Description
Technical Field
The utility model belongs to the technical field of the casting mould, concretely relates to aluminum alloy verts casting mould for aluminum alloy foundry goods.
Background
On some aluminum alloy castings, because the product has an undercut structure in multiple directions, a plurality of side dies must be arranged along the demoulding direction of the side dies, some products have 1 side die, some products have a plurality of side dies, the side dies are generally arranged by considering the normal release of the concave structure of the products, but some products have thick bolt mounting hole bosses in the middle of the products, so when a pouring structure is normally arranged, the solidification sequence and feeding problems of the thick parts (thermal junctions) during solidification must be considered. If only partial stripping of the side die of the product is considered, and no riser and feeding channel are arranged from the side die, the internal structure of the thick part of the product is likely to have shrinkage porosity and cracking problems.
Disclosure of Invention
The utility model aims at overcoming the above-mentioned not enough of prior art, and provide an aluminum alloy casting mould that verts, have simple structure, product internal quality high, product quality is stable and the characteristics of product percent of pass height.
The technical solution of the utility model is that: the utility model provides an aluminum alloy verts casting mould, includes mould, lower mould and side form, its characterized in that: the side die comprises a side convex structure matched with an outer side concave structure of the product; and a side die riser is arranged on the side die.
The technical solution of the utility model in the side form on be equipped with side form spliced pole side form connecting plate.
The side mould in the technical proposal of the utility model also comprises a side mould connecting part matched with the product hot spot part; and a feeding channel is arranged between the connecting part of the side mould riser and the side mould.
The thickness of the side mould at the opening of the side mould is 15-20mm in the technical solution of the utility model.
The side form thickness of the side form riser in the technical solution of the utility model is 7-9 mm.
The technical solution of the utility model in the side form die thickness of side form riser department be 8 mm.
The technical solution of the utility model in the side form rising head be located the upper left side or the upper right side at side form connection position.
The technical solution of the utility model is that the upper die and the corresponding position of the product head are provided with a pouring basin or an aluminum water inlet.
The technical solution of the utility model is that the product thermal segment position is the product bolt mounting hole boss position.
The technical solution of the utility model is that the side form is one or more.
The utility model discloses on the basis of current aluminum alloy casting mould that verts, owing to be equipped with on the side form with the outside undercut structure complex side convex structure of product, and be equipped with the side form rising head, therefore during the pouring, set up the mould type and the ejecting technology of product from the lower mould about the product mainly adopts, the aluminium water pours into the runner basin into, 90 in-process of equipment upset backward, the aluminium water gets into the die cavity, and begin to solidify the shaping gradually, and simultaneously, the side form is full of by the aluminium water in the rising head, after the foundry goods "stands", the additional rising head of its side begins to mend the thick big thermal segment position of lower part in the product (the aluminium water in the rising head flows to this thermal segment). Because of the riser standing on the side edge when the product is solidified, the thick part of the product is fed, and the shrinkage defect inside the thick part of the casting is eliminated.
The utility model discloses the feeding at the thick big position of product foundry goods that the outside has the undercut structure of mainly used.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-3. The utility model relates to an embodiment of aluminum alloy casting mould that verts, for the aluminum alloy casting mould that verts of certain aluminum alloy casting product, including last mould, lower mould and side form 3, two outside directions of certain aluminum alloy casting product have the undercut structure, and side form 3 sets up between last mould and lower mould to cooperate with last mould and lower mould. The upper die and the lower die are respectively matched with the upper part and the lower part of an aluminum alloy casting product in shape and are the same as the upper die and the lower die of the existing die. The side die 3 is provided with a side die connecting column 2 and a side die connecting plate 1, so that the oil cylinder can be conveniently pulled. The side mold 3 comprises a side convex structure matched with an outer side concave structure of a product and is matched with the outer shape of an aluminum alloy casting product.
The side die 3 is provided with a side die riser 3-a and a side die connecting part 3-b matched with a product heat section part, and a feeding channel is arranged between the side die riser 3-a and the side die connecting part 3-b. The product hot spot position is the product bolt mounting hole boss position. The side die riser 3-a is positioned at the upper left of the side die connecting part 3-b, and when the side die riser 3-a is rotated by 90 degrees clockwise, the side die riser 3-a is positioned at the upper right of the side die connecting part 3-b. The thickness of the side die 3 at the side die riser 3-a is 6-12mm, preferably 7-9mm, and 8mm is selected in the embodiment. The upper die is provided with an aluminum water inlet at the position corresponding to the head of the product.
When the process design development of product, from the overall structure analysis of product, set up it into the pouring mode that verts, set up the water inlet of aluminium water from the product head, the mould filling's of aluminium water in the die cavity in-process, equipment overturns simultaneously, about 10 seconds, equipment upset 90 targets in place, and the aluminium water is full of the die cavity, begins to solidify, and about 3 minutes later, the aluminium water solidifies, the foundry goods shaping of certain aluminum alloy foundry goods product. Due to the existence of the side mould riser 3-a, the side mould 3 is firstly opened, the side mould 3 is pulled by the oil cylinder to be drawn out in place, and then the upper mould can be opened. If the upper die is opened first, the die cannot be opened. If the side die 3 is not opened in place, the die can drive the head of the side die 3 which is not completely removed to be tilted upwards, and the die can be damaged or pulled.
When the side die feeder 3-a is arranged, the peripheral wall thickness of the side die feeder 3-a must be well controlled and cannot be too thick, so that the temperature of the side die 3, particularly the side die feeder 3-a part cannot reach the requirement, and if the temperature of the side die feeder 3-a part is low, the side die feeder may be solidified before the thick part of the product, and the thick part of the product cannot be fed. In production, we set the wall thickness around the riser to about 8mm, combining factors such as riser and product structure, mold material, etc.
