Abstract
The invention provides a fixing structure for cores in a casting mould for cases of mining machinery, which structurally comprises a bottom case and positioning screws, wherein a bottom core is arranged in the bottom case, a transitional core and a top core are arranged on the bottom core, hangers are embedded in the bottom core, tails of the positioning screws are embedded in the bottom core and hooked with the hangers, both the transitional core and the top core are provided with positioning holes inserted with the positioning screws, and lock nuts are screwed at tops of the positioning screws so as to press the top core tightly.
Description
Technical field
The present invention relates to the fixed structure in loam core in a kind of mining machinery box casting mould.
Background technology
Casing is the important composition parts of mining machinery coal pulverizer, will carry huge weight at work, to having relatively high expectations of wear-resisting, heat-resisting, fatigue resistance.In traditional casting process; Loam core in the casting die mostly interfixes in lateral location; Yet receive the influence of mining machinery coal pulverizer casing self structure; The applicant finds that in the design casting die traditional loam core connects fixed structure and inapplicable, therefore need design the wider loam core fixed structure of the scope of application again.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides the fixed structure in loam core in the wider mining machinery box casting mould of a kind of reliable in structure, the scope of application.
Technical scheme of the present invention is; The fixed structure in loam core in a kind of a kind of mining machinery box casting mould with following structure is provided, and it comprises under casing, is provided with the bottom loam core in the under casing; The bottom loam core is provided with transition zone loam core and top layer loam core; It also comprises positioning screw, is embedded with the extension member in the bottom loam core, the afterbody of positioning screw be embedded in the bottom loam core and with hang member hook mutually; Be equipped with locating hole on transition zone loam core and the top layer loam core and also be enclosed within successively on the positioning screw, the top of positioning screw is rotary with lock nut and the top layer loam core is compressed.
After adopting said structure, the present invention has following remarkable advantage and beneficial effect:
Through positioning screw being embedded in the bottom loam core with the extension member; The loam core is compressed the fixing reliable of back positioning screw, and remaining loam core just can superpose successively and be placed on the bottom loam core through locating hole like this, and the mode of screwing through lock nut and positioning screw at last is strained and fixed the loam core; Stability Analysis of Structures, reliable; This structure need not to utilize the side space of mould, receives the influence of mould self structure less, and the scope of application is also relatively wider.
As improvement, also be provided with the concave station that extends along locating hole on the top layer loam core, lock nut is positioned at this concave station and screws the back with positioning screw uses the molding sand sealing.So just can lock nut be hidden in the loam core, less to the influence of the external structure in loam core, help keeping the integrality of loam core structural entity, help the operation of subsequent handling.
Description of drawings:
Fig. 1 is the front view of the fixed structure in loam core in the mining machinery box casting mould of the present invention;
Fig. 2 is the enlarged diagram at A place among Fig. 1;
Fig. 3 is the decomposing schematic representation of the fixed structure in loam core in the mining machinery box casting mould of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
Like Fig. 1, Fig. 2, shown in Figure 3, the fixed structure in loam core in the mining machinery box casting mould of the present invention, it comprises under casing 1; Be provided with bottom loam core 2 in the under casing 1; Bottom loam core 2 is provided with transition zone loam core 3 and top layer loam core 4, and it also comprises positioning screw 5, hangs member 6; Hang member 6 and be embedded in the bottom loam core 2, the afterbody of positioning screw 5 be inserted in the bottom loam core 2 and with hang member 6 mutually hook then the loam core is compressed and can will hang member 6 and fix with positioning screw 5; Be equipped with locating hole 7 on transition zone loam core 3 and the top layer loam core 4; Be enclosed within on the positioning screw 5 then successively; Last screwing with lock nut 8 at the top of positioning screw 5 compresses top layer loam core 4, and so just can whole loam core structure install and fix is relatively good, reliable; And do not receive mould side effect on structure, the scope of application is wider.
As corrective measure; On top layer loam core 4, also be provided with the concave station 9 that extends along locating hole 7; So just can make lock nut 8 time be positioned at this concave station 9 and then fill up concave station 9 sealing then with molding sand 10 with screwing at positioning screw 5 in locking, the globality of loam core structure is better.
