Problems solved by technology

However, since the outer mold is a hard mold and the inner mold is a soft mold, once the impact force is large during work, it is easy to cause the outer mold to break when the inner mold is greatly deformed, and its bearing capacity is still not high.
In addition, the structure of this kind of mold is relatively complicated, the manufacturing cost is high, and the development cycle of the mold is long

Embodiment 1

[0032] Such as figure 1 , figure 2 and image 3 As shown, the hot forging composite die includes an inner mold body 1 and an outer mold body 2 . The inner mold body 1 is block-shaped, and the inner mold body 1 is an integral cylinder. A concave mold cavity 11 is opened on the inner mold body 1 . The shape of the mold cavity 11 here can be designed as required. The outer mold body 2 is an integral structure, and the outer mold body 2 is provided with a concave inner mold mounting seat 21. The shape of the above-mentioned inner mold body 1 matches the shape of the inner mold mounting seat 21, and when the inner mold body 1 is installed When entering the inner mold mounting seat 21, the mold cavity 11 faces the outside of the inner mold mounting seat 21.

[0033] The bottom of the outer mold body 2 is provided with an exhaust hole 22 communicating with the inner mold mounting seat 21 . The outer wall of the inner mold body 1 is in sealing fit with the inner wall of the inn...

Embodiment 2

[0047] Such as Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the shape of the inner mold body 1 is an elliptical cylinder, and the shape of the inner mold body 1 matches the shape of the inner mold mounting seat 21 . The rest are the same as in Example 1, and will not be repeated herein.

Abstract

The invention provides a method for manufacturing a hot forging composite die and a hot forging composite die, which belong to the technical field of machinery. It solves the technical problems such as the composite mold is easy to break, the bearing capacity is low, the structure is relatively complicated, the manufacturing cost is high, and the development cycle is long. The manufacturing method of the hot forging composite mold includes material selection and preparation of the mold body, mold body processing and processing of the cavity and assembly, the hot forging composite mold includes an inner mold body and an outer mold body, the inner mold body is in block shape, and the inner mold body There is a concave mold cavity, and a concave inner mold mounting seat is opened on the outer mold body. The shape of the inner mold body matches the shape of the inner mold mounting seat, and the cavity faces The outside of the inner mold mount. The manufacturing method of the invention has the advantages of simple process, short development period and low development cost. The mold has the characteristics of soft outside and rigid inside, strong bearing capacity, long service life, simple structure, saving a large amount of forging material, and high forging quality.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a manufacturing method of a hot forging composite die and a hot forging composite die. Background technique [0002] A hot forging die is a die used to forge hot metal into shape. During die forging, the blank metal can be made into a forging through deformation, which requires the die to exert a great force on the blank metal to achieve the predetermined effect. Since the blank metal will give the mold a reaction force when it is deformed by force, it will usually cause a certain amount of deformation of the mold. Due to the continuous operation, the mold will be deformed, and the quality of the product is difficult to be guaranteed. In addition, the existing molds are usually monolithic. The development of the mold is designed and manufactured according to the needs. The mold is not standardized. Every time the mold is made, it needs to go through blanking-rough machining...
