push the PE material to deform for blistering. A limiting plate 211 is fixedly installed on the top of the base 21, and the top end of the limiting plate 211 is slidably assembled inside the limiting slot 16. The internal thread of the support plate 22 is connected with a second bolt 221, and the end of the second bolt 221 is threadedly connected in the template 23, so as to facilitate the disassembly and replacement of the template 23 and the processing of seals of different shapes.

[0034] refer to Figure 2 , Figure 3 as well as Figure 5 The cutting frame 30 includes a cross plate 31 and a cutter 32. The cross plate 31 is arranged just above the frame 11. A side plate 311 is fixedly connected to the side wall of the cross plate 31, and the side plate 311 is slidably assembled on the guide rod 15. A hydraulic cylinder (not shown) is arranged on the top of the cross plate 31 to drive the cross plate 31 to rise and fall, so that the side plate 311 slides on the guide rod 15. The cutter 32 is arranged at the bottom of the cross plate 31, and the cutter 32 is located just above the through groove 14 and is adapted to the shape and size of the template 23, so that when the cross plate 31 is lowered, the seal completed by the blister can be cut by the cutter 32. A knife seat 321 is fixedly installed on the cutter 32, and a third bolt 322 is threadedly connected to the knife seat 321, and the end of the third bolt 322 is threadedly connected in the cross plate 31, so as to facilitate the disassembly and assembly of the knife seat 321 on the cross plate 31, and different cutters 32 can be replaced according to the shape of the template 23.

[0035] refer to Figure 1-Figure 5The positioning assembly 40 includes a positioning frame 41 and a spring 42. The positioning frame 41 is arranged directly below the transverse plate 31. The spring 42 is arranged between the positioning frame 41 and the transverse plate 31, so that the transverse plate 31 can be lowered with the positioning frame 41 through the spring 42. After the positioning frame 41 falls on the PE material, the spring 42 is compressed, and then the positioning frame 41 presses the PE material. A slider 411 is fixedly connected to the side wall of the positioning frame 41, and the slider 411 is slidably assembled on the guide rod 15. The spring 42 is sleeved on the outside of the guide rod 15, and the spring 42 The two ends are respectively fixed on the slider 411 and the side plate 311. When the cross plate 31 descends, the side plate 311 can cooperate with the slider 411 to squeeze the spring 42. The bottom of the positioning frame 41 is fixedly connected with a positioning protrusion 412 adapted to the positioning groove 121, and the positioning protrusion 412 can enter the positioning groove 121 when the positioning frame 41 descends. After the positioning frame 41 falls above the PE material, the positioning protrusion 412 can press the PE material into the inside of the positioning groove 121, thereby improving the positioning effect of the PE material.

[0036] refer to Figure 3 and Figure 4 The transmission assembly 50 includes a driving rack 51, a transmission gear 52 and a transmission rack 53. The driving rack 51 is fixedly installed at the bottom of the horizontal plate 31. The transmission gear 52 is rotatably assembled on the side wall of the frame 11 and can be meshed with the driving rack 51 when it descends. The transmission rack 53 is fixedly installed on the base 21 and is arranged opposite to the driving rack 51. The transmission rack 53 is meshed with the transmission gear 52, so that when the horizontal plate 31 descends, the driving rack 51 is meshed with the transmission gear 52 and then drives the transmission gear 52 to rotate. The transmission gear 52 drives the driving rack 53 to move upward during rotation, so that the driving rack 53 drives the base 21 to lift for the blister processing of the seal.

[0037] refer to Figure 3 and Figure 4 The brake mechanism 60 includes a brake block 61 and a brake rod 62. The brake block 61 is fixedly mounted on the transmission gear 52. A slot 63 is provided inside the brake block 61. The brake rod 62 is fixedly mounted on the bottom of the cross plate 31. The brake rod 62 is located directly above the brake block 61 and is matched with the slot 63. When the driving rack 51 is disengaged from the transmission gear 52 during the descending process, the slot 63 just stays directly below the brake rod 62, so that the brake rod 62 can be inserted into the slot 63 to limit the rotation of the transmission gear 52, thereby keeping the position of the base 21 stationary, and the cross plate 31 can continue to descend to cut the seal by the cutter 32.

[0038] refer to Figure 2The blister mechanism 70 includes a vacuum pump 71 and a blister tube 72. The vacuum pump 71 is fixedly mounted on the base 10. The blister tube 72 is arranged on the vacuum pump 71. One end of the blister tube 72 away from the vacuum pump 71 is connected to the interior of the base 21, so that the vacuum pump 71 can evacuate the base 21 through the blister tube 72, extract the air in the base 21, and make the PE material stick to the surface of the template 23.

[0039] Working principle: After the PE material is heated, it is transported to the top of the support plate 22. The hydraulic cylinder drives the horizontal plate 31 to descend, so that the positioning frame 41 falls to the surface of the PE material. The horizontal plate 31 continues to descend to make the driving rack 51 move closer to the transmission gear 52. During this process, the spring 42 is gradually compressed, so that the positioning frame 41 presses the PE material from above;

[0040] The driving rack 51 pushes the transmission gear 52 to rotate during the descent, so that the transmission gear 52 pushes the transmission rack 53 to move upward, so that the base 21 rises in the frame 11, and the template 23 on the support plate 22 passes through the through groove 14 and pushes the PE material from below to deform. When the driving rack 51 separates from the transmission gear 52 during the descent, the slot 63 just stays under the brake rod 62, so that the brake rod 62 can be inserted into the slot 63 on the brake block 61, limiting the rotation of the transmission gear 52, so that the base 21 and the template 23 remain in place, and then the vacuum pump 71 evacuates the base 21 to extract the air in the base 21, and adsorbs the PE material to the surface of the template 23, and then obtains a seal of a desired shape;

[0041] The cross plate 31 continues to descend, the brake rod 62 slides in the slot 63 to keep the base 21 stationary, and the cutter 32 cuts the blister-formed seal from above to separate the seal from the PE material. Then the cross plate 31 is adjusted to lift, the brake rod 62 rises and disengages from the slot 63, and the drive rack 51 engages with the transmission gear 52 again, pushing it to rotate in the opposite direction, so that the transmission rack 53 descends with the base 21, and the template 23 is received in the frame 11. The seal is blocked by the top plate 12 and is demolded and separated from the template 23, and stays above the top plate 12. The positioning frame 41 is lifted to release the positioning of the PE material, and then the PE material is conveyed forward to push the seal away from the top plate 12, and the cross plate 31 is lowered again to carry out the blistering operation of the next group of seals.

[0042] In the present invention, the positioning, blistering and cutting of the PE material are completed by the unified control of the descent of the horizontal plate 31, which is simple and quick to operate, and there is no need to perform coordination and debugging between different functional components, which effectively reduces the difficulty of using the equipment, and enables the positioning, blistering and cutting of the PE material to be integrated, without the need for separate cutting of the seals at a later stage, eliminating the cutting process in the production of seals, saving equipment costs, optimizing the production process of seals, and improving the production efficiency of seals.

[0043] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
