Problems solved by technology

It is a very good method for the manufacture of small and medium-sized molds, but for the manufacture of very large molds, due to the heavy weight of the mold, this method is easy to cause the mold core made of tungsten steel to be subjected to high pressure and crack, resulting in the scrapping of the mold. Once the entire mold core is worn out during the pressing process, it cannot be repaired and can only be replaced as a whole

Embodiment Construction

[0007] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0008] As shown in the attached figure, it is a middle mold core for manufacturing large molds. The core is composed of tungsten steel block 1, tungsten steel block 2, tungsten steel block 3, and tungsten steel block 4 to form a whole core.

[0009] Under heavy pressure, there is a buffer between the tungsten steel blocks, and the tungsten steel blocks are not easy to crack, and if the middle mold is worn during use, it only needs to be re-wrapped 5, the core can be reuse...

Abstract

The invention discloses a middle mold core for manufacturing a large mold. The mold core is formed by splicing various blocks. The middle mold core has the advantages that the mold core is formed by splicing the blocks into a whole, after the mold is stressed, the spliced mold core has the buffering function and has less possibility of being cracked and damaged, and the scrap rate of the mold core is reduced; and when the mold core is worn in the pressing process, only the worn blocks are required to be replaced or the blocks are required to be spliced into a full mold core so as to form a cavity, the mold core still can be utilized, and the cost is reduced.

Description

technical field [0001] The invention relates to a mold core for making a mold, in particular to a middle mold core for making a large mold. Background technique [0002] The traditional mold core is to insert the whole tungsten steel and the outer material by heat sleeve or cold pressing. It is a very good method for the manufacture of small and medium-sized molds, but for the manufacture of very large molds, due to the heavy weight of the mold, this method is easy to cause the mold core made of tungsten steel to be subjected to high pressure and crack, resulting in the scrapping of the mold. Once the entire mold core is worn out during the pressing process, it cannot be repaired and can only be replaced as a whole. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the present invention is to provide a middle mold core suitable for manufacturing large-scale molds, reduce scrap products and save costs. [0004] Tech...
