Description
Technical field
The utility model relates to a kind of casting mould, a kind of specifically casting mould of fluid-flywheel clutch pump impeller.
Background technology
Fluid-flywheel clutch, claim fluid coupling again, mainly constitute by shell, pump impeller, turbine, the accuracy of these component processing directly has influence on the product serviceability, and then there is potential safety hazard easily in component processing specification disunity, and at present, the fluid-flywheel clutch pump impeller adopts the method production of casting mostly, general pump impeller casting mould is not only heavy, complex operation, and the pump impeller that casts out also exists the post-production amount big, problems such as production cost height.
The utility model content
The utility model purpose is to be the deficiency that solves the problems of the technologies described above, and a kind of casting mould of fluid-flywheel clutch pump impeller is provided, its tool flexible operation, moulding uniform specification, low cost and other advantages.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: a kind of casting mould of fluid-flywheel clutch pump impeller, by loam cake, centring ring, core and counterdie are formed, be provided with core between loam cake and the counterdie, core is made up of SMIS and outside core, SMIS is located at the loam cake downside, the SMIS outside is provided with outside core, outside core is stuck on the lower surface of loam cake by the centring ring in its outside, the counterdie center is provided with sprue bush, centring ring is fixedlyed connected by the pin I with loam cake, loam cake is fixedlyed connected by the pin II with SMIS, and centring ring and counterdie are fixed by chock and clamp.
Described SMIS lower end is provided with the iron cover, and the alignment pin that is provided with on the sprue bush withstands on iron and puts, and is provided with vent plug in the pore of middle in-core.
The described centring ring and the counterdie outside are provided with hanging axis.
Described centring ring downside is provided with centre circle.
Described centre circle is connected with the knockout rod that passes centring ring and loam cake.
Beneficial effect is: the utility model method of operating is simple, only each parts just need be assembled in order and can pour into a mould casting, the less labour intensity that reduces the staff of its build; Leave the space between centring ring and the counterdie, be convenient to cast the branch die worker in later stage and do, to the destruction of modular construction, be beneficial to the formed product uniform specification when having reduced to divide mould; The structural design compact and reasonable makes pump impeller casting rate up to 99%, has reduced wastage of material, has reduced the workload in later stage, has improved working (machining) efficiency, has reduced production cost greatly.

Fig. 1 is a structure cutaway view of the present utility model;
Mark is among the figure: 1, clamp, 2, centre circle, 3, counterdie, 4, sprue bush, 5, alignment pin, 6, the iron cover, 7, vent plug, 8, centring ring, 9, the pin I, 10, outside core, 11, core, 12, SMIS, 13, pin II, 14, loam cake, 15, knockout rod, 16, chock, 17, hanging axis.
The specific embodiment
As shown in the figure, a kind of casting mould of fluid-flywheel clutch pump impeller, by loam cake 14, centring ring 8, core 11 and counterdie 3 are formed, be provided with core 11 between loam cake 14 and the counterdie 3, core 11 is made up of SMIS 12 and outside core 10, SMIS 12 is located at loam cake 14 downsides, SMIS 12 outsides are provided with outside core 10, outside core 10 is stuck on the lower surface of loam cake 14 by the centring ring 8 in its outside, counterdie 3 centers are provided with sprue bush 4, centring ring 8 is fixedlyed connected by pin I 9 with loam cake 14, and loam cake 14 is fixedlyed connected by pin II 13 with SMIS 12, and centring ring 8 and counterdie 3 are fixing by chock 16 and clamp 1.SMIS 12 lower ends are provided with iron cover 6, and the alignment pin 5 that is provided with on the sprue bush 4 withstands on the iron cover 6, is provided with vent plug 7 in the pore in SMIS 12.The centring ring 8 and counterdie 3 outsides are provided with hanging axis 17.Centring ring 8 downsides are provided with centre circle 2.Centre circle 2 is connected with the knockout rod 15 that passes centring ring 8 and loam cake 14.
Concrete implementation step is, outside core 10 is placed on the place, lower surface of loam cake 14, SMIS 12 is installed then and centring ring 8 blocks outside core 10, counterdie 3 and sprue bush 4 are installed afterwards, and the temperature with mould after finishing is heated to 200 ℃, by vent plug 7 pressure is adjusted into negative pressure again, to fill with whole cavity until potting syrup in the casting of molten metal injection cast chamber by watering filling tube, slowly reduce temperature then, make the potting syrup coagulation forming, take out and obtain finished product.
