The specific embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention is described in detail, but is to be understood that protection scope of the present invention does not receive the restriction of the specific embodiment.
Fig. 9 representes is the sketch map that adopts four foundry goods of a type that the present invention casts out.This foundry goods comprises four identical diesel-engine bodies of shape and structure; These four diesel-engine bodies divide two row, two row to arrange; In the horizontal direction; The front end 95 of one of them engine body is relative with the rear end 96 of another engine body, and in vertical direction, the bottom of one of them engine body is relative with the bottom of another engine body.
For casting four foundry goods of an aforesaid type, need six kinds of cores of design altogether:
The 3rd core 3, as shown in Figure 3, the shape and the structure of second cylinder 92 that the forward part 392 of the 3rd core 3 and rear section 393 have diesel-engine body continuously respectively and the inner chamber of the 3rd cylinder 93;
The 4th core 4, as shown in Figure 4, the forward part 495 and the rear section 496 of the 4th core 4 has the front end 95 of diesel-engine body and the shape and the structure of rear end 96 continuously respectively;
The 5th core 5, as shown in Figure 5, the preceding left half 5196 of the 5th core 5, preceding right part 5195, back left half 5295, back right half 5296 have the shape and the structure of rear end 96, front end 95, front end 95 and the rear end 96 of diesel-engine body continuously respectively;
The 6th core 6, as shown in Figure 6, the 6th core 6 has the shape and the structure of the water channel inner chamber of diesel-engine body, and the bottom of core 6 is provided with because the location core print 61 of installing and locating;
Wherein, on the mutual installation contact-making surface of said second core 2, the 3rd core 3, the 4th core 4, the 5th core 5, each contact-making surface is provided with the location core and the positioning seat of locating each other when being used to form the core group respectively.
For casting four foundry goods of an aforementioned type, also be designed with external form apperance and following external form apperance, and use should go up external form apperance and following external form apperance on moulding line respectively moulding go out cope and drag box.
As shown in Figure 7; The said external form apperance that goes up has the left outer shape 797 that is divided into four identical diesel-engine bodies arranging on two row, two column average ground simultaneously, on this in external form apperance among the mutual alignment of the left outer shape 797 of each body and Fig. 1 the putting position of each body adaptive.
As shown in Figure 8; Said external form apperance 8 down has the right outer shape 898 that is divided into four identical diesel-engine bodies arranging on two row, two column average ground simultaneously, also is provided with in the right outer shape 898 of each body owing to the putting position of each body among each body outer shape 898 mutual alignments, a left side and Fig. 1 in positioning seat 861 this time external form apperances 8 of the location core 61 that the 6th core 6 is installed is adaptive.
After making complete core and sandbox respectively, the casting process of can casing.The installation process of core is:
Earlier four the 6th cores 6 are respectively charged into the relevant position of drag box; In drag box, put core more from left to right successively compactly; The order of putting of core is: the 4th core 4, second core 2, the 3rd core 3, the 3rd core 3, second core 2, the 5th core 5, second core 2, the 3rd core 3, the 3rd core 3, second core 2, the 4th core 4; At last in two the inners, front and back of drag box respectively continuously horizontal pendulum be placed with two first cores 1, to form core group shown in figure 10.
The installation of said core also can be carried out by this way: earlier four the 6th cores 6 are installed on the drag box relevant position respectively; Vertically put the 4th core 4, second core 2, the 3rd core 3, the 3rd core 3, second core 2, the 5th core 5, second core 2, the 3rd core 3, the 3rd core 3, second core 2, the 4th core 4 successively with direction from left to right on the workbench outside sandbox again; At this moment; Location core on each core that is in contact with one another and the positioning seat location that cooperatively interacts; Constitute a fixing core group; Use anchor clamps that said core group is put into the relevant position of drag box then, at last in the rear and front end of said core group respectively continuously level respectively put two first cores 1.Adopt such installation method, because the assembling of core is on open platform, to carry out, assembling process is more convenient, thereby can effectively reduce core is packed into time of step of sandbox, and efficient is higher.
Compared with prior art, the present invention uses this core group to carry out once-cast and can obtain four same diesel-engine bodies through reasonably designing core and sandbox, has improved production efficiency effectively, and has practiced thrift production cost.
More than disclosedly be merely a specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
