Description

A flanging shaping mold

technical field

The utility model relates to a shaping die, in particular to a flanging shaping die, which belongs to the field of stamping dies for automobile sheet parts.

Background technique

With the improvement of people's living standards, people's demand for cars is growing rapidly, and people's requirements for cars are getting higher and higher. People's selection criteria for cars are no longer economical, practical, and comfortable. People pay more attention to beautiful appearance and good safety performance. In order to meet market demand. The automotive industry has higher and higher requirements for mold technology.

In the prior art, the joints between the side wall 50 and the front windshield and the top cover are basically rolled over into place through two processes. A kind of flanging shaping mold in the prior art as shown in Figure 1. In the side turning operation process, at first the inclined wedge 30 is used to turn over one section of the side wall, and then the inclined wedge 31 is used to turn over the other section of the side wall. In this way, there is a problem of "knife crossing" in the two rollovers, and traces will appear at the "knife crossing". Such traces cannot be eliminated in the subsequent processing, which seriously affects the appearance quality of the product and cannot meet customer requirements. Moreover, during the two flanging processes, the cost of the flanging device is high, the debugging period is long, and the efficiency of the product production process is also low.

As shown in FIG. 2 , there is also a flanging shaping mold in the prior art, which adopts the method of one-time molding of the side wall 50 . This flanging shaping mold adopts an integral type inclined wedge 32, and this integral type inclined wedge 32 has a certain angle. However, the product formed by this flanging shaping mold deviates from the actual numerical control model, resulting in poor product quality.

In view of this, it is necessary to improve the existing flanging plastic mold to solve the above problems.

Utility model content

The purpose of the utility model is to provide a flanging plastic mold, which can eliminate the "knife crossing" traces in the process of multiple flanging in the prior art, improve the appearance quality of the product, reduce the cost of the flanging device, and shorten the debugging Cycle, improve production efficiency.

In order to achieve the purpose of the above utility model, the utility model provides a flanging plastic mold (100), which at least includes

Upper slotting knife (1), side pressing plate (4), side flanging knife (9), several oblique wedges (40), and

a first stroke back plate (2) fixed on the upper blade (1); and a base (14),

The flanging shaping mold (100) also includes a plurality of push-type positioning blocks (11) arranged on the base (14), and a second stroke back plate (3) and sliding protrusions (10) are fixedly connected to both sides thereof.

As a further improvement of the utility model, the upper inserting knife (1) moves vertically downward, and drives the second stroke backplane (3) through the first stroke backplane (2) to drive the push positioning block (11) and the sliding lug (10), and move towards the side pressing plate (4) and the side turning edge knife (9) along the base (14).

As a further improvement of the present utility model, the flanging shaping mold (100) further includes several limiting blocks (12), which are fixed in the base (14).

Compared with the prior art, the beneficial effect of the utility model is: by adding a push-type positioning block in the flanging plastic mold, the trace of "knife crossing" can be effectively eliminated, the appearance quality of the product can be improved, and the cost of the flanging plastic mold can be reduced , shorten the debugging cycle and improve production efficiency.

Detailed ways

The utility model will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the utility model, and those of ordinary skill in the art can perform functions, methods, or structures based on these implementations. The above equivalent transformation or replacement all belong to the protection scope of the present utility model.

Referring to a specific embodiment of an integral flanging shaping mold 100 of the present invention shown in FIG. 3 . In this embodiment, a flanging shaping mold 100 at least includes: an upper inserting knife 1, a side pressing plate 4, a side flanging edge knife 9, several oblique wedges 40, and the upper inserting knife 1 a first travel backboard 2; and a base 14, the flange shaping mold 100 also includes a number of push positioning blocks 11 arranged on the base (14), and a second travel backboard 3 and a second travel backboard 3 are fixedly connected to both sides thereof. Slide bump 10.

The upper slotting knife 1 moves vertically downward, drives the second stroke backplane 3 through the first stroke backplane 2, and is used to drive the push-type positioning block 11 and the sliding protrusion 10, and presses the material along the base 14 and the side Plate 4 and side flanging knife 9 move toward each other. The flanging shaping mold 100 also includes a number of limiting blocks 12 fixed in the base 14 .

Refer to FIG. 4 and FIG. 5 in conjunction. When the flanging and shaping die 100 starts to work, the flanging and shaping die 100 starts to descend under the action of a press (not shown). The mold outer guide (not shown) begins to guide. At this time, the first stroke back plate 2 fixed on the upper blade 1 and the upper blade 1 fixed on the upper mold base (not shown) follow the upper mold base and move downward together in the vertical direction. When the upper mold base descends to 142mm apart from the mold closure, the travel back plate 2 starts to contact the travel back plate 3 installed on the push positioning block 11 . Under the action of the first stroke backboard 2 and the second stroke backboard 3, the push type positioning block 11 is pushed to move to the left.

When the push-type positioning block 11 moves to the left and reaches the working position, it stops moving. The upper mold base continues to descend, and the space between the first stroke backboard 2 and the second stroke backboard 3 starts to move downward in the vertical direction, so as to ensure that the position of the push type positioning block 11 is fixed.

When the mold goes down to 124mm away from the mold closing, the wedge drive block 6 installed on the upper mold base starts to contact the wedge slide block 7 through the wedge guide plate 5 installed on the wedge drive block 6 and drives the wedge slide block 7. Go down together in the vertical direction. When the wedge slide block 7 is in motion, the side clamping plate 4 installed on the slide block 7 will first contact with the product 13 through the nitrogen gas spring 8 installed on the slide block 7 . Then the wedge slide block 7 moves to the left again. The side hold-down plate 4 starts to compress the product 13, and the side flanging knife 9 installed on the wedge slide 7 just begins to contact the product 13, and the product 13 is started to be processed by side flanging.

Along with wedge slide block 7 continues to move, side flanging knife 9 contacts with the slide block punch 10 that is installed on the push-type locating block 11 fully, and finally flanging is finished, and operation finishes.

In this embodiment, several oblique wedges 40 are flanged at the same stamping angle at different running angles, and the "knife-crossing" places between the flanging knives 9 of the oblique wedges 40 are obliquely butted. When the wedges 40 move to the final position of the product 13 according to their respective motion directions, the gap reaches 0 mm.
