The purpose of this utility model is realized by following technical scheme.
A kind of two inlet turbine case core box structure, comprise dynamic model and quiet mould, be provided with two corresponding mutually snail hull shape core cavitys in this dynamic model and the quiet mould, the top of core cavity is provided with the core that is connected with the core cavity and penetrates Sha Kou, snail hull shape core cavity and penetrate and be provided with an entrance channel between the sand mouth; It is characterized in that: the corresponding mutually middle part that respectively is arranged on dynamic model and quiet mould of snail hull shape core cavity in dynamic model and the quiet mould, respectively be provided with a positioning block in the both sides of dynamic model snail hull shape core cavity, this locating piece is fixed on the dynamic model; Both sides at quiet mould snail hull shape core cavity respectively are provided with a slideway, and a slide block respectively is installed in the groove of slideway, between slide block and the slideway for movingly; The both sides of quiet mould respectively are fixed with a fixed dam, respectively are provided with a through hole on the fixed dam of both sides, pass a bolt in the through hole respectively, and this bolt links together with the screw that is located on the slide block, and spring respectively is installed on the bolt; Dynamic model and the mutual correspondence of quiet mould snap together and constitute an one-piece core box.
Bolted mode is adopted in the both sides of described slideway, and each fixes two location-plates.
Described spring is installed in respectively between the nut and fixed dam on the bolt.
Described slide block be shaped as the bucking ladder shape, and the two bottom sides of bucking ladder shape slide block respectively extends outward a boss.
Described locating piece and slide block match and are the bucking ladder shape, and adopt bolt connecting mode to be fixed on the dynamic model.
Be that corresponding mutually face contacts between the slide block on locating piece on the described dynamic model and the quiet mould, and each other for movingly.
One side of described boss is the arcwall face that matches with snail hull shape core cavity shape.
The beneficial effects of the utility model: two snail hull shape ox core core boxes that the utility model will separate are modified into the whole two inlet turbine case core box structures of a cover, it can be produced the integral sand core one-shot forming naturally, avoided because snail hull shape Niu Xin is made in two, after getting core, the core cavity that bonding by manually carrying out again, finishing etc. caused produces the generation of fash problem, has improved qualification rate and the product quality of snail hull shape Niu Xin; Simultaneously, save the operation of sticking core, coremaking operation is raised the efficiency 2 times, thereby has improved production efficiency, has reduced cost.
