Background

In recent years, in order to meet the heat dissipation requirements of the engine of an automobile, the related parts of the engine need to be continuously improved, and the exhaust system of the engine also needs to be continuously improved, particularly the heat dissipation performance of an exhaust pipe. The butterfly valve is with regard to a fine reinforcing phase, but because the part of butterfly valve is less, especially in the preparation of extensive big product, extravagant serious according to traditional handicraft, the whole mould is heavy to be held up, and the yield is low, and how to improve butterfly valve production efficiency comparatively conveniently is the problem that needs the solution now urgently, provides a novel butterfly valve casting structure for this moment.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem in the prior art and providing a novel butterfly valve casting structure.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a novel butterfly valve casting structure, includes the butterfly valve body, pours the runner and pours the bush and constitute, it is vertical setting to pour the runner, just the butterfly valve body is a plurality of evenly distributed in the both sides of pouring the runner, it is including pouring mould and connection end mould to pour the runner, it comprises rectangle die cavity and connection runner to pour the mould, the connection end mould with pour the runner top intercommunication, and with be connected the runner and be linked together.

Preferably, the pouring mould channel consists of a cut-off end and a branch end, and the cut-off end and the branch end are arranged in a staggered mode.

Preferably, both sides of the branch flow end are provided with cut-off shunt tubes, and the other ends of the cut-off shunt tubes are communicated with the butterfly valve body.

Preferably, the rectangular die cavity is arranged in a rectangular shape and located in the middle, and the connecting die channels are arranged on two sides of the rectangular die cavity and arranged oppositely.

Preferably, the two connecting end dies on one side of the connecting die cavity are connected through a U-shaped overflow template.

Compared with the prior art, the beneficial effects of the utility model are that:

1. by adopting the scheme to pour the butterfly valve, the design is simple, the use is convenient, the static pressure of iron liquid and the effective feeding distance of a riser are effectively improved, a casting with compact structure is obtained, and the quality of the casting is improved;

2. the production efficiency is improved by 150%, the casting cost is saved by 20%, the yield is improved to 70%, the qualification rate is improved by 99%, and the large-scale production is facilitated.

Drawings

Fig. 1 is a schematic view of a main structure of a novel butterfly valve casting structure provided by the present invention;

fig. 2 is a schematic cross-sectional structure view of a novel butterfly valve casting structure provided by the present invention;

fig. 3 is a schematic view of a casting mold in the prior art.

In the figure: the method comprises the following steps of 1 butterfly valve body, 2 pouring mould channels, 21 cutoff ends, 22 branch ends, 3 pouring mouth molds, 31 rectangular mould grooves, 32 connecting mould channels, 33 connecting end molds, 4 cutoff branch pipes and 5 overflow templates.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Referring to fig. 1-3, a novel butterfly valve casting structure comprises a butterfly valve body 1, a casting mold channel 2 and a casting mold 3, wherein the casting mold channel 2 is vertically arranged, further, the casting mold channel 2 comprises a cut-off end 21 and a branch end 22, the cut-off end 21 and the branch end 22 are arranged in a staggered manner, cut-off flow distribution pipes 4 are arranged on two sides of the branch end 22, and the other ends of the cut-off flow distribution pipes 4 are communicated with the butterfly valve body 1;

the further advantage of the adoption of the structure is that the cut-off end 21 and the cut-off shunt pipe 4 can be used for easily breaking each part after pouring and forming, wherein the structure is narrow in the middle and can be broken from the middle when being stressed, so that the quality of the butterfly valve mold is ensured.

And butterfly valve body 1 is a plurality of evenly distributed in the both sides of pouring die way 2, it is including pouring mould and connection end mould 33 to pour bush 3, it comprises rectangle die cavity 31 and connection die cavity 32 to pour the mould, connection end mould 33 with pour 2 tops of die cavity and communicate, and be linked together with connecting die cavity 32, rectangle die cavity 31 is the rectangle setting, and be located the intermediate position, it just is relative the setting in rectangle die cavity 31 both sides to connect the die cavity 32 setting, it connects through the overflow template 5 that is the U type to be located between two connection end moulds 33 of connecting die cavity one side.

It is worth noting that as shown in fig. 3, which is a schematic diagram of a pouring mold in the prior art, a pouring mode for a butterfly valve is produced by using 200 × 200mm small molds, 4 pieces of the butterfly valve are placed in each mold, the molds can be stacked together for pouring after the butterfly valve is manufactured, the butterfly valve can be as high as possible, the butterfly valve is most economical when the butterfly valve is stacked to 10 layers through continuous tests, the product rejection rate is increased due to the fact that the butterfly valve is over 10 layers, and the efficiency is reduced when the butterfly valve is less than 10 layers. When 10 layers are accumulated, the weight of each box can reach 15kg, the pouring quantity is 40pcs, the mold closing time is long, the operation is complex, and the risk of box expansion and scrap exists.

Adopt this scheme to adopt 16 productions, back-to-back scheme, pour 32, pour weight 12kg, model size 450 x 550 mm. The efficiency is greatly improved and saved by 150%;

the static pressure feeding device has the advantages that the design is simple, the use is convenient, the static pressure of iron liquid and the effective feeding distance of a riser are effectively improved, and a casting with compact structure is obtained; the production efficiency is improved by 150 percent, the casting cost is saved by 20 percent, the yield is improved to 70 percent, the qualification rate is improved by 99 percent, and the method is favorable for large-scale production

The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
