Abstract
The utility model relates to the technical field of gear casting, and discloses a fixture method for performing sand-molding pouring on a half gear pressure box and a fixture pressure plate. The pressure plate comprises a pressure plate body and three hanging handles, wherein the pressure plate body has a semicircular plate type structure; one hanging handle is arranged in the center of the semicircular edge of the pressure plate body; and the other two hanging handles are respectively arranged on two sides of the semicircular edge of the pressure plate body. The problems that partial castings are subjected to shakeout, bump and misrun caused by non-uniformity of the pressure box are solved completely; the fixture has the characteristics of simple structure, practicability, convenience in manufacturing, low cost and the like; and an extremely good technical economic effect is achieved.
Description
[technical field]
The utility model relates to the gear casting technology field, relates in particular to a kind of half gear class foundry goods and uses platen.
[background technology]
At present, when half gear is pressed case, because half gear shape is special; Ectonexine foundry goods body and riser height be not on same, and distributing is fan-like pattern again, uses common foundary weight to press case to be difficult to effectively evenly distribution foundary weight weight; Making effective pressure conduct to all cover cores lifts in the case power effect scope; Often occur that case is lifted in the part, the part is damaged situation such as sand mold by pressure, gently then cause a large amount of repairing repair weldings, heavy then directly cause directly scrapping of whole foundry goods.
[summary of the invention]
In order to overcome the deficiency in the background technology; The utility model provides a kind of half gear class foundry goods to use platen; It is the frock of carrying out half tooth class castings production; Thoroughly solved because of pressing local casting falling sand, exoncoma, the misrun problem of the inhomogeneous formation of case, had characteristics such as simple in structure, practical, easy to make, with low cost.
In order to realize the foregoing invention purpose, the scheme that the utility model adopted is:
A kind of half gear class foundry goods is used platen; Comprise: platen body and three hang handle; Said platen body is arranged to semicircle shape ring disk-shaped structure, and the position at this external semi arch edge center of platen is provided with one and hangs handle, and two side positions of semi arch edge are respectively arranged with one and hang handle in the platen body.
A kind of half gear class foundry goods is used platen, is evenly distributed with several trapezium structure holes on the semicircle shape ring disk-shaped structure of said platen body.
A kind of half gear class foundry goods is used platen, and platen body and three hang being carbon steel material cast form structure.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
A kind of half gear class foundry goods is used platen, is the frock of carrying out half tooth class castings production, is the geomery according to half tooth class foundry goods, and design of series is used for the preceding special tooling of pressing case of sand mold cast.The utility model has thoroughly solved because of pressing local casting falling sand, exoncoma, the misrun problem of the inhomogeneous formation of case, and this kind frock has characteristics such as simple in structure, practical, easy to make, with low cost, has obtained fabulous techno-economic effect.
[description of drawings]
Fig. 1 is that half gear class foundry goods is used the platen structural representation;
Among the figure: 1, platen body; 2, hang handle; 3, trapezium structure hole.
[specific embodiment]
As shown in Figure 1; A kind of half gear class foundry goods is used platen; Comprise: platen body and three hang handle; Said platen body is arranged to semicircle shape ring disk-shaped structure, and the position at this external semi arch edge center of platen is provided with one and hangs handle, and two side positions of semi arch edge are respectively arranged with one and hang handle in the platen body.
Be evenly distributed with several trapezium structure holes on the semicircle shape ring disk-shaped structure of said platen body.Said platen body and three hang being carbon steel material cast form structure.
A kind of method for tooling that is used for the preceding half gear pressure of sand mold cast case, its step is following:
1), mould assembling finish the cast before platen is placed on the casting mold,
2), re-using common foundary weight is pressed on the platen; Foundary weight weight is evenly distributed on the whole profile; Realize that the local foundry goods of pressing case evenly to form does not have the defective of knockout, exoncoma, misrun, satisfy the gross weight of foundary weight and platen, guarantee that the pressure case of whole casting mold meets the requirements.
Claims (3)
