Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, and in particular to a hot and cold pressing coating device. Background Technology

[0002] In automobile manufacturing, it is necessary to coat plastic parts with skins, such as using adhesives to bond artificial leather, plastic skin, or genuine leather to the surface of plastic parts to optimize the car's interior. During the coating process, the skin-covered part is placed in a hot press mold to heat the adhesive, improving its adhesion efficiency, and then transferred to a cold press mold for shaping. Because heat inevitably dissipates during the transfer from the hot press mold to the cold press mold, the adhesive activity decreases, affecting the bonding quality and strength between the skin and the plastic part. Furthermore, manual or robotic transfer processes can easily cause skin displacement, wrinkles, or even damage, reducing product yield. Therefore, there is a need for an integrated hot and cold press coating equipment that can quickly complete the part transfer process to reduce heat loss during component transfer and improve the skin coating effect. Summary of the Invention

[0003] The purpose of this invention is to provide a hot and cold pressing coating device, which aims to reduce heat loss during the transfer of parts from a hot pressing mold to a cold pressing mold in order to improve the coating effect of the skin.

Subsequently, the fourth front-push cylinder drives the fourth edge block to move in the opposite direction again, so that the skin snapped onto the inner surface of the transition section is completely pressed onto the inner surface of the transition section.

[0021] In step S18, the third retraction cylinder drives the third edge-sealing block to move closer to the cold-pressing upper mold, folding the skin up to the inner surface of the side of the recessed short section. Then, the third lifting cylinder drives the third edge-sealing block to lift, pressing the folded skin tightly against the side of the recessed short section, completing the edge-sealing operation of the recessed section.

[0022] Furthermore, the short smooth edge-wrapping assembly includes a fifth front insertion cylinder, a fifth front push cylinder, a fifth edge-wrapping cylinder, a fifth front insertion block, and a fifth edge-wrapping block.

[0026] Step S23: The fifth edge-sealing cylinder drives the fifth edge-sealing block to lift, so that the hooked skin adheres to the inner surface of the short smooth section;

[0027] Step S24: The fifth forward-push cylinder drives the fifth edge-sealing block to move away from the cold-pressing upper mold, so that the skin close to the inner surface of the short smooth section is completely pressed against the short smooth section, completing the edge-sealing work of the short smooth section.

[0028] Furthermore, the bending edge-sealing assembly includes a sixth edge-sealing section, a seventh edge-sealing section, and a seventh front insertion section. The sixth edge-sealing section and the seventh edge-sealing section have similar structures, each including a sixth front-push cylinder, a sixth lifting cylinder, a sixth front insertion block, and a sixth edge-sealing block.

[0031] Step S32: The sixth front push cylinder in the sixth edge section and the seventh edge section simultaneously pushes the sixth front insert block towards the cold pressing upper mold, so that the skin folded up by the seventh front insert block is pressed against the inner surface of the bent section.

[0032] Step S33: The sixth lifting cylinder in the sixth and seventh edging sections synchronously drives the sixth edging block to press the skin pressing against the inner surface of the bending section onto the inner surface of the bending section, thus completing the edging operation of the bending section.

[0033] The hot and cold pressing coating equipment provided by this invention, compared with the prior art, involves placing the component in the lower supporting mold, then lowering the upper hot pressing mold to heat the component and skin on the lower supporting mold, improving the adhesion of the adhesive. After a certain period of heat preservation, the upper hot pressing mold is raised, and then the transverse drive quickly moves the worktable to below the upper cold pressing mold, which is then lowered to cool and shape the component on the lower supporting mold. Simultaneously, the coating mechanism is activated to complete the coating operation of the skin on the edge area of ​​the component. This allows for rapid component transfer, reducing heat loss during the transfer process and improving the coating effect. Attached Figure Description

[0075] The present invention will be described in detail below with reference to specific embodiments.

[0076] In this invention, unless otherwise explicitly specified and limited, terms such as "set in," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Directional terms appearing in this invention are used to better describe the characteristics of the features and the relationships between them. It should be understood that when the orientation of this invention changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute spatial limitation on the characteristics of the features and the relationships between them, but only a relative limitation.

[0077] like Figures 1 to 23 As shown, the present invention provides a hot and cold pressing coating device, including an upper support 2 and a lower support 1. The upper support 2 and the lower support 1 are vertically opposite each other and can move closer and further apart. Generally, the upper support 2 and the lower support 1 are driven to move relative to each other by an external mold frame. A positioning support column 3 is provided between the upper support 1 and the lower support 2. The positioning support column 3 is used to position the upper support 1 and the lower support 2 relative to each other. An extrusion upper mold is provided on the upper support 2. A lower mold driving assembly 4 and a supporting lower mold 5 are provided on the lower support 1. The supporting lower mold 5 is engaged with the extrusion upper mold. The supporting lower mold 5 is used to support the inner surface 06 of the component 01. The extrusion upper mold is used to support the upper surface of the component 01 and to shape it.

[0078] The extrusion die includes a hot pressing die 7 and a cold pressing die 8. The lower die drive assembly 4 is used to drive the supporting lower die 5 to slide below the cold pressing die 8 and the hot pressing die 7. When the supporting lower die 5 slides to the first end, the supporting lower die 5 is directly below the hot pressing die 7. When the supporting lower die 5 slides to the second end, the supporting lower die 5 is directly below the cold pressing die 8.

[0079] A hot air assembly 6 is provided on the workbench 42. The hot air assembly 6 is evenly distributed on the outside of the supporting lower mold 5. The hot air assembly 6 is used to heat the skin of the edge of the part 01.

[0080] The upper support 2 is also provided with a covering mechanism 9, which is evenly arranged on the outside of the cold pressing upper mold 8. The covering mechanism 9 is used to cover the component 01 in the cold pressing upper mold 8.

[0081] In this embodiment, the lower mold drive assembly 4 includes a worktable 42, a transverse drive component 40, a transverse guide rail 41, and a proximity switch 43. The transverse guide rail 41 and the transverse drive component 40 are both fixedly installed on the lower bracket 1. The transverse drive component 40 is used to drive the worktable 42 to slide on the transverse guide rail 41. A proximity switch 43 is provided at the front end and the rear end of the transverse guide rail 41, respectively. When the worktable 42 abuts against the proximity switch 43 at the front end of the transverse guide rail 41, the lower mold 5 is located directly below the hot pressing upper mold 7. When the worktable 42 abuts against the proximity switch 43 at the rear end of the transverse guide rail 41, the lower mold 5 is located directly below the cold pressing upper mold 8.

The hot air duct is evenly coiled around the edge of the lower support mold 5, and multiple sets of air outlets are evenly arranged on the hot air duct. When it is necessary to heat the skin area of ​​the workpiece edge, the hot air lifting cylinder will drive the hot air duct and the hot air blower to rise via the hot air bracket, so that the air outlet is close to the edge of the component 01. At the same time, the lower support mold 5 is driven by the transverse drive 40 to come down directly below the hot pressing upper mold 7 for hot pressing. After the hot pressing is completed, the lower support mold 5 is driven by the transverse drive 40 to come down below the cold pressing upper mold 8 for cold pressing and edge wrapping. When it is necessary to perform edge wrapping on the workpiece, the hot air drive will drive the hot air duct and the hot air blower to fall down again to avoid interference between the hot air duct and the covering mechanism 9. Since the hot air component 6 is existing technology and not an improvement of this embodiment, it is not described in detail in this embodiment.

[0083] In this embodiment, the edge of component 01 includes a long smooth segment 02, a bent segment 03, a short smooth segment 04 and an indented segment 05.

[0087] In this embodiment, the recessed edge-wrapping assembly 90 further includes a transition edge-wrapping portion 93. The transition edge-wrapping portion 93 is used to cover the transition section 053 between the recessed long section 052 and the recessed short section 051. The transition edge-wrapping portion 93 includes a fourth front insertion cylinder 9300, a fourth front push cylinder 9301, a fourth edge-wrapping cylinder 9302, a fourth front insertion block 9303, and a fourth edge-wrapping block 9304. The fourth front insertion cylinder 9300 is used to drive the fourth front insertion block 9303 and the fourth front push cylinder 9301 to approach or move away from the cold pressing upper mold 8. The fourth front push cylinder 9301 is used to drive the fourth edge-wrapping cylinder 9302 to approach or move away from the cold pressing upper mold 8. The fourth edge-wrapping cylinder 9302 is used to drive the fourth edge-wrapping block 9304 to fasten the skin to the edge of the inner surface 06 of the component 01.

[0088] In this embodiment, as Figures 16 to 19 As shown, the edge-binding process of the recessed edge-binding component 90 includes the following steps:

[0089] Step S11: The first front insertion cylinder 9100 drives the first front insertion block 9101 to tilt and move downward, so that the front end of the first front insertion block 9101 extends into the side of the recessed long section 052, and folds the skin on the side of the recessed long section 052 toward the inner surface 06 of the component 01.

[0090] In step S12, the second front insertion cylinder 9106 is activated, causing the second front insertion block 9108 to move towards the cold pressing upper mold 8, folding up the skin in the middle area of ​​the recessed long section 052; at the same time, the fourth front insertion cylinder 9300 operates synchronously, causing the fourth front insertion block 9303 to fold up the skin of the transition section 053.

[0091] In step S13, the third front push cylinder 9203 pushes the third front push block 9204 toward the cold pressing upper mold 8, pressing the skin of the middle area of ​​the recessed short section 051 onto the inner surface 06 of the component 01.

[0092] In step S14, the first lifting cylinder 9102 drives the first forward pushing cylinder 9103 and the first edge-binding cylinder 9104 to push downward. Then, the first forward pushing cylinder 9103 pushes the first edge-binding cylinder 9104 and the first edge-binding block 9105 towards the cold pressing upper mold 8, so that the first edge-binding block 9105 hooks the folded skin.

[0093] In step S15, the first edge-binding cylinder 9104 drives the first edge-binding block 9105 to lift, so that the hooked skin is pressed to the inner surface 06 of the component 01. At the same time, the second front-pushing cylinder 9107 is activated, moving the second front-pushing block 9109 towards the cold-pressing upper mold 8, so that the folded skin is pressed against the middle area of ​​the recessed long section 052.

[0094] Step S16: The first forward thrust cylinder 9103 drives the first edge-binding block 9105 to retract, pressing the skin hooked by the first edge-binding block 9105 onto the inner surface 06 of the side of the recessed long section 052 of the component 01.

[0095] In step S17, the fourth forward-pushing cylinder 9301 drives the fourth edge-binding block 9304 to move towards the cold-pressing upper mold 8, bending the skin of the transition section 053 between the recessed long section 052 and the recessed short section 051. Then, the fourth edge-binding cylinder 9302 drives the fourth edge-binding block 9304 to snap the folded skin onto the inner surface 06 of the transition section 053. Subsequently, the fourth forward-pushing cylinder 9301 drives the fourth edge-binding block 9304 to move in the opposite direction, so that the skin snapped onto the inner surface 06 of the transition section 053 is completely pressed onto the inner surface 06 of the transition section 053.

[0096] In step S18, the third retraction cylinder 9201 drives the third edge-binding block 9202 to move towards the cold pressing upper mold 8, folding the skin up to the inner surface 06 of the side of the recessed short section 051. Then, the third lifting cylinder 9200 drives the third edge-binding block 9202 to lift, pressing the folded skin tightly against the side of the recessed short section 051, completing the edge-binding operation of the recessed section 05.

[0097] In this embodiment, as Figure 20 As shown, the short smooth edge-wrapping assembly 94 includes a fifth front insertion cylinder 9400, a fifth front push cylinder 9401, a fifth edge-wrapping cylinder 9402, a fifth front insertion block 9403, and a fifth edge-wrapping block 9404. The fifth front insertion cylinder 9400 is fixedly installed at the bottom of the upper bracket 2. The fifth front insertion cylinder 9400 is used to drive the fifth front insertion block 9403 and the fifth front push cylinder 9401 to tilt closer to or away from the cold pressing upper mold 8. The fifth front push cylinder 9401 is used to drive the fifth edge-wrapping cylinder 9402 to approach or move away from the cold pressing upper mold 8. The fifth edge-wrapping cylinder 9402 is used to drive the fifth edge-wrapping block 9404 to cover the skin of the short smooth segment 04 onto the inner surface 06 of the component 01.

[0098] In this embodiment, as Figure 21 As shown, the edge-binding process of the short smooth edge-binding component 94 includes the following steps:

[0099] Step S21: The fifth front insertion cylinder 9400 moves the fifth front insertion block 9403 toward the cold pressing upper mold 8, and the fifth front insertion block 9403 will fold up the skin of the short smooth section 04.

[0100] Step S22: The fifth forward cylinder 9401 drives the fifth edge block 9404 to move towards the cold pressing upper mold 8, so that the fifth edge block 9404 hooks the skin of the short smooth section 04 that is folded up.

[0101] Step S23: The fifth edge-binding cylinder 9402 drives the fifth edge-binding block 9404 to lift, so that the hooked skin is attached to the inner surface 06 of the short smooth section 04.

[0102] Step S24: The fifth forward cylinder 9401 drives the fifth edge-binding block 9404 to move away from the cold-pressing upper mold 8, so that the skin close to the inner surface 06 of the short smooth section 04 is completely pressed against the short smooth section 04, thus completing the edge-binding work of the short smooth section 04.

[0103] Furthermore, such as Figure 22As shown, the bending and binding assembly 95 includes a sixth binding part 950, a seventh binding part 951, and a seventh front insertion part 952. The sixth binding part 950 and the seventh binding part 951 have similar structures, each including a sixth front push cylinder 9500, a sixth lifting cylinder 9501, a sixth front insertion block 9502, and a sixth binding block 9503. The sixth front push cylinder 9500 is fixedly installed at the bottom of the upper bracket 2. The sixth front push cylinder 9500 is used to drive the sixth lifting cylinder 9501 and the sixth front insertion block 9502 to move closer to or away from the cold pressing upper mold 8. The seventh front insertion part 952 is located near the seventh binding part 951. The seventh front insertion part 952 includes a seventh front insertion cylinder 9520 and a seventh front insertion block 9521. The seventh front insertion cylinder 9520 is fixedly installed at the bottom of the upper bracket 2. The seventh front insertion cylinder 9521 is used to drive the seventh front insertion block 9521 to fold up the skin of the bending section 03.

[0104] In this embodiment, as Figure 23 As shown, the edge-binding process of the bending edge-binding component 95 includes the following steps:

[0105] Step S31: The seventh front insertion cylinder 9520 drives the seventh front insertion block 9521 to move towards the cold pressing upper mold 8, folding up the skin of the bending section 03;

[0106] Step S32: The sixth front push cylinder 9500 in the sixth edge-sealing part 950 and the seventh edge-sealing part 951 simultaneously pushes the sixth front insert block 9502 towards the cold pressing upper mold 8, so that the sixth front insert block 9502 is pressed by the skin folded up by the seventh front insert block 9521 towards the inner surface 06 of the bent section 03.

[0107] Step S33: The sixth lifting cylinder 9501 in the sixth edge-wrapping part 950 and the seventh edge-wrapping part 951 synchronously drives the sixth edge-wrapping block 9503 to press the skin pressing against the inner surface 06 of the bending section 03 onto the inner surface 06 of the bending section 03, thus completing the edge-wrapping operation of the bending section 03.

[0108] In this embodiment, as Figure 11 and Figure 12 As shown, the long smooth edge-binding assembly 96 includes an eighth front insertion cylinder 960 and an eighth front insertion block 961. The eighth front insertion cylinder 960 is used to drive the eighth front insertion block 961 to move towards the cold pressing upper mold 8. Since the structures of different parts of component 01 are different, the long smooth segment 02 has a relatively simple design angle and structure and a long span. Only a single driving component is needed to complete the required edge-binding work in a single drive. Since the long smooth edge-binding assembly 96 is prior art and not an improvement point of this embodiment, it is not described in detail in this embodiment.

[0109] It should be noted that some components may interfere with each other during operation and must be operated in the correct order. However, some components will not interfere with each other during operation. To save processing time, different drive components will operate synchronously without interference. After the entire coating process is completed, the cylinders will reverse the steps of the coating process to retract sequentially, allowing the coated part 01 to be properly removed from the cold-pressing upper mold 8.

[0110] The hot and cold pressing coating equipment provided by this invention, compared with the prior art, after the component 01 is placed in the supporting lower mold 5, the proximity switch 43 detects that the worktable 42 is below the hot pressing upper mold 7. The external mold closing drive mechanism drives the hot pressing upper mold 7 to descend, so as to heat the component 01 on the supporting lower mold 5 and the skin, thereby improving the adhesion effect of the adhesive. After a certain period of heat preservation, the external mold closing drive mechanism lifts the hot pressing upper mold 7. Then, the transverse drive component 40 quickly transfers the worktable 42 to the lower mold 8. The external mold closing drive mechanism drives the lower mold 8 to descend again, so as to cool and shape the component 01 on the supporting lower mold 5. At the same time, the coating mechanism 9 is started to complete the coating operation of the skin on the edge area of ​​the component 01.

[0111] Where there is no conflict, the above embodiments and features can be combined with each other.

[0112] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
