Description

Technical Field

[0001] The utility model relates to the technical field of die casting, in particular to a quick die change device for a die casting machine. Background Technique

[0002] In the die casting industry, the replacement of dies is an inevitable part of the production process. The traditional die replacement method usually adopts a hoisting method, that is, the die is lifted to the installation position of the die casting machine by a hoisting device, and then the worker manually aligns and installs the die.

[0003] However, this traditional die change method has significant problems. Due to the lack of an effective limiting device when hoisting the die, the die is prone to shaking or deviation during the lifting and moving process, resulting in the die being unable to accurately align with the installation position of the die casting machine. This not only increases the difficulty for workers to align the die, but also may cause collisions and damage between the die and the die casting machine, reducing the production efficiency and the service life of the die, being inconvenient to operate, and bringing many troubles to people. Therefore, based on the above disadvantages, a quick die change device for a die casting machine is now introduced to improve this situation. Content of the Utility Model

[0016] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a rapid die-changing device for a die-casting machine, including tooling 1 and fixed mold 2.

Positioning rods 6 are arranged at the four corners on the left side of the tooling 1. A motor 7 is screwed to the top end of the inner cavity of the tooling 1. A first gear 8 is installed at the output end of the lower surface of the motor 7. One end of a driving rod 9 is rotatably connected to the central position on the right side of the inner cavity of the tooling 1 through a bearing, and the other end of the driving rod 9 is fixedly connected to a three-jaw chuck 10. A second gear 11 is installed on the outer wall of the driving rod 9, and the second gear 11 is meshed with the first gear 8. One ends of movable jaws 12 are installed on the left circumference of the three-jaw chuck 10, and the other ends of the movable jaws 12 are installed with fixed rods 13. A limiting mechanism 14 is assembled at the bottom end of the inner cavity of the tooling 1.

[0017] As a preferred solution, further, the positioning rod 6 is inserted into the positioning hole 3, and the fixed rod 13 is inserted into the fixing hole 5.

[0018] As a preferred solution, further, the limiting mechanism 14 includes a guide rod 141. The guide rod 141 is arranged at the bottom end of the inner cavity of the tooling 1. A connecting rod 142 is sleeved on the outer wall of the guide rod 141. Clamping holes 143 are symmetrically opened on the left and right sides at the top end of the inner cavity of the tooling 1. A rubber clamping ball 144 is installed at the top end of the connecting rod 142, and the rubber clamping ball 144 is clamped with the clamping hole 143. The bottom end of the connecting rod 142 extends out of the lower surface of the tooling 1 and is installed with a base 145. Balls 146 are installed on the upper surface of the base 145 from front to back. The fixed mold 2 can be conveniently fine-tuned in the front, back, left, and right directions on the base 145 according to the use requirements through the balls 146.

[0019] As a preferred solution, furthermore, the rubber ball-catching member 144 and the ball-catching hole 143 are matched with each other and their positions correspond to each other.

[0020] As a preferred solution, furthermore, the distance that the base 145 moves left and right is much greater than the length of the positioning hole 3.

[0021] The electrical components mentioned in this solution are all prior arts, and the model is only one of them. As long as the electrical components that can meet the requirements in this solution can be used.

[0022] Through the personnel in this field, all the electrical components in this case are connected to their adapted power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, refer to the sequence of the electrical components working successively in the following working principle to complete the electrical connection. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no further description of the electrical control will be made. The specific work is as follows.

[0023] When hoisting the fixed mold 2, first move the base 145 forcefully to the left. The base 145 will drive the ball 146, the connecting rod 142 and the rubber clamping ball 144 to move to the left together. During the leftward movement of the rubber clamping ball 144, the rubber clamping ball 144 will be squeezed and deformed. And when the base 145 moves away from below the tooling 1, the rubber clamping ball 144 will snap into the inner cavity of the clamping hole 143. By the mutual clamping between the rubber clamping ball 144 and the clamping hole 143, the position of the base 145 can be fixed. At this time, place the hoisted fixed mold 2 on the base 145, finely adjust the position of the fixed mold 2 back and forth so that the positioning hole 3 is aligned with the positioning rod 6, push the fixed mold 2 to the right, insert the positioning rod 6 into the inner cavity of the positioning hole 3 and the fixed mold 2 fits with the tooling 1. Turn on the motor 7, and the motor 7 will drive the first gear 8 to rotate. The rotating first gear 8 will cause the second gear 11 meshing with it to drive the driving rod 9 and the three-jaw chuck 10 to rotate together. Since multiple movable jaws 12 are all meshed on the outer wall of the three-jaw chuck 10, when the three-jaw chuck 10 rotates, it can cause multiple movable jaws 12 to drive the fixed rod 13 to move outward together. This is the same as the working principle of the three-jaw chuck fixture in the prior art and will not be elaborated here. When the fixed rod 13 moves outward and is inserted into the inner cavity of the fixing hole 5, by the mutual locking between the fixed rod 13 and the fixing hole 5, the position of the fixed mold 2 is fixed, that is, the hoisting of the fixed mold 2 is completed. Finally, move the base 145 to the right and retract it below the tooling 1 to avoid affecting normal die-casting operations. This device adopts the way of limited movement. When hoisting the mold, it can ensure that the position and height between the mold and the tooling are the same, avoid the situation of the mold shaking and shifting, not only reduces the difficulty for workers to align the mold, facilitates the disassembly and assembly of the mold, but also can avoid the mold from colliding, improves the production efficiency and the service life of the mold, is easy to operate, flexible to use, has strong practicability and is suitable for popularization.
