Abstract
The utility model discloses a die used for producing the outer core of a damper of an automobile. The die mainly comprises an inner die and an outer die, wherein a plurality of pin shafts are arranged on the inner die; the pin shafts are matched with a plurality of pin holes arranged on the outer die; a plurality of diverter holes are uniformly opened on the inner die; the diverter holes are respectively communicated with welded rooms arranged on the outer die; the welded rooms are communicated with die holes arranged on the outer die; inner cores matched with the die holes are arranged on the inner die; and flow choked blocks are arranged on the inner wall of the welded rooms around the die holes. The utility model has the advantages that the die used for producing the outer core of the damper of the automobile can fully stir aluminium alloy melts existing in the welded rooms, so that the bonding force of the aluminium alloy melts going into the welded rooms from different diverted rooms is increased obviously, the welded seam of the produced tube blanks becomes small, and cracks are not easy to be generated when in flange processing, thereby improving the qualification rate of products and greatly reducing the production cost.
Description
Technical field
The utility model relates to a kind of mould that is used to make outer core of automotive shock absorber.
Background technology
The existing mould that is used to make outer core of automotive shock absorber, mainly comprise: internal mold and external mold, some bearing pins are set on internal mold, bearing pin cooperatively interacts with the some pin-and-holes that are arranged on the external mold, on internal mold, evenly offer some tap holes, tap hole is interconnected with the seam chamber that is opened on the external mold respectively, the seam chamber again be opened in external mold on nib communicate, internal mold is provided with the inner core that cooperatively interacts with nib.The mould shortcoming that being used to of this structure made outer core of automotive shock absorber is: can not the aluminium alloy melt that enter the seam chamber fully be stirred, make produced pipe seam seam bigger, add at flange and to be easy to generate the crack man-hour, the qualification rate of product is lower, and production cost is higher.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and can carry out the well-beaten mould that is used to make outer core of automotive shock absorber to the aluminium alloy melt that enters the seam chamber.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the mould that is used to make outer core of automotive shock absorber, mainly comprise: internal mold and external mold, some bearing pins are set on internal mold, bearing pin cooperatively interacts with the some pin-and-holes that are arranged on the external mold, on internal mold, evenly offer some tap holes, tap hole is interconnected with the seam chamber that is opened on the external mold respectively, the seam chamber again be opened in external mold on nib communicate, internal mold is provided with the inner core that cooperatively interacts with nib, and the inwall of the seam chamber around the described nib is provided with choker bar.
In order to solve the problems of the technologies described above better, the further technical scheme of the utility model is: evenly offer four tap holes on described internal mold altogether.
In order to solve the problems of the technologies described above better, the further technical scheme of the utility model is: be provided with four bearing pins on described internal mold altogether, four bearing pins cooperatively interact with four pin-and-holes that are arranged on the external mold respectively.
The utility model has the advantages that: this mould that is used to make outer core of automotive shock absorber can fully stir the aluminium alloy melt that enters the seam chamber, make and enter the indoor aluminium alloy melt adhesion of seam from different tap holes and obviously strengthen, produced pipe seam seam is diminished, add at flange and to be not easy to produce the crack man-hour, improve the qualification rate of product, greatly reduced production cost.

The specific embodiment
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, be used to make the mould of outer core of automotive shock absorber, mainly comprise: internal mold 1 and external mold 2, some bearing pins 3 are set on internal mold 1, bearing pin 3 cooperatively interacts with the some pin-and-holes 4 that are arranged on the external mold 2, on internal mold 1, evenly offer some tap holes 5, tap hole 5 is interconnected with the seam chamber 6 that is opened on the external mold 2 respectively, seam chamber 6 again be opened in external mold 2 on nib 7 communicate, internal mold 1 is provided with the inner core 8 that cooperatively interacts with nib 7, and the inwall of the seam chamber 6 around the described nib 7 is provided with choker bar 9.
In the present embodiment, evenly offer four tap holes 5 altogether on described internal mold 1, when reality was used, the number of tap hole 5 can be provided with arbitrarily according to actual needs.Be provided with 3, four bearing pins 3 of four bearing pins altogether and cooperatively interact with four pin-and-holes 4 that are arranged on the external mold 2 respectively on described internal mold 1, when reality was used, bearing pin 3 can be provided with arbitrarily according to actual needs with the number of pin-and-hole 4.
The operation principle that being used for of said structure made the mould of outer core of automotive shock absorber is: aluminium alloy melt is transported to extruder from pot arch, by containing the ingot bucket aluminium alloy melt is transported in the tap hole 5 then, aluminium alloy melt enters in the seam chamber 6 that is interconnected with it respectively from four tap holes 5, the choker bar 9 that is arranged in the seam chamber 6 can fully stir the aluminium alloy melt that enters seam chamber 6, make and enter the indoor aluminium alloy melt adhesion of seam from different tap holes 5 and obviously strengthen, at last, aluminium alloy melt flows out in nib 7, obtains needed aluminium alloy pipe.
