Description

Technical Field

[0001] The utility model relates to the field of automobile molds, in particular to a double-process mold for drain groove trimming, side punching and trimming, and side trimming and punching. Background Art

[0002] The engine compartment drain is usually located at the rear of the engine compartment, near the lower edge of the windshield and the air-conditioning inlet, and is an important part of the car body. This location is designed to effectively collect rainwater flowing in from the windshield. On rainy days or when washing the car, the water is drained out of the car through the drain to prevent moisture from entering the engine compartment, thereby protecting the engine and related electrical components from damage.

[0003] The vehicle body drain groove is usually made by punching out the plate through a stamping die. However, since the drain groove needs to adapt to the complex structure of the engine compartment at the front of the vehicle body and ensure a stable connection with the vehicle body, the overall structure of the drain groove is relatively complex and requires multiple processes such as trimming, punching, and side punching to be punched out into a finished product. At present, the drain groove is usually gradually processed into shape by combining multiple sets of molds. There are many processes and frequent turnover of workpieces, which is not conducive to ensuring quality and improving efficiency, and needs to be improved. Utility Model Content

[0020] Example 1, see the attached specification Figure 1-5A double-process mold for trimming and punching a drainage trough, comprising an upper mold base 02 and a lower mold base 01, wherein a lower mold core A 11 and a lower mold core B 12 are arranged side by side on the surface of the lower mold base 01, and an oblique wedge seat A 113 and an oblique wedge seat B 114 are respectively arranged on both sides of one end of the lower mold core A 11, and a notch A 111 is arranged on the lower mold core corresponding to the oblique wedge seat A 113, and a notch A 111 is arranged on the lower mold core corresponding to the oblique wedge seat B 114 The surface of the lower die core B 112 is provided with a punch hole 13, and the edges of the two lower die cores are provided with lower trimming cutters 14; the upper die core A 21 and the upper die core B 22 are slidably installed in the die cavity of the upper die seat 02, and a plurality of limit plates 26 are evenly arranged at the port of the die cavity, and the sliding stroke of the upper die core A 21 and the upper die core B 22 is limited by the limit plates 26. The lower die core A 11 and the upper die core A 21 are responsible for trimming and side punching of the workpiece. The lower die core B 12 and the upper die core B 22 are responsible for the trimming, side trimming and punching processes of the workpiece. The upper die core A 21 is provided with an oblique wedge A 211 and an oblique wedge B 212 on both sides of one end of the upper die core A 21. The upper die core A 21 is provided with a side hole A 211 and a side hole B 212. The size of the notch matches the size of the above-mentioned notch. The side punch A 213 of the oblique wedge A 211 corresponds to the side hole A 211, and the side punch B 214 of the oblique wedge B 212 corresponds to the side hole B Corresponding to 212, after the punch 23 enters the side punching hole, it can enter the notch on the lower die core to realize the side punching of the workpiece. The surface of the upper die core B 22 is provided with a punch 23 corresponding to the punch hole 13, and the size of the punch 23 matches the size of the punch hole 13. The edges of the two upper die cores are provided with upper trimming cutters 24. The positions of the upper trimming cutters 24 and the lower trimming cutters 14 correspond. When the mold is closed, the upper and lower cutters fit together and slide for trimming and punching.

[0021] L-shaped bent positioning rods 16 are provided on the ends and sides of the lower mold base 01 of the lower mold core A 11 and the lower mold core B 12. The inner side surface of the positioning rod 16 is provided with a guide slope. The limiting rods can quickly place the workpiece onto the mold core through the guide slope, and the limiting rods are arranged around the mold core. After the workpiece is placed on the mold core, these limiting rods can play a limiting role to ensure that the workpiece is located in the accurate stamping position.

[0022] A waste cavity 17 is provided in the lower die base 01, and waste chutes 31 extending into the waste cavity 17 are provided on both sides of the lower die base 01. A large amount of scraps will be generated at various positions of the mold core during the process of mold closing and blanking. These scraps can fall into the waste cavity 17 nearby and then be discharged from the mold through the waste chute 31, thereby avoiding the accumulation of scraps and ensuring efficient and continuous punching of the workpiece.

[0023] The surfaces of the four corners of the lower mold base 01 are provided with buffers 18, and limit blocks 181 are arranged side by side on one side of the buffer 18. The buffer 18 is provided to buffer the impact force between the mold bases to ensure the stability of the mold clamping, and the limit blocks 181 are used to limit the maximum clamping stroke of the mold.

[0024] Support square tubes 19 are hinged on both sides of the end surface of the lower mold base 01. After rotating, the support square tubes 19 can be supported on the surface of the lower mold base 01. When the mold is in an idle state, it is supported between the two mold bases by the support square tubes 19 to prevent the pressure of the mold base itself from damaging the surface of the mold core.

[0025] The bevel wedge seat A 113 and the bevel wedge seat B 114 are both connected to the lower die seat 01 through the support platform 20. The bevel wedge seat A 113 and the bevel wedge seat B 114 are both higher than the upper surface of the lower die seat 01. This design enables the bevel wedge seat to provide sliding top pressure for the bevel wedge from below, driving the side punch 23 to slide inward to achieve side punching.

[0026] When the mold is punching the drainage groove, the workpiece is first placed on the lower mold core A 11. The limiting rods around the mold core can limit the workpiece so that the workpiece is located in the accurate stamping position. The upper mold base 02 is driven to move downward, and the upper mold core A 21 presses the workpiece against the lower mold core A 11 to achieve trimming and side punching. The principle of side punching has been explained above. Then the upper mold base 02 is driven to move upward, and the workpiece is taken out and placed on the lower mold core B 12. The upper mold base 02 is driven downward again, and the upper mold core B 22 presses the workpiece against the lower mold core B 12 to achieve trimming, side trimming and punching. A set of molds can be closed twice to complete multiple processes of punching the drainage groove. There is no need to adopt the traditional processing mode of combined punching of multiple sets of molds, which effectively reduces the number of molds. The workpiece does not need to be frequently turned over during the processing, which is beneficial to improving the processing quality and efficiency of the workpiece.

[0027] Example 2, see the attached specification Figure 1-2 4. In this embodiment, on the basis of the first embodiment, centering convex seats 15 are provided at the four corners of the lower mold core A 11 and the lower mold core B 12, and centering concave seats 25 are provided at the four corners of the upper mold core A 21 and the upper mold core B 22. The centering convex seats 15 and the centering concave seats 25 match in size and face each other vertically. When the mold is closed for punching, the centering concave seats 25 around the mold core are matched and inserted into the centering convex seats 15, providing mold closing guide positioning around the mold core to avoid relative displacement between the mold cores due to pressure. To ensure the accuracy of blanking, square guide grooves 41 are provided at both ends of the lower die base 01, guide columns 42 are provided at the bottom of the guide grooves, square slides 43 are provided at both ends of the upper die base 02, guide holes 44 corresponding to the guide columns 42 are provided in the square slides 43, and the square guide grooves 41 and the square slides 43 form a mold closing guide mechanism at both ends of the mold to ensure the accuracy of the position between the mold bases when closing the mold. Combined with the guide positioning between the above-mentioned mold cores, the mold closing and blanking quality of the workpiece can be effectively guaranteed.
