[0022] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0023] like Figures 1 to 6 As shown, a die-casting mold with balanced ejection comprises a base 1, a top mold mounting seat 2 and two movable seats 3. The base 1 is connected to the top mold mounting seat 2 through a supporting column. A top mold 4 is fixedly mounted on the bottom side of the top mold mounting seat 2. A bottom mold 5 is fixedly mounted on the top sides of the two movable seats 3. The bottom mold 5 is adapted to the size of the top mold 4. A cavity is arranged inside the bottom mold 5. Two pushers 6 for driving the movable seats 3 to move are fixedly mounted on one side of the two movable seats 3. The output ends of the four pushers 6 are connected to the top mold mounting seat 2. A plurality of guide columns 7 are fixedly connected to one side of the base 1. A top plate 8 is fixedly connected to the outer surface of the plurality of guide columns 7. A plurality of ejector rods 9 are fixedly connected to the top side of the top plate 8. The height of the rod 9 is determined according to the product, and if the product has a portion protruding toward the edge, a push rod 9 can also be set at a position corresponding to the protruding portion of the product, so that the push rod 9 can better eject the product. After the product is processed by the die-casting mold, the pusher 6 is started. At this time, the movable seat 3 will drive the bottom mold 5 to move downward, so that the bottom mold 5 is separated from the top mold 4. As the bottom mold 5 moves, the bottom mold 5 and the push rod 9 are in a relative position. At this time, several push rods 9 will simultaneously lift up the product located inside the cavity of the bottom mold 5. Several push rods 9 increase the contact area with the product, so that the force of the product can be evenly distributed to several push rods 9, avoiding product damage caused by excessive stress concentration.

[0024] As an optional technical solution of the present utility model, four through holes 10 are opened on one side of the top mold 4, and four installation cavities 11 are opened on one side of the bottom mold 5. The main part of the push member 6 is located inside the installation cavity 11, and the output end of the push member 6 passes through the inside of the through hole 10. The diameter of the output end of the push member 6 is smaller than the diameter of the through hole 10, so that the output end of the push member 6 can move smoothly.

[0025] As an optional technical solution of the present invention, a feed port 12 is provided on the top mold 4 , and the bottom end of the feed port 12 is connected to the cavity through a flow channel, so that external raw materials can enter the cavity of the bottom mold 5 through the feed port 12 .

[0026] As an optional technical solution of the present utility model, the bottom side of the movable seat 3 is fixedly connected to a limiting baffle 13, the top plate 8 is located inside the space formed by the two movable seats 3, the width of the top plate 8 is smaller than the minimum distance between the two limiting baffles 13, and after the top mold 4 is connected to the bottom mold 5, the top side of the limiting baffle 13 fits with the bottom side of the top plate 8.

[0027] As an optional technical solution of the utility model, the guide column 7 passes through the bottom mold 5 and the top mold 4, the top end of the guide column 7 is connected to the top mold mounting base 2, and the bottom mold 5 is slidably connected to the guide column 7, so that the bottom mold 5 can move smoothly in the vertical direction.

[0028] As an optional technical solution of the present invention, the push rod 9 passes through one side of the bottom mold 5 and extends to the inside of the cavity of the bottom mold 5. Several push rods 9 are evenly distributed in an array inside the cavity, so as to evenly distribute the force on the finished product inside the cavity.

[0029] As an optional technical solution of the present invention, the pushing member 6 is an electric push rod or a hydraulic cylinder.

[0030] A die-casting mold with balanced ejection, the working principle is as follows:

[0031] After the product is processed by the die-casting mold, the pusher 6 is started. At this time, the movable seat 3 will drive the bottom mold 5 to move downward, so that the bottom mold 5 is separated from the top mold 4. As the bottom mold 5 moves, the bottom mold 5 and the ejector rod 9 are in a relative position. At this time, the product located inside the cavity of the bottom mold 5 will be lifted up at the same time by several ejector rods 9.

[0032] To sum up, the die-casting mold with balanced demolding is arranged through the coordination of the moving seat 3, the top mold 4, the bottom mold 5, the pushing member 6, the guide column 7, the top plate 8 and the ejector 9. After the product is processed by the die-casting mold, the bottom mold 5 can be pushed downward by the pushing member 6. At this time, the finished product located inside the bottom mold 5 can be lifted up by a number of ejector rods 9. Because a plurality of ejector rods 9 are provided, and the plurality of ejector rods 9 are evenly distributed inside the cavity of the bottom mold 5, the force on the product can be more evenly applied during the process of lifting the product through a plurality of ejector rods 9, so that the demolding work is in a balanced state, thereby avoiding the deformation of the product during the demolding process and ensuring that the product quality is relatively good.
