Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1 to 5, the present invention provides a technical solution:

example (b):

as shown in fig. 1-5, a door panel embossing die quick-change structure comprises two fixing tools 1, two square pins 2, an embossing die core 3 and an embossing die frame 4, wherein the two fixing tools 1 are connected with the embossing die core 3, the embossing die frame 4 is provided with two through holes 5, when the embossing die core 3 is matched with a cavity of the embossing die frame 4, the fixing tools 1 on the embossing die core 3 extend out of the two through holes 5, the embossing die frame 4 is further provided with an assembling groove 6, the assembling groove 6 is communicated with the through holes 5, and the assembling groove 6 is perpendicular to the through holes 5; the fixed tooling 1 is provided with a square groove 7, a connecting groove 8 matched with the square pin 2 is formed between the square groove 7 and the assembling groove 6, and the fixed tooling 1 is connected with the embossing die frame 4 through the square pin 2 and the connecting groove 8.

As shown in fig. 4, the fixing tool 1 has a T-shaped structure.

As shown in fig. 4 and 5, two first threaded holes 9 are formed in the fixing tool 1, two second threaded holes 10 corresponding to the two first threaded holes 9 are formed in the embossing mold core 3, and the fixing tool 1 is connected with the embossing mold core 3 through the first threaded holes 9, the bolts and the second threaded holes 10.

The number of the assembling grooves 6 is two, the two assembling grooves 6 are coaxially arranged, the two assembling grooves 6 are respectively communicated with the two through holes 5, and two ends of each assembling groove 6 are located on two sides of each through hole 5.

The working principle is as follows: the fixing tool 1 is connected with the embossing mold core 3 into a whole through the bolt, the first threaded hole 9 and the second threaded hole 10, and the embossing mold core 3 and the fixing tool 1 are integrally assembled in a cavity of the embossing mold frame 4. The fixed tool 1 extends out of the through hole 5 to enter the assembly groove 6, and the square groove 7 on the fixed tool 1 is partially higher than the assembly groove 6, so that a connecting groove 8 is formed between the square groove 7 and the assembly groove 6. After the fixing tool 1 is in place, the square pin 2 is inserted into the assembling groove 6, and the square pin 2 enters the connecting groove 8 through the assembling groove 6, so that the fixing tool 1 (the embossing mold core 3) is connected with the embossing mold frame 4.

When the embossing mold core 3 needs to be replaced, only the lower pin 2 needs to be taken down, the other embossing mold core 3 with the fixed tooling 1 needs to be replaced, and the square pin 2 is inserted again after the embossing mold core 3 is replaced, so that the replacement of the embossing mold core 3 can be completed.
