Description
Technical Field
The utility model belongs to the technical field of the casting, specifically a split type wooden core box that facilitates use.
Background
The core box is a technological device for making core sand into a core, and can be made of wood, plastic, metal and other materials. For the cold box process of medium and small size cores, the core box is usually made of wood. The wooden core box is usually composed of two parts which are detachably connected, and a sand core cavity of a core is manufactured at the parting surface position of the two parts of the core box. And injecting core sand into the cavity of the sand core and solidifying, and separating the two parts of the core box from the parting surface to obtain the core.
Due to the material characteristics of wood, the problems encountered in production mainly include: the two parts of the core box deviate when being buckled; because the adhesion characteristics of molding sand, it is comparatively difficult when opening the box, need sometimes to prize two core boxes from the profile of dividing, and the sled utensil can prize bad core box die joint, causes to close the box untight when using once more.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a split type wood core box which is convenient to use, which comprises a left core box, a right core box and a buckling mechanism; the left core box and the right core box are detachably connected through a buckling mechanism; the left core box and the right core box are provided with inner recesses from parting surfaces of the left core box and the right core box, and the two parts are recessed to form a sand core cavity in a buckling state of the left core box and the right core box. The device also comprises at least one group of sizing block mechanisms; each set of sizing block mechanism is provided with a corresponding left sizing block and a corresponding right sizing block which are respectively and fixedly connected with the edges of the parting surfaces of the left core box and the right core box;
in order to leave a gap between the left sizing block and the right sizing block:
the main body of the left sizing block is in a flat plate shape; an inner recess corresponding to the shape of the left sizing block is formed in the parting surface of the left core box, the left sizing block is fixedly embedded into the inner recess, and the right side surface of the left sizing block is arranged on the left side of the parting surface of the left core box;

Specifically, the method comprises the following steps: the buckling mechanism is a latch clamp, the latch clamp has at least two groups, and each group of latch clamps are centrosymmetric. The structure ensures that the forces in the left and right directions on the left and right core boxes are relatively uniform, avoids the phenomenon that one side is subjected to large stress and the other side is subjected to small stress, so that the deformation difference of two sides of the core box made of wood is too large, and is beneficial to locking the core box and reducing the tolerance of a cavity of a sand core.
And further: the latch clip is formed by detachably connecting a hook component, a hook ring and a handle component; the hook component is connected to the outer side face of the left core box, and the hook ring and the handle component are connected to the outer side face of the right core box. Under this structure, when the lock, the pulling force direction of each side of core box all is from left and right, reduces the psammitolite cavity warp circumstances that wooden core box constitutes.
Further: in any group of sizing block mechanisms, the left sizing block and the right sizing block are positioned in the middle of the corresponding side surfaces of the wood core box;
a left iron plate is arranged between the hook component and the outer side surface of the left core box; the left iron plate is in an L shape; the first edge of the left iron plate extends from the left surface of the left core box to the right surface of the left sizing block and is connected with the left sizing block; the second edge of the left iron plate is connected to the left surface of the left core box;
a right iron plate is arranged between the shackle and the handle part and the outer side surface of the right core box at intervals; the right iron plate is in an L shape; the first edge of the right iron plate extends from the left surface of the right core box to the right surface of the right sizing block and is connected with the right sizing block; the second side of the right iron plate is connected to the right surface of the right core box.
Under this structure, latch clamp and parallels mechanism become whole, have avoided latch clamp direct mount to the side of wooden core box, the damage that the softer timber of connecting screw pair core box brought. Namely, the force application area of the latch clamp to the wooden core box is enlarged.
Specifically, the method comprises the following steps: the second edge of the left iron plate is embedded into the left surface of the left core box, and the surface of the second edge of the left iron plate does not protrude out of the left surface of the left core box; the second side of the right iron plate is embedded into the right surface of the right core box, and the surface of the second side of the right iron plate does not protrude out of the right surface of the right core box. The structure ensures that the shape of the core box is smooth.
And the parting surfaces of the left core box and the right core box are respectively connected with corresponding pin holes and pin columns, and the pin columns are inserted into the corresponding pin holes in the buckling state of the left core box and the right core box.
The wooden core box solves the problem that the wooden core box in the prior art is difficult to divide the box, is simple to implement, and can be obtained by modifying the existing wooden core box.
