Device for producing case core

The utility model relates to a device for producing case core, comprising a core shooter, a left mould body, a right mould body, a fixing plate, a connecting plate, a pushing plate, an ejecting rod, etc. A core pulling mechanism is provided at the position vertically opposite to a mould cavity formed by the matched mould of the left mould and the right mould. The core pulling mechanism comprises a central removing cylinder, a connecting block, a positioning block and a core shaft. The connecting block is connected with the central removing cylinder, the positioning block is connected with the connecting block through screws, the lower end of the core shaft is connected with the positioning block, and the upper end of the core shaft is inserted into the mould cavity. Therefore, the core shooting mould can adopt the analogous core pulling mode to carry out the core pulling operation of the solid sand core to achieve the purpose of the case core production. The utility model is improved on the base of the original core shooter, the existing equipment is effectively used, and the production cost is reduced. Compared with the special case core machine, the requirement of the production condition is low, and the production quality is improved.
