Abstract
The invention relates to a sand mould demoulding device used for casting, which comprises a horizontal timber frame, a rectangular soleplate and a mold core; wherein, the horizontal timber frame is fixed above the rectangular soleplate by angle irons in four corners; the upper end surface of the horizontal timber frame is connected with a slab; a cavity is mounted in the middle of the slab, which can inosculates with a connection plate of the mold core; the middle of the soleplate is provided with a vertical lift mechanism; the top end of the vertical lift mechanism is connected with the mold core through a supporting plate. When sand mould is molded, the lower end surface of the mold core is raised on the same level of the slab by the vertical lift mechanism, a molding box is put on the upper end surface of the slab for molding; after molding is finished, the mold core can be pulled out from below by the vertical lift mechanism so as to realize demoulding of the sand mould; manually demoulding is omitted; owing to using the vertical lift mechanism, the mold core descends vertically, which can not damage the sand mould and ensure the quality of the sand mould.
Description
Technical field
The present invention relates to a kind of foundry sand type stripper apparatus, contain horizontal frame support, square base plate and core, this horizontal frame support is fixed on square base plate top by four jiaos angle bar.
Background technology
Casting is one of fundamental technology of modern mechanical process industry, so the development of foundry industry indicates the production strength of a country.China has become one of world foundry machinery big country at present, has obtained very big achievement in recent years in the foundry machinery manufacturing.Wherein modal casting method adopts sand casting, traditional foundry sand type the demoulding the time be divided into for two steps: the core that sandbox and bottom thereof is connected with base plate turns; Catch the base plate of banding pattern core vertically to extract.This method need be operated by experienced master craftsman, and not only labour intensity is big, and specification requirement height, and sand mold easy deformation cause casting dimension accuracy to reduce, and have increased the cost of making.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of laborsaving, the on-deformable foundry sand type of sand mold stripper apparatus that is convenient in demoulding.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of foundry sand type stripper apparatus, contain horizontal frame support, square base plate, core and core connecting plate, this horizontal frame support is fixed on square base plate top by four jiaos angle bar, the core lower surface is fixed with the core connecting plate, its innovative point is: described horizontal frame support upper surface is connected with flat board, the center of described flat board have can chimeric core connecting plate cavity; Vertical lifting mechanism is equipped with at described base plate center, and the top of described vertical lifting mechanism is connected with core by supporting plate.
Further, the gap all is housed on four angles of described flat board adjusts bolt, the end face that bolt is adjusted in described gap is against on the upper surface of horizontal frame support.
Further, the structure of described vertical lifting mechanism is: guide pin bushing is fixed on square base plate upper surface, is connected with guide pillar in the described guide pin bushing, and described guide pillar top is connected with supporting plate, is connected with the gear pair of control guide pillar lifting on the cylinder.
Further, be connected with rotating shaft on the described gear pair, described rotating shaft is supported on the base plate by the bearing block of both sides, and end is connected with rocking handle, all is connected with bearing between described rotating shaft and diaxon bearing.
The invention has the advantages that: when carrying out the sand mold moulding, lower surface by vertical lifting mechanism rising core flushes with flat board, sandbox is placed on dull and stereotyped upper surface and carries out moulding, only need after finishing by vertical lifting mechanism core to be pulled out from the below once more, can realize the demoulding of sand mold, need not hand-stripping, and because employing is vertical lifting mechanism, core is vertically descending during the demoulding, can not damage sand mold, has guaranteed the quality of sand mold.

The specific embodiment
As shown in Figure 1, 2, contain horizontal frame support 1, square base plate 2, core 3, core connecting plate 7, angle bar 4, flat board 5, vertical lifting mechanism 6, core connecting plate 7, supporting plate 8.
Above-mentioned horizontal frame support 1 is fixed on square base plate 2 tops by four jiaos angle bar 4, core connecting plate 7 is fixed on the lower surface of core 3, horizontal frame support 1 upper surface is connected with the flat board 5 of placing sandbox, the gap all is housed on four angles of this flat board 5 adjusts bolt 11, the end face that bolt 11 is adjusted in this gap is against on the upper surface of horizontal frame support 1, have at dull and stereotyped 5 center simultaneously can chimeric core connecting plate 7 cavity.So just can carry out moulding by the hemi-closure space that dull and stereotyped 5, core connecting plate 7, core 3, sandbox constitute, and when the demoulding can from below extract the core 3 that is connected with core connecting plate 7, need not to stir sandbox, reduced labour intensity.
For ease of supporting and extract the core 3 that is connected with core connecting plate 7, we are equipped with vertical lifting mechanism 6 at square base plate 2 centers, concrete structure is: the guide pin bushing 9 of vertical lifting mechanism 6 is fixed on the square base plate 2, be connected with guide pillar 10 in the guide pin bushing 9, these guide pillar 10 tops are provided with supporting plate 8, connect gear pair on the cylinder, this gear pair is connected with rotating shaft 13, rotating shaft 13 is bearing on the square base plate 2 by the bearing block 14 of both sides, end is connected with rocking handle 15, all is connected with bearing 17 between rotating shaft 13 and diaxon bearing 14.
We have simplified its structure when realizing guide pillar 10 liftings, with the part of guide pillar 10 as gear pair, the section axial face that is about to guide pillar 10 is processed into spline-simulating, form gear pair with roller gear 12, and this roller gear 12 is connected with rotating shaft 13.
During the sand mold moulding, to need on the core 3 of moulding and the supporting plate 8 that core connecting plate 7 is fixed on vertical lifting mechanism 6, shake rocking handle 15 counterclockwise, roller gear 12 rotates counterclockwise drive guide pillar 10 and moves up, stretch out horizontal frame support 1 until core connecting plate 7, the removable pin 16 of rocking handle 15 is inserted square base plate 2 lower surfaces, because gravity effect, guide pillar 10 promotes roller gear 12 and rocking handle 15 turns round clockwise, make removable pin 16 be stuck in the lower surface of square base plate 2, stop moving down of core 3, at this moment, we can adjust bolt 11 by the gap and adjust dull and stereotyped 5 height, make core connecting plate 7 be positioned at same horizontal plane with dull and stereotyped 5, then sandbox are placed on dull and stereotyped 5 and carry out the sand mold moulding.
During the demoulding, extract the removable pin 16 of the rocking handle 15 of filling in square base plate 2 belows, shake rocking handle 15 clockwise, the gear pair of forming by guide pillar 10 and roller gear 12 11 is communicated with core 3 with core connecting plate 7 and spurs downwards, realize the demoulding, guide pin bushing 9 guarantees that guide pillar 10 moves both vertically in the process that moves down, thereby has realized vertical move of core 3 when the demoulding, avoid sand mold to be bruised, guaranteed the precision of sand mold.Adopt this bottom knockout formula structure, need not to stir sandbox, improved stripping rate when having reduced labour intensity.
