Referring to fig. 1 in combination with fig. 2, in order to provide an embodiment of the present invention, an automatic precision stamping die in the embodiment is used for stamping a product 12, the automatic precision stamping die in the embodiment includes an upper mold plate 10, a punch fixing plate 20, a lower mold fixing plate 30, and a lower mold plate 40, and each component of the automatic precision stamping die is further described below:

the punch head 15 is arranged on the punch plate 20;

wherein:

a die core 11 corresponding to the punch 15 is arranged on the lower die fixing plate 30, and a product 12 to be punched is placed on the die core 11; a cavity is arranged in the product 12, and openings 13 communicated with the cavity are arranged on two sides of the product; two sides of the mold core 11 are respectively provided with a slideway with the same structure in the radial direction, and the slideways are connected with core-pulling chains 14 corresponding to the shape and the size of the cavity in a sliding way; before the upper die plate 10 drives the punch 15 to punch, the core pulling chains 14 on two sides of the die core 11 slide along the slide ways and synchronously slide into the cavity from the openings 13 on two sides of the product 12 to fill the cavity, so that the product 12 is prevented from deforming when the upper die plate 10 drives the punch 15 to perform differential pressure.

Furthermore, the slide ways are all provided with a core-pulling pushing structure which pushes the core to move along the slide ways. Specifically, push away structure looses core includes: a slide 101 and a push block 102, wherein:

the slide block 101 is connected in the slide way in a sliding way, one end of the slide block is connected with the core-pulling chain 14, and the other end of the slide block is provided with a first inclined surface 1002 protruding out of the lower die fixing plate 30; the push block 102 is connected in the slideway in a sliding way, one end of the push block 102 is fixedly connected with the slide block 101, and the other end of the push block 102 extends out of the lower die fixing plate 30 along the horizontal direction and is sleeved with an elastic piece 103; one end of the elastic element 103 is fixedly connected with the push block 102, and the other end is abutted with the outer side wall of the lower die fixing plate. Specifically, the elastic member 103 is a spring.

Further, the punch retainer 20 is further provided with two side edges 104 for driving the slider 101 to move, the two side edges 104 are located on two sides of the punch 15, one end of each side edge 104 is fixedly connected to the punch retainer 20, the other end of each side edge 104 is provided with a second inclined surface 1001 corresponding to the first inclined surface 1002 in shape and size, and the second inclined surfaces 1001 are parallel to the first inclined surfaces 1002; when the upper mold plate 10 moves downward, the side blade 104 is driven to move downward until the second inclined surface 1001 of the side blade 104 abuts against the first inclined surface 1002 and forms a pushing force to the first inclined surface 1002 to move toward the product 12.

Principle of the core back chain 14 sliding into the cavity of the product 12:

when the upper die descends, the punch 15 and the side blade 104 on the punch holder 20 are driven to descend, and the height of the side blade 104 is higher than that of the punch 15, so that the abutment between the second inclined surface 1001 of the side blade 104 and the first inclined surface 1002 of the slider 101 is earlier than that between the punch 15 and the product 12, that is, when the second inclined surface 1001 of the side blade 104 and the first inclined surface 1002 of the slider 101 are abutted, the upper die plate 10 continues to descend, at this time, the side blade 104 generates a vertical gravity and a horizontal thrust to the direction of the product 12 on the slider 101, when the thrust is greater than the pressure, the side blade 104 pushes the slider 101 to move towards the direction of the product 12, the slider 101 simultaneously drives the core pulling chains 14 on both sides of the die core 11 to slide along the slide way and synchronously slide into the cavity from the openings 13 on both sides of the product 12 for filling the cavity, at this time, the upper die continues to descend until the punching step is completed on the, the push block 102 is in a spring compression state due to moving towards the mold core 11;

principle of the core back chain 14 sliding out of the cavity of the product 12:

when the upper die moves upwards, the punch 15 and the side edge 104 on the punch holder 20 are driven to move upwards, and at the moment, the spring on the push block 102 recovers the shape, so that an outward horizontal pulling force is formed on the push block 102, the push block 102 moves outwards along the slide way, and the slide block 101 is driven to draw out the core pulling chain 14 filled in the cavity of the product 12.

It can be known to synthesize the above-mentioned, this application adopts chain 14 to loose core to replace driven profile modeling plug, utilize slider 101 of the ejection structure of loosing core to promote chain 14 of loosing core to slide and push it in the cavity of product 12, play the effect that prevents product 12 and warp under the punching press of drift 15, when product 12 accomplishes the punching press, cope match-plate pattern 10 goes upward, drive drift 15 and product 12 separation, simultaneously, the ejection structure of loosing core drives chain 14 of loosing core and outwards slides and takes it out from the cavity of product 12, degree of automation is high, reduce workman's intensity of labour, improve the operating efficiency of mould punching press.

The above description is only for the preferred embodiment of the present invention, and the structure is not limited to the above-mentioned shape, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
