Description
Technical Field
The utility model relates to a sand casting technical field, concretely relates to loam core for sand casting.
Background
The core is commonly called as a loam core or a core and is used for forming the internal structure of the casting during casting. Before casting, the casting is installed in a casting mould, molten metal is poured in and condensed, and then removed when sand is produced, so that a cavity can be formed in a casting. To increase the strength of the core, a skeleton made of iron wire or cast iron, called "core bar", is usually placed inside the core. In metal casting, a metal core is usually removed in time after the metal is solidified.
The loam core is generally formed by two butt joints, and needs to be fastened and connected after the butt joints, so that defects of formed castings are avoided. The operation of the existing sand core is complex when the existing sand core is connected, and the casting efficiency can be seriously influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sand is loam core for foundry goods to prior art's defect and not enough.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a sand is loam core for foundry goods, is including the left core and the right core that dock each other, all be provided with the pouring cavity in left core and the right core, all set up the sprue gate with pouring cavity intercommunication on left core and the right core, its innovation point lies in: the one side that left side core and right core are relative all sets up a set of joint arch, and sets up from top to bottom two sets of joint archs, the joint recess is all seted up again to the one side that left side core and right core are relative, the protruding and joint recess of joint mutually support, set up the screw hole in the joint arch, the through-hole is seted up to the outer wall of joint recess, when the joint recess was inserted to the joint arch, the screw hole overlaps with the through-hole to adopt the bolt to fix.
Furthermore, joint arch and joint recess are semi-circular structure, both clearance fit.
Furthermore, a rotating handle is arranged on the bolt.
After the structure is adopted, the utility model discloses beneficial effect does:
the utility model has simple structure, reasonable design and convenient use; the utility model discloses a set up that the joint is protruding to carry out the joint with the joint recess, it is fixed that rethread bolt and screw hole realization locking to realize being connected between left core and the right core, easy dismounting has effectively improved work efficiency.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Referring to fig. 1-2, a sand is loam core for foundry goods, including left core 1 and right core 2 that dock each other, all be provided with pouring cavity 3 in left core 1 and the right core 2, all set up pouring hole 4 with pouring cavity intercommunication on left core 1 and the right core 2, the relative one side of left core 1 and right core 2 all sets up a set of joint arch 5, and two sets of joint archs set up from top to bottom, the relative one side of left core 1 and right core 2 all sets up joint recess 6 again, joint arch 5 and joint recess 6 mutually support, set up screw hole 7 on the joint arch 5, through-hole 8 is seted up to the outer wall of joint recess 6, when joint arch 5 inserts joint recess 6, screw hole 7 overlaps with through-hole 8, and adopt bolt 9 to fix. Specifically, when pouring is needed, the left core body 1 and the right core body 2 are butted, the clamping protrusions 5 are respectively inserted into the corresponding clamping grooves 6, at the moment, the threaded holes 7 are overlapped with the through holes 8, and then the bolts 9 penetrate through the through holes 8 and the threaded holes 7 to be in threaded fixation, so that the clamping protrusions 5 and the clamping grooves 6 are fixed, namely the left core body 1 and the right core body 2 are fixed; when the left core body 1 and the right core body 2 are disassembled, the left core body 1 and the right core body 2 are separated only after the bolts 9 are disassembled; the whole dismounting process is simple and effective, and the working efficiency is effectively improved.
In this embodiment, joint arch 5 and joint recess 6 are semi-circular structure, are favorable to direction and spacing, and both clearance fit do benefit to the grafting.
In this embodiment, the bolt 9 is provided with a rotating handle, which facilitates the rotation of the bolt 9 without using tools, thereby achieving tightness.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
