Utility model content
The object of utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of novel casting core side concave surface mould.It by being provided with middle loose piece between upper core box and lower core box, such that the side concave surface of core is shaping becomes more easy, in separation process, middle loose piece takes out with core, taken off by middle loose piece subsequently, the core quality made is intact, can not cause damage in type core, and the middle loose piece taken out can also continue to use, fast convenient for production, improve production efficiency and product quality, provide cost savings simultaneously, and simple and reasonable, be suitable for extensive use.
For achieving the above object, the utility model adopts following technical proposals: a kind of novel casting core side concave surface mould, it comprises core box and lower core box, it also comprises middle loose piece, described middle loose piece is located in the middle of described upper core box and described lower core box, and described upper core box, described middle loose piece, described lower core box fasten the forming cavity forming core from top to bottom successively;
Described upper core box centre position offers the first groove, and described lower core box centre position offers the second groove, and described middle loose piece is located between described first groove and described second groove.
Preferably, the both ends of the surface up and down of described middle loose piece all become convex surface.
Preferably, the two ends up and down of described middle loose piece are all convexly equipped with annular card article.
Preferably, described first groove is provided with the first draw-in groove matched with described annular card article, described second groove is provided with the second draw-in groove matched with described annular card article, and described first draw-in groove coordinates with described second draw-in groove the locating slot forming described annular card article.
Preferably, described middle loose piece becomes symmetrical structure.
The beneficial effects of the utility model are:
1, the utility model passes through by being provided with middle loose piece between upper core box and lower core box, make that the side concave surface of core is shaping becomes more easy, in separation process, middle loose piece takes out with core, subsequently middle loose piece is taken off, the core quality made is intact, damage can not be caused in type core, and the middle loose piece taken out can also continue to use, fast convenient for production, improve production efficiency and product quality, provide cost savings simultaneously, and simple and reasonable, be suitable for extensive use.
2, the utility model is by being arranged on the first groove and second groove in upper core box and lower core box centre position, gives the accurate positioning supports of middle loose piece, ensure that the quality of the core made further simultaneously.
3, the utility model is reasonable in design, and structure is ingenious, is applicable to batch production.
Accompanying drawing explanation

Fig. 2 is the plan structure schematic diagram of lower core box in the utility model;
Fig. 3 is the main TV structure schematic diagram of lower core box in the utility model;
Fig. 4 is the main TV structure schematic diagram of middle loose piece in the utility model;
Fig. 5 is the perspective view of middle loose piece in the utility model;
Wherein go up core box 1, lower core box 2, middle loose piece 3, first groove 1-1, core body 1-3, the second groove 2-1, annular card article 3-1, the first draw-in groove 1-2, the second draw-in groove 2-2.
Detailed description of the invention
Here it should be noted that, the described noun of locality is left and right, upper and lower is all define for benchmark with the view shown in Fig. 1, should be appreciated that the protection domain that the use of the described noun of locality should not limit the application and asks.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figures 1 to 5, a kind of novel casting core side concave surface mould, it comprises core box 1, lower core box 2 and middle loose piece 3, it is middle with described lower core box 2 that described middle loose piece 3 is located at described upper core box 1, and described upper core box 1, described middle loose piece 3, described lower core box 2 fasten the forming cavity forming core from top to bottom successively.
Described upper core box 1 centre position offers the first groove 1-1, and described lower core box 2 centre position offers the second groove 2-1, and described middle loose piece 3 is located between described first groove 1-1 and described second groove 2-1.
As shown in Figure 4 and Figure 5, on technique scheme basis, the both ends of the surface up and down of described middle loose piece 3 all become convex surface, and then make the side of core can form concave surface or other specific shapes.
