As a further solution of the present invention: the punch is provided with a punch slot matching the punch, and when the punch contacts the die, the punch is inserted into the matching punch slot after completing the punching work.

As a further solution of the present invention: guide rods are installed on both sides of the lower mold base, guide holes are provided on both sides of the upper mold base, the guide rods are inserted into the guide holes, and the punch slides along the guide rods.

As a further solution of the present invention: the anti-side guide plate is fixed on the backing plate side of the punch.

As a further solution of the present invention: a spring is installed in the punch backing plate above the die.

Compared with the prior art, the beneficial effects of the present invention are: the automobile uses a shaping and punching die, which simplifies the die structure and reduces the cost of the die. It can be punched and the product can meet the quality requirements, thereby reducing the production cost and shortening the production cycle.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Figures 1 to 3. In the embodiment of the present invention, a plastic punching mold for automobiles includes an upper mold base 1, a punch backing plate 2, a punch fixing plate 3, a die 4, a lower mold base 5, The punch 6, the anti-side guide plate 7 and the punch 8, the upper die base 1, the punch backing plate 2, and the punch fixing plate 3 are fixed together by bolts, and the punch fixing plate 3 is connected to the die by a discharge screw 4. A punch 8 is installed in the die 4, and the punch 8 and the punch fixing plate 3 are fixed together; the lower die base 5 is connected with the punch 6 by screws, and the lower die base 5 is equipped with an anti-side Guide plate 7, anti-side guide plate 7 and lower mold base 5 are fixed together.

Specifically, the punch 6 is provided with a punch groove that matches the punch 8. When the punch 6 is in contact with the die 4, the punch 8 is inserted into the matching punch groove after the punching work is completed, which is convenient for punching. Die 6 and die 4 further perform shaping operations on the workpiece.

Specifically, guide rods are installed on both sides of the lower die base 5, and guide holes are provided on both sides of the upper die base 1. When assembling, the guide rods are inserted into the guide holes, and when the punch 6 and the die 4 are punched, the punch Die 6 slides along guide bar, improves the stability of stamping of punch 6 and die 4.

Specifically, the anti-side guide plate 7 is fixed on the side of the backing plate of the punch 6. When the punch 6 and the die 4 are stamped, the anti-side guide plate 7 relieves and eliminates the sideways friction generated when the punch 6 and the die 4 are in contact with each other. Force, to ensure product quality and mold life.

Specifically, a spring is installed in the punch backing plate 2 above the die 4 to facilitate the return of the die 4 to its original state after punching.

When using, first clamp the mold to the stamping equipment. When working, the contact between the punch 6 and the die 4 starts. The spring above the die 4 and the punch 8 start to work. When the stroke of the die 4 reaches the maximum, the punch 8 punches. After the hole work is completed, the die 4 and the punch backing plate 2 are in a dead state, and the shaping of the product is completed. After the work action is completed, the upper and lower molds are separated, and the die 4 returns to its original state under the action of the spring.

In order to simplify the mold structure and reduce the mold cost on the basis of meeting the production needs. The automobile uses a shaping and punching mold, which adopts a functionally integrated structure of the die 4 and the punch 8, which can be punched while being shaped, and the product can meet the quality requirements, thereby reducing the production cost and shortening the production time. cycle.
