A core box specially used for producing the core shell of the front pump cover

Abstract

The invention relates to a mud core box specially used for producing a front pump cover core shell. The mud core box comprises a bottom plate and a core mold, wherein the core mold is arranged on the bottom plate and forms a mold cavity together with the bottom plate; the appearance of the mold cavity is the same as that of the front pump cover core shell; the core mold comprises a bottom die and a plurality of modules; the bottom die is arranged on the bottom plate and the same as one side of the front pump cover core shell in shape; the plurality of modules are enclosed at the periphery of the bottom die and detachably connected together; and the mud core box also comprises a lock mechanism which is used for relatively locking the plurality of modules. By adopting the core mold, the mold cavity which is the same as the front pump cover core shell in appearance is formed by the plurality of modules and the bottom die in a splicing manner; and the stability of the mold cavity is met under the effect of the lock mechanism. In addition, only the lock mechanism needs to be unlocked when the core is taken, then and the plurality of modules enclosed on the bottom die are removed, so that the integrity of the mud core is ensured, the damage to a corner of the mud core is reduced, and meanwhile, the coring efficiency is improved.

Description

technical field [0001] The invention relates to a core box, in particular to a core box specially used for producing the core shell of the front pump cover. Background technique [0002] In the casting process, it is very common to design the corresponding core box according to the specific shape of the product. Usually, the core box is set as a whole, and the sand is directly filled into the sand tank in the box body from the opening of the box or the core box After the core is formed, the core is directly taken from the box body. Obviously, the efficiency of the core is low, and the core is easily damaged. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a core box specially used for producing the core shell of the front pump cover. [0004] In order to solve the above technical problems, the present invention takes the following technical solutions: [0005] A ki...
