Abstract
The utility model discloses a sand blocking riser for casting relates to sand blocking riser technical field, this sand blocking riser for casting, including sand blocking riser body, sand blocking riser body's inside is opened there is the gate, the inside of gate is provided with first lug and second lug, wherein, first lug is located the top of gate one side, the second lug is located the below of gate opposite side, first lug slope sets up towards the second lug, the second lug slope sets up towards the first lug, first lug and second lug compress into zigzag structure with the cavity of gate inside, under the separation effect of first lug, can make the molten metal directly get into in the sediment groove, and then carry out the deposit to the gravel that is mingled with in the molten metal; utilize the pushing off the slag cotton in the sediment groove, cooperate the through-hole simultaneously, inertia when utilizing the molten metal to pass the through-hole can tightly compress tightly the gravel on the pushing off the slag cotton to improve the cleanliness factor when the molten metal gets into the mould, avoid the foundry goods to press from both sides the sand.
Description
Technical Field
The utility model belongs to the technical field of keep off the sand rising head, specifically be a casting is with keeping off sand rising head.
Background
The sand blocking riser is used on a pouring cup, and the pouring cup is used as an important component of a casting system and is mainly used for receiving molten metal, preventing splashing and overflowing and facilitating casting; the direct impact of molten metal on the casting mold is reduced;
in chinese patent No. CN213530683U, a "reusable split type slag blocking pouring cup" is disclosed, in which "slag blocking cotton is inserted above the supporting baffle, two sides of the slag blocking cotton are fixed in the inclined rails, slag is poured down along with molten metal, and when contacting the slag blocking cotton, slag is adhered to the surface of the slag blocking cotton", but the above solution still has problems, for example, because the slag blocking cotton is inclined, when the molten metal is poured, the molten metal is influenced by gravity and the impact force when the metal is poured, and the impact force attached to the slag blocking cotton can still enter the mold through the pouring gate, so that the casting sand inclusion is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a casting is with keeping off sand rising head to the gravel that proposes in solving above-mentioned background art gets into the mould along with the molten metal, causes the problem of foundry goods sand inclusion.
The utility model adopts the technical scheme as follows:
the utility model provides a foundry sand blocking riser, includes the sand blocking riser body, the inside of sand blocking riser body is opened there is the runner mouth, the inside of runner mouth is provided with first lug and second lug, wherein, first lug is located the top of runner mouth one side, the second lug is located the below of runner mouth opposite side, first lug slope sets up towards the second lug, the second lug slope sets up towards first lug, first lug and second lug compress into the zigzag structure with the cavity of runner mouth inside.
Preferably, the first lug, the second lug and the sand blocking cap body are of an integrated structure.
Preferably, a slag settling groove is formed between the second bump and the inner wall of the sand stopper body.
Preferably, slag blocking cotton is arranged on one side, close to the second bump, inside the slag settling tank.
Preferably, a plurality of through holes are formed in the second bump, and the slag blocking cotton covers one side of each through hole.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
in the utility model, when in use, under the blocking action of the first lug, the molten metal can directly enter the slag settling tank after entering the gate opening, and then the gravel mixed with the molten metal is settled;
utilize the pushing off the sediment cotton in the sediment groove, can further adsorb the gravel and set up, cooperation through-hole simultaneously can make the molten metal directly pass the second lug, and inertia when utilizing the molten metal to pass the through-hole can tightly compress tightly the gravel on pushing off the sediment cotton to improve the cleanliness factor when molten metal gets into the mould, avoid the foundry goods to press from both sides the sand.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of the present invention;
in the figure: 1. a sand cap body; 2. a slag settling tank; 3. a gate opening; 4. a first bump; 5. a through hole; 6. a second bump; 7. and (5) slag stopping cotton.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1-2, a sand blocking riser for casting comprises a sand blocking riser body 1, wherein the sand blocking riser body 1 is a disposable product and disappears after the product is poured without being recycled, a pouring gate opening 3 is formed in the sand blocking riser body 1, a first bump 4 and a second bump 6 are arranged in the pouring gate opening 3, the first bump 4 is located above one side of the pouring gate opening 3, the second bump 6 is located below the other side of the pouring gate opening 3, the first bump 4 is obliquely arranged towards the second bump 6, the second bump 6 is obliquely arranged towards the first bump 4, and a cavity inside the pouring gate opening 3 is compressed into a zigzag structure by the first bump 4 and the second bump 6.
A sediment groove 2 is formed between the inner walls of the second convex block 6 and the sand blocking cap body 1, sediment cotton 7 is arranged on one side, close to the second convex block 6, of the inner portion of the sediment groove 2, a plurality of through holes 5 are formed in the inner portion of the second convex block 6, and the sediment cotton 7 covers one side of the through holes 5.
Through the technical scheme:
when the sand blocking cap is used, the molten metal is directly poured into the sand blocking cap body 1 through the sprue gate 3, and under the blocking action of the first bump 4, the molten metal firstly enters the slag settling groove 2 between the second bump 6 and the sand blocking cap body 1 when entering the sprue gate 3, so that gravel mixed in the molten metal is deposited;
utilize the pushing off the slag cotton 7 in the sediment groove 2, can further adsorb the gravel and fasten, cooperate simultaneously under the effect of through-hole 5, can make the molten metal directly pass second lug 6, utilize the inertia when the molten metal passes through-hole 5, can tightly compress tightly the gravel on pushing off the slag cotton 7 to improve the cleanliness factor when the molten metal gets into the mould, avoid the foundry goods to press from both sides the sand.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
