Description
Technical field
This utility model relates to a kind of arc core-pulling device for die.
Background technology
At present, in the actual production of enterprise, for various foundry goods, various casting mould can be designed.Complex-shaped due to foundry goods, when encountering the foundry goods with circular arc endoporus, being generally utilized in the method that in die cavity, loam core is placed in craft, this loam core is meltable loam core, in other words, casting at foundry goods also will by outside the loam core thawing outflow foundry goods in foundry goods circular hole after well.Therefore, there is following shortcoming in this arc core-pulling:
1) placing loam core due to manual in die cavity, the site error of placement is relatively big, and therefore, the casting dimension degree of accuracy of the circular arc endoporus after molding is low, even causes scrapping of whole foundry goods；
2) it addition, outflow is melted after completing in loam core by foundry goods again, being greatly prolonged the man-hour of production, therefore, production efficiency is very low.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of arc core-pulling device for die, this device is in use, pull bar is driven by straight slide block, circular arc slide block is pulled by pull bar, the demoulding of movable jack is completed by the movement of circular arc slide block, the smoothness of circular arc slide block can be increased by arranging roller, accelerate the demoulding time.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of arc core-pulling device for die, including the circular arc slide block being positioned at lower bolster die cavity, the lower surface of described circular arc slide block is provided with the movable inserted block coordinating foundry goods circular arc endoporus, it is combined with screw between described movable inserted block and described circular arc slide block, it is provided with straight runner in described lower bolster, straight slide block it is provided with in described straight runner, it is combined with pull bar between described straight slide block and described circular arc slide block, described pull bar respectively and is combined with bearing pin between described straight slide block and described circular arc slide block, described lower bolster has the circular arc slideway coordinating described circular arc slide block, plural roller on the lower surface of described circular arc slideway, it is combined with roller shaft between described roller and described lower bolster, described roller extends in described circular arc slideway, the lower surface of described circular arc slide block has the roller groove coordinating described roller.
Preferably, the cell wall of described straight runner is symmetrically arranged with the gathering sill of two circular arcs, the outer surface of described straight slide block is provided with the guide pad coordinating described gathering sill.
Preferably, described roller groove extends to described circular arc slide block that one end near described movable inserted block, and when described roller props up roller groove when that one end of movable inserted block, described movable inserted block departs from the circular arc endoporus of foundry goods.
Preferably, described circular arc slide block has jack, and described movable inserted block coordinates in described jack.
The beneficial effects of the utility model are: this device is in use, pull bar is driven by straight slide block, circular arc slide block is pulled by pull bar, the demoulding of movable jack is completed by the movement of circular arc slide block, can increasing the smoothness of circular arc slide block by arranging roller, accelerate the demoulding time, the structure of this device is relatively simple, cost is comparatively cheap, is suitable for promoting the use of.
