Disclosure of Invention

The purpose of the utility model is as follows: in order to overcome the defects in the prior art, the special-shaped ceramic product forming die is provided, the forming groove of the lower die is replaced by the separable die core, the forming requirements of special-shaped ceramic products with different structures are met under the condition that the lower die is not required to be replaced, the automatic demolding function is realized, the demolding efficiency is improved, the smoothness of batch production of products is ensured, and the production efficiency is improved.

The technical scheme is as follows: in order to achieve the purpose, the utility model provides a special-shaped ceramic product forming die which comprises a bottom plate, a lower die and an upper die, wherein a die core groove and a die core matched in the die core groove are formed in the lower die, the die core is used for being matched with the upper die to form a special-shaped ceramic product forming cavity, the top of the die core is outwards and transversely expanded to form a protruding part, a concave part matched with the protruding part is arranged at the notch of the die core groove, the protruding part is matched on the concave part, a plurality of demoulding grooves are formed in the concave part, a spring part and a demoulding rod are arranged in each demoulding groove, and the spring part is arranged at the bottom end of the demoulding rod and used for ejecting the demoulding rod to realize demoulding of the die core.

Further, the demolding groove is of a circular groove structure, and the demolding rod is of a circular rod structure.

Further, the bottom of the spring piece is welded on the bottom of the demoulding groove, and the top of the spring piece is contacted with the bottom of the demoulding rod.

Furthermore, the protruding portion and the recessed portion are both circular structures, the number of the demolding grooves is four, and the demolding grooves are symmetrically arranged on the recessed portion.

Further, the thickness of the protrusion is equal to the height of the recess.

Has the advantages that: compared with the prior art, the utility model has the following advantages:

1. adopt separable mold core to replace the shaping groove of bed die, need not to change under the condition of bed die, the mold core that can relax, convenient change corresponds has satisfied the shaping demand of isostructure dysmorphism ceramic product not, has solved in the current dysmorphism ceramic product forming die that a bed die corresponds the dysmorphism ceramic product of a structure, needs frequently to change the problem of bed die, has not only practiced thrift and has changed operating time, has reduced use cost moreover.

2. The demoulding rod can automatically eject the mould core out of the mould core groove after the mould is separated by the upper mould under the elastic force action of the spring part, the automatic demoulding function is achieved, a worker can take out the mould core and then finish the taking out of the special-shaped ceramic product, and through the alternative use of more than two mould cores, the fluency of the batch production of the product is guaranteed, and the production efficiency is improved.
