Detailed Description

As shown in fig. 1-4, the present invention relates to a mold core ejection and demolding mold, which comprises a fixed mold base 1, a fixed mold plate 2, a fixed mold core 3, a movable mold plate 4, a movable mold core 5, a top plate 6, square iron 7, a movable mold base 8, a mold core 9, a wedge 10, a slide block 11, a top plate spring 12, a top rod 13, and a material pulling needle 14.

The fixed die holder 1 is fixed with the fixed die plate 2, the fixed die core 3 is fixedly arranged in the fixed die plate 2, the top surface of the movable die plate 4 is opposite to the bottom surface of the fixed die plate 2, the movable die core 5 is fixedly arranged in the movable die plate 4, a die cavity is formed between the fixed die core 3 and the movable die core 5, the bottom surface of the movable die plate 4 is connected with the movable die holder 8 through square iron 7, a slide block 11 is connected on the movable die plate 4 in a sliding way, the outer end of the slide block 11 is abutted against an inclined wedge 10, the inner end of the slide block 11 is sent into the die cavity, a magic tape can be placed between the inner end of the slide block 11 and the wall of the die cavity, the upper end of the inclined wedge 10 is fixed on the fixed die plate 2, a top plate 6 is movably arranged between the movable die plate 4 and the movable die base 8, a top plate spring 12 is arranged between the movable die plate 4 and the top plate 6, the lower end of, the mold core 9 can be detached together with the ejector rod 13 connected with the mold core, the lower end of the material pulling needle 14 is fixed on the movable mold plate 4, and the upper end of the material pulling needle 14 penetrates through the gap mold core 9 and then extends into a cold material well in the fixed mold core 3 so as to pull the cold material out of the flow channel.

As shown in fig. 5, in the present embodiment, the top rod 13 is a rectangular top rod, and the top end of the top rod 13 has a fixture block 131, and the fixture block 131 is clamped in the clamping groove 91 on the side wall of the mold core 9, so that the top end can be conveniently detached.

As shown in fig. 1 and 5, the working principle of the present invention is as follows:
