The fog lamp cover decorative strip structure for the automobile is mainly assembled with the fog lamp cover body for the automobile, plays a decorative role, is particularly suitable for strip-shaped parts and products similar to the fog lamp cover, wherein the assembly space is small, and the parts and the opponent parts are all products of an integrally injection-molded resin part, and are externally-installed decorative parts, so that the requirements on the performance of the appearance commodity of the products are very high.
The utility model provides a fog lamp shade trim structure for car, including main part 1, main part 1 has narrow body 2 and wide body 3 integrative constitution, whole main part 1 is crooked by narrow body 2 to wide body 3, be provided with first mounting base 4 and second mounting base 5 respectively on narrow body 2 and wide body 3, junction between narrow body 2 and wide body 3 is provided with the card and joins in marriage base 6, the base open slot 7 with main part 1 surface overlap joint has been seted up under the card joins in marriage base 6, base open slot 7 and main part 1 overlap joint junction position department has even thickness, base open slot 7 outwards forms flaring face 8 from main part 1 surface that has even thickness, here is base open slot 7 of prior art as shown in fig. 2, here base open slot 7 position is the position of sideslip piece loose core, can see this base open slot 7 and main part 1 overlap joint causes main part 1 to design inhomogeneous, the material flow unsteady when the wall thickness inequality can lead to the shrink mark when the injection molding machine, thereby lead to the outward appearance face to appear, as shown in fig. 3, and the base open slot 7 has even thickness 7 forms flaring face 8 outwards from main part 1 surface from having even thickness, this open slot 7 has the good appearance face of surface, this appearance of the surface is avoided the good appearance of the surface to be formed to the surface of the product, this open slot is formed.
As shown in fig. 4, the base open slot 7 in the prior art is shown in fig. 4, where the base open slot 7 does not have a corresponding side reinforcement rib 10, so that the direction of the relevant side wall 9 is inconsistent with the direction of the product material flow, and a sink mark is easily formed on the appearance surface during injection molding, as shown in fig. 5, while the structure is that the side walls 9 are provided on both sides of the base open slot 7, the side reinforcement ribs 10 are provided on the side walls 9, and the directions of the melt material flows of the side reinforcement ribs 10 and the side walls 9 during injection molding are consistent, so that the side reinforcement ribs 10 are provided along the melt material flow direction, thereby preventing the appearance defect caused by shrinkage, and simultaneously enabling the melt material flow directions of the side reinforcement ribs 10 and the side walls 9 to be consistent during injection molding, and the sink mark is easily not formed on the appearance surface during injection molding.
As shown in fig. 7, the first mounting base 4 includes a first base body 11, the lower end of the first base body 11 has an end leg 12, two end legs 12 of the first base body 11 overlap the narrow body 2, and a through-flow opening 13 is provided between the two end legs 12 and the narrow body 2. The through-flow opening 13 at the lower end of the first mounting base 4 of the automotive fog lamp cover electroplating bright strip is mainly used for outflow of electroplating bath solution, positioning and stable ejection of the inclined top of a die, so that the situation that the electroplating bath solution cannot flow out and can cause bath solution pollution of a factory is prevented, as shown in fig. 6, the first base body 11 in the prior art is provided, two end pins 12 and a narrow body part 2 can be seen to be closed, and no corresponding through-flow opening 13 exists, so that the electroplating bath solution cannot flow out and can cause bath solution pollution of the factory.
As shown in fig. 8, the positioning cross rib 14 is directly arranged on the surface of the wide body 3, so that turbulence is generated when the material flows through the positioning cross rib when in injection molding because of nonuniform conversion of wall thickness, shrinkage of the polymer plastic is caused when cooling, and thus the performance of the appearance commodity is reduced, as shown in fig. 9, the second mounting base 5 of the automobile comprises a second base body 15, the second base body 15 is lapped on the wide body 3, the positioning cross rib 14 is arranged on the second base body 15, the positioning cross rib 14 is directly arranged on the second base body 15 and not contacted with the wide body 3, so that shrinkage is prevented, positioning and mounting are facilitated, and the appearance commodity performance is prevented from being reduced, and as shown in fig. 10, the first mounting base 4 and the second mounting base 5 are both provided with base holes 16, and inner grooves 17 are formed in the base holes 16, so that waste is convenient to exit when self-nailing assembly is performed by using the inner grooves 17, and the whole installation and locking are facilitated; as shown in fig. 11, the side of the base hole 16 of the second base body 15 is provided with column position reinforcing ribs 18, where when there is no column position reinforcing rib 18, when the automatic assembly is performed on line, the torque of the automatic screw driving machine is relatively large, the risk of column cracking of the base hole 16 of the second base body 15 is easy, and by setting the column position reinforcing ribs 18, the column position strength is increased, and the installation torque is prevented from being excessively large to crack.
As shown in fig. 12, the flange 19 of the main body 1 in the prior art is directly contacted with the surface of the opposite piece, thus easily forming poor matching, as shown in fig. 13, while the flange 19 is arranged on the peripheral surface of the upper end of the main body 1 in the patent, and a plurality of convex points 20 are uniformly distributed on the flange 19, so that the opposite piece is propped up by the convex points 20 during installation, the whole surface contact is avoided, and the poor matching is prevented by positioning in a point contact mode.
As shown in fig. 14, the prior art is not only provided with a shrink-proof structure, but is directly provided with a lap joint pin on the edge side of the narrow body 2, so that the side wall 9 of the relevant base can form a sharp corner structure 22 at the position close to the flanging 19 at the edge side, the hand is easy to be cut during the bench work during the die work, and meanwhile, the shrink-proof structure is not provided with a shrink-proof structure, so that shrink is easy to occur on the appearance surface, as shown in fig. 15, but the present patent is provided with a shrink-proof lap joint pin 21 between the first base body 11 and the narrow body 2, the shrink-proof lap joint pin 21 is locally reduced in thickness, and the shrink-proof lap joint pin 21 is lapped on the middle part of the edge of the narrow body 2, so that shrink and poor appearance of die sharp steel are prevented.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the scope of the invention as defined in the accompanying claims.
