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 at work huge weight, to having relatively high expectations of wear-resisting, heat-resisting, fatigue resistance.In traditional casting process, loam core in casting die mostly interfixes in lateral location, but be subject to the impact of mining machinery coal pulverizer casing self structure, applicant finds that in design casting die traditional loam core is connected and fixed structure inapplicable, therefore needs to redesign the loam core fixed structure that the scope of application is wider.
Summary of the invention
For solving above-mentioned technical problem, the invention provides the fixed structure in loam core in the mining machinery box casting mould that a kind of reliable in structure, the scope of application are wider.
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, it comprises under casing, in under casing, be provided with bottom loam core, bottom loam core is provided with transition zone loam core and top layer loam core, it also comprises positioning screw, is embedded with extension member in bottom loam core, the afterbody of positioning screw be embedded in bottom loam core and with hang member phase hook; On transition zone loam core and top layer loam core, be equipped with locating hole and be enclosed within successively on positioning screw, the top of positioning screw is rotary with lock nut and top layer loam core is compressed.
Adopt after said structure, the present invention has following remarkable advantage and beneficial effect:
By positioning screw being embedded in bottom loam core with extension member, after loam core is compressed, positioning screw is fixing reliable, remaining loam core just can superpose successively and be placed on bottom loam core by locating hole like this, the mode finally screwing by lock nut and positioning screw is strained and fixed loam core, Stability Analysis of Structures, reliable, this structure, without the lateral space of utilizing mould, is subject to the impact of mould self structure less, and the scope of application is also wider.
As improvement, on top layer loam core, be also provided with the concave station extending along locating hole, lock nut is positioned at this concave station and screws the rear molding sand sealing of using with positioning screw.So just lock nut can be hidden in loam core, less on the external structure impact in loam core, be conducive to keep the integrality of loam core structural entity, be conducive to the operation of subsequent handling.
brief description of the drawings:
Fig. 1 is the front view of the fixed structure in loam core in mining machinery box casting mould of the present invention;
Fig. 2 is the enlarged diagram at A place in Fig. 1;
Fig. 3 is the decomposing schematic representation of the fixed structure in loam core in mining machinery box casting mould of the present invention.
detailed description of the invention:
Below in conjunction with drawings and the specific embodiments, the invention will be further described.
As shown in Figure 1, Figure 2, Figure 3 shows, the fixed structure in loam core in mining machinery box casting mould of the present invention, it comprises under casing 1, in under casing 1, be provided with bottom loam core 2, 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 bottom loam core 2, the afterbody of positioning screw 5 is inserted in bottom loam core 2 and then loam core is compressed with extension member 6 phase hooks can be by fixing to extension member 6 and positioning screw 5; On transition zone loam core 3 and top layer loam core 4, be equipped with locating hole 7, then be enclosed within successively on positioning screw 5, finally screw top layer loam core 4 is compressed with lock nut 8 at the top of positioning screw 5, installation that so just can whole loam core structure is fixing relatively good, reliable, and be not subject to the impact of mould side structure, the scope of application is wider.
As corrective measure, on top layer loam core 4, be also provided with the concave station 9 extending along locating hole 7, so just can make lock nut 8 when locking be positioned at this concave station 9 and with screw at positioning screw 5 after fill up then sealing of concave station 9 with molding sand 10, the globality of loam core structure is better.
