Abstract
The utility model discloses a piston roughcast casting die, which belongs to a special die for casting piston roughcast. The outer die body (2) comprises left and right two parts, and the center is a cylinder cavity with a combined core inside. A bottom core (10) is positioned at the bottom. The combined core comprises a cuneal middle core (4) at the center, two big side cores (12) positioned at the two side of the middle core symmetrically and lengthways, two small side cores (3) positioned at the two side of the middle core symmetrically and breadthwise, and axis pin core which composes piston pin hole (11). A side cavity (7) is left at a side of the piston roughcast cavity (8) and the side cavity bifurcate towards up which form casting gate (6) and riser (5). That means the gate and the riser at the same side, and adopt same side cavity as passage, to reduce the casting space and also the metal liquor dosage. The utility model has the advantages of high efficiency and economy on energy sources.
Description
[technical field] the utility model relates to a kind of mould, particularly belongs to a kind of particular manufacturing craft that is used for the cast pistons blank.
[background technology] piston is the key components and parts of engine, along with the fast development of China's automobile industry, sharply increases for the demand of piston, therefore is badly in need of improving the working (machining) efficiency of piston.At present under the technical conditions, the casting of piston blank relies on manual finishing more, the both sides that are distributed in mould because of the cast gate and the rising head of existing mold, cause the idle space more than needed beyond the blank body in the mould bigger, consume more molten metal, thereby cause the waste of the energy, and increased the workload of next procedure, reduced production efficiency virtually.
[summary of the invention] the purpose of this utility model promptly is to provide a kind of novel piston blank casting mould, to reduce the idle space of mould inside, reaches and reduces the molten metal consumption, enhances productivity and the purpose of energy savings.
Piston blank casting mould provided by the utility model, its outer die body (2) by about two assembled, a side of two outer die bodys (2) by bearing pin (1) string knot together, opposite side sets up ring block (9) separately, in order to fixing with connecting after both assembly units; The central authorities of outer die body are drum shape cavity, wherein place the combination inner core, and end core (10) is installed in the bottom; Described combination inner core comprises two big limit cores (12), two little limit cores (3) of SMIS both lateral sides symmetric arrangement and the bearing pin core (11) that constitutes piston pin hole that the vertical bilateral symmetry of wedge shape SMIS (4), the SMIS of middle position is arranged; It is characterized in that outer die body is reserved with chamber, limit (7) with a side of the piston blank cavity (8) that combination inner core, end core are constituted, chamber, described limit (7) constitutes cast gate (6) and rising head (5) respectively to upper bifurcation.
Piston blank casting mould provided by the utility model, its cast gate and rising head are positioned at the same side, and chamber, a shared limit is as passage, thereby have saved the casting space in the mould, reduced the consumption of molten metal, had the good effect of enhancing productivity with energy savings.
[description of drawings] accompanying drawing partly discloses specific embodiment of the utility model, is further described below in conjunction with accompanying drawing:
Fig. 1, the utility model elevation cross-sectional view;
Fig. 2, the utility model is overlooked part sectioned view.
[specific embodiment] as shown in Figure 1 and Figure 2, piston blank casting mould disclosed in the utility model is suitable for manual operations.One side of its two outer die bodys (2) is tied together by bearing pin (1) string, and opposite side sets up ring block (9) separately.Fixing by ring block (9) connection after two outer die bodys (2) assembly unit, can pour into a mould this moment; After pouring into a mould the cooling that finishes, with two outer die bodys separately, workpiece is taken out.After the outer die body assembly unit, its central authorities form the cavity of drum shape, its bottom fixed installation end core (10), and the combination inner core is placed in the top.Described combination inner core comprises two big limit cores (12), two little limit cores (3) of SMIS both lateral sides symmetric arrangement and the bearing pin core (11) that constitutes piston pin hole that the vertical bilateral symmetry of wedge shape SMIS (4), the SMIS of middle position is arranged.Above-mentioned feature and pot type piston mould are basic identical, so need not too much illustrate.
Characteristics of the present utility model are, after outer die body and combination inner core, the end core assembly unit, consist of One side of piston blank cavity (8) is reserved with chamber, limit (7), and this chamber, limit (7) is to upper bifurcation, respectively Consist of cast gate (6) and rising head (5), namely cast gate and rising head are positioned at the same side, share the chamber conduct of a limit Passage. So, to compare with the pot type piston mould, the utility model has been saved the casting space in the mould, Reduced the consumption of molten metal, thereby had the advantages that to enhance productivity with energy savings.
