Description

Be used for as cast special mould of regulating ring

Technical Field

The utility model relates to the technical field of mold, specifically be a special mould for regulating ring casting.

Background

Pouring liquid metal into a casting cavity which is adaptive to the existing shape of the part during casting, and cooling and solidifying the liquid metal to obtain the part or a casting. The casting material is usually a metal (e.g., copper, iron, zinc, aluminum, etc.) that forms a liquid by heating, and the material of the mold may be sand, metal, or even ceramic. The casting has the advantage of being convenient for producing parts with complex shapes, particularly castings with complex inner cavities, so the casting is widely used. The adjusting ring is a circular ring-shaped component, a plurality of grooves are annularly distributed on the inner ring of the adjusting ring, the structure is troublesome, and therefore, the adjusting ring can be manufactured in a mode of casting the die body in order to facilitate manufacturing.

The special mould of current control collar casting is only a simple mould, the middle part is equipped with the molding chamber, when casting the mould, the metal liquid after directly will melting is poured into the molding chamber, then treat it and take out it after cooling, but the metal liquid is when pouring full the molding chamber, because the power that exists between the liquid molecule, make the top of metal liquid not the horizontal plane, but there is the high condition low all around in middle part, make and need spend a large amount of time to polish the control collar foundry goods after the control collar casting is accomplished, make the top be the horizontality with the bottom equally, thereby it is troublesome to have brought some unnecessary for the production of control collar, the waste in time has been caused, lead to casting efficiency to reduce.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a special mold for casting an adjusting ring comprises a mold body 1, a molding cavity 9 is formed in the middle of the mold body 1, a pressing plate 4 is fixedly connected to the top of the mold body 1, fixing holes 11 are formed in the front and rear ends of the left and right sides of the top of the pressing plate 4, a limiting post 2 is fixedly mounted at the front and rear ends of the left and right sides of the top of the mold body 1, the position of the pressing plate 4 is limited by the limiting post 2, so that the phenomenon that scratches or shape distortion occurs on the surface of a cast product due to deviation of the pressing plate 4 in the cooling process of the cast product is prevented, thereby causing casting failure of the cast product, the fixing holes 11 are fixedly sleeved with the limiting post 2, a first threaded hole 10 is formed in the middle of the top of the pressing plate 4, a second threaded hole 8 is formed in the middle of the top of the mold body, the top of the outer side surface of the screw rod 6 is fixedly connected with a thread block 5.

Wherein, the preceding side at clamp plate 4 top is seted up and is located the notes material hole 3 that becomes die cavity 9 top, through being connected between clamp plate 4 and the mould body 1 for can't be to the inside metallic liquid that pours into of become die cavity 9 into, consequently seted up and be located the notes material hole 3 directly over becoming die cavity 9, feasible can be through annotating the inside injection metallic liquid of 3 case die cavity 9 in material hole, thereby guaranteed the normal casting of control ring.

Wherein, exhaust hole 7 has been seted up to the back side at clamp plate 4 top, there is a certain amount of gas in the inside of one-tenth die cavity 9, when injecting metal liquid into one-tenth die cavity 9 inside, because gaseous existence, can make metal liquid can't be full of one-tenth die cavity 9 completely, thereby lead to the foundry goods surface after the shaping or inside to have the bubble, thereby make the foundry goods quality can't reach the requirement, lead to the foundry goods failure, and exhaust hole 7 is seted up at the rear end at clamp plate 4 top, when injecting metal liquid, under metal liquid's extrusion, gas can be followed exhaust hole 7 and discharged, thereby the metal liquid that makes can be full of one-tenth die cavity 9 inside completely, make the inside of one-tenth die cavity 9 not have the air, thereby the phenomenon that the bubble can not appear on the foundry goods.

Wherein, screw thread direction of rotation on first screw hole 10 and the 8 medial surfaces of second screw hole is opposite, when screw 6 rotates, because first screw hole 10 is opposite with the inside screw thread direction of second screw hole 8, make clamp plate 4 and mould body 1 move towards opposite direction, thereby it is fixed to conveniently compress tightly clamp plate 4 and mould body 1, and simultaneously, the condition that clamp plate 4 and mould body 1 are difficult to part can appear after the foundry goods shaping, also can be through rotating screw 6 this moment, make clamp plate 4 and mould body 1 move to opposite direction, thereby pull open clamp plate 4 and mould body 1.

Wherein, the shape of fixed orifices 11 and spacing post 2 is circular, the circular diameter of fixed orifices 11 is greater than the circular diameter of spacing post 2, the circular diameter of fixed orifices 11 is slightly more than the circular diameter of spacing post 2, the circular diameter of fixed orifices 11 is if too big, can lead to the insecure connection between clamp plate 4 and the mould body 1, carrying out the cast in-process, clamp plate 4 takes place the skew, the contact site shape that leads to inside foundry goods top and clamp plate 4 changes, thereby lead to the foundry goods that the casting formed can't reach the requirement of production, thereby lead the foundry goods to scrap, cause the waste.

The working principle is as follows:

during the use, cup joint with spacing post 2 through fixed orifices 11, make clamp plate 4 be connected with mould body 1, then rotate screw rod 6, make clamp plate 4 and mould body 1 be close to each other, thereby make the connection between clamp plate 4 and the mould body 1 more inseparable, then through the inside injection metal liquid of 3 case molding cavities 9 in notes material hole, the inside gas of molding cavity 9 is discharged from exhaust hole 7 under the extrusion of metal liquid, after inside metal liquid is filled, stop to pour into, then wait for the metal liquid cooling to solidify, after the cooling is solidified, it makes clamp plate 4 and mould body 1 move to the direction of separation to rotate screw rod 6, until screw rod 6 withdraws from second screw hole 8 is inside, then take out the foundry goods, accomplish the casting.
