[0001] The utility model relates to the technical field of stamping dies, in particular to a side shaping die structure. Background Art

[0002] After the stamping parts are bent and formed in the stamping die, there will be different degrees of springback, which requires necessary shaping process. The shaping generally adopts the side shaping method. The traditional side shaping die structure is as follows: Figure 1 As shown, it includes an upper die pressing block 1', an upper die oblique insert block 2', a lower die block 3' and a side slide block 4'. The workpiece to be shaped is placed on the lower die block 3' and the upper die pressing block 1' presses the workpiece tightly. The side slide block 4' is located on the side of the lower die block 3' and is driven by the upper die oblique insert block 2' to act on the part of the workpiece to be shaped. In addition, the side slide block 4' needs to be accurately displaced by a guide block and reset by a spring member 5'.

[0003] It can be seen that in the above structure, the parts have a large movement range and occupy a large space as a whole, which is not suitable for compact molds. In addition, the side slider 4' and the spring member 5' increase the complexity of the structure, the failure rate is high, and the mold cost is high, which needs further improvement.

[0009] A shaping guide block is arranged on the lower mold plate of the mold and is spaced apart on both sides of the support seat, and a guiding inclined surface is arranged on a surface of the shaping guide block facing the support seat;

[0010] The shaping bracket is arranged on the upper template of the mold and is located on both sides of the pressing block. The bottom of the shaping bracket is rotatably connected with a pendulum block, which is inserted between the support seat and the shaping guide block. One side of the pendulum block slides in cooperation with the guide inclined surface, and the other side of the pendulum block contacts the side of the workpiece.

[0011] Optionally, the spacing between the shaping guide block and the support seat is adjustable to adjust the shaping amount of the workpiece.

[0012] Optionally, the upper end of the pendulum block is connected to the shaping bracket via a pin, and the lower end of the pendulum block is configured as a cone head for easy insertion.

[0013] Optionally, the pendulum block naturally hangs down due to the action of gravity when it escapes from between the support seat and the shaping guide block.

[0014] Optionally, the cone head is a rounded wear-resistant body.

[0015] Optionally, the spacing value between the shaping brackets on both sides is equal to the width value of the support seat plus twice the thickness value of the workpiece.

[0022] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] This preferred embodiment provides a side shaping mold structure, which solves the problems of large movement range, large occupied space, complex structure, high failure rate, etc. of the conventional side slider top pressure shaping structure, and is suitable for compact molds.

[0024] Specifically, Figure 2 As shown, the side shaping mold structure includes a support seat 1, a pressing block 2, a shaping guide block 3 and a shaping bracket 4.

[0025] The support seat 1 is arranged on the lower mold plate of the mold to support the workpiece 5 to be shaped.

[0026] Here, according to the shape of the workpiece 5 and the side shaping requirements, the support seat 1 is in the shape of a round-head pillar, the middle of the workpiece 5 is supported by the support seat 1, and the two sides of the workpiece 5 hang down naturally.

[0027] The pressing block 2 is arranged on the upper mold plate of the mold, and is used to press the workpiece 5 and expose the side of the workpiece 5 .

[0028] The pressing block 2 here is driven by the upper mold plate to move toward the support seat 1 and cooperates with the support seat 1 to press the workpiece 5. The pressure surface of the pressing block 2 is set to a curved surface that matches the shape of the support seat 1.

[0029] The shaping guide block 3 is arranged on the lower mold plate of the mold and is spaced apart on both sides of the support seat 1 . A guiding inclined surface 6 is arranged on a surface of the shaping guide block 3 facing the support seat 1 .

[0030] In particular, the distance between the shaping guide block 3 and the support seat 1 is adjustable to adjust the shaping amount of the workpiece 5 and to adapt to workpieces 5 of different thicknesses.

[0031] Among them, the shaping bracket 4 is arranged on the upper template of the mold and is located on both sides of the pressing block 2. The bottom of the shaping bracket 4 is rotatably connected with a pendulum block 7. The pendulum block 7 is inserted between the support seat 1 and the shaping guide block 3, and one side of the pendulum block 7 slides in cooperation with the guide inclined surface 6, and the other side of the pendulum block 7 contacts the side of the workpiece 5.

[0032] Thus, the shaping bracket 4 is pressed down with the upper mold plate of the mold, driving the pendulum block 7 to be inserted between the shaping guide block 3 and the support seat 1. As the pendulum block 7 is continuously inserted and the angle changes, the side shaping of the workpiece 5 is completed.

[0033] In particular, the upper end of the pendulum block 7 is connected to the shaping bracket 4 via a pin shaft 8, and the lower end of the pendulum block 7 is provided with a cone head 9 for easy insertion, and the cone head 9 is a rounded wear-resistant body.

[0034] Furthermore, when the pendulum block 7 is out of between the support seat 1 and the shaping guide block 3, it naturally hangs down due to the action of gravity, so that when the upper template of the mold returns to the upper position with the shaping bracket 4, the pendulum block 7 automatically returns to the original position without the need for a return member such as a spring.

[0035] Preferably, the spacing value between the shaping brackets 4 on both sides is equal to or slightly larger than the width value of the support seat 1 plus twice the thickness value of the workpiece 5, so that during repeated processing, the pendulum block 7 can be accurately inserted between the shaping guide block 3 and the support seat 1 to maintain normal shaping function.

[0036] It can be seen that the side shaping mold structure replaces the conventional side slider top pressure shaping structure, and uses the lifting pendulum block 7 to be inserted between the shaping guide block 3 and the support seat 1, so that the side shaping of the workpiece 5 can be completed in a small space. During the shaping process, the shaping amount can be adjusted by adjusting the distance between the shaping guide block 3 and the support seat 1. No additional reset parts and guide parts are required. The structure is simple, the space occupied is small, and the adjustment is convenient, which meets the needs of side shaping.

[0037] The above embodiments are only to illustrate the basic principles and characteristics of the utility model. The utility model is not limited by the above embodiments. Without departing from the spirit and scope of the utility model, the utility model has various changes and modifications, which fall within the scope of the utility model to be protected.
