Description
Technical field
The utility model relates to a kind of abrasive disk and production technical field thereof, particularly relates to a kind of abrasive disk foundry goods and makes the abrasive disk casting pattern of this abrasive disk foundry goods.
Background technology
Abrasive disk is by rotarily driving abrasive material to metal material, or nonmetallic materials carry out a kind of instrument of flexible grinding or polishing, its duty is low speed rotation grinding work-piece under stress, self be also consumed simultaneously wearing and tearing, due to the requirement of grinding work-piece flatness and product percent of pass very high so abrasive disk requires very high from the uniformity index that weares and teares, and want proof pressure and temperature on the impact of abrasive disk dimensional accuracy.So hardness and metallographic parameter differ the smaller the better in abrasive disk working region.With abrasive disk, processing as the product such as sapphire panel, solar silicon wafers, electronic ceramics of the visual device such as mobile phone requires that Brinell hardness difference is within 10 HB.
At present, abrasive disk has become a kind of grinding tool using the widest in coated abrasive tool.Due to the development of national economy, add the production method of this product and technological equipment relatively than to be easier to and simple, so from city to rural area, middle-size and small-size production unit increases day by day, and its output also obviously increases year by year.
To the eye, abrasive disc structure is simple, easy to use, cheap, by users are welcome; But from serviceability, particularly cutting ability, security, durability, most domestic product, compared with world level, also also exists very large gap.
Present casting abrasive disk material is a lot, and wherein have grey cast-iron, alloy cast iron, spheroidal graphite cast-iron, steel alloy, stainless steel etc., casting technique has the multiple sand casting process such as resin sand, water-glass sand, iron precoated sand.But existing casting technique is difficult to meet these two quality index of casting flaw that impact must not be had to use in the working region that card Brinell hardness difference is less than 10HB, ultrasonic inspection need wear away the degree of depth of abrasive disk requirement.
Utility model content
The purpose of this utility model be to provide a kind of hardness evenly, good stability, excellent cutting performance, durable in use, high-quality abrasive disk foundry goods.
The technical scheme adopted for reaching the purpose of this utility model is: a kind of abrasive disk foundry goods, comprise abrasive disk main part, it is characterized in that, on abrasive disk main part, plane is designed to step shape, the inner circle of abrasive disk main part is provided with an insulation shelves slag ring, is provided with a Surgery therapy overflow collection slag ring at the cylindrical of abrasive disk main part, and uniform exhaust deslagging is excellent on the insulation overflow collection slag ring of the cylindrical of abrasive disk main part.
Another object of the present utility model is to provide a kind of abrasive disk casting pattern for making above-mentioned abrasive disk foundry goods, and reasonable in design, insulation, exhaust performance are good.The technical scheme that the utility model adopts for this reason is: a kind of abrasive disk casting pattern, comprise cope, upper sand mold, drag box, lower sand mold, upper sand mold and lower sand mold are at casting mold die joint gluing, sealing, it is characterized in that, sprue is offered at upper sand mold center, be provided with cup above sprue, the center of lower sand mold is provided with straight channel nest accordingly; Lower sand mold is provided with overflow dreg collecting slot, offers annular overflow and slag exhaust duct accordingly in the upper sand mold of overflow dreg collecting slot top position; Be provided with an annular shelves slag chute around sprue in upper sand mold, and be arranged with annular ingate outside annular shelves slag chute; Upper sand mold and abrasive disk foundry goods contact surface are designed to step; In upper sand mold on abrasive disk main part more than plane, thermal center district at least arranges a circle exhaust needle or exhaust sheet.
As further improvement of the utility model, the upper profile of upper sand mold is provided with one and exports with annular overflow and slag exhaust duct the collecting ring be connected.
As further improvement of the utility model, the area of described collecting ring is 1/3rd of abrasive disk foundry goods area.
The abrasive disk foundry goods that the utility model provides and the beneficial effect of abrasive disk casting pattern:
1) because abrasive disk foundry goods is all generally hollow structure, the utility model utilizes the hollow size of abrasive disk foundry goods as casting casting position, and molten metal evenly pours into the insulation shelves slag ring cast gate to abrasive disk foundry goods from annular ingate.
2) be provided with an insulation shelves slag ring in the inner circle of abrasive disk main part, be provided with a Surgery therapy overflow collection slag ring at the cylindrical of abrasive disk main part, insulation shelves slag ring and Surgery therapy overflow collection slag ring two insulating rings are while shelves, overflow and slag, ensure the cooling of abrasive disk temperature equalization, even to guarantee the hardness of abrasive disk.
3) on abrasive disk main part, plane is designed to step shape, adds while large modulus is beneficial to balanced cooling and improves deslagging ability, due to this abrasive disk foundry goods adopt non-riser technology design this to improve magnesium iron, cast iron also very large from feeding effect.
4) in the upper sand mold on abrasive disk main part more than plane, thermal center district at least arranges a circle exhaust needle or exhaust sheet, in order to exhaust deslagging and control area cooling velocity.
5) uniform exhaust deslagging rod on the insulation overflow collection slag ring of the cylindrical of abrasive disk main part.
6) on abrasive disk, profile arranges collecting ring, and the area of collecting ring is 1/3rd of abrasive disk foundry goods area, collects the overflow sluggish metal that exhaust deslagging rod is discharged, improves the resistance to deformation intensity of casting mold while deslagging insulation.
Abrasive disk casting pattern of the present utility model is applicable to the composite molding casting process such as Reform of Resin Sand Casting fabrication technique, water-glass sand casting technique and iron precoated sand fabrication technique, this abrasive disk casting pattern is used to make abrasive disk foundry goods, can greatly to improve the quality of products level, reduce post-processed cost and time, the abrasive disk that application the method makes, good product quality, qualification rate is high.The abrasive disk product using abrasive disk casting pattern of the present utility model to make can meet simultaneously card Brinell hardness difference be less than 10HB and ultrasonic inspection need wear away the degree of depth working region in impact must not be had to use these two quality index of casting flaw.
