Description

TECHNICAL FIELD

[0001] The application relates to a refrigerator stamping die technical field, in particular to a refrigerator injection molding part production stamping die. BACKGROUND

[0002] Stamping is to exert external force on plates, strips, tubes and profiles by a press and a die, and in order to meet the green economy, the raw material of the injection molding part is recycled from waste plastic, and then the stamping machine is used for further pressing, so that the forming processing method of the workpiece (stamping part) with the required shape and size is obtained; with the continuous development of modern social science and technology and the improvement of economic level, the refrigerator is more and more widely used in life. The refrigerator injection molding part is generally made by using a stamping die in the production process.

[0003] In the production of the press base plate, in order to improve the stamping efficiency, the whole machine stamping is designed, and the basic stamping process is completed by repeated stamping of a single die. However, when stamping, the plate needs to be stamped, cut and punched during bending, and since the stamping is from top to bottom, the edge of the punched hole will be bent downward after stamping, and the bending edge will cause the plate to jump when the plate continues to move horizontally, finally resulting in changes in the stamping position of the plate. In view of the above problems, the following scheme is proposed. SUMMARY

[0004] To solve the above technical problems, the application provides a refrigerator injection molding part production stamping die, which comprises a base, a telescopic rod fixedly connected to the top of the base, a top plate fixedly connected to the end of the telescopic rod away from the base, and further comprises:

[0005] A positioning mechanism fixedly connected to the top of the base for receiving the metal plate;

[0006] A sliding mechanism fixedly connected to the inner wall of the positioning mechanism for reducing the contact area between the concave edge of the plate and the positioning mechanism;

[0007] A pressing mechanism fixedly connected to the bottom of the top plate for cooperating with the positioning mechanism and extruding and punching the plate.

[0008] Preferably, the positioning mechanism comprises:

[0009] A fixing assembly fixedly connected to the top of the base;

[0010] An auxiliary assembly fixedly connected to the top of the fixing assembly;

[0011] In use, the plate passes through the gap between the fixing assembly and the auxiliary assembly, so that the plate can only move horizontally.

[0012] Preferably, the sliding mechanism comprises:

[0013] The contact assembly is fixedly connected to the inner wall of the auxiliary assembly.

[0014] The limiting assembly is rotatably connected to the inner wall of the contact assembly.

[0015] After the plate is punched, the remaining excess material will accumulate inside the contact assembly, and the excess material will contact the inner wall of the contact assembly and be limited by the limiting assembly, and finally the excess material will be discharged.

[0016] Preferably, the pressing mechanism comprises:

[0017] The plastic assembly is fixedly connected to the bottom of the top plate.

[0018] The pressure assembly is fixedly connected to the bottom of the plastic assembly.

[0019] Before use, the top plate and the base are fixedly installed in the punch, and the punch drives the base and the top plate to contact each other.

[0020] Preferably, the fixing assembly comprises a sliding rod fixedly connected to the top of the base, and a sliding plate slidably connected to the outer wall of the sliding rod.

[0021] Under normal circumstances, the spring is in an extended state, and drives the sliding plate to be in the highest position of the sliding rod. When the top pressure assembly extrudes the sliding plate, the sliding plate slides downward along the inner wall of the sliding rod, and forces the bottom of the sliding plate to contact the top of the base.

[0022] Preferably, the auxiliary assembly comprises a positioning frame fixedly connected to the top of the sliding plate, a through hole one is formed in the top of the sliding plate, a plastic groove is formed in the top of the sliding plate, and a chamfer is formed in the edge of the outer wall of the through hole one.

[0023] During use, the injection molded part plate will pass through the gap between the positioning frame and the sliding plate, and under the impact of the pressure assembly, the plate will complete the punching and punching process through the through hole one.

[0024] Preferably, the contact assembly comprises a fixed track fixedly connected to the inner wall of the through hole one, a ring-shaped plate slidably connected to the outer wall of the fixed track, a fixed frame fixedly connected to the bottom of the ring-shaped plate, a recess formed in the bottom of the ring-shaped plate, and the fixed frame is fixedly connected to the top of the base away from the ring-shaped plate.

[0025] After the equipment is punched, the remaining excess material will be between the two ring-shaped plates and will be limited by the clamping of the two ring-shaped plates, and will stop between the ring-shaped plates.

[0026] Preferably, the limiting assembly comprises a rotating groove formed in the inner wall of the fixed track, a rotating block is rotatably connected to the inner wall of the rotating groove, and a spring plate is fixedly connected to the side wall of the rotating block;

[0027] Wherein, since the clamping force of the two annular plates on the excess material is too large, when the pressure of the pressure assembly on the slide plate decreases, the slide plate will slide upward, and the fixed frame will limit the annular plate from sliding downward along the inner wall of the fixed track, so that the annular plate is misaligned with the top of the fixed track.

[0028] Preferably, the plastic assembly comprises a limiting rod one fixedly connected to the bottom of the top plate, and a plastic block is fixedly connected to the bottom of the top plate;

[0029] Wherein, when the top plate slides downward, the top plate will drive the plastic block to move downward synchronously and contact the outer wall of the plate, at this time, the plastic block cooperates with the plastic groove to complete the processing of the refrigerator stamping part.

[0030] Preferably, the pressure assembly comprises a limiting rod two fixedly connected to the bottom of the top plate, a contact plate is slidably connected to the outer wall of the limiting rod two, and a through hole two is formed in the bottom of the contact plate;

[0031] Wherein, when the top plate moves downward, the contact plate will move downward synchronously, and when the stamping process is performed, the plastic block will pass through the through hole two and contact the top of the plate.

[0032] The present application has the following advantages:

[0033] (1) The present application is aimed at the problem of plate jumping caused by bending of the stamping edge position, and a sliding mechanism is arranged in the equipment, wherein, under normal conditions, the top of the annular plate and the through hole one will be misaligned, and present as Figure 6 When the top plate drives the pressure assembly to extrude the top of the slide plate, the slide plate will drive the fixed track to slide downward along the inner wall of the annular plate, and finally the top of the annular plate and the top of the fixed track will be in a flush state, and then the notch at the bottom of the contact plate will impact the plate, completing the basic punching process, so that the excess material remaining on the plate will accumulate between the annular plates, and present as Figure 7 When the distance between the telescopic rod and the top plate expands again, the spring one forces the slide plate to move away from the base, the base drives the annular plate to move downward through the fixed frame, so that the bending position of the punching edge of the plate is away from the outer wall of the annular plate, reducing the contact surface between the punching bending edge and the annular plate, and the bending edge contacts the outer wall of the chamfer during subsequent sliding, which effectively prevents the phenomenon of plate jumping caused by the bending edge of the hole.

[0034] (2) This invention utilizes the characteristic of the regular up-and-down sliding of the slide plate and sets up a limiting component inside the device. Due to excessive clamping pressure between the excess material and the fixed track, when the slide plate drives the fixed track downwards, the bottom of the rotating block will contact the top of the excess material, and the rotating block will drive the excess material to slide downwards along the inner wall of the annular plate. Conversely, when the slide plate drives the fixed track upwards, the excessive clamping force between the annular plate and the excess material causes the outer wall of the excess material to contact the inclined surface of the outer wall of the rotating block when the fixed track slides upwards, forcing the rotating block to rotate inwards around the connection point, resulting in the following... Figure 8 As shown, at this time, due to the accumulated potential energy, after the residual material completely passes through the restriction of the rotating block, the spring plate will drive the rotating block to rotate outward. During the regular up and down sliding of the slide plate, the residual material will slowly slide down along the inner wall of the ring plate. Through the application of the above components, it is ensured that the residual material after stamping can be discharged downward in an orderly manner, preventing the residual material from being the same size as the through hole one, which would cause the residual material to block the through hole one and affect the output efficiency of the equipment.

[0035] (3) The present invention utilizes the characteristic of the fixed track driving the residual material downward in an orderly manner through the limiting component. A groove is provided inside the equipment. As the fixed track slides up and down, when the residual material passes the lowest set of rotating blocks, as the fixed track continues to slide downward, the rotating blocks will contact the top of the residual material and apply a downward pressure to the top of the residual material, forcing the residual material to slide downward and enter the groove area. Since the inner wall diameter of the groove is larger than the inner wall diameter of the annular plate, when the residual material no longer contacts the inner wall of the groove, the residual material will fall directly downward, completing the material discharge process of the equipment.

[0036] (4) After the ring plate completes the stamping process, the clamping force of the ring plate will drive the excess material to quickly leave the processing area. This design effectively prevents the excess material from contacting the impact part of the contact plate too tightly, or from the shaking caused by the separation of the external stamping machine, which would cause the excess material to fall into the processing area between the contact plate and the slide plate, resulting in excess material inside the stamping die, affecting the subsequent stamping accuracy.

[0067] Wherein, in normal state, the spring 113 will be in the state of extension, and the slide plate 112 will be in the highest position of the slide rod 111, when the top pressure assembly 32 extrudes the slide plate 112, the slide plate 112 slides downward along the inner wall of the slide rod 111, and forces the bottom of the slide plate 112 to contact the top of the base 13.

[0075] Wherein, after the annular plate 212 completes the stamping process, the clamping force of the annular plate 212 will drive the excess material to quickly separate from the processing area, and such design effectively prevents the excess material from being in contact with the impact part of the contact plate 322 too tightly, or the shaking caused by the separation of the external stamping machine, causing the excess material to fall into the processing area between the contact plate 322 and the slide plate 112, causing the excess material to be stored in the stamping die, affecting the subsequent stamping precision.
