[0011] Preferably, a positioning hole is provided on the bottom surface of the first convex mold.

[0012] Preferably, a positioning block is provided below the positioning hole, and the positioning block is fixedly connected to the top surface of the base plate.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the utility model, the slab is placed on the first punch, and then the die is pressed by an external hydraulic cylinder, and the first punch is moved downward to make the second punch protrude from the connecting groove. The slab is drawn by closing the die, the first punch and the second punch. After forming, as the die is lifted and separated, the first punch rises and the second punch is separated from the formed part in the connecting groove. The first spring lifts the top block to eject the shaped part and separate it from the first punch, so that the operator can quickly remove the shaped part, which effectively improves the drawing processing efficiency of the utility model.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] like Figure 1-4 As shown, the utility model provides a drawing die for automobile cover parts that is easy to take out materials, including a die 1, a first punch 2 is arranged below the die 1, a bottom plate 3 is arranged below the first punch 2, a connecting groove 24 is opened through the center of the top surface of the first punch 2, the inner wall of the connecting groove 24 is movably connected to the second punch 4, the bottom end of the second punch 4 is fixedly connected to the top surface of the bottom plate 3, first contraction grooves 241 are opened on both sides of the inner wall of the connecting groove 24, the inner wall of the first contraction groove 241 is movably connected to a top block 242, and a first spring 243 is fixedly connected between the bottom end of the top block 242 and the inner wall of the first contraction groove 241.

[0025] The following is a detailed description of the specific settings and functions of this embodiment. The slab is placed on the first punch 2, and then the die 1 is pressed by an external hydraulic cylinder, and the first punch 2 is moved downward to make the second punch 4 protrude from the connecting groove 24. The slab is drawn by combining the die 1, the first punch 2 and the second punch 4. After forming, as the die 1 is lifted and separated, the first punch 2 rebounds and rises, so that the second punch 4 is separated from the formed part in the connecting groove 24. The first spring 243 lifts the top block 242 to eject the formed part from the first punch 2, thereby facilitating the operator to quickly remove the formed part, thereby effectively improving the drawing processing efficiency of the utility model.

[0026] Example 2

[0027] like Figure 1-4 As shown, a movable hole 11 is provided on the top surface of the die 1, and a positioning guide rod 21 is movably connected to the inner wall of the movable hole 11, and the bottom end of the positioning guide rod 21 is fixedly connected to the top surface of the first punch 2, and a fixed rod 22 is fixedly connected to the top surface of the first punch 2, and a placement groove 23 is provided on the outer wall of the fixed rod 22. A movable groove 12 is provided on the bottom surface of the die 1, and a second contraction groove 26 is provided on the bottom surface of the first punch 2, and a connecting rod 32 is movably connected to the inner wall of the second contraction groove 26, and the bottom surface of the connecting rod 32 is fixedly connected to the top surface of the base plate 3, and a second spring 27 is fixedly connected between the top end of the connecting rod 32 and the inner wall of the second contraction groove 26. A positioning hole 25 is provided on the bottom surface of the first punch 2, and a positioning block 31 is provided below the positioning hole 25, and the positioning block 31 is fixedly connected to the top surface of the base plate 3.

[0028] The effect achieved by the entire embodiment is that, through the setting of the fixing rod 22 and the placement groove 23, it is convenient for the user to place the slab, and as the die 1 is pressed down, the slab on the placement groove 23 is separated from the fixing rod 22 and fits with the surface of the first punch 2, and through the setting of the positioning guide rod 21, the downward movement of the die 1 is limited and guided to ensure the accuracy of the mold closing, and through the setting of the second spring 27 and the connecting rod 32, after the die 1 is separated from the mold, the rebound of the second spring 27 is used to lift the first punch 2, so that the second punch 4 is initially separated from the molded part in the connecting groove 24, thereby facilitating the subsequent secondary separation of the molded part from the first punch 2.

[0029] The usage and working principle of this device: When in use, place the slab in the placement slot 23 of the fixed rod 22, and then press the die 1 through the external hydraulic cylinder. As the die 1 is pressed down, the slab on the placement slot 23 is separated from the fixed rod 22, and at the same time, the first punch 2 is moved down to make the second punch 4 protrude from the connecting slot 24. The slab is drawn and formed by the combination of the die 1, the first punch 2 and the second punch 4. After forming, as the die 1 is lifted and the mold is separated, the first punch 2 rebounds and rises, so that the second punch 4 is separated from the formed part in the connecting slot 24, and the first spring 243 lifts the top block 242 to eject the formed part from the first punch 2, so that the operator can quickly remove the formed part.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
