(2) mould datum level place is divided to be respectively provided with positioning plate and location riser in horizontal and vertical, as the reference component of Making mold and use;
(3) according to location riser, the mould of foundry goods being divided into two moulds, two moulds are all with positioning plate and location riser for positioning datum;
(4) according to mould structure, the core of dies cavity is divided into two groups to position riser;
(5) described two groups of cores all position in the horizontal direction with positioning plate;
(6), after mould molding, remove positioning plate and location riser, remove core, then by two die assemblies.
Preferably, location, hole, two groups of location is adopted between described location riser and positioning plate.
Preferably, the mould of described segmentation and location riser adopt common location, hole, location.
Preferably, the mould of described segmentation and positioning plate adopt location, hole, location.
Preferably, described positioning plate arranging locating piece, two groups of cores position with positioning plate in vertical direction each through this locating piece.
Having the beneficial effect that of the mould making method of multi-cavity compound casting of the present invention
1, this method application by positioning plate, makes many molds of assembling die have unified positioning datum, improves the precision of tooling combination assembling, the final inner chamber dimensional accuracy improving foundry goods.
2, this method is by positioning the application of riser, enables two half moulves of foundry goods to be easy to die sinking, also obtains consistent positioning datum simultaneously, improves the relative position accuracy of two half moulves.
3, this method passes through symmetrical structure mentality of designing, it is possible to the effective saving Design of Dies cycle, and improves Design of Dies and the efficiency of mould processing.
4, this method highly versatile, it is adaptable to the intricate casting Design of Dies that various materials, various casting method produce, casting dimension accuracy can improve 1~2 grade on former methodical basis, improves the size qualification rate of foundry goods.

Detailed description of the invention
Now with one preferably possible embodiments and coordinate accompanying drawing describe in detail as follows:
With a Complex Aluminum Alloy part for testpieces, as illustrated in fig. 1 and 2, its mould is undertaken its casting structure by following processing step:
(1) according to foundry goods 1 structure, choosing horizontal parting datum level 2 and vertical point mould datum level 3, wherein horizontal parting datum level 2 is positioned at an end face of foundry goods, and vertical point mould datum level 3 should be positioned at the maximum cross-section place of foundry goods 1 cavity, as shown in Figure 3.
(2) mould datum level place is divided to be respectively provided with positioning plate 4 and location riser 5 in horizontal and vertical, as the reference component of Making mold and use, as shown in Figure 4.
(3) according to location riser 5, the mould of foundry goods being divided into two moulds, two moulds are all with positioning plate 4 and location riser 5 for positioning datum, as shown in Figure 5,6, it is ensured that the accuracy of location.
(4) according to mould structure, the core 7 of dies cavity is divided into two groups to position riser 5, as shown in Fig. 7,8,9.
(5) described two groups of cores 7 all position in the horizontal direction with positioning plate 4;Meanwhile, positioning plate 4 arranging locating piece 8, two groups of cores position 4 with positioning plate in vertical direction each through this locating piece 8, as shown in Figure 10, it is ensured that it combines precision.(such as Figure 10, shown in 11)
