Described upper mold edge is that border is divided into the first inner core and the first die cavity more than the concentric circular of water inlet flange excircle, described first inner core is divided into four the first loose pieces, and each first loose piece is divided into the upper and lower, and the upper and lower removably connect, the contact surface of upper strata and the first die cavity sets and is inlaid with Magnet, is removably connected by Magnet and the first die cavity；
Described lower mold is divided into the second inner core and the second die cavity with the circle of corresponding armored pump lid mouth for circumscribed circle, wherein, second inner core is divided into again the pentagon block at center and is positioned at five the second loose pieces of pentagon block periphery, described second loose piece is divided into upper, middle and lower three layers, and each layer all removably connects with pentagon block；
Being divided into two sections with linkage section corresponding position along water inlet flange perpendicular bisector in lower mold, wherein one section is connected with water inlet flange corresponding position, and another section is connected with belt section corresponding position；
The water inlet flange of water pump and outlet flange are provided with screw hole, and described screw hole is made in upper mold or lower mold in the way of loosing core.
As preferably: described concentric circular diameter 15mm bigger than water inlet flange.
As preferably: pentagon block and the second loose piece removably connect specifically, pentagon block is provided with groove, the second loose piece is provided with the projection inserted in groove.
Compared with prior art, it is an advantage of the current invention that: mould is divided into upper die and lower die, and after being split by this case method, the mould one-shot forming made, need not be divided into three pieces to carry out bonding as original process, solve the bonding problem that needs after froth pulp is produced, avoid froth pulp change of geometry in bonding process, ensure that the accuracy of size, additionally, the whole one-shot forming of screw hole on intake-outlet flange and outlet flange is worked it out, and eliminates the operation in following process hole.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1: see Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of water pump mould, the water pump made includes armored pump lid mouth, runner, water inlet flange and outlet flange, described runner includes being positioned at the belt section in the middle part of water pump and connecting the section linkage section 7 with water inlet flange that goes in ring, water pump mould is divided into upper mold 1 and lower mold 4 along the face of parallel water inlet, corresponding pump intake flange side is upper mold 1, corresponding armored pump lid and runner side are lower mold 4, and outlet flange and linkage section 7 are integrally located at lower mold 4；
Described upper mold 1 is along being that border is divided into the first inner core and the first die cavity 2 more than the concentric circular of water inlet flange excircle, described first inner core is divided into four the first loose pieces 3, and each first loose piece 3 is divided into the upper and lower, and the upper and lower removably connect, the contact surface of upper strata and the first die cavity 2 sets and is inlaid with Magnet, is removably connected by Magnet and the first die cavity 2；
