Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an injection molding and stamping integrated mold for an automobile carbon fiber decorative plate. Background Art

[0002] Today, the main ways to reduce the weight of automobiles are to reduce the weight of materials and structures. Parts made of carbon fiber composite materials are light in weight and high in strength. Therefore, in the existing technology, automobile interior panels have gradually developed into decorative panels made of carbon fiber materials.

[0003] In the prior art, there are usually two ways to manufacture carbon fiber decorative panels. The first is to stamp the entire carbon fiber device panel with carbon fiber materials, including the carbon fiber decorative panel and fasteners. However, this method of using carbon fiber materials as a whole has a high manufacturing cost. The second is to stamp the carbon fiber decorative panel with carbon fiber materials, and then use plastic injection molding fasteners to bond or ultrasonically weld the fasteners to the carbon fiber decorative panel. However, when the inventor used the second production method, he found that the carbon fiber device panel was easily separated from the fasteners when connected by bonding, and it was not reliable to use. When ultrasonic welding was used, welding spots would be formed on the surface of the carbon fiber decorative panel, resulting in poor surface flatness of the carbon fiber decorative panel.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Please also read Figures 1 to 8 The injection molding and stamping integrated mold of the automotive carbon fiber decorative plate 30 provided in the embodiment of the present application is now described. The injection molding and stamping integrated mold of the automotive carbon fiber decorative plate 30 comprises: a lower mold base 10 and an upper mold base 20.

[0036] The top of the lower mold base 10 is movably installed with a lower mold core 11 and a first row position 12, which can be moved left and right. The first row position 12 is located on the left and / or right side of the lower mold core 11; the upper mold base 20 is movably installed on the top of the lower mold base 10, and the upper mold core 21 is installed on the bottom of the upper mold base 20; when the upper mold base 20 and the lower mold base 10 are molded together, the upper mold core 21, the lower mold core 11 and the first row position 12 can stamp and form the carbon fiber decorative panel 30, and the first row position 12 and the lower mold core 11 are spaced apart to enclose a first molding cavity 13 for injection molding fasteners 31.

[0037] During operation, the lower mold core 11 is driven to move and reset, so that the top of the lower mold core 11 and the top of the first positioning are maintained at the same height, and the first row position 12 is displaced to one side of the lower mold core 11; then after the carbon fiber sheet is loaded into the lower mold core 11, the upper mold base 20 is driven to move downward toward the lower mold base 10, so that the upper mold core 21 and the lower mold core 11 are combined to stamp and form the carbon fiber decorative panel 30; furthermore, the lower mold core 11 is driven to move downward a certain distance, so that the top of the lower mold core 11 and the carbon fiber decorative panel 30 are spaced apart, and the first positioning is displaced away from the lower mold core 11 to enclose the first molding cavity 13; hot melt slurry is injected into the first molding cavity 13, and the fastener 31 can be injection molded at the bottom of the carbon fiber decorative panel 30.

[0038] Specifically, by setting the upper mold core 21, the lower mold core 11 and the first row position 12, the carbon fiber decorative panel 30 can be stamped and the fastener 31 can be injection molded at the bottom of the carbon fiber decorative panel 30 at the same time, without the need for bonding or welding operations; on the one hand, the connection firmness between the carbon fiber decorative panel 30 and the fastener 31 can be improved, thereby improving the use reliability and product yield of the carbon fiber decorative panel 30; on the other hand, the problem of welding spots on the surface of the carbon fiber decorative panel 30 during traditional welding can be solved, thereby improving the surface flatness of the carbon fiber decorative panel 30.

[0039] It should be noted here that the carbon fiber sheet is a thermoplastic carbon fiber composite sheet; the upper mold core 21 and the lower mold core 11 are both provided with a heating flow channel and a cooling flow channel (not shown in the figure). When the carbon fiber sheet is stamped and formed, the carbon fiber sheet can be heated by heating the upper mold core 21 and the lower mold core 11; heated to and maintained at a viscous flow temperature 10 to 20°C lower than the thermoplastic carbon fiber composite sheet, and then the stamping die is started to stamp the thermoplastic carbon fiber composite sheet, and then the heating is stopped; subsequently, the fastener 31 can be injection molded.

[0040] More specifically, there are at least two first rows 12 , and the two first rows 12 are adapted to be arranged on the left and right sides of the lower mold core 11 , so that during the injection molding operation, two fasteners 31 can be injection molded on the carbon fiber decorative panel 30 at the same time.

[0041] It should be noted that the carbon fiber decorative plate 30 is used to cover the surface of the vehicle center console, and the fastener 31 is used to be fixed to the hollow console by fasteners such as screws.

[0042] In some embodiments of the present application, the top of the lower mold core 11 is provided with a plurality of spurs 111, and the plurality of spurs 111 are arranged at equal intervals in front and back; when the upper mold core 21 and the lower mold core 11 are combined to stamp and form the carbon fiber decorative plate 30, the plurality of spurs 111 can stamp and form a plurality of grooves on the bottom of the carbon fiber decorative plate 30. By providing a plurality of spurs, a plurality of grooves can be formed on the bottom of the carbon fiber decorative plate 30, so that during subsequent injection molding, the plastic can be embedded in the grooves, thereby improving the connection firmness between the fastener 31 and the carbon fiber decorative plate 30, and the subsequent carbon fiber decorative plate 30 can be separated from the fastener 31, thereby improving the reliability and service life of the product.

The lower die base 10 can be installed with a first top plate 16 so as to move up and down, and the first top plate 16 is installed with a first oblique top rod 161; the first row 12 is provided with a first oblique top hole 121 running through its upper and lower surfaces, and the first oblique top rod 161 can be inserted into the first oblique top hole 121. The lower die base 10 can be installed with a second top plate 17 so as to move up and down, and the second top plate 17 is installed with a plurality of second top rods 171; when the second top plate 17 moves up and down, the top of the second top rod 171 can protrude from the top of the lower die core 11 to eject the carbon fiber decorative panel 30.

[0044] Furthermore, the upper mold base 20 is provided with a pouring port 22 and a main flow channel 23 connected to the pouring port 22; a secondary flow channel 122 is provided at the top of the first row 12, one end of the secondary flow channel 122 is connected to the main flow channel 23, and the other end is connected to the first molding cavity 13. Through the arrangement of the main flow channel 23 and the secondary flow channel, the hot melt slurry flows from the first row 12 into the first molding cavity 13, thereby avoiding the position of the carbon fiber decorative plate 30, ensuring that the surface flatness of the carbon fiber decorative plate 30 will not be affected when the fastener 31 is injection molded, thereby improving the yield of the product.

[0045] Preferably, first guide posts 24 are provided at the four corners of the bottom of the upper mold base 20, and first guide holes 14 are provided at the four corners of the top of the lower mold base 10; when the upper mold base 20 is displaced relative to the lower mold base 10 for mold closing, one first guide post 24 can be inserted into one first guide hole 14.
