Abstract
The utility model discloses a core-pulling structure of a core, which comprises a first core and a second core which are arranged side by side, wherein the first core is of a split structure and is formed by coaxially connecting a first core front section and a first core rear section, the two sections are connected by screw threads, the first core front section is made of mold steel, and the first core rear section is made of structural steel; the second mold core is of a split structure and is formed by coaxially connecting a front section of the second mold core and a rear section of the second mold core, and the two sections are connected by adopting a T-shaped groove and a T-shaped block; the front section of the second mold core is made of mold steel, and the rear section of the second mold core is made of structural steel; a supporting block is arranged between the first mold core and the second mold core. The single core of present case adopts two segmentation structures, and the anterior segment adopts the mould steel, and the back end adopts structural steel. If only need the anterior segment damage after the back quick replacement can, more need not wholly change low cost. Meanwhile, the supporting block is additionally arranged, so that the rigidity of the structure can be increased, and the deformation of the mold core is avoided.
Description
Technical Field
The utility model belongs to the casting field especially relates to a core pulling structure of core.
Background
The existing core pulling structure comprises two cores which are arranged side by side, and a connecting structure is not arranged in front of the two cores. Moreover, each core is of an integral structure and adopts high-quality die steel.
Because the length of core is longer, and receive reasons such as aluminium water extrusion when pouring, core front end portion is easy to break, just so can only wholly change whole root core, and with high costs, influences the cast normal clear.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a core pulling structure is provided, want to overcome prior art's defect.
The technical scheme of the utility model as follows: the utility model provides a structure of loosing core of core, includes the first core and the second core that set up side by side, its characterized in that: the first mold core is of a split structure and is formed by coaxially connecting a first mold core front section and a first mold core rear section, the first mold core front section and the first mold core rear section are in threaded connection, the first mold core front section is made of mold steel, and the first mold core rear section is made of structural steel; the second mold core is of a split structure and is formed by coaxially connecting a front section of the second mold core and a rear section of the second mold core, and the two sections are connected by adopting a T-shaped groove and a T-shaped block; the front section of the second mold core is made of mold steel, and the rear section of the second mold core is made of structural steel;
and a supporting block is arranged between the first core and the second core and is simultaneously in sliding fit with the rear section of the first core and the rear section of the second core.
The single core of present case adopts two segmentation structures, and the anterior segment adopts the mould steel, and the back end adopts structural steel. If only need the anterior segment damage after the back quick replacement can, more need not wholly change low cost. Meanwhile, the supporting block is additionally arranged, so that the rigidity of the structure can be increased, and the deformation of the mold core is avoided, thereby better overcoming the defects of the prior art.
In the scheme, a T-shaped block is arranged at the rear end of the front section of the second mold core, and a T-shaped groove is correspondingly formed at the front end of the rear section of the second mold core.
In the scheme, the diameter of the first mold core is larger than that of the second mold core.
Has the advantages that: the single core of present case adopts two segmentation structures, and the anterior segment adopts the mould steel, and the back end adopts structural steel. If only need the anterior segment damage after the back quick replacement can, more need not wholly change low cost. Meanwhile, the supporting block is additionally arranged, so that the rigidity of the structure can be increased, and the deformation of the mold core is avoided, thereby better overcoming the defects of the prior art.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1, the core pulling structure of the core comprises a first core 1 and a second core 2 which are arranged side by side, wherein the diameter of the first core 1 is larger than that of the second core 2. First core 1 is split type structure to by first core anterior segment 1a and first core back end 1b coaxial coupling form, these two sections adopt threaded connection, and the material of first core anterior segment 1a is the mould steel, and its trade mark is 8407. The material of the first core rear section 1b is structural steel, and the grade thereof is 45# steel. The second mold core 2 is of a split structure and is formed by coaxially connecting a front section 2a of the second mold core and a rear section 2b of the second mold core, and the two sections are connected by a T-shaped groove and a T-shaped block. The rear end of the front section 2a of the second core is provided with a T-shaped block, and the front end of the rear section 2b of the second core is correspondingly provided with a T-shaped groove. The material of the front section 2a of the second core is die steel, and the grade is 8407. The material of the second mold core rear section 2b is structural steel, and the grade thereof is 45# steel. A supporting block 3 is arranged between the first core 1 and the second core 2, and the supporting block 3 is simultaneously in sliding fit with the first core rear section 1b and the second core rear section 2 b.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
