Abstract
Description
Technical Field
[0001] The utility model relates to the field of stamping dies, in particular to an inner and outer slider shaping die. Background Art
[0002] When performing forming processing on certain metal materials, a stamping forming process is often required. The stamping die used in the stamping forming process generally includes an upper die and a lower die. The upper die and the lower die are respectively provided with dies. The upper die moves toward the lower die under the drive of the forming machine. During the movement, the material between the upper and lower dies is squeezed into a shape that matches the die to form a workpiece.
[0003] However, when the traditional stamping die is performing a stamping operation, if the material being stamped is a material with relatively large rebound (such as stainless steel, high-strength steel, etc.), the workpiece will have a large rebound after forming. Therefore, it is necessary to add a step after stamping to shape it to ensure its bending angle; however, the structure of the traditional shaping mechanism is relatively complex and the cost is high; at the same time, some products are also provided with protrusions on the inner side of their bending direction, which will cause the formed product to be unable to be separated from the shaping die. In this way, the operator needs to use tools to assist in the demoulding operation, which greatly reduces the efficiency of the shaping work.
[0004] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention
[0005] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes an inner and outer slider shaping mold which has a simple structure, ingenious design, reasonable layout, can quickly and conveniently complete the shaping of the bending angle, and can smoothly demould the workpiece with a protrusion on the inner side.
[0006] The technical solution of the utility model is: an inner and outer slider shaping mold, including an upper mold and a lower mold that match each other, characterized in that: the upper mold includes an upper mold base 1, an upper pad 2, an upper retaining plate 3 and a pressure plate 4 are arranged in sequence below the upper mold base 1, a spring 5 is arranged between the upper retaining plate 3 and the pressure plate 4, and two symmetrically distributed driving plates 6 are arranged on the bottom end surface of the upper pad 2, a driving inclined surface 7 is arranged at the bottom of the driving plate 6, and the driving plate 6 is connected to the through holes opened on the upper retaining plate 3 and the pressure plate 4.
[0007] The lower die comprises a lower die base 8, a lower retaining plate 9 is arranged above the lower die base 8, two symmetrically distributed sliding inner modules 10 are slidably connected to the lower retaining plate 9, an inner module reset spring 11 is arranged at the bottom of the sliding inner module 10, and the inner module reset spring 11 is located on the inner side of the sliding direction of the sliding inner module 10, an inner driving block 12 is also arranged between the two sliding inner modules 10, the bottom end of the inner driving block 12 is connected to the longitudinal reset spring 17, and at the same time, two symmetrically distributed inner driving block inclined surfaces are arranged at the bottom of the inner driving block 12, and an inner module inclined surface matching the inner driving block inclined surface is arranged at one end of the sliding inner module 10,
[0008] The lower retaining plate 9 is also slidably connected to two symmetrically distributed sliding outer modules 13, and an outer module reset spring 14 is arranged at the bottom of the sliding outer module 13, and the outer module reset spring 14 is located on the outside of the sliding direction of the sliding outer module 13, and an outer module inclined surface matching the driving inclined surface 7 is also arranged on the outside of the sliding outer module 13.
[0009] A recessed hole 15 is formed on the outer end surface of the sliding inner module 10 .
[0010] Compared with the prior art, the utility model has the following advantages:
[0011] This type of inner and outer slider shaping die has a simple structure, ingenious design, and reasonable layout. It is designed to solve various problems existing in the use of traditional stamping dies. It uses two pairs of symmetrically distributed inner and outer modules to extrude the workpiece together, thereby realizing the shaping operation of the bending angle of the workpiece; it has smooth movements, reliable operation, and only needs one extrusion to achieve angle shaping, with high work efficiency; at the same time, this structure in which both inner and outer sliders can slide can also allow the bent workpiece with protrusions on the side wall to be automatically demolded, without the need for an additional demolding process, which can save production costs and time costs. In addition, its manufacturing process is simple and its manufacturing cost is low, so it can be said that it has many advantages and is particularly suitable for promotion and application in this field.

[0013] Figure 2 yes Figure 1 Enlarged view of part A in . DETAILED DESCRIPTION
[0014] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings: Figure 1 , Figure 2As shown, an inner and outer slider shaping mold includes an upper mold and a lower mold that match each other, and is characterized in that: the upper mold includes an upper mold base 1, and an upper pad 2, an upper retaining plate 3 and a pressure plate 4 are arranged in sequence below the upper mold base 1, a spring 5 is arranged between the upper retaining plate 3 and the pressure plate 4, and two symmetrically distributed driving plates 6 are arranged on the bottom end surface of the upper pad 2, and a driving inclined surface 7 is arranged at the bottom of the driving plate 6, and the driving plate 6 is connected to the through holes opened on the upper retaining plate 3 and the pressure plate 4.
[0015] The lower die comprises a lower die base 8, a lower retaining plate 9 is arranged above the lower die base 8, two symmetrically distributed sliding inner modules 10 are slidably connected to the lower retaining plate 9, an inner module reset spring 11 is arranged at the bottom of the sliding inner module 10, and the inner module reset spring 11 is located on the inner side of the sliding direction of the sliding inner module 10, an inner driving block 12 is also arranged between the two sliding inner modules 10, the bottom end of the inner driving block 12 is connected to the longitudinal reset spring 17, and at the same time, two symmetrically distributed inner driving block inclined surfaces are arranged at the bottom of the inner driving block 12, and an inner module inclined surface matching the inner driving block inclined surface is arranged at one end of the sliding inner module 10,
[0016] The lower retaining plate 9 is also slidably connected to two symmetrically distributed sliding outer modules 13, and an outer module reset spring 14 is arranged at the bottom of the sliding outer module 13, and the outer module reset spring 14 is located on the outside of the sliding direction of the sliding outer module 13, and an outer module inclined surface matching the driving inclined surface 7 is also arranged on the outside of the sliding outer module 13.
[0017] A recessed hole 15 is formed on the outer end surface of the sliding inner module 10 .
[0018] The working process of the inner and outer slider shaping die of the embodiment of the utility model is as follows: first, the workpiece 16 punched into a concave shape in the previous process is placed on the two sliding inner modules 10 with the opening facing downward. At this time, the side of the workpiece 16 is located between the sliding inner module 10 and the sliding outer module 13. Then, the press is controlled to work, and the press drives the upper die to move downward as a whole.
[0019] During the downward movement of the upper mold, the two driving plates 6 move toward the direction of the sliding outer module 13, and finally the driving inclined surface 7 at the bottom of the driving plate 6 will contact the outer module inclined surface on the sliding outer module 13. Under the action of the two inclined surfaces, the two sliding outer modules 13 will move toward the center. Since the top of the inner driving block 12 is higher than the top surface of the sliding inner module 10 in the non-pressing shaping state, when the upper mold moves downward, the bottom end surface of the pressing plate 4 will first contact the top of the inner driving block 12 and press the inner driving block 12 downward relative to the two sliding inner modules 10. During the downward movement of the inner driving block 12, the inclined surface of the inner driving block thereon will push the two sliding inner modules 10 to move in two opposite directions at the same time, that is, after the upper mold moves downward as a whole, the sliding inner module 10 and the sliding outer module 13 will clamp the side of the workpiece 16. Under the action of this clamping force, the side of the workpiece 16 will form an angle that matches the sliding inner module 10, thereby realizing the shaping operation of the workpiece 16.
[0020] In the above process, the protrusion on the inner wall of the workpiece 16 will enter the recessed hole 15 on the side wall of the sliding inner module 10;
[0021] After the shaping operation is completed, the upper mold moves upward under the drive of the press. After the external force is lost, the previously compressed springs move, and the longitudinal return spring 17 drives the inner drive block 12 to move upward. At the same time, the inner module return spring 11 drives the two sliding inner modules 10 to move toward each other, and the two sliding inner modules 10 are recovered. The protrusions on the inner wall of the workpiece 16 are separated from the yield countersunk holes 15 on the sliding inner module 10; at the same time, the outer module return spring 14 will also drive the sliding outer module 13 to move toward both sides. At this time, the sliding inner module 10 and the sliding outer module 13 no longer clamp the workpiece 16, and the workpiece 16 can be directly removed from the two sliding inner modules 10.
