Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to an in-mold scraping mechanism for automobile safety system parts. Background Art

[0002] The structure of automobile safety system components is shown in Figure 1 The surface of the product is required to be free of burrs and hair chips. The product has hemming and bending features. The hemming position (the position circled by the ellipse) is prone to hair chips during molding. After molding, the hair chips will adhere to the surface of the product. It takes a lot of manpower to remove the hair chips through an external cleaning mechanism. Once the hair chips are integrated with the product surface, it will be difficult to remove them, thus affecting the quality of the product. For this reason, it is urgently necessary to develop a mechanism that can directly remove the hair chips at this position during the molding process, so as to improve the quality of the product.

[0013] It is further characterized by:

[0014] Each of the brush fixing blocks includes an upper fixing block and a lower fixing block, and each of the brushes includes an outer mounting end and inner bristles. After the upper fixing block and the lower fixing block are assembled, the outer mounting end is clamped, which ensures that the brush is assembled quickly and efficiently;

[0015] The upper surface of the lower die base is also provided with an upwardly convex stopper and limit block, and the stopper and limit block is used to limit the downward limit position of the stripper plate. When the brush is at the lowest position, there is a gap between the top of the product and the lower surface of the stripper plate to ensure that the product will not be damaged.

[0016] Preferably, the stop limit blocks are respectively arranged directly below the four corners of the stripping plate to ensure stable and reliable positioning without interfering with the normal arrangement of the product.

[0017] After adopting the above technical scheme, the brush is fixed on the downward convex brush fixing block corresponding to the upper mold assembly. When the mold is opened, the bristles are located at the upper part of the edging, and when the mold is closed, the bristles are located at the lower part of the edging. The upper mold base and the brush are driven up and down by an external lifting power, so as to scrape off the edging hair scraps on the product. It is arranged behind the edging forming station of the product, and a group of brush mechanisms are used to scrape off the edging hair scraps of the product. After that, the product undergoes the rear process to complete the overall structure stamping.

DETAILED DESCRIPTION

[0027] In-mold scraping mechanism for automotive safety system parts, see Figure 2-Figure 6 , which is suitable for products 100 with hemming 101 on both sides, and the hemming 101 needs to remove hair scraps, and includes an upper die base 10, an upper clamping plate 20, a stripping plate 30, a pair of brush fixing blocks 40, a pair of brushes 50, a lower die base 60, and a supporting positioning block 70;

[0028] A support and positioning block 70 is fixedly arranged in the central area of ​​the upper surface of the lower die base 60, and a product placement cavity is arranged on the upper surface of the support and positioning block 70. The lower surface of the product 100 is placed in the product placement cavity and positioned. The hemming 101 on both sides of the product 10 is respectively arranged in the peripheral areas on both sides. An upper clamping plate 20 and a stripping plate 30 are installed from top to bottom directly below the central area of ​​the upper die base 10. A brush fixing block 40 is fixedly arranged on the lower part of the stripping plate 30 corresponding to the peripheral area of ​​the hemming 101. The brush fixing block 40 faces the hemming 101. The inner side of the mold base 101 is shaped like the outer contour of the edging 101, and a brush 50 is installed on the inner surface of each brush fixing block 40. The bristles 51 of the brush 50 are arranged corresponding to the outer contour of the edging 101. The inner part of the bristles 51 of the brush 50 covers the area where hair scraps are generated on the edging 101 on the corresponding side. The upper mold base 10 drives the brush 50 to move up and down. When the brush 50 is in the highest position, the brush 50 is higher than the edging 101. When the brush 50 is in the lowest position, the brush 50 is lower than the edging 101.

[0029] In a specific embodiment, each brush fixing block 40 includes an upper fixing block 41 and a lower fixing block 42, and each brush 50 includes an outer mounting end 52 and inner bristles 51. After the upper fixing block 41 and the lower fixing block 42 are assembled, the outer mounting end 52 is clamped, which ensures that the assembly of the brush 50 is fast and efficient.

[0030] The upper surface of the lower die base 60 is also provided with a convex stop limit block 80, which is used to limit the downward limit position of the stripping plate 30. When the brush 50 is in the lowest position, there is a gap between the top of the product 100 and the lower surface of the stripping plate 30 to ensure that the product will not be damaged.

[0031] In a specific embodiment, the stop limit blocks 80 are respectively arranged directly below the four corners of the stripping plate 30 to ensure stable and reliable positioning without interfering with the normal arrangement of the product.

[0032] When the brush 50 is assembled, see Figure 6 The inner area of ​​the bristles 51 covers the entire outer edge surface of the edging of the product 100. The brush 51 is soft, ensuring that the surface of the product will not be damaged when moving up and down for cleaning. The main cleaning action is to move from top to bottom. The bristles 51 remove hair scraps from the surface of the edging 101 of the product 100 from top to bottom. The bristles 51 have multiple layers in the thickness direction.

[0033] Its working principle is as follows: the brush is fixed on the downward convex brush fixing block corresponding to the upper mold assembly. When the mold is opened, the bristles are located at the upper part of the edge, and when the mold is closed, the bristles are at the lower part of the edge. The upper mold base and the brush are driven up and down by an external lifting power to scrape off the hair scraps on the edge of the product. It is arranged behind the edge forming station of the product, and a group of brush mechanisms are used to scrape off the hair scraps at the edge position of the product. After that, the product undergoes the rear process to complete the overall structure stamping. The hair scraps are directly removed after they are generated, and there is no need to remove them laboriously at an external station, which reduces labor costs and ensures product quality.
