Abstract
The utility model discloses a mould air exhausting device. The mould air exhausting device is characterized in that an air exhausting plugging hole is drilled on the top of a top core rod in a certain depth, then, a hole which is drilled on the side surface of the top core rod is communicated with the air exhausting plugging hole through calculating the vertical distance H between the upper end surface of the top core rod and the core box emptying position, wherein the distance between the upper end surface of the top core rod and the side surface of the top core rod is larger than H, so that the gas is discharged outside a mould; and the core box id provided with an air channel, the air exhausting plugging hole is formed in an air exhausting plugging top core, the side edge of the air exhausting plugging hole is provided with a via hole, and the air exhausting plugging hole is communicated with the via hole and the air channel. The device provided by the utility model has the advantages that the structure is simple, the space usage is small, the device is convenient and practical, the presupposed air exhausting effect is achieved, meanwhile, the mould is greatly convenient to change, and the production efficiency is improved.
Description
Technical field
The utility model relates to the layout of plunger tip pole pair venting plug under utilizing on the mould.
Background technology
The good influence that is subjected to penetrating exhaust effect in the sand process to a great extent with difference of castability, the smooth and easy sand of will penetrating of exhaust is abundant, penetrates discontentedly otherwise then can cause, and produces defective work.Existing a lot of casting mould, particularly those there is the more complicated die cavity as cylinder cap main body core, owing to lack enough spaces, can't be in narrow groove position, dark position, chamber etc. carries out the setting of exhaust apparatus, directly caused the failure of casting, the shape of product size that casting is come out is inaccurate, has had a strong impact on the product accuracy, simultaneously, follow-up doing over again also brought the raising of production cost, the problems such as prolongation of production cycle.
In addition, venting plug is generally arranged substantially, do not have the coordinate of venting plug on the X-Y scheme of mould, and three-dimensional modeling is not made venting plug yet, and the disappearance of coordinate dimension might be given and changed mould and bring certain trouble, to have the technology of inlaying more very.If the change position interferes with venting plug (hole), previous soldering or the car plug of must increasing such as blocks at operation, and workload is increased greatly.
Summary of the invention
At the deficiencies in the prior art, the utility model provide a kind of under utilizing on the mould method of plunger tip bar arranging exhaust air plug, promptly bore the exhaust consent of certain depth at plunger tip masthead end, empty the vertical range H of position by calculating plunger tip bar upper surface and core box then, bore a via on down greater than the side of H distance and communicate with it in that the plunger tip bar is straight by the upper surface, gas is discharged from outside the mould.Simple and practical, convenient and reliable.
Technical solution of the present utility model is such, a kind of die venting device, it is characterized in that plunger tip masthead end bores the exhaust consent (1) of certain depth, empty the vertical range H of position then by plunger tip bar upper surface and core box, bore a via (2) on down greater than the side of H distance and communicate with it in that the plunger tip bar is straight by the upper surface, core box has air flue (4).
Air flue (4) communicates with exhaust consent (1), and via (2) communicates with outside air.
The utlity model has following advantage:
(1), in some narrow groove positions, dark position, chamber is difficult to the place of arranging exhaust air plug, can be by the venting plug near the plunger tip bar it, thus reach exhaust effect.
(2), adopt this method owing to saved the venting plug of unknown coordinates, and the coordinate of plunger tip bar is clear and definite, this just makes that changing die worker author knows what's what, and has well controlled whole technical process, has improved operating efficiency.
(3), more spaces have been discharged for mold cavity.
Description of drawings
Fig. 1 is the main cutaway view of looking of the utility model die venting Unit Installation assembling.
In the accompanying drawing, exhaust consent (1), via (2), plunger tip bar (3), air flue (4), plunger tip bar upper surface to the minimum position H that empties an end face, via diameter D, plunger tip bar upper surface to the distance L of side via.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.Core box has air flue (4) and bores a vertical exhaust consent (1) on the top of plunger tip bar, bores a via (2) in exhaust consent (1) bottom outlet bottom side, and vertical mutually.Plunger tip bar (3) is installed in the groove position of exhaust consent (1).Air flue (4) communicates with exhaust consent (1), communicates with via (2), and via (2) communicates with outside air.
As figure, H is plunger tip bar upper surface and the minimum range of emptying an end face, and D is the diameter of plunger tip bar side via (2), and L then is the vertical range of plunger tip bar upper surface to the side through hole.Arrange the plunger tip bar groove position that has venting plug as required, calculate the pit bottom surface to the current minimum range of emptying an end face, after the through-hole diameter size of the selected side of plunger tip shank diameter, draw the L value, boring, counterbore after being finished jointly by pincers worker and driller are finally squeezed into venting plug again.(note: the position of emptying of some foundry goods belongs to non-machined surface, and emptying bit depth may not be inconsistent with the figure paper size, concrete man of Foundry Works regulation with reference to butt joint, suggestion is still to field measurement)
Present technique will be carried out careful calculating to the drilling depth of plunger tip bar, to guarantee that gas can be discharged to outside the mould.The selection of plunger tip bar material, the size of top end diameter also will be analyzed, and also can influence the function that the plunger tip bar originally has as liftout attachment because boring makes that wall is too thin.And on the sidewall face of cylinder, hole, driller has also been proposed requirements at the higher level.
More than disclosed only be a concrete example of implementing of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
Claims (2)
1. die venting device, it is characterized in that plunger tip masthead end bores the exhaust consent (1) of certain depth, empty the vertical range H of position then by plunger tip bar upper surface and core box, bore a via (2) on down greater than the side of H distance and communicate with it in that the plunger tip bar is straight by the upper surface, core box has air flue (4).
2. according to the described a kind of die venting device of claim 1, it is characterized in that air flue (4) communicates with exhaust consent (1), via (2) communicates with outside air.
