Description
Technical field
The utility model belongs to casting die technical field of mold, is specifically related to the embedded core box cast pattern in a kind of casting and molding operating process, and this apperance and core box are integrally formed, and when utilizing Mold Making type hole, have also completed core making.
Background technology
In casting technology field, referring to Fig. 1, foundry goods A is generally porose, when Foundry Production, generally need to make apperance (being external mold 1 ') and core box 2 ' two cover apperances, core box 2 ' consists of core box fixed bin 2-1 ' and core forming blocks 2-2 ', utilizes apperance 1 ' shape forming hole 5-1 ', utilizes core box to make core 4 '; When mould assembly operates, referring to Fig. 2 a, 2b, core is put into corresponding core locating hole, forms die cavity 5-2 '.
In above-mentioned molding operation, need two to overlap independently mould, and moulding and coremaking are two independently operations, and when core mould assembly operates, there is position error in core and type hole, causes core position and actual requirement position inconsistent, and casting accuracy is relatively low.
Summary of the invention
The problems referred to above that exist for solving prior art, the utility model discloses a kind of embedded core box casting die.
The utility model is taked following technical scheme: a kind of embedded core box casting die, comprise apperance, core type piece, fixed frame, and the thickness of described apperance, core type piece and fixed frame equates; The apperance type hole required with cast casting technique is corresponding, and apperance forms through hole, is fixedly connected with described fixed frame in through hole, and the surrounding inwall of fixed frame takes the form of inclined plane, the inclined-plane of surrounding inwall towards and gradient all consistent; Described core type piece forms by horizontally-spliced by least two, and core type piece forms the core forming hole consistent with core shape, and the surrounding outer wall of core type piece forms the inclined plane shape suitable with fixed frame surrounding inwall, is slidably matched between the two.
Preferably, the middle part of apperance forms described through hole, and through hole is square-shaped.
Preferably, four inwalls of apperance through hole take the form of inclined plane, inclined-plane towards and gradient all identical; Corresponding, fixed frame is square frame shape, and the wall all round of fixed frame also takes the form of inclined plane, and the wall all round of fixed frame is affixed on the inwall of apperance through hole and is fixedly connected with.
Preferably, the rounded shape of fixed frame or polygon-shaped.
The utility model provides a kind of casting mould structure, a kind of embedded core box casting die specifically, in this technical scheme, Core Box becomes separation-type structure, whole core box is comprised of fixed frame, core type piece, the shape of type piece endoporus is corresponding with core shape, and type piece outer wall and fixed frame are formed with the structure that is slidably connected of constant slope.According to the complexity of core, core type piece can be two or polylith formation, and simple core can be made cores by two type pieces, and complicated core need be configured to by polylith type piece, and fixed frame is directly embedded in apperance and forms and be fixedly connected.Before moulding, core type piece is sleeved in certain sequence and in fixed frame, forms knockout core structure; During molding operation, in molding operation process, molding sand is inserted in the core apertures of core type piece composition, recharged external model hole sand; When stripping operation, first utilize the tapering slip cooperating relationship of core type piece and fixed frame, first outer moulding/demoulding, then polylith core type piece is unclamped to surrounding.By aforesaid operations step, core is moulding on type hole directly, the moulding of type hole and core is made and together completed, thereby reduce molding operation program, has reduced Mold Making cost, and has improved core positioning precision.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model preferred embodiment is elaborated.
Referring to Fig. 3,4, for core all at the foundry goods of a core, the present embodiment becomes separation-type structure by Core Box, it comprises apperance 1, core type piece 2, fixed frame 3, the shape of the apperance 1 type hole required with cast casting technique is corresponding, its middle part offer square through hole, four inwall 1-1 of through hole take the form of inclined plane, inclined-plane towards and gradient all identical.Wall all round and four inwalls of fixed frame 3 also take the form of inclined plane, and the inclined-plane of inside and outside wall towards and gradient identical, the height of fixed frame 3 equates with apperance 1, it packs in the square through hole of apperance 1, and its all round wall be affixed on apperance 1 square through hole inwall and be fixedly connected with.The core type piece 2 that core is made by two or more than two forms, and general circular core is by two core type piece 2 horizontally-spliced forming, and complicated core needs a plurality of core type pieces 2 horizontally-spliced and form.The present embodiment is selected two core type pieces.By two horizontally-spliced monolithic devices pieces that form of core type piece 2, its middle part (being inwall) forms the endoporus 2-1 suitable with core shape, outer wall 2-2 forms the inclined-plane corresponding with the inwall inclined-plane of fixed frame 3, the height of core type piece 2 equates with the height of fixed frame 3 and apperance 1, it inserts fixed frame 3 endoporus, between both walls, be slidably matched, thereby formed inserted core box structure.
Adopt the embedded core box casting die molding operation process of above-described embodiment as follows:
1) first the apperance with fixed frame 31 is placed on baffle plate 4, then within putting into sandbox 5, prepares molding operation, as shown in Figure 5.
2) two core type pieces 2 are put into the fixed frame 3 of apperance, as shown in Figure 6.
3) before moulding hole, first the molding sand in core box is filled up, make core 6, as shown in Figure 7.
4) on core, insert arbor 7, to guarantee that core is better connected with outer molding sand, as shown in Figure 8.
5 insert making type hole in sandbox by sand, as shown in Figure 9.
6) mould turnover, takes out apperance 1, as shown in Figure 10 a, 10b.
7) two core type pieces 2 unclamped and taken out to surrounding, can complete and carry out the molding operation process that type hole makes and core is made simultaneously, having formed die cavity, as shown in Figure 11 a, 11b.
From above embedded core box apperance molding operation step, can find out, adopt technical solutions of the utility model, core is made with apperance type hole and is completed in same operation, thereby reduced molding operation link, improved moulding productivity ratio, and improved the positioning precision of core, also reduced number of molds simultaneously.
The utility model is specially adapted to following casting structure: the one, and sand cores of castings needs all in a sandbox; The 2nd, sand cores of castings boring ratio foundry goods overall dimensions are little, and both sizes differ larger, can make casting die have enough spaces and form embedded core mould structure.
Those of ordinary skill in the art will be appreciated that; above embodiment is only for the utility model is described; and be not that conduct is to restriction of the present utility model; as long as in essential scope of the present utility model, to the variation of the above embodiment, modification, all will fall into protection domain of the present utility model.
