Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in detail below in with reference to the accompanying drawings and embodiments.

The fixing device for kinds of steel members in aluminum alloy die-casting die of the utility model, as shown in figure 1-2, comprises a connecting rod 3 arranged on a movable die 1, an actuator 4 driving the connecting rod 3 to move vertically, and an insert 5 arranged on a fixed die 2, when the movable die 1 and the fixed die 2 are closed, the actuator 4 drives the connecting rod 3 to enable the insert 5 to fix the steel member, the actuator 4 is an oil cylinder, wherein,

as shown in fig. 3 to 6, the connecting rod 3 includes a connecting portion 31 and a driving portion 32, the insert 5 includes an insert body 51 and at least two ejector pins 52, the insert body 51 is provided with a guide hole 53 for guiding the ejector pins 52 to move, the ejector pins are moved along the radial direction of the insert body 51 by the driving portion 32 of the connecting rod 3, and the steel is held by the ejector pins 52 and friction force.

Specifically, the driving portion 32 of the connecting rod 3 is a trapezoid structure, and the end of the thimble 52 is provided with a bevel edge matching the trapezoid structure. It can be understood that when the thimble 52 is disposed in the guiding hole 53, after the driving portion 31 contacts with the inclined surface of the thimble 52, the thimble 52 moves along the guiding hole 53 in a radial direction due to the guiding function of the inclined surface, thereby fixing the steel member.

In order to enable the driving part 32 to accurately reach the middle of the two ejector pins 52, the connecting part 31 is provided with an -th guide 33, the insert body 51 is provided with a -th guide groove 54 matched with the -th guide 33, the driving part 32 can accurately reach a designated position when moving towards the ejector pins by matching the -th guide 33 with the -th guide groove 54. preferably, the -th guide 33 is a cylinder, in the embodiment, the connecting part 31 is further provided with a second guide 34 for preventing the connecting part 31 from rotating, the insert body 51 is provided with a second guide groove 55 matched with the second guide 34, preferably, the second guide 34 is flat, therefore, the second guide groove 55 is also flat, the driving part 32 can accurately reach between the two ejector pins 52 by arranging the -th guide 33 and the second guide 34, and the inclined edge of the driving part 32 corresponds to the inclined edge of the ejector pins 52.

In , the outward end of pin 52 has an arcuate configuration that acts as a guide to guide pin 52 inward as it is inserted into insert 5 without impeding the insertion of the steel.

The utility model discloses when using, as shown in fig. 2, connecting rod 3 sets up on movable mould 1, mold insert 5 sets up on cover half 2, and connecting rod 3 and mold insert 5 are corresponding, cover the steel part on mold insert 5, movable mould 1 moves down carries out the compound die, after the compound die, actuator 4 drive connecting rod 3 moves down, make guide 33 and second guide 34 get into guide way 54 and second guide way 55 in, reach the position shown in fig. 6, connecting rod 3 continues to move down, through the mutually supporting of the hypotenuse of drive division 32 and thimble 52, provide the thrust that moves to both sides for thimble 52, make thimble 52 move to both sides, withstand the inner wall of steel part, and then fix the steel part, reach the position shown in fig. 5, during the die sinking, actuator 4 drive connecting rod 3 moves up, thimble 52 loses thrust, then movable mould 1 moves up, the die sinking is accomplished, take out the product.
