Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 8, the present embodiment provides an interchangeable insert for an injection mold for a front grille of an automobile, which includes a front mold insert 1 and a rear mold insert 2 disposed below the front mold insert 1, wherein a threaded hole 3 is formed in the top of the front mold insert 1, and the front mold insert 1 and a front mold can be fixedly assembled by a screw. The middle part of the lower part of the front mold insert 1 is in an upward triangular concave arrangement, the outer edge of the bottom of the front mold insert 1 is provided with a downward bulge 4, and the bulge 4 has the effect of forming a process groove 13 on the surface of a product, so that the appearance defect caused by the fact that a splicing line appears on the surface of the product is avoided. The top of the rear mold insert 2 is arranged in a triangular bulge mode, and the upper surface of the rear mold insert 2 is matched with the lower surface of the front mold insert 1. The back mould mold insert 2 includes casing 5 and is the slope and installs the activity in casing 5 and insert 6, the activity is inserted 6 and is the type setting of falling T, the activity is inserted and is provided with holding tank 7 in the casing 5 of 6 both sides, install spring 8 in the holding tank 7, 6 surfaces and the 5 inner walls butt of casing are inserted with the activity respectively at spring 8 both ends, and the activity is inserted 6 and is retreated under spring 8's elasticity, realizes the inclined hole and looses core. One side of the middle part of the movable insert 6 is provided with a limiting groove 9, a positioning insert 10 is arranged in the shell 5 corresponding to the limiting groove 9, and one end of the positioning insert 10 is clamped in the limiting groove 9 to prevent the movable insert 6 from falling off. The width of the upper part of the positioning insert 10 is smaller than the length of the limiting groove 9, so that the movable insert 6 has a certain movable space, and the stroke of the movable insert 6 in the housing 5 is ensured to be 3.5 mm.
The top of the movable insert 6 is flush with the surface of the shell 5, the product molded by the front mold insert 1 and the rear mold insert 2 is shown in fig. 7, and the surface of the product does not have a round hole and is used as a front grid of a low-profile.
