Description

Technical Field

[0001] This application relates to the field of mold technology, and more specifically to a male mold for automobile side panels. Background Technology

[0002] The center armrest, also known as the center console, is an interior component located between the front seats of a car. Its primary function is to provide arm support for the driver, alleviating fatigue and stiffness during long drives. The center armrest includes side panels, which are often covered with a leather-like finish for aesthetic purposes. Vacuum forming is mainly divided into several forms: male mold forming, female mold forming, and moldless forming.

[0003] Patent document (CN103817915B) discloses a vacuum forming method using a male mold, which generally includes the following steps: 1. Heating and softening a PVC sheet; 2. Moving the softened PVC sheet between an upper mold and a lower mold, pressing the upper mold down close to the PVC sheet to a distance of about 3mm, then raising the lower mold until its bottom is completely pressed against the upper mold, activating the vacuum equipment, and initiating a vacuum in the lower mold, thereby stretching and deforming the PVC sheet, which then adheres to the mold contour surface to form the desired shape, and then turning off the vacuum equipment; 3. After the PVC sheet has stretched and formed the desired shape, raising the upper mold to begin cooling and setting; 4. Removing the formed PVC sheet from the mold. Currently, when covering the side panel with the outer skin, the outer skin is softened by heating and then vacuumed to cover it. However, since the overall surface area of ​​the outer skin (the plastic PVC sheet mentioned above) is larger than the surface area of ​​the lower mold contour, after the outer skin is attached to the side panel, the processing personnel still need to separately cut off the excess outer skin, resulting in low processing efficiency.

[0004] Therefore, there is a need for a positive mold for automotive side panels that can cover the skin onto the side panel and remove excess skin. Summary of the Invention

[0005] The main objective of this application is to provide a male mold for automotive side panels, used to adhere skin to a plastic side panel. The male mold includes a frame, an upper mold, and a lower mold. The upper mold includes an outer frame and two die-cutting molds.

[0022] Schematic illustration of a male mold for a car side panel, for reference. Figures 1 to 6 According to a preferred embodiment of the present invention, a positive mold for automobile side panels is used to adsorb the skin onto a plastic side panel, comprising an upper mold 10, a lower mold 20, and a frame.

[0023] Specifically, such as Figures 1 to 3 As shown, the upper mold 10 and the lower mold 20 are both vertically mounted on the frame. The upper mold 10 includes an outer frame 101 and two cutting dies 102. The outer frame 101 has a first cavity 1011. The cutting dies 102 are vertically mounted in the first cavity 1011. The two cutting dies 102 are symmetrically arranged and are both arched. In addition, the lower mold 20 includes a lower working mold 201 and a vacuuming component 202. The lower working mold 201 includes a placement mold 2011. The plastic side plate is inserted into the placement mold 2011. The skin is located on the plastic side plate. The placement mold 2011 and the vacuuming component 202 both have air holes communicating with the vacuuming component 202. The placement mold 2011 is designed to mimic the shape of the cutting dies 102. The outer contour of the placement mold 2011 has a cutting groove 20111 for the cutting dies 102 to pass through.

[0024] In addition, the positive mold for the car side panel also includes a feeding frame, a heating element, and a glue spraying device. The feeding frame is used to place the skin. The feeding frame is movably disposed on the frame and is located between the upper mold 10 and the lower mold 20. Furthermore, the upper mold and the placement mold 2011 are heated by the heating element, and glue is sprayed onto the plastic side panel by the glue spraying device.

[0025] It should be noted that in this application, the material of the plastic side panel is ABS plastic, PC plastic, or a mixture of 30% ABS plastic and 70% PC plastic, and the material of the skin is thermoplastic polyolefin. During processing, the plastic side panel is inserted into the placement mold 2011, and water-based adhesive is sprayed onto the plastic side panel. Then, the feeding frame moves between the upper mold 10 and the lower mold 20. Subsequently, the upper mold 10 and the lower mold 20 move towards each other, that is, the upper mold 10 moves downward a predetermined distance, and the lower mold 20 moves upward a predetermined distance, causing the top surface of the plastic side panel to abut against the bottom surface of the placement mold 2011. It should be pointed out that at this time, the die 102 moves upward relative to the outer frame 101, and the lowest point of the outer frame 101 is lower than the lowest point of the die 102. At this time, the outer frame 101 presses against the skin. The four sides of the skin are then vacuumed. The vacuuming component 202 evacuates the air holes, causing the unpressed portion of the skin inside the outer frame 101 to stretch and deform under air pressure, and adhere to the placement mold 2011. This initial pressing action lasts for 3-5 seconds. Then, the upper mold 10 moves upward a predetermined distance, and the cutting mold 102 moves downward a predetermined distance and extends a predetermined distance from the lowest point of the outer frame 101. The upper mold 10 moves downward a predetermined distance again, and the cutting mold 102 contacts and cuts the skin. At this time, the cutting mold 102 extends into the cutting groove 20111, completing the wrapping of the skin onto the side plate and removing excess skin. Then, the upper mold 10, the lower mold 20, and the feeding frame are reset. It is evident that, compared to the prior art, this method has the advantage of wrapping the skin onto the side plate and removing excess skin.

[0026] Furthermore, to facilitate rapid cooling after the skin is applied to the side plate, such as... Figure 4 As shown, the lower working mold 201 also includes a cooling plate 2012, which is located below the placement mold 2011, and a plurality of cooling pipes are inserted inside the cooling plate 2012.

[0027] Furthermore, in this application, as Figure 2 , Figure 3 and Figure 5 As shown, the upper mold 10 also includes an upper main plate 103, a lifting drive device 104, and a lifting plate 105. The lifting drive device 104 is mounted on the upper main plate 103, and the lifting plate 105 is fixedly connected to the push rod of the lifting drive device 104. The outer frame 101 is vertically arranged on the upper main plate 103. The lifting drive device 104 and the lifting plate 105 are both located in the first cavity 1011, and the die 102 is mounted on the lifting plate 105.

[0028] It should be noted that the upper plate 103 is lifted and mounted on the frame; under normal conditions, the die 102 extends a predetermined distance from the outer frame 101; at this time, the push rod of the lifting drive device 104 extends to its maximum length, and the lifting plate 105 moves to its lowest position.

[0029] In addition, in this application, the outer frame 101 includes four vertical plates, all of which are connected to the upper main plate 103 and spliced ​​together to form the outer frame 101 with a rectangular cross section.

[0030] Furthermore, to achieve the fixation of the position of the die 102 under normal conditions, such as Figure 5 As shown, the upper mold 10 also includes a locking structure 106, which is located on the outer frame 101. The locking structure 106 includes a locking block 1061, which is slidably disposed on the outer frame 101. When the push rod of the lifting drive device 104 extends to its maximum length and the locking block 1061 extends into the first recess 1011, the locking block 1061 abuts against the top of the die 102 and restricts the die 102 from moving upward.

[0031] Furthermore, to achieve the sliding of the card block 1061, as follows: Figure 5 As shown, the locking structure 106 further includes a linear drive device 1062, which corresponds one-to-one with the locking block 1061. The linear drive device 1062 is mounted on the outer frame 101, and the push rod of the linear drive device 1062 is fixedly connected to the locking block 1061.

[0032] It should be noted that when the push rod of the linear drive device 1062 is activated, the locking block 1061 extends into the first cavity 1011 or moves away from the die 102.

[0033] In addition, to achieve fine-tuning of the height direction of the fixed position of the die 102, such as Figure 6 As shown, the card block 1061 has a first inclined surface 1063, and the lifting plate 105 has a second inclined surface that cooperates with the first inclined surface 1063.

[0034] Furthermore, to guide the lifting plate 105 during its vertical movement, such as... Figure 2 and Figure 5 As shown, the middle section of the lifting plate 105 has a through hole 1051, and the upper mold 10 also includes a guide member 107. One end of the guide member 107 is disposed on the upper main plate 103, and the other end of the guide member 107 passes through the through hole 1051 and abuts against one side of the die 102.

[0035] Furthermore, in this application, to facilitate the movement of the male mold for the automobile side panel by a forklift, such as... Figure 4 As shown, the lower mold 20 also has a heightening seat 203 and a lower main plate 204. The top and bottom of the heightening seat 203 are connected to the lower working mold 201 and the lower main plate 204, respectively. The heightening seat 203 is arranged at intervals along the length of the lower main plate 204 to form a plurality of insertion cavities 205.

[0036] It should be noted that during handling, the forklift's front fork can be inserted into the insertion cavity 205 to move the male mold for the automobile side panel. Additionally, when the male mold for the automobile side panel is placed in the designated position, the lower main plate 204 is raised and lowered onto the frame.

[0037] Furthermore, to reduce wear, such as Figure 4 As shown, the lower mold 20 also includes a channel steel 206, which is fixedly connected to the side of the lower working mold 201 near the lower main plate 204, and the channel steel 206 has a socket.

[0038] In summary, the positive mold for automobile side panels described in the embodiments of this application is explained, which provides advantages such as being able to cover the skin onto the side panel and remove excess skin.

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
