Description

HDMI terminal stamping die

Technical Field

The utility model relates to the technical field of dies, in particular to a die for stamping an HDMI terminal.

Background

The mould is used for producing various moulds and tools of the needed products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods in industry. In short, a mold is a tool used to make a molded article, which is made up of various parts, with different molds being made up of different parts. The processing of the appearance of the article is realized mainly by changing the physical state of the formed material. The term "industrial mother" is used.

The stamping die is provided with a plurality of stamping holes for the stamping knives to pass through, the existing stamping die consists of a fixed knife edge cushion block, a movable cushion block and a knife edge, and the fixed knife edge cushion block, the movable cushion block and the knife edge are provided with a plurality of stamping holes for the stamping knives to pass through. Meanwhile, the HDMI connector terminal is precise, so that the whole volume of the stamping die is small, the thickness of the knife edge is only 8.0mm, and the bearable strength is poor, so that stamping holes consistent with the knife edge are required to be formed in the fixed knife edge cushion block and the movable cushion block, and when the stamping knife passes through, the stamping knife is contacted with the inner wall of the stamping knife, thereby reducing the strength of the stamping knife to the knife edge and further reducing the abrasion of the knife edge. However, a plurality of punching holes for the punching cutters to pass through are formed in the fixed cutter edge cushion block and the movable cushion block, so that the manufacturing cost of the die is increased. Therefore, there is a need for improvements to existing stamping dies.

Disclosure of Invention

In view of the above, the present utility model aims at overcoming the drawbacks of the prior art, and its primary object is to provide a die for stamping HDMI terminals, which can effectively solve the problems that the knife edge of the existing stamping die cannot withstand high strength, is easy to wear and has high overall manufacturing cost.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

a die for stamping an HDMI terminal comprises a movable cushion block and a knife edge; the movable cushion block is arranged on external stamping equipment, and is provided with a through hole for a stamping knife to pass through; the knife edge is arranged on the movable cushion block, a plurality of terminal punching holes for the punching knife to pass through are formed in the knife edge, the terminal punching holes are communicated with the through holes, the terminal punching holes are distributed at left and right intervals, and each terminal punching hole is a strip-shaped hole extending forwards and backwards.

As a preferable scheme, the bottom of the movable cushion block downwards extends to form a positioning foot which is installed and positioned with external stamping equipment.

As a preferable scheme, the through hole is a square hole, the square hole is matched with the stamping knife, and when the position of the stamping knife deviates, the stamping knife cannot pass through the through hole, so that the reject ratio of a stamped product is reduced.

As a preferable scheme, the thickness of the knife edge is 20mm, and the design of 20mm thickness is extremely cost-effective because of the traditional fine hole discharge line machining mode and the charge is charged by 20mm of the base thickness.

Compared with the prior art, the utility model has obvious advantages and beneficial effects, and in particular, the technical scheme can be as follows:

through set up a through-hole that supplies the punching press sword to pass through on the movable cushion, and a plurality of terminal punching press holes that supply the punching press sword to pass through have been seted up on the edge of a knife again, a plurality of terminal punching press holes all communicate the through-hole, through the thickness of extension edge of a knife, improve edge of a knife intensity and make the edge of a knife can bear high strength, be difficult to wearing and tearing to the whole cost of manufacture of mould has been reduced to two-piece structure.

In order to more clearly illustrate the structural features and efficacy of the present utility model, the present utility model will be described in detail below with reference to the accompanying drawings and examples.

Detailed Description

Referring to fig. 1 to 4, a specific structure of a preferred embodiment of the present utility model is shown, which includes a movable pad 10 and a knife edge 20.

The movable cushion block 10 is arranged on external stamping equipment, and a through hole 11 for a stamping knife to pass through is formed in the movable cushion block 10; in the present embodiment, the bottom of the movable cushion block 10 extends downward to form a positioning foot 12 for positioning with an external punching device; in addition, the through hole 11 is a square hole, the square hole is matched with the stamping knife, and when the position of the stamping knife deviates, the stamping knife cannot pass through the through hole 11, so that the reject ratio of a stamped product is reduced.

The knife edge 20 is arranged on the movable cushion block 10, a plurality of terminal punching holes 21 for a punching knife to pass through are formed in the knife edge 20, the plurality of terminal punching holes 21 are communicated with the through holes 11, the plurality of terminal punching holes 21 are distributed at intervals left and right, and each terminal punching hole 21 is a strip-shaped hole extending forwards and backwards; in this embodiment, the thickness of the knife edge 20 is 20mm, and the design of 20mm thickness is very cost-effective because of the conventional machining method of the thin hole discharge line, which is charged by 20mm of the base thickness.

The design focus of the utility model is that: through set up a through-hole that supplies the punching press sword to pass through on the movable cushion, and a plurality of terminal punching press holes that supply the punching press sword to pass through have been seted up on the edge of a knife again, a plurality of terminal punching press holes all communicate the through-hole, through the thickness of extension edge of a knife, improve edge of a knife intensity and make the edge of a knife can bear high strength, be difficult to wearing and tearing to the whole cost of manufacture of mould has been reduced to two-piece structure.

The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the technical scope of the present utility model, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present utility model are still within the scope of the technical solutions of the present utility model.
