Examples

The utility model discloses a forming device of shoe tree rotating head 10, as shown in fig. 4 to 6, comprising a die 20 and a pouring cup 30, wherein the die 20 comprises an upper die 21 and a lower die 22, the upper die 21 and the lower die 22 enclose and form a cavity for forming the shoe tree rotating head 10, the die 20 is provided with a feeding runner 23, the pouring cup 30 pours materials into the die 20 through the feeding runner 23, as shown in fig. 1, 3 and 6, the formed shoe tree rotating head 10 comprises a first end 11 close to the feeding runner 23 of the die 20 and a second end 12 opposite to the first end 11, the bottom surface of the feeding runner 23 is provided with a buffer groove 231, corners of the buffer groove 231 are fillets, the step 13 of the bottom surface (the surface formed by the lower die 22 of the die 20) of the shoe tree of the existing rotating head 10 close to the first end 11 has a gas trapping phenomenon, and the main reason is that the materials flow into the cavity from the feeding runner 23, the flow velocity is faster at the position close to the first end 11, when the air passes through the position of the step 13, the material flow rushes along the direction, and an isolated space area is formed at the step 13, so that the air trapping phenomenon is formed. And the utility model discloses 23 bottom surfaces of feed runner buffer groove 231's setting provides buffer zone for the material stream that enters mould 20 for the material stream cushions here, thereby makes the material stream steadily flow into the die cavity, thereby effectively avoids the stranded gas phenomenon of step 13 department. And the fillet design of buffer groove 231 for the material flows more smoothly steady, thereby does benefit to the shaping, avoids producing the trapping phenomenon.

Referring to fig. 4, the pouring cup 30 includes a cup body 31 and a discharging flow passage 32 communicating with the cup body 31, the cup body 31 comprises a first side wall 311, a second side wall 312 opposite to the first side wall 311, a bottom wall 313 connecting bottom ends of the first side wall 311 and the second side wall 312, a top wall 314 connecting top ends of the first side wall 311 and the second side wall 312, a third side wall 315 and a fourth side wall (not shown in the figure) respectively connecting two side ends of the first side wall 311 and the second side wall 312, the discharging flow channel 32 is connected with the first side wall 311, wherein the included angle between the first side wall 311 and the top wall 314 is 25 degrees, the joints of the first side wall 311, the second side wall 312 and the bottom wall 313 are all in round transition, the discharging runner 32 is communicated with the feeding runner 23 of the mold 20, and the bottom surface of the discharging flow channel 32 and the bottom surface of the feeding flow channel 23 are in the same plane.

When the existing molding device is used for molding, materials in the pouring cup 30 cannot be completely injected into the mold 20 (materials are left), if no materials are left in the pouring cup 30, the whole molding device needs to be turned over by 90 degrees (anticlockwise turned by 90 degrees in the direction shown in fig. 3) and then poured, so that the existing molding device is limited and not beneficial to actual production operation. And the utility model discloses pouring cup 30's structural design, with whole device rotatory 65-70 degrees (the shown orientation anticlockwise rotation of figure 4 65-70 degrees) pour the material in pouring cup 30 and can flow in mould 20 completely, it is more convenient when so actually pouring, and can effectively avoid the remaining of material in pouring cup 30, more be favorable to the steady and the exhaust that the material flows simultaneously to guarantee the product quality, reduction in production cost.
