Abstract
The utility model discloses a pressure equipment mould structure with vacuum import function in advance, including die casting, collection sediment package, interface channel, the one end of die casting is respectively through runner and material handle intercommunication, the other end of die casting passes through interface channel and collection sediment package intercommunication, interface channel is circular arc transition structure. The structure is suitable for circular ring products. The structure is generally applied to a mould matched with a vacuum-pumping system, and the angle of the joint of the slag collecting bag and a product is modified on the basis of the original vacuum-pumping slag collecting structure so as to achieve the function of leading in advance. The utility model discloses can effectively improve the qualification rate of product, improve collection sediment effect, reduce inside gas pocket of product and impurity.
Description
Technical Field
The utility model belongs to the pressure casting field relates to especially almag zinc pressure casting, the collection sediment and the exhaust structure of concretely relates to foundry goods.
Background
In the process of pressure casting of the aluminum-magnesium-zinc alloy, a channel at the joint of a water tail slag collecting bag and a product of a circular ring product is generally connected at right angle (as shown in figure 3), and molten metal is directly formed by opposite punching and enters the slag collecting bag at last. The slag collection bag does not achieve a good slag collection effect, and gas and slag inclusion in the aluminum liquid are left in the product, so that the product has more air holes and hard points and the product qualification rate is lower. Lower product yields not only increase the cost of die casting but also the cost of post processing, (machine scrap and damage to tooling).
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at solving the deficiencies in the prior art, provide a pressure equipment mould structure with vacuum import function in advance, this structure can improve the collection sediment effect of ring class die casting collection sediment package, reduces defective rate such as gas pocket, clamp sediment.
The technical scheme is as follows: a pressure equipment mould structure with vacuum import function in advance, including die casting, collection cinder ladle, interface channel, runner and material handle, the one end of die casting communicates with the material handle through the runner respectively, the other end of die casting passes through interface channel and collection cinder ladle intercommunication, interface channel is circular arc transition structure.
Further, the die casting is a circular ring type die casting.
Furthermore, the connecting channel is made of a die-casting die steel insert with the hardness of HRC46-48 after heat treatment.
Furthermore, the chamfer radius of the circular arc transition of the connecting channel is 3-7 mm.
has the advantages that: the utility model relates to a pressure equipment mould structure with vacuum imports function in advance can effectual improvement collection sediment effect of collection sediment package, reduces the defective rate such as gas pocket, clamp sediment.

FIG. 2 is a schematic view of the slag collecting process in the mold production process of the present invention;
Fig. 3 is a schematic diagram of a mold structure in the prior art.
Detailed Description
The technical solution of the present invention will be further described in detail with reference to the following specific examples.
The press fitting die structure with the vacuum advanced introducing function as shown in fig. 1 comprises a die casting 1, a slag collecting bag 2, a connecting channel 3, a flow channel 4 and a material handle 5, wherein one end of the die casting 1 is respectively communicated with the material handle 5 through the flow channel 4, the other end of the die casting 1 is communicated with the slag collecting bag 2 through the connecting channel 3, and the connecting channel 3 is of an arc transition structure.
In the present embodiment, the die cast 1 is a circular ring die cast.
In this embodiment, the connecting channel 3 is made of a die-casting die steel insert with the hardness of HRC46-48 after heat treatment.
In the embodiment, the radius of the chamfer of the arc transition of the connecting channel 3 is 3-7MM, so that the cold materials and gas are guided into the slag collecting bag 6-10MM ahead of time, and the defects of product air holes, cold shut and the like are reduced.
The mold structure is generally applied to a mold matched with a vacuum-pumping system, and the angle of the joint of a slag collection bag and a product is modified on the basis of the original vacuum-pumping slag collection structure so as to achieve the function of leading in advance, as shown in fig. 2.
The utility model discloses can effectively improve the qualification rate of product, improve collection sediment effect, reduce inside gas pocket of product and impurity.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and although the present invention has been disclosed with the preferred embodiments, it is not limited to the present invention, and any skilled person in the art can make some modifications or equivalent embodiments without departing from the scope of the present invention, but all the technical matters of the present invention are within the scope of the present invention.
