Background Art

Moulds are various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. In short, moulds are tools used to make shaped objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the material being formed. It is known as the "mother of industry".

During the stamping process of the existing mold, the workpiece is easily embedded in the lower mold due to the stamping of the upper mold. Once the workpiece is embedded in the lower mold, the user needs to use tools to lift the workpiece out, which is cumbersome and inconvenient.

Therefore, it is necessary to provide a mold with a positioning mechanism to solve the above technical problems.

DETAILED DESCRIPTION

The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

Please refer to Figures 1 to 3, wherein Figure 1 is a schematic structural diagram of a preferred embodiment of a mold with a positioning mechanism provided by the utility model; Figure 2 is a schematic structural diagram of the positioning frame and the lower mold installation structure shown in Figure 1; and Figure 3 is a schematic structural diagram of the ejector plate installation structure shown in Figure 1. A mold with a positioning mechanism comprises a positioning plate 1, wherein both sides of the upper surface of the positioning plate 1 are provided with slide grooves 2, an adjusting screw 3 is rotatably installed inside the upper surface of the positioning plate 1 through a bearing, a positioning frame 4 is slidably installed on the upper surface of the positioning plate 1 through two slide grooves 2, the positioning frame 4 and the adjusting screw 3 are threadedly connected, both sides of the inner wall of the positioning frame 4 are provided with limiting grooves 5, a base 6 is slidably installed inside the positioning frame 4 through two limiting grooves 5, cylinders 7 are fixed inside both sides of the positioning frame 4 and on both sides of the base 6, and a lower mold 8 is fixed to the upper surface of the base 6 by bolts;

The user fixes the lower mold 8 and the base 6 with bolts, and then the user starts the two cylinders 7. The output shafts of the two cylinders 7 are fixedly connected to the outer walls of the two sides of the base 6 respectively. Therefore, by starting the two cylinders 7, the position of the base 6 inside the positioning frame 4 can be adjusted and fine-tuned so that the lower mold 8 and the upper mold 15 can be completely embedded. After the installation of the lower mold 8 is completed, the user places the workpiece on the top of the lower mold 8. Then, the user rotates the adjusting screw 3, and the positioning frame 4 can be driven to move forward to the bottom of the upper mold 15 through the threaded connection between the adjusting screw 3 and the positioning frame 4. Moving the positioning frame 4 by adjusting the screw 3 can facilitate the user to install and remove the lower mold 8 and also facilitate loading and unloading of the workpiece.

Ejector plates 9 are installed on both sides of the lower mold 8. Spherical air bags 10 are equidistantly fixed at the four corners of the bottom of the ejector plate 9 and inside the lower mold 8. Positioning rods 11 are equidistantly fixed on both sides of the upper surface of the positioning plate 1.

After the stamping is completed, the workpiece is positioned inside the lower mold 8 and can be ejected through the ejector plate 9. Because the bottom end of the ejector plate 9 is provided with a spherical airbag 10, the spherical airbag 10 is squeezed during stamping and the ejector plate 9 is at the same level as the inside of the lower mold 8. When the upper mold 15 leaves, the workpiece can be ejected through the spherical airbag 10 so that the user can take the material.

A top plate 12 is fixed to the upper surface of the four positioning rods 11, and a sliding plate 14 is slidably installed outside the four positioning rods 11 and below the top plate 12;

When the upper mold 15 is pressed downward by the hydraulic cylinder 13 , the sliding direction of the upper mold 15 can be limited by the cooperation between the sliding plate 14 and the four positioning rods 11 .

Hydraulic cylinders 13 are fixed on both sides of the upper surface of the top plate 12. The output shafts of the two hydraulic cylinders 13 penetrate the top plate 12 and are fixedly connected to both sides of the upper surface of the sliding plate 14. The lower surface of the sliding plate 14 is bolted with an upper mold 15.

The hydraulic cylinder 13 is activated to move the upper die 15 downward to engage with the lower die 8 for stamping.

The working principle of a mold with a positioning mechanism provided by the utility model is as follows:

The user fixes the lower mold 8 to the base 6 with bolts, and then the user starts the two cylinders 7. The output shafts of the two cylinders 7 are fixedly connected to the outer walls of the two sides of the base 6 respectively. Therefore, by starting the two cylinders 7, the position of the base 6 inside the positioning frame 4 can be adjusted and fine-tuned so that the lower mold 8 and the upper mold 15 can be completely fitted. After the installation of the lower mold 8 is completed, the user places the workpiece on the top of the lower mold 8. Then, the user rotates the adjusting screw 3, which can be driven by the threaded connection between the adjusting screw 3 and the positioning frame 4. The positioning frame 4 can be translated forward until it reaches the bottom of the upper mold 15, and then the user starts the hydraulic cylinder 13, which causes the upper mold 15 to move downward and engage with the lower mold 8 for stamping. After the stamping is completed, the workpiece is positioned inside the lower mold 8 and can be ejected through the ejection plate 9. Because a spherical airbag 10 is provided at the bottom end of the ejection plate 9, the spherical airbag 10 is squeezed during stamping, and the ejection plate 9 and the inside of the lower mold 8 are at the same horizontal plane. When the upper mold 15 leaves, the workpiece can be ejected through the spherical airbag 10 so that the user can take the material.

Compared with the related art, the mold with a positioning mechanism provided by the utility model has the following advantages:

Beneficial effects:

The user fixes the lower mold 8 and the base 6 with bolts, and then the user starts the two cylinders 7. The output shafts of the two cylinders 7 are fixedly connected to the outer walls of the two sides of the base 6 respectively. Therefore, by starting the two cylinders 7, the position of the base 6 inside the positioning frame 4 can be adjusted and fine-tuned so that the lower mold 8 and the upper mold 15 can be completely fitted. After the installation of the lower mold 8 is completed, the user places the workpiece on the top of the lower mold 8. Then, the user rotates the adjusting screw 3, and the positioning frame 4 can be driven to move forward to the bottom of the upper mold 15 through the threaded connection between the adjusting screw 3 and the positioning frame 4. Moving the positioning frame 4 by adjusting the screw 3 can facilitate the user to install and disassemble the lower mold 8 and also facilitate loading and unloading of the workpiece. After the stamping is completed, the workpiece is located inside the lower mold 8 and can be ejected by the ejector plate 9. Because the bottom end of the ejector plate 9 is provided with a spherical airbag 10, when the spherical airbag 10 is squeezed during stamping, the ejector plate 9 and the inside of the lower mold 8 are at the same horizontal plane. When the upper mold 15 leaves, the workpiece can be ejected by the spherical airbag 10 so that the user can take the material.
