Abstract
The utility model relates to a metallic casting mould for ball grinding, which is exclusively used for casting grinding balls used by various ball grinders. A horizontally typing type is adopted by the utility model, a sand core running channel is adopted by the utility model, and multiple castings can be realized by the utility model. The casting quality of grinding balls can be realized, the performance properties of grinding balls can be enhanced, hi-chrome cast iron for grinding balls produced by the utility model, a high heat treatment process can be omitted, the grinding balls can be directly produced in a cast condition, the operating requirements of big, medium, and small cement mills can be met, and the utility model has the advantages of no broken balls and no deformation. The ball consumption rate can be cut down to less than 50 g/ ton (cement).
Description
The utility model relates to a kind of permanent mold casting mould of abrading-ball, particularly relates to a kind of horizontal parting, core running channel, and the grounding ball casting moulds of the many castings of a type are used to cast the abrading-ball of all size.
At present, the casting of abrading-ball typically uses the ordinary sand casting die casting, and the abrading-ball that adopts the sand casting mould to produce must add quench hot and temper can be used.It is to be noted that the grounding ball casting defective is that Technology for Heating Processing can't remedy, the sand casting method makes abrading-ball exist following congenital deficiency: 1. microscopic structure is loose, and crystal grain is thick; 2. micro pipe, shrinkage porosite are serious; 3. be prone to sand washing, dreg defect.Although adopt the heat treatment means to strengthen, the performance of abrading-ball also is difficult to reach instructions for use, in use is prone to and peels off, distortion and broken.
Along with novel wear-resistant Development of Materials and application, the material of the used abrading-ball of ball crusher is brought in constant renewal in and is regenerated, and that adapt with it, advanced permanent mold casting mould also constantly comes out.There is the people that spheroidal graphite cast-iron is used as anti-friction material as far back as the seventies, adopts a kind of metal type dies to cast nodular cast iron grinding ball, improved the performance (referring to accompanying drawing 1) of abrading-ball.But this graphite is wearing no resistance of abrading-ball, far can not satisfy industrial application requirements, and this mould is owing to be vertical-parting and metal mold running channel, the burning of mould and the phenomenon of metalling run out are more serious, production efficiency is lower in addition, and a type can only be cast two balls, and is not suitable for casting bead.
Along with developing rapidly of high-chromium white cast iron, this mould shown in Figure 1 is that abrading-ball no longer adapts to cast carbide, because it will make abrading-ball produce serious shrinkage porosite, shrinkage cavity.There are not the crystallization characteristics that right China ink is separated out according to alloy spoken parts in traditional operas material, must a kind of novel Mould for casting ball of development.The inventor had once developed a kind of single ball casting mould (referring to accompanying drawing 2), and this mould suitable for casting alloy spoken parts in traditional operas material has been eliminated shrinkage cavity, shrinkage porosite in the abrading-ball, has guaranteed the quality of abrading-ball substantially.But shortcoming is: 1 teeming formula makes bits easily enter die cavity; 2 are not suitable for casting bead; 3 production efficiencys are low, and a type can only be cast a ball, and the duration of pouring is long, and molten metal is easy to oxidation, the requirement of incompatibility large-scale production.
The purpose of this utility model is that a kind of improved permanent mold casting mould will be provided, and it can cast the abrading-ball of φ 30-φ 120.
The purpose of this utility model is achieved in that the metal type dies with the casting die ball is designed to include the metal type dies that model, drag and core are formed running gate system.Its architectural feature is that two block models are respectively equipped with plural at least die cavity up and down.The die cavity of each model is a hemi-spherical cavities in the part near the model periphery, part near model center is provided with a semicircle orifice, the vertical plane of this circular hole and spherical hollow space intersect, spherical hollow space is clipped a part, at model central authorities vertical direction an insulation core running gate system is arranged, upper and lower model is connected by some alignment pins, closely cooperates.The inner chamber of insulation core running gate system is made up of the part spherical hollow space of an inverted Y-shaped hole and its underpart, and spherical hollow space is identical by the part that circular hole cuts away on this spherical hollow space and the model.Core insulated pouring system is arranged in model, and the spherical hollow space of its spherical hollow space and upper and lower model is formed a complete spherical hollow space.
Fig. 1 is the spheroidal graphite cast-iron of a prior art metal mold model structure chart.
Fig. 2 is the single ball casting pattern of the metal mold structure chart of prior art.
Fig. 3 is a metal mold model structural representation of the present utility model.The last model of 1-, 2-drag, 3-core composite pouring system, 4-model orientation pin.
Fig. 4 is hardness (HRC) distribution map that casts out abrading-ball with metal mold model of the present utility model.
Describe details and working condition in detail below in conjunction with Fig. 3 and Fig. 4 according to the metal mold model that the utility model proposes.
Metal mold of the present utility model is by last model 1, drag 2, and core composite pouring system 3 and model orientation pin 4 are formed.Last model 1 and drag 2 are respectively equipped with some die cavities, each die cavity is a hemi-spherical cavities in the part near the model periphery, part near model center is provided with a semicircle orifice, the vertical plane of this circular hole and spherical hollow space intersect, spherical hollow space is clipped a part, at model central authorities vertical direction an insulation core running gate system 3 is arranged, upper and lower two models are closely connected by some alignment pins 4.Upper and lower model 1 and 2 adopts steel alloy, gray iron, ductile iron material to make.Pin 4 usefulness metals are made, the core running gate system as shown in Figure 3, its inner chamber is made up of the part spherical hollow space of an inverted Y-shaped hole and its underpart, spherical hollow space is identical by the part that circular hole cuts away on this spherical hollow space and the model.Core composite pouring system can adopt oil-sand, water-glass sand, resin sand to make.
Permanent mold casting mould of the present utility model adopts horizontal parting, the core running channel, and a type is cast more, guaranteed the quality of abrading-ball, improved the serviceability of abrading-ball, improved the hardness (see figure 4) of abrading-ball, through the HI-chrome cast iron for grinding balls of this kind die casting, omitted high-temperature heat treatment process, can under as cast condition, directly use, and can satisfy the instructions for use of large, medium and small cement mill, not broken ball, indeformable, ball consumption rate is dropped to below 50 gram/(tons cement).
