Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 and 2: a tube-pushing type die capable of realizing secondary ejection comprises a fixed die taking-off plate 1, a fixed die plate 2 is arranged below the fixed die taking-off plate 1, a fixed die core 9 is arranged in the fixed die plate 2, the die further comprises a movable die taking-off plate 8, an ejector rod bottom plate 7, an ejector rod plate 6, square iron 5, a movable die bottom plate 4 and a movable die plate 3 are sequentially arranged above the movable die taking-off plate 8, a movable die core 10 is arranged in the movable die plate 3, and the fixed die core 9 and the movable die core 10 can form a die cavity during die assembly,
the ejector rod bottom plate 7 is provided with a movable mold push tube 14, a movable mold core shaft 13 is movably connected in the movable mold push tube 14, the movable mold core shaft 13 is connected with a stop block 12, the side wall of the movable mold push tube 14 is provided with long holes distributed along the length direction of the movable mold push tube, the end part of the stop block 12 is connected in the long holes in a sliding manner, a movable mold limiting groove 15 is arranged in the movable mold plate 3, the stop block 12 is positioned in the movable mold limiting groove 15, the top ends of the movable mold push tube 14 and the movable mold core shaft 13 are positioned in the movable mold core 10 and form a part of a mold cavity,
the utility model discloses a fixed mould is got and is connected with fixed mould ejector sleeve 17 on the bottom face of paying board 1 is got to the fixed mould, swing joint has fixed mould dabber 18 in the fixed mould ejector sleeve 17, the top of fixed mould dabber 18 is provided with spacing step 19, just spacing step 19 sliding connection is in the fixed mould spacing groove 20 of seting up in fixed die plate 2, still is provided with spring 21 between the pay board 1 is got to the top of fixed mould dabber 18 and fixed mould simultaneously, the bottom of fixed mould ejector sleeve 17 and fixed mould dabber 18 is located fixed mould core 9 and forms a part of die cavity.
The utility model discloses can realize push away tubular mould of ejecting action of secondary's working process as follows: when the die is closed, the fixed die core 9 and the movable die core 10 together form a die cavity, and the movable die push pipe 14, the movable die core shaft 13, the fixed die push pipe 17 and the fixed die core shaft 18 together also form part of the die cavity; a molding machine is used for filling the material in a molten state into the cavity, the material is cooled to form a product (shown in figure 1),
