Example Embodiment

[0038] Example 1

[0039] Taking the casting mold of the three-slot V-belt pulley 4 as an example to illustrate the casting process of the present invention, the aluminum alloy is used to make the mold cores with reference to the shape of the three-slot V-belt pulley 4. When casting, sand is added on the ground first, Level, put the lower mold 3 upside down on the sand surface, put in the lower mold core 7 and the mud core 8 in turn, supplemented by the sand compaction, and buckle on the ground; refer to the process of the lower mold 3, lift the handle of the middle mold 2 15. Put the middle mold 2 on the sand surface, and put the middle mold core 5, the auxiliary mold core 13 and the mud core 8 in sequence, and the middle mold core 5 is divided into middle mold core blocks 5-1, 5-2, and 5 -3, 5-4 four pieces, supplemented with sand for compaction, mold removal, and then align the pin 11 or tenon 14, put the middle mold 2 on the lower mold 3; the same process as the lower mold 3,...

[0040] Example 2

[0041] Take the casting mold of the double-slot V-belt pulley 19 as an example to illustrate the casting process of the present invention. The aluminum alloy is used to make the mold cores with reference to the shape of the double-slot V-belt 19. When casting, sand is added on the ground first, Level, put the lower mold 3 upside down on the sand surface, put the lower mold core 7 and the mud core 8 in turn, and the sand will be three-dimensionally oscillated to compact and buckle down on the ground; refer to the process of the lower mold 3, set the middle mold 2 Put it on the sand surface, put in the middle mold core 5, the auxiliary mold core 13, and the mud core 8 in turn. The middle mold core 5 is divided into middle mold core blocks 5-1, 5-2, 5-3, 5-4 Four pieces, supplemented with sand for three-dimensional oscillation and compaction, mold out, then align the pin 11 or tenon 14, put the middle mold 2 on top of the lower mold 3; the same process as the lowe...

Abstract

The invention discloses a casting mould of a belt pulley with a groove, comprising an upper die, a lower die, die cores, mud cores and a sprue. The casting mould is characterized in that a middle die is arranged between the upper die and the lower die; positioning connections between the upper dies and the lower die as well as between the middle die and the lower die are both realized through pins or tenons; the die cores and the mud cores are positioned in the cavities of the upper die, the lower die and the middle die; the sprue is fixed in the upper die; and the die cores are a plurality of removable middle dies cores, upper dies cores and lower die cores in a shape of a grooved belt pulley, each die core is made of a metal material, and the die cores utilize an integral structure or a split structure. The casting mould has the characteristics of simple structure, low cost, high durability of the die cores, good quality of casting pieces, high casting efficiency, wide adaptability and the like.

Description

technical field [0001] The invention relates to a casting mold, in particular to a special casting mold for a belt pulley. technical background [0002] Pulleys are mainly used for long-distance transmission of power, such as the output of diesel engine power, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, and some small horsepower motorcycle power transmission. Power transmission of presses, reducers, reducers, generators, cotton gins, agricultural machinery, etc. Pulleys belong to hub parts. Generally, for larger pulleys, the manufacturing process is casting, and the material is iron; for smaller pulleys, forging is used, and the material is steel. However, since there are deep belt grooves on the outer circumference of the pulley, whether it is casting or forging, it is generally pre-cast (forged) according to the requirements of the drawings to form a cylindrical blan...
