The content of the invention
For overcome the deficiencies in the prior art, the utility model provide a kind of internal helicoid water channel sand cores it is easy for installation, Position firm, precision is high, overall structure be simply to manufacture electric machine casing casting moulds.
Technical scheme is used by the utility model solves its technical problem:
A kind of casting moulds for being used to manufacture electric machine casing, include upper die and lower die, left side mould, right side mould and spiral water Road core, the die cavity to match with electric machine casing shape can be formed by merging the upper die and lower die, left side mould and right side mould, The spiral channel core be arranged on the die cavity in, the spiral channel core include to be formed spiral channel conveyor screw and Two positioning sliding blocks, the positioning sliding block is located on the outside of the electric machine casing after electric machine casing moulding by casting, the conveyor screw Each circle is provided with cylinder table and is connected on the positioning sliding block, on the position of corresponding two positioning sliding blocks of lower mould Two support locating dowels are provided with, the chute to be cooperated with the positioning sliding block is provided with the support locating dowel, it is described Chute extends upwardly to the upper end of the support locating dowel, and the positioning sliding block can freely up and down slide in the chute.
As the improvement of above-mentioned technical proposal, wherein a support locating dowel offers away from the side of the chute Air slot, the air slot connect with the chute, are opened up described in the left side mould and right side mould face on the position of air slot There is exhaust outlet.
Further, two positioning sliding blocks are symmetrical on the axis of screw of the conveyor screw.
Further, the lower end with the positioning sliding block of the air slot homonymy is provided with positioning convex;The positioning is slided When block is arranged on inside the chute, the positioning convex is located in the air slot.
Further, the support locating dowel is detachably arranged on the lower mould.
The beneficial effects of the utility model are:The utility model on the spiral channel core by setting the positioning Sliding block and the chute is set in the support locating dowel, and passes through the shape that the positioning sliding block and the chute cooperate Formula installs the spiral channel core;So only need the positioning sliding block sliding into the chute from the upper end of the chute Bottom can both complete the installation of the spiral channel core, therefore whole operation is simple and convenient, can largely improve The efficiency of mould assembling;And by the cooperation of the positioning sliding block and the chute, the spiral shell can be prevented with very effective Water channel sand cores rocking in mold cavity all directions is revolved, therefore also improves the positioning precision of the spiral channel core; It is connected to simultaneously because each circle of the conveyor screw is provided with cylinder table on the positioning sliding block, therefore the positioning sliding block Good booster action can also be played to the spiral channel core, so as to improve the fixing of installation positioning.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is overall structure diagram of the present utility model;
Fig. 2 is mounting structure schematic diagram of spiral channel core described in the utility model on the lower mould.
Embodiment
Reference picture 1, Fig. 2, a kind of casting moulds for being used to manufacture electric machine casing of the present utility model, include mould 1, lower mould 2nd, left side mould 3, right side mould 4 and spiral channel core 5, merging upper mould 1, lower mould 2, left side mould 3 and the right side mould 4 can be with The die cavity to match with electric machine casing shape is formed, the spiral channel core 5 is arranged in the die cavity, the spiral channel Core 5 includes the conveyor screw 51 to form spiral channel and two positioning sliding blocks 52, the positioning after electric machine casing moulding by casting Sliding block 52 is located on the outside of the electric machine casing, and each circle of the conveyor screw 51 is provided with cylinder table and is connected to the positioning cunning On block 52, two support locating dowels 21, the support are provided with the position of corresponding two positioning sliding blocks 52 of lower mould 2 The chute 211 to be cooperated with the positioning sliding block 52 is provided with locating dowel 21, the chute 211 extends upwardly to the branch The upper end of locating dowel 21 is supportted, the positioning sliding block 52 can freely up and down slide in the chute 211.The utility model by The positioning sliding block 52 is set on the spiral channel core 5 and the chute 211 is set in the support locating dowel 21, and The spiral channel core 5 is installed by the positioning sliding block 52 and the form of the mutual cooperation of the chute 211;So only need The positioning sliding block 52 is slided into the bottom of chute 211 from the upper end of the chute 211 can both complete the spiral channel The installation of core 5, therefore whole operation is simple and convenient, can largely improve the efficiency of mould assembling;And pass through The cooperation of the positioning sliding block 52 and the chute 211, it can prevent the spiral channel core 5 in die cavity with very effective Rocking in portion's all directions, therefore also improve the positioning precision of the spiral channel core 5;Simultaneously because the conveyor screw 51 each circle is provided with cylinder table and is connected on the positioning sliding block 52, therefore the positioning sliding block 52 can also be to described Spiral channel core 5 plays good booster action, so as to improve the fixing of installation positioning.
Substantial amounts of gas will be produced in cast, gas is discharged for convenience, improves the quality of electric machine casing, wherein A piece support locating dowel 21 offers air slot 212 away from the side of the chute 211, the air slot 212 with it is described Chute 211 is connected, and exhaust outlet is offered on the position of air slot 212 described in left side mould 3 and right side mould 4 face.
Preferably support is provided the spiral channel core 5 for convenience and positioning, two positioning sliding blocks 52 close It is symmetrical in the axis of screw of the conveyor screw 51.While in order to prevent from filling when installing the spiral channel core 5 The problem of anti-, Anti-error structure is specially provided with the present embodiment, in the positioning sliding block 52 with the homonymy of air slot 212 Lower end be provided with positioning convex 521;When the positioning sliding block 52 is arranged on 211 inside of chute, the positioning convex 521 In the air slot 212.So in the case where the spiral channel core 5 have rotated 180 °, the spiral channel sand Core 5 will be unable to be installed in the support locating dowel 21.
