Description

Technical Field

[0001] The utility model belongs to the technical field of connector stamping dies, and in particular relates to a stripping plate of a connector stamping die. Background Art

[0002] The stamping die is needed in the production process of connector stamping. The main function of the upper stripper plate in the stamping die is to provide preliminary positioning of the material during the stamping process and to press the material at the beginning of stamping to ensure that the material will not shift due to impact during the stamping process. At the same time, after the stamping is completed, the upper stripper plate is also responsible for separating the formed connector from the die to facilitate subsequent processing or automated equipment grabbing;

[0003] At present, the inserts installed in the stripper plate to cooperate with the punch guide provide precise guiding effect for the punch, so as to ensure the stamping accuracy of the connector by the mold. Conventional insert installation forms include stepped, locking and double-layer types. Among them, the locking and double-layer types require the inserts to be threadedly connected to the stripper plate by bolts, while the stepped inserts are inserted into the positioning stripper plate, which is not convenient for disassembly. The inserts connected by bolts can be removed by removing the screws during installation and debugging. Although the operation is convenient, the screws need to be frequently disassembled and assembled, which is easy to damage the tapping pattern and affect the quality of the stripper plate.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The following is combined with Figure 1-6 To further explain this application in detail,

[0025] The embodiment of the present application discloses a stripper plate of a connector stamping die, comprising a stripper plate 1, wherein the stripper plate 1 is provided with an insert 2 for inserting and guiding a matching punch, the insert 2 is provided with a through hole groove 3 for movably inserting a matching punch, the insert 2 is provided with an internal thread groove 4 connected with the through hole groove 3, after the internal thread groove 4 is threadably connected with the external thread of a drill bit on an electric drill, the insert 2 can be lifted and removed from the stripper plate 1 by lifting the electric drill.

[0026] The stripping plate 1 is provided with an embedding groove 5 for the embedded component 2 to be embedded. A support block 6 is provided in the embedding groove 5 . The embedded component 2 is provided with a limiting block 7 overlapped on the support block 6 .

[0027] An internal thread groove 4 is provided on the insert 2 and is threadedly connected to the external thread of the drill bit on the electric drill. When the insert 2 is installed, it is inserted into and positioned in the embedding groove 5 of the stripping plate 1. The limit block 7 on the insert 2 is located above the support block 6. When the insert 2 needs to be removed, the external thread portion of the drill bit on the electric drill is screwed into the internal thread groove 4. The electric drill is pulled, and the external thread portion of the drill bit will drive the insert 2 to be pulled out of the stripping plate 1, thereby facilitating the removal of the insert 2.

[0028] By screwing the drill bit on the electric drill into the internal thread groove 4 and pulling the electric drill, the insert 2 can be easily removed without removing the entire stripper plate 1, thereby improving maintenance efficiency. Since the insert 2 is threadedly connected with the external thread of the drill bit through the internal thread groove 4 instead of being directly tightened with the screw, direct manual damage to the thread can be reduced, thereby extending the service life of the insert 2 and the stripper plate 1.

[0029] The insert 2 is inserted into the punch through a guide, providing a precise guide for the punch, which helps to ensure the stamping accuracy of the mold on the connector.

[0030] The four corners of the stripping plate 1 are provided with inner guide sleeves 8 which cooperate with the guide rods on the lower die for movable insertion and guidance.

[0031] The inner guide sleeve 8 cooperates with the guide rod on the lower die to provide a better guiding effect, thereby ensuring the accuracy and stability of the stamping process.

[0032] The stripping plate 1 is provided with a limiting sleeve 9, and the limiting sleeve 9 is provided with a screw 10 of equal height that is threadably connected to the upper die.

[0033] The contour screw 10 includes an internal threaded sleeve 11 passing through the limiting sleeve 9, a limiting ring 12 fixed to the outer side of the internal threaded sleeve 11 and limited to the inner side of the limiting sleeve 9, and an external threaded rod 13 threadedly connected to the internal threaded sleeve 11 and to the upper mold.

[0034] The design of the limiting sleeve 9 and the height-conforming screws 10 can increase the stability of the stripping plate 1 and improve the service life of the mold. The height-conforming screws 10 can be easily removed through threaded connection, thereby facilitating the maintenance and care of the mold.

[0035] The stripping plate 1 is provided with a concave groove 14, in which a lower pad 15 is fixed by screws, and the lower pad 15 is connected to an upper pad 17 by a spring 16, and the upper pad 17 is fixed to the upper die by screws. When the punch is punched and sheared, the punch is separated from the connector by the force provided by the stripping spring 16, which can improve the rigidity and stability of the stripping plate 1, reduce deformation and vibration during the stamping process, improve stamping accuracy, and improve the integrity and stability of the connector product during the stripping process of the stripping plate 1, so that the stamped connector is not deformed.

[0036] During the use of the stripper plate of the connector stamping die, the insert 2 cooperates with the punch to guide and intersect, providing a precise guiding effect for the punch, thereby ensuring the stamping accuracy of the die on the connector. When the punch is punched and sheared, the punch is separated from the connector by the force provided by the stripper spring 16. At this time, the stripper spring 16 on the stripper plate 1 will provide a certain ejection force, exert an upward ejection force on the insert 2, and drive the connector to be ejected from the lower die.

[0037] When the insert 2 needs to be removed, the drill bit on the electric drill is screwed into the internal thread groove 4 on the insert 2, and the electric drill is pulled, and the external thread part on the drill bit drives the insert 2 to be pulled out of the stripper plate 1. Since the insert 2 is threadedly connected with the external thread of the drill bit through the internal thread groove 4 instead of being directly tightened with the screw, direct manual damage to the thread can be reduced, thereby extending the service life of the insert 2 and the stripper plate 1.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
