[ detailed description ] embodiments

For a further understanding of the objects, technical effects and technical means of the present invention, reference will now be made in detail to the following description taken in conjunction with the accompanying drawings.

Referring to fig. 1 to 3, fig. 1 is a schematic view illustrating an ejection structure of a die casting mold according to the present invention, fig. 2 is a schematic view illustrating another angle of the ejection structure of the die casting mold according to the present invention, and fig. 3 is a schematic view illustrating an ejection plate in the ejection structure of the die casting mold according to the present invention.

In this embodiment, in the ejection structure of a die casting mold, the die casting mold is matched with a die casting machine to use a die casting molding workpiece, and the ejection structure includes:

an upper thimble plate 10;

the lower ejector plate 11 is arranged below the upper ejector plate 10 and fixedly connected with the upper ejector plate 10, and an ejector pin of the die-casting die is arranged in the upper ejector plate 10 and the lower ejector plate 11 and used for ejecting a die-cast workpiece;

the ejector plate 12 is arranged below the lower ejector plate 11, the ejector plate 12 is fixedly connected with the lower ejector plate 11, and a plurality of K.O holes 13 are formed in the ejector plate 12 to allow ejector rods of a die-casting machine to pass through.

Further, in order to firmly connect the ejector plate 12 with the lower ejector plate 11, the lower ejector plate 11 and the ejector plate 12 are provided with tool grooves, and the tool grooves are correspondingly provided with tool-shaped positioning pins 16 to fixedly connect the lower ejector plate 11 and the ejector plate 12.

Furthermore, a T-shaped groove is formed in the lower ejector plate 11, an inverted T-shaped groove 15 is formed in the ejector plate 12, and the T-shaped groove and the inverted T-shaped groove 15 are vertically and correspondingly connected to form an i-shaped groove for accommodating an i-shaped positioning pin 16.

Further, please refer to fig. 5 and fig. 6, wherein fig. 5 is a schematic view illustrating a locating pin in an ejection structure of a die casting mold according to the present invention, and fig. 6 is a schematic view illustrating another angle of the locating pin in the ejection structure of the die casting mold according to the present invention. One end of the I-shaped positioning pin 16 extends out of the ejector plate 12 and the lower ejector plate 11, and the extending end is provided with a threaded hole 17, and the threaded hole 17 facilitates installation and removal of the I-shaped positioning pin 16.

Further, please refer to fig. 4, which is a schematic view illustrating another angle of the ejector plate in the ejection structure of the die casting mold according to the present invention. The periphery of the ejector plate 12 is provided with clearance 14 so as to adapt to the positions of support columns of different die-casting molds and allow the support columns of the die-casting molds to pass through.

The K.O holes 13 are uniformly distributed around the ejector plate 12, so that ejector rods of a die casting machine uniformly and forcefully eject out the ejector plate 12, and the ejector plate 12 drives the upper ejector plate 10 and the lower ejector plate 11 to be ejected in a balanced manner.

When the ejection structure of the die-casting die works, after the die-casting die performs die-casting on a workpiece, the die is opened, an ejector rod of the die-casting die pushes an ejector plate 12 upwards to eject, the ejector plate 12 drives a lower ejector pin plate 11 and an upper ejector pin plate 10 to eject upwards, and simultaneously the upper ejector pin plate 10 and the lower ejector pin plate 11 drive ejector pins to eject the die-cast workpiece upwards.

Compared with the prior art, the ejection structure of the die-casting die has the advantages that the ejection plate 12 is additionally arranged below the lower ejector plate 11 of the die-casting die, and the plurality of K.O holes 13 are formed in the ejection plate 12 and used for ejector rods of a die-casting machine to pass through, so that the interference between the ejector rods of the die-casting machine and a die structure is avoided, the die is conveniently erected, and the working hours are saved.
