Description

Technical Field

[0001] The utility model relates to the technical field of radar and antenna processing, in particular to a forming mold for skin parts. Background Art

[0002] During the production process of skin parts, sheet metal parts need to be stretched and stamped. Because some skin parts have large curvatures, templates with the same curvature can fully squeeze the parts. However, this inevitably results in excessive contact area between the template surface and the curved surface of the part, causing scratches between the curved surface of the part and the template surface during the removal process, affecting the quality of the part. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcoming in the prior art that the template is easy to be scratched against the surface of the part when leaving the template, and to propose a forming mold for skin parts.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A forming mold for skin parts is designed, including a mold base, the bottom inner side of the mold base is connected to a bottom mold plate by a screw, first telescopic parts are fixedly installed on both sides of the mold base, and side mold plates are fixedly installed on the ends of the first telescopic parts, second telescopic parts are also fixedly installed on both sides of the mold base, and lifting plates are fixedly installed on the ends of the second telescopic parts, and the lower surface of the lifting plate is connected to the top mold plate by a screw.

[0006] Preferably, a flange is fixedly mounted on the surface of the side formwork close to the bottom formwork, and the flange is located at one side of the lower end of the side formwork.

[0007] Preferably, an edge is fixedly installed on the upper end surface of the side template, and strip grooves are opened on both sides of the lower end of the top template. The edge fits inside the strip grooves, and the edge and the strip grooves are both located on the side close to the first telescopic member.

[0008] Preferably, a slide groove is provided on the inner bottom surface of the mold base, and a slider is fixedly installed on the lower end of the side template, and the slider is slidably arranged in the slide groove.

[0009] Preferably, the first telescopic member is arranged horizontally, and the second telescopic member is arranged vertically.

[0010] The utility model proposes a forming mold for skin parts, which has the beneficial effect that: during use, the forming mold for skin parts can continue to clamp and restrict the stamped parts through the bottom template, side template and top template to prevent the parts from rebounding. The side template and the top template are separated to prevent the template from scratching the part surface when detaching, and the formed parts can be taken out without damaging the parts.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Example 1: Reference Figure 1-4 A forming mold for skin parts includes a mold base 1. The inner bottom of the mold base 1 is connected to a bottom template 2 via a screw 13. First telescopic members 3 are fixedly installed on both sides of the mold base 1. The first telescopic members 3 are arranged horizontally. Side templates 4 are fixedly installed at the ends of the first telescopic members 3. The side templates 4 are located on both sides of the bottom template 2. Activating the first telescopic members 3 can drive the side templates 4 to move horizontally. A chute 7 is provided on the inner bottom surface of the mold base 1. A slider 6 is fixedly installed at the lower end of the side template 4. The slider 6 is slidably arranged in the chute 7. Movement of the side template 4 can drive the slider 6 to slide in the chute 7. The length direction of the chute 7 is parallel to the length direction of the first telescopic member 3, which can provide stable support for the side template 4.

[0018] The side formwork 4 is fixedly mounted with a flange 5 on the surface close to the bottom formwork 2. The flange 5 is located on one side of the lower end of the side formwork 4 and protrudes from the side of the side formwork 4. Figure 1 As shown, when the flange 5 is fitted with the side surface of the bottom template 2, a gap for accommodating parts is left between the side template 4 and the bottom template 2, and the two ends of the parts can be clamped and positioned by the side template 4 and the bottom template 2.

[0019] A second telescopic member 9 is also fixedly installed on both sides of the mold base 1. The second telescopic member 9 is set vertically, and a lifting plate 10 is fixedly installed on the end of the second telescopic member 9. Starting the second telescopic member 9 can drive the lifting plate 10 to move up and down. The lower surface of the lifting plate 10 is connected to the top template 11 through a screw 13. The up and down movement of the lifting plate 10 can drive the top template 11 to move up and down. A groove body is provided on the lower surface of the top template 11 to match the upper end of the bottom template 2. After the top template 11 and the bottom template 2 cooperate with each other, a cavity is left. The cavity is connected to the gap between the bottom template 2 and the side template 4, which can just accommodate the entire part. In addition, a heating element is provided inside the surface where the template contacts the part. The heating element is a prior art and the part can be heated by the heating element.

[0020] The upper end surface of the side template 4 is fixedly installed with an edge 8, which protrudes from the upper surface of the side template 4. Strip grooves 12 are provided on both sides of the lower end of the top template 11. The edge 8 fits inside the strip groove 12. The edge 8 and the strip groove 12 are both located on the side close to the first telescopic member 3. When the edge 8 and the strip groove 12 fit tightly, the upper end of the side template 4 and the lower end of the top template 11 are kept firmly connected.

[0021] Working principle: When the forming mold for skin parts is used, the skin parts are placed on the bottom template 2, and the second telescopic member 9 is started to drive the lifting plate 10 to move downward. The downward movement of the lifting plate 10 can drive the top template 11 to move downward. The downward movement of the top template 11 can stamp the skin parts to deform the skin parts. Then, the first telescopic member 3 is started to drive the side templates 4 to move closer to each other to squeeze the two ends of the skin parts that are raised. At the same time, the parts are heated by the heating member so that the skin parts are stamped and formed. The top template 11 can also continue to clamp and limit the parts after stamping to prevent the parts from rebounding. After the parts are formed, the first telescopic member 3 can be started first to drive the side template 5 away from the parts. Since the side template 5 is located on the smooth and non-curved side of the part, the side template 5 will not scratch the surface of the part when it leaves. Then the second telescopic member 9 is started to drive the top template 11 away from the part. Since the top template 11 only contacts the curved surface of the part, the top template 11 will not scratch the surface of the part when it leaves, and the formed parts can be taken out without damaging the parts.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
