Abstract
A die pin for deep pre-cast holes of die castings relates to the technical field of die casting, and solves the problem that air holes and shrinkage holes are easy to generate; through the cooperation setting of aluminium system sleeve pipe and support type round pin, the dark precast hole machining allowance of product is unilateral 0.5mm entirely, avoids the production of the gas pocket of processing hole, shrinkage cavity.
Description
Technical Field
The utility model relates to a die-casting technical field especially relates to a type round pin in dark precast hole of die casting.
Background
The oil filter shell has an oil passage with an inner diameter phi of 28mm and a depth of 300mm, and under the condition that the inner diameters of the whole oil passage after being processed are consistent, the design of the precast hole type pin is generally as follows: according to the unilateral draft angle of 0.5 degree, the diameter of the large end is phi 27mm, and the diameter of the small end at the position of 300mm deep is phi 21.76 mm. The single-side machining allowance of the small end is 3.12mm, and the defects of air holes and shrinkage cavities are easily generated.
Disclosure of Invention
In order to solve the problem, the utility model provides a die pin in deep precast hole of die casting provides a die pin in die-casting deep hole. In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a type round pin in deep precast hole of die casting, compresses tightly round pin and base including support type round pin, aluminium system sleeve pipe, aluminium system shutoff clamp plate, aluminium system, the base on be provided with the recess, the main aspects of support type round pin set up in the recess of base, aluminium system sleeve pipe cover establish in the outside of supporting the type round pin, aluminium system shutoff clamp plate set up on the little terminal surface of support type round pin, aluminium system compress tightly the round pin and be connected with aluminium system shutoff clamp plate, compress tightly aluminium system shutoff clamp plate, aluminium system shutoff clamp plate is with aluminium liquid isolated outside aluminium system sleeve pipe.
Further, the inner diameter of the aluminum sleeve is set to 22.5mm, the outer diameter of the aluminum sleeve is set to 27mm, and the length of the aluminum sleeve is set to 298 mm.
Further, the outer diameter of the large end of the support-type pin is set to 22mm, the outer diameter of the small end of the support-type pin is set to 21mm, and the length of the support-type pin is set to 298 mm.
Further, the groove depth was set to 0.5 mm.
Compared with the prior art, the utility model discloses following beneficial effect has: through the cooperation setting of aluminium system sleeve pipe and support type round pin, the dark precast hole machining allowance of product is unilateral 0.5mm entirely, avoids the production of the gas pocket of processing hole, shrinkage cavity.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
FIG. 1 is a schematic diagram of the explosion structure of the present invention;
in the drawings: 1. the device comprises a supporting pin, 2 an aluminum sleeve, 3 an aluminum plugging pressing plate, 4 an aluminum pressing pin, 5 and a base.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described with reference to fig. 1 and the specific embodiments.
As shown in the attached figure 1, the die-casting part deep pre-cast hole type pin comprises a supporting type pin 1, an aluminum sleeve 2, an aluminum blocking pressing plate 3, an aluminum pressing pin 4 and a base 5, wherein a groove is formed in the base, the large end of the supporting type pin 1 is arranged in the groove of the base 5, the aluminum sleeve 2 is sleeved on the outer side of the supporting type pin 1, the aluminum blocking pressing plate 3 is arranged on the small end face of the supporting type pin 1, the aluminum pressing pin 4 is connected with the aluminum blocking pressing plate 3 to tightly press the aluminum blocking pressing plate 3, and the aluminum blocking pressing plate 3 is used for isolating aluminum liquid outside the aluminum sleeve 2.
Further, the inner diameter of the aluminum sleeve 2 is set to 22.5mm, the outer diameter of the aluminum sleeve 2 is set to 27mm, and the length of the aluminum sleeve 2 is set to 298 mm.
Further, the outer diameter of the large end of the support type pin 1 is set to 22mm, the outer diameter of the small end of the support type pin 1 is set to 21mm, and the length of the support type pin 1 is set to 298 mm.
Further, the groove depth was set to 0.5 mm.
The utility model discloses a theory of operation and working process as follows: the supporting pins 1 are matched with the aluminum pressing pins 4 through the aluminum plugging pressing plates 3 to fix the aluminum sleeves 2, so that the sleeves are prevented from being inclined in the aluminum liquid filling process, and the grooves of the base 5 can prevent aluminum liquid from entering the inside; the fit clearance between the support type pin 1 and the aluminum sleeve 2 is 0.25mm on one side, and a counter bore with a draft angle is formed in the small end face of the support type pin 1, so that the aluminum compression pin 4 can be conveniently inserted; when the die is opened, the supporting pin 1 is separated from the aluminum compression pin 4 and extends out of the product, the aluminum sleeve 2 remains in the product and serves as a precast hole, and the aluminum sleeve is eliminated in subsequent processing.
Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
