Description

Technical Field

[0001] This utility model relates to the field of mold-related technology, and in particular to a stamping die. Background Technology

[0002] Existing profile frames, such as those included in the instruction manual. Figure 1 and 2 As shown, the profile frame 100 is generally composed of four profiles 101 spliced ​​together. The 45° bevels at both ends of each profile are generally cut by a sawing machine. Cutting the 45° bevels at both ends of the profile by a sawing machine is inefficient and affects the production efficiency of the profile frame. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a stamping die to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a stamping die is designed, comprising:

[0006] The lower die includes a lower die base, a punching head, and a punching seat. The punching head slides longitudinally with a guide seat fixed to the lower die base. The included angle between the two inclined surfaces at the left and right ends of the punching head is 45°, and the included angle between the inclined surfaces and the top surface of the lower die base is also 45°. The rear end of the punching head is provided with a first driving inclined surface and a reset driving assembly connected to drive it to reset. The punching seat is located in front of the guide seat and forms a feeding channel between them for the profile to pass through laterally. The punching seat is provided with a V-shaped material opening for the punching head to enter and punch the profile. The included angle between the two inclined surfaces in the V-shaped material opening is 45°.

[0007] An upper die is disposed above the lower die. The upper die includes an upper template and an upper die assembly disposed above the upper template. The bottom of the upper die assembly is connected to a stripper block located above the feeding channel. The stripper block is provided with a channel opening for the punching head to pass through. A first spring is provided between the upper die assemblies and connected to both. A driving block is fixedly connected to the bottom of the upper die assembly. The lower end of the driving block is located in a through hole on the upper template. When the upper die moves down, the stripper block moves down to press and fix the profile entering the feeding channel. The second driving inclined surface at the lower end of the driving block slides and engages with the first driving inclined surface to drive the punching head forward into the V-shaped material opening.

[0008] Using the above technical solution, when a 45° bevel needs to be cut at the end of the profile, the profile is fed from the left side of the lower die to the right into the feeding channel. The upper die moves down to cooperate with the lower die, and the lower die moves down in conjunction with the stripper block. The stripper block moves down to abut the rear side plate of the lower end of the profile against the lower die base and fixes it. As the upper die moves down, the drive block continues to move down in conjunction with the drive block, causing the second drive bevel at its lower end to slide and cooperate with the first drive bevel, thereby driving the punching head to move forward. The punching head moves forward to punch the profile and pushes the punched waste into the V-shaped material outlet for discharge. When the punching is finished, the upper die moves up to reset, and the reset drive assembly drives the punching head to move backward to reset. This cycle is repeated to achieve continuous punching processing. Compared with using a sawing machine to cut out the 45° bevel at the end of the profile, this stamping die can punch out two 45° bevels at once. The punching speed is fast and the efficiency is high, which can greatly improve the production efficiency of the profile frame.

[0009] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0010] In some embodiments, a plurality of guide rods are fixedly connected to the upper module, and the guide rods slide in engagement with guide holes on the lower mold.

[0011] In some embodiments, the guide seat is provided with a V-shaped groove, and the punching head slides in conjunction with the V-shaped groove.

[0012] In some embodiments, the reset drive assembly includes a fixed block, a slide rod, and a second spring. The fixed block is located on the rear side of the guide seat and is fixedly connected to the lower die seat. The slide rod is longitudinally slidably engaged with a through hole on the fixed block, and the front end of the slide rod is fixedly connected to the punching head. The second spring is sleeved on the slide rod, with its front end abutting against the fixed block and its rear end abutting against a stop fixedly connected to the rear end of the slide rod.

[0013] In some embodiments, a pad that is fixedly connected to the lower mold base is provided on the outer side of the guide seat.

[0014] In some embodiments, the lower mold base is provided with clearance holes that correspond vertically to the drive block to avoid the drive block.

[0015] In some embodiments, the upper end of the V-shaped groove is provided with two first limiting portions located above both ends of the punching head. The first limiting portions are used to limit the upward movement of the punching head, ensuring stable longitudinal movement of the punching head.

[0016] In some embodiments, the upper end of the V-shaped feed port is provided with two second limiting parts.

[0017] In some embodiments, the front side of the punching head is provided with a first contact surface, a second contact surface, and a third contact surface located between the first and second contact surfaces and inclined in shape. When the profile is punched, the three contact surfaces simultaneously contact the three surfaces on the profile for punching, ensuring that the punched surface of the profile is flat and improving the punching effect.

The second spring 43 is sleeved on the slide rod 42, and its front end abuts against the fixed block 41. Its rear end abuts against the stop 421 fixedly connected to the rear end of the slide rod 42. The stop 421 is a nut fixedly connected to the slide rod 42, or a ring welded to the slide rod 42, or a circular stop head integral with the slide rod 42.

[0035] The punching seat 13 is located on the front side of the guide seat 3 and is fixedly connected to the lower die seat 11. A feeding channel a is formed between the punching seat 13 and the guide seat 3 for the profile 101 to pass through laterally. The punching seat 13 is provided with a V-shaped material outlet 131 for the punching head 12 to enter and punch the profile 101. The included angle between the two inclined surfaces inside the V-shaped material outlet 131 is 45°. The included angle between the inclined surfaces inside the V-shaped material outlet 131 and the top surface of the lower die seat 11 is 45°.

[0036] The guide seat 3 consists of two seat bodies, one on the left and one on the right. A pad 5 is provided on the outside of the guide seat 3 and is fixedly connected to the lower mold seat 11.

[0037] The upper mold 2 includes an upper template 21 and an upper mold assembly 22 located above the upper template 21. The upper mold assembly 22 is composed of a template or an upper mold base plate and a pad fixed to the bottom of the upper mold base plate. The bottom of the upper mold assembly 22 is connected to a stripper block 6 located above the feed channel a. The stripper block 6 is provided with a channel opening 61 for the punching head 12 to pass through. The channel opening 61 is a right-angled triangle. Two, three, or four first springs 7 are provided between the upper mold assembly 22 and the upper mold assembly 22 and connected to both. A drive block 8 is fixed to the bottom of the upper mold assembly 22. The drive block 8 is located above the rear end of the punching head 12.
