Description

Technical Field

[0001] This utility model belongs to the field of mold forming, and in particular relates to a high-precision, compact, double-sided synchronous side-push high-speed forming mechanism. Background Technology

[0002] Die stamping is a forming method that uses a press and a die to apply external force to sheet metal or other materials, causing plastic deformation or separation to obtain workpieces (stamped parts) of the desired shape and size. Its basic principle is to use a die mounted on a punch press or press to apply pressure to metal or non-metal sheets, causing the material to separate or form, thereby obtaining parts with specific dimensional requirements and acceptable appearance quality. Die stamping has many advantages, such as dimensional accuracy guaranteed by the die, stable and consistent part quality; the ability to obtain thin-walled, lightweight, rigid, high-quality, and complex-shaped parts; high material utilization, being a low-waste or low-chip process; high efficiency, easy operation, and low skill requirements for workers; long die life and low production costs. Therefore, it is widely used in the automotive, aerospace, electronics, and home appliance industries. The dual-side synchronous side-pushing function means that the die can simultaneously push the workpiece from both sides during the forming process, achieving a faster and more uniform forming effect.

[0003] However, in the existing technology, the traditional mold structure, which uses cutters to drive the slider on both sides, occupies a lot of space and is subject to large lateral eccentric forces during molding, making it prone to jamming during high-speed molding. Therefore, a new device needs to be designed. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision, compact, dual-sided synchronous side-push high-speed forming mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-precision, compact, dual-sided synchronous side-push high-speed forming mechanism includes an upper mold base and a lower mold base. The lower mold base is located directly below the upper mold base. An upper pad is installed below the upper mold base, and a fixing plate is installed below the upper pad. A mold core pad is installed on the lower mold base, and a mold core plate is installed on the mold core pad. The mechanism also includes a slider seat installed in the middle of the fixing plate. The slider seat has a limiting cavity in the middle for guiding sliding opening and closing. A forming slider is installed at the bottom of the limiting cavity. The forming slider is a two-part type. A forming groove is provided at the bottom end of the forming slider. A wedge slider is provided above the forming slider. A reset component for releasing elastic push downward pressure is provided at the top of the wedge slider. A lower mold insert is installed in the middle of the mold core plate.

[0007] Furthermore: a stripping pad is provided below the fixed plate, and a stripping plate is installed below the stripping pad. The stripping pad and the fixed plate are elastically connected to ensure that during unloading, the fixed plate pushes the stripping pad with elastic force to support the stripping plate and press down the raw material to complete the unloading.

[0008] Furthermore: the reset assembly includes a force transmission pin disposed above the wedge slider, a reset spring disposed on the force transmission pin, a stop screw disposed on the reset spring, and the stop screw fixed to the top of the slider seat. When the mold is opened, the force transmission pin is pushed down by the elastic force of the reset spring to reset the wedge slider.

[0009] Furthermore, the limiting cavity is divided into three parts, from bottom to top: a relaxation section, a clamping section, and a limiting section. The forming slider slides between the relaxation section and the clamping section to ensure that the forming slider opens and closes smoothly. The limiting section is used to guide and limit the force transmission pin to push the wedge slider to move up and down.

[0010] Furthermore, the fixing plate, the upper pad plate, and the upper mold base are bolted together, and the mold core plate, the mold core pad plate, and the lower mold base are bolted together, which facilitates disassembly and maintenance.

[0011] Furthermore, the top surface of the lower die insert is larger than the bottom surface of the forming slider to ensure sufficient extrusion allowance.

[0012] Furthermore, a tension spring is installed in the middle of the forming slider to increase the stability of the opening and closing of the forming slider.

[0013] Compared with existing technologies, the beneficial effects are:

[0014] 1. By using two forming sliders to open and close with a wedge, the space is compact, the parts are easy to install, the force is even, and it is stable and reliable during high-speed forming. It is especially suitable for products with small pitch, effectively improving the production speed and quality of the products.

[0015] 2. It has a significant effect on situations where the product cannot be pressed during suspended forming. The structure is subjected to force on both sides at the same time, so the product will not be skewed and the quality is stable. Attached Figure Description

[0021] Please see Figures 1-4 The high-precision, compact, dual-sided synchronous side-push high-speed forming mechanism includes an upper mold base 1 and a lower mold base 8. The lower mold base 8 is located directly below the upper mold base 1. An upper pad 2 is installed below the upper mold base 1, and a fixing plate 3 is installed below the upper pad 2. A mold core pad 7 is installed on the lower mold base 8, and a mold core plate 6 is installed on the mold core pad 7. The mechanism also includes a slider seat 9 installed in the middle of the fixing plate 3. A limiting cavity for guiding sliding opening and closing is provided in the middle of the slider seat 9. A forming slider 14 is installed at the bottom of the limiting cavity. The forming slider 14 is a two-part type. A forming groove is provided at the bottom end of the forming slider 14. A wedge slider 13 is provided above the forming slider 14. A reset component for releasing elastic push downward pressure is provided at the top of the wedge slider 13. A lower mold insert 16 is installed in the middle of the mold core plate 6.

[0022] Furthermore: a stripper plate 4 is provided below the fixed plate 3, and a stripper plate 5 is installed below the stripper plate 4. The stripper plate 4 and the fixed plate 3 are elastically connected to ensure that during unloading, the fixed plate 3 pushes the stripper plate 4 with elastic force to support the stripper plate 5 and press down on the raw material to complete the unloading; the reset assembly includes a force transmission pin 12 provided above the wedge slider 13, a reset spring 11 provided on the force transmission pin 12, and a stop screw 10 provided on the reset spring 11. The stop screw 10 is fixed to the top of the slider seat 9. When the mold is opened, the force transmission pin 12 is pushed down by the elastic force of the reset spring 11 to reset the wedge slider 13; the limiting cavity It is divided into three parts, from bottom to top: the relaxation section, the clamping section, and the limiting section. The forming slider 14 slides and opens and closes between the relaxation section and the clamping section to ensure that the forming slider 14 opens and closes smoothly. The limiting section is used to guide the limiting force transmission pin 12 to push the inclined wedge slider 13 to move up and down. The fixing plate 3, the upper pad plate 2 and the upper mold base 1 are bolted together, and the mold core plate 6, the mold core pad plate 7 and the lower mold base 8 are bolted together to facilitate disassembly and maintenance. The top surface of the lower mold insert 16 is larger than the bottom surface of the forming slider 14 to ensure sufficient extrusion allowance. A tension spring 15 is installed in the middle of the forming slider 14 to increase the stability of the opening and closing of the forming slider 14.

[0023] Working principle: The lower die holder 8 is fixed on the extrusion equipment worktable. The raw material is placed on the lower die insert 16 of the die core plate 6. The extrusion equipment pushes the upper pad 2 and the fixed plate 3 downward through the upper die holder 1. First, it pushes the stripper pad 4 and the stripper plate 5 to press and position the raw material. Then, it pushes the slider seat 9 to drive the forming slider 14 to press down and contact the raw material. Since the return spring 11 is in the extended state at this time, it pushes the wedge slider 13 to insert into the middle of the forming slider 14 through the force transmission pin 12, so that the forming slider 14 is in the relaxation section of the limiting cavity and is in the open state. When the slider seat 9 continues to move down to extrude the raw material, the forming slider 14 slides along the relaxation section of the limiting cavity to the clamping section, compresses the tension spring 15, and enters the closed state, forming... When the top of slider 14 closes, it pushes the wedge slider 13 to rise, compressing the return spring 11 through the force transmission pin 12. At the same time, the bottom of forming slider 14 closes, and the raw material is squeezed from both sides through the forming groove at the bottom. After completion, the extrusion equipment drives the upper pad 2 and the fixed plate 3 to rise through the upper mold base 1. The slider seat 9 is driven to rise, and the return spring 11 releases its elastic force and extends. Through the force transmission pin 12, it pushes the wedge slider 13 to move down and insert into the middle of the forming slider 14. At the same time, the forming slider 14 slides into the relaxation section of the limiting cavity. The elastic force of the tension spring 15 pushes the forming slider 14 to open. Then the upper mold base 1 continues to rise, and the stripper pad 4 pushes the stripper plate 5 to remove the raw material on the slider seat 9 under the action of the elastic force.
