Detailed Description

In order to make the technical means, creation features, achievement purposes and effects of the present invention easy to understand, the following embodiments are specifically illustrated in conjunction with the accompanying drawings.

Referring to fig. 1 to 4, the U-shaped pillow fastener mold provided in this embodiment includes a lower mold 1, a linear glue injection runner 2 is formed on an upper end surface of the lower mold 1, a plurality of lower mold cavities 3 formed by depressions are respectively arranged in an array in directions of two sides of the glue injection runner 2, the lower mold cavities 3 form a part of a cavity for molding a fastener 8, glue runner branches 4 equal in number to the lower mold cavities 3 are further provided on an upper end surface of the lower mold 1, and two ends of each glue runner branch 4 are respectively communicated to the glue injection runner 2 and one lower mold cavity 3.

Based on above-mentioned technical scheme, U type pillow fastener mould includes lower mould 1, is formed with injecting glue runner 2, a plurality of die cavity 3 down and a plurality of glue runner branch line 4 on the lower mould 1 for mould one shot operation can the shaping a plurality of fastener products, promotes work efficiency greatly, simultaneously, arranges 3 arrays in the both sides of injecting glue runner 2 with die cavity down, can guarantee that the sizing material pressure of every die cavity 3 inflow is unanimous basically.

In a preferred embodiment, as shown in fig. 2 in particular, the plane of the upper end surface of the lower mold 1 is taken as a reference horizontal plane, and in the direction away from the glue flow channel branch line 4, a slope 7 with gradually increasing depth is provided in each lower mold cavity 3, so that the slope 7 can rapidly fill the whole lower mold cavity 3 in production, and prevent the flow-resisting phenomenon of the glue due to cooling and pressure reduction of the glue.

As a further preferred embodiment, the cross-sectional shapes of the glue injection runner 2 and the glue runner branch 4 are both semicircular groove structures, specifically, the U-shaped pillow fastener mold further comprises an upper mold, and the lower end face of the upper mold is provided with a structure which is basically consistent with the glue injection runner 2, the glue runner branch 4 and the lower mold cavity 3 on the upper end face of the upper mold, so as to form an integral injection mold together after being mutually spliced. Meanwhile, the upper die is also provided with a plurality of glue flow passage main lines which are arranged in an array and communicated with the glue injection flow passage 2 so as to uniformly inject glue materials into the glue injection flow passage 2. Furthermore, the two ends of the glue injection runner 2 are in a uniform arc surface shape. Furthermore, in the directions of two sides of the glue injection runner 2, the number of the lower mold cavities 3 is eight, and each lower mold cavity 3 on one side of the glue injection runner 2 is opposite to the lower mold cavity 3 on the other side of the glue injection runner 2, that is, the corresponding glue runner branch lines 4 are on the same branch line, but not limited thereto.

In a further preferred embodiment, the cross-sectional diameter of the glue injection channel 2 is larger than the cross-sectional diameter of the glue channel branch 4. Further, a disc-shaped protrusion 5 for forming a mounting position of the hook and loop fastener 8 is formed in the lower mold cavity 3 in a raised manner, and a boss 6 for forming a through hole in the hook and loop fastener 8 is formed in the center of the disc-shaped protrusion 5 in a raised manner.

Specifically, as shown in fig. 3 and 4, the whole buckle 8 has a first plane 9, a first inclined plane 10, and a second plane 11 connected in sequence from the tail portion to the head portion. And the first inclined surface 9 corresponds to the inclined surface 7. The first inclined surface 9 has no influence on the function of the product itself, but can effectively achieve the effect described above for the inclined surface 7 during the injection molding process.

The foregoing is only a preferred embodiment of the present invention, which is illustrative, not limiting.
