Abstract
The invention discloses a gear casting mold, which comprises a cylindrical cast seat, a toothlike casting and a gear reducer casting mold, wherein a cylindrical groove is formed in the central axis of the cylindrical cast seat; a convex cylinder is arranged in the cylindrical groove; the cylindrical groove is a stepped hole; the toothlike casting is an inner gear ring casting mold; the gear reducer casting mold is annular; teeth are arranged at two side end parts of the gear reducer casting mold; teeth at one side surface are completely meshed with inner wall teeth of the toothlike casting; teeth at the other side surface are different from the toothlike casting in dimension and shape. By virtue of the technical scheme, a reference dimension gear can be cast through the cylindrical groove in the cylindrical cast seat, the convex cylinder and the toothlike casting; if the tooth shape of the gear and the gear dimension need to be changed, only the proper gear reducer casting mold needs to be put on the inner tooth surface of the toothlike casting; one end of the gear reducer casting mold is completely meshed with the toothlike casting; and the needed toothlike casting is arranged at the other end of the gear reducer casting mold, so that another gear can be directly cast, and further waste of the cast mold is avoided.
Description
Technical field
The present invention relates to a kind of gear casting mould.
Background technology
Existing Gear Processing mode is generally machining, for the gear that required precision is higher, another kind of by casting directly casting, for the gear that relative accuracy is lower, or first cast machining again, the mode of casting is applicable to volume production, but a kind of gear is only arranged to by the mold of casting, if change cast gear just to need to change mold, cause the unnecessary wasting of resources like this.
Summary of the invention
The present invention is directed to above-mentioned technical problem, propose a kind of gear casting mould being suitable for multiple profile of tooth and gear diameter.
For reaching above object, be achieved through the following technical solutions:
A kind of gear casting mould, comprises, cylinder sprue base and profile of tooth foundry goods;
Cylinder sprue base axial centerline is cylindrical grooves, and cylindrical grooves axial centerline is provided with protruding column;
Cylindrical grooves is shoulder hole, and upper diameter is greater than lower diameter;
Profile of tooth foundry goods is ring gear mold, and namely profile of tooth foundry goods is annulus and inwall is provided with tooth; Profile of tooth foundry goods is embedded by screw thread and is assemblied in cylindrical grooves top, and lower surface and upper surface, cylindrical grooves ladder place near;
Also comprise gear reducing casting mould; Gear reducing casting mould is circular, and two side ends is all tooth, and a side tooth engages completely with profile of tooth cast inner wall tooth, the tooth that sized by opposite side tooth, shape is different from profile of tooth foundry goods;
Adopt the present invention of technique scheme, the gear of reference dimension can be cast by the cylindrical grooves in intrinsic cylinder sprue base, protruding column and profile of tooth foundry goods, if need tooth-formation of gear and gear size to change, only need to place an applicable gear reducing casting mould at profile of tooth foundry goods inner toothed surface, it is the profile of tooth mold needed that gear reducing casting mould one end and profile of tooth foundry goods engage the other end completely, so just can directly cast another kind of gear, and then avoid the waste of mold.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to technological means of the present invention can be better understood, and can be implemented according to the content of description, and can become apparent to allow above and other object of the present invention, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
The present invention is totally 1 width accompanying drawing, wherein:
Fig. 1 is plan structure schematic diagram of the present invention.
Detailed description of the invention
A kind of gear casting mould as shown in Figure 1, comprises, cylinder sprue base 1 and profile of tooth foundry goods 2;
Cylinder sprue base 1 axial centerline is cylindrical grooves 3, and cylindrical grooves 3 axial centerline is provided with protruding column 4;
Cylindrical grooves 3 is shoulder hole, and upper diameter is greater than lower diameter;
Profile of tooth foundry goods 2 is ring gear mold, and namely profile of tooth foundry goods 2 is for annulus and inwall is provided with tooth; Profile of tooth foundry goods 2 is embedded by screw thread and is assemblied in cylindrical grooves 3 top, and lower surface and upper surface, cylindrical grooves 3 ladder place near;
Also comprise gear reducing casting mould 5; Gear reducing casting mould 5 is circular, and two side ends is all tooth, and a side tooth engages completely with parietal tooth in profile of tooth foundry goods 2, the tooth that sized by opposite side tooth, shape is different from profile of tooth foundry goods 2;
Adopt the present invention of technique scheme, the gear of reference dimension can be cast by the cylindrical grooves 3 in intrinsic cylinder sprue base 1, protruding column 4 and profile of tooth foundry goods 2, if need tooth-formation of gear and gear size to change, only need to place an applicable gear reducing casting mould 5 at profile of tooth foundry goods 2 inner toothed surface, it is the profile of tooth mold needed that gear reducing casting mould 5 one end and profile of tooth foundry goods 2 engage the other end completely, so just can directly cast another kind of gear, and then avoid the waste of mold.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art are not departing within the scope of technical solution of the present invention, when the technology contents that appeal can be utilized to disclose is made a little change or is modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
