Problems solved by technology

[0003] However, there is a shortcoming of the cutting mold at present, that is, the edge of the knife is easy to be damaged, so most mold companies adopt the following two solutions to solve this problem, one is: if figure 1 , figure 2 As shown, the knife edge part uses mold steel inserts (such as SKD11, SKD61, P20, etc.); the second is: as image 3 , Figure 4 As shown, the mold core uses mold steel as a whole. Both solutions have a common disadvantage, that is, the price is high and the development cost is high.
Therefore, in today's economical society and energy-efficient society, both methods have the problem of economic benefits.

Embodiment

[0023] Such as Figure 5 , Figure 6 Shown, a kind of cutter of die-cutting mold comprises knife base, knife body 4, knife edge 5, and described knife base is the lower die kernel 2 of mould, and described knife body 4 electric welding is piled up on the knife base, and described knife edge 5 Electric welding (or argon arc welding) is deposited on the blade body 4 .

[0024] The punching die includes an upper die core 1, a lower die core 2, and a cutter, and a product 3 is arranged between the upper die core 1 and the lower die core 2. The machining process of the tool is as follows:

[0025] 1. CNC machining, the machining tool cuts out a groove along the line of the knife edge;

[0026] 2. Electric welding or argon arc welding, burn a layer of connecting material in the knife edge groove, that is, the knife body;

[0027] 3. Argon arc welding, burn a layer of mold steel material on the connecting material, that is, the knife edge;

[0028] Fourth, CNC machining, milling...

Abstract

The invention relates to a tool for punching a mould. The tool comprises a knife base, a knife blade and a knife edge, wherein the knife base is a lower mould core of the mould; the knife blade is fixedly arranged on the knife base; and the knife edge is fixedly arranged on the knife blade. Compared with the prior art, the tool for punching the mould has the advantages that the service life of the tool is greatly prolonged, the punching effect is good, and the like.

Description

technical field [0001] The invention relates to a tool, in particular to a tool for punching dies. Background technique [0002] At present, the punching dies of felt are mainly divided into two kinds of dies, one is a male and female punching die; the other is a chopping die. The working principle is: squeeze the felt through the knife edge to break it, so as to achieve the purpose of cutting the leftovers of the parts. From the working principle, it is not difficult to see that the peripheral quality of the product made by the punching die is better than that of the cutting die, but from the perspective of development cost, use cost and maintenance, we can easily see that the cutting die is more expensive than the male and female die. Absolute advantage, so it is recognized by most enterprises and many customer service, and currently has a good market prospect. [0003] However, there is a shortcoming of the cutting mold at present, that is, the edge of the knife is easy...
